Swinging With My Sister

My wife and I recently began swinging, and we went from never having tried it to doing it once per week now. The issue is, we're swinging with my sister and her husband, which means I'm now sleeping with my younger sister (all adults here...).

We were visiting my sister and her husband, Laura and Ted, when the subject came up. My wife, Becky, and I were enjoying some drinks with them and we were all pretty hammered towards the end of the evening...not sick drunk, but in no shape to drive. We were sort of calling it a night when Ted said "Going to feel strange sleeping in my own bed tonight." My sister Laura gave him a playful shove and a stern gaze and said "Let's not go there, shall we?" I got curious and asked "Go where...?"

Long story short - Ted was referring to the fact that most times they had another couple stay over, it was so they could partner swap with whoever they were entertaining. They were swingers and we were hearing about it for the first time. I was floored. They are both fit, attractive people, but Laura in particular was always straight-laced and trouble-free growing up, even became an accountant, and here she was admitting to her brother and his wife that she liked other cocks besides her husband's. Becky and I were both speechless, but then Becky laughed and said "So I guess I should be offended you aren't taking me to bed, Ted."

She was half joking but half daring Ted to suggest the two of them hook up. We haven't been swinging before, and we're faithful to each other, but we have toyed with the idea in role playing other people. Never Ted though, and certainly never my own sister.

The banter continued and it came back around to Becky's question. Ted said "You know, I'd take you to bed in a heartbeat if Lance (me) would let me." We all started looking around at each other, and I inevitably started looking at Laura and she at me, knowing this was a step beyond swinging if we were to participate. Becky didn't seem to fully grasp it all at first. "We can't do that" Becky said "Lance and Laura would be stuck out here while we were in the bedroom..." Ted laughed and Laura began explaining to Becky "If you're getting Ted, I'm not going to bed alone. If we're already swinging, Lance and I could get along just fine by ourselves."

It bothered Becky the most. "Eww," she said "you would sleep with your own brother?" Then Becky looked at me "And you, you'd fuck your own sister?" Laura and I both admitted in that moment we would definitely have sex together if Ted and Becky went off to do it. "Okay" Becky finally said "but I can't watch that, it's too weird." We looked around the room again and Ted said "Okay then, let's do this!" Ted got out of his chair, came over to Becky and took her bu the hand to lead her from the sofa back to their bedroom. Laura and I sat still the whole time, watching them leave to go fuck, probably not thinking nearly as much about them as what we were about to do.

Laura stood up and I looked her over. She has a great body as a runner and college cheerleader. She was also very obsessive about her weight, so she looked just so. She stood there in skin tight waist high leggings and a cropped sweatshirt and just looked so hot. I think it helped that she was wearing glasses to give a little of that hot librarian look at the same time. I didn't feel self conscious about my looks either, I'm athletic too so we were probably pretty compatible that way...other than being related, I guess.

Laura looked down at me sitting and said quickly "stand up." I did and she went down on her knees in one fluid motion, right in front of me and started undoing my fly. Just the action of her kneeling there unzipping me made me instantly hard. As she fished out my cock I ran my hands through her hair and grabbed onto her hair to help guide her to my shaft. She was the perfect cock sucker. Her tongue darted in and out and she ran it along my shaft to my balls, then back to the head again. She slowly stroked me with one hand and pulled me into her mouth. I moaned in heaven and she stopped for a second "No cumming in my mouth, I want you to fuck me and squirt it all in me, understand?" She smiled and I laughed and nodded "Yes, ma'am." She went back to work and I did have to make sure to slow her occasionally so not to blow too soon.

She stood up and took off her sweatshirt first. Her breasts were perfect melons, not too large or small and perky brown nipples. I bent over and began sucking each nipple hard, moving back and forth between them. Laura helped by holding my head firmly to her tits so I'd suck as hard as possible. I used one hand to go between her legs and massage her pussy through her leggings while she was grinding against my hand. We kept this up for another few minutes and then she pushed me back for a minute. "Help me open up the sofa bed." she said.

We frantically opened the bed up and stripped. From there we pounced on each other and started first in a 69, sucking and licking for a while and also calming down a little so we wouldn't rush too much. The bed sucked, it dipped in the middle. Laura had obviously used this bed before because she then said "lie cross-ways at the end of the bed. I want to ride you." I laid on my back with my cock in the air and she came over and expertly lined me up and took me into her wet pussy. I cupped her breasts and pushed her to sit up straight on my dick while I looked at her for a minute. "What?" she asked. I replied "You are so hot, I can't believe I'm fucking my sister." She replied "just shut up and fuck me."

I tried to last as long as possible but at some point it almost turned from a love-making session to a competitive brother-sister fight. I'd slow her down and she'd say "No you don't, I want it all" all and she'd ride me harder or bounce up and down with her tits flopping in my hands. I finally had to admit I couldn't hold out and said "Here it comes!" I pulled her down on my shaft by her hips and held her tight as I began pumping semen deep in her. She ground into me hard and we made wet sucking sounds between our privates as she and I both came. She was wet before but the excitement of having me in her was more than she first admitted. I could feel her juices running down the side of my hip as I continued cumming. When we finished she fell down on top of me and we had a deep passionate kiss. Then she said "You're right, I can't believe I just fucked my own brother."

We kissed and fucked on and off throughout the night, just a small blanket from the sofa to cover us from time to time. Laura was like a sex addict. She licked me clean from our first session, then asked if I'd mind eating her out. I've eaten out my wife after sex, so didn't really mind. We ended up fucking again, missionary the second time, then more rest and foreplay, then I did her doggie late in the night or maybe early morning. By that time I was just erect from being excited, my balls were pretty much drained.

After our third time we both fell asleep, only to be woken up a little later by Becky and Ted. They found us spooning under the little blanket, still naked and wet with sex. "aww", Becky said, "You look cute together, too bad you're going to hell now." Laura teased her back more playfully than I would have imagined "Oh you little hoar, I'm sure my husband took good care of you last night." "Oh, he did." Becky replied "but we spent a couple of hours listening to the two of you go at it...must have been a lot of sexual tension growing up." I laughed and Laura slapped me on the butt. "Don't encourage her!" Laura said.

We all agreed that we would definitely do this again. When Laura and I had a minute alone she said to me "You have to be one of the best fucks I have ever had." I replied "Thanks, too bad we didn't know sooner." Then Laura said "It's probably better we didn't know too early...Mom and Dad would have had a cow if they caught us." I'm sure the Thanksgiving holiday will be a lot of fun with Becky and I shooting Laura and Ted looks across the table...my parents not knowing what their son and daughter have been up to.

I have similar true experience.

Mid nineties, mid summers day. Our cousin was visiting us. Well, she was visiting our moms aunt, who was living a large farmstead where everyone in our family almost daily visited.

My brother and couple of his friends, and me and our cousin were hanging out and drinking at home that night. Our parents were away and would stay out for couple of days.

Our cousin got drunk and went in my brothers room with one of his friend. They were having fun, and my brothers other friend decided to leave. Now there were only four of us.

Me and my brother had played around often, but we had not yet had real sex. I was extremely jealous when we heard them having sex and my brother, being too shy to stop them, were cursing how he couldn't go to his bed. We were laying on our parents bed and because getting excited by their muffled sounds, we decided to fool around, very carefully.

We handn't kissed yet because I had thought it to be too dirty, but then I began to kiss him, I was kind of acting like he was my boyfriend. I wanted to have sex because our cousin were having it! Soon his hands were on my tits and then in my panties and I was jerking him off through his jeans. I wanted to hump him, but we couldn't to not to make too much sound. He soon stopped, telling me he was about to cum. Of course we didn't want that to happen to not to get caught. But I was enjoying my orgasms. I felt amazing but my panties were drenched!

But when we heard them to quit it, I asked my brother to steal few condoms from our fathers stash. I felt ashamed and anxious, because I had to go quickly to change my panties in toilet, but I couldn't really wash myself.

Half a hour later my brother, having blue balls, went to sleep to his ruined bed. His friend had left to his home and I hoped our cousin would had left with him. But me and our cousin were sleeping in my room. I didn't dare to ask her how it had felt, but I was secretly happy that I had got something too and I was extremely anxious to do something soon.
