Kei has dick and balls. May or may not be bigger than her partner's and it's negotiable from 'whoa' to 'impossible'. Absolutely up for her penetrating or being penetrated by partner's of any gender or configuration!

Obviously, if she's the one getting it from someone else, but focusing on working up to it, in either direction, is good.

Or this. Frotting, handjobs, or come up with something even more creative I guess?

Gentle, loving smut is fine, but she is a Getter pilot - she's less of an adrenaline junky than most of the others, but Kei's still hella strong and totally down for fucking or getting fucked hard.

Kei's also not firing blanks, in case, y'know, anyone wants to get in on that, or even continue on to or jump straight to pregnant sex too.
