Hidden in the confines of her bedroom, Erika had trouble thinking straight in her canine form. All she could feel was the increased churning in her massive balls as her drooled-covered knot was swelling to its largest girth. The heavy member jerked in the air, a rope of pre spewing from its tip and splattering on the floor in front of her and some on her nightgown.
"Think, Erika..." she tried to force herself. She felt repulsed by herself, her mind filled with images of her friends and dogs mating; at the same time, the fleeting thoughts made her hornier by the minute, the strong urge to cum worsening.
But she needed to ingest the goo to maintain a female form, or she would revert back to having a hard-on and turning into a dog in a matter of hours after having cummed...
Erika let out a low canine moan as she gave the hard fleshy member her most determined licking. It was so big it would not fit in her muzzle, and its wild throbbing made the task even more difficult. She whimpered in frustration; she needed more stimulation.
She spotted her favourite plushie - a very soft bear - on the floor near her bed and grabbed it with her teeth before securing it under her hips, grinding against it. Her huge cock smeared fluids all over it in a matter of seconds and she fastened her pace, squeezing the plushie under her weight and paws as she rammed her buzzing monster into it.
A spasm shook her lower body as a burst of cum shot against the soaked bear. Erika stiffled a howl and looked down as the waves of pleasure were hitting her. The dark red swollen cock jerked uncontrollably, ropes of semen splattering on the plushie and the floor.
Erika opened her muzzled and gulped as much as she could catch mid-air. Trembling as her deforming digits dug in the floor, the sensations within her became a blur. Her climax mixed with the cracking of her bones back into place. Her tail and muzzle shortened, fur disappearing from her body.
Her nipples pushed out and the fabric shifted as swelling breasts filled the remaining space. The flesh of her cock softened as it dangled lazily between her thighs, slowly shrinking back into her body along with her ballsack.
Erika was still on all four, licking the splatters of goo from her plushie and fingers, her nightgown in disarray. Slipping a hand between her legs, she let out a relieved sigh as she felt totally normal girl bits - a tiny button and a very moist slit. Now she would remain like this for a while hopefully. She had school the next day...
High on hormones, she climbed into her bed with the wet plushie, too exhausted to care about the stains she had made on the floor.
She slept like a baby.
As her phone chimed its morning alarm, she hit snooze and laid in bed, her eyes adjusting to the low light of sunrays filtering through the curtains.
Sliding a cautious hand between her legs, she relaxed as her fingers met no hard pole this time, just soft lips and a cute nub. She squirmed and rubbed her tighs in contentment, and felt she was wet. It's true the goo that helped her keep her female form also made her feel like a bitch in heat.
She would have to try and behave at school today.
Erika felt her insides spasm as she remembered how the need to mate had overcome her last time, and she almost fell pregnant from her own dog. The mixture of shame and pleasure was still resonating within her.
A familiar warmth was radiating from her groin.
Running a moist finger over her nub, she could feel it harden and swell lightly; like any clit would. Circling around it, Erika enjoyed the smooth skin there as she moved her hand lower. After a second of hesitation, she slid a finger in her slit, gently rubbing her happy button with her other hand.
Her breathing became heavier as the familiar sensations returned, her breasts jiggling lightly as she increased the pace. She felt a hint of frustration; her fingers were no match to a swollen knot. Whimpering softly, she grabbed her bear plushie; the fur was matted with cum, but the scent emanating from the bear exerted a strong pull on her.
Erika squeezed the plushie against her groin and started grinding her clitoris against it, biting her lips to keep her moaning as low as she could. Arching her back, she could tell she was getting close...
The bedroom door swung open, and Erika hastily pulled up the sheet to hide her hands and the wet plushie.
"Good morning sunshine! Did you miss your alarm? You need to get up for school, honey..." Erika's mother said in a cheerful voice as she came in, putting a pile of freshly ironed clothes on Erika's desk.
