As big as her cup size

Her thumb rubs on your cock head. “Do you think men would act differently if women knew their dick size? Men treat me differently when I dress to show off my breasts size.”

Her hand on your dick, you ask what you want to know, “How big are your tits?”

She laughs, “Let me find out your dick size and I’ll tell you. And if your dick if big enough, I’ll show you.”

You pray you’re bigger than your little brother. The feel of her soft tits and her stroking hand get you hard.
