Billy lifted from the water, sitting on the edge, of the deck, with Susan still gripping his cock.

He had seen his brother and sister fuck before, many times, but the sight still excited him. His cock throbbed in Susan's fist, and she moved her hand down to hold his young balls. At the same time, she moved her hand from Bob's cock so her daughter could take his prick deep into her pink pussy.

Pamie shoved her cunt down until she had every hard inch of Bob's cock up her pussy. She pressed and began to grind. Susan sucked in excited air, her eyes straining with heat. Holding Bob's balls in one hand, Billy's in the other, she had the weird desire to kiss her daughter's naked ass.

She dipped her face down, tickling the tip of her tongue about Bob's thigh, her face turned to watch the depth his cock went into Pamie's cunt. She ran her tongue along Bob's thigh, almost to his balls. Her face was very close now to Pamie's pretty little ass. Still she held off. She grabbed Billy's cock and began to jack furiously.

"Oooooo, I'm gonna fuck you, Bob!" Pamie squealed, and began bouncing her cunt up and down. "Ooooo, golly, you're so hard today! And my pussy is so hot!"

Susan's eyes smoldered as she watched her daughter's naked ass bouncing, her sweet little cunt riding up and down her brother's throbbing hard-on. Bob's cock became wet with the juices of his sister's pussy, glistening in the sunlight.

Pamie fucked almost violently, unashamedly. She made wild, lewd sounds as her cunt pounded up and down, stabbing herself on Bob's cock. She fucked frantically, bringing the juices to a froth at the base of his prick. Wet sounds came to Susan's ears as she stared, jacking faster on Billy's cock. She licked her lips, then licked Bob's shaking thigh again. She shoved her face closer to the churning ass of Pamie, watching her pink asshole twinkle invitingly, closing and opening as she fucked her brother in a squealing frenzy.
