Demon Lord's Concubine

With the portal open and she barely conscious from that mind blowing orgasm, the demons drag her inside the Lustful Hells, offering her to the demon lord as his concubine. Her new life of pleasing the massive cock of the powerful entity has just began. Every day she would have to think of new ways to entertain her new master, humiliating and punishing her holes with his huge tool. It didn't take long for other heroines to join her as the demon horde kept bringing more and more sluts for their master. If only she wasn't such a failure and kept her ground, closing that portal. But no... she had to give in like the worthless cock worshiping slut she is~
