He started fondling her breasts with both hands, then moved one hand down lower to finger her. Without a head, Jenny couldn't moan, but he could feel her arch her back; it seemed that she was enjoying the sensations.
Since Jenny had been so interested in tit fucking, Jeff climbed on top of Jenny's torso and stuck his boner between Jenny's breasts. He used his hands to mash her breasts together while he moved back and forth. It felt pretty good, but the novelty of it was mostly what heightened his arousal, and he quickly reached climax. His cum would have covered Jenny's face, if she'd still had one.
Jeff took a few moments to clean up the mess, but he was still hard, and eager to fuck Jenny again. He squeezed her breasts, and licked her
nipples, but soon he was ready for the main event.
