Del hissed as Ruby's teeth scrapped her tender cock. The sensation sent chills over the shemale's body; causing a needy cry to escape her lips. She panted as the throat around her cock fluttered with it's own moans. Each passing moment causing the heat in her lower belly to grow stronger. She knew she couldn't cum. Not without permission at least. "Y-Yes Ma-master McCall." she purred in a hot breath as her fingers laced into Ruby's dark locks. Pulling them as she tried to sink her cock deeper into the demon. "M-Master,M-Mcall. Can I c-cum on your slave?" she asked, looking down at Ruby. Wanting to spray her load onto Ruby. Just to fuck with her.
