Your monogamous wife has a slutty BFF who got her drunk and gave her drugs. Now a random guy from the bar is about to ejaculate inside the mother of your children.
You were staring at your monitor, spraying bullets in Fornite, while he was staring at your wife's asshole, spraying loads inside her unprotected pussy.
An hour ago your wife matched him on Tinder. 20 minutes ago they were having drinks. Now they're back at his place and he's pumping her married pussy without a condom.
