"I'm more than in." Jen said to her father/mother
"Come on Jen, keep making me feel this way. I've never felt so good." her shemale giant anthro unicorn centaur mother said
Jen climbed behind her mother's ballsack, climbing her ass until she came face to face with a large entrance that was her mother's equine anus.
"Yes Jen, this is what I needed. Go as deep as you can." Helen said when she felt her dauther entering her ass
Jen obeyed her mother and went deep in her ass, even when she was all the way in, and kept groping in the dark until she found Helen's prostate. When she reached that Jen felt a sudden movement and heard a sound too muffled to understand what it was, and then by the rocking her mother was making big movements. She knew she was giving her mother pleasure, but she thought it wasn't enough, because there was still too much room for her in there, she wanted to get inside Helen much more. As if given her wish, Jen felt her body change. All her arms and breasts were sucked into her body, which became completely rigid and she couldn't move anymore, but the place was getting tighter, which to her meant she was growing. Eventually a part of her body came out of her mom's asshole, which was the part of her body that wasn't quite rigid, but hung big and heavy. She didn't know it, but she had grown into a giant disembodied cock and had a ballsack almost as big as Helen's hanging outside. Even knowing that she was completely stuffing her mother's ass, Jen wasn't feeling satisfied. She knew that just standing there and not being able to move would not be the best thing to do, and she wanted to do something for her wyvern father/mother as well. This feeling triggered a new change in Jen. At the base of the giant cock she was, just behind her balls, grew a shapeless mass of flesh, which then became an almost exact copy of her original body, only now she was as tall as her mother and had a cock. on her crotch, with which he fucked her. Jen herself also had no legs, but a long lamia-like tail, which grew longer and longer.
When she could see again, Jen realized that Alex had changed more. She now had four heads and each had three pairs of eyes, as well as four pairs of enormous wings.
As for Helen, who received pheromones directly inside her body, the change was absurd. She now had three pairs of arms, as well as three pairs of massive breasts. Her equine bottom had grown much longer and in the space between the front and rear pair of legs, she had grown two more pairs of legs, each with its own set of dick and balls between them. As long as the dicks, each of them passed under the ballsack in the front assembly and its tip almost touched the base of the dick in front of them, except for the most front one which the tip rose majestically from between the frontal pair of legs.
Jen wondered how she was going to do it, so at this point her long tail split at the end and went in five more directions, in which five more exact copies of the top half of her body were formed. It was a strange feeling for Jen having six interconnected bodies, having control over all of them and seeing six different points of view at the same time. Jen's total size was now bigger than her parents combined.
Of the six bodies, three had a dick in the crotch that rivaled Helen's (with one already fucking her mother's ass) and the other three had pussy. She then guided the three bodies with pussies to each pull one of her mother's cocks to the side and allow themselves to be penetrated by her, the two shemale bodies walked towards Alex, who was kissing Helen with one of her heads and with another two sucked the nipples of her upper breasts. With one of her shemale bodies Jen fucked her wyvern mother's pussy, while with the last one she shoved her cock into the free head's mouth.
The trio of giant monsters having sex managed to break the limits of the curse's magic. As much as it was specified that people would treat it like it was no big deal, with their size, the very loud moans, and some damage they did in the neighborhood, the neighbors couldn't just ignore them. Even after the three giant monsters came, they weren't satisfied and continued to have sex non-stop, without worrying about anything else.
