Oh, so he's not a freak... that makes sense, actually!! So no crazy stuff, just Iku teaching Ushi while they tangled their tails, telling him what to do in a very low and slow tone, which Ushi REALLY appreciates because it make him feel comfortable and safe all the time (which is very important, yes yes)

"You can touch yourself here" Iku says, taking Ushi's hand and guiding it to his *****

At first it's strange, but Iku tells him that the best way to make Jehi feel good is basically by learning how to enjoy himself, knowing some sensitive but also ignoring other so he can discover them with Jehi (also, that everybody's different, the only way Ushi will learn how to pleasing his mate is by asking him directly "what do you like? Do you you want me to touch you there?")
