Cause he is a faker. Take yesterday for example. He does up Mona and he and Nina play with her, but he doesn't even take it shorts off. Then they move to the living room and tie Nina to the table and all he does is stick a dildo in her, same with Mona. Are you going to tell me that if you were him, you wouldn't have at the very least fucked your girlfriend Nina during all of this? Much less not try to get into a 3some with Mona. He fails at this so horribly that he has become a joke.
He'll make you think something more is going to happen and then ALWAYS let you down. He'll the up a girl, tickle her, make you think he's going to fuck her, and then he'll untie her and make that stupid laugh of his and then sit on the couch and do nothing.
The only place he is comfortable having sex is in the dark, mostly under covers.
There is a reason he's been kicked out of every voyeur site, including your own. He is an imposter and ruins everything he touches. Get rid of him, please.
