Biker Wolf

Have meek, conservative friend from work
Get along really well, but it never really developed into anything more.
Leaving the office late one night
Run into bombshell biker wolf girl
Invites you out for a night on the town
Can’t bring yourself to turn her down
Eventually invite her back to your place
She’s gone by the time you wake up the next morning, you find a note with a phone number on your dresser
Get to work and tell your friend about the girl you met

Completely miss the fact is was a full moon that night

No clue that cute, outgoing wolf girl was your actually your meek friend.
