Jen hung from her mothers cock, her feet grazing the ground. Though the head of the horse cock had penetrated her the entire shaft was left untouched. The sensation was mind blowing for Jen. With each pound she felt her mothers desire to reach deeper with the body length cock, as did Jennifer wish to be filled with its pleasure.
Her mother continued to raveng her body as she invoked her new powers. "Transform myself: I want to become a living condom, compleatly hollow within but still sentient. My body will stretch as though it was rubber but be as soft as flesh and maintain structure even without bones"
She felt a warmth wash over her body and soon she felt the changes start. With each of her mothers thrust she felt the hot horse cock plunge deeper into her inch by inch. "Mother! I order you not to cum untill I say so!" She shouted. Her mother bit her lower lip, forced to endure the command, she continued to fuck Jen.
Jen looked below herself, seeing her pussy spread wide and dripping with juices. She noticed a slight bulge in her stomach, she also felt it too. It inched further up her body with each thrust, soon entering her chest. The buldge of her mothers fat cock spread her breasts apart slightly as it's head passed into her neck when she invoked her power again " dare myself: ill hold my mouth shut after I give my mother the order."
She felt her mothers horse cock head reach into her own, locking her head in place with its curve as it fucked the empty cavity of her brain. The sensation was unmatched, being so empty and full at the same time but most of all being used. Jen basked in the hot pounding bliss before she shouted "I order you to cum!"
On the spot Jen felt the hot surge of spunk rush up her mothers shaft within her and erupt into her head causing her face to explode forward with the blast. Thrust after thrust filled her head like a water balloon with cum, her neck acting like a pinch keeping it from draining into her body.
Soon her head was the size of a bean-bag-chair resting on the ground. She waved her hand behind her signaling her mother to pull out. Jen's mom griped her by the waist and began to pull Jen off her shaft. With a wet slop she popped her doughter off.
Jen planted herself on her feet bent over still resting her head on the ground. She gripped her oversized head in her hands and lifted it upright standing straight up. The displaced cum sloshed about her hollow rubber body, som cought in her boobs making them stretch down her body, some in her stomach giving her a pot belly that spread her sagging tits, some cought in her ass cheeks causing them to swell and sag as well, and most collected in her feet and legs. Her feet appearing fat and bulbous and giving her fat cankles.
She walked behind her mother holding her soft liquid stomach as though it was an unborn child, each step sloshing her body about. She gave a hard slap to her mothers ass "that's my mom! Good work girl!" The slap caused her to shoot a thick string of cum from her still hard cock.
