Natalie's Birth Control Diary

"Alright, Natalie. Please remove your top."

There was something about Dr Lewis' gaze that just made Natalie instantly shy. Yes, he was handsome, and unlike the doctors back home, he was young — forty, tops. But that wasn't it. What always made her incredibly self-conscious was the way he spoke to her with real authority.

It felt like a command, and sometimes she swore she was being hypnotized.

Natalie did as the doctor asked. This wouldn't have been the first time he had inspected her body, but given how few people ever saw her topless, it made her feel shy nonetheless.

She was wearing a zip-up hoodie with a tank top underneath, no bra — with Natalie's small, perky boobs on a petite frame of five foot two, there never really was a need to do that.

With Dr Lewis observing neutrally, she had to look away, because there was something about his gaze that just turned her on… and she didn't want him to know. So she looked to the floor, muttered something in the affirmative as she obeyed, and unzipped her hoodie, placing it to the seat next to her, along with her tank top, which she pretty much shrugged off.

"Stand up, please."

She stood, first facing forward and then giving him a side-profile angle. He came forward, placing his gloved hands on her skin, focusing on her abdomen.

That was good. She always felt shy about being 23 years old and having no boobs at all. Like, seriously. No wonder all my exes called me barely legal.

"You mentioned bloating?" Dr Lewis said, applying a little pressure on her tummy.

"Yeah," Natalie said, trying to avoid blushing again. "I think it's the…"

"It is," Dr Lewis nodded. "The birth control. Fairly sure. I've seen this before. I'm sorry about that. You've been on this pill for what, three months?"

"Hasn't really done me any good," Natalie said, trying to muster a smile. "Not really that active, you know?"

"You don't have to justify your sexual activity to me, Natalie," the doctor answered pleasantly. "What other side effects have you been experiencing?"

"Headaches. Mood swings. I don't know, a few side effects, I guess. I've also been skipping lately, but when I get back on it the effects are worse. So I was thinking about seeing if I could stop full-time," Natalie said, frowning.

Dr Lewis paused. "I wouldn't recommend stopping. You might want to switch to something else. I'm going to examine the rest of your torso, okay?"

When he touched boobs she couldn't help it: she blushed. She might have even made a sound. That made her blush even more. The doctor said nothing. That was nice of him.

"This is a textbook case of a hormonal reaction, nothing more. You started taking your current pill before you moved here to be a graduate student, is that right? That's what it says in your file. Anyway, I have a solution."

Natalie gulped. "Okay…"

"Rather than risk going off the pill and messing with your hormones even more, it would be gentler to just switch to a different, less intrusive pill. You don't have to worry about cost, it's an experimental drug — but the studies have been very positive."

"Is there anything bad about it?" Natalie considered. She had a knee-jerk reaction to the idea of being a guinea pig, but now that she thought about it, wasn't this what she was already doing?

"Not really. I can make sure you get this on your insurance plan for free, at least for the first year, but there's a condition. You have to write a diary detailing any side effects."

She paused and finally looked up at Dr Lewis. "I think I can do that."

"Excellent. Give me a second, I'll get you a month's supply. You just keep taking them like you have been. Try not to skip, though."

"Can I really just start going on this new pill immediately?" Natalie asked. "I just took the old one yesterday."

"It's safe — there shouldn't be any harmful effects. But if there are, please, don't forget to detail them in your diary."

Dr Lewis handed her four blister packs of pills, each numbered. "It's important you take them in the proper sequence. This will help counteract the hormones for your benefit."

"If you say so, doc. Uh, so they're free?" Natalie asked, looking down at the pills. They were a pale, pastel pink, much like the previous ones she had been taking, except the last ones were almost barrel-shaped whereas these ones were perfectly circular.

The discreet bottle said only the name:

Titgrofinide, 50mg.

Day 1 (Friday)

Dr Lewis gave me the new pills. I took them as soon as I got home. Didn't feel funny.

That night I woke up hot and sweaty, and I think I had a really intense dream, but I can't really remember what it was.

Day 2 (Saturday)

Not feeling hot and sweaty anymore.

I don't know if it was because I had a gym morning that really kicked my butt, but my body feels sore. My chest especially. Not my heart or anything, nothing so serious.

Just my boobs.

Day 3 (Sunday)

OK, so I don't know what I should even be logging in this diary but since it's going to be seen by a doctor I'll talk about everything to do with my body since it might be related to my journey with Titgrofinide. Ugh, "my journey with…", I sound so lame.

My nipples feel a lot more… noticeable. I don't wear a bra out most days but I'm probably going to have to now, because guys are staring. And those girls are rock-hard all day.

Day 5 (Tuesday)

Either my bras are all shrinking or my boobs are getting big. Like, swelling big. They feel really tender. My friend Amy playfully cupped them today and was like, "Nat\! You have boobs\!"

Day 6 (Wednesday)

It's not tenderness\! It's weight. My chest feels funny because my boobs are full and big. Amy's taking me bra-shopping and I'm a small C now. This is so weird. I spent half an hour in the dressing room looking at my boobs.

Day 8 (Friday)

Went out with the girls and I've never gotten attention like this before. Oh my God. Guys kept coming over, buying me drinks. Usually that's reserved for Amy, our resident hottie, or someone like Lisa or Sydney. Tonight they were all over me.

I was wearing a loose, low-cut dress because the change to my boobs have made almost every top I have look extra slutty, but the problem was I had to practically hold my dress together because I was sure my boobs would fall out of my dress. I mean, the guys would love that…

While dancing I think I actually felt my boobs grow. Maybe this is just me feeling aroused or something (is it okay to write 'horny' in a diary that I suppose a doctor's going to see? This feels weird.)

Weird in a great way.

Amy was so jealous.

Day 10 (Sunday)

So… confession. I've been taking these pills every day like a good girl and I thought to myself, given how I've definitely felt an increase in my libido (still not writing 'horny' in this diary, sorry) I figured since I am on birth control I might as well have a bit of fun.

A guy from my literature class was at the bar, we started flirting, he took me to the bathroom and started… you know. He was so into me. I'm not even a sex on the first date sort of girl, so I was feeling so shy.

It felt so slutty\!

And my boobs were so sensitive, he kept praising how big they are, kept rubbing them, made me ride him in the bathroom while he buried his head in between my boobs.

Honestly, they're full-on bimbo tits now. I'm just going to use 'tits' from now on.

Right before I came he had this awe-struck voice, asking me, "Are they getting bigger in my hands? Seriously. Natalie, your tits are huge."

I came really, really hard.

Day 11 (Monday)

Spent all day wondering if I should rewrite my diary entry for yesterday, decided I shouldn't.

Day 13 (Wednesday)

I think the center of my bodily sexual pleasure is my boobs now. It feels like my nipples radiate all my arousal. (And I am horny all the time. There. I said it.)

Booty-called that guy from the other night over and we were at it all night long. I could tell he liked it best when I was on my hands and knees, because he starts moaning so much when he's fucking me deep while fondling my tits.

By the way, I'm definitely not a C-cup anymore. I can't fit anything I bought a few days ago.

Day 20 (Wednesday)

Too horny. Too damn horny. I wake up, I take a pill, I lie in bed, I touch myself. Sometimes I text guys to come over. Sometimes they do. If they don't it's okay too, I can get myself off.

All I need to do is touch my tits. They're so big\! I'm so happy I switched pills.

Day 21 (Thursday)

At the mall again, trying to buy some new clothes since nothing fits me again. Why can't I just go around topless? I should start going around topless.

I used to look so bloated on the old pill, now my body's curvy. "Bimbo curves," that's what the guy from this morning said. He worked at the mall. I was in the dressing room, trying out a little black dress when I decided I needed his help. You know the drill. His hands, my tits; his cock, inside me.

Can't return the dress, it's got a lot of stains on it.

Day 23 (Saturday)

I have five days' of pills left. Titgrofinide has changed my life. The thought of going without it for even a day makes me so mad. Horny-mad. Ugh. I don't think I even have emotions anymore, unless it's horny-something.

Dr Lewis wanted to schedule me for a follow-up appointment this coming Friday, but I did the math in my head — big-titted bimbos can do math, believe it or not — and realized that would leave me without the pill for one day so I put on my neediest, sluttiest baby voice and told him it had to be Wednesday or Thursday.

I think he got the message.

Day 25 (Monday)

Started the week right with one new guy in the morning, one in the afternoon, one in the evening, and one just before midnight. Two of them were virgins. On campus I sometimes try to cover my huge tits with books and binders and files but all that does is get guys following me around offering to help me carry my stuff.

I'm happy to trade one favor for another.

The highlight of the day was definitely seeing Professor Armiger for a one-on-one session where he explained to me the difference between the Italian and Flemish Renaissances, with his cock down my throat and his hands practically milking my tits…

Day 27 (Wednesday)

Mom and Dad tried to FaceTime me after dinner and catch up for our monthly call, but they did not recognize me at all. "Why are you wearing all this makeup? And why are you wearing only a towel? Honey, can you please cover up?"

I tried to explain that I was contributing a great deal of valuable information to science, but as hard as I tried to behave, my voice is now at a permanent porn baby doll tone and everything I say sounds like dirty talk and heavy moaning.

They were very confused.

They'll come to terms with it. I know I have\!

Day 28 (Thursday)

So much anxiety. Got to walk to Dr Lewis's clinic now. Oh yeah, he's supposed to read this, isn't he?

\\\*

"Whoa, Natalie, I didn't even ask you to take your top off yet," Dr Lewis said, smiling… no, smirking.

He had a very self-satisfied look on his face. This was a surprise to Natalie, because all men generally only gave her stunned looks of pure awe, dressed or undressed.

It was almost as if he wanted this.

"Well, it's more comfortable this way, Daddy," Natalie said, pouting.

She only caught the accidental use of that word after she said it. Oh, now she blushed. Had she always been this shy? It almost felt like a lifetime ago that she wouldn't even take her top off for a doctor.

Oh right, that's the word I was looking for. "Doctor."

Still sounded like a moan.

Dr Lewis paused to watch her. Usually he'd be on her by now, inspecting away, making very distant, medical observations about her body. Instead it was almost as if he was resisting the urge to do so.

"Well," he said, after a time, crossing his arms in front of him, "I think you're looking great. Health, I mean. Are you happy with your new prescription birth control?"

"Doctor, I love it. Love it. It's changed my life."

Dr Lewis smiled-smirked again. Something about that authoritative look made Natalie instantly wet. Once upon a time she was sure she'd just be shy, but now she embraced her true self.

"Did you do as I say and document any side-effects you've experienced on Titgrofinide?"

"I always do what I'm told," Natalie moaned. She dug into her handbag. Some guy bought it for her the other night, she can't remember why it was — probably because she let him fuck her, fondling her tits the whole time like his hands were stuck to her by glue. "Here you go."

"Thank you," Dr Lewis said, voice full of that impressively unaroused courtesy. "By the way, by my count, you're pushing into H-cup territory. We can reduce the dosage on next month's supply if you'd like."

Natalie laughed. "They're not even big enough for me, Doctor."

"Mmm," Dr Lewis said. "Then maintaining the present prescription will help you achieve your intended size."

"I took them all in sequence, just like you told me," Natalie said, sitting back, her hands immediately weighing her breasts up. She couldn't even come close to cupping them full. She was even wondering how her back was capable of supporting her huge tits now.

The doctor smirked again. "Sounds to me like you really want to stay on Titgrofinide."

"I'll do anything…" Natalie said, sitting up straight.

Dr Lewis said nothing. All he did was sit back in his chair, uncrossing his arms, watching her carefully.

It was that look again. But this time it wasn't so much authority as it was him daring her to prove what sort of a good girl she could be for more of these pills.

And all Natalie had to do was climb over his desk and straddle him.

She would do anything to have bigger tits. She was ready to look perfect.

And in the back of her head, she thought that it was a really great thing that she was on a really effective course of birth control, because now she really needed not to get pregnant — guys couldn't get enough of her, and she couldn't get enough of them.
