He'd grown weary of pretending to struggle, in case she was watching. This was new, being unable to see and lashed to the bed. An hour now, maybe more, and his anticipation had gone soft; replaced by vague unease and just a hint of apprehension. Sound, unfamiliar, startled. Heels perhaps, creaking wood, and unfamiliar leather. His nostrils flared at the scent of strange perfume. His wife had never done anything this elaborate since they started exploring her switch side.
Alone again, time to adjust to the silent room and ponder if this was punishment for some unknown slight. Nearly asleep, time meaningless his lips awoke to her familiar kiss, fleeting but reassuring and erasing fear. A noise from above, the stretch of leather, creak of it binding under load unnerving to the unaccustomed ear. Rope sang softly against itself; some kind of pulley, impossible to know. Involuntarily, he steeled for pain. She had surprised him before.
This was different. Without warning wet heat settled on him and the surprise of it engorged him immediately. He bucked upward unthinking, forgetting his role. But it was gone, the sweet sensation now replaced only with perfume. Rope on rope rasped gently, he understood now as she lowered down on to him by unknown apparatus. Feeling nothing but her pussy, no skin or hair or fingertips was maddening after the time deprived. But he was determined to perform, and held still resisting the urge to thrust up to his wife above him.
