Gianna Gem and her friend Allie Nicole are playing truth or dare, but the truth questions keep coming back to Gianna's stepbrother, Jason. When the opportunity arises for Allie to find out more about Jason's dick, she takes it. The girls relocate to Jason's room, where he's hiding from their game. He's not interested in Gianna and Allie's game, but he is interested in proving that he doesn't have a small dick once Allie starts teasing him. Falling to Allie's reverse psychology, Jason whips it out and then watches as Allie takes his hard-on in hand. Wrapping her mouth around it, she samples the goods before coaxing Gianna into trying her stepbrother's fuck stick. Encouraged by how good it tastes, the girls peel off their clothes and Allie takes the first ride on Jason's woody. When Gianna sees how much fun her friend is having, she goes for a reverse cowgirl ride of her own. Another double BJ keeps Jason's motor running as the girls change things up.
