In the steamy bathroom, a horny exhibitionist teases their lover through the frosted glass, their hand working their throbbing cock. As the water runs hot, they stroke faster, their breath echoing in the small space. The anticipation builds, and with a final, firm grip, they explode, painting the tile with their sticky cum. The lover outside, hearing the guttural moan, smiles, knowing they've pushed their partner to the edge.
