It was 6:45 p.m., and Chesterton was preparing to close up for the night when he heard grunts and loud steps coming toward his door. Suddenly, two people burst in. It was Daniella and Tom, the two teenagers from earlier in the day.
"That was quick," Chesterton replied with glee.
Daniella walked up to him.
"Make us adults, please." Daniella whimpered.
"We'll do the gender swap thing," Tom added. "We want this so bad."
With that out of the way, Chesterton walked to his desk and picked up a knife. He had places to go and people to see, so this needed to be quickly. Chesterton asked the two teenagers to hold out their palms.
"Blood for blood" he added. Daniella and Tom each held out their hands nervously. With two quick strikes, Chesterton slashed each of their palms. The teens recoiled and screamed.
"What the fuck man" Tom shouted.
His pleas were ignored. Chesterton pulled a blank scroll from his pocket and using the blood dripping from the knife, quickly drew a pentagram on the scroll. He picked up a lighter from his desk and lit the scroll on fire. The ashes rested gently in his outstretched hands.
"Place your hands together," he beckoned. "This is a communion for life and all that comes after. Do you want this?"
Daniella looked at Tom nervously. Taming her nerves for a second, Daniella held out her hands. "Yes, I want this." Tom followed likewise. "I want this." The two teens gripped each other's hands tightly.
"I love you Daniella"
"I love you Tom"
Chesteron walked over to them. He started chanting in Latin, with his eyes turning dark red. "Sanguis in sanguine et. Novus in igne laudare carnem vana Dei." He then blew the ashes in his hands towards the teens.
The ashes whirled in the air and came together on the ground encircling the teens. Suddenly, the ashes sparked, lighting a ring of fire around Daniella and Tom. The fires shot ten feet in the air, creating a wall of flame, and their clothes vanished.
Daniella and Tom started screaming, unable to let each other go or move. Sweat started pouring profusely down their bodies. Daniella started to feel her body rumbling. Tom could barely concentrate on his partner as he was in agonizing pain himself.
Daniella thought she was levitating above the ground, only to see her feet firmly planted. She asked herself if she was getting taller only to become quickly preoccupied with the fact that she seemed to be gaining weight. Her thin legs started to stretch outwards, ripping the seams on her pants. Her hips seemed to firm and her shoulders pushed outwards. Daniella could see her arms start to get longer and thicker. Suddenly, she felt a twinge of pain in her chest as her A-cup breasts vanished into masculine pectorals. She could feel her face start to change, as she felt the flesh on it start to firm and roughen, and her voice deepened.
Tom felt himself shrink even as he grew older. His skin seemed softer all over, and he felt his hair on his head lengthen as that on the rest of his body almost completely vanished. His scrawny frame started to become curvaceous as his hips widened and his butt enlarged. Tom looked down and noticed he was growing breasts. "Fuck yeah," he briefly shouted, before being startled by his new, higher-pitched voice.
The ritual then seized their sexes and finished their reversion. They both felt their old parts lose their functionality as Tom's shaft sank into his body and his balls were sucked inside her, while Daniella felt her vagina seal up and become a sac which two mounds then moved into. Tom's emptied scrotum reformed into lips as a vaginal slit formed inside her and Daniella's clit engorged and swelled into a thick penis. For a moment before fainting, they looked at each other not focused on how they had transformed into adults, but on how one of them had gone from a boy to a woman and the other from a girl to a man.
