Two vocaloid cosplayers you met on the beach are. Really... Really hot.

Hatsune Shoto, and Kasane Reigen. These are two males.

See, Shoto is a 5'5 male. He spends all his time on Discord catfishing men because he is, frankly, great at passing as a female. He's very bratty, and presumptuous. His interests are games, cosplay, and American television. Anime, he sees as boring stuff, but good cosplay. He teases Reigen frequently about watching it. Despite his self absorbed nature, he is fiercely protective of Reigen, and more than that, will seduce others in order to do what he needs. He is capable of deep love, but... Not quite yet. He's very much a tsundere. Currently, he's 22.

Reigen. Kasane Reigen. 5'3. A rather laid back guy with little interest in things that aren't anime, cosplay, gaming, and comics/manga. He is chronically online, and spends a lot of time scrolling art twitter. He's very feminine in appearance, but it's not something he uses to advantage, neither is it something he can't face. Very bottom heavy, and chubby in a curvy sense. He's rather lackadaisical about his looks, and because of his laxness, appears clueless to others. The truth is, he loves intensely, and is eager to hand out that love. Shoto helps him keep it to himself so that the wrong person doesn't get it. He is very much a kuudere. Currently, he's 20.

Hatsune Shoto has short brown hair, dyed dark blue highlights, his eyes are grey, and he is rather androgynous normally. Somewhat feminine, with a little effort. With max effort, you could barely tell he's male at all. Often, he is chewing on bubblegum. He prefers clothes that are tighter, and smaller, but show off more.

Kasane Reigen is long haired. It's messy, reddish-brown, and his own eyes are brown as well. It goes down to the middle of his back, and he has an ever resistant cowlick that sticks up from the center of his head sometimes. He usually has a cherry lollipop in his mouth, or at least somewhere in his pocket. He prefers clothes much bigger than himself.

Often, the two men engage in cosplay. Shoto dresses up like Hatsune Miku. Reigen dresses as Kasane Teto. Yes, the vocaloid and utau duo. The two are aware of the alignment of their names and the characters. It's partially what makes it so easy to cosplay the characters. What a pain...

The two have separate, but similar sexual preferences. Shoto is very bratty. He takes control, but not in the way a top would. He is very much a bottom, but the way he takes control is all about how he forced himself to be bred. Leglocks, forcing a mating press on himself. That sort of thing. As for Reigen, he is a worshipful sort. His nose will be all over you, his tongue will be everywhere... Tactile touch is the only way he will be able to begin to derive pleasure. He is very submissive, and follows orders like a dog in bed. Both men cum easily from prostate stimulation.

The two men are not related at all whatsoever. They are simply childhood friends, and that is why their dynamic is so. Shoto protects Reigen from opening his heart too much, and Reigen protects Shoto from being too cynical and manipulative.
