My first girlfriend had an identical twin

It was every middle schooler’s dream! A hot chick with an identical sister and all the fantasies you could imagine. So there I was during summer break, I decide to head over to my girlfriend’s house. I walk in and I’m instantly greeted by whom I thought was my girlfriend, but little did I know how confused I was, and what a trip awaited. One thing led to another and next thing you know, I fucked her dad. The resemblance was uncanny!
