Jack braced himself by placing his hands on each side of his mother's shoulders. Then he began to thrust his cock in and out of her cunt. They gazed into each other's glassy, smoldering eyes. Marian dug her fingers into the sheet as her hips began to move up and down, meeting her son's hard cock.

She felt his hips-sliding along the hotness of her inner thighs, sending sparks of delight through her naked body. Her breathing increased until she was softly gasping with ecstasy, her hips bouncing up and down in slow motion as he drove his cock into her. The way his balls slapped against her naked ass cheeks increased the pleasure that brought a flush to her flesh.

Her fingers clawed at the sheet and the desire to wrap her arms around him and pull him close, to crush her tits against his chest, was very strong. Still, she resisted the outward display of what she was feeling. She knew a man – or in this case, a boy – with a hard cock seldom suffered any shame, until the fuck was over. She didn't want her son to have any feelings of guilt, so she lay still with only her hips pumping to his, gasping softly and gazing up into his face.

Marian had always been a sensual woman. She almost always came when her husband fucked her. Now, however, she felt herself going through a series of warm, almost gentle, orgasms. She was surprised at this. She had heard of women who enjoyed multiple orgasms and had felt cheated. But now she felt them and each one was stronger than the preceding one. She could feel the throbbing hardness of her son's cock as it slid along the wet sensitive lips of her cunt and scraped her clitoris.

Jack grunted as he plunged his cock into his mother's slippery cunt. His pumping hips bounced up and down faster. Marian detected a further swelling of his cock and she could feel it jerking deep inside her pussy. She had felt that same sensation with her husband and she knew her, son was about to come. She wondered, vaguely, her hips moving up and down with him, if he would come inside her pussy. She didn't want him to yank his prick from her cunt when he came, she wanted to feel the thick sweetness of his come juice as it squirted into her.
