As Erika was led away by the hand to the cleaner's closet, something started happening to Ms K. Her face burned as her lips and cheeks became fuller. Her nose became a cute little button, with a slight upturn. Her breasts ached as they started growing fuller. Pushing her bra until they made it hard for her to breath. She ripped off her white shirt as the clasp on the back of her bra snapped.
Her long brown hair turned into that golden beauty. The paunch she had became firm abs as Erika gripped her harder by the hand. Where there was flab or slackness muscle took over, she looked like a gym junkie. Her ass grew rounder as her panties disappeared up her ass cheeks becoming like a thong. Ms K's lanky limbs became thicker with muscle.
Her breasts bounced freely now that she was topless. Teachers walking by, and other staff, only say Ms K and a student going to the principal's office. Erika's penis had grown rapidly. The school uniform had become a tad too small since her growth spurt the previous day. Her breasts were swollen and sensitive, dark nipples pushing against the fabric of her buttoned shirt. Soon enough several rows of teats were doing the same.
Erika crossed her legs in an attempt to keep her canine balls from descending, but she only managed to push the whole package upward and her sheath rubbed against her skirt's waistband. In an instant the furry orbs expanded generously while the canine shaft became thicker.
"In here" Ms K urged.
Using her key to open the door inside, once the light was on Erika closed the door and saw Ms K's stripper asshole. She pulled down Ms K's jeans and panties, as if they were wet tissue paper and then pulled down her skirt exposing her canine penis that was nearly as developed as a boy of 16. This pussy seeking missile knew what to do, this was her third time. Erika drove her rod straight into Ms K's tight, wet hole. Doggie style.
"Ugh!" she whimpered as the dick penetrated her vagina.
Erika thrust harder hitting bone as Ms K's pelvic walls closed on the penis.
"AH!" she wailed as she hunched down
Erika's hand missed her teacher's breasts and instead found her jaw, yanking her teacher to a standing position.
Her balls swelled as she twisted Ms K's head. They kissed as she her teacher rested her head on Erika's shoulder. Erika then shot her wad into Ms K's void. It exploded inside her like a fire hose, as Erika's balls slowly contracted loosing their contents. Ms K bounced on the end of Erika's rod, she tried to get off but hands, that felt like crawls, held her tight as the burning seed poured into her womb. She thought it would be a quick jerk but it went on for a minute, she jerked and bounced in time to the onslaught.
Erika let go of her science teacher and pulled her deflated dick back into her panties and the waist of her skirt. Reality hit Ms K, she had just been fucked by a teenage girl, she thought it was a strap on but it was REAL. Was she PREGNANT? As Erika left Ms K curled up into a ball and sobbed. The Salve wasn't as strong as what Erika and Emily and Melissa had been exposed to. As the effects wore off her stripper like body reverted to her former self, but the seed had taken hold.
She pulled on a janitor's shirt, and sniffling and sometimes sobbing, she went to the bathroom. Ms K felt the seed inside her cooling but she felt cramps, she felt dizzy and woozy. She clung onto the sink in the staff bathroom as her knuckles turned white. Her face was white as a sheet as her B cup breasts started to tingle. They were growing, she had an old bra and she tried to adapt the straps around her shoulders and back.
Her nipples had grown from their small nickle size to that of a half dollar, turning dark brown as the breasts were crisscrossed with blue veins. A faint brown line ran down her belly.
"OH JESUS!" she screamed
Ms K threw up into the sink, something every pregnant woman goes through, just not this quick. Her body was trying to expel the foreign thing growing deep inside her. She hadn't been corrupted like Erika or Emily had been. Melissa was the most exposed.
Erika had regretted losing control and had fucked off like a mongrel dog, when neither teacher nor student returned Emily knew that her experiment had worked. Now to talk to Melissa.
