>>717804it's probably closer to incest. Like gays are usually attracted to a kind of "other" like how Bears like Femmes, and vice versa.
I'm gonna go with Incest. But like you can't judge them for it, even siamese twins need loving.
The thing you haven't asked is which one's hand is it. Cuz like if one jerks off and the other comes, then it's kinda gay and incestuous, but if one jerks off and he comes but the other head and hand aren't involved, then it's only kind of incestuous and not gay at all.
