She's been REALLY nice

The room was alight with magic, the sole source of light surrounding Nyka's growing form. Not only had her breasts grown larger than life, but the catgirl herself was gigantic. The large bed she laid on was barely able to contain her giant body, her massive mammaries hanging off one side as her lower body pushed past the opposite one. Completely oblivious to her change still, all of her senses were focused on the petting she received. Kallisti's hands were so soft, so tender...The Dark Goddess smiled. She had to rise up to her knees to be able to continue her adorable friend's treatment, but it bothered her little. She felt the radiance of pleasure filling the blonde young woman, not to mention the sense of connection. Her golden eye caught a glimpse of something, a red glow on Nyka's right bosom. Her Mark was forming on the giant breast, as if on its own accord. "How curious..." Kallisti mused, her smile spreading. She was still to ask the catgirl to become her Disciple, but it looks like the young one had already made her decision. Nyka wanted to be a part of Kallisti's closest before she even knew it herself.

Orc-Tek commissioned me to make a continuation to this, a picture from ages past. He wanted arconius' Kallisti to continue making Nyka bigger tits and height wise as the catgirl enjoys the best ear massage she's gotten in her life. (Also yes, Nyka used to be thin )

...You know, I've been meaning to make a picture of this sort for years, explaining that Kallisti's left her Mark on all of my main characters and made them her Disciples. The idea has occurred to me more than once, but I've never gotten to draw it. It's a major detail about my characters, too. -_-;;
If you have no idea what I'm yapping about, go check arconius' gallery out.

Anywho, I hope you enjoy this as much as I enjoyed drawing it.
