Shampoo
All you have to do is take all your cloths off. Then poor alot of shampoo in your hand. Go up to a waist high counter, cup your shampooed hand and put it on the edge of the counter and place your penis in you hand. Gently squeeze your penis and push it in and out of your hand using your hips. The shampoo is very exciting on your penis and the hip motion makes it seem alot like sex.
