Summoner: Monster Girl Harem!

With a groan, Vincent grunted loudly, his cock pulsating with pleasure as it penetrated deep into the succubus' depths, feeling her inner walls stretch beyond limits as it slid in further and deeper until he finally stopped.

He repeated this action, pushing deep into her fertile womb one last time, and only then did he begin to pump in and out, holding still for several moments, allowing her to get used to the motion.

Celine moaned softly as she felt the burning pain in her womb subside, but also another sensation as his shaft hit a strange spot inside her, sending shivers across her entire body as she let out a whimper.
