even if i recorded and did what you asked you would still doubt it. you should sift the ghostbox recordings people have about their succs moaning etc. don't remember if the op links have them or not. and those things have been done anyway prior multiple times in past threads. you can move objects yourself as well with telekinesis using crown chakra. what probably would however convince you is to tell details from your past what only you knew.

you can't convince people like him, even if she manifested out of thin air and had sex with you while he is watching in the corner he still wouldn't be convinced. people like him thrive off the feeling of being superior to others and they will do anything to cling onto their perceived superiority.

Even if they are real, which you seem to believe they are, they are demons. By nature. Satan (who is female) was the original 'Old Empire'. 'the Domain' is here to take back the Earth.

'the Domain' is ruled by masculinity and the hierarchy is similar to communism. 

This makes succubus (satan) worse than a commie.

*warning* if your succubus claims to be part of 'the Domain' she is a dirty liar.
