I don’t think any of us remember how it happened, Senior Prank Day was going great… I was casually changing some grades in the teacher’s computer while my girl Katerina blew me under the desk. Then her stepbrother Jimmy showed up with my stepsister Thea and of course, they were flirting and teasing each other as they always do… and then it kinda happened… I was really horny already because Katerina has mad head skills, but she really wanted to fuck my stepsister apparently. I mean, Jimmy and I weren’t gonna miss the show, so pretty soon we were fucking them like animals in that small classroom… one thing led to another and before we knew it I was fucking my stepsis Thea and Katerina was fucking her stepbro too.
