Choose your own (Sex)venture story

So while i figure out what to do about my other longer stories, I have come up with a concept for a quick short story.
Basically the idea is a character has moved out of home to a shared household located near their university, they are a senior so like in their late 20s this character is probably female but depends on the survey results, in any case this premise doesnt require a backstory or key childhood events for the setup, so it doesnt suffer from the issue I have with my other storys

The fun parts:

1. The characters old and new house are both located in a former mining town, so they are basically generic kit house kits imported by the mining company, so are in many ways mostly the same with some variations due to later renovations.
2. In this case the new house is identical to their old house... except to add a third bedroom they moved the bathroom to a different location in the house, and other than some shifting around of the laundry and new bathroom to fit it all in, the rest of the house is identical.
3. In the new house the character has a bedroom in the same location as their former house
4. The character has a previously unnoticed severe sleep walking problem. In their old house they often got up at night for a glass of water or to use the bathroom, but nobody realised they were sleep walking when they did it, because when sleep walking they only dream about their house
5. The character would previously sleep with no underwear (in the case of a female lead wearing only a nightie) but was also a restless sleeper, the character has claustrophobia so sleeps with (her?) door open, and since (she?) doesnt want to potentially flash (her?) fanny/genital at flatmates each morning or night, has instead began sleeping in boxers and a tshirt
6. each night they sleepwalk either or both to the kitchen for a glass of water, and later to pee in the bathroom.. which of course in the NEW house is actually one of their flatmates bedrooms, where conveniently in view of their bed, is a plastic chair where in their previous house was the toilet, which even more conviently has a vanity next to it with discarded clothes hanging off it, right where our sleep walker might expect to find toilet paper
7. Each morning the sleep walker wakes to discover they wet their boxers, because in their dream they are not wearing any, running out they switch to underpants (or panties) which likewise are soiled each morning, and by friday they are down to a single pair, and so take the risk of not wearing any at all, becuase they need the last pair to wear to university.
8. of course nothing gets soiled on the last night because they were not wearing anything, so presumably after that they give up and return to their habit of wearing nothing but a nightie, even if it does mean flatmates get the occaisional peep show
9. optionally at this point the person whos bedroom they are peeing in each night, who lucky for our sleep walker doesnt mind it at all, since they would be "one of us" perhaps starts doing some bad things such as sitting in the chair when she sits to pee, for a cheap golden shower, or worse, perhaps replacing it with their face, which the sleepwaker mounts to complete business as usual each night - if our flate mate is particularly perverted.
   Or perhaps they just be polite, and simply enjoy the nightly show without taking advantage of it at all, beyond cleaning up the mess.
10. making things less offensive, said perversity at point 9, could instead be the sleep walker comes in and catches the flatmate sitting on the floor or something, and pees on them that way, making it simply funny instead of potentially assault, they could be on hands and knees looking for a sock under vanity and getting sat on, or sitting on floor reading a book, and they end up getting the sleepwalkers dripping bits stuck on their face unexpectedly, unable to do anything but simply grab their butt so they dont fall on them and wait for it to end.. which the flatmate finds equally as enjoyable

Other points:
not much sex in this one, unless face mounting is involved, in which case they may half wake up and start dreaming of getting oral sex each subsequent night.. because that is actually what occurs.
the bedroom has polished floorboards which is why it is so easy for the flatmate to cleanup after, making the story essentially harmless fun in the wider context
the items of clothing being mistaken for toilet paper and dabbed on their crotch could be anything from underwear to shirts, which the flat mate may actually wear the next day for cheap thrills
