Affairs are great drama

they're not usually rdrama postable because it's not interesting if you don't know the people involved but if you do then it's very entertaining.

irl affairs I currently know about:

wife regularly cheats and has had s*x with 3 different men this year, husband has no idea
bf meets female friend and kisses her whenever he sees her, friend implies it sometimes goes further
wife went to a party and spent some time tongue kissing some random
gf often meets up for s*x with other guy because bf doesn't please her sexually
wife was having an affair meeting regularly with some guy, husband followed her one day and caught her in the act
gf doesn't meet with anyone but likes sending nudes out across the internet

And there must be so many more happening in secret. These are just the ones where someone's been sloppy enough that they got found out.
