She'd already greased her whole in the bathroom, and now she rose up and turned her back to him to kneel on the bed with her ass in the air.

"Slowly," she said. "If you don't go easy I'll make you stop."

The boy trembled with excitement as she raised her ass in front of him. He gazed at her greased asshole with hot eyes, at the fine dark hairs pawing round her puckered shitter. He'd fucked ass before and he knew the pleasure he would have. Craning his neck to the side to look at her, he thrilled at the way her tits hung down off her chest.

"You're so beautiful, Gayle." "I'm crazy to let you do this." "No you're not."

"Are you sure you've done it before?"

"Wait and see."

And then she moaned as he placed his knob against her asshole and pushed forward.

"Easy, Scott."

"Relax!"

"Just go easy!"

She opened for him, feeling his cockhead push in, thankful that it wasn't as bad as she'd feared. Just a little pain in the stretching. This was certainly the biggest cock to ever go in there, like a huge log slowly pushing up her shitter and reaming out her insides.

"Christ, it's good," he said.

"Are you all the way in?"

"Just a little bit more."

And then she felt his balls against her cunt and she knew she had every inch of him, every inch of that big click spearing her ass and driving her crazy with pleasure.

Outside on the terrace, Linda's heart threatened to pound its way out of her chest as she secretly watched them.

Part of her mind blazed with excitement, but another part of her mind gazed at them with a crazy detachment.

Her stepmother and her brother.

She could see Scott's balls swinging back and forth as he slowly fucked Gayle's ass.

She could see the way his thick cockshaft stretched Gayle's asshole into a huge round mouth.
