A guy 'recruits' a hiregirl, taking her to a motel where, while he was taking the required shower, she discovered that it's 'that time of the month'

'*What am I gonna do*...' she wonders. '*I already took payment.. they guy's kindda cute... even I'd like to do it... I'll just turn off the lights. He won't notice, and by the time he wakes tomorrow, I'll be long gone!*'

Done deal. After a sexstorm of a night, the guy wakes up next to a pool of blood, with the girl nowhere to be found!!

'Oh God, I must have shot her!' He checks his pistol, which still has a full clip...
'Shit, I must have cut her with my knife!' He runs to the kitchen, where the knives are all bloodfree...
'Damn, I must have cut her with a blade!' He goes into the bathroom, where the shaving kit is intact.

As he lifts his head back up, he sees himself in the mirror.

'HOLY SHIT, I ATE HER!!'
