The ‘Sir’ came out without thinking, he could tell, so he didn’t rebuke her for it. At this point, being a submissive as long as she had been, it was ingrained in her to call her Dom ‘Sir’, and it was actually a good indicator for him of where she was in her head during a scene. Once she started calling him Sir, he knew she wasn’t really focused on what she should or shouldn’t be calling him... she was just running on instincts.

Moving back around the desk, Michael admired his handiwork on the areas he’d just flogged. The rosiness of her skin was nicely spread over the entire area he’d flogged, bringing all the blood to the surface of her skin and making her much more sensitive than she would normally be. This was going to hurt.

Grinning, he widened his stance slightly to keep his balance as he set himself just to the side of her, grabbed his throbbing cock with his left hand, and drew back his right arm, holding the folded over strap tightly.

WHAP!

She jerked with a scream, followed by another high cry, as a nasty red welt rose up across the upper crest of her buttocks. The strap had caused her scream; her jerking and scraping her nipples across the wooden desk had caused the second cry she’d made. A double whammy for one stroke.

Giving her a moment, Michael stroked his cock as Ellie shuddered and settled back down, a hitching in her breathing letting him know her tears had started and this time she wasn’t able to slow them.

“Do you want me to stop?” he asked, although he was fairly certain he was interpreting her cries correctly.

“No!”

The immediate response let him know he was right on target. Ellie really liked this strap.

WHAP!

The second blow landed just above the base of the plug, across the very center of her fleshy buttocks, and Ellie howled as the two-inch thick line immediately rose on her flesh, parallel to and just an inch below the first. Her body was heaving somewhat now as she writhed in reaction, apparently no longer caring how her nipples rubbed over the desk - or perhaps the pain it created distracted her from the burning line he’d just laid down... or perhaps it felt like nothing compared to the strap’s bite.

Michael stroked his cock again until she stilled, waiting and ready for the last blow.

“Last one, Ellie, and then I’m going to fuck you.”

“Yes, Sir.” Despite her obvious tears, she sounded breathy, eager. Needy.

He flicked his wrist.

WHAP!

Right across her sit spot.
