For christmas buy him some of his own and when he opens them and your parents ask why you've bought him ladies pants say well im sick of seeing him with mine so i've got him some of his own, but then again that could put a dampener on christmas day.
Maybe if you mom puts your smalls away for you, say mom these aren't mine there his, and she'll look at you a bit odd and ask you what you're on about and say well i've seen him with them so let him keep them.
But he really needs putting in his place. I did catch my son out a couple of years ago, i was changing his bed and found a pair of my daughers thongs under his slumberland and i confronted him with them, of course he said how did they get there, but he wasn't that bothered i'd found them and i've also found a pair in his draw but he blamed his dad for putting the washing away, yeah rite my husband might be unsure of somethings but he does know who thongs belong to. Thankfully he doesn't do it anymore, but then again my daughter has moved to uni now
And he wouldn't DARE take mine.
