Jenny felt very excited she couldn't control herself.What was in that pitcher she drank from?Jenny removed her undergarments leaving her sexy nude body exposed
to the empty room.Jenny laid stomach first on the bed grinding her groin into the sheets in mad heat."What's happening to me!I could mate with anything that comes
through that door!"Jenny screamed in mad lust her flushed nude form starting to glisten with sweat.Then as if to answer her cries Cynthia walked in with a large
Doberman dog on a leash.Jenny was embarrassed,but couldn't stop grinding her inflamed sex into the sheets."I'm sorry about this,but my uncle is a genius and he
needs these experiments."Cynthia told Jenny with regret in her eyes."IF you don't mate you will soon return to normal.Just fight the urges,because if you don't
something far worse will happen to your body besides uncontrollable lust."Cynthia said as she unleashed the dog and left the room locking the door."Wait help
me!I can't control my burning need to mate!"Jenny cried but nobody answered.Jenny looked at the large Doberman looking at her,and shuttered at the thought of
them mating.She was a high class woman behaving like a wild animal in heat."Maybe if she pleasured herself it would go away," Jenny thought to herself as she slid
her fingers into her wettening sex.Jenny orgasmed several times,but each time she became more excited.Soon the dog was licking her wet hole as she bucked in
pleasure.Jenny wanted more,and couldn't fight the need to go to all fours.Jenny watched herself being mounted on top of the bed in the mirror over the dresser.She
stared at the pitcher at the base of the mirror,and wished she had never drank from it.Jenny felt herself being entered by the dog,and remembered what Cynthia
had said about something far worse happening if she mated.Jenny was in blind lust she watched her breasts sway with each thrust from the Doberman.Watching
her womanly figure in the mirror being violated by the dog was too much.Jenny closed her eyes as the smells of her sex and the animal drove her to ectasy.After
awhile the male dog was finished and Jenny relaxed waiting for the two to uncouple.The waiting took too long,and Jenny fell asleep exhausted from her
performance.
