As I walked through the door to Jenny's room, I saw her there on all fours. Her skin was popping and rippling as her muscles bulged and shrank, then bulged again. Her spine was snapping and reshaping, forcing her back to arch and bow as she struggled to get her form under control. Her skin was drenched in sweat, and her black hair hung limp around and over her face.
“St-Steve...” she whined. Her eyes were wide and golden, and her teeth were sharp and pointed, but not fully the murderous fangs of her monstrous form. “You n..nuhh..need to goooo...” she snapped her jaws in the air as fur rippled across her shoulders and withdrew once more, only to bloom again.
“Is there anything I can do to help?”
“I....I....” Jenny said with a moan, before tightly shutting her eyes. Her body finally shrank more as her muscles deflated and her bone structure shrank. The golden shine in her eyes darkened and became mostly brown again. The whole time, her face was contorted into a look of discomfort, and she let out soft grunts of pain. Finally,she forced herself up into a sitting position as she panted, seemingly from relief. “I..I can't control it..all that adrenaline..it's driving me WIIIIIILLLLD....” she snapped her jaws again, and now stalked over to me on all fours. She reached up and grabbed my hand, nuzzling her face against it, then licked my palm and fingertips experimentally. “Mmmmhhhrrrrrr...” she said, letting out a light growl, “You smell so good so good so good TASTE SO GOOD SO GOOD SO GOOD....”
She tugged my forearm with a surprising amount of strength, pulling me down to the floor, and took a long lick from my wrist up to the crook of my elbow. She snapped her jaws again, and once again winced a bit before pulling away. “Steve..seriously..fuuuuuuck..I can't..I can't control it..I'm h-h-holding it back but..I'm go-gonna change again soon...” she whined. “You need to get out of here...”
“Tell me how I can help,” I said again.
“Get..” she took a deep breath, and for a moment, there was no hint of desperation or fear, no hint of the animal at all. “Get Spot. I..” she began to pant as her control already began to slip once more. “I need to cum, Steve. I need...I need..I need to fuck. Lots. Need to fuck. Need to cum...need to fuck..need to cum...and fuck..run the adrenaline through my system..” She shivered and again seemed to gain control for a moment. “But you need to go because..I like you..I really, REALLY like you and..I...I..don't know what will happen if you stay...”
Suddenly she let out a loud groan, and her eyes went from brown to bright golden again. Her whole body began to heave as she panted harder. Her nails slid forward, turning into dagger claws, and she let out a growl as the black fur stretched across her shoulders.
I had a choice to make, and I had to make it now.
