I can't remember the name of it but I know it's not baked sweet glasses...so the story line is that these two guys go on a business trip together and in the middle of the night the seme gets up to pee and sees the butt of the uke hanging out and then it happens again the next night and when they're at lunch together the seme daydreams a little tentacle rape scene of the uke...and then I forgot the rest...

Moved to Yaoi/Yuri.

I think it's Stranger
