Derick sobbed between moans as the dick slowly grew in width and length, her pussy continuing to seal her fate despite her wishes. She felt the heavy balls churn and swell against her thighs, pulling the shorts taught as they swelled. Her stomach expanded at an increasing rate, she looked like a pregnant woman who was almost due, and quickly passing that milestone. She felt her cervix lock around the cock and she knew that getting it out was impossible, it would fill her vagina completely and pump her continuously full of semen. She couldnt see her crotch past her swollen stomach, now looking to be term with twins, but she could feel the balls straining her clothes to the limit, hot and gushing cum into her. She had given up, her hands reaching to her stomach as she moved her hands down the hot mass, feeling it spread her fingers as it grew. Her bellybuttom had popped out, and she moved her hands to her crotch. In the small part above it that wasnt a cum-filled balloon, she felt a hot shaft tight against her skin, pulsing away as it deposited its seen. She resigned herself to her fate and grabbed the shorts, forcing them around the balls with a scream of excatasy as they fell with a heavy slap to the floor, pushing her legs apart as they grew. She was now large enough to be overdue with octuplets as she resigned herself to her fate to be filled for the rest of her life. There was no way the dick inside her would come out, the head was twice the size of her entrace, she estimated. At least she wouldnt explode, the protein rich cum seemed to help accelerate her skin growing as her uterus swelled. Derick leaned into the floor and allowed herself to be over cum with pleasure, screaming and moaning as she grew.
