Something I caught my brother doing..
Okay, so, when I was younger I caught him doing this (He's 3 years younger than me, I was probably 15 at the time)
Okay, potentially gross out time. (But im being serious here..)
He's a severe asthmatic, has a couple heart murmurs, so what he's potentially doing is worrisome.
Basically, it involves his mouth, a straw, a small trashbag, and blowing air into the trashbag. While its in his pants.
I have scoured the internet, google, porn sites, everything and anything, and I can't fathom what the hell he's doing.
Anyone have any ideas?
