The Anatomy Professor (Patreon)

Shelly was the professor's favorite art student. He enjoyed watching her every time she sat down to her easel, always selecting the same spot every class. Shelly always wore tight-fitting clothes that accentuated every curve and, as she sat, her breasts would do this cute little bounce. They were like pure jelly. "Did she even wear a bra to class?", he would often ask himself. He swore he could see her dark brown, nipples through her cotton t-shirts if he stared long enough. Teaching class was a difficult time when Shelly was there. The professor was dying to know what she looked like under those clothes and, at times, his errant mind would imagine peeling them off her piece by piece during his lectures.

It was during one such episode where his mind was adrift that he was startled to see Shelly staring at him with a most curious and unusual smile. It was almost as if she knew what the professor was thinking and her smile seemed to twist into a most malicious grin. In mid-lecture, he began to feel strange, as though he was...shrinking. It was like his body was melting, almost softening as his clothes draped from his arms and legs. His glasses slid down his face and he could feel a mane of thick hair trickling down his neck, tickling them as they fell about his shoulders. The professor's buttoned shirt tightened around the chest area and felt constricting, making it difficult to breath. Everybody in his class stared at him with mouths agape and in shock, everyone except Shelly, who seemed to be besides herself with delight. The professor looked at his body to see what the class was gaping at and, brushing aside a large tress of brown hair from his eyes, he was stunned when he couldn't see his feet for two large bulging masses protruding from his chest.

He ran from the classroom, heading for the bathroom at the end of the hall and, in doing so, almost tripped over his own trousers and now unfamiliar gait. As he dashed from the room, he could hear nervous laughter as his bottom was exposed to the cold air. Upon arriving to the men's restroom and passing a few awestruck college students, he could see in the bathroom mirror what was causing such a stir in his class. Through some unspeakable means, he had transformed into a spitting image of Shelly. The professor could now easily pass as her twin!

Exploring Shelly's anatomy was going to be a considerably easier affair...
