Even though Diane is out cold, her penis is still fired up from the curse. By the time Diane's boner broke her shorts, it was a little over 3". Not big to everyone's standards, but not to the passed-out tomboy. While Diane is having a dreamless sleep on the couch, her little weenie has been plumping up to be a proper hot dog.
Throughout the night, the growth continued. If Diane was awake, she would've been poking and playing with her newest member. Maybe she would get herself hard and come into her hand to see how she would taste like. Unfortunately, Diane is still unconscious of her surroundings and as such wouldn't be interacting with her newest plaything until she wakes up.
By around midnight, Diane had grown another 3" making her about average to men around the globe in size. At around this point, Diane has regained enough consciousness to be aware of her surrounding but is still out of it that she still doesn't notice her broken shorts or her 6" shaft where her pussy was. What Diane did notice was that she was cold and that she grabbed her sports blanket off of the couch and bundled up inside it. A little while later, Diane's parents had made it back home after their social gathering.
What they saw when they opened the front door was that not only the lights were on and the TV was still playing, but their daughter was sleeping on the couch instead of being in her bed. The mother was about to wake up their daughter and pull off the blanket for leaving everything on, but the dad held her back. He told her that Diane must've been tired after seeing her favorite team win the game and celebrate a little too hard. The parents agree to deal with the punishment in the morning but for now, everyone is going to their own bed.
Being as careful as he could, Diane's dad carried his daughter to her bedroom, making sure that the blanket was still tucked in on her. Not once did her father notice Diane's now 7 1/2" package nestled underneath the cotton fabric. Diane's dad had gracefully placed his only child on her bed, whispered to her good night, and closed the door behind him when he left the room.
As time moves forward toward dawn, Diane's brain has been flooded with erotic dreams while her penis has been filling up with more mass. While Diane has been dreaming about her beloved sports teams, both the sports stars and their cheerleaders, she also had dreams about Chastity. During her wet dreams, Diane's dick has been very busy to keep on growing. As the inches start to pile up, the more erotic the wet dreams become, with Chastity being the focus of the dreams.
By the time the sun has passed over the horizon, Diane has a literal foot-long hot dog out of her shorts. The 12" morning wood has risen up through the blanket to grace the sky with its girthy mass and its matching tennis ball-sized testicles. The final dream that Diane had before being rudely awakened was about Chastity and her fucking each other with a strap-on. When Diane came in Chastity in the dream, the real-life Diane came as well. The blast from her phallic cannon has not only blown away the blanket but has also blasted its cum at its owner's face, giving Diane a surprise facial.
By the time Diane has wiped away the cream from her face, she has finally become fully cognitive of her surroundings. Diane became aware that something was wrong and it wasn't because she was now in her bedroom. Looking down at herself, Diane could see that not only she was damp and sticky from the cums that glaze her, but also that she is now one foot bigger where it count. Realizing that the baby dick from last night has evolved into a prize-winning rooster, the only thing to do for the teenager is scream.
