Cum in shoes

I have twice in my life used someone’s shoe to cum in without them knowing.

1. We were camping and a girl left her blue flip flops outside. I took them into the cabin and jo’d on them. I cleaned the cum off and put them Back where they were.

2. My SIL left her green flip flops at our house. She changed into other shoes and forgot them. I was heading to her house and was asked to bring them to her. Before I left I jo’d into them. I cleaned my cum off and brought them to her.

I have seen both of them wear those shoes since, and it is a huge turn on.

Recently my wife had me cum in a pair of her heels. My SIL was over the next day. My wife had her try the shoes on.

My SIL loved them, so my wife gave them to her . As my SIL left, my wife said, “you’ve cum in those shoes. Do you like seeing my sister’s bare feet on your cum?”

We have pics of her trying them on. I haven’t seen her wear them since.
