I banged a 47 year old, and then her 21 year old daughter, then the mother again, and then I left a note on each of their cars detailing my perfidy. I specifically mentioned that I hadn't had time to wash up in between them, and they'd both given me head, and done other... less clean things.
Other than that, I'm picked up women for one night stands, and they've decided there was a relationship, and I proceeded to ignore their phone calls and ignorant messages.
The best thing I was peripherally involved in was when an old roommate got a one night stand to leave our apartment by telling her that he was taking a shower, there was bus-fare on the kitchen counter for her, and she needed to be gone by the time he'd washed the smell of her off. I fucking near died laughing, listening to her squalling and howling at him.
And yes, I know I'm going to hell, so don't dwell on it too much. I'm a bad person. We all know this, and I've decided to accept my inner asshole and enjoy my life.
