She's moaning, crying out with each one of his thrusts into her. "Fuck," I hear her say in accented English, "you fucking do that one more time and I'...l cum all over your cock." "You cum all over my cock and I'll cum up in your cunt." "I already drank all your cum. You filled my belly as I swallowed every last drop. You've got none left inside you." "Want to bet?" "Ok. Fill me to the brim with cum and I will be your slave for 24 hours. Fail..." She pauses and I imagine her smirking wickedly.. With my rear view of the couple I could not see their faces, but could see my father’s balls slap against Heidi’s cunt lips and catch glimpses of her big tits with hard nipples , pressed and rubbing rhythmically Dad’s muscular, hairy chest. Her long shapely legs were wrapped around his trim heaving back , pulling him deeper and deeper into her, and I could see the muscles of her legs flex as she pulled herself up to meet each of his powerful thrusts and urgently grind her dark haired pubic. Dad could have gone shoppingwith her and I started to regret the distance which had grown between usover the years. It wasn't the usual Dad thing but I could have done thiswith Alexi. I had missed years of her life. I started getting a littlemisty eyed. Alexi had started talking about something while I wasabsorbed in thought, when she noticed my troubled face. She held my handtighter. "Mom, what's the matter?"I stopped in the middle of the mall and tried to compose myself. I wasgetting. He told me to swallow it all like a good little girl and I did, just before the video faded out.Damn. Damn. Damn.I remembered that night well. Billy had driven me up to Lookout Mountain, which had long been the local necking spot because of the romantic view of the city. I thought we were going to have some hot backseat sex, but Billy begged me to blow him. Not that I minded. There's something about hot sticky sperm splashing around my lips that I've always loved. I remembered Billy had.
