He barely has time to make a sound before Lucy lifts her hips and sits back down, impelling herself on his cock. They both let out a loud moan as the pleasure rushes over their bodies. Lucy slowly starts rocking up and down, back and forth. His hands find her hips and he guides her up and down on his cock. He reaches up taking one of her hardened nipples in his mouth. He sucks and nibbles her delectable breasts for the first time in his life. Lucy continues to increase her moans as electric waves move from her nipples to her pussy.
Lucy gets carried away and lifts her hips too high and his hard cock slips from her wet pussy and flops against his stomach. She wastes no time in sliding him back in to her pussy as far as it could go, soliciting another groan and moan from both of them. Her lips lower and touch his as he thrust back up into her paradise! Their tongues wrestle as he can feel her nails gripping at his back, trying to dig in. He knows it won’t be long for him as he continues to pursue her pleasure. He can hear her squeals of pleasure getting louder and louder in his ear.
Then, almost without warning, Lucy grips him tightly! Her nails grip his flesh, her legs quiver around his hips. The sound of the squealing and moaning will never be forgotten as his sister cums and cums! His mind flashes images of his sister straddling him. He is deep inside of her, the waves of pleasure racing through their bodies! David erupts with a spasm of pleasure like none he’d had before. Lucy moans loudly and David feels a torrent of cum explode inside his sister's body! Another thrust, another blast of cream and another groan from both of them. David gave three more thrusts before the waves of pleasure ebbed from his body.
Lucy falls forward on top of his chest, and buries her head in his neck. Their breathing is hard and labored. Slowly she releases him from her vaginal grip and his cock slides from her hot silky pussy. She can feel the sweat on their flesh as she caresses his back. She fights hard to make sense of what has just happened. Had she really just fucked her own Brother?
When they finally catch their breath and Lucy lays with her head on his chest, with his arms holding her, and her legs straddling his hips, she proclaims,
"That was incredible! It was so much better than I ever dreamed it would be."
"Yeah," He panted. "It was fuckin' great, sis! Just waited another few minutes then we can do it again.”
“I want to lay right here and do it over and over; all night long until I can’t stand it anymore,” she moans softly in his ear.
