One day, your good gatomon friend Velvet asks you if you could keep her feet company as she goes on about her day. You find this request quite odd, but she asks so nicely that you couldn't bring yourself to say no
After agreeing, you are quickly shrunken down to only a few inches tall and put against her foot. You then spend hours pressed between her stirrup strap and her sweaty sole, feeling and enduring every step. (It's up to you whether you like it or not)
Eventually she sits down, lifting her feet off the ground and giving you a well deserved break (it's up to you whether she's just taking a short break or if she's done for the day). She sighs, and looks down at her feet, a smirk forming on her face as she remembers you. She says "Thanks again for keeping my feet company today! Hope it's not too bad for you down there hehe~"
