Jack finds that his mother's dick is different

On this day, Jack left for school, saying goodbye to his mother, who was carelessly jerking off in the living room of their house.

The day at school was completely uneventful, but he didn't expect what he found when he returned home.

Arriving, he found his mother in the kitchen preparing dinner, wearing the same extremely revealing outfit as always. Jack looked closely at her and then noticed something that seemed different to him than before. The bulge formed by her balls, which could be seen from behind between her legs, was much larger than before.

Kelly turned to Jack and said "Hi dear, do you need anything?" giving a view of the front of her.

His mother's balls were definitely bigger, but the shape of her dick wasn't there, but a shape he thought he saw somewhere, but he couldn't recognize what it was. Speechless, Jack couldn't stop looking at Kelly's crotch.

"Oh, you already figured that out, right? And I see you liked it as much as I did." Kelly said, shamelessly pulling down her pants to reveal a huge black ballsack, as well as what Jack now recognized as a shealth. His mother now had a horse's cock between her legs, one that probably put the previous one to shame.

"How did this happen?" Jack asked

"It was the same as last time, it just happened out of nowhere. I was at my wits end when I felt my dick being sucked into my body, then I looked scared that I had gone back to my old self and found this. You won't believe how much better this dick is than the one I had before." Kelly said, and her equine dick immediately started to pull out of her shealth as it got hard. This one was actually much bigger than before, being at least 20 inches and with the tip at her eye level. She started furiously jerking off right then and there.

"Mommy, please." Jack said

Kelly stopped stroking her dick and said "I'm sorry, I forgot that I said myself not to cum in the kitchen. And at this time I'm not willing to clean anything. I'll quickly go to the bathroom and be right back." then she went upstairs to the bathroom.

Watching Kelly walk, Jack noticed that in addition to her balls and dick having changed, her ass seemed to be a little bigger too. As she passed him, Jack saw that his mother's vagina and anus had also changed into the equivalent of a horse's.

Kelly's moans masturbating could be heard throughout the house, as she hadn't closed the bathroom door. Jack watched his mother masturbating from the bathroom door, worried about the changes happening to her and wondering when they would stop, as well as what would become of her. Along with that, he found himself a little excited, but he tried to brush it aside. "It's not possible that I got turned on by watching my mother jerk off with a horse's dick." he thought

Jack watched his mother until she lowered her dick toward the toilet and cummed, shooting load after load of equine cum while flushing.

After that, the rest of the day was technically without anything flashy, but Jack found more changes in her sooner than he expected.

The next morning, Jack found his mother in the kitchen again, now preparing breakfast for him to eat before school. Immediately his gaze focused on the ponytail that Kelly now had and was swaying from side to side.

"Good morning. You can wait at the table, breakfast is almost ready." Kelly said

Jack went to the dining room and waited for Kelly. In less than five minutes he heard the sound of footsteps approaching, however the footsteps were very heavy. When he saw Kelly arrive, Jack was surprised again to see that his mother now had hooves instead of feet.

"Mom, this has to stop, we need to get help quickly." Jack said

"Why? What has to stop?" Kelly asked

"Isn't that obvious? Just look behind you and your feet." Jack said

"Yes, I have a tail and hooves now, but that's no problem for me." Kelly said

"Of course it's a problem. Don't you understand? If you continue like this you may end up completely becoming a horse." Jack said

"So what if I become a horse? I'm living the happiest moment of my life with you, that would be a small price to pay." Kelly said

"What do you mean the happiest moment? The situation has never been so worrying. I'm scared, I'm afraid you'll become a simple animal and won't remember me anymore." Jack said, without noticing a single tear running down his face, which his mother noticed.

"Oh dear, I'm sorry if I caused you such worry. It turns out that before you treated me as if you wanted to keep your distance, I even thought you might hate me, but the way you started paying me more attention and getting closer after my dick grew made me feel loved. That's why I gained more confidence and started acting in a way that was attractive to you." Kelly said

Jack was astonished to know that all of his mother's actions were on purpose to get his attention.

"I, I'm really sorry if I made you feel this bad before, but we have to act before it's too late." Jack said

"Do not worry dear. I did a lot of research while I was alone and I didn't find anything that explains what has been happening to me. But fear not, I promise that even if I completely transform into a horse, I will still remember you and love you as always." Kelly said, hugging Jack tightly.
