iBod - A Life Changing Music Player

"I'm perfect." Aaron thought "but why did this happen to me?"

She reached up to cup his impossibly large and firm breasts. They seemed to be floating on his chest, with very little sagginess. She grabbed and groped her heaving orbs tenderly, and forcefully. Aaron would have killed to fuck a girl like this when he was a man. She sashayed, and swayed her hips and shook her breasts, emphasizing her sexiness. Again, feeling a quite horny due to the recent turn of events and this display in front of the mirror, she reached between her legs for another session. As she did, she heard the front door click open, and a mischievous smile crossed her face.

---

After Seth had walked in and clinked his keys on the front hall table, he called out: "Aaron? You home?"

Looking up, he saw a fully nude, gorgeous girl step out of Aaron's room. She looked like many a hipster woman that Aaron had managed to drag home after late night concerts. This one however was eyeing him with flames of lust in her eyes.

"It's Erin, now, with an E." she said, giggling. She smiled and slowly glided over next to her target. "I want to thank you for treating me so nicely these last few weeks, even though I've been a bit of a screw up sometimes."

Seth was frozen, but honestly a little aroused. "What the hell. You're a girl now?? What, how?"

"Shhh," she said, placing her slender finger over his lips. She reached down and rubbed the growing bulge in his pants. Removing her finger from his lips, she placed it in her mouth and started to slowly suck it, in and out, moaning as she did. Then she slowly guided him back to the overstuffed sofa, and pushed him onto it. She quickly removed his belt and unzipped his pants, carefully avoiding touching his penis, something she knew would be absolute torture. She wasn't sure why this uncontrollable lust had made this feel so natural, but right now she just wanted one thing, and she was going to get it.

Yanking his pants, off, she grabbed for his rock hard cock. She licked it slowly from the bottom to the top, coating it with lubrication, maintaining eye contact with him. She lightly sucked on the head, swirling her tongue as she did. She then swung her heavy tits over his cock and and lightly brushed it with her nipples and warm curves. She wrapped her soft tits around his cock and slowly stroked, up and down. Seth, who had not had any action since his girlfriend Stephanie moved out several months ago, was in absolutely heaven. As Erin continued her warm-up exercise, she took one of her free hands and began to tease herself. First she gave her dangling breasts a hefty squeeze, then slowly trailed down to her new sex. She encountered a very swollen and wet vagina, and after coating her fingers in lubrication, slowly finger-fucked herself while using her other hand to work his shaft. She thought it wasn't quite the biggest thing she'd ever seen, it was about average at 6.5 inches or so, but it would certainly do for what she needed it for. She worked him and herself to the edge, but when she felt him about to cum, she immediately slowed and removed herself from his cock, letting her drool run down from her mouth, gasping and smiling. She stroked him slowly and began to move herself into position on top of him.

Suddenly her wrist screen lit up, and beeped with the message "Receiving new data!" Her breasts then began to swell, very slowly at first, and the two barely noticed what was happening. They moved from a DD to an E over the course of about two minutes. Erin was frozen in the pleasure of the growth, and was just a few inches from impaling herself on Seth's cock. Seth lay back and watched the spectacle, while Erin was still slowly stroking him and feeling her breasts. Erin slowly snapped out of it, but felt even more turned on than before. She reached up and cupped her new additions, and moaned at their new sensitivity. She then looked back at Seth with a lustful fire in her eyes as she slowly rubbed the head of his penis around the opening to her new vagina, coating it with her wetness.

After a few seconds of torture, she slowly worked herself down onto his cock, and almost came right there. She enjoyed the feeling of being filled completely. She worked herself up and down on his shaft, moaning and gasping for air. Her enormous breasts were bouncing and jiggling all over the place. She reached up and grasped one and her hand sunk into its heavy mass, squashing it into a perfect circle. When he sensed she was getting too tired to keep up her feverish pace, Seth flipped her over and held her legs high in the air so that they rested on his shoulders. As he re-entered her she almost screamed in pleasure. Her hands were now free to tease her clit and massage her tits. She couldn't believe how good it felt to be filled to the brim with his cock. He continued pounding her moist pussy, until he started to reach the point of no return. Luckily, Erin was almost on the edge as well.

"Erin. I'm going to...uh" gasped Seth.

"I know, I can feel it.*UH* Oh god I want you to cum inside me so badly. Please, just cum inside my *UH* little *UNH* *AH!* PUSSY!" said Erin, through gritted teeth, in between collisions.

With that, Seth exploded inside her, coating her insides with his seed. When Erin felt him expand inside her, she too erupted in a powerful orgasm. Both of their orgasms seemed to go on for minutes, and after they had died down they collapsed on each other, gasping for breath and feeling each other's heartbeats.

"Oh my god, I had no idea it felt like that for a woman," mumbled Erin, in a post-orgasmic haze

"Yeah, that was pretty amazing, I have to say." whispered Seth, as he admired her flared hips, flat stomach and beautiful tits, all coated in a fine mist of perspiration.

After a few minutes of casual stroking of each other's bodies and the catching of breath, the weirdness started to set in.

Seth sat up on his side and admired his conquest "So, uh, what the hell happened to you. I haven't seen you in two days and suddenly you're some sex fiend with gigantic tits and some sort of bionic arm attachment?"

"Yeah, it was that music player beta test thing that i signed up for. Apparently it stores music data inside special cells in your body, and knowing the size of my library, that sort of accounts for these." said Erin, cupping her perfectly round breasts.

"Ok, that sort of makes sense, but how does that account for you suddenly being turned into a girl?" asked Seth

"Well, I think what happened is that some of my music library had been corrupted by some sort of virus, and that had somehow messed up the uploading process. As the music uploaded to me over a couple sessions earlier today, I found myself looking more and more like a girl. I was definitely scared about what was happening to me, but at first I passed it off as my imagination. By the time I realized it was something serious, it was too late and I just sort of lay back and let it happen. All of these new sensations made me incredibly horny though, and I was desperate for something to help vent my needs, man or woman, and thats when I heard you come home."

"Well, lucky me, I guess we're going to have a lot of stuff to figure out now. I mean, what you have could be reversible if you wanted to change back."

"Yeah, thats true, but in a weird way this all sort of feels right to me. And this body, oh my god," she said, shivering with disbelief "It just feels built for these sensations. I don't think I would enjoy sex as a man as much if I had to go back. Plus we've been friends for so long I know it will be weird for a while but I'm still the same person, just with a different set of equipment"

"All right, whatever you want to do, it's up to you. I'll find a way to support you until you get this all sorted out. I know you were on the job hunt but this whole gender switch might put a monkey wrench in the system for now." said Seth

"Thanks. I'll have to see if i can get some sort of compensation from the company for what's happened. I hope I didn't sign my life away somewhere, speaking of which, I should probably go check on the software. I'm not sure why my tits started growing a few minutes ago, but I definitely don't want them to swell every time I get some new automatic file update. They're big enough as it is."

"Couldn't you just delete some of your music?" grinned Seth

"Hah, what are you, crazy?" she said, shoving him down on the couch

With some difficulty, Erin got up on wobbly legs and walked back to her room. She searched the iBod software for wireless update information. Apparently she could receive new music from artists based on her current library information. Updates would progress slowly as the library was culled for matching data.

"Hm. I guess I can't say no to new free music, but do I have to get enormous boobs at the same time, ah-ha!"

She found a small tab in the wireless updates section of the software and it said data location: "Localize" or "Re-Appropriate." Localize was checked, so that must've been why only her breasts had grown over the last few updates. She checked Re-Appropriate and a message popped up saying that this would only affect future updates. She clicked ok and closed the window. She then went out to take a shower.

As she washed herself, she reveled in the pleasurable sensations of the water hitting her large chest. She soaped up her tits and groped them, feeling the slick flesh slide from between her hands. Once again she was getting quite turned on by these new sensation. As she reached down between her legs, she didn't notice that she was receiving a new wireless update, but this time it wasn't her tits that grew, it was something else.

As she stepped out of the shower, Seth walked by the open door and stood there admiring her. She looked a little different however, maybe a little pudgier around her stomach, but it could have been the angle. The fear of pregnancy quickly crossed Seth's mind. They definitely hadn't used protection, but was Erin really all girl down there? Maybe he had some more updates to finish the pipes all the way through.

As Erin finished toweling off her hair, she caught him staring. "Hey you, take a picture it'll last longer." she giggled

That night they slept together once again, this time was even better than the first, and Erin began to see herself missing her male self less and less. They fell asleep on each other, gasping for air, and completely satisfied. Over the night, Erin continued to receive more updates from the computer as it processed her library, and found more music to match her tastes.

In the morning, Erin was awoken by the sunlight streaming in Seth's room, she shifted a bit to cover her eyes and immediately felt something out of place. It wasn't her tits, it was...

"Holy shit! My stomach!" she yelled, tossing off the covers.

Seth quickly sat up and saw Erin groping her swollen belly in disbelief. She looked 6 months pregnant. Everything else looked the same, but she had a perfectly round, pregnant belly forming where her once flat, chiseled abs had been.

"Oh my god, are you?"

"Pregnant? Jesus, I hope not. It doesn't happen this fast does it?"

"Who knows what that music player is doing to you, it seems like anything could happen at this point."

Seth reached over to stroke Erin's swollen belly. The skin felt so smooth and warm. The flesh had a bit of give to it, but not in the same way as if it were regular fat. It was firm, taut but still soft and yielding. Seth could feel himself getting hard.

"You know, I haven't told anyone this before, but I sort of have a thing for pregnant girls. Something about those fertile, swollen bellies just really turns me on, kind of like this one is doing right now." said Seth, smirking

"Ugh," said Erin, pushing Seth's hand off of her, "I can't believe you're saying that right now. This is serio...OH!"

She was suddenly racked with pleasure. She leaned forward to clutch her belly, just in time to feel it start slowly growing beneath her outspread hands. Her wrist display was saying that another wireless update was being received, but she was enjoying the swelling sensation too much to notice. Her fingers slowly spread apart as her perceived pregnancy advanced another month. As the swelling slowed, she reached down to her now drenched pussy and began to slowly rub it, while using her other hand to grope her bloated abdomen. Seth watched this series of events and had reached down to stroke himself. Erin then looked over at him with incredibly intense bedroom eyes, her hair falling over her face. She hefted her weight and tackled him onto his back. She positioned herself over his throbbing cock, stroking the length of her ripe belly along the head until she was ready to sink down onto it, using her extra weight to her advantage.

"Unh! Oh god, baby, you feel so good inside me - mmmm." Erin moaned.

As she came down she felt Seth's rod dive even deeper to her than it had yesterday. She assumed it was because of the extra gravity she now possessed. Rational thought soon escaped her as she began to move faster and faster on his shaft. She could feel every inch probing her insides, as she pumped up and down, and rocked back and forth. One hand was on her swollen clit, and the other was massaging her huge tits. Seth was excitedly exploring her round belly, when suddenly her moans intensified.

"Ohhhhh, ohhhhhh, it's happening again! Oh jesus!" she screamed, her speech stuttered by the slapping of her fat tits against her chest

"What? What do you mean??" asked Seth, alarmed.

His question was soon answered as he felt the flesh between his hands start to expand, filling his palms even more. Her motions were feverish as the swelling continued. Over the course of the last minute she had passed from looking 7 months pregnant to looking overdue with twins. The pleasure of her growth was unimaginable.

"Uh, not to alarm you but it's starting to get a little hard to breath down here, although it is a fantastic view," panted Seth.

She submitted reluctantly and rolled onto her side. Seth dragged her to the edge of the bed so that he could stand and fuck her, with her plump belly laying on top of her. She explored her unbelievable size with both hands, moaning as she trailed her hands over the great expanses of flesh. Seth continued pounding her, one hand on her belly to steady himself. He could sense the point of no return, and Erin was nearing a long delayed orgasm of her own. They sped up their pace, and all at once a massive orgasm came crashing down on Erin.

"OH MY GODDD...OH OH OH..FUCK ME SETH..CUM INSIDE ME ..FILL ME...OH...AHHHHHHH," she screamed at the top of her lungs.

Once again, Seth shot his load into her waiting womb, and experienced one of the strongest orgasms of his life. He could swear his dick had swollen even bigger during this last encounter. He collapsed on top of her bloated, pregnant belly, his dick still twitching inside of her. They took a few minutes, basking in eachother's bodies

"Whew, geez, I just can't control this body. It's so tuned for these erotic sensations. Once my stomach started to swell, I just had to have you inside me. Look at me now though! I'm as big as a house. Can you help me sit up?"

Seth helped her rock forward into a sitting position. Her massive middle completely filled her lap, and her ripe breasts rested on top of it. She wouldn't be seeing her feet again for quite some time. She sat there for a minute, rubbing its gigantic size, pondering the current state of affairs.

"I wonder if I'm stuck like this. The documentation said the swelling would be exaggerated in the first few days of data storing, but that it would eventually subside. I'll have to check and see if I can do something about this thing from the software though."

"Can you check and see if this shit is contagious somehow? I could swear my dick is bigger," asked Seth.

"I thought I noticed that too, but hey.I'm not complaining," she smiled back.

She stood up on wobbly legs and slowly waddled, still naked, back to her room, adjusting to her new center of gravity. She plopped down into her chair and began clicking through the options. First she returned to the menu that caused all of this trouble. She tried to change the option of re-allocating her data, but that option was locked for some reason. She did decide to disable wireless updates for now though, just to avoid any future mishaps. She then checked the documentation for any signs of contagious data. It did warn that sexual intercourse could spread data in the early days of using the product, but it would be on a small and harmless scale. Satisfied, she struggled to stand up again. She caught herself in the mirror and admired her body. She gazed at her impressive, fertile curves, and felt very womanly and very sexy. She then wobbled back to Seth's bed, enjoying the bouncing sensations of her breasts and gigantic stomach as she walked.

"I should be done with swelling for now, and according to the documentation you should be too. It said sex can spread some of the data for growth, but it should be nothing to worry about, especially if it means I get a few more inches to fill me up." she said, seductively caressing her stomach.

Seth pulled her forward for a kiss, and the shift made her fall over on top of him, pinning him.

"Hah! i got you right where I want you, now, let's inspect these 'side effects' further shall we?" Erin said with a grin.

--

Two months later.

--

Erin awoke slowly as she heard Seth leave for work. As she rolled over in bed she put on some good early morning music with her iBod, and thought about what had transpired in since she had received that fantastic device.

Seth had eventually convinced her to contact the iBod manufacturers and tell them what had happened to her. They were incredibly surprised that such a drastic change had taken place and asked if she was sure that all of her files were clean. When she told them about the infected files, they were still pretty surprised, but had resisted saying that it was their fault. They had clearly outlined that files must be clean before uploading into one's body and that the consequences of using infected files were unknown. They did eventually concede to a quiet, but hefty settlement for Erin, so that she would keep her story quiet for a while. With this money she was able to stay with Seth and handle both of their rent's for as long as they needed until they figured out what to do with her. They also pointed out that the swelling she experienced would soon be significantly lessened once they released their data compression patch for the software.

She lay there absentmindedly stroking her tummy. It was no longer the gigantic thing it had been a few months ago, but she didn't have the flat stomach she had started out with either. It was still slightly swollen and a bit pudgy, but Seth still found her incredibly sexy. Her breasts had not decreased in size too much, maybe down to a D cup but she didn't wear bras (or clothes for that matter) too much to notice.

Suddenly, she was hit with a wave of nausea.

"Ah god, not again. This is the third time this week!" she thought, leaning over the bowl

When she returned to bed she hoped she wasn't getting sick or something like that. She wiled away the rest of the day in bed, resting and watching TV, and occasionally masturbating when the need struck (as it still often did).

In the evening, Seth returned from work carrying a small drugstore bag.

"Hey, how were you feeling today, any better?" he said, kissing her on the forehead.

"Well I threw up again this morning after you left, but I've been feeling alright since then. It seems to be worst in the morning."

"Oh, I'm sorry I wasn't around. Hey, listen, I don't want you to be freaked out or anything but I might have an idea of why you haven't felt well lately," he said pulling out the drugstore bag.
