Despite the horrendous OC that makes my heart burn, the story isn't all that bad.

I wouldn't call Entropy horrendous, but there is a lack of anything to him. The only indicator about his personality at all is the idea that he likes to cross-dress. Otherwise, he has nothing to show. He just willingly goes along with all that happens, with no reaction beyond the minimal required. He doesn't really show much excitement at the prospect, he doesn't actually voice confusion when he wakes up, he doesn't really do anything. Entropy could have just been a sex doll, and most of what would have happened would have been the same.

The story itself has a few minor technical flaws, but as something that is likely just supposed to be a little piece of porn, it's fine.
