She slides the object up your insides.

She braces the back of the phallus sticking out of your pussy against her shoulder and adjusts her grip. Stars explode before your eyes as she shifts her body weight forward. The tool plunges deeper inside your womanhood. She twists the shaft carefully to assist in easing its path causing intense friction with your vagina's muscled ring.

Through the fog of your mind you attempt to focus on what is happening between your legs. The tool isn't even a quarter inside of you, but you have never felt so full!

You cum again!

"Aarrarrrrgh..." You grit your teeth and endure your breached sphincter spasm around the tool's girth.

The technician leans in closely to your pussy to assess the tightness of seal between you and the tool.
