Once the Smiths arrive in school, Jennifer breaks away from her parents, who head to her homeroom. She meanwhiles heads to her locker and friends. She sees Lila, Veronica and Hailey waiting for her at her locker. Jenny decides to take her time getting ready for school while asking to see if her friends notice her large horse cock. Jennifer quickly realizes that according to her friends she always had Kyle as her massive horse cock, which in turn for whatever reason has them fantasying about merging with her father so that she could ram their merged pussy with Kyle. Jennifer only hated Kyle more knowing that if she cums on her father, her friends will be getting what they want.
Jennifer figures this must be how her rival Helena, Sarah and Clara must be feeling. Now that she thinks more into it, it must mean that the reason why they are her rivals is because they want to be fucked by her, but are too afraid to be called lesbians, she thinks.
Jennifer and her friends head to homeroom to start the day. Homeroom happens exactly like normal. It isn't in till it's the first class that things go back to being weird for Jennifer.
Jennifer watched as her father began to talk, while her mother began to strip down herself to her lacy black underwear. Jennifer felt Kyle harden and her pussy get wet. Her ears perked up when her father asked her to act as a example for the cow-girl position. Jennifer didn't need to undress, but she moved her panties away from her pussy to allow her father's dick easy access to it.
Jennifer's father was lying on his back on top of the teachers desk, which was changed to accommodate people having sex on it. Actually now that Jennifer really paid attention to the class it was clear that the class was changed to allow students to have an easy orgy in it. all the desks and floor being comfortable to lie down on or take on any positions.
Jenny hopped on to her father exposes cock and began riding is cock in front of the class. She used her hand to keep Kyle down on her father's chest. Jennifer heard her mother begin to teach the rest of the class about the cow-girl position. Jennifer felt Kyle begin leaking cum onto her father, which began to change him and activate the part of the curse regarding his merger with her friends and rivals.
Jennifer looked toward the class on her left side and saw Lila, Veronica, Hailey, Helena, Sarah and Clara flying from their seats toward her and her father. Jennifer was knocked off her father as the girls collided with them. Jennifer saw Clara and Lila heads attach and merge with her father's chest. Sarah merged with his cock while Hailey merged with his ass. Veronica began merging with Gabriel's left side, while Helena merged with his right.
Jennifer watched as the 6 girls merge with her father turning him into a her, a very sexy her. Jennifer realized her father was now fully a woman, a 6'5" bimbo looking woman. Gabriel now had H-cup tits, a nice plumb pussy and heart shape ass. Jennifer felt a wave of lust run over her and she lost all reasoning, she loved her father she needed to fuck her father, she needed to pump her cum into her.
Jennifer got up and lined her dick with her father's new pussy and with no ceremony or warning she thrusted into the newly minted woman. As Jennifer fucked her father in front of the class, Gabriel began to change more.
Gabriel grew an few extra set of breasts, each going down in size from the recently added H-cup. She now had a H-cups, G-cups, F-cups and E-cups. Jennifer loved the 8 breasts of her father and began playing with the E-cups since they were the closest to her. Gabriel felt her hips widen and her thighs thicken. She now had a permanent thigh gap despite her nice juicy thighs and fat pussy. Her pussy had grown eating up more of Kyle.
Gabriel's hair changed color to green with blonde highlights. Her hair lengthen down to her heart shaped ass. A thin tail grew out of her ass, covered in green scales. Large draconic wings burst out of her shoulder blades. Her belly toned down becoming muscular. Her pussy grew muscles in it, allowing her to squeeze down on Kyle. Her pussy also grew a long prehensile tongue. Her pussy despite being under her control was also under the control of Sarah. Her asshole became a muscular pussy which was under the control of Hailey.
Gabriel felt her feet change as she wrapped her long legs around Jennifer's waist. Her feet changed into clawed high heels. 4 snakes came out of her head. They were under the control of the other girls. The girls moaned loving the feeling of finally being one with Gabriel and getting railed by Jennifer's Kyle. The girls wrapped their long bodies around Gabriel's tits and attached their mouth pussies to their nipples. Gabriel's tits began leaking milk. Gabriel felt the girls sucking their on milk up.
Along Gabriel's legs, arms, and shoulders spikes grew out. A massive set of horns grew out of Gabriel's head. Gabriel grew 5 more pair of arms, giving her 12 in total. She then felt as Jennifer rammed Kyle all the way into her womb as she, Jennifer and Kyle reached their climax. As the mutating cum filled her womb, her body was covered in vines, leaves and flowers.
Jennifer loved her father despite all his changes, actually she realize she loved her father being a woman more then a man. Jennifer felt that her mother would have been better as a father while her father would have been better as her mother.
Jennifer woke up, looking to her left realizing that the whole class saw her fuck and fill her former father with tons of mutagenic cum.
She felt she could die and the worst of it all her mother as still giving the class a lesson.
