Bounding? Piss? Humiliation? Oh this is what peak looks like, adorable little scene where Io runs to clean her mess as soon as she's free.
Also I don't think Misa is as toxic as Io's family, she's not possessive, she is just protective, and needs to understand where the boundaries are and how to handle it. She is just discovering how SM relationships go and I think she's not being overly mean considering that.
