I've name changed for this.
I'm away from home just now looking after my elderly mum after an operation. My DS(15) is at his dad's until later today and my DD(19) is at home.
She called me last night very distressed as she had been looking for something in her brother's room and found a pair of her own pants in a drawer of his desk (not an underwear drawer so not put there by accident). They were either unwashed or otherwise soiled (sorry but you get the idea).
No-one is surprised that he's masturbating but I have no idea how to approach the fact he's used his sister's underwear. My first thought was remove the underwear (as she has already done) and just leave it. He will know he's been found out and hopefully not do it again. Get a lock for her door and no longer use a washing basket. But that seems to be just brushing it under the carpet and I just got a text from Dd saying she's finding it hard to deal with.
Now, DS is also autistic, he hardly talks to me or DD at all when he's here. He's a very awkward boy and I have no idea how to tackle this with him. Has anyone got any experience of this or helpful suggestions?
