She takes too long to decide.

Rose though is unable to think of anything to say in her defense, and that just leaves her open for the taking.

"Too slow whore!" The man yells, startling her, and he grabs her legs and pulls her down towards him. Rose starts to struggle and grip the threadbare sheets, trying to stop her movement but is unable. The man seeing her try is quick to switch his grip and holds both of her legs with one hand, the other going for his wand. "I warned you, whore!" A quick wave and her clothes melt off of her, leaving her bare and taking the last defense she had against the man.

"No! Dear Merlin, please don't do this!" She tried to plead to the man, only for his free hand to swat her pussy hard. She shrieked at the feel.

"Shut up, whore! You decided on taking the hard way and the hard way is what you're going to get!" He told Rose. She could only look down in blushing humiliation at the man between her now spread legs, his cock preparing to unknowingly take her purity.
