I will rate this 8/10 because the only problems here come from the weird scene of a nipple drinking air literally has no sense (but this being a short story I can't shoot the author for this). Nipple drinking air comes from a weird phenomena and I am confused how the hell that scenario even came because I am sure that girl is not a werewolf. Like any other way the author could've done it would've worked. Hell, even a scenario where the crossdresser is so asleep that this happens could've been more explainable.
