"I wish I knew what to do!" Karen exclaimed.
Suddenly, her mind was filled with an encyclopedic knowledge of sexual activities. Images of what she could do to Jon flashed through her mind. Deciding quickly, Karen went to Jon's door, and peeked outside. The coast was clear, and she dashed down the hall into Jon's parents' room. She opened the drawer of their bedside table and grabbed the bottle of lubricant which she, magically, knew would be there. She dashed back into Jon's room, where Jon stood holding his enormous, flaccid member, looking shocked and confused.
He didn't have long before he felt even more shocked. Karen dropped the bedsheet that was wrapped around her, tore off Jon's tee shirt, and popped open the bottle of lubricant. She drizzled it over her large breasts, and all over Jon's huge cock. Then she began to use a dizzying array of erotic techniques to stimulate Jon, as she guided him onto the bed.
Within moments, Jon's huge penis had risen to full attention, and it stood over two feet long. There was so much blood pumping into it that it left Jon feeling light-headed and dizzy; he couldn't think straight, partly due to the decreased blood supply to his brain, but mostly due to the perverse and erotic things that Karen was doing to his body. If it didn't feel so good, he would have felt violated - Karen was prodding and massaging his body in places that he didn't know he had.
Karen spent the better part of an hour slowly bringing Jon to a mind-numbing climax, carefully making sure that he was on the brink of complete ecstasy for as long as possible. She slid up and down his giant penis and all over his body, moaning as he cried out from the erotic stimulation. Finally, Jon had the most spectacular, cathartic orgasm of his entire life. His huge cock sprayed cum all over himself, Karen, the bed, and the ceiling - there must have been a quart of the stuff.
Licking her lips, Karen rose from the bed where Jon lay, completely spent. His penis pointed stiffly into the air, softening very slowly. She was covered in a sticky mixture of lubricant and ejaculate, which dribbled down her breasts and thighs. She picked up the stone from where it had fallen on the floor and dropped it in Jon's hand. Then she said "I guess I should go clean up."
Karen turned and stepped out of Jon's bedroom, sauntering down to the bathroom completely naked...
