Robin's tongue snaked out, lightly flicking the tip of his prick. The faint taste of his cock wasn't anything like she'd expected. Excited by the strangely erotic taste, she began moving her wet tongue around and over the entire surface of his rubbery-hard knob of male meat. It was exciting to slide her wet tongue over the rough goose-bumps that were standing up on his lust-bloated glans. Gaining confidence with every passing second, Robin opened her mouth and slid her juicy lips down over his slippery cockhead.
"That's the way, honey!" Mark panted, feeling his hard knob slithering into the moist warmth of her mouth.
"Does it really feel good?" she whispered, momentarily removing her lips from his prick.
"Shit, yes!" he gasped. "Keep suckin'!"
Robin once more lowered her mouth down over the swollen head of his super-hard rod. Having no knowledge of cock-sucking, Robin had jacked him off enough times to know what excited him. She began bobbing her head up and down, actually masturbating him with her mouth, and from the way he was lurching and jerking, Robin was almost certain that she was doing it right. The inexperienced girl was getting more excited with every passing second. The feel of his thick, hard cock slithering over her tongue was almost blowing the blonde's mind. She began taking more and more of his shaft into her mouth with every noisy slurp and was loving every inch of it. She loved the way his big cock filled her mouth as it nudged at the backs of her throat and pressed out against her cheeks. Tangy drops of seminal fluid oozed out from the tip of his knob and onto her tongue. It was a new, mind-blowing experience to the excited young girl, having never dreamed that sucking a cock could be such a fantastic thrill.
