Bast's laughs are choked off by the tentacles, her eyes widening as tentacles stuff themselves into her mouth and painfully squeeze her tits. She lets out a loud yowl and starts slapping Phorsaal's ass. Then, she grabs her dick... And does something strange.
First, her dick get longer and longer, till it's scraping across the floor. Then, it gets soft enough for her to push and pull it where she wants. After that, she grabs Phorsaal's dick... And immediately rams it into Phorsaal's pussy. Then, it suddenly starts pumping itself in and out. Basically, she was fucking herself! The pussy tentacle she had been fucking earlier disappears into the floor, before another one pops up and worms into her ass besides Bast's cock, similar to hers.
