Alex was enjoying his day playing video games. He had been so busy with his school courses over the past few months that his favorite past time had taken a backseat in his life. As the next round of multiplayer began to load, Alex was startled by a scream from upstairs. Bolting to his feet, Alex began to make his way upstairs before he was met by his mother. "Honey! There are goats in your sister's room!"
Not believing his mother, Alex sprinted upstairs. Sure enough, he was met with the sight of two goats. Liquid stains around the room made it clear what both animals had been up to. Not wanting the goats to get into the rest of the house, Alex closed the door before heading back downstairs to join his mother.
"- yes that's right, goats. How soon can you come? That would be lovely. Thank you so much!" Kate finished as Alex entered the kitchen.
"Who was that?" asked Alex.
"Oh just the local zoo. I've been calling around the neighbourhood to see where the goats came from. It turns out they're from the zoo. I suppose they need to keep better control of their animals. Imagine that huh." Kate finished with a smile. "Anyway, no sense in wasting the day away. I've got some cleaning to do." Alex nodded in agreement as his mother went off to continue her cleaning.
Alex went back to his game, with the sound of vacuuming and his mother's signing in the background. The vacuuming got closer and closer before Kate entered the room. "Alright honey, time to take a break. I need to clean this room. You too Lucy." Kate gestured to her son and the family dog lying beside him.
"Fine mom" Alex relinquished his controller with a sigh. "Come on Lucy, let's go for a walk."
Lucy began following her owner before she stopped partway. Something seemed to be distracting the animal.
"Thanks Alex!" Kate beamed at her son as he went out with the dog.

A short time later, Alex and Lucy returned to find Kate lounging on the couch. "Any word from the zoo?"
"Nothing yet. You know it's strange. I really thought they'd be here right away. Anyway, our two guests seem to be doing fine, so no harm."
Alex plopped down next to his mother as the two settled in to wait for the zoo. He was browsing his phone when he noticed something odd. Normally Lucy would be quite relaxed after her walk. That was not the case right now. The dog was wandering around the house, sniffing excitedly. Alex put it off to the dog finally catching the whiff of the goats upstairs. Lucy's nose did not take her upstairs, however, but instead to Alex's mom.
Kate was absentmindedly reading a magazine when Lucy began sniffing at her pant leg. "Oh Lucy, who's my girl! Happy to see me. Good girl! Oh my Lucy!" Kate gasped as Lucy stuck her nose into the crotch of the woman's pants.
Kate pushed her dog away and moved to the other side of Alex. Lucy did not relent, however, as she quickly moved to follow Kate. The dog continued to sniff at Kate's pants, this time aiming directly for the woman's crotch.
"Lucy! What has gotten into you!" Kate exclaimed. As the woman got up to move the dog, Lucy turned and presented herself to Kate.
"Looks like she's in heat mom. And guess who she thinks her mate is." Alex joked with his mother.
Kate just frowned at her son. "Very funny mister." Returning her attention to her magazine, Kate tried to ignore her dog.
The two continued in silence for a time. As Alex focused on his phone, he couldn't help but notice Lucy continuing to eye his mother. More oddly, he noticed his mother beginning to bite her lip and subtly sniff as she glanced at Lucy. This behaviour continued for a time before Kate got up and went to the dog. "You're a good girl, aren't you Lucy." Kate exclaimed as she began petting the dog.
Excited by the attention, Lucy presented herself to Kate again. Alex naturally began to turn his attention away from the two, before he noticed his mom had positioned herself behind the dog. Then, as if completely normal to her, Kate began slowly humping at Lucy's backside. Alex watched in amazement as his mother, in her jeans and blouse, got up on Lucy and began thrusting with increased intensity at the dog. "Ok mom. Very funny. Leave her alone." Alex nervously laughed as he watched the lewd display.
Instead of slowing down, however, Kate sped up. Before long, the suburban mother was thrusting madly at her dog's back. Lucy, for her part, was enjoying the ride, tongue hanging out goofily. "Ok that's enough mom." Alex admonished as he went to pull Lucy from his mother.
As he pulled Lucy away, Alex was caught off guard as his mother ground in her heels and began humping with greater intensity. Needy panting could be heard from the woman before Alex finally pulled Lucy away. "Mom! What has gotten into you!" Alex's question was met with a snarl and growl from his mother. The woman barred her teeth and looked as though she were ready to lunge. Alex backed up, worried about what his mom might do.
The anger eventually faded from Kate's face as the gravity of what she had done settled in. "Oh my god! What was I doing!" the woman asked in shock. "I'm so sorry honey!" Kate closed the distance with her son and embraced him in a hug.
As the two embraced, Alex was caught off guard by a small bump in his mother's groin area. Sneaking an eye towards the crotch of his mom's jeans, Alex was met with a shocking sight. A small, pointed nub could be seen protruding from behind the zipper of Kate's jeans. Of greater concern to Alex, however, was the clear liquid coating the surrounding pant area. His mom not only appeared to have a penis, but had apparently ejaculated with it too.
Alex slowly moved his hand towards the appendage, not believing that it could be real. It was real sure enough, and sensitive. As Alex's hands rubbed the crotch of his mom's jeans, his mother straightened as if shocked. A quiet grunt was all the warning Alex got before Kate expelled a small squirt of cum from her new member. As if that weren't bad enough, Kate obviously wasn't done yet. The previously small nub grew in size, protruding further into its denim prison.
"Mom! Look at yourself! You've got a penis! Oh my god! We need to call the hospital!"
Kate gasped as she detected the source of her pleasure and nodded in agreement. As she moved to grab the phone, however, an intoxicating scent caught her mid-step. In a daze, Kate left the room and went down the hall. Alex followed his mother trying to snap her out of her trance. It quickly became clear what was drawing her attention. At the end of the hall stood Lucy. Kate and Lucy's eyes only met quickly before all hell broke loose.
A low groan escaped Kate as she fell to her hands and knees. The woman tried to fight the new urges that were rushing through her body, overwhelming her voice of reason. Alex got between Kate and Lucy, hoping to deter his mother from acting on her new impulses. Instead, he was given a look at the first of the woman's many changes to come. A calm slowly came over the woman. Kate rose onto her knees, giving Alex a clear view of the pulsating member occupying her pants. She calmly directed her attention to the straining zipper at the front of her jeans. Carefully removing the barrier blocking her new appendage, Kate lowered the zipper on her jeans. She then looked her son in the eye, mouthing a silent "I'm sorry".
With that, a red rocket surged through the new opening in Kate's jeans, proudly presenting itself to the world. Kate, for her part, held herself back for a few seconds before bowing to her new hormones. Alex scrambled out of his mother's way as she hurtled herself at Lucy. Alex was only able to watch in horror as his fully clothed mother yipped and growled as she frantically pounded away at her pet. Eventually the woman rose with a howl and exploded into Lucy.
The two remained locked for some time, Kate's knot not allowing her the ability to free herself from her companion. Alex did his best to free his mother, the woman's constant apologies echoing as he tried to help her. Constant pulling to free the stuck-in knot only served to emit a grunt from Kate as she experienced a second shocking orgasm. The two quickly realized their best option was simply to wait. Some time passed before Alex was alerted by a loud plop. Returning to his mom, he found Kate lying on her back. The front of her pants was coated with her seed, but at least the new member had retreated into the confines of her jeans.
As Alex helped his mother up, he remembered the goats. Where was his sister and what was happening to his family?
