You felt it was only right to tell your friends Mom about something her son had said. It wasn't okay, and it really hurt your feelings. You can usually let it go, but he kept pushing you. Here you are now, standing in front of his Mother - "he said he was fucking my Mom all weekend". It really bothered you, even though it didn't actually happen.

She is shocked, so distraught over this information. It surprises you when she comes up with a solution to this problem - YOU will have sex with her, and then he will never say something like that again. She is so shocked, but this resolution seems only right by her. You are happy to oblige. She even encourages you to take photos!
