My hot step sister was trying to take some selfies for her boyfriend. She asked me to help her to take pictures of her ass. I agreed to help and she took off her pants for the pic. She posed for the camera with her ass pointed at me and buttcheeks spread out so that I could see her shaved little pussy. At that moment her phone rang, it was her bf. She took the phone and started talking to him, still with no pants on. She lied down on the couch to talk with him and spread her legs wide open. I couldn’t take it anymore and I pulled out my hard cock and slid my dick inside her tight pussy. I was fucking my stepsis while she was still on the phone with her bf. She just lied to her that she was jogging.
