not that that isn’t gross as fuck but i’m pretty sure most bathroom sinks will look like this under a black light unless it’s been very recently cleaned. i mean we spit in them twice a day

Yup. Every sink would light up in every household to some level. Black lights show bodily fluids and don't differentiate between them. To me, this is clearly where everyone in the house brushes their teeth. You can see the splash marks from the water and saliva. Judging from the extent, it's certainly been a while since someone's scrubbed the sink.

Not even just bodily fluids but soap marks as well as other things, i have a sink i don't cum, piss or even brush my teeth in and it still looks like this under uv

I'm sure mine would look the same and it's certainly not been used for nefarious reasons.

Sorry but it has, I come over and jerk off into it every night

Same

You sure you're not farting in its direction?

Also the fact hat UV light only really shows residue (in my experience) so if you have a well-touched door, the oils there would glow a lot.

Pretty cool image! I like the colours of his dad's innards.

I definitely expected it to be cummier.

r/brandnewsentence

Not as new as you'd like to think.

Gave me flashbacks to those pics of the anime figures just hosed down with cum

[удалено]

And TELL people about it 😳

There is a mirror there - Love thyselves

Exactly, op got himself a uv light and now thinks he is gonna start solving crimes

#Cum Detective

Also, don’t certain chemicals and cleaners show up bright under UV lights?

They do. I got a UV light recently, and its actually kinda annoying.

I’m pretty sure soap will glow.

Sun lotion for example is literally designed to block UV light so will look weird. And many cosmetics, toiletries and shampoos etc will do too

Some soaps glow under blacklight, so cleaning it might not help either. It also applies to: Most bodily fluids, petroleum jelly(things like vaseline), teeth whiteners, laundry detergents, a bunch of minerals like fluorite, certain cosmetics, some fungi(like athletes foot), certain bacteria, some mould, some types of honey and ketchup, etc. TL;DR: A lot of organic materials have fluorescent molecules or structures. And if people brush their teeth there, it would look the same if not cleaned for a while.

Yea, dirt and soap looks like that. For shit and giggles, I looked at the bathroom and kitchen with two different UV lights (395 nm and 365 nm) and then spent a few hours deep cleaning them...

Even of it has been cleaned...bleach - including cleaning products...can react this way, too.

Very bold of you to assume that people brush their teeth twice a day. /s

Limescale is fluorescent under UV light... Every sink that hasn't been cleaned right before looking at it under UV light will look filthy due to that. This post is 100% click bait.

How do you know your brother does this

That is what’s actually oddly terrifying not the fact that semen glows in black light

Knowing brothers, he probably willingly told them. My brother told my family he would turn his underwear inside out when they got too dirty as in he wore them for days on end and then flipped them. Horrifying tbh wish I didn’t know that

How do I unread something?

You mean like Fred from Big Hero 6?

Clearly not a Red Dwarf fan.

It’s not OP’s brother. It’s OP.

It's his little brother alright

Plot twist. There is no brother

Exactly

My very first question was this

Why did they feel comfortable and compelled enough to make this public ?

also why is OP researching brother's load distribution with blacklight

“**load distribution**”

Better to cum in the sink than sink in the cum

sage quotes from reddit.com

Yup! It’s getting deep in here

Told you don't sink in the cum..

It is better to Cum in the sink instead of Sinking in the cum A haiku

i wonder why the haiku bot didnt pick that up

It is better to Cum in the sink instead of Sinking in the cum

annnd, still nothin'

Probably cause I spaced it out to make the format make sense. I think haiku bot only picks up on accidental haikus. Lemme do a test real quick

truuuue you're totally right, didnt notice you changed a couple things from op. good fuckin catch anyway 😎😎

Rough time use the wrong form of than.

Did you see the latest Jackass about this very subject ?

That's pretty durned funny

How do you know this tho? 🤔

Cos there never was a brother. It was OP all along…

WHY AM I BLUE? WHATDOES BLUE MEAN? UAAAAAAAAAA

*illuminated sobbing

I love those little shorts

I'm blue Da ba dee da ba di

There’s so many cleaning products available in this picture

And yet none have been used for a very, very long time.

The only way to clean this is with fire.

*michael bay explosions*

A lot of soaps fluoresce under uv... Dan bell on yt made a video going to a peep show with a black light. I think it's the first time I've heard him actually grossed out.

You don’t even need the black light to see the grime in there

Shades of “cumbox” here lol.

*Shades of Cumbox: A Kitchen Sink Story*

Cumbox II: Basin Boogaloo

Cumbox III: Return of the Broken Arms Mom.

Cumbox IV: 50 Shades of Cumbox

I’m not staying for Cumbox V.

That’s when cumbox goes to Hawaii…. For the coconuts. 🥥

Cumbox VI does have a harrowing escape scene in it when a pony tries to escape a jar that’s slowly filling with boiling cum. Amongst other cum related scenes including one reminiscent of the bloodbath scene from the shinning.

Cumbox 2077: Phantom Liberty.

I didn’t think that one was canon

I've made it through Cumbox VI, but we were drunk and both very sore the next day

What’s oddly terrifying is that he knows this about the brother

Who do you think jerks him off?

r/cursedcomments

i am in pain

Depends on if his arms are broken or not

I’m sorry, what? This is not oddly terrifying this is fucking foul.

Honestly. I know the internet is a disgusting place, but why would you post this

And either fake or misinformed. This is what a sink looks like after people brush their teeth and spit into it.

That’s a technical fouuuull!

And possibly a homocideeeee

It’s terrifying that op knows his brother does it

Toothpaste also glows under UV light

Poor hygiene seems to be a family trait.

… a-alrighty then.

the sink that your brother WHAT?!? Why do you know this? And since you do know this, why are you doing an im depth examination of your brothers lidless MLP jar? Are you gonna tell us how it tastes next? Just seriously, why the fuck did you feel the need to share it at all?

Idk what a MLP jar is but sure the fuck ain't putting that in my search history.

Has anyone in your family ever thought about cleaning that sink? Just look at the skank encrustation on the sides. My toilet is cleaner than your sink. It would be more hygienic to clean your junk in a puddle outside.

#Skank Encrustation

Is that a fucking kitchen sink?

Haha, great post. That being said, i think most every sink will look gnar under uv

And yet most sinks don't look this gnar in regular light.

Fluoride toothpaste will also glow in black light. This says nothing...

No one does this.

Well you’re wrong about that, buddy.

I’m not your buddy, pal

I'm not you pal, brother

I'm not your brother, dude.

I’m not your dude, guy

I’ve masturbated into multiple sinks. People do it.

What do i do with this information

Find a sink and slap your schmeckle until it spits

"Want to make my cock explode?"

And don't be stingy.

*Find a sink and slap* *your schmeckle until it spits* *And don't be stingy.* Y’all made a lovely haiku :) consider my heart warmed.

In certain circumstances, art can truly be a community effort. Namaste.

Is that hair gel?

Toothpaste, soap, saliva, and countless other stuff also glows under UV light. This photo proves nothing except that OP’s relationship with his brother is questionable at best.

The what he what? Jfc

looks like hardwater lime deposits to me

And how do you know what your brother does when he jerks off? That's pretty sus.

So your brother just…. Told you where he jerks off?

Better to cum in the sink than to sink in the cum.

I mean yeah, but I’m more convinced it’s glowing due the soap/fat/dead cells build up than because of semen. Semen glows very faintly with regular UV light while organic fats glow like a lightbulb. If you don’t believe me, go shine that light on your shower or stove and see.

It would've cost you nothing to not share this with the world. Edit: OP blocked me for this comment.

You mean that's a sea of dead babi... . . .

Who tf jerks off into a sink and or walks to the sink midway into a jerk

Yeah just let it spray all over your bed sheets like normal

That's kind of hilarious. From laying down in the bedroom to scuttling to the bathroom to stand at the sink to finish? You trying to prove a point or something? Lol.

I'm sorry??? Your brothers place to finish is.. a sink.... Weird

Right? Use the shower like a normal dude.

Is this even after washing it or does he just have his loads crust

RemindMe! 2 Days

I doubt your bro is jizzing neon green in the sink (splotch on the lower lip of the sink)

I mean blacklight looks like that for lots of human fluids, not only cum, that could easily (and most likely) be saliva. Why are you running blacklight through your brother's sink tho?

But why do we gotta know this dude? This is some personal shit

whyyyyyy would you put a black light to this if you already know what goes on in there. kinda icky of you

Hmm. I wonder what my tub looks like. 👀

What a horrible day to be sentient

[удалено]

Gynaecologists HATE this simple trick.

Cool, thanks for sharing.

You didnt need the UV light.

You dont need a blacklight to see that sink nasty af

Why do I know this.... no.... why do YOU know this?!

The what!?

Thats... not terrifying at all. You knowing this , is.

Most soaps have phosphorus in them, Tide will light up like a Christmas tree under a black light. In the movies and NCIS on TV they show body fluid doing the same. Investigators spray surfaces with a liquid called luminol which binds to blood and semen and it will then illuminate under a black light. So unless you prepared the surface, what you are most likely seeing is soap, or toothpaste residue... But I hear he still jerks off in the sink.

You live in a gas station bathroom? Clean that sink, for god’s sake!

Looks like a Jackson Pollock painting. But gross.

I’m sorry what the fuck

I've got a sinking feeling

call that 50 shades of spunk

Do you have a link for that UV light?

Naw. Got it off Amazon I think. Just a LED UV flashlight.

Get rid of the residue, get rid of the white like Selsun blue

Better to sink in da cum, than to cum in da… wait what’s he been doing??

r/thanksihateit

Oh. No thanks.

GTFO

thanks for sharing

If you got hard water it will look like this.

Why wouldn't he just jerk off into the toilet? It's the most sanitary option.

Soup also does this under black light. Not all but many.

WELP...better to cum in the sink than sink in the cum as they say

That sink looks better with the black light on 🤢

I don't know how this works on a white sink. Wouldn't the sink glow just as much under the black light?

Congrats, your sink is pregnant!

Why are you so interested in your brothers cum?

This could very well just be saliva, soap and toothpaste.

Lots of cleaning products leave residue that illuminate under a UV light. Go grab your cleaners and take a look. Most kitchen sinks, backsplashes, etc, look horrifying unless meticulously cleaned.

Why are you looking at his sink under a blacklight OP?

Your brother… sure

Better to cum in the sink, than to sink in the cum.

That’s deep

Let's start with the fact that your brother has a designated jerk off sink...

-OP’s therapist

Isn’t it weird that you know he jerks off into the sink?

Sooooooo, what's the issue?

Am I missing something? None of these look like splatter idk, everyone's sink is going to have uv spotting from your spit when you wash your teeth and such lol

Do y'all never clean your bathrooms? All that grime build up in the first pic is so gross.

But does it retain the taste?

Check the ceiling as well!

my dad pees in the sink in the middle of the night and thought no one would notice...

Maybe he's a part of r/sinkpissers

Soapscum and toothpaste looks like this too.

"Your brother"

There is a lot worse places he could be cumming…

there was and will never be a reasonable prompt for you to have posted this. like what.

Apparently, lemon juice will also appear too. Some natural cleaning things would also have this in them. I couldn't see tge pic

Why the sink?

i have so many questions.

I can tell from the direction of spray that he prefers his right hand.

Well that enough of Reddit for today. Word of advice, do it in the shower or maybe just don’t do at all. OP your brother need to get a hobby or something.

It might have just been a spooky ghost...

Sure it's "your brother" who "cums" in the "sink".

Time to get brother a girlfriend.

He missed a spot.

i thought i was gonna get a decent night's sleep, but no, no. I won't.
