i took good care of my dad for many many years right now. my mom and me took him back to live because of some crazy accident. anyway. for many years my mom has no sexual contact at all.... my dad always talking about how much he owns me. so my idea was to ask him to agree that i can have sex with my mom. would have good two points: 1. would be a great thanks to me from him. 2. my mom has needs too and instead of leaving the family or cheating she just can do it with me so everything would be ok. im not sure if i can ask him. my mom doesnt know about my idea, but if i get my dad to agree it would be no problem to convince my mother.. what do you think? how can i ask him? what should i try?
and ideas how to ask and what exactly ask?
