Nice story, I've been hooked :)
I imagined Luna didn't want MC to see Skyllar any more because she was the girl fired when MC used coins from the future, but it doesn't looks like it.
The hooded guy may be MC from the future trying to change his past ;)
Just a thought, but it would be quite a shock to MC if he had sex with the daughters in the present, then have sex with the mothers in the past, finally to learn he is the father.
