“Ready?” asked Jack.
“Uh huh,” answered Betty as she opened her mouth and pressed it to the underside of his cock and Joan’s cunt.
Billy had moved to the other side of the bed to watch Jack’s cock coming out of Joan’s cunt. There was only a fraction of an inch through which he could see the point of coupling as well as Betty’s mouth and probing tongue.
Jack lifted his ass and his cock came out of Joan’s cunt with a pop and the juices followed with a gush. There was no way Betty could have caught the whole flood, even if she could have had Joan’s hole completely covered before Jack’s cock slipped out. The gush filled her mouth and ran down across her jaw. It wet her hair and dropped to her shoulder, running down across her titty as she moved around to get lined up with her daughter’s cunt so she could start using her tongue to hit her clit and plug her hole.
Billy crawled up toward the head of the bed and threw his leg across Joan’s shoulders, straddling her and resting his hips on her titties. He slipped a hand under her head and lifted it as he guided his cock to her mouth with the other hand. When she took the head of his cock into her mouth he put both hands under her head and started lifting it until his cock struck her throat and lowering it until her lips were in the groove behind his cock head.
Billy watched his cock slipping in and out of his sister’s mouth and adjusted his knees further apart and his cock further up toward her mouth. He had found the range and started lifting Joan’s head faster, jacking himself off with her lips, tongue and throat. He leveled out and held a steady pace. Her tongue provided a friction against the bottom of his prick that gave him extreme pleasure without making him come too soon.
Jack watched his girlfriend being eaten by her mother and screwed in the mouth by her brother. He smiled. His cock had been satisfied and he looked around to see who he could satisfy.
Jack moved around to the foot of the bed and lay on his back. He reached above his head and pressed Betty’s thighs apart. She felt his hands and spread her knees. Jack slid on his back until his he was between her thighs and he put his hands on her hips and pressed down. She lowered her cunt until it was resting on his mouth.
He pushed his head back, raising his mouth until he could cover her slit with his mouth, running his tongue along her slick gash. Betty sighed into Joan’s cunt and lowered her butt until she was pressing her pussy down hard against the probing tongue.
Joan was still dizzy from the fucking Jack had given her and having her cunt eaten out as soon as Jack’s cock had slipped out was an added bonus. Her belly was still quivering from being fucked and hot, slick juices were still running down to her pussy. Her nipples were hard and the thin hair on Billy’s hips was rubbing them lightly. The fact that there was a cock in her mouth kept the excitement level high in her mental and physical feelings. Billy’s thin lubricating juices draining down her throat sent shivers of ecstasy down her spine.
