HENTAIED.com - THE NEW ASS-ISTANT (Jia Lissa, Veronica Leal) [2160p] 4K

The narrative begins in a laboratory known for bizarre sexual experiments, where a new assistant, Veronica Leal, joins the team. She is curious about the experiments and disregards the warnings from Jia, the lead scientist. After exhausting work on a potion to enhance size, Jia briefly leaves the lab, allowing Veronica to explore the parasites. Veronica, intrigued by the parasites' effects on pleasure, applies one to her neck despite Jia's prohibitions. This causes her to become overwhelmed with arousal, and the parasite grows significantly larger, traveling down her throat and releasing a stimulating fluid.

Upon returning, Jia discovers Veronica completely naked and in ecstasy, realizing that the laboratory is now at risk of being overrun by the tentacles created from her experiments. To protect herself, Jia positions Veronica to attract the approaching tentacles.

The tentacles begin to penetrate Veronica in multiple ways, filling her with pleasure and alien fluids. As the situation unfolds, Jia succumbs to the chaos and joins in, leading to a scene filled with intense sexual imagery and the release of fluids. Ultimately, Jia notices a complication and attempts to manage the situation, ensuring the escape of the parasite is thwarted, maintaining control over the events in the laboratory.
