A light-bulb popped inside Ty's head and he finally knew what to do, making his wicked smile grow wider on his face. Wouldn't it be so funny and erotic for the janitor to turn into a beast and then rape Mary? It was a very amusing thought, and Ty didn't hesitate for another second and internally wish for the man to turn into a random beast.
"O-ohh what is h-happening..m-my body!" The janitor groans out and begins his transformation, his muscles gaining more mass as his face starts to distort and shift into that of a Rhinoceroses. Mary stopped licking to notice his sudden changing, screaming at the top of her lungs in sheer fright. The older male's clothes started ripping from his gaining muscles, the thick smell of rhino musk started to fill the closest as his whole body was nearly complete in it's transformation. A tail sprouted above his rear, and his cock gain girth as it grows to a solid 15 inches fully erect. Mary screamed again and crawled to the door, making Ty shift over to get out of the way for her attempt escape. She furiously turns the doorknob, panicking after realizing it was locked. The now rhino janitor roars out when the transformation is complete, being a seven foot anthro rhino who was really, really horny.
"S-so...HOrny!! Come here!" The rhino grabs Mary's arms with his meaty hands, pulling her into his grasp and forces his thick tongue into her mouth. The teenage girl had tears running down her face as the big beast's tongue enters her mouth, making her gag as it almost slides past her throat. Ty watches with amazement of his work, stroking his average size cock like there was no tomorrow. The rhino kept the forceful kiss going for another couple of seconds, then pops his tongue out of his mouth and goes on to the next best thing.
"P-please d-don't!" Mary tried to plea as he sits down again and lifts her up onto his lap, the tip of his throbbing shaft touching her wet folds. The crying slowly started to turn into a faint moan, as the beast's musk was overtaking her senses. "I-it'll hurt.." The janitor snorted and impaled her halfway down his cock, stretching teen's vagina and taking her virginity. Mary screamed again, but no noise came out as the pain was too intense to even produce a sound. The beast groans and starts using the teen girl as a fleshlight, lifting her up and down on his shaft as blood, juices, and pre-cum lubricated them. Ty took a huge intake of air and exhales with a moan, the musk was the only scent in the closet and he couldn't be any happier. Now that the janitor was a beast, Ty decided it was safe to reveal himself and not be invisible anymore.
"Wow Mary, look at you..taking such a huge cock like a whore.." Ty lays down with his head near the rhino's crotch, the sight, smells, and sounds of the fucking was a fantasy come true. "Don't mind me, big guy. Just helping myself." Ty sticks his tongue out and begins to lick the huge testicles on the beast, the salty flavor of them was so delicious he had to wish for his urges to stay in control. The janitor roars from the boy licking and sucking his ballsack, pulling and impaling Mary harder and faster on his cock while enjoying the extra person pleasuring him.
"Fuck mefuckmefuckmeeeee!!!" Mary finally gave in to the lust, grabbing the Rhinoceroses horn with both hands for support. "Fuck me uppp!!! YESS IT HURTS SO GOOOOODD!!!" The moment felt like it went on for an hour, but it was actually just minutes of very intense sex-making.
"Take it you sluuuttt!!" The janitor rhino roars and kept Mary halfway on his cock, climaxing hard as his seed starts to slowly inflate her womb. Ty giggles and laps up all the cum, blood and juices that spurted and poured out, getting up to stand on his own two feet and jacks off again. As Mary cries out in pain and pleasure, Ty cums on his own and shoots a few ropes of sperm all over the teenage girl's back. The muscle-bound animal gently lifts the girl off his cock, watching the cum flood out like a waterfall. He immediately cuddles her into his arms, the now-whore girl smiling and licking the rhino's nipple playfully and lustfully. "Mmmm you're mine now, little slut..All mine.."
The whole closet felt so hot, the three's sweaty bodies made the air sort of hard to breathe, but kept their arousal up and their cocks hard. Ty ponders what he should do next, a few ideas did came to mine..
