When I was 18, for short period of time my step moms, half sisters, kids (read it again if you need too) moved in with us due to their mother being in jail. 2 of which were sisters (18) and (19). It was a packed house but we made it work.

On the literal first day of them arriving I could tell the older sister was the biggest slut I’ve ever seen. A total freak. A skinny long haired brunette with a thick ass. Anyways, we were all sitting at the coffee table in our living room just kind of talking and introducing ourselves, cracking jokes and just hanging out while my dad and step mom were gone to get us food. I had been eying the younger sister (18) and she was a lot less spoken. She was nerdy cute with perfect tits it looked like. She was kind of dropping hints and laughing at everything I said.

Well some how sex got brought up in our conversation and very quickly and very direct she looked at me and said “you want some head?) I was pretty nervous because no one have ever been so direct about something like that to me. I instantly started to get hard just from her asking me! I looked at her for a minute and asked “are you for real right now?” And she replied “yes. Dead ass serious.” And she was I stood up trying to hide my hard dick and she followed me to my bedroom.

As soon as we stepped in the bedroom she started taking off my pants. You could obviously tell she’s done this a ton. She look right into my eyes and started sucking my dick like I’ve never had it sucked before. She sucked my cock like a fucking porn star, just a sloppy mess in just a few seconds in seemed like. After about 2 or 3 minutes of some of the best head ever I asked her if she wanted to fuck. She said no? I was kinda confused as to why she didn’t want to honestly. But I kept my mouth shut and she continued. After about 30 seconds she stopped. With my dick still in her hand she looked at me and said “you think my sister would wanna try?” My jaw hit the fucking floor… I said “I don’t know? Maybe you should go ask her?” She got up and walked out the door.

I stood there leaned against the bed with my rock hard cock out still dripping with the older sister spit, just trying to comprehend what kind of goldmine I just fell into. Next think you know I hear the door handle start turning. I couldn’t wait to see who would be behind it. And just as you probably guessed it was the younger one. She walked in kinda nervously but went straight into it. She didnt give near as good head as her older sister but I was NOT about to complain. I mean an 18 year old boy getting his dick sucked by 2 sisters? After a couple minutes I decided I’d ask her if she wanted to fuck? Why not right? She said she would have loved too but she was on her period. Then she looked at me and said “but you can put it in my ass if you want?” I was in shock.

This was my first time ever doing anal and i immediately got excited! We swapped positions and she bent over right in front of me. Her tampon was hanging out but neither one of us seemed to care one bit. We kinda fumbled with my throbbing dick trying to stuff it in her tiny ass. Once it finally slid in I’m pretty sure my knees almost buckled 😂. I started out super slow, trying not to hurt her because she was making some uncomfortable sounds. But as soon as we got a rhythm those sounds turned in pleasant moans. I was so turned on I didn’t last very long. Maybe 2 minutes. But I never pulled out. That last thrust, I buried it in her ass and let out what seemed like the biggest load I’ve ever busted. I filled her the absolute fuck up cause when I pulled out it just rushed back out. We both just stood there and laughed and smiling over what just happens.

But then we looked out the window and there was headlights. My dad and step mom were coming up the driveway! We had no time whatsoever to even attempt to clean up the mess. She pulled her black panties back up and kept what was left of my load in her and we rushed back into the living room.

I continued hooking up with her for the duration of the time she lived with us. It was a big part of my sexual life. We both learned a lot. But maybe I’ll get to that another day if you guys liked this one! Sorry it was so long!
