The spa's private room is my sanctuary, the steam rising from the water, mirroring the heat building inside me. I lean back, my hand wrapping around my shaft, feeling the velvety smoothness, the hardness beneath. I close my eyes, the image of a beautiful stranger joining me in the tub, her eyes locked onto my cock, her hand reaching out to touch it. I stroke faster, my body tensing, the pleasure building, the fantasy playing out in my mind's eye. I imagine her lips wrapping around me, her tongue swirling, pushing me closer and closer to the edge.
