Juan Loco is looking for something in the couch when his stepsister Freya Parker gooses him from behind. Juan grabs Freya's boobs in return. Although she clearly enjoys it, Freya eventually comes back to herself and tells Juan to cut it out and that she only grabbed him because he's not wearing green. Juan snaps back that St. Patty's Day isn't a real holiday and that she's only using it as an excuse to get Mona Azar, the teacher she has a crush on, to come over to give them a history lesson.
Freya may have flounced out of the room, but Juan was right about the crush part. Later, Mona and Freya have just had a seat on the couch when Juan joins them. Mona also gooses him since he's still not wearing green, and Juan goes right for the boobs. Mona lectures Juan, who decides the proper response is to put a leprechaun hat on his dick. Exasperated, the girls decide to make out while Juan jerks off. The only rule is he can't cum.
Kissing of course leads to so much more. Soon enough, Freya is tongue deep in Mona's creamy coochie. After sharing a kiss, the girls work Juan in a double BJ to include him in the action. He gets to fuck Freya in doggy as his stepsis returns to eating Mona out. Then Mona goes for a reverse cowgirl stiffie ride before getting on her knees so Juan can do her in doggy as she laps at Freya's twat. On her back and cradled against Mona's big bosom, Freya spreads herself wide open to fuck her stepbrother until he pulls out to nut on her muff. The girls share their treat with one last round of sweet kisses.
