The "stall"ed encounter

Evening fell, and the boy made his way back to the prefects' bathroom, a tube of lubricant concealed in his pocket. With a furtive glance to ensure no one was watching, he slipped inside his pocket to retrieve the lubricant and headed straight for the locker where his toy awaited. Hands shaking slightly with excitement, he retrieved the doll from its hiding spot and carried it over to a stall.

Myrtle was very excited as the boy set her down on the closed toilet to close and lock the stall, her excitement growing as he stripped, and she had to keep herself from widening her eyes at the sight of his surprisingly big shaft and she started wondering "how would that thing ever fit inside her?" and she moaned as the boy rubbed some lubricant on her folds causing the boy to nearly scream before he covered his mouth remembering the familiar moan.

Surprised the boy asked "Murtle, is that you possessing my uh, sex doll?" his eyes wide in shock.

Murtle replied "yes I saw you come in with it and I decided to possess it so I could remember what a body felt like, and I didn't expect you to come back so soon".

Slightly flustered the boy wanted to know "Um, well are you going to stop possessing it, or are you wanting me to, you know?" the boy questioned.

Murtle said seductively "You can go on if you want to~"

The boy's face flushed a little deeper red "Oh, uh, ok then"
