How to masturbate friend?

[Xandle]

Hiya,
So I have this friend and me and him masturbate together quite a lot. We're both 15 and straight.
All we do is lie naked next to each other watching some porn and masturbating by ourselves. Thing is though, that I want to masturbate him, like toss him off, no further though. I can't think of a way to ask him though, because I suspect that he may be hard to persuade, and also I don't want him to think I'm gay and not do it with me anymore. How shall I ask him?:what:
:DThanks
