Ingo almost never bottoms. He just doesn’t enjoy it. The most penetration he's comfortable with is a few fingers, MAYBE a small toy. Occasionally he'll indulge Emmet if he's in a particularly submissive mood but it's almost always a no-go.

Bouncing off of that, he's still a switch, they both are! They usually take turns domming.

Ingo's sex drive rises significantly post Hisui, but returns to a more balanced level after a while. Emmet has always been extremely horny.

Ingo has a guilt complex the size of the goddamn moon and Emmet loves to sexualize it. "You're so disgusting, corrupting your innocent baby brother like this" "Only a sick fuck like you could be attracted to their own twin" etc etc. It makes Ingo hard every time.

If Emmet ever drops the "big brother" line mid sex he's getting folded like a pretzel. He does this frequently on purpose.

BREEDING KINK. You can knock that cis man up Ingo just keep trying.

Ingo is a hard-core masochist and while Emmet wouldn't call himself a sadist he's more than willing to scratch that itch.

Ingo has an oral fixation and extremely sensitive nipples and both of these facts are so fun to Emmet. It truly is so easy to shut that man's brain off.

They have can and will continue to get nasty at work. In the office, in the train car, in the tunnels. Not frequently, but if Emmet doesn't edge Ingo for an entire shift by groping him through his clothes between challengers AT LEAST once a month it hurts him :(

Mirror sex that is all. Or missionary. Or any position that allows them to see each other. Due to the brocon.

Okay trans Emmet time. Ingo helps Emmet with his testosterone and they both get off on becoming more and more identical.

After Emmet gets/recovers from his hysterectomy Ingo doesn't let him out of the bedroom for at least three hours.
