Erika knew that it was her time, she had moved to seduce Chrissy over the last five months.
Chrissy was waiting for her with her hair down, wearing a black buttoned shirt and skirt with heels and long black stockings. Erika sprayed her crotch, soon the male appendage rose from her crotch.
"What have you been doing to me?" asked Chrissy in a husky voice.
"Nothing that you don't want...." Erika approached keeping her secret weapon hidden.
With strength that was beyond her size she pulled down her skirt and panties exposing her bush. Kissing her fondling her vagina, Chrissy slammed against the book shelf, some falling to the ground, as she arched her head back in pleasure. Erika tore at her buttons exposing her blood red bra.
But Erika didn't want her breasts.
Like a cat pouncing on a mouse she used her abnormal strength to pin Chrissy's arms at chest level keeping her off balance. Then Erika slipped her dick into her teacher.
"What-the-fuck!?" shouted Chrissy.
Lesbian action this was not what she had expected she tried to fight Erika but her resistance fueled Erika's power. Chrissy wrapped her body around Erika like a spoon. Although the size of a young teen girl she had more strength than most men as the salve pumped through her veins. She lifted Chrissy off her feet thrusting deep into her as her dick grew to full size.
"UH!" moaned Chrissy.
The Librarian Ms Croft came in.
"Chrissy you here? We are closing now!"
"I -ah god- I am cumming!"
"Finish it!" whispered Chrissy.
With a roar that surprised even Erika she blew her load inside her teacher. Chrissy held onto her lover as her heart rate slowed.
She then had to button her shirt and hitch up her panties and skirt. Erika smoothly appeared a normal girl. "Stay here..." Chrissy urged.
"How will I get home?" Erika asked.
"I'll come back after 6pm."
Appearing as if everything were normal she stepped out of the late afternoon shadows with a cheery hello to Ms Croft as her guilty embarrassment took over. Lara Croft was a woman in her fifties who looked at Chrissy knowingly. Not enough to probe but sympathy from a fellow worker.
Ahem she coughed. Chrissy looked confused. Lara's gaze drifted to her black shirt
