You write very well. Everything flows, and I do not recall an awkward sentence.
As an aside, if I wrote a stopwatch story, I would give the girls very short haircuts.
As much as I like your work, you now have five stories of Ben having a lot of fun with the watch, and only having a few qualms about what he is doing. He chalks it up to power of the watch keeping him perpetually aroused, and he is helpless to fight it. Moreover, Ben is the only somewhat developed character, and I can't follow another five stories with Ben the slacker just having fun with the watch.
He needs an epiphany. Either he will give into the watch and become a slave to its power, or he will learn to harness the magic and do something useful with it. Or maybe you will take this in another direction. Let's learn more about Lilith.
Keep writing. I'm looking forward to a conclusion.
Fantastic story series ! As a breast fan, I'm getting a lot of joy out of this :)
