Kiara Cole has had a thing going on with her adopted brother Seth Gamble. When Seth sends Kiara a Valentine's Day card, Kiara's stepmom, Brandi Love, walks in on her reading it. Brandi insists on reading her stepdaughter's card, but is horrified to realize the explicit content is from Seth! Brandi sends Kiara to her room, then pulls Seth's pants down and bends him over her knee so she can spank him. Neither of them knows that Kiara is watching them and that she likes what she sees.

Kiara offers Seth an apology blowjob for ratting him out, which temporarily soothes Seth's feelings. His warm and willing sis gets on her hands and knees so he can get in on that from behind, but Brandi walks back in and catches them in the act! She tells Kiara to stand against the wall, telling Kiara that if she wants to act like a slut she'll treat her like a slut. She lectures Seth, then announces that she is now in control of their fucking. When Kiara shows how she sucks Seth's cock, Brandi can't control her disgust. She decides to teach Kiara how to suck her adopted brother off like a champ.

The mother-daughter bonding goes a step further as Brandi teaches Seth how to fuck his sister properly. She's not doing this just for her own health, though, so she ensures that each of her stepchildren uses whatever tools they have at their disposal to satisfy her own cock craving fuck hole. Once Brandi has decided that she and Kiara are satisfied, they deliver a double BJ to Seth until he can't hold back his cumshot and jizzes all over both girls. As they all enjoy the afterglow, Brandi reminds both kids that she's in charge and that they shall not bang behind her back.
