Learning that she is preparing for university vertical transfer exams, the young man makes sacrifices so that she can be alone in her room and study quietly. He takes care of everything from preparing and bringing the drinks he wants to eating. This time he sees something strange. Her stepsister is wearing a transparent, white, tight outfit. When he approaches her and tells her that she is very beautiful, when the pussy part of her tight, white tights gets wet, he immediately understands that she is craving a dick and starts to load his step sister's pussy with cum, both to help her study and load her brain with lessons, and to relieve her hormones by fucking her wet pussy.
