Rick looked in disbelief at his transforming family. He backed toward the patio door. "I'm calling 911, we're going to get some help here. Mom, Aunt Karen, just hold on, try not to make it any worse, okay?"
His mom's widening nostrils flared. "Right. Call an ambulance, sweetie. I can get this thing under control. I just need to--HAWW!" She brayed as her ears grew long and fuzzy and her face grew forward, beginning to resemble an equine snout. "Need to focus."
As Rick ran inside, Karen called his sister Kate over. "Sweetie, don't be afraid okay? We're going to get to a hospital and find out what's happening to us."
"Aunt Karen, you and mom and Uncle Will, you're turning into animal...things!"
"Shh, honey, it's--"
"You have a tail! And a...a penis!"
Karen shivered as her tail twitched. "I know, honey, you don't have to remind me! Thinking about it is making me feel…oh lord…" her cock began to swell. She bit her lip and clenched her hands, the pain of her new claws digging into her palms distracting her from her lust. She took a deep breath and exhaled. "Can you take Savannah and look for your uncle Will? He needs help, too. I don't know where he ran off to."
Kate nodded. "Right. Come on, Savy, we need to find your dad." The two dashed off and out the gate into the neighborhood to look for Will.
Rick's other cousin Samantha grabbed the garden hose and turned the spigot on, pointing the nozzle at her changing family. "Okay, I'm going to keep an eye on you three. If it starts getting out of hand, I'm gonna...Uncle Jack?"
Rick's father shuddered and bent over the table, rubbing his thighs together. Jennifer, Karen, and Samantha watched as his ass began growing, rapidly swelling with mass and stretching the seat of his pants as it grew from nothing at all into a feminine bubble butt. A growing mass pressed between his ass and his pants strained for freedom, thrashing as it grew longer and longer. "Tight...so tight. Gonna...HAWW!" He fumbled with his pants button, trying to undo his pants as they grew tighter and tighter, then just as he got them undone and brayed and started to pull them down he shuddered as a ropy donkey tail pulled free and another wet squirt issued from his groin. He lay against the table, his legs quivering, a look of ecstasy on his face as the aftershocks of an orgasm rippled through him.
Jennifer and Karen grew erect again at the sight of his display, but before they could react further Samantha hit them with the hose. "Oh no, you don't! I'm not gonna let you lose it if I can help it." Their clothes clung wetly to their skin, but at least the icy water had killed their erections. She turned the hose on Rick's father as well. "You too, Uncle Jack. Whatever is happening to you, we're going to hold out for an ambulance."
She considered whether it would be better to keep the three separated or to have them all grouped together. If they were separate it might be tough to keep them all under control with one hose; but if they were all clustered together that would increase the chances that bodily contact would cause them to lose control and it could make it much worse for all three. She couldn't let that happen. All three of them together, her mother and her aunt, turning into a rat and a donkey, embracing and making out and grinding their animalistic dicks together, and her uncle in the midst of it. She closed her eyes and bit her lip. Her thighs rubbed together involuntarily. She had seen the way he had been looking at Jennifer's dick. Would he suck his wife off? Would he offer his now girly ass up? Or did he have a pussy now to match Jennifer's donkey cock? She could swear she could smell it. She bit her lip and felt a tightness in her pants, a straining for something. She reached down and felt a stiff rod in her jeans.
"Oh god, I'm...ohhhhh!" She moaned as she felt something pent up inside of her release. The shaft in her jeans jerked and a stream of jizz spurted from her new cock, seeping through the denim. She groaned as she felt herself bearing down sharply and one, then a second testicle dropped heavily from her groin into a new ballsack. She looked up at her mother, whose rat cock had jumped back to attention. "Mom? Mom, I need...nnghhh…" She groaned again as her balls churned and clenched and another spurt of cum sprayed from her new dick. Her eyes rolled back and she grabbed at her shaft, torn between trying to stop it and trying to milk every last drop.
