Chapter One: What Happens When You Don't Lock The Door

Sometimes Natsu came over at the worst possible times in Lucy's opinion. She didn't know what drew the Fire Dragon Slayer over to her place along with his friend Happy but at times it really got on her nerves. Especially if she had just gotten out of the shower. Now it wasn't as if Natsu hadn't seen Lucy naked before but recently…she had undergone some changes. Some would consider it drastic and others not so much…basically her lower half had some extra equipment which had not existed until recently.

When it had happened Lucy had been extremely panicked at the fact that she now had both male parts and female parts. The first person she talked to was Mirajane since she trusted the barmaid to not be judgmental, the barmaid then pulled Lucy aside and explained everything. No, this was something that would not go away, in fact it was sometimes a side effect that female mages developed especially if their magic was strong enough. Also, she was not the only female mage with this issue.

"It's nothing to be ashamed of." she remembered Mirajane saying with a smile, "Levy was worried too when it happened to her, but if anything it's just a side effect of something greater. Take it as a testament for all your hard work."

Lucy sat in the bathtub and stared at her flaccid 7 inch dick, of course she would be just as well-endowed in that area too, as if having large breasts weren't enough. 'If this is a testament of hard work….maybe I shouldn't have worked so hard in the first place.' Tentatively, she brushed her fingers against her cock and shuddered at how sensitive it was at the head before running her hand down to her balls, her breath hitching.

'That…actually feels good…different…but good.' Lucy thought as she ran her fingers along her balls once again, whimpering as a sensation of pleasure shot through her. 'Really good.' She added as she used her other hand to grab her dick which she felt throbbing beneath her hand 'Oh Gods…I'm getting an erection!' she thought as a blush spread across her face. She started moving her hand up and down her cock, massaging it while her other hand grabbed her balls, squeezing them roughly. Lucy cried out at the sensation and started panting loudly.

"So…good….hnng!" Lucy whimpered, 'I'm jerking myself off…I can't believe I'm doing something like this!' She removed her hand from her balls and moved it up to one of her breasts, pinching one of her pink nipples before moaning as her penis twitched in her hand.

'I'm getting close….I'm really close….I'm going to cum from my penis!'

"LUCY! ARE YOU HOME? LET'S GO TO THE GUILD!"

Lucy felt her heart drop to her stomach, 'Natsu?! Oh shit…' she pulled her hand away from her cock and bit her lip, 'Damn…I was so close…I don't know if I can get it back down! Crap!'

"Luce? Where are you?" she heard Natsu ask and suddenly she heard the sound of the knob turning.

"Wha-NO! Natsu don't come in!" Lucy shouted, but unfortunately for her it was too late as the door swung open and the pink haired dragon slayer stood at the door while Lucy still sat in the bathtub with everything exposed including her raging erection.

Dark eyes widened slightly as the dragon slayer took in the sight of his friend, "L-Lucy…"

She really needed to start locking the door.
