"Hey there. Come here often?" The voice whispered in my ear. It was really deep and smoky, like a lounge singer's. It sounded made for talking dirty. I turned around and almost fell off the bench. There was girl, about nineteen, wearing a sky blue spots bra and short white athletic shorts. Her long, tan legs were ended by white-and-orange running shoes. Her long brown hair was tied back in a ponytail. "Sorry, I was out on my early morning run and I saw you and, well, I just had to stop. You're handsome." She whispered, then pole vaulted over the bench and landed next to me. She stuck out her hand. "Hi, name's Rosalie."
"I... I'm Connor." I stammered, grasping her smooth hand. I felt the wave of charge come over me, and a heat in my groin. I felt a huge boner growing in my jeans. "It's kinda early for a jog...a girl like you looks like she needs her beauty sle..." I stopped myself. "Stupid, stupid." I muttered. I looked up at Rosalie and saw she looked hurt. "I know. I'm a sexist horndog and now you're going to squirt me with your water bottle and leave. Listen, I understand per..." "Shhhhhh." She shushed, putting her finger up to my lips. "I was only kidding. Listen. I'm hot, you're hot. I know we literally just met about two minutes ago, but I want you to have this..." She reached into her shorts pocket and pulled out a sticky note and a pen. She scribbled on it furiously and handed it to me. "I have to get back on my run. See ya later." Then, she winked and ran off down the path.
I unfolded the paper and saw a phone number with Rosalie's name written under it. I looked up and watched her run away, her butt bouncing up and down in the tight shorts. That was too much. The wave of static washed over me again and I moaned as I felt something wet squirt in my underwear. Then I started feeling strange. I looked down at my hands, turning them over in mounting horror. The fingers were shortening and fattening, thumb backing up at the wrist. My fingernails were getting long, black and sharp. Glossy black fur started growing on my rapidly shortening fingers, sweeping down my hand until it reached the end of my long-sleeved jacket, where I felt it tickle a it grew up my arms. My hands (paws?) grew in size and rough pads formed on my palms until I had two huge panther paws where my hands should have been.
"What's happening to meeeeeeor...." I moaned, and I actually felt my voice drop two octaves and become way more growly and low, eventually degenerating into feline howls and growls. I felt pressure on my face and something appeared in front of my vision, teeth sharpening and forehead pushing back as my eyes burned and changed to lime green.. Fearing what it was, I brought my paws up and felt it as it grew out some more. The glossy black fur had already grown on it. I felt my ears move to the sides of my head and become rounded. I looked down both ways of the path with suspiciously enhanced vision and saw no one coming. I was stuck in a park miles from home with the head of a black panther. I jumped up, yowling in terror, and started running towards a nearby clump of trees. With how fast the sky was lightening, I'd be spotted within minutes if I didn't hide soon.
I felt my thighs and rear grow in size, straining my pants while they became powerful back legs and haunches. My spine lengthened and my head brushed up against the branches of the trees. My stomach and chest pushed out, ripping my shirt in the front. My shoulder blades got pushed closer together and my arms, now completely front legs covered in the glossy black fur, splayed out in front of me. My pants ripped open and my feet lengthened as my toes inflated into huge back paws with claws and fur. My back cracked and I was pitched to my four legs, the force of the fall causing a long black tail to pop out just above my rear, hanging limply between my huge, muscular haunches.
I looked down and back around at my huge, muscular body. Just like the curse had said, I was transformed into a panther after I had had an orgasm. I felt like throwing up, to be honest. I opened my muzzle to scream, but all that came out was a loud, feline roar. I took a few uneasy steps forward, almost tripping over my huge paws and tail at first, but I got used to it. I started padding through the wooded area, looking for a small animal (preferably not human) to drink it's blood so I could change back.
Or should I? This was my first transformation. Should I get used to my form, so the next transformation won't be so bothersome? It was a tough decision to make. I lied down in a thick path of bushes so I wouldn't be seen while I thought my options out.
