I (25) filled up my sis (22) after we went to a show

Me and my sister went to a show recently out of town and decided to split a hotel room. She is incredibly attractive and she has always been open and comfortable around me so I figured I might get a get peak or something witch has been the case for a few years. I was right!

She came out the bathroom in her bra and panties to grab some clothes and then changed into sexy laced top and some ripped shoots. She looked amazing and it’s all I could think about during that night.

We went to the show with some friends, got into our spot with her in front of me. At first I was off to the side a little bit. Every time she moved back a little or would jump her ass cheek with slap on my dick.

I realized I was getting a little hard so I moved behind her and stepped back a little but she ended up getting bumped back into me and my dick went right between her cheeks. I pretty she felt it because a second later she pushed her ass back against me again and wiggled a little bit.

This continued through out the night. We went back to the room after the show, All a little tipsy and fall asleep. I woke up extremely horny and cuddled up next to her. I laid my head back down but could feel her pushing her ass against me. I returned the favor and after a minute decided fuck it. I put up my phone. Slide clothes off and got behind her. I grabbed my dick and pushed it in her. It took a few times before sliding all the way in but I could feel she was already wet as fuck. It didn’t fell weird or wrong. Just felt good. She was moaning and panting and it reminded me of when I use to hear her masterbaiting. I turned her around and give her a few good pumps before I finished. I grabbed my phone, set an alarm and we both fell back asleep.
