Silence descended on the group as everyone turned their attention to the paramedics. Eventually one of the paramedics moved forward to take charge. "So, uh, what seems to be the problem everyone? Other than the obvious." the man asked embarrassed.
The silence returned for a time before it was interrupted by a distinct plop as Jennifer removed her penis from her husband. Everyone turned towards Jennifer, who now hid her equine face. Muffled cries of "what have I done" could be heard coming from the woman. Samantha for her part had also turned a bright red as she looked down at her new red rocket in shame.
"It's about time you showed up!" a disheveled looking Rick cried as he ran from the house. "Please, you need to help my family! Something's happening to us! Wait, Mom! Samantha! What happened to you?" Rick's hope at seeing the paramedics faded as he saw the changes to his family.
If possible, Samantha and Jennifer grew redder with embarrassment, Jennifer's cock quickly going limp as her arousal plummeted.
"Look, kid, can you explain what's going on here? This is crazy. Your mom looks like a donkey, that girl has a dog penis, and she looks like she's crazy" the paramedic asked gesturing towards Jennifer, Samantha and Karen.
"I don't know. I was just enjoying my birthday party when..." a figure dropping down behind the paramedics distracted Rick's attention. "What is that? Look out!"
The paramedics turned too late. The creature grabbed one of the men by the throat and pulled him in for a kiss. Rick gasped as his Aunt Karen threw herself at the female paramedic. The woman's eyes went wide with surprise as her mouth was filled with Karen's now long tongue and her breasts were groped by long, sharp claws.
Looking back at the rest of his family, Rick saw the sight begin to take hold of them as well. All three family members had only just composed themselves, with Samantha having tucked her new penis into her pants, Jennifer buttoning her jeans up around her cock, and Jack having pulled his pants back on. Rick watched as a sharp tent stuck out from his cousin's crotch, his mother's penis rose upward as it began growing erect, and his father began rubbing his crotch excitedly. Looking for a way to break the spell, Rick lunged at the hose Samantha had wielded earlier and let it loose on his family.
Cocks shrunk and looks of lust turned to surprise as his family was soaked in water, or most of his family that is. As the water hit the trio, Jack began running towards his new rat family members. Unfazed by the spray, Rick's father continued running until he collided with one of the remaining paramedics. Both went down in a heap as Jack smothered the man.
"We need to get out of here now! Are you three with me? Or are you staying here?" the remaining paramedic demanded.
"We're going. Mom, Samantha, come on!" Rick pulled his mom and cousin in pursuit of the paramedic. As he listened, he could hear additional sirens in the distance. He took a quick look back as they fled from the yard.
Rick's father, aunt and uncle at this point, were fully animalistic in appearance. The three had gathered amongst themselves, crying in ecstasy as they stoked themselves to orgasm. Karen moaned in desperation as she thrust her fully erect rat cock into her husband's eager mouth. As Karen exploded in orgasm, an answering bray came from Jack as he rubbed himself against her backside. Before long, cum sprayed from the trio as all three brought themselves to orgasm.
This left the paramedics off to the side. The first man to be jumped was frantically fondling a large bulge in his pants, occasionally letting out grunts as squirts of liquid sprayed from the appendage. The woman was staring down in shock at a massive tent that had formed in her own pants. Mumbles of "Oh my god. Oh my god." could be heard before the women gasped, eyes going wide, and ejaculated over her remaining coworker. The remaining paramedic, in turn, let loose his own spray of cum before throwing himself at his colleague. The woman's look of surprise was only temporary before in a series of spasms, her cock burst through its confines and presented itself. Not needing an invitation, the woman's co-workers began licking at the new appendage, prompting additional grunts, moans, and ejaculations.
Rick's eyes left the orgy as he ran from the yard.
"So does anyone want to tell me what's going on!" the remaining paramedic demanded.
"Yes, please tell" a police officer asked from behind the paramedic. "We've gotten recent crazy reports of animal sightings and public indecency in this area. Someone want to explain the source of all these complaints?"
"I don't know what happened! I was just taking birthday pictures of my son when all of a sudden I felt strange. I..."
"Mom!"
Rick's mom was cut off as his sister ran across the lawn, followed by his cousin. Sally, his next door neighbour, chased after them.
Rick, Samantha and Jennifer found themselves stunned into silence as they were hit with a barrage of questions from the newcomers.
