Her tongue played with the dog's piss slit for several seconds, delving inside the narrow opening for more jizz. She jolted the animal's nerves again and again, and soon the animal was whining and licking his lips. After calming the dog with her gentle hands, she decided it was time to get serious.

Ruth opened her mouth wide and wrapped her greedy lips around the dog's cock head. Then she immediately moved her lips down his cock shaft, all the way to his hairy balls. She gobbled up his cock in no time, making it disappear deep within her mouth.

"Mmmmffff!" she mumbled, her mouth stuffed with hot doggie prick. Her tits hung down heavily as she leaned under the dog and sucked his cock.

She bobbed her head back and forth, gobbling on his prick greedily. She sucked his cock deep down her throat, spit it halfway out, then swallowed it again.

Her clinging lips massaged the entire length of the animal's prick shaft, from his hairy balls to his greasy prick head and back again. She excited every bump and every vein, until the bumps began tingling and the veins began gushing with boiling blood. The prick grew fatter and redder, and soon was throbbing against the roof of her mouth.

But she wasn't quite satisfied. She wanted this Saint Bernard's cock as hard and as big as she could get it. So she pumped some more, working her wet lips up and down his mighty cock shaft with blinding speed.

Spit oozed from the corners of her mouth and dripped onto her tits. Cum trickled down her throat. She snorted dog hairs out of her nostrils.

The prick head speared the back of her throat, drove her cheeks outward, and caressed the roof of her mouth. She choked and gagged repeatedly, but never stopped sucking. She knew that the cock would be plenty big enough to fuck before long.

With bugged-out eyes and puffed-up lips, Ruth Ann sucked on the dog's cock. She greased his cock down with her spit and made it all shiny. She stroked the cock with her clinging lips and made the fucker swell up to a gigantic size. When she finally spit the cunt-stabber out of her mouth, she knew that it was ripe for fucking.
