Hormones Create a Goddess

Genevieve watched in amazement. Right before her eyes, her girlfriend's cock was actually growing! Not just engorging with blood, but growing longer and thicker. She had been told the new hormone therapy her girlfriend Tanya was trying would have some strange side effects, but this was a miracle in action.

Tanya moaned in ecstasy and fell onto their bed, her other hand reaching down to stroke her growing phallus. It was at least twelve inches now when before it had merely been four. Genevieve managed to pull her eyes away from the spectacle and saw that those were not the only changes occurring. Tanya's other hand was busy frantically groping her breasts as they ballooned outwards, too big for her fingers to contain.

Before all this, Tanya had been a fairly androgynous trans girl. Short hair, small but slowly developing breasts. Her most striking features had been her gorgeous green eyes and flawless dark skin. Other than that though she was a fairly plain tomboy.

Genevieve had always been the more stunning of the two. She had blonde hair that flowed like a river down her back, and loved to expose the cleavage of her D cup breasts in low cut dresses. Her slender legs were a sight to behold, and she loved to show them to the world with short skirts. All of the fat in her body seemed to head right to her breasts and hips. Genevieve had always been a tease, and loved to taunt people with what they couldn't have. She was proud of her looks, and her girlfriend loved her for them.

Looking down at Tanya now though, her girlfriend was now blowing her buxom proportions right out of the sky. Tanya's breasts were now easily E cups and still ballooning outward. Her cock was approaching two feet in length and was thick like a hammer. The tip was pulsing and precum left it perpetually wet. Tanya's hips had grown as well, but her waist had actually slimmed down. Her dark hair was also growing, it's thickness and volume increasing magnificently.

All the while Tanya squealed like a cat in heat. Her legs were spread wide as her massive pillar fell between her legs. When her cock hit the bedsheet a bit of precum squirted from the tip and Tanya yelled as if she were climaxing. No burst of actual cum came however, and Tanya continued to writhe on the bed, her face flush and her tongue hanging out, desperately licking the air for something to suck on.

Finally the changes slowed to a stop, and Tanya lay on the bed panting. Genevieve's jaw hung wide open as she took in the final results of her girlfriend's glorious metamorphosis. Tanya had become a goddess in her eyes. Her breasts were F cups and her cock lay erect across the bed at what must have been around five feet in length. Tanya opened her eyes and those gleaming emeralds shook Genevieve to her core.

"That... was incredible..." Tanya managed to say, her words coming in short bursts as she struggled to catch her breath.

"You..." Genevieve was at a loss for words. Tanya stood carefully. Her cock dragged along the carpet, leaving a trail of liquid with it as she walked to the full length mirror in the corner.

Genevieve was lost in the majesty of her girlfriend's new form as Tanya examined herself. She tested the weight of her breasts, and moaned softly when her fingers slid over her nipples.

She touched her cock and became weak in the knees. In an instant Genevieve was to her side, supporting her. The young lovers stared into each others eyes.

"You're a goddess" Genevieve finally managed to say. Tanya's eyes widened at the unexpected choice of words. And yet there was no denying that the words were appropriate.

Tanya leaned in and kissed Genevieve passionately. For a moment Genevieve was surprised by the suddenness, but quickly returned the kiss. The two made their way to the bed and Tanya threw Genevieve beneath her. Tanya's voluminous hair framed her face beautifully and the two lovers paused for a moment to once again stare into each other's eyes.

"Please..." Genevieve said, and that was all the encouragement Tanya needed. She pressed her new massive breasts against her girlfriend and guided the tip of her massive cock to her moist opening. She slid the massive tip in as far as it would go, but it was less than a quarter of her full length.

Genevieve laughed at their predicament as Tanya blushed in embarrassment.

"It's okay, baby" Genevieve said. "Let me worship your cock like a true goddess deserves."

Genevieve flipped over on top of Tanya and cupped the massive phallus in both her hands. She couldn't fit even both of her hands around it. Genevieve thought for a moment while Tanya groaned beneath her. She positioned herself over Tanya's stomach and decided the best course of action would be to hug the shaft. She pressed her breasts against it and tried to fit them around it as best she could, and then wrapped her arms around it.

She moved her mouth near the tip and licked it. Once again upon stimulation a quick burst of precum shot out, this time hitting her in the face. Genevieve licked her lips and then put her whole mouth around it and with her arms and breasts proceeded to move her whole body up and down the shaft.

Tanya was yowling like a cat in heat once again. The pleasure was more intense than anything she had ever felt. She was essentially wearing her girlfriend like a fleshlight. Through the haze of pleasure Tanya felt a pang of guilt that Genevieve was doing all the work. She reached her hand down and dipped her slender fingers into Genevieve's pussy. Interestingly, her fingers had also been enhanced by the hormones. They were quite longer and more dextrous. Tanya had no trouble at all teasing her girlfriend's clit and slipping two fingers inside her.

Genevieve was in heaven. The godly cock she had wrapped herself around and the incredibly nimble fingers buried deep within her had her cumming within a minute. Her eyes rolled back into her head as she squealed around the thick tip in her mouth. Tanya however wasn't finished yet.

She leaned forward from a relaxed position without using her hands with flexibility and strength she had not previously been capable of and pressed her massive breasts against Genevieve's back. She repositioned her hand for better access to her girlfriend's tight pussy and kissed the back of her neck.

"I want to shower you in my cum..." she purred as Genevieve leaned into her.

Their pace quickened. Genevieve came again and again while Tanya was still building to an epic climax. Finally, her massive cock pulsed in Genevieve's arms. Tanya screamed and fell backward as a thick load of cum visibly made its way up the shaft and into Genevieve's mouth. Her eyes widened as she saw the load coming but was helpless to pull away.

The load reached the tip of Tanya's cock and burst into Genevieve's mouth like a broken fire hydrant. She got a fill of the salty taste as it knocked her backward onto her girlfriend's pillowy breasts. Tanya's screams could surely be heard by anyone passing by as the room was showered in cum. She kept cumming and she kept screaming as Genevieve stared in disbelief at the fountain of cum that was now covering everything in their bedroom. Eventually the cum fountain died down and the cock dropped on top of them both as they lay together, covered in white fluid.

When Tanya was able to breathe again she wrapped her arms around her girl and held her tightly.

"You're a goddess to me too" she whispered softly, and Genevieve blushed and buried her face in the mountainous breasts that were now her favorite toys.

The two lay together in silence for some time and enjoyed each others company. Soon, however, Tanya's cock began to harden, and Genevieve smiled...
