She pulled at her son's ass, and soon Jerry was pushing his cock down as she lifted her cunt, drawing up as she lowered her ass. They were fucking each other, and Marcy was afraid and elated and ashamed and trembling with increasing ecstasy. She was feeling things she had never felt when she had gotten fucked before. Things that were strange and delightful and good and delicious.

She began to make purring sound deep in her throat. She moved her hands, shifting her son's robe, sliding her hands under it to cup the cheeks of his naked ass. Her own ass pumped with his stabbing cock, slowly and not in a frenzy, his balls touching her ass as she came up, his cock going so deliciously deep.

She wanted to say things to him, whisper hot words in his ear, but although she was feeling an intense rapture, she could only moan and cry out softly as his cock thrust in and out of her cunt.

She closed her thighs against his, scissoring them open and closed, her hands holding each cheek of her son's pumping ass, her fingers resting at the split, almost between them.

"Ooooooh…" she purred.

"Mmmmm!" Jerry gurgled.

His cook came up and down slowly, fucking in and out of his mother's cunt completely, from swollen head to base. He never pulled his cock all the way out of her pussy, but just before the cock-head came free, he pushed back into it, so slow Marcy wondered if she would go out of her mind. The powerful urge to slam her cunt up and down hard and fast on his cock was very hard to resist. She wanted to fuck him frantically, increase the friction of his throbbing hard-on against the fiery tight walls and lips of her juicy cunt.

"Ahhhh!" Marcy moaned.

"Oooommm!" her son responded.
