Amanda focused in and took aim squarely on Melissa’s back. She sucked in a deep breath and said a tiny prayer to herself that the gun didn’t hurt anyone. Melissa may have been one of the most beautiful girls at school, but she was also very down to earth and she and Amanda got along great. Amanda saw this as a gift for a deserving friend.

She pulled the trigger. Just as a beam of green light launched from the gun’s barrel Alan dipped Melissa in a romantic kiss that reversed their positions.

“Uh-oh!” Amanda said as she saw the beam strike Alan right in the head instead of Melissa’s back.

On the tennis court Alan had just pulled back from the most spectacular kiss of his life when he suddenly felt a crazy jolt of energy. He was so shocked by the feeling he dropped Melissa. She fell on her butt on the clay court.

“Ow! What the- Alan, are you okay?” Her anger over being dropped quickly faded when she saw Alan’s hands holding his head and an expression of pain on his face.

“I feel..... strange,” he said. “Kinda, heavy.”

“Sit down, before you pass out!”

“No, I’m okay,” he appeared to be regaining his composure. “I’m so sorry, did I hurt you?” Alan offered his hand to help Melissa up.

She didn’t take it, instead she was just staring at him.

“What? What’s wrong?”

“Alan, look at yourself. What’s happening to you?”

He looked down. He had always considered himself an athletic person, but never anywhere near this level. His body was swelling with muscle. His cotton polo shirt was plastered to his enlarging chest. The buttons at the neck had already pulled apart and were separating further. A few moments later he was unable to see his body beyond his swelling chest and shoulders. He brought his right arm up and flexed his biceps. His short sleeve split in two up to his shoulder as the peak of his twin muscles rose higher and higher finally topping out at an incredible 27“.

Moments later the mysterious growth stopped and Alan was left taking stock of his new body. He would have been the envy of bodybuilders everywhere. He must have weighed well over 300 pounds, maybe even 350. No man had ever achieved such size. Melissa was examining him closely as well, but her focus was on his lower half. His shorts were plastered to enormous thighs that defied description. And poking out of the bottom of his shorts was the length of hose that was now his penis. Flaccid it looked to measure nine inches at least. As if it knew she was looking at it his cock began to fill with blood and grow hard. Thickening it, at first, slid further down Alan’s thigh towards his knee, but it soon became to strong for his flimsy shorts to contain it. Ripping through the fabric it stood at full attention it was just over a foot and a half in length and as thick as Melissa’s arm.

His hands reached down and grasped his mighty shaft. Alan then looked down at Melissa and smiled. “Now,” he said, “where were we?”

“Are you sure you’re okay?” she asked standing up once more.

“Baby, you have no idea. I’ve never felt better.”

Melissa felt a familiar tingling in her sex. In one swift move she leapt up and wrapped her long legs around Alan’s middle and came to rest on his cock like she were sitting on a bicycle seat. His steel rod held her weight with no trouble. His strong hands moved down her back and under her short skirt. In one quick move he ripped her panties off. She let out a quick gasp of surprise then melted forward and began kissing his huge chest.

Alan placed one hand under her bottom and lifted her up so that her face was even with his. As they locked into a deep passionate kiss he marveled at how easy it was to hold her. He didn’t know just how strong he was, but he felt like he could stop bullets if he wanted. He adjusted the hand that was holder Melissa so that his fingers were at her vagina. In one quick move his middle finger was inside her and pumping in and out. His other hand moved over her body like a snake; feeling her back, her neck, grabbing her hair, holding her close.

Melissa began panting. She couldn’t believe how strong his fingers were. In mere minutes she was coming and screaming. Her juices flowed down and over his hand, but he didn’t stop. He began fingering her harder. She began to help him by bouncing up and down on his hand.

Orgasm after orgasm ripped through her body like a freight train. Melissa felt lightheaded and began to go limp in Alan’s arms. He stopped his ministrations and, very gently, set her down on the warm ground.

Her body was covered in a slick layer of sweat. Her shirt was plastered to her torso and the outline of her pert breasts heaving up and down with each breath was clearly visible.

“What...what...happened?” she she panted.

Alan placed his hands on his hips and flexed his chest and legs to unbelievable size. “I don’t know,” he said, “but I hope it lasts. I love it.”

Across the street Amanda was watching the whole scene. Seeing the way that Alan was able to manhandle Melissa had turned her on incredibly, and just had only set the gun to 20% power. What would 30% do? Or 50%? She was afraid to think of what 100% could have done. This wasn’t exactly the result she had planed, but they seemed happy. Now she had to decide what to do next.
