Checking for Lumps
by Pan
Chapter 1
“It’s important,” my brother said, standing in my doorway.
I sighed and looked up from the computer screen. My brother is always coming into my room. He was ten years older than me and left home for college when I was only eight, so we’d never spent much time together. Just family holidays and stuff like that.
Now, ten years later, he was a fully-qualified doctor. And, honestly, a bit of a know-it-all about it.
“I know,” I sighed. “But I’m only eighteen. It’s not like these”—I gestured to my boobs—“are about to explode tomorrow.”
He shook his head. “You never know.”
I rolled my eyes. When Alex got a bee in his bonnet, it was impossible to talk him down. “Fine,” I said, turning my attention away from him. “I’ll check in the shower tomorrow.”
I thought that would be it; he’d gotten what he wanted. He’d won. But when I looked up a few moments later, he was still there, standing in my doorway.
“Now,” he said, and I raised one eyebrow. He couldn’t be serious.
But as I looked at him, I realized he was. “Alex...” I began, but he held up one hand.
“Tammy,” he replied sternly. “I’m a doctor.“
My eyes widened. Fuck. I mean, I’d known he was a doctor, but...I dunno, the way he said it. I suddenly knew that I had to do what he said.
I had to do what he said.
Without another word of complaint, I stood from my chair, and awkwardly moved my hands up to my shirt-covered breasts.
“Do you mind...turning around?” I asked nervously, but my brother shook his head.
“I should watch,” he said firmly. “Make sure you’re doing it right.”
Something about that didn’t sit right, but...well, who was I to argue?
He was a doctor.
So while my brother watched, a strange expression on his face, I checked my breasts for lumps. First my left tit, then my right. After several minute of poking and prodding, I turned to my brother expectantly.
I don’t know what reaction I expected—a “well done, you nailed it”, I suppose—but I was met with a small shake of his head.
“W-what?” I asked, suddenly embarrassed.
“Well, first of all, are you wearing a bra?”
I nodded.
“So you’re checking through two layers. After just telling me you were going to check tomorrow in the shower. Nude, I assume.“
“I, uh...”
He continued to stare at me, and I fell silent.
Yeah. I didn’t really have an excuse. I just hadn’t wanted to...y’know, strip off in front of my brother. Because he was my brother.
But, more importantly, he was a doctor. And so I dismissed my dumb hang-ups, and slowly removed my t-shirt before tossing it onto my bed.
Standing in front of my brother wearing nothing but a bra felt slightly awkward, but I tried to that he was a medical professional—and related to me—and that this was as normal as stripping off in front of a girlfriend, or my Mom. With that in mind, I unhooked my bra, and shrugged it off, letting it fall to the floor.
Alex’s attention turned straight to my bare tits. It was nothing but medical curiosity, I reminded myself—he wasn’t looking at them as a man, but as a man of medicine. And so I straightened my back, pushing my tits out slightly as I did.
They’ve gotten more than their fair share of attention over the past few years; as soon as I hit puberty, they started growing like crazy, and by the time I was seventeen they were large enough to need special . So I bought a couple of bras specifically designed to keep my big boobs from bouncing, and I wore them pretty religiously. This wasn’t the first time I’d been topless in front of a man, but it was definitely the first time I’d shown them to someone who I wasn’t...interested in.
But this wasn’t foreplay. It was a medical thing.
As I stood there, Alex just didn’t stop staring. If he hadn’t been my brother—and a doctor—I would’ve mistaken the look in his eyes as lust, like he was checking me out. He kept moving his gaze from my face all the way down to my chest, and back up again. It was incredibly uncomfortable, but I didn’t say anything. I’d already embarrassed myself in front of him once, and I didn’t want to repeat the experience.
As he stared, I blushed furiously: I could feel my nipples hardening, and I was acutely aware of how pink they were. How soft and round my breasts were. How much men wanted them. It was a strange thought to have about my own tits, but as Alex stared at them, I couldn’t help it.
I had fantastic boobs. I didn’t know anyone with bigger breasts than me, outside of extreme fetish porn on the internet. Every guy who saw them stopped and stared, and apparently my brother was no exception.
No wonder he was so concerned about finding a lump. Getting a double mastectomy when you had a bosom like mine would basically be a crime against nature.
And so, as my brother watched, I carefully checked for lumps. One by one, I ran my fingers over each breast, feeling for any irregularities or bumps.
The whole time, he just stared.
“Nothing,” I confirmed, finally.
I thought that would end it, but, no.
“How can you be sure?” he asked, and I honestly wasn’t sure how to answer.
“Because I...didn’t find anything?”
“But how do you know?” he repeated, and I finally understood what he meant.
My understanding had always been that you’d know if you found a lump. That it’d be like finding a piece of gristle in your soup, instantly recognizable as something that wasn’t supposed to be there.
But what did I know? I wasn’t a doctor.
Fortunately, I had one standing right in front of me.
“Would you like to check?” I asked my brother, blushing furiously. God, what if he got the wrong idea?
Fortunately, Alex is a professional. If he wasn’t, I could easily have mistaken the look that appeared on his face as one of lust, instead of what I knew it to be: simple doctorly enthusiasm.
Right?
He nodded. “Yes,” he replied. “But only as a special favor. Y’know, cos you’re my sister.”
“I appreciate it,” I said, still beet-red. All of a sudden, I felt self-conscious about my own thoughts. Like, why would I have even worried he would think my request was anything other than asking for his medical opinion?
He was my brother. And he was a doctor.
I tried to breathe normally as brother reached forward slowly, cautiously. Professionally. I felt his warm, calloused fingers brush against my skin, and I shuddered slightly at the feeling.
It had been a while since I’d had a man touch my breasts. And of course, this was the first time that person had been my brother.
I looked up at him, trying to make eye . His eyes were locked on mine, but his focus was entirely on my bare tits. For almost ten minutes he slowly checked them, pressing gently here, prodding there. I squirmed as he tweaked my nipples, tried to ignore his smile as they hardened in his hands.
I felt strangely comfortable having him examine me. After all, he was a doctor. A professional.
When he finished, I took a deep breath. “Anything?”
“I can’t be sure,” he said, shaking his head. “There’s special equipment back at the office that would let me check more thoroughly…but since we’re so far from there, I might have to use my mouth.”
My eyebrows shot up. “Your mouth?“
It didn’t make any sense. I’d never heard of such a thing. Why would he need to use his mouth on my breasts? That was so invasive—It wasn’t like anything I’d seen before.
“That’s the best way,” he explained, reassuringly. “It’s the only way I can be sure.”
“What are you talking about?”
“It’s called ‘oral palpation’, Tammy,” he explained. “It’s used to detect hard-to-find tumors and other abnormalities in patients. Frankly, it’s just as good as the equipment, if not better.”
“I don’t know if I’m comfortable with this...” I said, squirming slightly, and my brother looked at me sternly.
“I’m a doctor,” he reminded me, and my blush returned.
Right. Duh. Why did I keep forgetting that? Of course he wasn’t going to try to take advantage of me—I was his sister, and he was a professional. A doctor.
With a sigh, I nodded. “Whatever you’ve got to do, doc.”
My brother licked his lips as he leaned in and began exploring my chest with his tongue. He ran it up and down between my breasts, circling my nipples. Each time he did, I felt a tingle run through my body as the sensitive nerves in my breasts reacted to his touch.
I tried to remind myself that this was a simple medical procedure, that he was my brother, a doctor, but...well, apparently bodies don’t really work that way. When someone starts licking your breasts, even if they’re a doctor—even if they’re your brother!—you’re going to get turned on. And so as Alex took one nipple into his mouth and gently sucked, I felt myself getting wet.
I closed my eyes, trying to ignore what was happening. I didn’t want Alex to think that I was enjoying this. I didn’t want him to think that I was some kind of pervert. Here he was doing me a favor, and I was reacting like this was...I dunno, foreplay.
Fuck. Was there any way I could tell him to stop without making him suspicious?
I didn’t want to it that I liked it. I didn’t want to it that my brother’s tongue felt good on my breasts.
But at the same time, I couldn’t deny what was happening. How my body was reacting.
I opened my eyes. Alex’s eyes were locked on mine, and I couldn’t look away. I was trapped, unable to look anywhere except into his blue eyes. As I watched, he switched his attention from my right boob to my left, then back again. With each lick, each suck, I felt myself becoming more and more aroused.
And with every moment, I felt more and more exposed in front of my brother.
I couldn’t look away. But I also couldn’t bring myself to ask him to stop. This was a medical procedure, after all. My doctor needed to see exactly what was going on with my breasts. He needed to feel them, lick them...it was important to check for tumors.
It wasn’t his fault that my girls were so sensitive.
Finally, after what felt like half an hour, Alex was done. My entire chest was coated with his saliva, and I knew I was breathing heavily. I wanted nothing more than for him to leave so that I could touch myself, so that I could relieve the pressure building inside me, but he just stood there, waiting for my reaction.
“Are you okay?” he asked, and I nodded, not trusting myself to speak. “You seem...”
He trailed off, and my blush got impossibly deeper. What? Aroused? Turned on, by my own brother licking my boobs? That morning, I wouldn’t have thought that it was possible to be turned on by Alex. That he could make my pussy start dripping with need. That I’d find myself craving more of his touch, of his tongue…
I would’ve been wrong.
I felt as though I’d been caught masturbating. I was so ashamed.
“...unwell,” he finished, lips pursed.
My eyes widened. Oh, thank god. He’d mistaken my arousal for sickness! I was so relieved—he had no idea how much I’d enjoyed his mouth on my tits. He’d offered me the perfect excuse.
“I think I might be,” I finally stammered, and Alex sighed.
“In that case, I should give you a full checkup. Take your clothes off and lie down.”
It felt like every drop of blood left my body. I was suddenly filled with terror—I was going to have to strip naked in front of my brother. As soon as I took my panties off, he’d know. He’d know how wet I was. How wet he’d made me.
But Alex didn’t seem to notice my hesitation. His eyes flicked down to my chest, and then back up to my face. “I didn’t find anything,” he added. “But it never hurts to be sure.”
“I t-think I’m okay,” I managed, finally. “I’m fine. Don’t worry about it”
Alex shook his head. “We should have you checked out just to be safe. Just take your clothes off and lay down on your bed.”
Still, I hesitated. And so my brother looked me in the eyes and said three simple words:
“I’m a doctor.”
