"No, Lisa. Oh, Christ, oh, shit!" Mark gasped. "That's too good… I'm gonna shoot off… don't suck it so hard or I'll cum! Oh, God oh, God!"

Lisa was much too busy with the pleasures of cock sucking to make any response. Already she loved the taste of her boyfriend's thick rod in her mouth, and her stomach ached for the molten load of his gushing cream. Wantonly she sucked his cock harder and harder, making the rock-hard shaft pulse between her lips with the intensity of the blow job.

"No, Lisa, no," Mark groaned. "I'm gonna pop my rocks… oh, slit, stop sucking so hard… I'm gonna cum… oh, shit… so fucking good…"

"Go ahead and cum, Mark," Lisa whispered hotly. She removed the juice-soaked knob of his cock from her lips, whispering the words wetly around its shiny crown. "Cum all over me if you want to, all over my face. I want to drink your jism, lover. Your cock is so big and good!"

Mark could say nothing in reply. He stood before her with his cock throbbing against her cheek, his meat growing longer and harder by the second as the heat surged into its already engorged length. Lisa giggled and again returned her hungrily sucking mouth to his cock. This time she sucked his cock as expertly as she knew how. Her head bobbed up and down over his cock as she fucked herself in the mouth with his swollen rod, waiting eagerly for the drenching spasms of his shooting cum.

"I'm cumming, Lisa," Mark sighed. "Your sucking so good… oh, fuck… I can feel it in my balls… I'm cumming now… awwnngh, shit, I'm cumming!"

For a moment Mark's cock bloated to absolute stiffness between Lisa's pursed lips, and she saw his balls tighten. Then his nuts frantically began to unload their wad deep down Lisa's clinging throat. The thick white jism squirted explosively from his raw-skinned cockhead, gushing in a torrent of cum into the horny girl's sucking mouth.
