Apparently that was just the beginning though, as Jen's mom suddenly begins to cry out as she is now desperately stroking her huge cock with both of her hands now. In the second Jen had looked away, her mother's cock had trippled in size, now over a foot long, and was now easily as thick as her wrist. Her balls were not left unchanged either, as the now softball sized orbs forced her legs apart, and her cock to stand up tall while she was laying down on the bed. Her mother began panting like a mad woman, as her sense of reasoning was slowly deminished, until all that was left was a sex driven nymphomaniac.
What neither of them knew (anymore that is) was that before he called Jen, Kyle had tried to call her house first, but had gotten her mother to answer the phone instead. Not wasting this opportunity, he cursed her to recieve triple the curses effect of the next person who she has sex with, that her cock will become so sensitive that unless it is inside of a pussy, it will feel like it is burning, to give him back the curse, and finally to forget the call had ever happened.
So that was why Jen's mother now had a cock and balls 3 times Jen's size. The sudden overload of hornyness had shocked her mind enough to throw her into a mental state where she would be highly impulsive until she was satisfied.
"It burns, it burns! Moaned Jens mother as she kept vigorously pumping her cock to no avail. The hightened sensitivity her cock had made it so that the cool air burned it. She needed to cover it in something, anything. And then she saw it. The perfect thing for her needs, all pink amd moist while nestled cutely between her daughters thighs. Using strength that neither she nor Jen realized she possessed, Jens mother lifted up her daughter and impailed her pussy onto her cock, sliding into her all the way until she reached the base of her shaft. Jen's body made room for the sudden intrusion, and Jen herself came instantly, not stopping until she couldn't slide further down anymore. All the while, her own cock was growing in size, reaching 16 inches in total.
Jen's mom then used her strength to twist her daughters body in ways that would have been dangerous if Jen hadn't been quite as flexible. However years of cheerleading and gymnastics before that had practically turned Jen into a contortionist, so she wasn't in any danger.
That being said, Jen's mom had forced Jen's legs to be fully tucked behind her, and crossing eachother. Her arms were secured behind her back too, and by her own panties no less. Jen's mother had removed them while she was getting fucked, and now had found a better use for them.
Jen's mother readjusted her daughter so that her head was tucked inbetween her boobs, and put her robe on, using the sash to secure Jen to her own body, with just her head sticking out of the top, and her cock poking through the bottom.
By now, Jen's mother's reasoning had returned to a relatively stable point again. "I'm so sorry sweetie" apologizedher mother. "If my cock leaves your pussy, it will definitely burn like crazy again. So until we can figure this out, I guess your going to have to get use to being my cock sheath."
Jen couldn't believe what she was hearing. Did her own mother really just make her into her personal cock sheath? Jen also was even more shocked by how much the thought of being just her mother's cock sheath turned her on. She would be feeling it cum gallons everyday inside of her. And since it was so huge, it actually extruded from her torso in a long mound. Even more so, was that her boobs were big enough that every timy movement would cause them to fub up against and bump the tip of the cock inside of her, causing it to cum even more often.
"Hey, don't worry though. I will still fuck people for you, by using your huge cock as if it were my own. How's that sound?" Suggested her mother. In response to the question, Jen's own cock became very erect and now stood fully erect, and now also poked out of the robe entirely, as the opening draped around it. Jen's mother smiled, taking that as a big yes.
Actually though, Jen never even heard the rest of the question. Her mother had shifted her self around and now her boobs were covering both of Jen's ears, effectively making any noise a garbled mess to her. The only 2 things she could "hear" was the sound of her mother's heart beating and the sloshing of breast milk inside of her breasts.
"Here, I have one last thing for you sweetie" says Jen's mother as she opens her closet and pulls out a box. Inside it are what look to be small suction cups with a shared tube comming out of either one. Meeting in the center at a T-joint with another short tube comming out of that. She attached the cups to both of her nipples and stuck the T-joint infront of Jen's mouth, forcing the shorter tube inside. "There now you can drink whenever you want to. Mama, has pleanty of milk to spare, so don't worry about being greedy." All jen could do was begin sucking, as a small flow of milk began to be siphoned out of her mother's boobs, and into her mouth.
