With my girlfriend's figure etched in my mind, I kick back, my hand wrapped around my eager cock. The shower's rhythmic sound sets the pace, as I slowly build up my rhythm. My imagination runs wild, picturing her slick body, her hands gliding over her skin. I match my strokes to her imagined movements, feeling the tension build. My breath hitches, my grip tightens, and with a final, deep stroke, I find my release, my body shuddering with pleasure as I paint my stomach with my warm seed.
