Mike decided to turn back into his normal self and go home, but no sooner did he have the thought than he heard a key turning in Anna's front door. He hoped at first that it was last night's fuck back to pick up something he missed (or maybe to go another round), but he knew he doesn't have a key. It had to be Anna.
Mike ran into the closet and hid, knowing that Anna would panic as soon as she saw that the apartment has been lived in. His mind raced as he thought about all the things she'd see: condoms in the trash, club bracelets still strewn on the floor, and who knows what else. Then Mike realized that she'd think the place has been broken into, and soon start looking to see exactly what had been stolen. Including anything in the closet.
In an amazing stroke of luck, Mike remembered that he had stashed the gun in the closet so that none of his sex partners would find it. He reached up in the dark, found the gun, and breathed a sigh of relief. He started thinking of some ideas.
