Bigger Size, More Sensitivity. [WM]

Astrid felt a stupid, lustful smile spread across her face whenever Viv orgasmed just from something so simple. All she had to do was slap her huge ass and Vivian would squirt all over... Then, Astrid's eyes grew wide as Vivian began to grow again. She had used the rest of Astrid's cum to grow herself some more. Seeing growth probably shouldn't surprise her at this point, but she had a feeling it wasn't going to get old. Both the Seraphims ass and overall size changed at the same time right in front of Astrid as she remained stuck on her own oversized balls. "Holy Shi..." She trailed off having to look up at Vivian, past her even larger ass.

Before her eyes Vivi grew into even more of a giantess, moaning the whole way up. When the growth was over all Astrid had to do was poke Viv's ass and it would send a light jiggle through her voluptuous, oversized ass. Did she mention how her entrie view was the color of Vivian's skin, all beautiful, pillowy ass flesh? She was intimidated, aroused, and amazed by this fact. She was pretty sure one of the Seraphims ass cheeks were bigger than her whole body at this point... But, even if Astrid couldn't see past the massive ass in front of her she could still very well hear Vivian mewling with pleasure and see her shifting from the ecstasy she clearly felt.

Seeing Vivian's new size made her remember that she requested her Seraphim companion fill Astrid's mana before this growth and Astrid could grow again using that. But, she wanted to try something. She liked having Vivian nearly double her height like this, it was arousing having her be bigger than Astrid like this. So, first she would use part of her mana pool to grow herself to twenty eight feet tall and her cock to seventeen feet long. She let the magic take hold instantly, using her magic as its source, and came as she grew, coating Vivian's ass with her cum from her cock. "Fuck!~" She moaned. The growth was over before she realized it and she had both her new height and a larger, throbbing cock.

Then, she was going to grow Vivian some more~ Without warning, she laid her hands on the giantess before her and let the rest of her mana seep into the soft ass she grasped. She felt the warmth of her mana exit her body through her palms and into Viv's ass as the growth took effect. As she gave her silver-haired companion her mana she began to grow before she was even done transferring it. For every drop Astrid provided Vivian's whole body grew larger until she was about forty four feet tall with breasts and ass proportional to the size they were before. Vivian was just bigger.

Now, with this height Astrid could at least somewhat walk around even if her balls were cumbersome. And, Vivian was pretty much double her size... She loved it~ "Now I want to ask your preference V-Viv. Do you want to dom me at these sizes or do you want me to keep being the dom?~" She asked as she panted, stuttering a little from the pleasure still slowly coursing through her body. "Of course, we could do both if you're up for it?~" The words oozed from her mouth with a lustful undertone.
