Chapter 2-Expanding horizons

Lynn

Lynn made her way up the final steps to Issac's dorm. The steps were no issue due to her consistent workouts, but she just hated coming to the men's dorms in general. She would always get catcalled and leered at as she passed by. But regardless, she could always count on Issac to get her notes she needed, so she had to come here. School had just become such a drag lately, she much preferred spending her mornings doing yoga and meditating. Her time sense her breakup had been so nice to focus on herself, something her ex never seemed to let her do. He always wanted her to be doing what he wanted, being with him at all times and always supporting him 24/7, regardless of her own commitments. But now she was on the right track to something nice.

As Lynn was walking down the hallway, a warm feeling suddenly rushed through her whole body. Lynn, fell against the wall slightly to catch herself.

What was that?!

she wondered. It didn't feel bad, it actually felt pretty good. It was just so sudden and so unexpected, Lynn tried to place what could have caused it, but couldn't. Best she could guess it was her muscles relaxing after all those stairs. No matter, she had to go get some notes from... Issac. She suddenly quickened her step. She realized how much she wanted to see him, which had never occurred to her before but it made sense. He was honestly pretty hot and fit, even though she never saw him in the gym, and was always super nice to her. It was a wonder that she hadn't found more excuses to come see him.

"Why was that?" she pondered.

She was so lost in thought she took a few steps past his room before realizing she was about to pass it. She corrected herself, and took a moment to make sure she looked nice for Issac via her phone before knocking. Her brown hair was in a high and tight pony tail, as it always was. Easiest during workouts and running. She also admired how cute her natural features were. Again, no make-up was simply easiest when you're getting all sweaty. She unzipped her jacket to expose her sports tank top a bit, and adjusted her bra. She normally kept it tight so her boobs didn't bounce during her workouts, but it was getting tighter than usual.

Maybe it's time for some new bras

, she thought as she knocked on the door. Almost immediately, Issac opened the door.

"Hey Lynn, nice to see you, come on in," he said, simply opening the door and turning back to his room. "I can't seem to find my notes so you can chill for a bit while I look around."

Lynn just planned to chat in the doorway a bit so she could actually study the notes, but hanging out a bit couldn't hurt. Especially after Issac invited her in, it'd be so rude to just ask for notes and leave. Besides, she could already catch herself staring at his muscles, poking out the edges of his T-shirt.

"Thanks Issac, I'd love to sit for a bit," She briskly entered and sat herself on one of the chairs. Issac was seemingly searching for the notes through his bag. With her eyes not on her at the moment, she couldn't help but goggle at him. Something seemed... off about him. She remembered him being pretty hot and fit, but he seemed to be more handsome the more she looked. Then she finally noticed what had changed.

"Hey, you got a haircut, nice! It looks amazing on you!" She did her best to get his attention.

"Oh, thanks! Just decided it was time for a bit of change." He replied, giving her a slight grin a she looked back to her. His hair did look pretty good now short then it did longer, but she came to realize that wasn't the sole reason for her new found affection for him. It couldn't be, it was just a haircut. She could feel herself getting hot and flustered, with a sudden need greater then anything she had ever felt towards Issac. She took off her jacket all the way, flexing her top a bit as she did. Her top and bra were feeling tighter by the second.

God, I must be breathing too much now, its stretching out my bra too much

She could see Issac occasionally catching glances over at her, while he moved from searching his bag to checking a stack of papers on the kitchen counter.

"Would you like some Key Lime pie Lynn? We still have a slice or 2 I think." He asked, gesturing to the fridge. As he said it, a wave of arousal rushed over Lynn before she could give a response.

"Ahhah-Iiii, am, fine, thanks Issac" Her breath was noticeably shaky now as she tried to recover.

"Not a Lime fan?" Issac asked, peering over his shoulder as he was looking in some cabinets, for whatever reason. Lynn felt another wave of warm arousal rush from her head down to her nether regions. She immediately tensed her thighs together and bit her lip to resist making an unmistakably lewd moan.

"mmm hmm" she managed to murmur, shaking her head no. She was loosing control, she felt the arousal and need towards Issac causing her to shake and tremble.

On top of that, Lynn could feel the fabric of her bra stretching along her back, and could hear the it straining underneath her top. She felt her breasts pressing against the inside of her bra, her nipples being firmly pressed against the inside of her bra. It felt good, but that didn't help her arousal and already confused state. Her boobs were poking out way more then usual, she had to get her bra off before it snapped.

"Hey, can I use your restroom for a bit? Just need to... relieve myself." She turned her attention off her chest back to Issac, and she quickly felt a wave of arousal come back over her again as she got a look at his rippling muscles. He gave her an inquisitive look, his eyes checking her out up and down.

"Sure, go ahead, do whatever you gotta do. I'm sure I'll find my notes somewhere in my room." She went into the bathroom that was right off of the entrance to the room. She quickly went to unbuckle the back of the bra, and it immediately disconnected from her back. She expected them to fall to the floor, but it was still held tight against her top. She struggled to take it off with her tank-top still on, but to no avail. She eventually just pulled her whole top up and over her head. The relief was immediate, and she immediately got to catch her breath.

With the strain on her boobs now subsiding, she began to focus on other parts of her body as she began to calm herself. Now being in the bathroom and away from Issac, her need and arousal for him seemed to fade. It was like a pressure that was slowly being applied inside of her, deep inside her pussy to make her more and more needy, that had suddenly been put at ease. She could feel a moistness in her pussy that, while not getting worse at the moment, was definitely not going away anytime soon. She had to lean on the sink to catch balance a bit, and then realized how low her tits were hanging.

Lynn looked up to the mirror and saw her boobs were noticeably bigger, almost double the size they were before. Her's weren't exactly big in the first place, but she knew very well that they were never like this, even on her periods which did cause them to swell a bit. But these were way bigger, and as she stared at herself in the mirror in shock, she could see them growing bit by bit, growing out with a small jiggle every second or so. She reached up to feel her chest and it sent a tingle from her chest up her spine. It felt...

Amazing,

she couldn't help herself from groping. It was like she was touching skin that had recently healed from a sunburn; but it didn't hurt, instead she felt pleasure. The new nerve endings that filled her larger breasts were fresh and sensitive. She tried to rack her mind as to how it was happening, or why it felt so good to touch, but she couldn't explain it. It was even better than if she was fingering herself, which she got reminded of as her pussy started to drip again. She instinctually let out a moan, and quickly went to cover her mouth. She didn't want Issac to hear, and think of her as a total slut, but it felt too good to want to stop. Just a few more minutes...

Issac

Issac definitely heard Lynn's moan from his room, but he didn't need to hear that to know that she was enjoying herself. He had pulled up the Master PC 3D viewer and was watching the whole thing. It was fun teasing her and stalling for time to get a glimpse at her transformation in real time. She was obviously struggling with her tight top and sudden arousal when he had brought up Key "lime" Pie, so he was glad that trigger was working. He didn't expect her to want to excuse herself to alleviate her growing chest however, but it was a kink he had to iron out as he learned how best to utilize his program. The full transformation had run its course now, with her new tits exactly how the program had predicted. It was so hot watching her give in and touch her new assets, he couldn't help but take his cock out and begin to stroke. It felt so amazing, feeling his new cock pulse with the need to fuck her perfect new tits. He decided it was time to speed things up a bit to make Lynn ready for some fun.

Issac went into her settings again and amplified the sensitivity of her breasts by 40%. He also decided to make them grow some more, up to an 38E cup. He then went to the Kinks setting and added Exhibitionist, so she wouldn't be afraid to show off her new assets in the future. He knew she'd enjoy that, but just to be sure, he went into her mental settings and inputted

Loves big tits, especially her own. Enjoys playing with and having her tits played with

. That'll ensure she doesn't have any regrets about her new tits. He then input

Is not afraid about being nude or being sexual around Issac, and vice versa

. He had a plan in mind. He also decided to up her minimal horniness to 20% at all times, and adjusted her attitude to be more slutty, and slightly submissive. He still wanted to be able to take control if he needed to. He scrolled through Lynn's options and found the Partners section. It seemed like besides her recent ex, she had 2 lovers before him. Issac added himself to the list of partners as

Friend with benefits

. This, along with her casual nudity with him and constant horny buzz, he should be able to get a nice tit fuck whenever he saw fit. He checked the last boxes,

Modify History

and

Subject is Unaware

and was about to hit finalize when he remembered one last thing to add.

Loves Key Lime Pie, which acts as an aphrodisiac for her and her alone

.

There, that'll do it

Issac smirked to himself and hit

Finalize

. He then got up and headed to the bathroom to meet his new fuck buddy.

Lynn

Meanwhile Lynn unbuckled her jeans and reached her hand down to sate her need. She began to rub her clit, and her legs immediately buckled a bit. A warm pulse again washed over her like the one in the hallway, and she had to grab the counter in order to not fall to the floor in ecstasy. She moved to sit on the toilet seat, and was lost in a pleasurable need to grope herself. She realized her moans were getting louder and louder, but she didn't care if Issac heard, it felt too good to stop. Her hands ravenously groped at her massive tits. They were so fucking perfect, and she loved herself for them. She loved showing them off, and making people fantasize about what they look like under her clothes.

As she pleasured herself, she saw the door open and Issac was there, with his pants down and cock out.

"Well well well, someone's having all the fun without me." He said, stroking his cock. Lynn had seen it dozens of times, and it always felt so good between her tits. She had a sudden realization; why was she hiding in the bathroom? She shouldn't be afraid to show off her tits to Issac? She must have wanted to warm up some... fuck she couldn't remember.

"Sorry, ohh fuck, don't know what I was thinking" She said, fighting her own moans to complete a single sentence. "It's just been a long day and, jesus, couldn't wait for you to find your stupid notes so I could, oh FUCK, fuck you as payment." Her whole body felt like it was on fire the more she looked to Issac. He had taken such good care of her since she dumped her ex. He was too controlling, and was more of an ass man then a tits man, and never fucked her tits. But when she started needing to visit Issac for homework, it gave her a great excuse to offer her bountiful chest as thanks.

"Is that our arrangement?" He mocked coyly from the doorway, "I think it's safe to say we don't need a reason to at this point." He said, walking over to her. Lynn stayed seated as he came over. He grabbed her breast and began to squeeze it just how she loved it. Her head immediately shot back in ecstasy.

"God, your tits are so beautiful Lynn." Issac's praise fell on deaf ears, as Lynn was consumed by a wave of pleasure and ecstasy to the feeling of someone groping her tits. It was greater than anything she had felt before, she had to grip the seat to keep herself from sliding off.

Issac took his hands off her tits after a light slap which almost sent Lynn over the edge to orgasm. He moved down to her legs and stripped her tight jeans off her, which were down by her ankles from all her flailing and squirming. There was a noticeable wet patch on her panties, something that was a often occurrence nowadays. He ran his hand along her underwear and let her cotton panties soak up her pussy's wetness. She was soaking them and his strong fingers pressed against her slit felt great.

"Such a needy girl huh" Issac said, his fingers getting moist even through her panties. "Come on, lets go to the bedroom so we can take care of that." He gave her nipples a quick pinch before he left the bathroom, and Lynn gave a light shriek.

"AAHHHH, yes Sir..." Lynn took a moment to catch her breath, before getting up to follow him. She hadn't come yet, and Issac was being perfect about keeping her right on the edge. As she went to the bedroom, she stripped off her panties and felt for herself how soaked and needy she was. She couldn't decide whether she wanted Issac in her pussy or between her tits...

Issac

Issac was sat on the edge of his bed, awaiting Lynn to reenter the room. She came in with her panties off, and her tits bouncing perfectly as she walked in. Her grown assets were even better, and turned her into the spitting image of a pornstar. She moved up to Issac, and kissed him as she laid on top of him, pushing him down onto the bed.

"So, which do you wanna fuck first, Sir?" she whispered into his ear as she began to grind onto him. "Tits or Pussy?" Issac could feel her pussy dripping onto his leg, with his hard cock rubbing against her stomach. He wanted to just grab her firm ass, and slide her right onto his needy member, but he had made all these changes to her for a reason.

"I think you know", he said, as he groped her tits again. Instantly, any sense of control and power she was enforcing over him instantly melted.

"Fuckkk, Yes Sir" Lynn slid off the side of the bed on her knees so she could properly pleasure him on the lifted bed. He spread his legs and finally let her put her tits around his cock. It instantly felt amazing, her soft cushiony tits felt so warm as they consumed his now leaking member. The way his cock's head was continuously being stroked by the top of her tits as she bounced them up and down felt so amazing. His cock slipped perfectly in the groove between her tits, becoming more and more slick as he leaked bits of precum between her tits.

It was clear that Lynn was also enjoying it more then usual. She bounced up and down, groping her own tits so they were tight against his cock. She began to settle into a rhythm, each bounce provoking a moan and heavy breath from her.

"Fuckk I love giving you tit fucks! Your cock is so fucking gooood!" She began speeding up, leaning her body against the bed for more support. Issac gave a hand and wrapped his legs around her and pulled her closer.

Lynn took her tits off for a moment to take his cock in her mouth, licking up a big glob of precum freshly leaking out, and leaving a hefty amount of wet drool behind. After adding an extra bit of spit, she resumed bouncing her tits on her cock, and with the new wetness covering his cock, she was able to bounce her tits even better. She changed her hands to have an even tighter grip to completely obscure his dick now, and began to bounce even more. She bounced as if she was riding a cock, and it clearly was driving her insane with pleasure. She kept this rhythm up so consistently, Issac thought she would go forever. Thanks to the gifts he gave himself, he was able to control when he came and was simply enjoying how amazing her tits felt. Eventually, her pace slowed a bit, being more careful and delicate. He could tell from the blissful daze in her eyes that she was on the verge of cumming. He had mostly let her fully enjoy herself, just using her cock as a mean to fuck her own tits, but now he began to move his hips with her rhythm.

"Oh fuck, oh fuck, oh FUCK, I'm about to-AHHhhhh" Her pleads was cut short as Issac groped her tits and began to thrust rapidly between her cleavage. Held in place by his legs her body tensed up and he could feel the tremors of an orgasm rippling through her as she let out a lustful scream. At the same time, Issac willed himself to cum, covering Lynn's tits with a healthy load of cum after watching and edging to her for roughly a half hour. This only acted as a bit of over stim to the already pleasure broken Lynn. Her eyes rolled back and she gripped the bed tighter as each sloppy thrust into her tits melted her mind bit by bit.

After about a minute of a cum covered titfucking, her body finally gave out, and went limp against the bed, her head resting against Issac's thigh. She hadn't passed out, but her muscles were simply unable to tense any longer. Issac took a moment to admire the cum broken Lynn, with her covered breasts shaking as she caught her breath. He reached under her arms and pulled her up onto the bed, and got her in a more comfortable position than the floor. Both out of breath, sweaty, and horny as fuck, they began to spoon. Lynn didn't object, she barely seemed to move on her own, even though she was still breathing deeply and occasionally cursing under her breath.

"Lynnnn, you still there?" Issac lightly ran his hands over her tits to wake her up. He could tell she was still super sensitive, as her back arched a bit from him even running his nails along her chest.

"Gnnggghhhh yesssss, I am.... Fucking... holy shit..." She was clearly still a bit dazed, but he was at least happy she was aware at least. "That was... so amazing. That felt like it was the first time I had ever truly orgasmed... The last titfuck was nothing like that, holy shit..."

Issac reckoned that the Master Pc had implanted some vague memories of them being fuck buddies, but none that accounted for her new hyper sensitive tits. "Yeah, it felt amazing for me too" Issac groped her a bit harder with that and kissed her neck as she reflexively shuddered a let out a small moan. "I'd be more then glad to do that again, but you seemed tuckered out."

"Maybe not today..., but fuck we gotta do that again..." Lynn sighed, and looked over to Issac's bedside alarm. It had been 45 min since her brief pickup of the notes, and she was going to be late back to her dorm.
