"No, Lisa," Mark gasped. He winced with the pressure of her hands around his throbbing cock and leaned away from her. "Don't do this. You'll just get us in a lot of trouble."

But Mark's please no longer carried much conviction. Lisa knew how much the squeezing touch of her hands on his cock had excited him. She could feel the furious throbbing of his burning meat against her hands, the way his hot cream dripped all over her fingers. Giggling, she pushed her hands down the swollen stalk until four inches of his cock protruded body from the grip of her fists. Then she frantically began to lick hungry circles around his purplish cockhead, hungrily drinking up the thick, delicious juices that burbled up his cock from his tightened nuts.

"Oh, God!" Mark gasped. He bit his lip hard and closed his eyes, obviously giving himself up to his horny girlfriend's sucking. "No, Lisa… unghhh… you better… better stop… nooooo…"

"It tastes good, Mark," Lisa burbled. "Your cock's oozing so much cream, and I love the way it tastes. I want to suck your cock now! I want to suck your cock!"

Lisa continued to lick up her boyfriend's hotly dripping cum a moment longer, devoting the attention of her wet mouth's sucking to the shiny skinned crown of his cock. Then she opened her mouth wide and immediately began to suck his enormous rod as hard as she could. Her lips tightened in a wet circle around the blue-veined flesh of his cock. Her cheeks caved in as she increased the suction in her throat as much as possible. Mark lifted his hips, thrusting another inch of his huge cock into her mouth. Lisa hungrily sucked the fat knob of her boyfriend's stiff cock. Her lips and tongue laved constantly around the mushroom-shaped head. Her hands squeezed the base of his organ and stroked the loose flesh up and down, jerking him off into her mouth.
