Medicine!

"Wait, like cough syrup? That stuff is gross. I'm not sick anyways. Or do you mean ****? I suppose that could be fun. This place is already pretty trippy, though..." You blurt all this out in a rush only to trail off.

Abe just squeezes his eyes shut and breathes in deeply through his nose. You get the sense that he is struggling with his frustration for some reason. Finally, he replies, "No, dimwit."

"Hey-"

"I mean the field of medicine. No, that does not mean a farm that grows cough syrup. I meant becoming a doctor and helping people. Do some good for once in your life!" He pauses, "well, I suppose we're past that anyways."

For a long, embarrassing moment, you just stare at the horse head on the wall. When you finally find your voice again, all you can manage is a simple, "oh."

Abe continues to look at you expectantly. This is the most patience he's displayed since you've met him. You realize he wants you to say if you agree or not. You take a few more moments to mull it over and then announce your decision.

"I want to be a doctor who discovered a formula to make my wee-wee bigger!" You are just brimming with undeserved pride.

Abe's jaw sways loosely. "I... What...?" He starts but cannot seem to form a sentence. After giving his head a good shake he composes himself again. "Fine!"

You barely notice the horse's discomfort. You're just standing there, eyes half closed, fists on your hips, basking in your amazing accomplishment. You feel yourself swelling with pride. It feels good. It feels like...your pants are getting smaller. Wait, what?

You look down at the bulge straining at your crotch. The pressure is starting to become uncomfortable. You quickly drop trou and realize you're not swelling with pride, your pride is swelling! You're held in rapt fascination as your dick seemingly pours out from between your legs and snakes across the floor. Foot after foot, the head of your cock slips away from you. When it finally stops, your manly member is now man sized! At nearly six feet long flaccid, only one thought fills your mind and you have to express it as loud as you can.

"Woo-hoo! I got a huge willy!" You smile like a buffoon and grip the base of your lengthy penis. You think your hear Abe make some disgusted noise but you're too excited to care. You flop the enormous organ from side to side whooping and hollering in glee.

"Yeah! I can't wait to **** a few bitches with this monster," you shout. "Let's get the baby hard and see what I'm really made of!" You snicker at your lousy joke. "Bring on the hoes!" you shout to Abe. He doesn't respond, but you don't notice. You're already stroking like a mad man in an attempt to get to full mast.

In your excitement, you nearly fall backwards into a chair, but you don't stop jerking off. You feel yourself stiffening slowly. It's building up and the head of your dick is lifting off the floor. You can feel yourself getting harder and longer, but as you do your arms start slowing down. By the time you realize what's happening, everything fades to black and you pass out.

When you break consciousness again, you find yourself laying down in a hospital bed and listening to the steady beep-beep-beep of hospital machines doing...hospital stuff. You have no idea what they do, actually. Nearby, a brunette in what you imagine to be a doctor's lab coat sits, typing notes into a laptop. You look her up and down, doing your best to imagine what kind of T-and-A are hiding under that coat.

Suddenly, everything comes rushing back to you and you sit up to check on your monster member. It's still there. Hanging in some ridiculous sling past the end of the bed. Relief sets in immediately, and so does the feeling of faintness. You drop your head back to the pillow and groan.

"Yes, I'd be more careful if I were you," the doctor-babe drawls out in annoyed tones. "And I suggest holding off on trying to get an erection. In your current condition, you do not have enough blood in your body to supply your brain and penis at the same time. Hence your lightheadedness."

She snaps the laptop closed and stands to face you. The lab coat does little to compliment her form, but you'd recognize the swell of hefty tits anywhere. Immediately, your mind starts churning out lewd thoughts and just as quickly you groan and squeeze your eyes shut until the sensation passes. You really can't get a hard on without passing out. This sucks!

"Really, Dr. David, this is childish," she scolds you. Wait, did she call you a doctor? "This formula to extend your penis is nonsensical hubris of the highest order. How could you be so foolhardy to test it on yourself?" She sighs dramatically and looks to you.

You just stare at her, mouth agape like a fish out of water. You're desperately fighting your instincts here. Despite your valiant effort, you manage to stammer out a single word. "T-t-t-tits?"

The curvy curer just shakes her head at you in disappointment. "Right. Well, I have been going through your notes and I believe that I can create a treatment for you, absurd as it is. Shall we get started?"

With that she does an about-face and walks out of the room. You can't help but stare at her swaying behind as she goes. Soon the clicking of her high heels fades down the hall. Before you know it, you're alone, with just your monster prick to keep you company.
