Soooo! Today’s underage fantasy is underage Keith (I hc 11 or 12 or something, adapt for your own comfort level) discovering self pleasuring accidentally and bit by bit when he first joins the garrison and is hanging out with Shiro at his place.

He does it pretty discretely at first & he himself doesn’t realise what it is he’s doing, but Shiro does and he doesn’t know how to breach the subject that it’s something you’re supposed to do in private. He kinda misses the appropriate window (which is the first time he notices)

It gets harder and harder to bring it up. So he doesn’t and he just... gets increasingly flustered and aroused every time it happens. At first he tries to occupy himself in another room if he can find a plausible thing to do, then he stays but tries REALLY HARD to focus on

other stuff.. and eventually he does listen and watch out of the corner of his eye and the focus becomes hiding his erection and even out his breathing until Keith is finished pleasuring himself. Which is sometimes brief and sometimes it can last hours. No ejaculate yet, so

multiple orgasms and hord-ons that can last a couple of hours, if nothing else distracting comes up.

Should I continue?

*hard-ons 😅
