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.

well that dynamic isn't a thread all on its own is it?

id just leave the marks, then comment on them when DH is there. babe what's that make? it looks like a handprint. oh god that's not the shape of your willy is it?

"Where is the other hand print though?" (mildly confused/shocked expression)

Etc. etc.

Lots of men who are straight are really bi sexual. Perhaps for some reason that he hooked up with a man but could not take to his place. I would tell my husband cannot see why you wont

DP has helpfully annotated your photo @WhatTheMirrorSaw and I’m starting to agree with his theory.

The good news is, that’s probably not your BIL’s willy.

The bad news is, it’s probably his arse (or the arse of his latest shag).

I’d burn the mirror if I were you 😁

😂😂😂😂😂 oh please, stop, it's hurting!😂😂😂😂
Best thread ever!

I feel a bit sorry for your BIL chances are your cleaner left her handprints on the mirror and didn’t clean it properly.
The handprints look
too small to be male ?

The cat put on rubber gloves.

I'd be handing him a bottle of windowlene and a duster.

But only if he agrees to wear a French maid costume!

Strangely enough, I unexpectedly bumped into BIL just now. If I'd known I was going to see him, I would have made sure my face was in a neutral expression but as it was, he took me by surprise and I was all flustered, thinking of gay orgies and the other unsavoury activities that have been mentioned on this thread. I could actually feel myself blushing - now he'll think I have a crush on him, for sure!

Do you find gay orgies less savoury than straight ones, OP?

I have felt there is a bit of homophobia behind some of the posts on here - that it's especially disgusting if the imaginary sex BIL was having while leaning flacid against the mirror was gay sex

Applogues if I am wrong.

I’m as bisexual as the day is long and I’m happy to snort childishly at this - it’s the illicit mirror shagging that’s funny/gross, not the sex of the people doing it.

Carry On Catsitting? 😁

Who does your BiL live with OP? I think he’s having a man round to shag him against your mirror.

He's single and lives alone. So, no reason not to take his randoms back to his own place!

I’ve got it OP. The fact it is affixed to the sliding door is key. He was snooping in your wardrobe and opened the door in an unconventional way, sliding it along with hands on the glass, maybe because it was stuck, or he got it stuck open after snooping and he wanted to ease the top edges along in the runner.

Edited

Hmm, well that would be quite an innocent explanation. But what on earth did he have on his hands to leave those hand prints? It took quite a bit of scrubbing to remove them, I can tell you! But I didn't want to leave it for the cleaner.

And also - it doesn't explain the willy mark! Unless he was snooping through my wardrobe in the nude 😱

could you have brushed against the mirror when you’ve just put body lotion on? That can make some odd shapes. 🤷‍♀️

Definitely not

Ha ha, that's very kind of your DP!

Is that definitely my photo? I thought they looked like hands/a willy, but now it does look like a bottom! I can't decide which explanation is worse!

He's single, professional, quiet and shy. A bit geeky. I'd never have anticipated him doing anything like this, but it's always the quiet ones isn't it!

This comment has sent me 🤣🤣🤣🤣🤣 did he bring the lubricant with him to cat sit or has he found a bottle lying around in your home and put it to good use 😅 I’m only asking because I don’t know anyone who would carry personal lubricant with them to go cat sitting 😂

I hadn't even considered that aspect! We use lube (thanks peri) but it's not lying around so he'd have had to rummage in drawers to find it. But surely he wouldn't bring lube to our house? I'd assumed he was suddenly overcome by a moment of madness, but bringing it with him implies a level of planning and intent.

Or maybe he was overcome by passionate thoughts whilst in our house for some reason (perhaps our boudoir photos stirred his loins, but he'd have had to enter our bedroom to see them) and used whatever was to hand, some cooking oil from the kitchen?

EnthusiasticPony · 06/08/2026 12:58

There's a whole lot of assumptions going on here. I would have shown the marks to DH because you may be barking up the wrong tree, a lot! by blaming BIL!

ParsleySageToiletDuckAndBinBags · 06/08/2026 13:59

Maybe it's just my own crooked mind, but I cannot read 'willy mark' and all of the associated drama going on, without my mind instantly going here.

To my thinking, you simply cannot get any more erotic than lard.

KentnotClarke · 06/08/2026 14:29

Op what do you think your DH reaction would be ?
Surely he would fall about laughing rather than.be outraged ?
I would have just innocently shown him the pics

WheresThatCatGoneNow · 07/08/2026 03:43

I really hope this thread doesn't just come to an abrupt stop, with no proper ending.

I'm agog to know what actually happened, but I suppose that's impossible without embarrassing the poor BIL.

I’m not convinced he would. Since it’s extremely far-fetched and unlikely, surely he would hear it as an elaborate and detailed erotic fantasy of OP’s about BIL? As in, if you came back from a nice holiday and your DH had been thinking about what if some very random marks on the mirror were the lubricated imprints of your sister’s tits as she had a secret catsitting orgy — you’d probably not be best pleased.
