New Year's party. At everyone's request, Youmu changed her ghost half into a male, but her ghost half was utterly drunk. It suddenly forced itself on her, and being unable to match strength with a male version of herself, Youmu ended up in quite the predicament. Thankfully, after watching the two of them, everyone else paired up with their own partner, bringing the New Year's party to a lively conclusion. But Youmu, on top of spoiling the party, got her only good set of clothes all slimy and was soundly and stickily punished by Yuyuko.
...And they all lived happily ever after.
So yeah, I guess this is genderswap. That said, I don't think any party that ends in an orgy can really be said to have been "spoiled".
Also, there's a poll attached to vote on Youmu's next partner, and "Gently with Sakuya-san" is winning by a fair margin.
It's fine. It's just masturbation anyways.Whoa..Nooo! Miss Sakuya, don't look!Noo. Stop it, spirit half.
Even though you're me..
Even though you're me....More?Not..Not inside!
