Jenny pushed her lips against her boyfriend's and opened her mouth. Her tongue snaked out and flicked over Jack's lips just as his tongue was coming out to meet hers. Their tongues met and began licking each other, softly pushing and nudging. Their heads turned from side to side, lips wetly sliding and tongues working. Still, Jenny jerked him off.

Loving the velvet heat of the boy's cock, Jenny pulled and stroked it. Her hand slid to his prick base and she encircled it. She pulled his loose cockflesh in short strokes, squeezing and massaging. Then her hand slipped up to the middle and began lightly rubbing. Softly slipping up to his swollen cock crown, the girl's fingers began twisting and turning and kneading his reddened prickflesh. Her fingers traced around his big pisshole. The little bit of slippery wetness seeping from his piss-slit was picked up and smeared around. Jack groaned into Jenny's mouth as his fluids made the girl's fingers slip and slide over his cockhead. His cock pulsed harder, and his tongue began working more frantically.

Feeling like her tongue and lips were being sucked into Jack's mouth, Jenny expertly massaged his cock. Her hand squeezed its way back to the thick base and to his balls. Gently, she tickled the boy's ball-sac. Her fingers went under his balls and hefted them. She rolled them in her hand as she felt their weight. Then her hand flicked back to the base and squeezed and stroked once again.

She broke off the kiss to focus all her attention on the cock in her hand. She stared intently, pumping in long, slow strokes, from the base to the tip. With the other hand, she felt his balls and began playing with them at the same time. As the boy's cock swelled even bigger and harder, Jenny's eyes shined with excitement. She loved seeing what she could do to a cock. From the way this one was swelling, she knew it would not be long before the boy spurted his cum into her hand.
