My highschool gf's half sister wanted me bad for some reason. Got to the point where we shared nudes over msn messenger. A couple weeks later we all drove a couple hours to go pick her up. We all went for dinner, she sat across from me and legit pulled my cock outta my shorts in the restaurant. She also went up my shorts while I sat in the back of the van. Reached around the seat and up my shorts she went lmao. It was so fucking hot.

Fast forward a few months and things aren't going the best between gf and I. She was older than me so she was going to college and I could tell she was ready to move on. We had an argument at the bar one night, I stayed and she went home early. By the time I got there, she was asleep in the basement waiting for me. Her fucking sister was in the upstairs living room fucking waiting for me. This was our first bit of time "alone". She sat there And stroked my cock so intensely, like she fucking loved watching my foreskin go up and down. I couldn't wait long so I pulled her tits out (massive fucking teen tits, like incredible tits, all my buddies wanted to fuck her lmao) and literally fucked her face forever. I heard something upstairs so I went into cum focus mode and literally fucking soaked her face and tits. I preceeded to clean up, then head downstairs to try and sleep without waking my gf... Minutes after I pass out I get woken up by my gf sucking my cock.

At this point, I was 99% sure my gf was cheating on me. So the stuff with her sister was like the best revenge ever. Following night, I sealed the deal with her sister. 18yr old pussy that was so fucking tight I didnt think I'd be Able to go all the way in. Fuck man such good memories.

So, I didn't say shit about what I did until she broke up with me, and I found proof she did cheat. And I'll never forget it, I got her a job where I was working at a GM Plant. She was texting me and being a nasty fucking cunt and I sent this "yeah well your sister sucks a much better cock than you do" and blocked her. Talk Bout main character walking awY from an explosion lmao.

So the gf was actually my best friends step sister too (yeah, wild shit lmao) so I heard bits and pieces over the years. I literally destroyed the relationship between the sisters and their mother. But tbh, the sisters always hated each other. Rivalry bullshit. I speak to my ex these days, seen her mother a bunch. And I don't think the sister visits much at all.

If I was able to do it all over again, I'd meet the sister sooner so we coulda had more fun tbh 😅
