"Come on, come on..." muttered Morgana impatiently, staring intently at her penis.
Lucy, still wobbily, staggered over to a nearby table. She didn't feel right, but wrote it off as simply being sore from such clinical but hard sex with such a large penis. She looked at Morgana across the room, self-infatuated in her predicament. Then the pain suddenly grew larger and she couldn't hold back a scream.
Morgana spun around and ran over to check. "What is it, girl?!" she questioned impatiently.
"A pain, a big one. It's inside me. Something... Something is inside me, it's pushing... Pushing it's way out" screamed Lucy.
Morgana bit her lip sheepishly, having already clocked what was happening. She knelt down in front of the nude girl, reached up and once again parted her mound. If her plan hadn't worked, the least she could do is observe the effect happening from a better vantage point.
Lucy's crotch seemed normal for a few moments, but then Morgana smirked as it happened. The clitoris perceptibly swelled, pushing past the hood, causing Lucy to wince. The swelling then proceeded up until the point a small, but definite, penile glans was present. The 'popping' as the underside of the bulb formed caused a further wince from the girl. Meanwhile, the urethral duct slowly migrated up until it met the tip of the glans.
"Don't worry, I know what is happening. Whatever you do, don't try and stop it - it won't work... Just let it out!"
"What, what do you mean..?" screamed the girl, petrified.
"I'm sorry to say the spell has transferred to you. Here, let me help..." offered Morgana. She took her index & middle fingers and inserted them slowly into Lucy's vagina. The feeling of a finger running along the expanding muscle in her vagina caused Lucy to shudder and let her guard down. Morgana then leaned closer and started performing a curious mix of cunnilingus and fellatio on the growing organ. Lucy, wracked with pleasure, leaned back against the table and threw her head back in ecstasy, offering no resistance (to Morgana's tongue or to the spell, which continued unchecked).
The penis emerged from her crotch, filling Morgana's mouth, stopping at about 8 and a half inches. Morgana removed the penis from her mouth slowly and finished Lucy off by hand, causing her pristine penis to erupt all over the witches chest.
Leaning over the workbench, recovering from her experience, Lucy's head bowed. She opened her eyes and her heart sank. She tried to get words out between breathes - "I... I... I have... Why do I have a fucking PENIS! YOU SAID THIS WAS SAFE?!"
"I said you wouldn't get pregnant, silly girl. No magic is safe" said Morgana confidently, hiding the fact that she too was petrified and completely out of her depth.
Lucy stood up and angrily lunged at Morgana, who simply held up her hand, suspending Lucy with a magical forcefield. "Look, I'm sorry about this, I am. Clearly we either did something wrong or I missed something. On the plus side, I managed to observe the effects on you like I couldn't on myself. For the record, yes, you now are the proud owner of what appears to be a man's penis - your clitoris became the body and your urethra migrated inside it, just like a man. If you feel the need to urinate, I suggest you give yourself plenty of time to practice - it's definitely strange, especially with that erection. Interestingly, the spell seems to react to a users 'resistance' to the spell. I've got about six inches of growth - the result of my worry and panic about what was happening to me. You, on the other hand, you offered little to zero resistance and as a result, you had a significantly larger growth rate. I must say, you'd certainly please any woman with that!"
"You fucking bitch! You 'encouraged' this growth by... by... *fingering* with me as this shit was happening! You used me as a goddamn experiment! Now we're both stuck like this..."
"Shush girl, I need time." chastened Morgana before continuing... "If that is anything like mine, it's not going to go away anytime soon and your clothes will hardly conceal it. I suggest you stay here a while. I may need you for, err, further *experiments*. Rest assured, I'll find some way to compensate you for this."
Lucy stared impassively. Morgana was her only hope of returning to normality - alienating her wasn't the best idea - but could she be trusted..?
Her mind was straying though. She subconsciously moved her hand up the shaft of her penis...
