I'm sure you all have got this planned out, but maybe the player could use how long they have to their advantage. Maybe waiting awhile, but not too long will lead to a still sane and functioning Kiro, but sex is on her mind way more, and she might keep the PC on her ship for a few days at a time to use as her cum-dump, similar to how Xanthe keeps the player in her dungeon for 4 days. As I read this, I realize it sounds pretty similar to what happens if the PC loses the drinking contest, but in my head it's different. Like, maybe she would actually wear the PC on her cock, just carry them around on her dick dumping her cum in them while she does....whatever Kiro does in a normal day. I would be down for that. Then again, I'd be down for several herms wearing my Steele for at least a day.
