Mason stared at the girl securely harnessed to the four poster bed. She stood spread-eagled, her body quivering under his invisible scrutiny. He’d always loved Lexi’s body: it was a gymnast’s body, supple and lithe and strong.

His cock ached to be inside her, ached for the friction of her tight, wet pussy. But he knew he had to hold out, just this once. Lexi deserved an evening’s — hell, a whole weekend’s — pleasuring, and he was determined to give it to her. No more quickies in the back seat. No more messy, soapy shower sessions.

He wrapped his hand around his the base of his cock, his pinkie caressing his balls, and went to his knees in front of Lexi. As if sensing he’d changed position, the girl began to tremble.

Mason leaned forward and breathed over Lexi’s clit. In the swarming green light of the night-vision goggles, the folds of her sex looked like the genitalia of an alien.

“Oh, yes,” Lexi murmured.

Weird. Mason frowned up at her. “It’s: ‘Yes, Master,’,” he said. “And every time I punish you, it’s ‘Thank you, Master’. Got it, slave?”

“Yes, Master,” through the gag.

Mason breathed on her again and she writhed, her thigh muscles bunching. God, she was seriously turned on right now. He went down on Lexi at least once a week, and it usually took her a while to get going. Maybe it was the room, the ropes, the gag.

He leaned forward and kissed her hip bone. Lexi moaned and bucked her hips forward. Mason struck her ass with the switch and she groaned.

“Thank you, Sir,” came the muffled words from Lexi.

Mason grinned, tightening the grip around his cock. He’d jerked himself off minutes before Lexi had entered the room, but it hadn’t helped. He could cum right now, with a pump or two on his cock. But he wouldn’t. He would wait. He would let Lexi have a few dozen orgasms before he did.

Leaning forward, Mason brushed another kiss on her other hip bone. The girl sighed, but she didn’t buck.

“Good girl,” he murmured.

He kissed the smooth mound of flesh above her clit, touching the top of her sex. Lexi swayed a little, as if she’d taken all the weight off her legs and was simply hanging from her bonds.

Good. He liked that.

He used the tip of the switch to touch her clit, and the girl let out a gasp of pleasure that made his cock pulse in warning. Dammit, how was he supposed to keep himself in check? He peered up at Lexi, and a slow smile spread on his face. There was enough time…

“On your knees, mutt.”

The girl collapsed onto her knees in an instant. She knelt inches away from him, her blind eyes searching for him in the darkness. Perhaps she could see his silhouette, because she did eventually focus on his face.

“Master?”

But Mason ignored her, coming to his feet again. Time to let off a little steam. He pumped his cock, his hips bucking backward and forward as he moved into every thrust. Lexi, perhaps sensing what he was doing, sat up straight. She looked so expectant.

“Master!” came the muffled call through the gag.

Mason tugged free the girl’s silk gag. She opened her mouth, and he forced his dick between her lips.
