Billy grabbed his mother's head, plunging his cock up as her mouth came crashing down. Not only was Susan sucking her son's cock now, but he was fucking deliciously into her mouth.

"Suck me, Mother!" Billy shouted. "Suck my cock! Ohhhh, my balls hurt! I'm gonna come so fucking much, Mother! You want it in your mouth?"

Susan was much too busy to answer, but she heard him through the loud roaring in her ears.

"Do it, Mother!" Pamie hissed near her head. "Make Billy come! Make him come in your mouth! Fuck his cock… fuck his hard cock with your hot mouth, Mother!"

Susan was hearing it all, but wasn't paying that much attention. Her mind was spinning wildly as she sucked desperately. With her daughter finger fucking into her hot cunt, she was already coming, shaking with orgasm after orgasm.

"Eat my cock, Mother!" Billy was shouting arching high as if trying to fuck his cock down her throat. "I'm gonna let go! Ohhh, I'm gonna give you a mouthful, Mother!"

Susan ran her hands underneath Billy's uplifted ass, clutching at his hard asscheeks, pulling his cock as deep as she could into her mouth. With a grunt, Billy came.

Susan tasted the splash of his sweet, young come juice as it struck the back of her throat. She whined with ecstasy about his cock, swallowing greedily. As she began to suck up on his spurting cock, some of the come juice dripped from the cower of her lips, but she managed to swallow most of it. She gulped wetly, her tongue flicking against his gushing piss hole. Her eyes, still closed, rolled in her head as her twat entered final contractions of agonized orgasms about her daughter's deeply in bedded finger.

Susan slumped on the deck, gasping, conic juice clinging to her lips. She felt Pamie pull her finger out of her cunt and her ass shivered. Her throat continued to burn from the spray of come juices, both from Bob's cock, and Billy's, too.
