I Cum in My Fat Step Sister Mouth Before Visiting Her Boyfriend

I enter the bathroom while my stepsister is getting ready to go out on a date with her boyfriend, I start kissing her neck and touching her while she gets excited, then she gives me a blowjob, and then I fuck her doggy style against the wc. When i can't stand me excitement anymore, I cum in her pretty little mouth while she enjoys a load of semen in her mouth. The BBW is a slut, she loves to cum in her mouth and taste the semen.
