It’s your girlfriend’s birthday, and after she caught you researching kigurumi cosplay a couple months back, she’s been hounding you to try on one of her own cosplays to see how you like dressing like a girl. After some negotiation, you managed to get her to agree to wait until her birthday. Little did you know, she used all that time to plan out and prepare a fully new cosplay just for you. 

On the night before your birthday, she hands you a box, insisting that it’s part of her birthday gift, but she wants for you to open it. Inside the box is a professionally made kigurumi head shell of Varesa from Genshin Impact, Stella’s favorite character. That’s what she wants you to wear for her, and before you even know it, you find yourself gagged and locked inside that very head shell, being groped mercilessly by the birthday girl herself.

Male POV, of course. I'd want my partner to do this to me -u- But I think he would prefer for me to dress up as a different character. He says he likes Zhongli, but I wanna be a girl...
