After the last furious session of steamy sex, Amy and Mark both fell into a blissful state of slumber.
Upon awaking the next day Mark got up to take a shower. He made it all the way to the bathroom, got the hot water running and went to relieve himself while the water warmed up. It was only then, when he went to grab ahold of his member to take aim, did he remember what had transpired the night before.
"AHHH! What the??" It all came rushing back with perfect clarity. His need to urinate and the running shower all but forgotten Mark ran back to the bedroom to his still sleeping wife.
After a moments hesitation, he thought it best not to wake Amy just yet. Thinking she might become hysterical he wanted to see for himself the extent of the changes to his wife.
Amy was laying on her stomache so he carefully lifted her tail, and yes it was definatley now HER tail. He could discern no visible definition between where Amy finished and where the supposed sex toy started. It was as much a part of her now as Marks new cock and balls were a part of him.
To make matters worse, it looked as though the black and white fur of her tail was spreading across her beautiful round arse.
Looking underneath Amy's new appendage, Mark wasn't too surprised to see her genitalia was that of a cow. Glistening dark folds of flesh.
Despite the shock of what he was seeing,Mark still felt himself getting aroused by the sight and scent of Amy's proud bovine sex.
He was torn between his arousal and his desire to see to what extent his wife had changed. "No. Now is not the time for more sex. I need to know how bad this is!" He thought to himself.
As gently as he possibly could, Mark rolled Amy over onto her back. She stirred ever so slightly during the process, giving of low mooing moans.
With Amy now settled on her back and thankfully still asleep, Mark could see just how much this thing had spread. Amy now also sported a small pink mound of flesh below her stomach. There were four welts on the mound which as Mark watched, continued to grow.
"Yep. That would be an udder. Shit oh shit oh shit! What am I gonna do?" Mark said aloud, wincing immediately as Amy again stirred with a low moan.
The whole mound was About 10 inches around and portruded about 4 inches from Amys waistline. The welts had grown to an inch and half in length and stopped. Surrounding her udder and stretching upto her naval was a light dusting of soft white fur.
As much as Mark was distressed at seeing his wife in this predicament, he was also extremely turned on by it. His new weapon slowly emerging from his black and white furred sheath, Mark could control himself no longer.
Giving in to the beastial urges eminating from his new manhood, Mark lowered his head to Amy's little pink teats and delicatley began licking them one by one.
This in turn woke Amy from her slumber however she just lay there enjoying the sensations of her husbands tongue as it worked its way down to her moist lips.
"Ohhh, OHHH, mmmurrr. That feels sooo good baby. Don't stop doing that ever! Mmmmurrrr"
Mark, now fully erect, had no intentions of stopping yet however and he continued giving Amy a licking she wouldn't forget in a hurry. In and out, in and out, up and down the dark folds of her bovine womanhood.
"Mmmmoooooo! I need you in me now baby! I need you to fill me up right now!!"
To this end Mark was only too happy to oblige. Rolling Amy over and positioning his big bull meat at her gates of pleasure, Mark leaned over and whispered to her,
"Ready now my sweet? Here it comes!"
And with that he plunged his member deep into her dripping tunnel.
Harder and harder he pistoned into her sweet tender cow sex, all the while noticing with each thrust more of the soft, downy black and white fur spreading out from her thick tail.
In his sex crazed mind, it didn't even register with Mark that his rampant thrusting might be the catalyst of his wifes transformation.
"OOOOOHH MARK! BABY! Mooooooo! I'm COMOOOOING BABY! Don't stop! Don't stop! MOOOOOO!"
Hearing that sent Mark over the edge and he pumped his new bull ball bag deep within her.
Now both spent, the happy couple collapsed on the bed, exhausted.
Laying there in their blissful post coitus state, Mark with his arms around Amys waist, Amy whispered to her husband,
"Baby, that was amazing! What was that surprise you had last night?"
When she didn't get a response, she opened her eyes for the first time that morning. As she turned to look over her shoulder at Mark, She caught a glimpse of her belly.
It took a moment to register what she was looking at but when it finally sank in, all she could think to do was scream...
