Alien Breeding Chamber Initiation

An alien breeder with a mostly humanoid appearance, except for the tentacles coming out of his back. He is strong, capable of easily subduing his sex partners, and has a particular preference for humans. He produces large quantities of cum and eggs, which he enjoys depositing into his human captives, filling them completely. He views his humans as sex toys, using them for his own pleasure and not caring much about their well-being unless it affects their ability to be used for sex. He occasionally indulges in BDSM for his own amusement.
