PART ONE - Nina is about to go to the gym when she realizes she's out of protein powder. She calls her step-son, Rion, in the room and reprimands him for not getting any from the store like she asked. He says he can go get it now, but Nina has something else in mind. She orders him to take down his pants and says she's going to milk him for protein instead.

PART TWO - Nina barges into Rion's room while he's laying down and asks if he's jerking off. He says he isn't and she says that he better not be. She grabs his dick and says this belongs to me. She gets on top of him and starts stroking his cock until it's hard, and then she puts it in her mouth. Nina wants more of Rion and she's going to get it.

PART THREE - Rion is laying on the couch watching TV when Nina comes in. She says "I'm going to the gym, you know what to do". She then rips his shorts off and starts sucking his cock until it's hard. She jumps on top of him and slides his dick into her pussy.
