Ippei is a single office worker who has worked hard enough to afford a luxurious home, all to realize his childhood dream of living in a harem of obedient maids. After repeated rejection on dating apps, he finally meets the sweet-looking Riena and decides she is destined to become his maid. He dresses her up, checks every erogenous zone and makes her squirt, then orders her to serve him. But the moment she licks his nipples, she makes him climax instantly. Her innocent appearance hides a sadistic woman who loves breaking strong, arrogant men. She drops the polite act, switches to teasing Kansai-dialect commands, edges him relentlessly and makes him pleasure her. Riding him like a toy, she orgasms again and again while draining every last drop of his cum. "I'm not letting you sleep tonight." Ippei's miserable new life has begun.
