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.

By the cat?

Dirty cat!

Then it must be your willy 🤣

I’ve seen a lot of willy, none of those marks look like a willy outline.

They are not as distinctive as fingerprints but it is there if you look closely and use your imagination.

Really???? Have you ever stayed in a hotel? Imagine the myriad acts that have been carried out there by prior guests.

Besides, you have no firm idea if the marks on the mirror were in fact there before you left. It seems to be a big stretch to leap from a few marks of your mirror to sexual deviance by your BIL, who was kindly looking after your cat. I'd definitely let this one go (unless of course, there is some problematic backstory to do with your BIL).

DozyCrow · 03/08/2026 19:08

Well first off I'd mention to your DH that there are two hand prints on the bedroom mirror that aren't yours and ask if he possibly made them. If he answered no, I wouldn't be brave enough to challenge BIL. However, I would invest in an indoor Ring camera and set it up next time you have him cat sit. You can talk through them so if you get a notification and see anything untoward you can shout "David, what the fuck are you doing?" And watch him jump out of his skin 😂

BlueFahrenheit · 03/08/2026 19:10

I can't make out the photos.

Willy mark? Maybe he was masturbating in front of the mirror?

UhOhRatPoo · 03/08/2026 19:10

Please ask your DH to recreate the scene you suspect, so you can compare the marks!

Coconutter24 · 03/08/2026 19:10

Do you have any sort of cctv on the outside of your house?

WhatTheMirrorSaw · 03/08/2026 17:21

I can't quite imagine, but I think he must have been leaning against the mirror with no underwear on, and his arms stretched up, palms pressed against the mirror. But why?

But … but… you say you think he was alone? So how would he be having some Alone Time with both hands on the mirror?

I am SO confused.

If you find smaller cat prints inside the hand prints immediately call the authorities.

And tripped then put his hands out to steady himself? Maybe the shock made him go limp so that would explain the odd smudging?

Limepickleontoast · 03/08/2026 19:18

I'm having visions of Rose in Titanic in the back of that car with the hand print on the steamy window 🤣🤣🤣🤣

LordEmsworth · 03/08/2026 19:18

"Intimacy purposes" - having a wank in someone else's bedroom is not in any way intimate 🙄

Does he not have mirrors at home?

I think the assumption is that BIL’s willy was being pressed up against the mirror whilst he was being pegged.

But surely it would move whilst his body was being moved and so the smudge wouldn’t look anything like a Willy 🤔

Ilovelurchers · 03/08/2026 19:24

Is your bed still made in exactly the way you left it?

If so, I doubt he has been shagging in your room. He would use his own home for shagging, surely. Not yours, where he has to avoid the bed and can only have sex against the rickety mirror.

Pet sitters are expensive. And you have no proof this actually happened apart from some weird smears on your mirror. I would leave it.

(Though it's odd you can't discuss this with DH. How is your relationship generally?).

CheeseWisely · 03/08/2026 19:25

I can ask DH to press his willy up against a mirror and see if it matches the impression? He’d be up for it I’m sure if I read him this thread.

pizzaHeart · 03/08/2026 19:26

WhatTheMirrorSaw · 03/08/2026 18:09

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.

Edited

Well you can leave out fingerprints and investigate willy mark first.

shellyleppard · 03/08/2026 17:18

Why does the pictures show a towel not the mirror?? The last one looks like a thumbs up... pointing to the right 😂

I think the willy one looks like an upside down thumb. Perhaps DBil has a thumb shaped willy? Or a willy shaped thumb?

shellyleppard · 03/08/2026 19:28

@WhatTheMirrorSaw, is it possible that he spilled a something on himself, took a shower, wrapped a towel around his waist. Coming out of the shower spotted a spider high up on the mirror. He went for the spider but as he leaned in, the towel dropped and he smashed his "willy" send his hand against the mirror?

How likely would that be? 🤔

😂😂😂😂😂
The stories get better & better!

I don't know what that is (except that it allegedly has something to do with Prince William) and I don't want to know!

😂

Maybe you mean polo?

Please recreate the photos with an oddly positioned towel too for authenticity.

“Hi DBiL, thanks for cat sitting…. By the way, there’s some odd marks on our bedroom mirror, did a pigeon get in and fly into it or anything?”
