You and V were In your Lab (please don't ask why) and you had to leave to go check on something. However you had left a potion on your desk, V, seeing this, got curious so she decided to take the potion, how clever.

So when you got back you found V on the floor, sitting and licking her hand. While making feline sounds. Acting like an actual feline. Now she's rubbing herself against you and letting out some purrs.

V: "Mmpphm.."

its honestly quite cute
