"Well, that's surprising." Her son remarked, as he made webs of saliva by rubbing his fingers together. "I thought for sure that you were against my fingers slipping into your ass at first, but now it seems like you're the one who wants it more than anyone else."
"Do you really want my finger up your ass that much, Abi, that you're willing to lick your father's hands clean like a dog?" He asked with a smirk on his face, while looking at his adorable daughter like a pervert.
She wanted to deny what he said and refuse all the allegations against her, but she didn't have the heart to do so since she actually really did want her son's finger up her butt.
After having her asshole being played with this whole while, to the point that she could feel it throbbing even now, and after having a taste of her anus, she had enough of all the teasing and wanted her son's thick finger inside her to show her a whole new experience she had never felt before.
