Let's Talk About Sex Stepbro

Your stepsister Riley Jean is worried about you. You've been feeling down in the dumps since your girlfriend broke up with you, but she can't figure out why she would've left such a nice guy like you. It's gotta' be your cock, so your stepsister takes it upon herself to find out what you're working with and give you a few pointers. Only she doesn't know that she won't need to give you ANY tips because you can make your stepsister cum on at the drop of a hat... or the thrust of a dick, in this case.
