Sarah had been thinking about it for months. Her husband worked late most nights, leaving her alone in the big house with nothing but her thoughts and their big, friendly German Shepherd, Rex. Shed seen videos onlineraw clips of women on all fours, taking thick, red dog cock deep while they moaned like whores. It made her pussy drip every time. Tonight she decided to stop fantasizing.
She stripped in the living room, letting her big tits swing free and spreading her shaved cunt lips so Rex could get the scent. Come here, boy, she said, voice already husky. Rex padded over, tail wagging, nose going straight between her legs. His rough tongue dragged over her clit in one long, hot lick. Sarah groaned and dropped to her hands and knees on the rug.
Fuck, thats it. Lick my married pussy. Rex kept lapping, slobber mixing with her juices. Her nipples brushed the floor with every shiver. When she reached back and spread her ass cheeks, Rex mounted without hesitation. His furry belly covered her back. She felt the hot, pointed tip of his cock jabbing against her thigh, then her ass, then finally sliding through her soaked folds.
The first push inside made her gasp. Dog cock was hotter and slicker than any mans. It jabbed deep on the second thrust, stretching her in a way that burned so good. Oh my fucking God, its in me, she panted. Rexs hips jackhammered, driving the swelling shaft in and out with wet, obscene sounds. Every thrust slapped his furry balls against her clit.
Sarah pushed back, meeting every stroke.
Harder, boy. Give me that dog cock. Fuck your bitch. The knot started to swell at the base, bumping against her entrance, demanding to be inside. She reached back and spread herself wider. Do it. Knot me. With a hard shove the thick bulb popped past her lips and locked inside. Sarah screamed in pleasure as the knot stretched her open and began to pulse.
Rex kept thrusting in short, frantic strokes while his cock jerked and pumped hot cum straight into her womb. The pressure of the knot and the flood of dog seed pushed her over the edge. She came hard, cunt clenching around the throbbing knot, juices squirting down her thighs. Rex stayed locked, filling her until she felt bloated and used.
When the knot finally shrank enough to slip free, a thick gush of cum poured out of her stretched hole. Sarah stayed on all fours, panting, watching the mess drip onto the rug. Her pussy felt wrecked and perfect at the same time. She reached back, scooped some of the cum onto her fingers, and licked it off with a filthy moan.
Rex circled and licked her clean, his tongue pushing more cum out with every swipe. Sarah knew this was only the first time. Already she was thinking about tomorrow night, and the night after, and how many loads of dog cock her married cunt could take before her husband came home. She smiled, still on her knees, already wet again.
