"Now, pet, take a deep breath, and then exhale it slowly…"
My unsuspecting pet takes a deep breath, and as instructed starts slowly exhaling, not realizing that as she does so her control over her body diminishes, causing her muscles to relax. Just as she has expelled almost all of her breath, I push the plug forward hard, causing it to completely invade her ass and the flange on the back to slam against the contour of her asshole.
"AAAAHRG! IT HUURTS!"
Tears stream on her cheeks as she looks at me with a betrayed expression. I lightly squeeze her asscheeks as I pacify her.
"Sorry, pet, but if I wen slowly it would have hurt more. Now, while your ass is being stretched, let me prepare myself…"
I stand up from the bed and motion to Hope to stand next to me, which she does immediately, her juices gushing from her cunt and dripping on the floor.
