Family Fun

Lexi dropped to her knees, and she moved in, lying on her back in front of Greta, and she shuffled her bottom closer to her on the blanket. As she did so, Greta moved in, putting her own face in between Lexi's legs, clearly about to go down on her cousin. As she did this, Aiden stood momentarily, undid his belt and dropped his jeans and underpants to the ground. Then, he knelt and moved in behind Greta, and mounted her, doggy style. It probably took less time to happen than it did to even describe, but just like that, my nephew was fucking my daughter, Greta, from behind, while she went down on his sister.

"He's fucking her!" I said, in astonishment, but Kelly's response, was, "Well spotted, Sherlock," without even turning away.

"I hope they're playing it safe," I said, because I had seen no sign of a condom.

"They're smart kids," Kelly said, still watching, "I think they'll be careful."

"I fucking hope so," I said, but watching two people fucking, even from that distance, was still having its effect on me, and my cock was now made of bone. This thought passed through my mind fairly quickly, but I half wondered what effect this might be having on Kelly, but as I looked over her head, watching our kids in a threesome in the moonlit field outside, she poked her bottom back deliberately and bumped my hard cock again.

"You've still got that thing," she said, still with that playful tone, and she reached back again, darting her hand into the fly of my boxer shorts and squeezing a second time.

"Leave it alone," I said, but she used her thumb to rub across the head, smearing precum and gently fondling it. The feeling was delicious but I took her hand by the wrist a second time and pulled it from my shorts.

"You've gotta stop doing that!" I said, keeping my voice low, but with a giggle in her voice, Kelly replied with, "Well, somebody needs to take of hold it if you're not going to."

"Come on, leave it alone," I said, but I still did not move back. This time, she reached back, darted her hand into my shorts once more, and smeared the oozing precum down the shaft in a twisting movement with her palm, and actually started rubbing it in a wanking motion, lubed with my slippery precum, and for a brief second or two, the feelings were almost too good, and I gave in, letting her rub it a little longer.

"Feels like you need this," she said, still keeping her voice low. Once again, I didn't answer as I basked in the sweet sensations of her hand on my cock, but then, what could I say? A moment or two later, without saying anything, Kelly took a quick breath, and suddenly reached down with her left hand, and grabbed the hem of her satin slip, pulling it up in a bunch and exposing her shapely, rounded butt in the half light from the hallway. There was no way I expected this, but she brushed back the fly of my shorts with her right hand, pulled my rock hard cock through the fly and moved back, guiding her pussy to my cock and impaling herself on it. I know I should have pulled back, and removed myself from the situation, but I did not, and the most basic instincts took over, whether I liked it or not. In truth, I have to say I liked it, and I did the most natural thing in the world when a man's cock is inside a woman's pussy, and I began to thrust into Kelly, and she bent forward and began to rock her hips, taking my cock deep inside herself, as she started to moan.

I knew what I was doing, but at the same time, I felt like it was not really happening. I mean, how could it be? I was fucking my sister from behind, as we looked out the window at our collective adult kids engaged in a sexual threesome out in the field next to the house. That just doesn't happen.

Kelly's pussy was snug and slippery, and fucking her felt almost unbelievably good, as she started to breath more heavily and bow her head, while the sweet sensations flowed through both of us. I took hold of her by the hips as we fucked, and she lifted her head, took a shuddering breath, swallowed, and said, "Ryan, are you gonna cum?" She spoke quickly, and took another breath.

I hadn't really looked ahead that far, but I said, "Are you safe?"

"I had my tubes tied," Kelly said, taking another breath, "when the kids were born," with another gasping, shuddering breath as we fucked deep and fast, and she added, "I thought two was enough," breathing again.

I did not answer, but I kept thrusting into her pussy from behind, unsure if she was giving me the go-ahead to cum inside her. "It's okay," she said, exhaling the words as though she was sighing as she spoke, "Just cum when you're ready. I want you to cum inside me, Ryan. Just do it."

I kept on thrusting, as the feelings built up in me, but Kelly lifted her head, swallowed hard, took another quick, gulping breath, and said, "Just one thing."

"What's that?" I answered, my voice sounding tight as we fucked, and she said, "Can you lose the shorts?"

Fucking her felt so good that it was hard to stop, but I ceased my thrusting and pulled my cock from her. I wasted no time pulling off my boxer shorts, stretching the elastic waistband over my erection and letting them drop to the floor. I kicked them off to the right and then took hold of my cock in my right hand, reaching between Kelly's legs with my left hand to feel for her opening. I felt her pussy hair and then the slick, slippery entrance to her pussy, and I pushed my rock-hard tool inside, going balls deep in one thrust. Kelly's back stiffened and she shuddered as I filled her abruptly like that, and she made a strained noise in her throat, but she thrust her pelvis backwards, inviting me to resume our illicit coupling. I reached around her pelvis with my left hand, with my palm on her right hip, feeling her pubic hair brushing on my forearm, as my right arm went around her waist. I felt the soft warmth from her breasts on my right arm through the satin material of her slip, as I held her body to myself, fucking her hard and deep.

"That's the way," she sighed again, and with what had just gone on, I had not looked out at Aiden and the girls for a while, but I looked out over Kelly's head to see that Aiden was now totally going for it. He had his hands on Greta's back, taking his weight as he drove his cock into her, looking like he wasn't far from the home stretch. He was thrusting hard, pushing deep, and there was no question that Greta was taking some serious cock. Her head was moving around between Lexi's legs, and she was obviously giving her cousin's pussy a good working over while she was being royally fucked from behind. They were an amazing team, you had to give them that, and forty yards away at the window, Aiden's mother's pussy was dealing with some hard cock of its own. It was a disgraceful situation, but at the same time, five people were giving and taking immense pleasure in each other's bodies, and it was not over yet.

I was holding Kelly close, embracing her to me as I drove my cock into her, and the two of us were now breathing heavily. Kelly bowed her head, and arched her back, and with a strained and shuddering voice, she said, "Ryan, I'm close! I'm gonna cum soon." It almost sounded like a warning.

"That's great!" I answered, "Just go for it!" As excited as I was, and as good as it felt to fuck my own sister, somehow the thought of seeing her cumming was deliciously appealing, but Kelly lifted her head back, with that shuddering voice, and she said, "It feels so good," taking another gasping breath, "Gotta cover my mouth," taking another quick, shuddering breath, and quickly finishing, "Or I might scream." She bent down with her right arm on the windowsill, and rested her head on the back of her hand. I guessed she had her mouth over the back of her hand but there was no time to think about that because as she bent forward, the angle of her pussy changed and I seemed to hit an extra sweet spot. I went straight to short rapid strokes, giving it all I had, but not thrusting deep any more. I was in the zone. Kelly had made it clear she was there to be fucked, and I was there to honour her commitment to taking my hard cock, and the load it was about to leave behind.

I looked out and I could see Aiden was close as well. He was jackhammering Greta's pussy with his own short, rapid strokes, and she was arching her back, taking all the cock she could get from him. It looked like he was in deep, but stroking short, his seed locked and loaded, ready for deployment. At the same time, Lexi was moving her head from side to side. She was on her back, legs bent, feet flat on the blanket, totally presenting her pussy to Greta, and I could hear sounds from her but I could not hear what she was saying, if she was saying anything at all. She could have been moaning in ecstasy, but at the same time, her mother was doing some moaning of her own. Kelly had the back of her hand in her mouth, her head down as I fucked her from behind, and she suddenly made a muffled yelping sound, and I saw Lexi turning her head towards the house, as though she heard something, but then she looked back up towards Aiden, as he fucked Greta from behind. She seemed to say something quickly, and then she stiffened on the ground, lifted her hands over herself, twisting her forearms and clenching her fists as her orgasm swept through her. I saw all of this but I did not miss a beat as I kept up my short-stroke fucking action deep inside Kelly's cunt, and suddenly it was Kelly's turn to cum. Her whole body stiffened yet again, and she took another three of those shuddering breaths, pushing her face into her hand as she cried out, muffling her screams of pleasure.

Just as Kelly's lovely body was being wracked with orgasmic pleasure, I saw Aiden ramp up his own pace, fucking Greta harder than ever, as she lifted her head from Lexi's pussy and cried out in the night as they came together. As I watched Aiden and Greta going for broke out there through the window, my own orgasm hit, and a massive wave of pleasure engulfed me. I held Kelly tight, fucking her to the very end, delivering my sperm into my sister's birth canal in two, three, four hard spurts, with each spurt accompanied by a bolt of pure bliss, as I pumped my load into her.

As my orgasm faded, Kelly seemed to relax, and she stood up as I withdrew from her pussy. My cock flopped as it was released, and Kelly took hold of the windowsill. She sighed, "Ohh, Ryan, I'm dizzy after that," so I took hold of her from the side, with my right hand on her left shoulder and my left arm behind her back, and I walked her gently backwards a few steps to her bed. She sat heavily on the side of the bed, and with my knees trembling after the hot sex we had just experienced together, I dropped to kneel in front of her.

Our faces were close, but neither of us spoke for a moment, and then Kelly said, "I can't believe we just did that," but she moved in and kissed me on the mouth. Somehow, it seemed the thing to do after what had just happened. It was a warm, post-lovemaking kiss, and we held it for a brief moment, but practically as soon as our mouths parted, I heard Lexi's voice at the bedroom door.

"Mum, you okay?" Lexi said, as she stepped into the semi dark room, and saw me, kneeling in front of her mother, as Kelly sat on the edge of the bed. "Ryan, what are you doing?" she said, sounding surprised when he saw me. Then, she looked at her mother, with mild concern in her voice, and said, "You okay, Mum? I thought I heard you calling out a few minutes ago. Thought you might be having a nightmare."

"It's fine," Kelly said, "We were just talking."

"Really?" Lexi said, "At this time of night?" She looked at me, kneeling oddly close to her mother in the darkened room, as though it seemed strange, and it probably did, but then I saw her eyes drop to my white shorts, lying on the floor near the window.

"What's that over there?" she said, and my stomach dropped as she stepped over to look down at my shorts, and then at me, naked from the waist down, kneeling in front of her mother. She looked at me, then at her mother, then back at the shorts on the floor, and said, "Omigod! What were you guys doing?" She looked back at us.

"Well, you ought to talk," Kelly said, and for a moment I saw a look on Lexi's face, as though she was about to ask what Kelly meant, and pretend innocence, but then I saw her eyes move to the window as she realised what we had been looking at. "Oh, no!" she said, with a sinking tone in her voice, and she looked back at us and said, "You were watching us."

"Yes, we were," Kelly answered, a little seriously. I didn't say anything because there was nothing for me to say.

Lexi's face brightened up as she put it all together, and she said, "So, you guys were watching us out there, but you were going for it in here yourselves at the same time. How deliciously perverted!"

"Maybe you shouldn't let the others know," I said, "I think things are weird enough as it is."

"Won't say a word," Lexi said, smiling mischievously, but she stepped over and put her hand on my shoulder as I knelt on the floor and added, "But, you know, if you and I got together for a little uncle time, if you know what I mean, it would help me to keep my lips sealed even better."

"Come on," I said, "let's not start getting carried away here."

"You just did it with your sister," Lexi said, smiling down at me, "so doing it with your niece wouldn't be a big stretch."

"Come on Lexi," I said, "Let's not go there right now."

"I don't mean right now, but it would help me keep my mouth shut in future," Lexi said as she smiled, but Kelly interrupted and said, "How long have you three been doing that sort of thing?"

"A few months," Lexi answered, like it was no big deal, "We're all grown adults, you know."

"Yeah, I get that," Kelly said, and she waved her hands around like she was trying to think and talk at the same time, and she said, "I guess I can't talk now, but, umm, you and Aiden?" She tilted her head, and gestured towards the window.

"Yes," Lexi said, "But we're safe. I'm on the pill and nothing's gonna happen. It's just good, clean fun." Then, she seemed to stop and think, and added, "Well, dirty fun really, when you think about it." She smiled again.

Kelly sighed and said, "As long as you're safe." She looked at me, and I realised I needed to ask about Greta. "What about Aiden and Greta?" I said, looking up at Lexi.

"All sorted," Lexi answered, "Greta's got one of those implants in her arm. Nothing's gonna happen, okay?"

I was having some conflicted feelings right about now. I had just had some hot, hard and totally satisfying sex, but the problem was that I had also just fucked my sister. Then, I had been caught in the act by my niece, who I now knew was fucking her own brother, and licking my daughter's pussy into the bargain, and to add icing on the cake, I now knew my daughter was fucking her cousin, but I couldn't say anything because of what I had just done. The weirdness and irony were just piling on.

My train of thought was interrupted by Lexi, who said, "I think I better go out and keep the other two from coming inside until you guys get straightened out," and she headed out the door, but she stopped briefly on the way out to look at me and say, "Just remember, Ryan, we need some uncle and niece time together." She smiled and disappeared out the door.

Kelly looked at me with a straight face, and said, "Oh, shit."

"I think I'd better go to bed," I said, not knowing what else to say. I got up and walked to my boxer shorts, picking them up and putting them on without speaking. "I'll, umm, see you in the morning," I said to Kelly, who was now lying in her bed with the covers over herself, and she said, "It's all okay, Ryan. It's not a g big deal."

"Okay, " I said, quietly, not convinced, as I walked out of her room and into the spare bedroom. I got back into my own bed, and lay there for a few minutes. My body felt physically satisfied, but my mind was wrapping itself around all sorts of ideas. I had just fucked my sister, and I had enjoyed it. The cum I had pumped into her shared its DNA with the walls of the pussy that had milked it from my cock. How weird was that? It's not supposed to happen, but it did, and I was part of it, and now I had to deal with it. I wasn't sure what the future would bring, but all I could do was go to sleep and leave those things until tomorrow.
