The 'Keeping Up With The Kardashians' star shared the childhood story with her guests on TV show 'Kocktails with KhloÃ©', where she remembered a particularly ''wild'' night for her mother Kris Jenner and her then-husband Caitlyn Jenner.
She shared: ''I was playing hide and go seek when I was younger, and I fell asleep under my mom's bed, because no one came to find me, that was also sad. And I woke up to the bed shaking!
''I was too scared to leave. So I had to wait for the whole thing! ... Oh I knew [what was happening], the moaning ... It was honestly wild! My mom feels bad about it still ... I'm scarred for life!''
Meanwhile, it is not the first time the 31-year-old television personality has heard her mother getting frisky as she previously admitted she was left ''traumatised'' on hearing Kris get intimate with boyfriend Corey Gamble.
She shared: ''Hearing them have sex is wild and I'm traumatised. Kim and I did. At her house, thank god. We were downstairs, and we just heard like [claps]. It's really a traumatising thing. And the headboard just going ... We were hitting each other like, 'NO!' Kim was like, 'Wait, shh.' And then it was dead silent and then they went again for round two. I was like, 'OK, check please, I'm gone.'''
