Custom video. Calling out the name Ben. Your older step sister has to take you with her to the Halloween party because of your mom and she's not happy about it. She pokes and teases you to try and get you to back out. She tells you how it's embarrassing to bring her little step brother with her. She decides to jokingly put a ghost costume on you so no one would know but when she pulls it off, something magical happened. She's in a different costume and youre now in a monster costume. She starts acting dominant but super horny. She convinces you to help her and starts with a blowjob. That's not enough, she suggests doggystyle so you wouldn't look at each other because that would be weird. Suddenly your cock turns into a monster cock and she becomes weirder, more submissive, bimbo like. Begging to ride you so you can touch her all over. You both cum and she snaps back into her dominant personality before passing out. She wakes up from her nap questioning if it really happened??
