She changes

Johanna felt her words and sense of self begin to disintegrate as the old man constantly abused her. With each new humiliation, the word 'slut' on her collar burned ever deeper into her mind, carving out a space for her new identity and purpose.

Her body slowly adapted to the daily degradation, her nipples hardening in anticipation of his thick cum whenever she donned her slut collar. She craved it, longing to taste him inside her mouth, imagining how much bigger he would feel when buried deep inside her craving cunt.

She found herself shamelessly displaying herself to men around her, wanting them to grab and experience the fullness of her ample breasts. And all the while reveling in the euphoria spurred by daily injections of an unknown medicine that served as a **** more potent than any other.
