The Shokushu school day was winding up, and one gym class was almost finished. The girls in that class just had to finish their track running and they'd be free to head back to the dorms. Little did they know however that there was a spy in their midst.

Hidden within the shadow cast by a tree right next to the track, the dark demon Steel watched the girls run in their sexy little gym uniforms. He waited with unusual patience for the end of gym class, sure that he'd have an opportunity to get one of these schoolgirls alone. Soon all the students were tired of running and left the field. All except for one...

Avery watched the other students tire out, collect their things and return to the dorms. She would do no such thing. Running was a passion that she took very seriously, it drove her to succeed and she would not give out so easily because of something as minuscule as being tired.

With ease she pushed herself forward, legs pumping and arms locked at her side. Her pace was quite impressive, though Avery had been in track for nearly her whole life, as soon as she learned to walk. She owed her lovely nubile body to the sport and her passion as well.

The young woman stopped to stretch though, her small gym shorts riding up her taught little ass, giving a peak of white cotton panties. Her legs were spread a little wider than shoulder width apart, her hands reached down, torso twisted to the left. This was a normal stretch, one she exercised with caution though. After her horrifying encounter at the beach she wouldn't be so easily surprised.

Steel grinned as he saw the one student that remained on the field. He'd been hoping she would stay behind. That sexy body was going to be fun to play with.

She stopped close to the tree he was hiding in and started stretching, and he knew it was time to act. Out of the shadows, three black leathery tentacles rose up as if growing from the ground. The tentacles lifted slightly, then launched forward at top speed, in an attempt to grab the girl's ankles and lash her wrists together.
