Your slutty step-sister is on the couch talking to you about her latest date and how the guy was nice but the sex sucked. She tells you she refuses to be with a guy who is bad in bed no matter how nice he is. Knowing your step-sister is a complete cock slut she continues on about how she is going on another date with a guy who looks like he will have a big dick. As she is telling you about another guy she recently fucked it casually comes out of her mouth that she knows you (her step-brother) has a big cock. She then tells you "maybe we can give it a try, see if we like it". She doesn't care all that much that you are related. Maybe it will be you, her step-brother who finally satisfies her cock addiction! (Messy blowjob, Cowgirl, missionary, doggy, cumshot)
