My junior female coworker is deeply infatuated with me, her superior. I've lied to her, saying I'll divorce my wife, continuing our affair. She obeys my every command, a complete submissive, and today's private hot spring trip is a special occasion. The moment we enter our room, she clings to me seductively, making me even more aroused. In the private outdoor bath, I lightly tease her pussy, and she gazes at me with hazy, lustful eyes, begging for my cock. But I don't give it to her yet—I keep her waiting. Back in the room, I tie her up with bondage toys, tormenting her trembling body with repeated forced orgasms. The more I dominate her, the more depraved her expression becomes—she's a true masochist. "I can't live without you... I need your cock..." Drenched and soaked, her dripping wet pussy finally welcomes my bare cock, and she cries out in ecstasy. I violently thrust my glans against her cervix, making her writhe in overwhelming pleasure—her expression utterly intoxicating. Without a thought for the future, I fill her womb with creampie after creampie. "I believe you're really leaving your wife," she whispers. Of course, I have no intention of doing so. For now, I simply enjoy her as my disposable mistress.
