Slowly Lisa drew in more and more of his cock. She felt her cheeks puffing out as she tried to keep her teeth from scraping the throbbing sides of his dick. At the same time the blonde nurse stroked Chad's fuck-sacs. She knew she was exciting him terribly. But the big, hot man somehow managed to avoid coming as Lisa sucked and sucked.

Finally she managed to engulf all of that steel-hard shaft. With a little difficulty, Lisa stroked the sides and sensitive bottom of Chad's prick, paying special attention to that throbbing blue vein. Chad groaned, clutching at Lisa's long blonde hair, forcing her mouth against his hot groin. He rotated his hips around and around, churning his cock inside her mouth and nearly gagging Lisa as he felt himself roaring to a climax.

"Suck it, suck it," he whispered, tilting his head back and fucking Lisa's mouth as his fingers dug into her hair. He was going out of control. His thighs slapped against the woman's lips and nose, his balls swinging forward and slapping her chin as his dick rammed faster and harder down her throat.

Lisa excited the doctor more by moving her fingers under Chad's balls and up his hairy ass until they found his puckered asshole. As Lisa kept sucking away at his ramming dick, she slid her forefinger into the tight hole. Chad gasped but didn't protest as the finger shoved deeper into his shithole.

Lisa could feel his prick starting to leak pre-cum juices more freely now. His cock was throbbing more rhythmically, and his breathing was becoming irregular. Lisa enjoyed this kind of power she had over the doctor. But at the same time, she didn't want him to shoot off in her mouth. She was giving him a great deal of pleasure now. But her cunt was completely unattended. She needed Chad's big cock sliding deep into her pussy.

"Please, don't come like that," Lisa gasped as she pulled her head from Chad's bobbing prick. Chad gasped out loud, fighting down the desire to blow his load into the air.
