"You just stay put until we're finished with you, honey. We saw you take all that stuff and now we're going to find it." Try anything and I'll scream,..." Darlene pouts. She thinks of all the things she'd taken from the main floor of the department store. The bra that she'd stuffed down her jeans and the jewelry that she put into her purse when she thought no one was looking. We'll find it all. "I'm warning you," she exclaims. "I'll scream!" Go ahead and scream all you want. No one will hear you.. I felt two hot stinging blows land one right after another and almost immediately her other hand came around and pulled my now nearly stiff cock. “That’s it Daddy.

It was so wrong. And yet it felt so much better than any of the cheating I had ever done or even sex with my wife! I was ashamed and. . you know, ............. do it to ? We all need a little stimulation sometimes. She was lightly laughing as she walked out. Sure enough when she got home Sunday night, she came straight to my room with her night bag, opened it up and pulled out two pair of panties, tossed them on the bed and said enjoy and left.The next week was brutal, I could wait to get home everyday. I ran straight upstairs to my room and used Robins panties to get off. On thursday evening sis knocked on my door and came.

I can feel my pussy begin to throb and ache , and I can feel myself becoming increasingly wet .Just as I am about to cum from my efforts.
