She never planned on it happening. One hot afternoon after the kids left for college, the big mutt they called Rex started sniffing around her legs while she was in nothing but a thin robe. His nose pushed right up under the hem, wet and insistent, and instead of pushing him away she spread her thighs a little wider on the couch. That was the first time. His tongue was rough and hot, lapping straight at her cunt like he knew exactly what she needed. She came hard, legs shaking, robe open, and the sound that came out of her mouth was low and filthy. After that she stopped wearing panties around the house.
Every day became the same dirty routine. Shed get home from work, lock the door, drop her skirt, and call him over. Rex would bury his muzzle between her legs and eat her like he was starving. Shed grab his ears, grind against his tongue, and talk to him the whole time. Thats it, boy, lick Mommys wet pussy. Fuck, your tongue feels so good. Her juices would drip down his chin and onto the floor. When she was dripping and open shed get on all fours, ass up, and reach back to guide his cock. It was thick, red, and already leaking when it slid into her. The first thrust always made her gasp. He fucked like an animal, fast and deep, knot swelling until it locked inside her. Shed come again and again while he pumped hot cum deep in her cunt, her face pressed to the carpet, moaning his name.
She started filming it on her phone. Little clips of her spreading her lips for him, of his knot stretching her, of the thick strings of cum that leaked out afterward. Watching the videos later made her wet all over again. Sometimes shed play one on the TV while he mounted her a second time, the sound of her own moans mixing with the real thing happening right then. Her body learned to crave the stretch, the heat, the way his cum stayed inside her for hours. She stopped caring about anything else. The house could be a mess, the laundry could pile up, all she wanted was his cock and his tongue.
One night she let him take her on the kitchen table. She lay back, legs wide, and he mounted from the front, cock sliding straight into her soaked hole. Every thrust rocked the table. She reached down and rubbed her clit while he fucked her, whispering the dirtiest things she could think of. Fill me up, Rex. Breed Mommys cunt. I want every drop. When his knot popped in she screamed and came so hard she saw white. He stayed locked for twenty minutes, pulsing inside her, and she just lay there petting his head, telling him what a good boy he was.
She never told anyone. The secret stayed between her and the dog. Every evening after dark shed strip, get on her knees or her back or all fours, and let him use her however he wanted. The more she gave him, the more she wanted. Her body belonged to that thick red cock and that rough tongue, and she stopped pretending she was ever going back to normal sex. This was her life now, raw and filthy and exactly what she needed.
