Yello - Physical Exam : Stamina (Patreon)

After Yello was properly lubed up (she was literally dripping), the doctor and his assistant went on to assess her fitness and stamina. Her body and her orifices had to be in peak condition to continue working at the glider repair shop.  While the good doctor took care of Yello's vaginal entrance from behind, his assistant tested the flexibility of her mouth, also making sure she was still able to suppress her gag reflex as he shoved his engorged member down her throat. It was doubtful if she ever possessed such a reflex, but that would have to be examined another day.
