His sister's burbled stream of obscenities spurred the naked brother on. Sliding his hands down to claw the sides of her ass, Jimmy started drilling his jam dripping cock in and out of her clit as fast as he could. The bed springs squeaked beneath them and his hard, muscular stomach slapped obscenely on his kid sister's undulating belly with every stroke.
"Harder!" Sandra hissed, frantically clutching his humping ass in a desperate attempt to his prick deeper inside her. "You're making me cum again Jimmy! Oh, fuck, my pussy's burning up!"
Her pussy erupted suddenly, throbbing around his racing cock pole, gushing out more fuck juice all over his pistoning cock. Jimmy couldn't resist the incredible auctioning pressure of his sister's cumming cunt. He fell heavily on top of her big-titted body, nailing his rigid cock as far into her pussy as it would go.
In the daze of her orgasm, Sandra felt the hot, musky cum gushing out of the crown of Jimmy's cock. It streamed deep inside her pussy channel, nearly reaching her womb.
Jimmy kept grinding and pumping savagely into her, draining his balls. Sandra flexed her fucking muscles around his spunk-shooting cock. The rest of his cream squirted into her overflowing pussy, pooling in her cock-stuffed slit and puddling luridly on the bed.
Exhausted, Jimmy rolled off of his mount between her legs, popping his fuck-wilted cock out of her gripping pussy. Sandra stared contentedly at her bedroom ceiling as the jism dripped slowly from her cunt.
There was nothing she loved more than sucking and fucking with her brother. The only thing she still craved was a taste of her father's cock. Sandra had barely had a chance to speak to her Uncle Lou and cousin Wendy, who'd just moved into the basement of their big, suburban home the night before.
They seemed like nice people, but that wasn't important. All that mattered to Sandra was that her privacy not be disturbed. She only prayed that, with two more people in the house, she'd still be able to fuck her big brother as often as she liked.
