Della Cate is setting up a kissing booth for St. Patty's Day. Her stepbrother, Parker Ambrose, comes and gently mocks Della for her idea. She asks him to help her practice. The first kiss is nice, and the second is a lot better. Before things can progress between the stepsiblings, their mom comes home.

Later, Della puts a glory hole shamrock together with a sign to insert for kisses. Parker tries with his finger and gets it sucked. He puts his dick in next and Della goes right for a BJ. Turning around, she flips her miniskirt up and pushes her thong aside so she can have Parker do her in doggy through the gloryhole.

Della reveals herself and hops onto her kissing booth for Parker to plunge back into her cooch. Getting to her feet, Della leans over the table and urges Parker to do her once again from behind. Then Della gets her stepbro on his back so she can ride him in cowgirl until she's finally satisfied. Parker stands up once again so his horny stepsis can suck him off until he covers her small tits in a nice cum shot.
