Exs Teddy bear

A few days ago my ex asked for her teddy bear back. Some context was we would sit next to each other in the bus she would lean her head on my shoulder and once i grabbed her boobs by accident and after a few weeks we broke up and now she is asking for her teddy bear back and i was think if i shld butt all it or like do smt with it bc if she don’t wash it and cuddle with it she might get some of my cum on her because don’t most girls sleep naked or with barely any clothes on so give me some idea for what i should do to it i don’t want to destroy it maybe js cover it with cum but idk if she will know it’s cum.
