Hot Teen Fucks Her Step Bro Massive Boner!

So two days ago I was feeling pretty good cause my girlfriend was supposed to come rest over and have some fun together. Since I hadn't heard from her at 7pm I texted her to see where she was at and that's when she told me that she had a meeting at her Sorority she totally forgot about and we would have to do that another night. The only problem with that is last week I was hanging out with my friends and when we stopped at the gas station we all bought those over the counter dick pills so we could try them and see if they really work. And I figured that night was the perfect time to try it, so now that my girl is not coming over I'm chilling with a raging boner in my room. I decided to go check on my step sister since I hear fuck her boyfriend all the time maybe she could help me with that. She wasn't really happy to hear my story but after some convincing she figured the fastest way to get rid of me was to get it over with. So I took her doggy style first before she turned around
