I've shared it before but a group of friends and I had stuff happen with a buddy's mom - there was a mini local scandal/drama afterwards but very few people knew we were involved with it.

The TLDR is 5 out of 7 guys in our group of friends fucked this dude's mom, all around the same time period
>be me, 12 years ago, 16
>have group of friends, we hang out at one particular friend's house a lot
>he has stereotypically hot "milf" type mom, she's very sweet, house-wife, she used to volunteer for our middle school soccer teams and shit
>we obviously all joke about her being hot but never get any vibes about her
>his parents go through a nasty divorce, his dad was caught fucking a younger co-worker and she got pregnant
>suddenly she's "cool mom". whenever we hang out there, she acts like nothing is wrong but lets us drink, smoke weed, even joins in.
>invites me over, tells me to cut class and that she needs someone to talk to
>fucks my brains out
>swears me to secrecy
>she even says things during it that get me diamonds, like "remember me driving you and the boys home from soccer? did you ever think you'd be getting in my pants?"
>high on the experience, feel on top of the world but also guilty, plan on keeping the secret to the grave
>few weeks pass and one of our friends admits to the guy that he fucked his mom and feels like shit about it
>suddenly a few others in our friend group admit the same thing. We'd all fucked his mom at some point recently.
>except for one guy, lol.
>friend freaks out, not surprisingly. we stop being friends for a long while.
>fast forward again to that summer, a cop catches her in a target parking lot with a 15 year old's dick down her throat. none of us knew him, she apparently met him there
>gets arrested with loads of teen dick pics on her laptop
>old friend moves in with his dad
>she gets probation and sex offender, ends up moving in with her personal trainer
