Mackenzie’s 18th birthday had finally arrived. Her neighbor couldn’t wait, so he greased up his cock, snuck into her room and marveled at her young, sleeping, naked body.

A moment later, he was straddling her tight, little ass, lining his cock up with her tiny asshole. She mumbled something into her pillow and half-woke. He took that moment to thrust in as hard and fast as he could.

Her scream filled the house as he pistoned his rock hard cock in and out of her once virgin asshole. After a few minutes, he lurched forward, pressing her face into her pillows, and his twitching cock erupted in her tight ass.

When he got up and started to leave, she turned to face him and thanked him for getting her birthday off to a great start.
