Bully's Ultimate Torment

Thud. Thud. Thud.

Sam's eyes slowly adjusted to the dark and he checked his clock. Three thirty am. He wasn't sure if it was the knocking sound or his full bladder that had caused him to wake up, but he knew that unless he at least went for a piss he wouldn't be getting back to sleep anytime soon. Carefully he got out of his bed and navigated his bedroom.

Thud. Thud. Thud.

The knocking noise was louder in the hallway. He walked towards the bathroom and noticed his step sister's bedroom door was ajar. As he passed by he couldn't help but look in and his eyes were met by a sight he would never forget.

For the past five years, since their parents had got together, Sam had been obsessed with Ellie. And here she was, riding a lucky guy as if her life depended on it. All these years he had spent imagining her naked and now he was getting a perfect side on view of her getting fucked. He marvelled as her perky c-cup breasts rose and fell gloriously as she bounced away enthusiastically.

Sam felt his dick harden in his boxers. He knew it wasn't right to be watching this, but he couldn't tear his eyes away.

"Oh fuck.... that feels so fucking good" she groaned as her head rolled back and her long blond hair fell down her back.

Sam wondered if he'd ever heard Ellie swear before. His hand instinctively slipped inside his boxers to play with his bulging erection. A voice in the back of his mind told him that it was one thing to watch his step sister having sex, another thing altogether to jerk off to her. But this voice was quickly ignored as he pulled his dick out and started pleasuring himself to the sight of his step sister fucking.

"Your massive cock feels so good inside my tight pussy"

How good would it feel for Sam to have his dick inside her. Oh god he'd make her moan.

"Oh yes, just like that, just fucking like that"

Sam was mesmerised by the sight of his step sister's gorgeous body. All these years of frustration, trying in vain to catch her some exposed flesh, and now he was getting to see it all. Such perfect breasts, such a toned stomach, such gorgeous legs, the sexiest of moans everytime she slid down on the cock... his hand was a blur as he tried to find some release.

"I want to feel you fill me with your hot cum"

This final line was too much for Sam, he raised his left hand just in time to catch his load as it erupted out of his rock hard dick. He breathed heavily as the guilt of what he'd done took hold. He took one final glimpse at his sister - Sam was relieved she hadn't noticed what he'd been upto, before quietly shuffling back to his bedroom.
