My girlfriend at 17 was super hot. She was 16 and a real maniac in bed. She was up for almost everything – and we basically had a pornstar relationship, as only hormone-driven high school students can. She was amazing – she did me in my sleep, wanted me to do the same, oral, facials, anal, you name it. The only thing was that she was a real homo, or lesbo, phobe and hated porn.
Her sister was a year older than me and was equally hot – actually, she was hotter, because my girlfriend had medium sized breasts and her sister’s breasts were huge. She basically looked like a more porn version of my girlfriend.
Anyway, she moved in at my apartment for a while and watched porn non-stop. She’d wear really tight clothes and once I even came home to find her masturbating to porn on the couch. She just lay there and let me watch while I jerked off. Pretty soon, we were watching porn together and masturbating, and then we started fucking to porn. Then one day she came up with the idea of a threesome with her and my girlfriend. I totally knew my girlfriend wouldn’t be into it – aside from the lesbophobia, this was her sister we’re talking about. So we hatched a plan to get my girlfriend drunk one night and see what happened.
That weekend, we sat at my place and all got drunk – well, me and my girl’s sister pretended to. It didn’t take long for my girlfriend to be drunk and she started getting really horney. I took her into my room and started going down on her. While her eyes were closed, I let her sister take over. My girlfriend opened her eyes and looked down, only to see her sister’s face buried in her pussy, and me fucking her sister up the ass. She yelled at us to stop but, by then, it wass too late. Her sister got a bit aggressive and held her down. When she was done, my girlfriend ran into the bathroom and locked the door while I kept on with her sister. At the time it was a huge turn on, but I feel really guilty for what I did to my girlfriend. That said, though, apparently the two now share every boyfriend they have.
