Julie felt the heat of her daughter's thighs against her back, felt the pressure of Becky's cunt rubbing there. Her ass wiggled and thrust, her cunt fucking furiously on her son's cock while her daughter squeezed her tits. Becky was moaning as she looked down into her brother's contorted face. She dug her fingers into her mother's tits hard. Julie felt a slight pain, but there was more pleasure than pain.
"Ohhhhh, you feel so big in Mother's cunt, Ben!" Julie gasped. "Your cock is so big and hard and hot! This is fucking, kids! This is the way to fuck!"
Becky drew one hand from her mother's tit, reaching between their bodies. She pulled her sunsuit and panties to one side, and when Julie felt her daughter's steamy young cunt rubbing at her back, she wailed with erotic ecstasy. She could feel the throb of her daughter's tiny, but very hard, clit rubbing at her spine, feel the wetness seeping out of that sugary pussy, smearing her flesh.
"Oh, this is making me come!" Julie wailed. "My cunt… my cunt is burning up! Ooooo, fuck me, Ben! Fuck Mother's hot cunt, baby! Ohhhhh, I'm about to come!"
Her ass went wild with movement, grinding hard at the base of her son's cock. Through the boiling pulsations of her pussy, she could feel her son's cock throbbing, the head of it very, very deep inside her greedy pussy.
She smashed her cunt hard onto her son's cock, grinding in jerky movements. Her cunt gripped his prick tighter, flexing with contractions. The orgasm rippled through her naked body like suddenly released steam.
