Michael grinned at the conundrum she was facing as he continued to flog her, taking extra care around her ass so none of the strands slid between her legs and anywhere near the clamp on her clit.

She couldn’t hold herself totally upright forever though, especially not as her shoulders and ass turned a dark sunset pink and her hips moved with each blow, getting more and more into the rhythm he’d established. The swaying movements were erotic, as she was seeking out the stimulation she needed to cum and was unable to find it. This time when her nipples dipped down to touch the desk, she whimpered but didn’t jerk back up as she braced herself on her forearms. The tips of her breasts flattened against the desk and she held herself perfectly still, trying not to move and disturb her clamped buds.

Time to switch implements.

“You said you enjoy the rubber strap, didn’t you, Ellie?” he asked, almost jovially as he gave her one last lashing across the shoulders with the flogger.

She shuddered. He thought he heard her whisper ‘oh god’, but he wasn’t completely sure.

Laying the flogger on the desk beside her, he moved around to his toy bag to pull out his new strap. Her face was flushed, eyes glassy and anxious, lips swollen as she watched him. Her eyes widened when she saw the narrow strip of rubber. Only two inches wide, he had practiced wielding it quite a bit this week, knowing it had a seriously nasty bite and not wanting to push her past her limits.

“Three strokes with the strap,” he told her, and could almost hear the war going on inside of her head.

Part of her wanted to insist she could take more than three strokes of any implement; another part of her was wary of the thinness of the strap and the fact that she hadn’t actually felt its impact yet. Not to mention he’d just flogged her ass to a nice, sensitive, rosy hue and she didn’t know how hard he planned on wielding the strap. In the end, she just stayed quiet, her anxiety and desire for more easy to read in her adorably conflicting expressions. Michael just grinned.

He’d start with three. He doubted she’d need more. Or if she could even tolerate more. He was certainly starting to grow impatient. His cock was starting to ache with the need to be inside her, and when she finally looked away from the strap, her eyes went immediately to his dick. She licked her plump lips as she stared at his erection, which didn’t help him control his arousal at all.

“What color are you, beautiful?” he asked, folding the strap in half and tapping it against his thigh, which drew her attention away from his cock.

She whined, high in her throat. “Green, Sir.”
