1000 stones!!!!
At my urging, the girls start browsing the shop with the help of the owner. it takes a bit, but after fifteen minutes the girls act as if nothing ever happened and are laughing happily while comparing clothes. I follow them closely with my eyes and notice that Katie hasn't chosen anything for herself, so I walk behind her and whisper in her ear.
"If we go home and there are not at least three pieces of clothing for you on the bag, I will fuck you four times in the ass, twice as hard as yesterday…"
Katie freezes at my words, then whispers back.
"Y-yes, master…"
"Attagirl!", I say, and pat her ass before moving back to my observing spot.
Finally, both girls have an armful of clothing chosen to try. As Mrs. Simpson guides them to the dressing room, Katie whispers something in her ear. Mrs. Simpson turns to look at me, then smiles at Katie and keeps walking. Curious…
Soon, she is back and heads straight to me.
