Lucy

His instincts naturally lead him to Lucy, she already thought he was a creep so he didnt have much to loose if this was a joke of some kind.

But when he got to her house, he couldnt find her. Searching, he found nothing, until he went into the bathroom.

His dick grew hard at what he saw.

"N-N-N" Lucy stammered as she saw him staring at her naked in the shower.

Her shock vanished and a look of anger grew on her face,

"NATSU!!!!!!!!!!"

Natsu gulped. This ring better work.
