Fuck stepsis on bf's birthday

Call me a fuck Champ cuz I nailed my stepsis on her boyfriend's birthday and had her thanking me for not telling our parents on her. Fucking dumb slut! I always wondered what her pussy felt like and it turned out to be as smooth, tight and slurping as I imagined. She rode my dick like a good slut, let me drill her from behind and took a big load right in her mouth. She loved it too, so now I'm gonna be fucking this bitch any time I want, no doubt!
