I had a plan to give my partner a blowjob as a surprise, but my idea was that neither of us may use our hands. No touching at all except my lips over his cock ;)

I call him, already fully naked to tell him I've got a surprise for him. Obviously he was very surprised. I told him that he may not use his hands and the same goes for me. Also that as he just start to cum, I am going to remove my mouth from his cock and he can shoot anywhere he wants.
