"I'm sorry you have your tumour but there's lots of information on the Internet which disagrees with you" is an all-timer line. The Internet, folks!
That Reddit story is basically creepypasta, except much scarier than any actual creepypasta I've seen on Reddit. "I'm devoting most of my day to my fetish, destroying my body and ruining my life, I've got to stop! ... n/m guys, I'm doing it more. I love Big
Brother Sports Bra."
EDIT: It occurs to me that this episode breaks my general rule of fetish episodes being less creepy if both sides of the fetish are participating, because here we've got both the lactators and the lactat...ees? represented, and it's still revolting. This is somehow worse than the episode with the dudes talking about farting on tiny men. How??
