Dude, I was on my summer family vacation. Everything was going sweet, that is until we realized the rental our parents booked only had two bedrooms. My parents took the master and of course I had to share the smaller room with my step-sister, Sera. It wouldn’t have been a biggy, except there was only one bed in the room. How freaking awkward, right? At first we didn’t know how we were going to handle it, but once I saw my little step-sister changing into her bathing suit, I was completely turned on. I got a boner in two seconds and suddenly I found myself lusting over her. She must of felt the same for me, because once she saw my raging hard on, she started blushing big time. One thing led to another and we started to hook up. It was so dirty and hot I couldn’t control myself. I wanted to get balls deep inside my step-sister. Sera wanted it too and she shoved my cock in her tight little hole. I fucked my little step-sister like she’d never been fucked. After she came on my cock, I shot my load deep inside her. I just hope step-mom and step-dad don’t find out, otherwise their gonna be pissed at us again.
