Giantess Insertion. [WM]

Astrid's mind was dulled due to all the pleasure she had been feeling, she didn't have enough brainpower to realize what was about to happen to her. That is, until she looked up. She stared with surprise and arousal as Vivian's massive lower lips descended above her. Viv was going to... Before she could give it any thought her world was enveloped. In a quick few moments she was surrounded with soft flesh, warmth, moisture, and the occasional spasm of the Seraphim's pussy as her upper body was slowly pushed inside her. She could hear and feel her silver-haired friend moan as she was inserted inside. "Wha... What the fuc" She tried to say.

It was tight inside Vivi's pussy, she could barely move. But, she wiggled around as much as she could anyway. Partly from surprise and partly because she knew it would make Vivian feel good. Astrid was pushed further into her pussy as Vivian lowered herself toward the ground. This caused her cock to uncontrollably throb between her breasts, and Vivian squirted femcum all over her and around her, spraying the ground due to her bodies insertion. Once the Sylvan was almost completely inserted she couldn't move at all and it was nothing but darkness expect for a small amount of light which showed her pink flesh prison. Though, she wasn't sure you'd call it a prison if you wanted to be there...

After they sat there for a few seconds of both their bodies convulsing, Vivian squirted a second time drenching the street below them even further and causing femcum to rush past Astrid and soak her completely. The idea of Vivian cumming from Astrid's body being inserted into her pussy was incredibly hot~ She bit her lower lip and panted inside the giantess's pussy. The air smelled of Viv, and her arousal. "You... have to... m-move me in... and out!" Astrid tried to shout, tried to tell her giantess lover to thrust her body in and out of her flower. If she was honest with herself though, she might cum as soon as any sort of motion started. She was already on edge...

As if trying to encourage Vivian to thrust her body in and out of her lower lips Astrid began to wriggle and bounce around as much as she could, trying to thrust herself in and out. She... wanted to make Vivian feel good. And even if this was a bit claustrophobic, she was absolutely loving the entire situation and wanted to take it further. If she could she would use her hands to rub the pink walls around her, but, her arms were pinned to her sides. She was a hair trigger away from ejaculation... Wait, if she came now... would Vivian grow with Astrid inside her? Also, Astrid would be stuck in Vivian with... all her own cum. The idea should probably scare her, but... it didn't. It exited her.
