Derick awoke to a terrifying sight; she was on the floor, with her hands caressing the balls of the large dick back inside her pussy. "Fuck, no!" She screamed, grabbing the balls and actually managing to pull it out this time. 'Must've gotten it before it can get too far in me.' Derick realized, throwing the throbbing male genitals on the floor. She felt her pussy contract and squeeze, almost like it was sad the pleasure was taken away again. "I'm not going to end up as some cum balloon!" She declared, turning away to consider where to dispose of the genitals.
Just then, she felt something wrap around her tanned calf, "What the?" She asked, looking behind. The grown dick was now slightly bigger, and was pulsating like blood was fiercely flowing through it's veins. "No fucking way!" Derick screamed in terror, realizing it's going to be harder to escape than ever before. The dick had it's shaft wrapped around Derick's shapely leg, twisting it's way up back toward her pussy. Almost like it could sense the dick coming back, Derick's pussy kept squeezing it's muscles, making Derick feel flustered. "Please stop." She begged, crawling along the ground, trying to shake the dick off the whole time.
The lengthy junk had managed to reach Derick's vagina once again, and slipped in with a wet sound. "Aah, no!" She cried, feeling the dick fill her pussy with it's girth once again. Her pussy seemed to be happy its companion was back, and began the usual squeezing and milking of the dick. However, the dick wasted no time, and penetrated Derick's cervix again; her pussy then locked up tightly, ensuring there was no way the dick was ever coming back out again.
Utilizing it's newfound muscle control, the dick managed to contract and expand it's shaft, resulting in a feeling of makeshift thrusting. It was no longer just penetrating Derick, it was now having actual sex with her. In a matter of minutes, the thrusting Dick had started cumming again, filling Derick back up with the warm semen she had grown to both love and detest. Her belly had already reached the size of a basketball, and was slowly expanding from the amounts of semen being released in her womb. "Dear god; what have I done?!" She asked herself, as she arched her back in pleasure.
