putting it back is the key, I cum in my wife and sister in law's cups all the time. Love the idea of my cum pressed up against them all day and the thought that once it gets warm they will smell of sex all day and not know where it's coming from.
I've done this to my cousins wife's swimsuit. We had been swimming all day at the pool and she has 36dd tits so I had a load built up. Went into the bathroom to get dressed up there laid her swimsuit laying on the bath tub. I cam so hard in her cups and just laid back to dry seen her wearing twice since then
