Each cover of the doujins of this author is a wonderful piece of lewd art but this one is specially hot, the doujin itself is not bad at all either, actually I think this is my favorite Sailor Moon doujin of this author so far, I can't wait to see the next one, BTW thanks a lot for this amazing book...
Somehow I think the real twist might be a sequel where Mamo takes Usagi to a love motel where he has been using ChibiUsa to pay off his debts to a local gang. And no, I didn't entirely make that up.
