"Remember when we used to wrestle until we always ended up breaking something?" she gasped, grabbing at his hand.

"Yeah. Dad would raise hell." Steve wiggled his fingers up under her arm and Robin screeched with agonizing joy. Stevie always could tickle the shit out of her, tickle her until she couldn't breathe, tickle her until she almost passed out.

Steve got a leg out from under the covers and caught one of her thighs in a scissor hold. Robin felt her shorts pull up between the lips of her cunt. It felt funny and her tits were being rubbed too hard again. Her breath came in panting little gasps. Then she realized that her brother had nothing on but a T-shirt.

Steve pushed her down by the wrists and pinned her easily. She snapped her teeth at him and grinned. They were both breathing hard. She arched her back and fought to bounce him off her, but couldn't. She felt happy, wrestling just like they'd done so many times growing up. But there was something different too. Something very, very strange about the room, about Steve… about the way his warm, naked thighs felt pressing between hers.

"What is that funny smell, Stevie?"

"You can't get up, can you?" he whispered, blue eyes daring her.

She started to struggle again, working her hips, trying to slide them to one side. She couldn't close her thighs because her brother had wedged his down between them. It felt so… unfamiliar. They'd wrestled before. But the rub of Steve's chest against her titties was making her breathe strangely.

Those damned tits, why were they getting in the way! And there was a tingly sensation in her cunt. Every time she tried to work her pelvis so she could slide out from under Steve's body, her shorts pulled tighter into her crack. And there was something else pushing there too. It was Steve. It was Steve's cock!
