Her first experiment ended in disaster. She had selected a large muscular male who, after being promised sex and profits, was willing and eager to participate in the experiment. After she injected him with the serum, his balls grew to the enormous size of basketballs! His 8" cock started pumping cum uncontrollably for hours! Laura called her friend Tosha, who finally castrated the poor hunk, aborting the experiment!

And now, the story continues…

Tosha quickly grabbed the muscleman hard by his balls. He was still unconscious and tied to the table. She squeezed his testicles hard, pulled them all the way down to the bottom of his sack. Laura handed her a big sharp knife, and she cut his balls off! Tosha was absolutely amazed at the huge testicles she had just severed! His large body laid unconscious on the table, muscular legs spread wide in stirrups, blood dripping from where his balls once were! His cock was still hard and spouting, as if trying to lose more sperm. But soon both blood and sperm were oozing from his cock head more and more until it was starting to spurt out onto the floor!

Laura looked frantic! “I injected too much serum! I've ruined him! Tosha, help me with him. No one must ever know about this! Or we'll both end up bankrupt!”

Tosha hugged Laura, gently kissing her. “Laura, don't worry. I'm in this now too!

Remember, I was the one who castrated him! But it did work, didn't it? You just used too much serum this time. The next one will work out ok. And I've got just the one to try next… my husband, Fritz! He'll jump at the chance if he thinks something will make his balls bigger to match that big cock of his!”

Laura smiled. “He does have a big cock doesn't he! Well, in the meantime I will make a cure to reverse the effects so we don’t have another disaster like this one!”

Both women turned and looked at the cock that was now starting to droop and was still dripping blood and cum. They started laughing hysterically at the now ruined genitals. What a situation they were both in now! Laura picked up the sharp knife and to staunch the blood flow, she cut off the bodybuilder’s penis! His shrunken severed cock and balls were evidence, so they took turns stomping them into mush in the ground with their high heals, and then buried the destroyed genitals in the backyard. Then they bandaged up the tiny stump that was left on the big male, untied him from the table, and dragged him out to the car. They drove him to the hospital far out of town, and left him at the entrance, nude and castrated.

Tosha went home that night and made love to her husband like a woman possessed, riding him with visions of castrating that hot sexy bodybuilder! As she had done earlier that night, in her mind’s eye she could hear the big heavy testicles drop to the floor and the last rope of cum shooting from the big male’s cock!

She climaxed as never before, as her cunt massaged her husband’s cock. Tosha rolled off her husband’s 10" cock, which was still throbbing hard. Breathing hard, she reached between his thighs and gently grabbed his balls. She whispered, “How would you like having balls five times bigger then these?” Tosha then explained her friend Laura’s new serum, and the purpose for which it was to be used.

Fritz, being a typical middle-aged, unattractive, and out-of-shape male, agreed almost immediately! The thought of being hung like a bull was all he needed to say “yes!” Tosha then held his balls. She grabbed the base of his cock and started sucking. Immediately his cock exploded in her mouth. Milking his balls dry, she thought about how much he would be able to produce after the injections.

That morning, Tosha took Fritz to Laura's office. They both knew each other so it was a completely friendly setting. Laura said, “I guess Tosha’s told you everything. So let's get started! Take all your clothes off, and let's see if you’re as big as I remember!” She said with a big smile, looking over at Tosha.

Fritz stripped immediately, as the two women watched. He was pale and pasty and thin, but with some flabby fat sticking out from his belly. Laura stepped forward and lifted his limp cock up and out of the way and started examining his balls, feeling their firmness and weight! His cock grew immediately at the soft touch of Laura's hand, and she fondled it playfully, saying with a laugh, "you naughty boy, you!” Laura winked at Tosha. Then she went to a tray that held a hypodermic needle and her serum.

“Tosha, hold his balls up. Push them to the bottom of his sack so they standout prominently.” Tosha held her husband’s testicles, gently pulling them up. Fritz let out a sigh of pleasure. Laura turned with the syringe and injected his inner crotch. Laura looked at Tosha with a smile, as Fritz asked to be pleasured some more.

But Tosha almost felt disgusted by her dirty, smelly husband! She watched him grab his balls in an obscene way. But she could also see them enlarging, and both women watched in fascination as they swelled, stretching the sack that held them!

Fritz was moaning loudly now, squatting low with his knees spread wide to accommodate himself as he felt his testicles starting to rest on the carpet floor! Suddenly his cock reared and a long rope of cum shot out from under him with such force that both women stepped back, surprised at the sudden discharge! Laura knew immediately that she had succeeded as she bent down and watched his cock strain and rear again as another long rope of cum discharged from the big member! Tosha immediately grabbed a bowl and slid it under her husband cock just in time to catch another load. He was starting to get weak, moaning and trembling as he let loose with another load of cum, then collapsed lying in his own mess! His now huge testicles, looking like two haft inflated beach balls stretched in their sack, rested nearly down to his calves!

Laura felt him for a heart beat, then told Tosha to help her roll him onto his back. Both women strained to roll the flabby, overweight, 200lb fat man over! Laura thought for a second. “Help me drag him to the next room and into a bed. Then we'll clean up this mess, and him too!” Tosha started cleaning the mess, as Laura went and got champagne to celebrate, and also to change into something like only her black high heels and an open lab coat. Tosha, hearing Laura’s high heels clicking towards her, looked up. Laura swept the lab coat open and rested her hand on her hip. With a big smile, she said “let’s celebrate!” Tosha slid her hand up Laura’s inner thigh to her pussy! Then gently she pushed a finger into Laura’s pussy and then kissed her.

“Let’s do it with Fritz too!” Laura laughed, as Fritz began to regain consciousness.

“Not my thoughts, exactly, but it is a celebration, so why not?” Tosha gave in. So, Laura and Tosha made love with Fritz and each other in a threesome for many hours, as they played with his enormous balls and still hard cock. As he breathed heavily in a restless and endless orgasm! The next morning they all awoke naked in each other's arms! Fritz went to sit up on the edge of the bed, his huge testicles hanging between his legs just inches from the floor. Tosha could see that he was still in a lot of ecstasy, but his ball sack was stretched to the point of possibly tearing! While his large cock was still erect!

He looked over at his wife and Laura and said, “I can't walk! I tried but there's too much weight and I can only carry one. You need to help me, Tosha!” Laura got up and left. She came back with a small medical table with wheels. Fritz watched Laura’s lean naked body, and his cock reared up and a long rope of cum shot out across the room!

“Tosha let's try to stand him up and to put his balls on this cart.” Though disgusted by her husband and not wanting to touch his ugly body, Tosha helped Laura, and they both grabbed him under his arms and helped him to his feet. His legs were spread wide, as his balls swung back and fourth like two enormous pendulums! Pulling the cart up close, both women grabbed a ball and lifted it onto the cart. But as soon as they touched them, another long rope of cum shot out from Fritz’s cock and all over the two women!

“Enough!” cried Laura. Then she injected another experimental serum but this time the reversal one, into Fritz’s buttocks. But not too much, because she didn’t want to cancel the first serum. Then Fritz’s testicles began to shrink very quickly until they were just one quarter the size before, but they were still two times bigger than a normal male’s! Now Fritz had an enormous 10” cock and two orange-sized balls! He was the envy of every man! And now, even his wife Tosha wanted him! But she still shared with her best friend Laura, so every night they had wild threesome sex. Fritz was the luckiest and happiest man in the world! And soon they would all be rich.

The End
