[Unsolved] Help me ID this manhwa

I was reading this manhwa about a year or two ago. It was about a group of friends taking turns sharing their wildest sexual experiences with each other. If I recall correctly, one guy's experience was having sex with a sister of one of the guys from the military. Another one was this guy making a woman his sex slave and making her do things in public and in her workplace.

Eveything was basically disturbing.

Help me out 😭
