Slippery when wet
This takes place in the shower. Once your hard, move the shower head off of you, fill your hand with shampoo and begin to stroke, use your whole hand and make sure your hitting the tip as much as possible. This will make you weak in the knees so be careful. Stop when your about to cum and count to 10 and start again, this technique will make you squirt every time! Try it. Makes your solo shower a lot more fun.
