Madison watched as the giant girl sat down on the field and picked Christy up, positioning the cheerleader right in front of her enormous pussy. Then the 70 foot tall giant used Christy like a dildo, spearing Christy’s 15 foot cock into her pussy and pumping without pulling all the way out. It would have been a normal masturbation scene like any other explicit video, but this was a literal giant masturbating with a living person like they where a sex toy.
Madison could only stare in wonder and horror at the majestic sight. It was like when ancient people spoke about witnessing literal immortal beings doing miraculous things when the world wasn’t ruled by man. The big boobed centaur felt her own cock start to peak out of its sheath as she continued to stare at the giant pussy leaking a waterfall of vagina juice as the giant orgasmed. The lips of the meat cave moved like a monstrous maw squeezing the giant cock belonging to Christy. Then volcanic heat and mass spewed out of the fleshy cave as Christy jizzed in response to the giant’s climax. The torrent of viscous clear and white liquids spilled onto the green grass field like a sexual mudslide.
Madison was horny, and her stallion dick was fully erect now. She had just witnessed an otherworldly sexual intercourse. Magic was real, and it was sexy. The centaur couldn’t wait and stare any longer, she needed to find out about what happened, so she galloped towards Christy with her throbbing erection.
Christy restored her genitals back to normal and turned Olivia back to normal human size with some shots of the magical transformation gun. Christy then started to walk away leaving Olivia layinnging in a steaming streaming lake of sex goo. Before she could leave the school, Madison stopped Christy by almost crashing into the shorter girl in her mad rush to meet the blonde cheerleader.
“Woah, why are you in such a hurry Maison?” Christy asked as she regained her footing.
The centaur placed her hands on her wide hips, “I saw you getting used by a giant like a dildo, and you had a giant cock! That’s weird like out of this world magic weird! You’ve got some explaining to do Christy.” Madison wasn’t going to let Christy leave without answers.
Christy inwardly scolded herself, did she really forget to turn on the reality change when she had her giant fun. “Madison it’s a long story, but I have to go so I’ll explain it next time,” Christy Aimee the magic gun at the centaur and fired before Madison could react.
“What-Christy!” Madison felt her horse cock grow hot like melting iron making her stumble in fright. Christy took advantage of this distraction and ran away. "Christy! Wait, Christy!” Madison yelled as the burning heat dissipated. Christy was gone.
Madison started to walk and look for Christy again, but something felt wrong. Her dick, her proud long equine cock! She couldn’t feel it’s familiar weight or the hanging mass of her family jewels. She felt something similar, but terribly different in between her back legs. Madison couldn’t see her genitalia without a mirror but she somehow knew what had happened. Christy had transformed Madison’s life long partner of a cock and balls into a pussy! Later on after Madison went back to her home crying at the lost of her fuck rocket, her pride, her long dong, she would find out that her new pussy was not a horse pussy but a small human vagina.
