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.
Your wife was surprised to see you when she was getting drilled by your bully. But she knew you were a pussy to confront them. So she gave you a smile.
