Even without the relationship being specifically D/s, as a sexual fetish, there is the idiomatic "Hachi" seme — a person whose attachment to the uke so much like that of a puppy or a dog, so full of exuberant, unconditional and, I dare say, naive love, he is drawn with a wagging tail and doggy ears as a visual pun.

Hachi-Tachi?
What do you call an Uke that's dominant and a Seme that's submissive??? Is this a thing?
