For just a moment she hesitated, then smiled at her son. "We can do it again tonight and every night, if you'd like," she said, her voice low and throaty.

Jack sat up suddenly, his eyes gleaming. "Hey, that's great, Mom! Let's do it right now!"

Her eyes drifted to the front of his pants and she detected the growing lump of his cock. She smiled at him and licked her lips with slight nervousness. Although Jack was as eager as any young boy could be, she still knew she had to take the initiative.

Marian lifted her hands and began unbuttoning her shirt. She had gone without her bra for the first time in her life and when the shirt was unbuttoned, her arching tits swelled out succulently, pink with dark nipples. Marian had never been the aggressor in her life and she wasn't quite sure how to go about it. But the excitement in her son's eyes as he gazed at her tits encouraged her. Feeling shy, she lifted her hands and cupped her tits.

"Why don't you come over here and feel them, Jack?" she whispered.

When he got to his feet, her eyes stared glassily at the place where his cock bulged inside his pants. When he stood at her side, his hands cupping and molding one of her tits, she ran her hand out and closed it over the lump of his cock. She squeezed it and made her son moan happily.

"Suck it, honey," she whispered huskily. "Suck on my nipples, Jack!"

He leaned down and closed his lips about his mother's hard, rubbery nipple. His mouth was hot and wet as his tongue flicked over her nipple. He molded her naked tit with both hands, making her nipple jut out and into his mouth. Marian cupped her hand into her son's crotch, pressing at the throbbing hardness of his cock and balls. She felt him shaking as she brought her other hand up to hold his head down tight into her tit.

Then she began unzipping his fly. Once it was open, she snaked her hot hand into his pants and closed it about his hard-on. Pulling her son's cock from his pants, she closed her hand around it tightly and began to pump back and forth. Jack moaned around her nipple, sucking harder.
