She starts with her hand.

With a trembling hand, she took it out of her hands, and slowly, slowly, moved it towards a flopped thing that was coming out of Dave's zip. She touched it slightly with her fingers, feeling the softness of that skin, and then grabbed it in her hand. It was soft and squishy, like some kind of worm. It didn't look at all like those pictures in the biology lessons...

"You want me to fall asleep? Move your hand, squish it!" he proclaimed loudly, making Berry flinch. She looked at it. It was small, smaller than even her hand, with some slightly visible veins going through its entire length. It looked weirdly.

Berry held it a little tighter and began to move her hand in a random direction. Does that make him feel... good?

"No, you slut, up and down, slowly. Or fast, if you want to end it quickly on your face."

"End quickly on my... face?" Berry's thoughts were muffled, and yet she began to move her hand up and down, holding the small, wiggly worm... soon enough, she felt it began to... throb. Like a heart beat. She felt her hold weaken, as the thing inside her hand became larger, bigger, and more and more lively, as it began to throb stronger and stronger... quickly, it became significantly bigger than her hand. With an ugly, red head on the tip of his... thing, with a little hole inside. Is this where the boys piss? Is this the hole where it will... release?

"Good... good..." Dave said, and Berry could swear his words became a little softer. Was he enjoying it? Her, doing those weird up and down movements with her... hand? There were doing such... lewd thing... behind the school. Her moves had to become even stronger, and her grip even tighter, and Berry felt tired after some moments. So tired, that she began to breathe heavily, looking at the throbbing thing in her hand.
