A Miyuki Lore Question for You (Patreon)

Under what circumstances do you suppose...

Clarissa first saw Miyuki naked, and vice versa? I have actually thought through a great many things that make up their backstory that have never come up, but I haven't settled on a good idea for this. Consider:

They met in college, Miyuki and Lyta were roommates in a dorm, Clarissa was their neighbor. (Separate unrelated issue, did Clarissa have a roommate? If so, who is she?)

Clarissa would have been the second person Miyuki met on move in day, after Lyta.

Miyuki probably had a crush on Clarissa as soon as she met her, which is natural of course, everyone loves Clarissa. And vice versa, most likely.

So easy answers are: the dorms share a bathroom, and therefore they'd meet in and around the showers, in the locker room at the gym, or after they started a romantic relationship, but those answers aren't very interesting (also dorm bathrooms had individual private showers when I was there, and that was a while ago now). I feel a more memorable pair of scenarios is called for. Consider further:

I'm thinking it should be separate incidents, so one girl is nude while the other girl is still clothed.

It should not be an intentional or engineered encounter; nudity may or may not be intentional, but if it is then they'd meet at random.

They're not in a romantic relationship yet but would be on the way to one; it's more memorable and exciting/embarrassing to see/be seen by attractive neighbor with no clothes on than someone you've entered into a no-clothes-on-activities arrangement with. Also, probably happened pretty early in their acquaintance, knowing how the girls are about taking their clothes off.

I had thought of a nude dare gone sideways originally, because the girls are always doing that kind of thing. But it doesn't make sense for all of them not to be there when the dare happens, dares are very much a group thing. Presumably the dares would have started after this incident.
