What she doesn’t know is that he has had a crush on her since long before their parents even met. He is not about to let the fact that she is now his stepsister get in the way. In fact, it means you are closer than before and you have a chance to make your move. You know that she dates a lot and enjoys VR porn cosplay. Not all of the guys she goes out with are into it as she is, so you decide to buy her a special outfit. It is one she has wanted for a long time and she is so excited that she tries it on in front of you without thinking. When she is all dressed up in her sexy cow outfit she notices you staring at her and the huge bulge in your jeans. She smiles and teases you with a toy, but can’t help but wonder how your big dick tastes. You are happy to let her suck it and then turn her around to fuck her pussy from behind. Loving her new outfit and the cosplay she saw in a recent VR porn movie, Octokuro begs you to put it in her ass and give her a proper fucking. Of all the guys she has fucked, you are the kinkiest and really get into her play. She loves the way you feel in her ass and you love watching her play with her big tits while you bang her. Finishing with the cosplay, she does some milking of her own, working out every drop of cum from your cock onto her face. After searching for so long, she has finally found her perfect kinky cosplay partner, her own stepbrother.
