"Bob, no!" she cried. "I won't fuck you before we're married."

Bob's patience gave out completely. Before Lisa could stop him he straddled her chest, his knees pinning her arms, his hugely swollen cock wagging an inch from her face. "Okay, bitch," he snarled, "If you won't fuck it, eat it!"

The next thing Lisa knew, he was shoving his thick steely prick into her mouth. His big throbbing cock stuffed her mouth completely and stretched her lips almost to bursting. She was scared, but she realized she had damn well better bring him off this way or risk getting raped. She started to suck hard and fast on his fat throbbing cock, and Bob shivered with pleasure.

"That's it, baby, suck!" he groaned.

Lisa had never even seen a cock before, let alone sucked one, but she started getting off on it very fast. She loved the sensation of sucking his hard slick prick, loved the salty taste of his oozing prick juice. Hot saliva rushed to her mouth and bathed his cock. As her excitement grew, she sucked him harder and faster, making a lewd slurping noise.

"Mmmmmmmm," she moaned.

"You like the taste of my cock, don't you, bitch?" Bob said, leering down at her. "Well, you're gonna get a whole mouthful real quick."

Lisa met his eyes, hers hot and glowing. Her cheeks were drawn in sharply, her tongue raised, sheathing his cock in scorching wet flesh. She sucked ravenously on his prick, stretching and squeezing the hot meat, sucking the juice right out of his pisshole and swallowing it with a greedy gurgle. Bob realized the girl was a natural born cocksucker, hungry for his cock.

"Yeah, that's it, baby, suck my cock good and hard," he moaned.

Lisa felt her cunt creaming uncontrollably as she blew him. She could hardly believe how aroused she was getting from sucking on his prick and eating his thick steaming cum. She used powerful vacuum pressure to draw his thick hard-on even deeper into her mouth, till the big bulbous head of his prick was butting the back of her throat and his swollen bristly-haired balls were rubbing her chin.
