Requesting a character with broken arms being masturbated by his formerly platonic friend, perhaps with some dialogue setting it up or the bedridden/injured character bashfully thanking the one 'helping him out'. Honestly it can be any characters since I'm mainly just trying to get some material for this niche fetish, but ideally it would be between (aged up so as to not be shota, maybe just twinks) Killua and Gon from Hunter x Hunter. If a drawfag accepts and uses these characters, I would request that Gon be the injured one making the request for Killua to masturbate him, as I doubt Killua would make such a request. Gon would probably lack self awareness to be embarrassed or bashful so if you take these characters, scratch the bashful part I mentioned earlier. Killua would be embarrassed and bashful for sure.
Basically he's asking for it because he couldn't fap in a long time due to injury so needs a friend to help him out. Honestly it's a big fantasy of mine. No idea if there is already stuff out there like this or not.
