Lily Adams and her stepbrother Bambino have invited Ms Faris over for a study session. The girls are bored with their work, so eventually Lily invites Ms Faris to start gossiping about her love life. Bambino isn't interested in hearing about his sister and her friend talking about their tight little pussies and big cocks, so Lily goes on the offensive about the size of Bambino's dick. Eventually Bambino whips it out to prove it's not small.

Ms Faris is properly impressed by Bambino's dick, but Lily refuses to back down. Lily gets on her knees and starts sucking to prove it's not too big to fit in her mouth, and Ms Faris joins her because she just wants to suck it. Once the girls are done deep throating Bambino, Ms Faris peels off her shorts so Bambino can give it to her. He fucks her from behind while Lily watches and sucks her friend's titties. When Lily sees how good it is for Ms Faris, she decides to take Bambino for a test drive of her own.

Lily only needs a taste of her stepbrother's so-called tiny cock to know she's nice and hooked. She and Ms Faris take turns riding him, alternating between who gets Bambino's face and his mouth. When they've had enough, they get on their knees together so they can go back to sucking and stroking Bambino's fuck stick. When he gives them a double facial, Lily must finally admit that she's pretty into Bambino's big juicy load even though she still swears his dick is tiny.
