I'm pretty well worked out and my chest is fairly smooth; I kind of like running my fingernails around on the taut skin and touching my sensitive nipples. As well as that, a small patch of soft blond hair nestles in the middle of my chest, between my pecs, and I enjoy playing with that when I'm wanking sometimes. Peter seemed to find all that pretty interesting too: he peered over at me unashamedly as I fondled and caressed myself.
I even ventured to become a little more vocal as I masturbated, gasping and sighing as the waves of pleasure washed over me. I was careful not to overdo it and steered well clear the amateur theatricals that girls sometimes think they need to put on. I just stopped suppressing the sounds that I normally make when I'm wanking.
Peter's response to this was slow and fairly tentative. He seemed fascinated to watch what I was doing but didn't seem willing to apply the same ideas to his own self-pleasuring. For a week or so he just looked over at me while he did his standard thing: right hand pumping his cock with a fairly average rhythm, left hand lying at his side.
But then, late one night, once we'd both started jerking ourselves after we'd both been on the phone for over an hour to our respective girlfriends, his left hand got involved in the action. As nonchalantly as he could, he raised it from the mattress and laid it on his balls. I say, "laid it" because he seemed uncertain about what to do with it: he just sort of placed it there and let it sit there for a while.
He let his left hand rest on his balls for a minute or so and then, making very gentle and subtle movements, he started caressing them with his fingertips; running his fingers through the thick black hair on his balls, as if slowly and gently combing it. The movements were slow but sensual: in complete contrast to the steady and workmanlike masturbating of his cock by his right hand.
He looked over at my face and saw that I was watching him. His cheeks went a little pink and his expression betrayed the fact that it was from embarrassment rather than excitement. Before he had time to withdraw his hand and act like it had never happened, I reached for my own balls with my left hand and made a point of rubbing them to reassure him that this was a totally natural thing to do.
He looked down at what I was doing, his left hand just resting against his balls, and watched me kneading my own smaller pair between my fingers and thumb for a few seconds. Then his own hand returned to fondling his, and we lay like that for a few minutes: the two of us jerking our cocks with our right hands and playing with our balls with our left hands. Both of us looking down at ourselves, and then over at each other.
Peter's left hand soon began losing its inhibitions and he began running his fingers over the large paired mounds of his balls, as if gently tickling them. As he did so, his right hand began steadily speeding up as it worked his foreskin, pulling it up and down the thick shaft of his cock with a new-found fervour.
