#3 of A Bottle of Demon Juice


Just a few minutes ago, I was having a peaceful lunch with a friend of mine, Leigh. I spiked her drink with the Demon Juice, and now I was here, watching the 7-foot tall woman transform in front of my eyes.

"I want you to have sex with me."

Her voice was strained, and her eyes were welling up with tears. I knew they weren't tears of pain, but instead as if a million stressors, social expectations and the like were being removed from her shoulders.

The once curvy, perky girl was becoming something very different. Before I had a chance to reply, she hunched over and groaned, clutching her stomach. I saw that her neck had grown longer, and something was amiss about her skin. It seemed to be turning a strange shade of yellow. I didn't know what to do. I remained at the door, double checking that it was locked.

There were a few things you had to understand about Leigh. She was the kind of girl that fits well with a group, an extrovert, but as such she's a victim of peer pressure. A virgin, and already having a boyfriend, it had taken me a long time to break down certain walls, to help her understand that enjoying pleasure wasn't a sin and didn't make her a slut. Now it seemed like the Demon Juice had removed the rest of the walls.

I went to her side, stroking over her back, "Are you ok?" a stupid question. As I stroked her back, her shirt ripped, and she let out a loud gasp of relief. She stood up, and her long hair flowed away from her face in a spectacular display, the kind you might expect a swimsuit model to perform.

Her face had changed. Her nose and mouth had formed into a snout of sorts, short and rounded, sort of like a horse's, but softer. Little bumps had poked out at the top of her head, and her ears had lengthened and swept back with the rest of her hair. It struck me then that she was turning into a giraffe!

The source of her pain became apparent. Her breasts, already supple and plentiful, had busted out of her bra, and the remains of her shirt and bra were slipping off of her form, torn and useless. It gave her a savage look, as if she was a survivor from an excursion on a deserted island. The look was very appealing. With my eyes locked onto her chest, I hardly noticed her rise up. She was 7 and a half feet tall, two feet taller than she had been, and most of the growth was in her legs and neck. She wasn't growing any taller, but changes were still happening. Her breasts, right in front of my face, still seemed to be swelling, and her panties were stretching by the moment as her already curvaceous hips were becoming wider, supporting herself on those long, shapely legs.

"I want you to have sex with me..." she spoke more evenly, her soft hands cupping my cheeks, "That's all I want right now."

What could I do? I nodded dumbly, licking my lips.

Fur sprouted from her flesh, and the strange yellow coloration of her skin became apparent. The classic giraffe brown blocks of color burst into life across her form, a patchwork of tan and brown that seemed tailored to enhance her appearance. She slowly moved down to her hands and knees, and I had to stand just to keep my hips level with hers. My hands slowly moved over her round, strong rump, and suddenly her short, whip-like tail burst from her spine, shredding through her panties and causing her final article of clothing to fall to the ground, useless.

The aroma of her arousal struck me more powerfully than her tail did, and I found myself aimlessly grinding my hips up against hers. She craned her long neck back to look at me, her hair turning a darker brown as a mane formed all down her neck, "Take ‘em off."

I knew precisely what she meant, and rapidly fumbled with my belt and pants, kicking them off. My bare shaft, throbbing hard, pressed between her rump cheeks.

The sound she made was delicious to my ears. It was a sweet moan of lust, of sheer enjoyment. Those social walls were still crumbling, and as each block fell from the foundation, she let herself go just a little more. Her hips began to sway back against mine, sawing my shaft between those powerful cheeks. I returned with a counter motion, taking my time centering myself. I didn't want to go off too soon, and if I didn't focus, she'd have me climaxing before I could make the final plunge.

I drew my hips back, lining my shaft with her slick sex, teasing it by swirling my tip around her clit. She shuddered, delighted. I pressed forward, piercing those lips with a little, inaudible pop, sliding myself easily into her wet folds. She was so warm, so tight, but it wasn't long before I had to pause. My shaft had pressed up against her cherry, a snug little piece of flesh, ready for me to pop it.

"Do it." She cooed to me, watching me with glazed eyes. My thumbs delicately stroked over her wet lips, and I drew my hips back nice and slow. I closed my eyes, and made the final, fell stroke, bursting through and into her deeper depths. She let out a shuddering gasp that I'll never forget; it was the sound of forbidden pleasures, finally realized.

We met each other's thrusts, a soft pat, pat, pat sound with every collision of our hips. Her transformations were complete with the formation of her hooves. A giraffe girl, my friend Leigh, and now I was rutting her like an animal, my legs shaking with the effort, threatening to buckle. My fingers dug into her flanks, gripping her to keep stable, to guide her hips into another collision with mine.

All worry had disappeared, all tension between us was melted, and Leigh was finally experiencing something that I had long wanted to teach her, and she loved every second of it. Her heavy breasts swayed beneath her as she rocked on my length, begging me for climax. I gave it to her with a strained grunt, locking my hips flush against hers to fill her with gush after gush of seed. The warm liquid rushed into her and around my shaft, her juices and mine dripping down her lush thighs. Her arms gave out on her, and her front fell to the ground, leaving her hips thrust in the air at a new angle. I took advantage of that, pumping down into her, drawing out my climax for a little longer, using my pulsing shaft while it was still hard.

I rested against her body, my legs still shaking a bit. Breathing deep, we savored the afterglow, and I delicately stroked over her sore lips, serving her like I had always intended. She was beautiful, even more so now that the Demon Juice had drawn out the best in her.

I glanced over at my pants where I new I had stashed some of the mysterious fluid into an eye dropper bottle. At least now I knew what it could do to a person, and it certainly seemed to have a theme. I gazed then to where our hips were joined, my shaft going soft. I pulled out very slowly, eliciting a soft groan from the well-rutted giraffe girl.

Leigh let herself fall to her side, resting on the floor, still breathing deep, lost in her head. I took the opportunity to clean myself off just a little, and pulled out the mini vial of Demon Juice.

Possibilities. What would I become? Lizard? Cat? Bovine? No, I didn't want to try it that way, not yet. But I did have a little idea.

I opened the vial. The sweet scent met my nose and I had to struggle not to drink the liquid myself. Instead, I dropped a single drop onto my shaft, and rapidly capped and stuffed away the vial into my pants.

By the time I turned to face Leigh, the liquid seemed to have disappeared into my flesh. I moved to her, caressing her side while I waited for the changes to come. New arousal pulsed into my shaft as I touched the giraffe's soft body. I cupped one of her breasts and gave the nipple a little teasing with my tongue, drawing another little groan from the tall girl.

A sharp spark traveled through me, and I glanced down to my shaft. It was swelling, rising up, and changing shape. The pink length shot a thick stream of pre across Leigh's stomach, I couldn't control it! I reached down, tentatively touching the swelling length. I winced at the sharp feeling of pleasure. It was almost painful! I refrained, settling in to watch as lightning bolts of pleasure traveled up my spine. Was this what it was like for Leigh, and my pet snake Mizu when they went through their transformations? I didn't notice any other parts of my body shifting, but my shaft seemed to be going wild.

Suddenly, the skin split along the sides of my shaft in three places, like three red dashes drawn along the side. That's when things got weird. The slits spread open, shaped like almonds, revealing multitudes of vertical tubes (perpendicular to the aim of my shaft), all colored a vibrant red. They seemed to glow with a faint red light, and pulse, creating a rippling effect from base to tip. Over the top of my shaft, thick ridges started to form, something that I knew was made for the females. Three ridges, situated above the tube slits, formed along the top, rubbery in feel, and very flexible. They were thick, fat, and made to bump against that clit without hitting it, even with the hardest of thrusts. The tip of my cock began to shift as well, becoming more angular. The flare of the gland stretched, forming little bumps, almost like fins on the side that writhed just a tiny bit. They, too, felt rubbery and flexible.

My hands explored the new, 18-inch length. It was alien; that was the only way to explain it! As my arousal increased, the tubes filled and swelled, creating knot-like swells, three of them, beneath the ridges. It felt glorious. I could feel every detail of my shaft swell and shift, and underneath my fingers it seemed to beg for attention. I knew I had to try it out.

I slowly guided Leigh to spread her legs beneath me, and slid up between those lusty thighs. She gazed up at me, glazed eyes trying to focus on me. Her hands went to stroking up along my chest in a sweet, sensual way. I pressed the tip of my shaft against her folds, and she let out a soft purr of pleasure.

"Ready for another?" I whispered to her. She nodded in reply, and I pressed forward.

If what I'd felt before was pleasure, then this was nirvana. My shaft's unique shape parted her folds, and immediately the giraffe was drawn out of her state of afterglow, craning her neck up to watch as my swollen, alien shaft drove into her body. Thicker, longer, and improved, it would be the ride of our lives.

The first ridge and knot popped into her body, the smallest of the three. She gasped, and climaxed around my shaft immediately. Her sweet pussy lips clenched and fluttered and urged me onwards, and so with a little thrust, I drove the second ridge and knot into her with a louder pop. Another potent climax from my tall partner, and I drove the final knot into her. I started up a rhythm, the swollen slit-tubes of my shaft creating a rippling that treated her inner folds to what her inner folds would normally treat to me. I could feel every detail, as if my shaft was tailor made for the female anatomy, and not just as a reproductive tool.

I started up a steady rhythm, the fat knots shrinking as I pulled out, and swelling as I thrust in, working with my own muscles.

Before, I hadn't noticed my sac. It had gotten its own upgrade, swollen and practically churning with potency. It now slapped against Leigh's soft mound with every rippling thrust, adding that final ‘pat' to each slap.

It didn't take long to fall into a full rut with her. Leigh worked her hips against mine, caressing over my new and improved cock with her near-virgin lips. Amazingly, she took every inch, all the way to the fat hilt, every detail of my shaft subjected to incredible tightness and warmth, already slick with our previous meeting.

Thrust after thrust, I picked up the pace, going harder, faster, squeezing into her thighs to brace myself. I was sweating with the exertion, and the room seemed to jump a couple degrees in temperature. Her body was bouncing beneath me, those lovely breasts jiggling with every thrust, the perked nipples begging for attention. So I obliged them. I leaned forward, gripping into her hefty breasts; my hips on auto-drive as I dragged my tongue over those thick nipples, suckled them into my mouth, and treated her more vigorously than I had before.

Leigh moaned, gripping the back of my head, stroking through my hair and urging me on, whispering lusty nothings to my ear, her long blue tongue gliding over my neck and cheek, teasing me as I slammed her against the floor again and again. Her hooves clattered on the ground as she tried to find some sort of footing, her hips slapping again and again against mine.

She was begging me to cum in her, and who was I to refuse? I could feel my climax rising like never before. It overtook me with new pleasure. The slit-tubes bulged as a fresh load of seed gushed forward and began to pump into Leigh. The effect was like the blast of a cannon. My hips were forced back by the sheer velocity of the first gush, but I plowed them back in. Each gush forced me back just a small ways, and I slammed my hips back in, fighting with my own body to keep my rippling, climaxing shaft buried into the giraffe's own gushing sex.

My fingers dug into the flesh of her buoyant breasts as we shared the new climax. I filled her with more cum than I would have previously been able to produce in a week, and I was no slouch before this new development either.

Some time during the session, I fainted, lost in a sea of pleasure, blasted from my body, it seemed...
