She is becoming an anthro

After the conversation he had with his mother, Jack still feared her future, but found himself unable to do anything about it. He then decided to lower all resistance to Kelly's advances towards him. He was grateful that she never even tried to fuck him, but he stroked her dick whenever she asked, and sometimes he fucked her pussy or ass.

Just as Jack feared, his mother's transformation continued with her becoming more equine with each passing day. The first change he noticed after talking to her was the day after that, when her legs had completely changed shape and were now the equivalent of a horse's back legs, only they didn't have fur. Her ass also took on a more robust shape, clearly already equine in form.

Then, with each passing day, Kelly's body became more and more equine, being slowly covered in brown fur. She didn't lose her hair, but her face also lengthened into an equine look. Her entire body was growing proportionally, with the exception of her breasts which were growing faster. A development that occurred, what Jack and his mother believed to be because, apart from her dick, the rest of her body was still entirely female, a second pair of breasts, much smaller than the original, appeared just above the base of the her dick. Due to her growth, Kelly had already given up on wearing clothes, assuming the animals' nature of always being naked.

Despite everything, Kelly insisted on leading her life as normally as possible. She didn't want to hide what was happening to her from anyone, because if she turned completely into a horse, people would miss her disappearance and this could create problems for her son.

After a month of changing, Kelly's transformation seemed to stop. At this point she was already an anthro horse. Her breasts were now each at least twice the size of a person's head, while her lower breasts were the equivalent of an E-cup on a normal woman.

"Hey Mom. Now that you've stopped growing, I think we can get you some new clothes." Jack told the 11 foot tall anthro horse that was his mother when she got up after eating her breakfast on a Sunday.

"I could, but I don't know. I've gotten used to always being naked and I feel comfortable being like this." Kelly said

"Mom, please. You may practically be a horse now, but you still have your humanity. If you want to always be naked at home, do whatever you want, but at least wear something when you go out." Jack said

"Okay, I'll do you it. At least this much I can do for my dear son." Kelly said, lifting Jack into a hug. Becoming part horse greatly increased her physical strength and now she had to be very careful not to hurt him by accident.

As Kelly held Jack, her cock grew hard and left her shealth, rising to the nearly four feet it now possessed.

"I'm very sorry. You don't like it when I have an erection at a time like this, right?" Kelly said

"At least not while we're eating. Now let's go outside so I can take care of this." Jack said

The two went outside to the back of the house, because with her current size and weight, the stairs were not resisting Kelly going up to the top floor of the house. Another reason they did this was because her basketball-sized testicles produced a lot of cum and it would take a lot of work to clean up inside, so they made her cum outside so the rain could wash her cum away.

Kelly sat on the lawn, where she watched Jack undress while waiting for him.

Jack went over to his mother and stroked her dick. He had already assumed that he actually liked this, the expression of happiness on Kelly's face when he stimulated her made him happy too, so much so that he also got hard when he did it.

As she did other times, Kelly, before cumming, asked Jack to stop and turned around, offering her ass and moving her tail out of the way, offering him to fuck her ass or pussy. He chose the pussy.

Due to her size and having an equine pussy, Kelly knew that Jack wouldn't be able to do much for her on his own, so she learned to control her internal muscles so that they both had as much pleasure as possible. She placed her dick between her breasts and stimulated it by rubbing it on the lawn while titfucking herself.

Kelly's orgasm made her create a large puddle of cum, which no longer surprised them. Jack lay on her back for a moment, stroking her brown fur, resigned to what his mother had become. Despite his acceptance, he hoped that her change hhad stopped for good.
