Yes he wants to see what she's up to

Carefully Sam inched forward to see what sight would greet him. He wasn't disappointed.

Ellie lay on her back, her breasts pointing skywards. But she wasn't asleep. Her hips were spread wide with her partner's head buried between her legs, her face contorted in pleasure.

"Oh yes, oh fucking yes" she moaned

Whatever Ellie was having done to her she clearly was enjoying it. Sam's dick grew hard as he watched his step sister being eaten out.

"Oh yes... just just like that..."

Ellie reached across with her left hand and started massaging her breasts, running her fingers against her stiff nipples.

"Oh god I'm going to...."

Ellie threw her head to her side and buried it in her pillow, her body visibly shaking as she came. She lay panting as the remnants of her orgasm ran through her.

Sam glanced at his watch. He was already going to be late for work, but he had a feeling the show wasn't over here.
