"I have a different kind of threesome in mind," you whisper to your wife, your eyes gleaming with anticipation. She bites her lip, intrigued, as you explain your fetish: she'll be bound, helpless, watching you pleasure another. Her breath hitches, but she agrees, her curiosity piqued. You secure her wrists and ankles, her body writhing in anticipation. She watches, wide-eyed, as you invite another woman in, their eyes meeting in a charged gaze. Your wife moans, her nipples hardening, as she watches you fondle the stranger's breasts, her own pussy dripping with desire.
