Not in the slightest

Sam looked down at Ellie.... virtually naked, hunched over on the knees, her face and hair soaked in cum and her lips wrapped around his tormentor's dick. This wasn't the step sister he'd known these years. He watched as John slowly removed his cock from her mouth.

"You know guys normally ask before they shoot their load over my face" she scowled at him.

"Yeah, well where's the fun of giving you warning about what's coming next" he grunted back at her

Ellie smiled as she grabbed her top and used it to mop the spunk from her face. "Do you always come this much?"

"Only for girls I really like. You should take it as a compliment"

"Ha! Right, you go and wait in my bed. I'm going to have to shower, after which you're going to fuck my pussy like you've just fucked my mouth"

As soon as Sam realised they were about to relocate upstairs he retreated stealthily back to his bedroom. Whilst he wanted to avoid John at all costs, he knew that if Ellie knew what he'd just witnessed she'd never be able to look him in the eye again.

Twenty minutes later the thudding started. If last night was loud enough to wake him then tonight the sound of Ellie's bed knocking against the wall would be keeping the entire street awake. And mixed in was Ellie's pleas for John to fuck her harder, faster, deeper....

Aroused, yet horrified, Sam knew he couldn't leave the house now in case he was caught. Tears formed in his eyes as he stroked his dick to the sound of the most attractive woman he'd ever known gratefully being pounded by the man who had bullied him and made his high school life a nightmare. And now he'd found a newer and worse way to torment him.

Ten minutes later Ellie screamed John's name as she orgasmed. The first of many over the course of the night.

Sam knew he couldn't bear this any longer. Tomorrow, one way or another, he was going to make sure whatever was going on between Ellie and John ended.
