As Lucy was making her way home from her walk, Jen felt a now familiar sensation as another pill slipped out of her mouth and was caught on one of Lucy's swinging hands. Upon feeling the pill land in her hand the dog girl looked down at it curiously, sniffing at it for a moment before she licked it out of her hand. Her breasts grew larger becoming a size that would be compared to basketballs if they were one a normal sized person, but on Lucy's body were the size of minivans. Three more sets of nipples then appeared down her torso, before quickly ballooning out into six more breasts, each row slightly smaller than the one above it.
After Lucy finished changing the dog-herm continued on her way home, her eight breasts bouncing around with each step. About half an hour later the three girls had arrived back at Jen's house. The first thing Lucy did upon returning was mount her sex doll, releasing the pent up lust from her earlier transformation. After she had shoot a couple of loads into the doll Lucy flopped down on the floor and began playing with one of the chew toys on the floor. Eventually the door from the house opened and Jen's mom walked in, back from work, already wearing a loose t-shirt and sweatpants, and carrying a bowl of popcorn in one hand. She stepped into the elevator and rode it up to the upper railing.
“Lucy! Over here girl!” Upon being called, Lucy got up and walked over to stand in front of Jen's mom. The dog-herm moved her head over near the railing, allowing Jen's mom to pet her face and scratch her behind the ears.
“Good doggy, did you have fun on your walk today? Okay Lucy, stay right there while I go talk to the girls” Jen's mom moved over to the elevator and rode it down to the lower railing and stepped in front of the two cock-girls
“And what about you two? Did you have fun walking Lucy?”
“I guess you could say that, we ran into Martha while we were out.” After Jen's reply she felt a pill slide out of her mouth and watched it fall into her mothers bowl of popcorn.
“Oh that's nice, I hope she's doing well. What about you Claire, how was your day?” After asking her question Jen's mom grabbed a handful of popcorn and tossed it into her mouth.
“Well, I saw a mermaid over by the river. That was really cool!” As Claire talked Jen's mom's hips began to widen, her legs thickening and growing longer.
“That must be Jessie! She's married to one of my coworkers, lovely lady.” As Jen's mom continued to converse with the girls her hips and legs continued to grow, quickly becoming out of proportion with with her unchanged upper body. Her quickly widening hips caused her once loose sweatpants to cling to her body, revealing a growing bulge between her legs. Eventually her pants reached their limit and ripped apart, the shredded pieces fading from reality before they hit the floor. With her pants out of the way their was now a clear view of the rapidly growing horsecock between her legs. Now freed from their trappings her leg's growth accelerated and white fur began to spread out from her crotch, quickly covering her hips and legs. Once the fur reached her feet her toe nail expanded and darkened, transforming her feet into a pair of cloven hooves. Finally, a horse tail grew out from above her butt as the her growth stopped. Jen's mother now stood over twenty feet tall, but most of that height was concentrated in her horse legs, her upper body looking tiny in comparison. Her hips now were now so wide that her arms wouldn't even reach halfway to either side. The most striking thing of all though was her gigantic horsecock, it's fifteen foot length now eclipsing either of the two living cocks between the Lucy's legs. Accompanying her cock was a pair of balls so large that even at her height, they still dragged on the ground behind her.
Jen's mother was, like all the other victims of the pills, incredibly horny from her transformation her cock stiffly extending from her crotch between Jen and Claire.
“Why do I feel so horny all of a sudden? Lucy, would you be a good girl let me fuck your tits?” Upon hearing the request Lucy excitedly stepped closer to the railing and pressed her owner's slab of horse-meat between her eight breasts. As Jen's mother trusted her hips into the chasm of Lucy's breasts, she reach over with her proportionately tiny upper body and pulled Jen and Claire over two her.
“Don't think I was about to ignore you two as well” Jen's mother said before pushing both of the cock girls down between her massive thighs, leaving each girl separated by her massive ballsack. Both cock-girls soon gave in into their lust and began licking and sucking on the horse-balls as their shafts where stroked by the equine thighs enclosing them. Jen's mom was the first to cum, hundreds of litres of jizz flying into the air and landing all over Lucy's body, as well as a good amount of the surrounding floor. Soon after the dog-herm came as well, the two cock-girls plastering the wall with their seed as Lucy howls in pleasure. After their orgasms subside, Jen's mom has Lucy lick her clean, the dog-herm greedily swallowing both of their cum. Once she was clean Jen's mom said her goodbye's before taking the elevator back down and walking through the door into the house, both of which had grown significantly larger to accommodate her now much larger frame. After Jen's mother had left Lucy continued to lick up the cum from the floor and walls, until the only liquid left on either was her saliva. As she did this the two girls had a short conversation.
“God, I just had sex with my mom, and the crazy thing is that I don't even feel that grossed out about it” Jen said fearfully
“You didn't seem to have any reservations when you told my mom it was okay to have sex with us.” Claire jabbed back
“Maybe being a cock is having some weird effect on our minds, making us feel fine with whatever as long as we can orgasm?”
"I don't think it's anything like that, both of our mom's seemed to also be fine with it after they were transformed, maybe when the pills change you in sexual ways they lower you inhibitions?”
“That sounds plausible, but does that mean that I'm slowly going to transform everyone around me into crazy sex addicted freaks?”
“I wouldn't worry about it, I mean, it feels amazing and it's not like we can do anything about it anyways right?”
“I guess.....” By the time the two girls had finished their conversation Lucy had finished cleaning up and was about to go lay down when another person came in from the house, this time it was Claire's father.
“Hey girls, I was just about to start on dinner for the rest of the family, so I figured it was about time for Lucy's dinner as well!” he announced as he made his way over to the table. Lucy excitedly bounced over to her seat, but before she sat down Jen felt another pill fall out of her mouth and land on the table. When Claire's father reached the top of the table by climbing the ladder, he began to move over to the level that deposited Lucy's food into her bowl when he noticed the pill sitting on the ground and picked it up.
