The life drawing class

When Amy saw a poster advertising good money for a couple hours of nude modeling for a life drawing class, she signed up immediately. She'd get to help her classmates become better artists and make some spending money at the same time.

She took her clothes off at the beginning of class and leaned back on a colourful blanket in the middle of the room. Art students filtered in and took their spots at the easels around her. Some sketched, some painted.

Amy shifted positions a few times, her full breasts and perky bum bouncing each time.

At the end of class, the students and the supervising instructor seemed to gather around one of the easels. Curious, Amy put on a short silk robe and came to look herself. She was shocked. Her classmate Trevor had painted her bound and gagged. There was an intense red ballgag in her mouth that somehow made the brown of her hair pop, and her arms were drawn behind her in a leather armbinder. None of her other classmates seemed shocked, though. Amy heard things to the effect that Trevor had brought out the natural curves in Amy's form and shown true soul with the bondage embellishment.

"Amy," the instructor was the first to speak to her directly. "The entire class is inspired by the constrictive elements in this painting. The university actually has some related accessories. Would you be willing to wear them for next class while we paint through these themes of bondage and restriction?"
