Alex stood up rubbing his butt, "I don't know what came over him. Benny was suddenly growling and pounced on me."
"Was it fun dear, asked the misses with a smirk."
"I feel violated, my butt was not made for such as he put in. Oww I can almost feel the sensation yet."
Benny seemed pleased and laid down with a nylabone to work off stress.
Alex and the Misses' went to bed late after much conversation as what to do about Benny.
Alex was asleep and heard moaning. Turning toward the sound he saw in dim light Benny strectched out over his wife. She was still somehow asleep, yet Benny was hell bent on having sex missionary style.
Alex started to rebuke the animal, but Benny had other ideas and snarled at Alex. Sitting up Alex tried to call his wife awake, but the was sound asleep. The mating went on for over and hour as Alex watched helpless to stop the 180 pound dog.
As Benny squirmed in and out Alex saw the wife's ears. Looking close as Benny growled her ears were pointed and getting furred. Evan as Benny pleasured himself Alex watch more changes to the wife.
Thick shag fur sprouted all over her body, legs and arms, as Benny kept humping away. Her eyes changed color to bright blue as her nose turned leathery and black.
Wrists and hands took on a forepaw look as her feet changed also.
Suddenly she started to scream awakening to see Benny engroused in sexual delight. Lifting her right leg as to kick Benny off she missed and the dog ended up humping her backside.
"Help me damn it, Alex your dog is fucking me, Oh dear he just came. I can feel his hot semen shoot into me!" The wife as yet did not notice or become aware of her form.
Crawling up to all fours gave the dog new interest and he surged all the faster, deeper, and harder. Alex's wife started moaning as the sensual delight of Benny's foot log cock did it's work.
Alex helpless and watching started to say, Is it fun dear, but what came out of his mouth sounded like low toned growl.
Alex suddenly aware of his body took a good look. He too was covered in thick fur. Arms were forelegs as hands forepaws. Legs were definate dog legs and hind paws. Rolling to one side he bent his now long neck around and enjoyed licking his sheath.
The personal please of licking what he never could before was most delightful. Even as the Misses' was being raped and changed to dog Alex was in doggy heaven.
As Benny finally pulled free, Alex now mostly Malmute himself sniffed his wife's rump. Animal desire was so strong that in a second Alex' was hard and straight out. Mounting his changing wife he now humped away as Benny just finished.
"Who the Hell are you, screamed the woman now half bitch." As she looked to her rear a furry tail came into view, her tail! Seeing Benny hard at work cleaning his cock and sheath, the other dog must be Alex.
