"Then get down on the floor."

She felt her knees give out under her as she sank down onto the bath mat. She spread her legs and for a moment Billy gazed down at her pussy.

She wore a short skirt and no panties and her pussy aroma was strong in the small bathroom. Billy struggled to breathe as he hovered over her. The pink lips of her cunt winked open in invitation. The light sprinkling of dark hair made him groan with raw desire.

He'd seen a few pussies in magazines and one of his girlfriends once showed him her cunt. But his balls ached as he moved down over his sister to touch the vulnerable-looking slit between her legs.

As he touched her cunt she reached for his cock. Her eyes were wild and glittering. She wanted his cock inside her breaking her cherry and bringing her off.

"Hurry!" she said. "I'm so hot!" The floor was like marble on her back, but it didn't matter. All that mattered was having his prick inside her.

The boy muttered as he fell over her. His cock wedged between her round thighs, missing her cunt, but hitting her hairy mound.

"Stick it in," he said.

"I can't, you stick it in!"

"What if I hurt you?"

"You won't hurt me."

"But your cherry."

"Will it hurt?"

"I think so."

"Oh, God, I don't know…"

She tried closing her legs, but it was too late. Billy held his prick against her cunt and tried pushing in.

"Let me stick it in," he said.

"Can you do it?"

"Yeah, if you stop wiggling around."

She lay perfectly still. "I'm not moving," she said.

He pushed forward. Her cunt felt hot and wet on his cockhead. He shut his eyes and grimaced. Just the feel of her gash on his cockhead made him want to let go and come.

"Don't hurt me," she said.
