She can't do anything on her own.

Jade was having success in preventing her mother from fucking anyone, pulling her away whenever she showed any signs of being horny in public. This worked for a month and a half, but being alone against it the plan was doomed to fail.

On the day in question, after arriving at her house from school, her mother was not there. Jade thought that she could have gone to the supermarket to do some shopping, so she went there to look for her, but was informed that her mother had been there, but had left a long time ago.

With no more ideas, she went back home to look for some clue that would help, but only found that the things bought at the market were at home and stored in the pantry and in the fridge. She tried calling her mother's cell phone, but she wasn't answering.

It was almost 9 pm when she finally answered the call and told Jade that she had met a friend who invited her to go to the show of a famous band that would be held at the stadium in the city, as she had a ticket left over. Jade got worried and searched about the specific show on social media and found that all 150,000 tickets had been sold and that the place must have been completely packed with people.

Going as fast as she could, counting on public transport time, it took Jade 50 minutes to reach the stadium, but it was too late. It was already possible to find futas fucking other people, who had probably just been converted.

Jade made it through the crowd and into the stadium easily even without tickets as the security guards had been converted and were busy fucking. She looked for her mother, but the place was too big and there were too many people for her to walk fast.

The search continued for hours, with the proportion of converted people more and more outnumbering the unconverted, until not a single normal person was left amidst the huge orgy that was going on there.

Jade only gave up looking for her mother when the show was over and the people were leaving, having practically emptied the stadium, and not seeing her mother anywhere, she deduced that she must have already gone home.

Jade had lost track of how long she'd been out, and when she got home, it was already dawn. Upon entering the house, she found her mother in the kitchen preparing breakfast, which made her remember that she had not even had dinner the night before. Yet what she feared might happen had actually happened and she had changed again, and the change this time was much more stark.

Jade's mother cooked naked, wearing only her apron, but she was now eight and a half feet tall, and it wasn't the biggest change. She had her back to her daughter who was staring at her two asses in amazement.

Jade looked down from her mother's wider hips only to see that she had three legs now, and she also had an extra pair of arms below her original one, which she used for cooking.

"You arrived Jade, I was already wondering where you would have gone when I didn't find you at home, but I knew you would be back soon. Sit down, you must be hungry, you'll have something to eat soon." her mother said, turning to Jade when she saw that she had arrived, the apron she was wearing being useless to cover the two dicks and two ballsacks she had in each of her crotches

"Have you changed again mom?" Jade asked

"Yeah, I was having fun with the people on the show and I ended up evolving again." her mother said

"Evolved? Pay attention mom, you're becoming more and more of a freak." Jade said

"You talk like these transformations are bad, but I've never felt better. I feel like my body has been perfected, this can only be an evolution. I don't even feel the need to sleep anymore and any injury heals quickly, what could be better than that?" her mother said

Jade didn't know what to answer. She still didn't know why all this had started and what her mother was becoming. She just thought it sounded silly at the time, but it reminded her of an anime she saw where demonic creatures evolved by killing people, and her mother evolved the more she fucked people.

Judging by the amount of times she had changed, Jade dubbed her mother's current form of Futanari LV3, while her own was that of a Futanari LV2, the other people who had only been converted were all LV1.
