Erin vs Damian the Sex Demon #9, 10, 11 (Pixiv Fanbox)

Erin lay exhausted on the bed. Her face...body...was covered on the demon's semen. After he came inside her he pulled out and ejaculated all over her prone body, and while normally she would have fought back...having intercourse with a sex demon really takes the energy out of you.

Mustering enough strength to sit up, she glared over at the sleeping figure next to her. Normally demons disappear after abusing their humans, but his eyes and horns had stopped glowing... an indicator that his guard was down.

Grabbing a steel collar from her nightstand (because of course Erin would have a steel collar in her nightstand...) she latched it around his neck and rudely pulled him off the bed. She had a room in The Facility that would be perfect for her revenge...
