Over The Top Reaction

"But hold up now..." I said after realising that I was missing a crucial piece of information in the picture. "I get whatever you said up until now, but none of that still explains why you want to make me cum so much."

"T-That...That..." My mother stuttered as she looked away, unable to say the reason she wanted to make me finish so quickly. "T-That's a secret, Kafi! An adult's secret!...So, a child like you shouldn't bother to think about that since it's an adult's business!"

She brought out the grown-up card, as she was unable to find a suitable reason for tugging me off, which made me roll my eyes. 

I also didn't bother trying to make her explain since I didn't really care too much, and even suggested a way to help her out since she seemed so desperate and I personally wanted to play with her a little.
