ASMT: Gets angry and says no
From Create Your Own Story
Your mom, despite her intent to keep her voice down, raises it a level. She is completely oblivious to the fact that you can hear every word they are saying. Your mom says, "There is no way this is going to happen. I am not going to do something like that with my son and my sister. I was drunk last night, and things went to far. It is never going to happen again."
Your aunt, also raising her voice slightly, says, "If you don't, then I am going to have sex with him. It is going to happen regardless. It made me horny as hell to watch you suck your son's dick and I am going to do something about it."
Your mom shakes her head and says, "That is just wrong. He is your nephew. You shouldn't think about him like that."
Your aunt, without missing a beat, says, "Until last night, I would have agreed, but you changed that. So we can either give him a threesome for his birthday, or I am going to fuck him without you, and not just for his birthday."
You mom responds with anger, saying, "If you want to be sick and fuck your nephew, my son, then go right ahead. That is your business. I want nothing to do with it."
Your aunt smiles and says, "You will have something to do with it. I will tell you every nasty detail. I will send you video of us fucking. I don't think it would be all that difficult to get him to agree to being on video fucking his aunt, if it means he can take whatever hole he wants."
Your mom shakes her head while saying, "Why would you do that? I don't want to know any of the details."
Your aunt gives a little smile while saying, "Which is why I will give them to you, in great detail. I know you too well, sis. I know that finding out about going down on your son makes you horny. I know hearing about your son and your sister fucking in every way imaginable will drive you crazy. I know seeing us on video will make you want to have a threesome. You have to be part of it. You cannot stop yourself when you get an idea in your head, you have to see it through. Besides, you already crossed the line. You already started it, and now you have to finish it.
