[MF] – Sex with my wife’s younger sister

This story happened a couple of years ago when I was 28. My wife’s (26) sister Haley (22) had just gotten out of a long term relationship and was staying at our house for a week while she got back on her feet.

As a little bit of background, my wife has been okay with me sleeping with other girls in the past, but only if it was something she had arranged. This had happened only a couple of times.

Now I had been lusting after Haley ever since I started dating her sister. She is, and always has been a bit of a brat (that’s what being a younger sister will do to you I guess) but my god is she gorgeous. She’s about 5’2, brunette hair just past her shoulders, a slim but still somewhat curvy body with perky probably C or D breasts and a very cute face.

Having her in the house was torture. Watching her walk out of the bathroom with her towel wrapped around her as she walked to the guest room with her smooth legs poking out from underneath the towel. It didn’t help that she likes to wear low cut tops. I’m sure she must have caught me staring, because she would shoot me these teasing looks every now and then.

Finally, it was Haley’s last day in our house and my wife was still out at work. I was just hanging out in my bedroom playing on my tablet when the door opened and Haley walked in wearing a bathrobe.

“Hi Haley, what’s up?” I asked.

“Well,” she said. ”I wanted to thank you for letting me stay here this week. I’ve seen you looking at me…” she finished as she slowly started to tease the opening of the bathrobe wider.

“Um, Haley, I’m not sure what you’re talking about,” I stammered.

“I’m sure you do,” she answered as she opened her robe and let it fall to the floor, revealing a matching set of blue lacy underwear. I momentarily lost my ability to speak, but the obvious bulge in my sweatpants gave me away.

Before I knew what was happening Haley was beside my bed, had pulled my pants down to my ankles and was knelt down with her mouth on my hard cock. I didn’t say anything at first, just enjoyed the feeling of her warm wet mouth on me. The feel of her tongue sliding around the head of my cock. I had fantasized about this so often before.

“Haley, we shouldn’t be doing this, what would you sister think,” I said as I finally snapped out of it. She lifted her head up and looked at me.

“She’s the one who gave me this idea silly,” she responded before going back down on me. Her head bobbed quickly up and down, her hands cupping my balls and playing with them as she sucked.

I was fully into this now, and wouldn’t have been able to stop even if I wanted to. I didn’t want to waste this opportunity by only getting a blowjob and I was about to cum soon if I let her continue, so I gently pusher her off and stood up. I reached around her and undid her bra, letting her fantastic tits fall out. They were so perky I couldn’t believe it. They were pale white, with small little pointy nipples. I bent down to suck on them and felt them harden in my mouth. I then pushed her back onto the bed, reached down and slowly peeled off her panties.

I looked down on her as she spread her legs for me, showing her freshly shaved smooth white pussy. She pulled the lips apart with her fingers so I could see her pink opening looking back at me.

“I want you to fuck me like you fuck my sister,” Haley said, looking at me with her wide blue eyes. “I need this so bad… please.” That was all I needed to hear before linin the tip of my cock up with her pussy and slowly pushing inside her. God her young pussy was so tight, I almost came right there.

I started thrusting, slowly at first and then harder. Haley’s eyes started to roll up into her head and all you could hear was the sound of her panting and my balls rhythmically slapping against her ass. Suddenly, she pushed me out of her and turned around, getting on her hands and knees without saying a word.

I moved up behind her and started up where I had left off, slamming my cock in and out of her tight little pussy. There was a mirror in the room and I could see her perfect tits hanging down and swinging every time I thrusted. I slowly inserted my thumb into her tight asshole while I fucked her. That was apparently all she needed as she cried out that she was cumming. I kept fucking her, feeling my own orgasm slowly buidling.

“Oh fuck, cum all over me, I want to feel your hot cum!” Haley cried out. I quickly pulled out and shot rope after rope of cum all over her ass and her back. I’ve never cum so much as I did then. After that we both collapsed for a few minutes before cleaning up.

“That was just a one time thing,” she said. “I just wanted to thank you for letting me stay here.” She moved her stuff out shortly thereafter and neither of us has mentioned it since, but I think about it all the time when I’m jerking off.

When my wife got home she asked me how my day was with a big smile and a mischievous glint in her eye. I told her it was fine and she responded back, “I bet it was.”
