Two is better than one

Diana's discomfort in her torso ebbed but the itch and burning in her crotch intensified. Nearing the end of the shift she headed to the locker room to shower and change.

Removing her jumpsuit and underwear, she entered the private shower stall and let the hot water run down her head, her bob length hair clinging to her face. She loved her life as a scientist but it came with some price to balance in her life, socially and physically. Diana wasn't unattractive for a 27 year old, but working 60 hours a week was taking its toll. She and her partner Liz, a med student, lived a happy life, but it was all centered around work and studies.

She looked down at her drooping B cup breasts, somewhat out of shape mid section and resolved tomorrow to start on that long put off workout routine. As the steaming water trickled down her body, she reached to her clitoris and began to scratch feverishly. The itching fire gave way to arousal.

The harder she rubbed the more the arousal seemed to move left. Her mons seemed to grow wider across her pubis. Reaching down with her other hand she found another sensitive spot in her labia an inch to the right. Rubbing both spots and closing in on an orgasm, the buttons expanded rapidly to two separate swelling clitorises. Creeping out, one inch, four inches, swelling defined tips arose and the appendages stopped at two feet in length, resting against the confinement.

Diana stroked furiously with both hands, bending over to reach the tips. Looking down her abs tightened, and her breasts expanded, partially obscuring the view. The cells now being repurposed to support the new organs. Reaching a double orgasm simultaneously, the phalli blasted forth, the shower stall being coated in a white goo that slunk down the wall and disappeared in the drain.

Catching her breath, Diana realized what just happened had to be related to the lab accident earlier. "Diphallia", she thought. This condition of two pensis had occurred in males throughout history at birth, but never, of course, spontaneously in a female, or to any level of endowment.

The dangling pair now having gone flaccid she found only two dangling testicles underneath and her vagina intact behind them.

Quickly drying off she peaked out from the curtain to make sure she was still alone in the locker room. Putting on her underwear and bra proved impossible. She did her best to slip on the pants, tshirt and jacket. Diana carried a clipboard in front of her to conceal the bulges above and below as she walked out to her car and drove home. "Liz is going to love this", Diana thought to herself, as her pants tightened.

The drive home was intense, with her new cocks contantly springing up and hitting the steering wheel. Arriving at home she ran inside and stripped naked in the bathroom. Diana saw the new her: two D cup teardrop shaped breasts, 6 pack abs, and twin elephant snout sexual organs dangling at her knees. She swore her brunette hair was a little longer and her features a little sexier, pouty lips and longer eyelashes. Walking into the bedroom trying to adjust her stride to the new swaying appendages, she jumped in bed and spooned in behind Liz's likewise unclothed body.

"How was work?" asked a half sleeping Liz.

Diana reached down and positioned each new appendage, one at Liz's pussy the other at her ass.

Feeling the blood rush and the erections inflate, Diana responded, "I brought you a present."
