Help him

I decided to help him but not let him know who was helping him. I touched his balls and he jerked. He stopped masturbating and his eyes went wide. I began stroking his cock since he had stopped. I stroked his cock with one hand and kneaded his balls with the other hand.

He didn't say a word. I wondered if he even realized a person was helping him. Maybe he just felt like his own genitals were moving on their own. I couldn't see my own hand so it did look like Jake's cock and balls were moving on their own.

He reached down to touch his cock again and I moved away. I didn't want him touching my hand. I didn't want him to understand what was happening to him. I caressed his nipple or his face, whatever he wasn't touching at the time. It was fun to keep him guessing where he'd be touched next.
