Cheeky high school girls are forked, threatened, licked and chewed up

Shiori-chan is a cheeky high school girl, and Yui-chan is the serious type. They're two cousins who get along well. Shiori-chan, who has nowhere else to go, is helping out at Yui-chan's house, and her uncle is hired as manager at a convenience store so she and Yui-chan take the opportunity to work there part-time.
At that part-time job, something happens that truly shocks Shiori-chan.

＂Hey old man, I said, what are you looking at＂

Shiori-chan shamelessly gives a cheeky complaint to the uncle, Yoshihiro, who keeps glancing up Yui-chan's skirt while they're sorting through goods.

Yoshihiro's patience is running thin, and he wants to punish the high school aged Shiori-chan just for being so impudent with him. Despite her cocky appearance, Shiori-chan is ignorant and naive, so tricking her is like taking candy from a baby.

＂It's up to you, either suck it or I'm going to the police＂

It's immediately effective on Shiori-chan, who's seriously aiming for a scholarship and trying to become independent. Yoshihiro, with his raging cock driven into her cheeky mouth, gets carried away in the pleasure of degrading his saucy high schooler niece.
