Her body bucked and writhed as she woke in her dark cell. It was hard to sleep more than an hour at a time, as the sex screams and involuntary orgasms constantly interrupted her rest. As usual, she was thirsty from dehydration and needed to change the sheets beneath her--they were completely soaked with her juices. Because there were no windows, she had no idea what time it was.

She struggled to get up from the mat on the floor. The added weight in her breasts and ass made her unsteady. She imagined she had gone up by at least four cup sizes and fifteen inches in her ass since her abduction. It seemed that every time she got used to her new proportions, another growth spurt would hit, and she would struggle to find her balance again.

As she changed the sheets, the door swung open. It was him. She hated everything about him--from his cruel face to his overly muscular body. Every sight of him ignited pure hatred in her heart.

But it also inflamed her pussy. Just the sight of him caused involuntary contractions deep inside her. She wondered if he would fuck her this time or if she would have to listen to him fucking one of the other captives in the cells she assumed surrounded hers.

This time, she was not lucky enough to take his massive cock. It remained covered in his shorts as he pinned her against the wall and injected her with the demonic medicine that continued to transform her into his perfect sex toy.

The flood of hormones overwhelmed her mind. It felt like a thousand orgasms at once while simultaneously creating an unbearable, aching desire for penetration. Often after an injection, she would bury her entire fist in her pussy while shoving the fingers of her other hand as deep down her throat as she could reach. She had no idea how long she fucked herself, but it must have been hours at a time. The only thing that would stop her was when the captor finally came in and pounded her. Only then could she have a few hours of sleep that came from the deep satisfaction of his twelve-inch, wrist-thick monster. Only then could she rest for a few hours before the relentless hunger in her pussy woke her again.
