Johnny Sex

The Twins

Johnny had drank hundreds of experimental concoctions his sister's brewed up in their lab, each with their own reactions.
But he had never had one that made him so horny.
As the sharp liquid danced down his gullet, he felt heat radiate through his body, and down to his pants.
His veins bulged on his arm as the lump in his pants grew three sizes bigger, he was no longer Johnny Test, he was Johnny Sex.
Johnny Sex grew several feet in front of his twin sister's, his clothes ripped down to the floor. They tried to look away but couldn't, they had never felt a man's touch. Obsessing over Gil, their next door neighbor, they were too distracted to notice what a man looked like.
Johnny Sex grabbed his petite sister's by one in each hand and threw them onto their bedroom bed, big enough for the three of them.
Jizz dripped from Johnny's 15 inch cock as he rocked the floor each step he took.
"J-Johnny! Please!" Susan and Mary pleaded, as they knew their virgin holes couldn't handle the mutated cock Johnny nearly dragged on the floor.
Johnny just grunted and took Susan in his hands first. "You. First!" Johnny Sex yelled.
He tore off her clothes and pinched her throat closed while his now 8 inch finger pushed deep into her scientist pussy.
Mary watched in horror as Susan was finger fucked until her legs gave out and she dripped down to her thigh high socks.
Johnny's cock was now hard, and 20 inches long. Sadly for Susan, he was still a grower and not a shower.
Johnny pushes his fist sized tip into Susan's destroyed pussy, and thrusted so hard into her she had no choice but to scream in pain and pleasure while she held onto Johnny for dear life.
Mary knew she was next, she was even tighter than her sister. She knew because of, "that sleepover," they once decided to have.
Even if she wasn't tighter, Johnny was a monster, and was now crushing the insides of Susan.
But Susan, was smiling! How, Mary had no idea.
"Yes, Johnny fuck me!" Susan screamed as she pulled on Johnny's spikey hair.
Johnny thrusted balls deep into Susan as her body nearly split in half.
Mary couldn't help herself, she began to strip naked and dance for Johnny, unlike Susan, she hadn't shaved and her pussy was bright red... The real fun began.
