A chubby lady of around 60 served me, she said "There isn't anything round here to eat", shame I said in a flirty way, which made her blush. "You coul... try further into town if you want", I said "It's fine I've only got an hour", she said "I have a dinner hour in ten minutes", which I thought what an unusual thing to say, smiling I told her I was right outside.Fifteen minutes later she came out and tapped on my window, as I opened it she said "I usually eat my lunch upstairs in the locker. It’s obvious to her that he has his hands full with the child screaming for sweets, biscuits, you name it. Meanwhile, Grandpa is working his way around, saying in a controlled voice “Easy William, we won’t be long ... easy, boy”.Another outburst and she hears the grandpa calmly say “It’s okay, William, just a couple more minutes and we’ll be out of here. Hang in there, boy”.At the checkout, the little terror is throwing items out of the cart and Grandpa says again in a controlled voice. "Oh!" Katrina giggled softly, peeking from behind me. "That's a pretty picture." Having a nice talk, Slave-Sister?" I grinned at Cheryl and she grinned back at me."He's still apologizing," Cheryl grabbed Jim by the hair, lifting his head. "Aren't you, slut?" Yes, Mistress Cheryl," my brother replied breathlessly and he turned his head to look at me. He was quite pink and his handsome face was shiny and wet."Looks like he's been apologizing for awhile," I chuckled. "Did you cum, Slave-Brother?". Then I let it slide down my arms and on to the floor. Looking imploringly at Curtis, hoping for some kind of reaction, I hesitated momentarily at the skirt. When Curtis continued to sit there impassively and say nothing, I began to undo the clasp and zipper on the back of my skirt. Wiggling my hips slightly I worked the skirt down and off my legs and it puddle around my ankles. Turning to face Curtis, my hands self-consciously moved to cover my panties and bra. Shoring up my courage, my shaking.
