Erin vs Damien the Sex Demon #17, 18 (Commission) (Pixiv Fanbox)

Erin grinned maliciously as she put the heavy fuck machine down behind her new sex slave. The Director had banned its use after Kaori "accidentally" ruptured the colon of one of the new shotas with it, but the naughty Irish girl wasn't really one to follow rules. "Silly Kaori just didn't know how to use this thing properly, I'm sure you won't mind me testing it out on you, right?" She dropped a lazy glob of spit onto the slave's anus. It wasn't nearly enough to provide any sort of comfort to the anal ravaging that he was about to endure, but she didn't care. And almost to prove the point, she abruptly shoved her red strapon deep inside his ass. A muffled scream came from under the mask.

"Ha! You thought that hurt? You should've thought of that before you came into my bed you butthead!" She bent the Vibra-Max 3000 down and set it to full penetration. Now where there had been a smooth dildo just seconds ago...there was a vicious spiked one. The sex demon panicked and tried to move forward, away from the pentrator. Erin was much too smart for that though. She knelt in front of him and rammed her shit-tinged strapon down his tube gag. Now he was getting it from both ends.
