Billy sat up and gazed at her heaving tits. His heart pounded with excitement. None of the girls he'd fucked were as pretty as his sister. And none of them were built like Susie. Her nipples were like two pink cherries and her ass was round and firm and full. How lucky could a guy get?

He continued staring at her and Susie grew impatient. "Come on, I'll do it!" she snapped. She straddled him and reached down to grasp his dick in her fist.

Billy lay perfectly still while his blonde sister stuffed his dick into her snatch. When it was inside the hot grip of her cunt, she leaned over, her tits over his chest. And she kissed him on the lips.

They frenched. The teenage boy had never been kissed this way. Susie explored his mouth with her tongue while she pumped her hips and fucked him.

He held her tightly as his dick slipped in and out of her cunt. She wiggled her ass from side to side, making wild and wonderful sensations course through his crotch.

"You sure you've done this before?" she whispered.

"Yeah, why?"

"You don't seem to know what you're doing."

"Jesus, give a guy a chance!" he croaked, arching his back and pumping his ass off the bed.

"That's better!" she hissed. "Now you're catching on!"

They bounced around wildly. Susie sat up and closed her eyes as she sank up and down on his dick. Her tits jiggled and wobbled and Billy reached forward and grabbed once flying tit in his hand.

She fucked him faster. She gripped his dick with her tight pussy and brought her tits over his face. "Suck!" she hissed. "Suck me while I come!"

He nuzzled her nipples between his lips and kneaded her flesh with trembling fingers. She rocked in a frenzy and perspiration dripped down both their hot young bodies.

When she climaxed, she shuddered and shouted and babbled out loud. He squeezed her tits as she clutched his fuckpole inside her spasming pussy.
