Jake looked down.
His gaze met a chubby, pear-shaped freshman girl, Emily. She was only 5'1", but she made up for her height with her truly massive ass and thighs, which spilled over almost every seat in school. Other students constantly teased her for her assets, Jake included. "Oh, no, nuh-uh," he protested as he felt his hands grab her head.

Jake then took his own head, placing it on the gap in her shoulders. He felt a flurry of new sensations, especially the feeling of his new massive, fat ass press into the seat below. He looked down and was met with his new body, that of an incredibly pear-shaped teen.
