"What, Mom? You want to boink him?" She brought me up instead. "Just once a month, we have family night. The second Saturday until you two move out, we have sex in front of each other, and then..." she said, before peeking at Greg. "We switch." "You want to swing once a month?" "Yes, it seems like a small ask for your parents being so supportive of you two. Just once a month, and the rest of the month, you two may keep your clothes on around us. So, is it alright?" "And if we disagree, you withdraw your support?" "No, but it would show us you put in some good faith to us. You two were unplanned, and we got married because of you two. So, I think we have something to offer you. We can be your role model couple, and we can stay extra close too. So, what do you two say?" Then I went to Greg. "I know you want to do it with mom again, but this is big." "I agree, Angel. It's just once a month, it seems weird, but why not? We're siblings that are engaged, and they're already gonna be involved in wedding planning. I want it, but we both have to want it. I can deal with dad doing it with you, but can you handle mom doing it with me?" "And we're fucking in front of each other too?" "Do you want to set ground rules?" "No, if they're our parents, we should just be able to have sex with them. Have fun with mom, and I'll do the same with dad," I told him, before kissing him. "I love you." "I love you too, and I'm gonna marry you and make sure you're always my queen." "Okay," I replied, smiling. "Don't get her pregnant."' "I'm on the pill, Angel, we're not gonna give you two a sibling," our mom made clear, taking Greg's hand. "Don't worry, I won't steal him away, just please him," she put on the record, taking him to their side of the couch. Then our dad came to me and sat next to me. "There's another man in this room and loves you dearly," he told me, leaning to me. "May I kiss you?" "Yes, Dad." He smirked and kissed me unlike a father. He didn't feel me just yet, but I knew our mom and Greg were getting busy too. So, I took our dad's hand and set it on my tit. He suddenly parted his lips. "Wow, these are nicer than I remember," he complimented me, squeezing them. Then I took his rod my hand. "And this is harder, too, Daddy," I said, before peeking at them. "Don't fall for her, Greg, you're still mine. She might have great jugs, but remember whose you're marrying." "Yes, Angel," he moaned, failing to look at me. I watched him slather her nipples for a moment with her palms on his head, but then I kissed our dad again and he helped himself to feeling my pussy. He held me close and let his fingers thrust in and out of it. I stroked his member in the process and felt the veins in it going haywire already. He managed to kiss me on and off a few times as he played with my cunt, and I gave him a mean hand job. "Oh, yes, dear son, suck on your mommy's nipples and make her cum. Squeeze those knockers, and get some milk ou of them too if you want. I'm your mom, so I'm not gonna judge you." I laughed a bit, and then took our dad's hand. "I taste my juice all the time, let's say it gets someone off," I confessed, taking it into my mouth. "For good reason, Angel." "Damn straight," Greg added, getting off the couch. "Holy shit, you're to die for, Mom," he congratulated her, taking his cock in his hands. He aligned it with her cunt and stuck it in there. "Oh, Mom, you're the MILFest MILF in existence," he moaned, thrusting it. "Damn, you're hotter than hot, you're steaming and letting MILF fumes come off all over you." "Okay," she laughed. "I think that means he's attracted to you, Mom," I mentioned, getting on top of our dad. "It's okay to be attracted to your kids, isn't it?" I pondered, guiding his dick to my slit. "It's completely okay if there's no foul play, Angel," he told me, feeling my butt. "Anything sexual has to be loving and consequential. What you two have is definitely that, so cheat on each other with your parents, it might put an extra spark in your marriage. At least seeing your partner with someone you love and respect, it can reignite any lost passion, I can tell you that. Don't be turned off to look at each other, it can hot and loving. Just don't do it too much, got it?" "I understand, Dad." "Good," he added, going to my rack. He feasted on it and my pussy dealt with toll of his schlong devouring it yet again. My cunt wasn't used to his bigger pecker, but I made due. I jerked a bit and had his johnson follow my slit around. It took a bigger toll on my pussy, but I didn't mind. I had to peek at Greg, and he was giving it to our mom. He held her thighs hard, and kept his junk going in and out at a constant speed. So, he had her boobs shaking, but I could tell he kept focus on her. "I love you, Mom, you're amazing." "Thank you, son. Even if you weren't involved with Angel, I'd love to get with you. Afterall, you are quite the hunk since you take after you father." "Thank you too, Mom," he moaned, before leaning to her to kiss her. "I can fuck you once a month, that's fine with me." "Don't forget about her, she has to be okay with it." "I know, Mom, I know. I'm gonna treat her like a queen." "But don't forget about yourself, she has to return the favor." "I understand, Mom, and your boobs are perfect. They feel wonderful on my hands, and chest." "You should feel them on your butt." "I can't wait," he let out, before getting back up. He fucked her hard, and didn't say anything. He was the same way when he fucked me for the first time, so he was sucked in, but of course, in a good way. He made her boobs jolt, but he still eyed her. I tried my best to keep my eyes on our dad, but it was hard. Between hum fucking me, and me wanting to see them, it was hard. I could only guess I might've been just a tad jealous, but I was still having fun with our dad. I made myself keep moving somewhat, but our dad glued his face to my jugs. He went to both of them and made me feel extra good. He licked on sucked on each nipple flawlessly. So, he got me to cum all over his cock, and he was getting off on it. I had him convulsing a bit as well, but he held me in place and continued his pleasing. I wasn't sure if I could last as long as our mom dealing that that cock, but I was gonna find out. He made sure to give me plenty of eye contact too when wooing me, so I gave it back when I could. Yet, this wasn't ordinary, but extraordinary. I loved Greg more than anyone else in the world, but still seeing him fuck our mom was hot beyond what I could imagine. He enjoyed her as I enjoyed our dad. "I do love your boobies, Angel," he told me, coming to me to kiss me. "If he ever tried to tell you to get them done, I'll beat the shit out of him myself. Damn, he's related to you, and he gets you all to himself?" "Well, if you want me once a month, then you gotta let Greg have mom once a month too. Why, do you want to fuck me again, Daddy?" "Well, I hope it's okay," he said, peeking at them. "Maybe next time we can be alone." "I can deal with that, but you better stay on the pill, Angel. We'll pay for it if we have to, but incest babies aren't healthy." "We know, Mom, so you better stay on the pill too, don't let Greg knock you up either. He can shoot his load like a shotgun, so if he shoots when you're not using protection, then you will get pregnant. Even though I'm on top of dad here, I'm sure he can blow like a cannon, right, Dad?" I pondered, glancing at him. "Holy shit, I love you, Angel," he moaned, before pasting his lips to mine. We made out like horny and passionate lovers. He wrapped his arms around me and got my tits crushed on his chest. "Make out with me, horndog," we heard our mom let out. I couldn't look at them, but I was certain they were kissing too. The whole time, he still managed to thrust his dick a bit, and punish my slit a little bit more. His hands made it down to my butt and clutched those buttcheeks too. He knew how to kiss a woman too, both using his tongue and lips flawlessly. Not that I was truly jealous, but he gave me a taste of something else. I took the love with a grain of salt, and enjoyed every second of it. After another couple of minutes, I parted my lips. "Wow, you're a hunk, Dad." "A hunk and a half, Angel. There's a reason we stayed together after having unplanned twins," she told me, before Greg back off her. He got down on his knees in front of her and went to her cunt. "And you're quite the elegant woman, Mom," he praised her, before going down on her. "Thank you, son," she moaned, covering his head with both hands. "You love yourself some MILF pussy too? Just remember, you have to be faithful to your sister, and get her snatch. Keep her satisfied, but make sure she craves more." "Okay, Mom," I giggled, standing up on the couch. "Let's see how well your hubby can eat a woman out now," I said, placing my palms on the wall. "Yes, dear daughter," our dad mentioned, setting his palms on my thighs. "You're gonna fall on top of me, but I don't care," he added, before letting his tongue out. I immediately he urge to collapse, but I flexed myself the best I could. "Holy shit, Dad, you're good," I moaned, hitting the wall. "Trust me, I know," our mom agreed. So, both of us women reveled in the serene pleasure of getting our cherries eaten. My dad was right, I was gonna fall, but I fought like hell to stay upright. He slathered my lips down there, and had me tingling all over too. Once again, he proved to be better than Greg, but I didn't blurt that out I just took all the thrills he wanted to give me. I could see his forehead, but not his mouth. I still felt what his mouth was giving me quite vividly. My juice came plummeting out, but he glued his face to my cunt. He didn't even leave much room for his tongue to stay out in the open. So, my twat was practically hiding his face. Even though I couldn't see it, I could feel it. I convulsed a bit, and nearly fell, but I was stubborn. I pushed my feet down as much as I could to keep good stance, but of course, our dad was out to make me fall it seemed. I wasn't gonna give him shit for it, but it was true. "Yes, yes, yes, Daddy, that's good, that's so good. My beaver is on fire now. Keep going until I do fall on you. It'll hurt me more than it hurts you, but you'll take care of me." He nodded, but he couldn't stop pleasing me. I had to glimpse at them too, and Greg still wooing our mom too. He proved that maybe he was in competition with our dad. I had to giggle, but didn't make myself fall. Yet, I knew no matter what, it was just a matter of time. Still, I wanted to show off as much as I could. I moaned nonstop, and hit the wall so much, I knew Greg and our mom had to getting a little jealous. I couldn't worry about them, an I could only focus on our dad going to town on me. I had some tears spark too, but staying upright was a priority. So, I held back on screaming and moving around too much too. Although, our dad cut that short when he gently pulled me down to him. "You're still perfect to me, Angel," he todl me, before kissing me. "Now and forever." "You're biased like him, but thanks," I told him, before switching places with him. Then he went down on me and our mom too took all the pleasure she could take. "Hold your mommy's hand, sweetie." So, I brought my hand to hers an we took the sweet thrills together. If that wasn't enough, she leaned her head on my shoulder. So, she wanted to be as close as possible. I couldn't turn her down, and I relished the results. "You like eating out our daughter, Brian? Do you? She is a sweet young thing, and mean always love them younger, don't you?" "What, Dad, have you gone after younger ladies before?" "No, but some younger ladies have tried to get my attention. I am a happily married man in case you spying on us having sex didn't give that away," our dad made clear, taking a break. "We're sorry, Dad." "Don't worry, Angel," he told me, coming to me. "You may watch again if you want, but get our permission first," he warned me, before kissing me. "Okay, Daddy." "I love you." "I love you too," I muttered back, before he went back to my muff. "And your financee loves your mom too," he added, prior to going down on me. I had to peek at him. "Yes, you do love mom, huh?" He nodded and made her feel good. "Yes, use that tongue inside and out on me, and get my juice all over your face. I'll clean it off for you if you want, I don't mind cleaning. I'll get every drop for you." He nodded again, and made her moan. I was letting out some moans too, but not as big. I was still dealing with the serene notion of everything that was going on. Nevertheless, it was still a huge mindfuck to deal with then. Our dad used his tongue on me flawlessly too going back inside and out of my snatch, but I knew he wasn't the man I loved so much. I could only guess why I wasn't going as nuts, but even still, afterward, I'd make him remember who his priority number one was. I had no idea how much either of them could eat us out, but they were pussy licking warriors it appeared. They wanted to show off for each other, and both of them clamped their pals on our thighs. So, they both got our juices plastered all over their faces. I saw it on both of them, and it did make me even hornier. I melted, so to speak, but still held myself together the best I could. He was letting out his moans, i knew he was losing it too. Giving me pleasure was certainly taking a toll on him too. I could tell the same of Greg because he looked the same when he ate me out in the past too. All the signs were there for us working: we loved each other, had sexual chemistry and our parents supported us too. I saw Greg going to town on our mom, and it only made me more attracted to him. I already loved him dearly, but he was making me want him even more making our mom feel so good. I saw our mom reacting to the thrills too, which made me want her, in fact. We hadn't told our dad that happened, but I decided not to without our mom's consent. In any event, she showed she was one sexy MILF, and he couldn't handle her forever. So, after 10 minutes, he let out dad win. "Damn, you're good, Dad, how can you still be going?" "It takes practice, son," he made clear, coming up to me and setting his palms on my butt. "I mean, if you have a woman this stunning, you can't be perfect overnight, or even in a few months. Work with your sexy sister, and you'll turn into the great lover she craves. She's want to marry you because she loves you, so don't too hung up on making her feel good. Just demonstrate you love her every single day for the rest of your lives. He loves you, Angel, but you need to replicate those feelings. Are you up for it?" "Yes, Dad," I answered, wrapping my arms around his neck. 20 years from now, I fully intend to still be with him and still be having family nights." "Is that so? I nodded. "Thank you for being so supportive," I thanked him, before kissing him. "It means the world to us, and if I have to thank you once a month, consider it done." He smiled at me, and turned me around. I leaned forward and felt him guide his dick to my slit. "Don't get me wrong, sexual chemistry is a huge piece of the puzzle, but it's not the whole thing. You have to love each other even without it. The sexual chemistry builds it, but you need the love first. You two adored each other years before you got together, so you're good. There's a lot of work, though, so don't think you can get through this without working with one another," he explained, thrusting his rod. "And telling each other you love one another is always appreciated." "I understand, Dad," Greg let out, rising, but staying on his knees. He aligned his prick with our mom's cunt, and stuck it in there. "Damn, Mom, you're one sweet MILF," he complimented her, fucking her too. "I love Angel, but I'd love to fuck you again, you're hot as hell." "Thank you, but my boobs are down here." "Oh, Mom," I giggled. "Look at me." I arched my back and let her see my tits. "What, Mom?" "Be funny too, you sweet thing. Every guy loves to laugh. If you have great chemistry with and without clothes on, then you should survive a little laughter at one of your expenses. He loves your moneymakers, maybe even more than you." "That's not funny, Mom. I love her for her." "I guess you need the lesson too, dude. You should be able to joke and laugh together too. If you're afraid everything may lead to a fight, then you're hostage to each other. You're not that, are you?" "No, Mom," we both answered. "Fair enough." Then I reached over to Greg and kissed him. "You're not perfect, you never will be, and that's no joke. That doesn't make me love you any less. Your dick isn't as big as I'd like it, but it's more than enough for me. That's the truth, Greg. Something else that's true: we'll never be a perfect couple, not because we're siblings, but we just won't be. The last true thing I'll say in this moment is that I just want you being with me and wanting that forever." "Okay, sis." "We may have incredibly great sex with our parents, but it'll be nothing compared to us being together. I'm always gonna want your seed on my hooters, and you kissing and cuddling with me afterward. I'm sure I could do it with 50 other guys, and you'd be better than all of them. I haven't gotten to feel the spark with anyone else, except dad, but I'm certain there's not gonna be anyone else that loves me as much and is as sexually attracted to me to as you." "Okay, sis." "Is fucking our parents once a month okay with you?" "Yes, but no sleepovers." "Fair enough," I added, before I kissed him. "If we're not gonna be cheating on each other with our parents more than once a month, don't be cheating on me with my panties more than that." "You see, you're learning," our mom gloated. "Mom, don't do that." "Okay, understood." "It's not anyone's fault me kissing you made you want me, it just happened. Now put your cock back inside mom an give her a huge cumshot." He nodded and kissed me again before going back to our mom. He stuck his rod back in her snatch and fucked her again. He smiled at me somewhat as he did, so there were connections between us that were ironclad. He leaned to kiss me yet again. "You're my world, Angel." "I know, but fuck our mom and give her your cum, she wants it." He kissed me yet again and got back to it. I could see it all over his face, he didn't want our mom. He was enjoying himself, but he wanted me more than ever. He focused on our mom somewhat, but he had to keep an eye on me. I blew him a kiss and he did the same, but we didn't speak for a few minutes. We just enjoyed the taboo joy, and ran with it. Our dad kept his cock moving in and out of my cherry, and he massaged my butt as well. "You might love him, but I love you too, dear. Just don't forget about me." "I won't, Daddy," I assured him, peeking at him. "Let me suck my juice off your dick." "Yes, babe," he moaned, before I took it into my mouth. "Yes, you're a dicksucking queen," he complimented me, feeling my head."Every guy loves getting his cock sucked, and you're showing that you know exactly what you're doing. I say marry this woman, son, and never let her go. You will regret it in more ways than one, I promise you," he warned Greg, before peeking at me again. "I just mean shit, use those hands too. Just like your mom, one sexy woman regardless of age." I nodded and rose to him. "Is that why you want to see me alone, Dad?" "I might be," he confessed, feeling my butt. "I love having sex with my daughter, but it's too bad we're both taken." "Was that a joke, Dad?" "Yes, but this isn't: you're intoxicatingly beautiful, Angel. This family night isn't even over, but I can't wait for the next one." "Well, remember, I'm taken, Dad," I reminded him, before kissing him. "Now fuck me again," I told him, before getting back into position. "Fuck me like you'll die if you don't, Dad." He couldn't turn me down, so he stuck it back in there and made my pussy sorry. He let his prick thrust nonstop for me and certainly had me aching down there. I didn't care, though, I was having too much fun. "Yes, Mom, you're a flawless dicksucker, too." I had to peek to see, and she was deep throating him a bit. He couldn't help, but to adore her even more. Once again, I felt some jealousy, but it made me melt to see them bonding so much too. We were gonna be one close and horny family. "Yes, I know what a great blow job artist your mom is, Angel. She is to die for, but don't take her for granted. That is the biggest mistake you can make any relationship. So, make sure you appreciate and love each other more than life itself. Nothing and no one can be more important. Don't worry, we won't try to put a wedge between you two. We want you two to work, so work." "Yes, Dad," we both answered. "Kiss each other." We leaned to one another and kissed again. Then our mom came up to him. "You'll be the first incestuous couple in the family, so you better make it work," she warned us, stroking his wood. "You may feel me up, I'm only your mom." He did that and kissed her. "You two promise you won't try to tempt us, though?" "What do you mean, with sex?" "Yes, we have to work, but we don't need you two trying to bribe us." "Okay, we understand, we do love you two kids, and in more ways than one," our dad told me, before pulling me to him. "I can see how you'd think we might do that. You are a breathtaking young woman, Angel. I know you've never been with another man, other than me, but be sure to be good to him. Most women as ravishing as you like to toy with guys and become uninterested after a while. Some play hard to get, and seemingly quit the relationship when the guy still wants her." "I'm not gonna do that to Greg." "Good," he added, before kissing me. "As much as I want to do it with you every single day, we're both taken, but right now, we can still have fun," he told me, before fucking me again. He didn't ram me that time, but kept it somewhat slow. "Oh, son, you have some tongue," our mom moaned. I had to see her standing with him right between her legs. He ate her out with purpose and made it count like nothing else. He was just as crazy about her as vice versa. We were a happy and horny family, and what we were doing proved it. Greg and I had such intimacy and chemistry, and we were able to share it with our parents. Even if it was wrong, it was still right. I focused on Greg making our mom feel really damn good. I saw her trying to stay upright, and she moaned like mad. "Did you want to watch them, Angel?" our dad pondered, pulling out. "Yes, Daddy," I answered, getting on my knees facing them. I got about a foot away and saw Greg eating her out up close. Then our dad stuck his wood back into my cunt. It was harder to watch them then, but I wasn't about to deny him fucking his daughter. So, I took it with a grain of salt, and cherished the sight before me. "Oh, are you showing off for your sister now? Do you want to remind her what she'll be getting when she marries you?" "Yes, Mom," he muttered, before leaning to me. He kissed me and let me taste all of her juice off his lips. After a moment, I parted my lips. "Now that we're engaged, you're gonna be taking me out on more dates. You gotta show you people you scored this hot piece of ass." "Don't talk about yourself like that. You're a beautiful and respectable woman. I'll take you out more if that's what you desire, but as a great woman I loved being with all the time. Not just with other people watching." "Okay, drama king," I branded him, before kissing him again. "I think you're a stud for how well you can please mom." "Okay, thanks," he giggled, before going back to our mom's snatch. After a few seconds, I pushed our dad's cock out and went to Greg. I pulled him to me and kissed him again. "Don't be upset, just be my horny brother that loves me that he desired to fuck me. I know you love and respect me, but that doesn't mean you can't love every second of plowing me, making me moan and then giving me your white stuff." "I know, sis. I'm not upset, I just don't want you referring to yourself like that. If I show you off, then you'll be a queen, not some other way of calling you a hooker." "Whoa, don't say that," our dad warned him. "Okay, I'm sorry." "It's okay, I guess I found one of your buttons, huh?" "Yes." "You were supposed to kiss me." "Sorry," he apologized, before kissing me. "So, we can be honest with each other, and not have consequences." "Good, sis, I do like having sex with mom, but I still don't like sharing you." "It's just once a month, and mom is a stunning woman." He nodded and kissed me. "Okay, let's stay close," he suggested, before having our mom sit down on the couch. They were right next to each other and then we both got down on our knees in front of them. He places his palms on her thighs. Then he went to town on her, and got her to feel his head right away. Then I took our dad's cock into my mouth and he felt my head. "Oh, you two can get along greatly," he moaned, rubbing it. "The perfect brother/sister couple." We both nodded and gave our parents oral sex. Needless to say, we needed to bond while making them feel good. So, I let my hand to his and we held them while we continued to commit felonies together. I let my lips thrust off our dad's dick slowly, but I made sure to pressure it well. We looked at each other from time to time too, but we didn't speak. We just eyefucked each other when we could, and felt the love building too. What we were doing unnatural, but oh so loving. I used my other hand to hold his prick hard so I keep it down. Yet, he was losing it, and gonna go nuts in due time. In the mean time, I cherished making him feel good with Greg doing the same to our mom. I couldn't see him eating her out, but with her moaning and shaking, it was easy to paint the picture. She had a nice bush just like me, and he dealt with it. I saw him pushing it to the side before, so I had to envision he did it again. I wanted to see the action, but I kept myself focused on our dad. He wanted to bond with me more than anything it seemed, so I had to give him what he wanted. I tried to push my lips down even further, but it was difficult at best. I heard him moaning as well, and doing it fondly. I could only imagine how good he was feeling, but I knew he was loving it right back. He needed to jiggle a bit back and forth, but didn't make me fall off his dick. I didn't try to go over the top, but made it clear I was gonna please him during our once a month times together. His veins were going apeshit, so he was gonna need to shoot soon, but until then, I bonded with him and waited patiently for him to spew. Every guy loved getting his dick sucked, but with those two, they were biased as hell. I knew I hadn't been with anyone else, but I could already tell it was true. All the while, Greg continued to perfect the act of slit licking on our mom. "Oh, yes, dear, son, you're making me cry now. That's so damn good, it's unreal. She must've been teaching you extra well. She's prepping you for something big, so she loves you dearly. So, make sure you show her the love in other ways too. You showing me some real love now, and you're bonding with your sweet sister. So, I must ask: are you two gonna be fucking like rabbits after you get married?" "We'll live our own lives, Mom," I made clear. "Okay then." I came to him and brought him to me. "We'll work because we love each other, and have you two helping us along the way. Even before we hooked up, we got along, and now we're mature enough to be a couple. So, we're up for it," I explained, before kissing him. "I know how he treats me with no one else watching. I'm sorry I interrupted you, dude, you were going to town on her." "Anything for my sister," he put on the record, before kissing me and going back to our mom. He ate her out like a pro. I wanted to go back our dad, but Greg stole my attention. So, I leaned on top of him and got a closer look. I knew exactly what it was like to have him eat me out, but seeing from him on her was something else. "Do you feel my boobs on your back?" "Yes, Angel." "Wow, you're a pussy eating master, and I get you all to myself. What could be better?" "Your father fucking you from behind," our dad responded, before he guided his prick to my cunt. He stuck it in there and made me push onto Greg a bit. I couldn't tell if that distracted him or not, but he was still making her feel good. I couldn't focus on them, but I still tried somewhat. Even still, Greg didn't get freaked out by what was happening. I could only guess our parents were exchanging eye contact, but I was still too busy watching Greg eat out our mom like he'd die if he didn't. Our dad clutched my buttcheeks hard and made me go even harder on Greg. Yet, he couldn't stop, except when she pulled him up to kiss him. "I love tasting my juice off your lips," she muttered, before kissing him. "Feel me up while you kiss me." I saw that happen and our dad let his cock thrust a bit faster. He moaned like he was about to cum, but it seemed like a tease when he didn't. I wanted to look back at him, but when I knew he wasn't going to yet, I pressed myself even harder on Greg. Although then they parted lips and he went to her tits. "It's alright to love your mom, every part of her, Greg. Your sister is okay with it, so have fun." He nodded and slathered her nipples. Then I slowly got off him and had our dad follow me to the our side of the couch. I rode him again, but reverse cowgirl style that time. Greg fingered our mom as well as licked her nipples. "Yes, you two will be a perfect couple. You get one another, and support each other well too. I don't even know what else to say." "Nothing, Mom, actions speak louder than words." "Fair enough." "Damn right, I agree," our dad moaned, helping me thrust my cunt. "Once a month, wow, days are gonna drag on, but I'll live." "You loved fucking me that much, Dad?" "Yes, is it that obvious?" I giggled and kept my slit going. It was hurting, but I still didn't care. Having him fuck me was still quite the treat, even if I thought my heart was about to stop. I had sweat going down all over my body, and my heart wanted to stop, but I didn't want him to stop. I wanted him to have the time of his life with me if need be. He loved me almost as much as Greg, but still, it was hot as hell. Feeling any family member get off on me was something, even my mom. Truth be told i couldn't fathom on the why, but the very fact it was true was something else. I had my cunt going off his dick like mad, and it was hurting nonstop, yet, I couldn't stop it even if it was 10 times worse. Our dad couldn't see them, but my tits were shaking like I was on a trampoline. I had to check out Greg and our mom, and they were still having the times of their lives too. I still didn't let them steal my attention. I closed my eyes and focused myself on making our dad have to shoot. Both of those men were well trained, and ready to go all night if need be. Nevertheless, they were gonna lose it at some point. So, our mom and I made them go to their limits. "Yes, lick your mommy's nipples and finger her too. You love me so much, then do it and make me cum even more. Don't give me any mercy, give me all you have." I giggled somewhat, but didn't peek at them. I felt our dad clutch my thighs harder and prep me for more. I could tell he wanted to give me a river seed if he could. So, he built up his loas as much as possibly could. "If I never told you I loved you before, Angel, I love you to Pluto and back. I swear, I love you, mom, but you're making me want to have an affair with you." "Don't say something you can't take back, Dad." Then he pushed my slit off his cock and he turned me to him. "I'm sorry, Angel, but you're an angel in every sense of the word. Nothing and no one can take that away, I mean that," he made clear, before kissing me and feeling me up. "Your mom and I swear, we will not ask you to do this more than once a month, and if you want to stop, you ma tell us. We just love you in a way we shouldn't. You know what we mean, don't you?" Then I took his dick in my hands. "Of course we do, Dad. We're not judging you, and we expect you to do the same. It's not freaky for any of us to expect that. If we can't be voyeurs, you can't be either, got it?" "Yes," I answered, kissing him. "We should have some privacy when we fuck once a month from now on, though. Fair enough?" "Yes," our mom and Greg replied. "And no interrogating afterward." "Just save some cum for your elegant sister, Greg." "Yes, sis," he moaned, before going down on our mom again. "Oh, that's something to masturbate to, Angel," our dad muttered, fingering me. "They definitely have some connections too. It's illegal to explore them, but we can all keep things quiet, can't we?" "Yes, Dad," I moaned, leaning on him. "You do know how to use your fingers. No wonder mom loves you so much." "That and a few other tings, Angel," he muttered, pecking my neck. "Damn, I love you, Angel. You could test my limits all you want, and you'll never get me to stop. I love your boobs, by the way, and if you do decide to get pregnant with a sperm donor, I'll be wanting to feel them." "I figured, Dad." Then he smiled and turned me around to him. "Get on your knees, you sweet thing." I followed his direction, and he went right to my jugs. He instantly slathering my nipples and he managed to finger me too. I placed my palms on his head and watched him please me yet again. Just like Greg, he loved giving me pleasure. I moaned nonstop, but didn't stop him from pleasing me. He got off on it even more, and went to both of my moneymakers. If that wasn't enough, he moved and had us both get off the couch. Although, he didn't move away from my rack. Then our mom lied down flat on the couch and Greg got right on top of her. "Oh, dad does love you, sis. I could blind and deaf and I'd know that. Wow, I guess I do have competition for my hot sister." "No, yo don't, but I love you saying that, Greg," I told him, before kissing him. "So, we're okay letting them have us just once a month? We can see how horny they both can be, huh? So,are you okay with it?" "Yes, sis, I can live with that. Mom is quite the loving MILF, but just make sure you remember who you're gonna sleep with that night, got it?" "Yes, I understand." "I mean it, you have a clingy twin-sister, and I am not losing you." "I understand, sis, I love you." "I love you too, but in the end, you're my number one." He nodded and kissed me. "You're my double number one, sound better?" "Sure, smarty. Now stop letting your clingy sister distract you, fuck our mom." He nodded and went back to fucking her. I paid attention to our dad as he kept his tongue all over m nipples. He played with my muff too, and I reached down to his dick. I stroked it slowly for him, and I felt him shaking a bit. "Are you feeling good, Daddy?" "Yes," he muttered, coming up to me and kissing me. "No one will steal you away or him for tat matter. If you do decide you two want to stop giving us once a month, you may tell us. We just love our kids way more than we should. I'd love to get with you once a month for the next 27 years if need be, but not if you, him or get uncomfortable, then you may tell us. We'll stop if that's what you want." "Okay, Daddy." Then he suddenly had to blink a couple of times, and I knew it was go time. He couldn't last as long as Greg it seemed, but I wasn't gonna give him shit about it. "Oh, sweet thing," he let out, grabbing my buttcheeks. I felt his seed blast up and it came on my jugs. I didn't look anywhere else, i just watched his face as I milked him. I couldn't count his streams, but I know it was at least 4. I had to jolt a bit after each of them hit me, and I felt the taboo love hit me again. "Oh, Daddy, I knew you loved me, but wow," I told him, glancing at my rack. "You do love me. Why don't you cuddle with me?" I asked, before lying down on the couch. He couldn't resist that, so we watched Greg and his wife fuck. "Oh, that's good, son, but Terri, get on top of him an ride him. Give our son perfect access to your moneymakers." "Yes, hubby," she replied, prior to kissing him. Then she got on top of him, and then I wiped my boobs off or a moment. After that, I had our dad feel me up again, and we bonded a bit more. He was a little depleted, but I felt him squeeze them a bit. "You love my hooters, Daddy?" "Yes, maybe even more than Greg loves your mom's. Wow, you're sucking on those nipples again, and making her shake." "You do that for people you love, Brian," she reminded him, glimpsing at him. "You do that for me, remember?" "Yes, how could I forget?" "I love you." "I love you too," our dad muttered back, before kissing her. "I don't even mind kissing you when our son pleases you, that's how crazy I am about you. Our kids want to be together, and I want you with me forever." "Dude, did you forget that day nearly 20 years ago. You wore a black tux and I had a white dress?" "I remember. I remember it fondly, Terri." "Do you remember what you said when I told you I was pregnant?" "That I loved you and would love to start our family. We weren't ready, but we made it work. We didn't even know you were twins yet, but we still made it work, though." "Really, Mom?" Greg pondered. "Yes, truth be told, we did consider getting an abortion, but we decided not to, though. It's nothing we like to talk about, but you did almost did not come into this earth. We considered doing it, and just having kids a couple years down the line. We just didn't do it, not because one of us called it off. We came to a decision and that was that. We never dreamed you two would hook up years down the line, or this would be happening, but here we are," she explained, before looking at Greg. "Well, if you want kids with your sister, son, just remember,, it's harder to satisfy a MILF. Her boobs will get bigger, and will want more, but will get emotional and moody. I hope you're ready for her." "I am, Mom," he moaned, shaking too. "Oh, is it go time now?" she asked, getting off him. She got in front of hum and took his rod in her hands. "Then give your mom your seed, hunk." She milked him too, and got his cum plastered all over her rack. Our dad and I watched everything as we stayed close. I knew he wanted to lst longer tan Greg, but he was still content feeling me with him. "Oh, thank you, son," she said, getting up with him too. "Just once a month, we're not greedy, are we?" "No," Greg and I answered. "I know we can only do this once a month, but we can still have sex again tonight, right?" our dad pondered. "You're not gonna take no for an answer." They both giggled. "Just give us a few minutes to cool off." "Sure," our parents replied.
