Daria pushed some boxes of clothes out of the way, trying to get the new apartment cleared enough to live in. She and her younger sister, Lily, had moved out of their mother’s house. This tiny apartment, if you could call it that, was all they were able to afford on Daria’s salary. Lilly was a freshman in college with a part-time job they paid little more than minimum wage. They were lucky to find anything to rent, but they had to get out of that house.
Their mother, Amelia, had gaslighted them and manipulated them into sexual scenarios. The last straw was when naive Lily was convinced to allow their mother to fuck her. Daria had rescued Lily, but not before Amelia had put a baby inside her. That’s not all Lily had gotten from her mom. Somehow sexual intercourse had made Lily’s clitoris grow. It was like it was a tiny penis.
That shouldn’t be possible. Futanaris were born, not made. The incident coincided with a similar situation Daria had witnessed in the park. A woman there had the same experience that Lily had. Other events that had been occurring. Futanari had been experiencing penis growth to amazing sizes. It had happened to Amelia. When Daria and Lily had fled, Amelia’s dick had to have been at least two feet long. Daria’s own member was 10 inches. Daria was normally around three inches long, but each orgasm had caused it to grow. This was normal, except for the magnitude and speed with which it was happening. It should have taken a year of having multiple orgasms each day for a futa to get that long. It had happened in just a few climaxes for Daria. Something was very off. She wondered if Amelia had been drugging her somehow.
The apartment had a living space with a sink and stove, and a bedroom. A tiny shower and toilet were crammed together in a bathroom that had two doors, one into the bedroom and another into the living space. There was no room for a couch in their new home. Lily and Daria were forced to share a twin bed. They had opted not to get a double bed in order to have a little more space to move around in. The sleeping situation was bad. Daria’s sex drive was overstimulated by a considerable amount. Lily’s had become even more so since she had become pregnant.
Daria had begun having sexual fantasies about her sister a few days before the two of them moved out. Daria couldn’t explain it unless Amelia had been behind it somehow. Lily had been seduced by their mother, so similar thoughts must be happening to her as well, Daria thought.
At night Daria made certain to face away from Lily, but Lily would often spoon her. Daria couldn’t protest when there was so little space to sleep. Daria didn’t normally wear pajamas, but she had been lately. Lily’s hands moved around in her sleep. Every touch was electric to Daria. Even a brush of skin against skin sent thrills through her. Lily’s breath on her neck made Daria long for her sister to kiss it. Last night Lily’s arm draped over Daria’s arm. Lily’s hand swayed back and forth with the middle finger brushing Daria left nipple through the fabric of her top. Just that light touch had kept Daria in pleasure. Daria believed that she could have climaxed from the little bit of contact, if she had been inclined. Daria also had been wondering if Lily was actually asleep the whole time. Was some of the movement purposeful?
Adding to Daria’s struggle was Lily’s wardrobe. Amelia had prompted Lily to dress more and more provocatively. Lily had grown to like it. Daria discovered that Lily had mostly taken the newer clothes when they moved out of the house. New Orleans was so hot and humid that dressing lightly was one of the few ways to survive the heat. Sweat didn’t evaporate, it just coated you in an extra layer of insulation. Still, Lily’s clothes were scandalous to Daria. The shorts she wore showed the bottom of her butt cheeks. Her tops were either tight and thin, or were loose with plunging necklines and arm holes. Lily wore a bra, but her itty bitty A cups didn’t need support. The bras were often barely there.
As Daria pushed some dishes into the few cabinets they had, Lily returned from her morning run. The door opened and Lily bounded in. She had a sports bra on, soaked in sweat. It was transparent enough to make out the size of Lily’s areolas. The shorts might as well have been bikini bottoms for the amount of body they covered. They were so tight that Daria could see not only camel toe, but the bulge of Lily’s new nub just above it.
“Oh my God. That’s what you wore running through the neighborhood?”
“I knew you’d say that.” Lily moved over to the window air conditioner. The cold air made Lily’s nipples stand up, creating tiny tents in the bra. Lily stretched her arms and legs as she cooled off.
“People can see right through that.”
“No one cares.” Lily peeled off the bra. It didn’t come off easily, sticking to her chest and back.
Daria turned around, trying to find a task to distract herself with.
“You’re afraid of seeing any of my skin, since the incident with mom.” Lily walked away from the window, wadding up the bra in her hands.
Daria didn’t know what to say. She couldn’t admit the truth. “It’s not proper for grown sisters to see each other naked.”
“Proper?” Lily laughed. “I’ve never heard you say anything about being proper in my life before three weeks ago. You’re afraid you will become attracted to me, like mom was.” Lily was standing directly behind Daria now. Daria could smell her.
“Well, we shouldn’t take a chance. We have to make certain all that degusting behavior is done with.”
“You wouldn’t be worried about it unless something already happened. Did you feel sexually aroused when you were watching me and mom?”
“Uh ... no.”
“The fact you can’t turn around and your slow response tells me your lying. It’s OK to have feelings. When I was trying on bikinis in the living room that day. I hoped you were looking at my body. I wanted you to find me sexy.”
Daria turned her head back. “What?” Daria couldn’t resist glimpsing at Lily’s chest. The nipples were wrinkled and erect. Daria’s chest reflected the light from the curtainless window. Each shift in posture changed the angle of the light, accentuating her lithe form.
“When mom was stroking my body on the couch, or undressing me, I pretended it was you.” Daria turned around to face Lily, her eyes incredulous. “Mom was manipulative and demanding. You were protective. Mom wanted to use me. You wanted to help me. Even now, you don’t want to look at me out of fear you’ll do something you don’t even wat to do.”
“This is Amelia’s doing. She put ideas in your head.”
Lily’s gaze never left Daria’s face as she spoke. “I’m a grown woman. I make decisions for myself. I’m not a child, even though you think I am naive. I’ve always felt close to you. I wanted us to have a better relationship, but you were always busy. Now, mom screwed up everything worse. I hate her. I wish this was your baby inside me instead of hers.”
Daria couldn’t believe what she had heard. She wasn’t surprised that Lily hated Amelia, but why would she want Daria’s child inside her? She couldn’t understand. “Lily, that’s a weird thing to say. You should wish you weren’t pregnant at all, or that it was a baby with someone you loved.”
“I do love you.” Lily said taking a step closer.
“You know what I mean. A partner, or a husband. That growth you have is influencing you, just like my penis is influencing me. It’s something that has happened to us. This isn’t normal.”
“So you have felt an influence.” Lily was too close now. Her sweaty stink should have been repulsive, but Daria was breathing it in. The heat radiating from Lily was noticeable. “And it’s not a growth; it’s a penis, just like you have, but smaller. I’m a futanari now.”
“No, you’re not!” Daria exclaimed and shifted herself to the corner of the counter that was supposed to act as their kitchen. ‘Futanari are born. You can’t make a woman become a futanari without medical intervention.
Lily rolled her shorts down her legs. “Look at it. It looks like it’s halfway to being a penis. It’s not just a large clit. My clit was barely anything before.” Daria saw Lily had a few days of hair growth on her crotch. Shaving was hard to do in such a tiny space. Lily took a step toward Daria again, trapping her in the corner. “I don’t care about being different now.” She said as she touched Daria’s shoulder. “I’m just glad that I am with you and we can be more open now.”
Lily’s face was close to Daria’s. Did Lily want her to kiss her, or was it hormones trying to make her think that? Every nerve was alive, seeking contact. As Daria stood motionless with indecision, Lily moved her face even closer. Her mouth opened slightly. There was no doubt now what Lily intended. She wanted physical love from her sister. If Lily hadn’t been pregnant already, she might have willingly become so right now. Daria wanted to give Lily what she wanted so much. Daria wanted to close her eyes to help her think, but she knew if she did, visions of her and Lily together would fill her mind, and Lily would probably kiss her.
Daria reached out and grabbed Lily’s arms. Lily mistook it for a reaction of passion, and moved her mouth toward Daria’s but Daria slid to the right, holding Lily at arm’s length. Lily’s face changed to disappointment. “This is you and mom, I mean Amelia, all over again. She gave in to her desires and raped her own daughter. Whatever you’re feeling, you need to get control over it. I know it’s hard, honey. I am here to help you.”
“Then why are you running away from me? I need my sister.”
“Not in a physical way you don’t.” Daria released Lily’s arms and backed up.
“I know you wanted to kiss me. Just kiss me! The world’s not going to come to an end.”
“Ours just might.” Daria replied. “I have to go to work.”
It was Saturday. While Daria sometimes worked a few hours on the weekend, she had cleared her tasks so they could move into the apartment. Daria had to escape Lily. She jumped in her Toyota sedan. It was like an oven, even at nine in the morning. She made her way down the narrow alley and onto the road.
All she could think of was Lily and good it would feel to touch her intimately. If she had kissed Lily, the two of the would be on the floor right now, cavorting like dogs in heat. Lily’s smell had intoxicated her. Was it pheromones? What caused such an attraction to her sister that hadn’t been there a few weeks ago?
Daria pulled into a hamburger drive-through and parked. She was too distracted to drive. She was afraid she would cause a wreck. She imagined Lily was with her right then, sitting in her lap, facing her, their wet naked bodies pressing together. They would stare into each other’s eyes; feel each other’s pulse. Daria could almost feel Lily’s skin sliding against her palms.
Daria’s eyes opened. She was breathing shallowly. Her dick had stretched down her right pants leg. She squeezed her left breast through her tank top. She had control of herself now. She pulled out of the parking lot and headed to work.
Once at work, she went to her laptop and began searching for information on futanari in a private web session. Most of he info was what she had read before. She changed the search to only show results from the last 6 months. She found a few news stories about futanari with giant penises, and some erotic stories about the same. Nothing said anything about women being turned into futas, or dicks growing over a matter of minutes. She and Lily needed to see a doctor. That’s the only way they would get answers. Besides, Lily needed to see an obstetrician.
Daria went shopping and ran some errands, not wanting to go home. She didn’t get any calls or texts from her sister. “She’s pissed”, Daria thought. She wondered if Lily would be there when she returned, and whether they were going to fight, if Lily was there.
