As Jen came back ther her senesces she saw her fat saggy breasts resting upon her pregnant belly (it is filled with spunk after all, it's the same thing) fat sagging ass and bulbous feet she decided she wanted to experiment with her old body as a condom.
She commanded her mother to get up and come to her. Her mother lifted off the ground and began jacking off in the direction of Jen. "Not like that you perv! Come over her" Jen yelled at her then pointed to the ground beside her. "Ok mom, I want you to grab my ankles and when I count to three your going to flip me upside down."
Her mother did as she was told and grabed her feet. Jen counted "ok. 1...2...3!" As her body flipped upside down Jen held her mouth open. As gravity shifted inside her the hot used cum from her mother drained out of her mouth like a waterfall from within her body, spilling out on top of her mother's horse cock.
After a minuet or so the last drop of cum dripped out onto the ground. "Ok mom, you can put me down now" she commanded.
Jen was now back to her original, beautiful self, while still being a living condom.
"Well, what should I do now with all my power?" she pondered to her mother.
