At this stage, he knows I'll do anything. This isn't my first time undressing on his front porch. I step out of my shorts, checking the road for traf...fic. Then my panties. I wear them when I come out here, even though Sam would tear them off me if I wore them inside. They're for later. My top comes off next, then my sneaks. Sometimes I leave them on, but not today. Still no cars. Good. I begin to relax just a little as I knock again. "Give me a minute." It's ten minutes, at least. Three. I then set up a weight lifting bench and raised where you put the barbell on its holder to its highest setting I fastened ankle cuffs on each side to except my legs and secure them. Then I got too large wide leather belts from the Salvation Army store that will go one around my pelvis area just above my cunt the other around above my tits and below my armpits so I will be secured to the bench and could not get up. Next I secured a ring in the floor with a chain that would go to to handcuffs. She leaned forward as she stuck her tongue out, and started licking from Joanna's cunt up past her asshole. After licking the cum dripping out, she looked up at Grandma."Stick your tongue in deep and clean her out good," Grandma ordered. Jessica complied, swirling her tongue around inside her sister's asshole. Once she got past the disturbing concept, and the sweaty, musky smell, Jessica began to get turned on, too. She kept going until Joann had another orgasm. Jessica was dripping wet by that. Wow! It doesn't sound like much that way, but what if I told you that my daddy has his big dick all the way up my pussy and he's about to shoot a gallon of cum in me? Doesn't that sound like more fun?"It sounded like fun to me. Unbelievably, my prick swelled some more. Don't know how it could, but I could swear it felt twice as big as before. I knew Marcie shouldn't be telling anybody this, but it also turned me on for her to be bragging about it to her girl friend. Sue simply watched silently.
