What a surprise for this girl when she finds her brother's dick inside a box of donuts. Damn, how clever the guy. We have to give him a prize for the idea. The bastard goes with the box in front of his little sister and she can't resist: she wants a donut. He tells him to close his eyes and catch him without his hands, sucking first to choose what he wants. So when her sister starts licking her donuts, she ends up trying her brother's cock. And since she's already turned on, she sucks and then invites her to fuck her in exchange for the other donuts.
