My Cuck Little step-Brother

Your step-sis comes back from a date, and you pester her to tell you all about it! She gradually realizes that you're getting off on hearing about her getting fucked by her boyfriend, and she has some fun telling you all the dirty details whilst humiliating you for being such a gross little cuck pervert for your own big step-sister! She spots you trying to jack off without her noticing, but eventually allows it and even plays with her pussy in front of you so the two of you can cum together!
