April Fools Sibling Competition

... right breast, all pointy and sticking out, slipped into the crack so far that Diane had to shrink away so it wouldn't touch her arm.

"Fuck me, you animal," Mrs. Lambert said passionately.

His first stroke forced Mrs. Lambert hard on the box, creating another set of vibrations in a cross direction and further stimulating way. Mr. Lambert was an adamant lover, and each stroke was more a pounding that fucking. Mrs. Lambert, who at first had been thrusting back in kind, mitigating the vibrations, gave up as he sped up and just took the pounding train wreck on her clit, passing the energy onto the siblings.

By now, the siblings had reached the point of no return. Neither one could prevent the instinctual thrusting that our ape ancestors instilled in us. James thrust with his cock burying it in Diane, and then ashamed would stop, only to unconsciously do it again. Diane, too, began to hump back in spurts as she began to succumb to the eroticism and need to finish.

How wrong they were.

"I want to see your face when you cum," Mr. Lambert exclaimed.

"Yes, yes, Will," she squealed.

Thankfully, that vibration stopped as Mr. Lambert pulled out. Mrs. Lambert then turned around and backed up to the box, leaning against it.

Touching her pussy she cooed, "Mama needs a good fucking, Willie."

"Here to oblige," he said, lifting her butt as she gripped him with her legs.

If the vibrations were bad before, they were worse now. James figured honestly that the Lamberts would have tipped the box over if he and his sister hadn't been in the box weighing it down. Each stroke was like the box was hit with a sledgehammer. Stroke after stroke, Mr. Lambert pummeled Mrs. Lambert ...
