BIL using our bedroom for intimate purposes

We arrived home from holiday last night. BIL has kindly been cat-sitting for us, popping in twice a day, but not sleeping here overnight. This is important.

This afternoon, I've been sorting out a few things in our room. The sun was shining in, and as it hit the mirror I could clearly see strange marks - handprints, quite high up, and what I think is a willy mark at hip height. They are quite noticeable, so I'm sure they weren't here before we went away.

I suspect BIL has been entertaining himself in our bedroom, either alone or with a partner. He's single and the thought of him bringing a hook-up into our bedroom makes me feel ill.

I've changed the sheets (just in case his activities culminated in our bed), but I don't know if I can bear the thought of him cat-sitting for us again if he does this. But DH will think it's strange if we don't have him back, and DCat has never been to a cattery.

Is there a way I can subtley dissuade him from using our home in this way, without offending him?

I've added photos, but they aren't very good because my phone doesn't seem to focus on the mirror surface.

Bumsex against a mirror sounds dangerous, it’s just asking for 7 years bad luck.

DH is at work, and it doesn't seem like the sort of conversation you could have when one person is in a busy office.

But also, I'm in two minds whether or not to mention it to DH at all. He's quite protective of his DB, and historically he's been very reluctant to say anything that might upset his family. The most likely outcome is that he'll be irritated at me for putting him in an awkward position.

Then you need to say when he gets home “bloody hell brian, there’s a perfect impression of your weener here on the mirror, were you nude when you got the suitcase / cat / your snorkel set down?”

Is there a gap on top of your wardrobe? Could he have been reaching up to get the cat, steadying himself, when unfortunately his trousers and pants slipped down just as he got hold of the cat so he couldn’t catch them before they fell??

You need to get your spy kit out. Dust for fingerprints and check its not yours / your dhs

I mean he could have been having a wank / shag against your bedroom mirror but there are about 400 other plausible explanations.

Those are the only two explanations I can think of 😅

Ha ha! I wish I could, but I can't think of any convincing pretext for asking DH to provide me with his fingerprints.

But I hope you're right about other plausible explanations.

All you know is there are marks in the mirror. Could be absolutely anything.

Do you mean willy marks on the mirror? I don't really understand because your photos look like a towel. Personally I'd be more concerned about the cat. So no, I wouldn't have him back. Who knows what he's been up to.

😮

I can see there are marks on the mirror but that’s…quite the conclusion you’ve come to!

Just lift them off his phone with some sellotape. Jesus woman, Where’s your ingenuity? They’re not identical twins are they?

Surely no one would push up naked against a bedroom mirror in passion in case it breaks.
Was he doing it for the 😂- and a reaction like this?

Well, exactly! It isn't even fixed to the wall - it's a rather rickety mirrored sliding door on a built-in wardrobe. I wouldn't want to put any weight on it myself.

But I don't think BIL is a practical joker.

Could it be from the cat’s wet nose?

Which one is supposed to be the willy mark?!! 😳

Picture 2 looks like one of those Jesus in toast images 😂

The willy mark is the long, thin one that isn't a hand print

DeathBanana · 03/08/2026 18:15

There’s only one way to know for sure. You need to find a way to get a good look at BILs willy and see how it matches the mirror impression. That’s as much help as I can offer. The rest it up to you. Good luck!

Sherararara · 03/08/2026 18:16

“OP accuses BIL of rubbing his willy all over her mirror before going forever NC. Her DH never forgives her and marriage ends.
Returns home to find the cat standing in its back legs licking the mirror.”

dontmalbeconme · 03/08/2026 18:17

The simple solution is to stop asking him to do you massive favours, if what he does in your house is unacceptable to you.

“Thanks for feeding the cats. What happened in the bedroom? There are prints all over the mirror”

Are you 100% sure the mirror was clean before you left & it wasn't your own DH leaning up against it holding another mirror and trying to get a view of himself because he had a weird rash in a intimate area or something?

I can imagine someone doing that, in fact, I feel like maybe I have at some point? 😳 😂

I'm fairly sure the mirror was clean, because the cleaner comes on a Friday and we went on holiday only two days later, on the Sunday. She usually cleans the mirrors, but I suppose it's possible that she forgot.

I would love to believe it was my DH leaning against the mirror to examine a rash, but wouldn't he need one hand free to hold the second mirror? And there are definitely two hand prints (left and right) here.

Sorry but I think this thread is just a silly wind up.

DeathBanana · 03/08/2026 17:57

I think you also need to carry out a reconstruction crime watch style. Like if he were behind the lady where are her boob / bum prints? Which makes it more likely he was alone. You need dh to strike the likely pose if they’re of similar heights and see if the marks align. Also there’s no evidence of the ahem conclusion to the act so you need to consider at which point he may have become prone against your mirror. A reconstruction is the only way 🕵️

That's true, no evidence of a conclusion! I can be grateful for that, for sure!

“What looks like a willy mark at hip height”. Phrases you never thought you’d read…
