Tinfoil hat here:
I joked about it here roughly a month ago but do we know for sure that Stoper and L&P aren't the same guy? It would explain both of the insane delays. One tends to pop up when the other has a long lull in releases, among other things.
Also, both have age-play fetishes. L&P likes shota, even his pre-AWAM work (short stories, can be found out there) all involve young boys fucking adult women.
Stoper has the reverse where even his pre-JOHN work is full of old men fucking younger women.
It's all kind of the same thing. Odd that both have things for age disparity sex.
Finally, the art is similar. Very similar. So similar that fans have easily put each of them in the same scenes just by photoshopping Jessica or Sophia out of their respective art and placing them in the other...and it fits pretty flawlessly.
I'm just saying...
