Simple request for a Halloween story

Figured I'd ask now so that by the time Halloween comes around a decent story (or possibly multiple) can have the chance to be written

A "Halloween party" story where a guy builds up the courage to ask some girl/s to ballbust him by going to a Halloween party where costumes with masks are mandatory (kind of like a masquerade ball) so he doesn't have to see the face of the girls he is asking. (Doesn't have to be part of it, but he could not realize he knows the girl/s he asked personally)
