When I was a sophomore in college, I had a 2br apt just off campus. My buddy who split it with me decided to switch schools at the end of the year, but at the same time, my sister decided to attend the same school, so she just took the second room. Seemed like a great situation. We were pretty close, and it was cheaper than on campus housing. Plus she was stoked to be able to steal my alcohol all the time, lol. My sister is pretty attractive. Only about 5'2" 100lbs, nice b cups and a cute little butt.

So before the end of the year I had a pretty steady gf, and things were great. Summer was uneventful, but it didn't take long after move in time for things to start getting interesting.

My gf would regularly hang out at our place, and we fucked fairly frequently (especially the first couple weeks since we rarely saw each other over the summer). About 2-3 weeks into the school year I started noticing the shadow of my sisters feet under the door when my gf and I were fucking. I wasn't sure what to think at first, but it quickly started turning me on more and more every time. That soon progressed to me leaving the door cracked open so she could peak. The first time she didn't come by, but the second I saw her there for a minute, but made sure it didn't seem like I noticed.

We went on like that for a couple more weeks before I gained the confidence to look her in the eyes through the door one day. I could see her rubbing herself through her shorts and a blew my load in my gf's pussy about 10 seconds later, staring at my sis the whole time. Just as I was finishing I saw her shake a little then run off to her room. Stay tuned for more 😈
