have you tried asking her to shit in your mouth, and if that doesn't work tried paying her like $300 for it? your sister could become the escort!

That would never work, she's skittish as fuck. & she tells mom literally everything, including all of her bf's secrets (which i think is pretty fucked, and makes me even more paranoid of dating than I already was)
I wouldn't risk asking her something like that unless I was madly in love with her. However, I'd be just as happy if any girl shit/pissed/puked/burped in my mouth. Really, she's not special to me at all, she hasn't been for a long time. Probably why I don't feel any remorse for doing this shit

ask you sister to be your girlfriend!

I remember another user here was making his sister eat mexican food and enter shower just after, so she has to use toilet while he's still in the shower.

FUKKEN GENIUS

have you ever checked if you had worms?
they are known for inhibiting these kind of disgust response

>>140693
obviously just the fantasies of a deranged pervert. How would he "make" her sister eat mexican food? And how could he possibly know for sure how her body would react?

not either of these anons but I've thought about putting laxatives in my sister's drink before. I had it all planned out, with a small audio device ready to be hidden in the bathroom, and a generous helping of ex-lax placed inside a plastic cup, which I would've snuck inside the glass of soda she left on the table while she went out.
I ended up being too chickenshite to do it, partly because I didn't have the guts to poison her, but more so because I didn't want to make her extremely ill and have this shit blow up in my face (not literally).
One time I also thought about turning the toilet valve the other way during the day while she was all by herself, so she wouldn't be able to flush her crap (she's pretty dull so she wouldnt have figured out the reason why the toilet wouldn't flush, she'd have just assaulted the turd repeatedly with a plunger until she gave up and cried)

>>140695
not OP but is there a way to do that without spending any money or leaving my house? I already look at my shit in the toilet everyday and don't see any worms in it.

>>140700
"here's some mexican food I got for you as a gift while also getting some for myself", then observe how her digestive system reacts to it, then in the future continue giving her mexican food, and setting up hidden toilet cams and microphones of course

>>140695
Is there any proof of that? I thought that was just a retarded conspiracy theory from /x/ and /pol/.

some people just cant comprehend fapping to pretty women being stinky

I can't comprehend fapping to women being stinky.

is well known that parasites affect the host behaviour.
affecting fear and disgust response is one of the more common example, like rabies increase the fear response toward water or toxoplasma increasing risk taking behaviour.
even symbiont like the gut bacteria have a very large effect on the host .
is possible that people partaking in these kinds of fetish are simply more likely to be stricken by parasite, but the opposite sounds very plausible to me.

I had a porn one time called TURD RAIDER

have you ever marked your territory on any of your sister's stuff?

>>140978
nothing beyond some dead skin pieces that came off my nose from sniffing her panties too hard

i wish i had a brother that would do those things to me

>>141478
post bewbage with timestamp

>>141478
If that were true, then you'd record a video of yourself farting and post it for us to fap to.
