Just as it had done when Susan, Jerry's stepmother, had stroked her, Marcy's cunt was turning very juicy, tingling, until she wanted to scream with the sensational feelings. She knew that by not resisting, not protesting, she was giving her son consent to fondle her titties. She knew that Jerry knew, too. On one hand she wanted desperately to stop him now, but on the other hand she wanted him to keep doing it. He was rubbing his cock up and down against her now, not trying to conceal his desires. He was humping at her hip as if fucking her, and Marcy found she was starting to squirm, to writhe and keep the contact of his cock against her.

It was a moment before she understood Jerry was no longer fondling her tits. Her eyes had closed as the steamy pleasure came over her, and she had been panting softly. She felt her son's fingers sneaking into her gown, and again she was holding her breath. She felt his finger carefully touching her bare tit, scraping over her nipple.

The orgasm was fast, before she knew it was going to happen. Suddenly as her son touched her naked nipple, Marcy came. It happened so fast she gushed, unable to stop the sound, and her hips jerked. She turned her head away from him, toward the wall, purring. Her arm tightened about his shoulders. Jerry apparently took the reflexive squeeze of her arm as permission.

He pulled her gown away from her tit and placed his mouth on her nipple, and started sucking at it, pushing his throbbing cock against her hip without trying to be subtle about it now. He was fucking at her body, sucking on her nipple with his hot, wet mouth, his tongue flicking eagerly. She heard her son making moaning sounds of hot pleasure, and her arm squeezed him down onto her tit. She felt she should say something, anything, but her voice refused to work. She gurgled softly, but no words came out. Her fist opened, and she began to shove the sheet down her body. When it was at her hips, she lifted her gown and moved her hand through the silky curls of her cunt. The sheet hid her pussy as she moved a finger to her clit. She couldn't believe how hard it was, how sensitive, how tingling it had become.
