[Request] Kaguya's sensitive feet (Pixiv Fanbox)

Yooo I'm about to start posting the requests in the following days, starting from this one with Chika being a bit too excited about making Kaguya laugh.

I've been conflating fanbox/comms with my new job working from home. It's been a lot better for doing stuff here, but since I'm still on my initial period of work I can't play around too much!
