'Hoarding: Buried Alive' Sneak Peek Exclusive: Rotting Meat Hurts A Marriage (VIDEO)

Would you invite friends over if your parents were both hoarders?

We've got an exclusive sneak peek at the upcoming episode of "Hoarding: Buried Alive" (Sun., Jan. 29, 9 p.m. EST on TLC), which follows 22-year-old Hervey as he tells his friend Derrick for the first time that his parents are hoarders. In this reveal, they find a mountain of rotting meat just sitting out in the kitchen, including a pork tenderloin that's turned green and an old chicken carcass.

But like most hoarders on this show, Hervey's parents are hiding some heavy truths under all that filth. During the clean-up, shocking secrets about their marriage and sex life come out (including some rather strange sexual preferences), suggesting that it will take more than a thorough house-cleaning to heal the family.

"Nobody should deal with that," Derrick says. "It's a deathtrap!" But everyone in this situation should be so lucky to have a friend like that to help. "I was embarrassed at first," Hervey admits. "But after a while, it was like the greatest sense of relief knowing that the secret that I had had my entire life finally was out. I don't have to hide it anymore."
