"No," she sighed, "you shouldn't."

His teeth clamped down, gently but insistently, upon the stiffness of her nipple, and at the same moment his finger eased a little deeper into Mary Jo's pussy. The girl gasped and groaned, and she felt a shudder convulse her snug cunt, an ooze of fluid leaking out around Zack's probing fingertip.

"I've been watching you," he whispered, unhooking the snap between her tits and pushing the bra way. "Watching you grow up, wondering what it would be like to be the first man to get inside your sweet pussy. Am I the first man inside you, Mary Jo? Is my finger the first one you've ever had up your cunt, besides your own?"

She nodded. "It… it shouldn't be there," she said softly, but she made no move to push his hand away.

"Lovely tits," Zack said. "Small, but firm, and capped with the sweetest, pinkest nipples I've ever seen. Has anyone ever kissed your tits like I just did? Ever sucked on them like I'm going to do, Mary Jo?"

Mary Jo shook her head. "No, no, nobody."

He probed inside her cunt with his finger, scratching a ticklish and insistent pattern into her heated flesh, while he feasted on her tits.

Mary Jo couldn't believe how fantastic it felt to have his mouth on her tits. The way her nipples throbbed and pulsated as he lapped them, as his lips pulled on them, making them stiffer, longer, sucking hard as the pink extension grew and grew and grew.

Her entire body was hot, and the heat was centered in her cunt, where his finger continued to work softly, delicately, but insistently, in and out, in and out…

"Let's get you out of these things."

Mary Jo was hardly aware of his words, but she could feel her skirt being taken down her long slim legs, her panties being pulled down too. When he set her onto the sofa again, her ass was bare and she could feel the plush surface of the upholstering against her naked bottom.
