Surrounded by a Growing Giantess! [WM]

Astrid noticed her cum being absorbed immediately, it was rapid and without hesitance. Once all her cum had been absorbed into Vivian's body she was once again surrounded by soft, pink flesh of the Seraphim's pussy. But that didn't last long. Without warning, Vivian began to grow with Astrid inside her. The pink walls around her expanded and spasmed. She felt herself gain access to more room only for Viv to clamp down on her once again from her orgasms. Before Astrid realized it with everything going on around her there was a hand gripping her legs. Oh no...

Astrid's world became a blur as she was thrust in and out of Vivian's flower. She swore she could hear Viv half moan half shout above her before Astrid's balls - still outside Vivian - began to get warm with that feeling that was beginning to get familiar. Vivian was growing her balls too?.. But, how would Astrid be used as a toy with balls even bigger?.. Before she could consider the idea her balls rapidly began swelling at **** speeds. Not only were they growing from Viv's mana but also from cum. Astrid panted and moaned whilst she remained in Vivi's tight pussy.

The instant her balls stopped growing orgasm took her. The thrusting, the moaning, Vivian's size, her pussy and how it smelled, it was all too much to hold back. As her cock rumbled with the coming seed there was a single moment of silence, then, her cock rapidly began spewing cum violently and her world instantly became white again. She felt Viv expand around her with each burst of cum she provided. And it felt like her balls had plenty to give... She moaned into her own cum, sending bubbles everywhere as more as more white fluid was given to Vivian's womb.

After about two minutes of nothing but straight ejaculation Astrid's orgasm finally subsided. If she had to guess she would say that was enough cum to bloat Vivian to the "broad" size. But there was still something weighing in the back of her mind. If Vivian was going to grow again she wanted... she wanted to be used as her toy. She wanted to give Viv pleasure. But, her balls were to big for that. As if responding to her internal desires a skill overtook her and instantly affected her. Before she realized it her balls were shrinking, but, something told her that she wasn't loosing any production of cum. It suggested that her balls would be smaller but she would still be able to cum just as much. What was this power?

Before she could further contemplate what was going on Vivian began to absorb this batch of cum as well, continuing her growth. Holy shit, Vivian was going to be a big woman~ Astrid felt her cheeks flush and cock throb even though she had just cum, she mewled softly inside Viv from the thought. Astrid thanked Marika for this in the back of her mind, thanked her for this opportunity and the ability to have fun like this with Vivian. When she looked back at her balls she noticed - with the little light she had - that they were about the size of cantaloupes now, still big but nowhere near what they were. Astrid knew now that her balls were smaller she would likely slip deeper into Vivian's pussy.
