My sphincter, pleasuring me increasingly.
Captain's orders

The Host

He tried turning around and prying open the sphincter and trying to go back the way he came, but despite his best efforts, it barely budged.
A problematic date
Arlen licks the sphincter the best that he can while he uses a hand to stimulate wilton's genitals.

Balto's training begins.
She sees that balto's sphincter closes with more force. "relax balto" jenna says looking at balto. she pushes the toy against the anus of balto, but his hole does not open.

Asylum
His claws swirled around the rim of his sphincter, playing with the sensitive skin as though it had a mind of its own. he took a sharp inhale when he felt his claw push inside of his tailhole.
