The doctor had his arm around my mother shoulder and this hand was gently toying with her nipple. My mother was like putty in his hands, her miniskirt...having ridden up her legs to reveal her bald cunt. "Ah there's my little Daisy, doesn't she look beautiful girls?" My mother looked at the speechless for a moment whilst my sisters giggled. "I knew it, a mother knows these things, I knew it" she finally blurted out. "Dr I knew from an early age that David.'s............. I mean Daisy was a girl,. " I whined. Needing him to start moving, to take me properly. Heinz rocked his hips back and withdrew until only the head was within me. Driving back into me he began a steady rhythm and I came. I came so hard the cum spurted up between us and hit my face, the pillow, and all points between. The release was tremendous, and as my prostate contracted, sending my sperm flying out of me, my anus squeezed Heinz tightly causing him to grind deeply within me. I could feel him buried deeply. I reached. I have ‘who let the dogs out’ on the stereo, of course.I feel his dick throbbing inside my shithole, and I hear his growls grow louder. I cry out and breath against the tiled floor, pathetic sounds coming from my whore-mouth.“Oh fuck me! Make me come!” I scream. I think I’m losing my mind. Hell, I know I’ve lost mind. I’m a dog-fucking whore, and I should be ashamed that I’m getting anally fucked by a canine, but I’m not. I love it. I feel. Wrenching orgasm after orgasm from you. Some time later, the battery on the vibrator is dying. You are crying, not sure if it's from pleasure or pain. "Mercy," you croak. Your legs and hips tired and getting sore, your pussy spasming, either rejecting anymore contact or begging to never be left empty. I put the vibrator to the side and climb between your legs, supporting myself on my elbows, I cradle your face in my hands. Kissing you gently, I kiss your mouth, cheeks, and nose."No more," you.
