Turns out I can

I thought I couldn't bone my bro no matter how hot he was after he got Second Puberty, no matter how hard his teasing made me.

How wrong I was.

Eventually he, now she I guess, lost her patience. She stopped just teasing me and took the initiative, really trying ti seduce me and eventually just outright kissing me and telling me she wants to fuck me.

Ever since that evening we've been boning almost every day.

Right now we're boning in the back of my car while Miyuki drives us to a convention we're going to. Miyuki is very much ace and doesn't give a single shit about the two of us fucking as long as we don't try to involve her.
