Having come like never before Jess put on her clothes again. Helen used Chronivac just to reduce the size of her cocks, keeping them both a foot long each, she kept them safe up inside her blouse, but her balls were in plain sight beneath her miniskirt. Margaret refused when her friend offered to return her to normal, but asked for reality to be changed so that no one else would know about her change.
As they exited the bathroom they ran into two mall security guards who had been called by the woman who had seen them having sex in the bathroom earlier. The security guards tried to hold them until the police arrived and took them away for indecent exposure, but the trio ran away with the two in pursuit. During the chase, security asked for reinforcements and soon the trio found themselves cornered.
Margaret borrowed Helen's cell phone saying she had an idea and so she used Chronivac on herself. soon the lower part of her taur body grew into a horse body, making her a full centauress. "Now hop on my back so we'll have some advantage." she said handing the phone back to her friend.
Jess and Helen mounted the centauress, who asked them to hold on tight and started to run as fast as she could. Margaret couldn't run that fast due to the amount of people who were present in the place, which became more complicated thanks to the onlookers who stopped to see the escape. When they were finally getting close to the exit, Margaret had to stop to avoid running over an elderly man in a wheelchair who couldn't get out of her way in time, so a woman from the security team managed to approach from behind and grab her tail.
Margaret could easily escape with a kick, but she didn't want to hurt anyone and knew that doing so could end up knocking the pair mounted on her. Helen acted quickly and used the Chroni app on the security guard, making a cow's large udder full of milk grow in her belly. The astonishment caused by her own transformation, she loosened her hands and thus allowed the centaur to escape. Even after they left the mall, Margaret kept running until they reached the square three blocks away.
Helen laughed and said "That was fun, we might try something like this again someday."
"It's true, I got so excited that I got horny and now I'm hard." Margaret said as the pair got off her back. Jess and Helen saw that underneath the centauress' horse body were two hard cocks, each at least 2 feet long. "I remembered how much you seemed to like yours and added myself in my last change."
"You really are a pervert. Although I am too and I know exactly what is needed now." Helen said and changed herself once more with the Chroni app, she grew a second pair of arms and a second head, along with a third breast to fill the open space when her torso widened a bit. She then bent down and got under her friend's horse body, where with her upper hands she held Margaret's cocks and started sucking both, meanwhile she stroked her own cocks with her lower hands.
"Oh Helen, this feels so good. That's right, keep it up." Margaret said as her friend, who had also adjusted her body to account for the size of her limbs, stuck both cocks in until she was face to face with her four testicles ballsack.
As Margaret reveled in the double blowjob she received, she swung her tail back and forth and with that Jess saw that she had a pussy too.
The girl approached and began to play with the female entrance of the centaur, who had almost forgotten her presence and was taken by surprise, but one that she adored immensely.
Helen realized what had happened and stopped the blowjob a little, taking her cell phone and using the app on her daughter, in which a shealth quickly formed between her legs and from there came a 2-foot hard horse cock. "If you want it then you need the right tool." she said to her daughter and went back to sucking her friend's dicks.
Jess took off her pants and saw that despite the horse's dick she didn't have balls, but she didn't care about it, she just climbed on a bench and asked Margaret to reposition herself, thus being able to penetrate her.
They continued the threesome until Margaret came, Helen held back, swallowing the whole centauress's cum as she continued to jerk off, which led to her own orgasm. Jess didn't take long to reach her own orgasm either, digging her cock as deep as she could and stopping there as she came.
After another orgasm Jess and Helen (who had a slightly swollen belly due to the amount of cum in her stomach) sat on the park bench while Margaret laid her horse body on the ground to recover from the orgasm.
Once recovered the adult women looked at each other and without saying a word they understood what they intended. Margaret then got up and Helen got on her back.
"Jess, I'm going to spend some more time with Margaret. If you want you can go home before me." Helen said
