Miki, her heart pounding, lies on her side as the enema hose snakes between her buttocks. The nozzle, slick with lube, breaches her tight pucker, making her whimper. Warm water flows in, stretching her insides, evoking a mix of discomfort and pleasure. She writhes, her breath coming in ragged gasps, as the water fills her, her body tensing and releasing. Her hand ventures down, fingers finding her clit, rubbing in time with the flow, her moans echoing in the room, lost in a taboo, intimate pleasure.
