"Come over here and grab me. I'll tell you how to."

"Doug! If Mom and Dad knew what you'd just asked me to do, they…"

"Hey, they don't know." Her brother motioned with his hand. "Come on. You want the money, don't you?"

Yes, Robyn wanted the five dollars very badly and this seemed like the only way she was going to get it. She went over to where her brother lay on the bed. Under her nightie, her cunt was throbbing in the weirdest way. She was breathing hard too. She put a hand out, almost closing her eyes as her brother moved so she could touch his cock.

"It's so hot!" she gasped, tingling as she put her fingers around it. She squeezed, letting the baby oil squirt between her fingers. Doug had the strangest look on his face. His eyes closed and he moved his ass round on the bed real slow. This excited Robyn more than she thought it would.

"Go on, move it."

"How? Like this?" Robyn let her hand slide over her brother's cock head. The spongy flesh gave as her thumb and finger slipped over it, but it was surprisingly firm underneath. Robyn had never touched a man's cock before in her whole life. She couldn't help but think how it would feel to have her cunt speared by something like she was holding. The fact that it was her brother's cock she was fantasizing about made her blush.

"Do it faster, Sis," Doug groaned, moving his hips even faster. He was panting now. Robyn moved her hand up and down with a quick rhythm. The oil trickled down her wrist. The sound of her lubricated fingers sliding over her brother's greasy cock made her tremble. But it was the feel of him that was most exciting of all. He was so damned hard! His cock jerked in her grip. When she smoothed her soft fingers down over his cock-tip, Doug shuddered and arched his back.

"Jesus, that's the way, Sis! Qhhhhh, yeah!"

"You'll give me five dollars for doing this?" she asked, thinking it was all a bit too easy.
