"Yeah, but well, I don't want to get caught by your parents!" Mark exclaimed. "They could walk in here and see you sucking me off! I'd get in a lot of trouble!"

"Oh, Mark, who give a shit?" Lisa replied. "They won't be home for hours, and besides, who cares if they catch us? Awwww, honey, my cunt's so wet it's huffing me! Just let me feel your big cock, Mark! I want to suck it so bad and drink down your cum!"

Groaning hotly, Lisa placed her palm over the boy's throbbing stiff rod. Mark looked worried. He made a vague effort to step away from her. But it was obvious the touch of her fingers on his hard meat excited him. His blue-veined cock grew another inch, until Lisa could actually see the bulbous, cum-dripping head poking out under the hem of his shorts.

That was more than Lisa could stand. The sight of her boyfriend's pulsing cock, the thick white jism burbling out of its bloated knob, made her tight little cunt as hot as a furnace. Whimpering, she leaned forward and firmly gripped the waist of his shorts in both hands. Then she pulled them down to his ankles, shamelessly revealing every inch of his lean teenage body.

"No, Lisa," Mark murmured. "I mean it, you better not go any farther. We're gonna get in trouble!"

"Oh, Mark, oh, my God, look at your cock!" Lisa gasped.

A smile spread across the teenage face, and her throat ached with the need for her boyfriend's hot meat pulsing between her legs. Mark had the most beautiful cock she'd ever imagined. It was at least eight inches long and very thick, standing out of the curly bed of his cock-hair with the stiffness of a steel rod. She could see the blue veins running up its hard pink surface, and the swollen bulb of its purple cockhead. Half the length of his burning stick was covered with the thick jism that burbled hotly from his cock's slit.

"Oh, Jesus," Lisa sighed. Licking her lips, the horny teenager wrapped her fingers tightly around the meaty thickness of Mark's cock, squeezing his burning cock flesh against her palms. "Your cock is so wonderful, honey. Look how heavy your balls are! I can hardly wait to see you cum. I'll bet you'll shoot off in buckets!"
