Checking for Lumps
by Pan
Chapter 2
I didn’t even stripping. But all of a sudden I was naked, laying on my bed, the smell of my soaking wet pussy filling the room as my brother ‘inspected’ me.
He took his time, looking over every inch of my naked body. I kept my pubic hair trimmed short, which seemed to catch his attention. It felt like he spent longer studying my pussy than the rest of me put together.
As I watched, I saw his nostrils flare slightly. He was sniffing, smelling me. Smelling my arousal. But had he put it together? Had he realized what had turned me on so much?
“You’re unusually wet,” he said, wrinkling his nose, and I could do nothing but nod. “That could be a sign of an impending illness. Do you mind if I...”
Before I could say anything, his hand was on my leg, rubbing softly up and down between my thighs. I gasped, surprised. I’d imagined he’d start the examination elsewhere, but my brother’s hands were already exploring my pussy.
His fingers slipped inside of me, sliding in and out of my wetness. I bit my lip as he touched me, watching him closely. There was no trace of lust or lechery in his blue eyes. He just seemed concerned, curious.
He was a doctor, after all.
“How does that feel?” he asked, his voice low.
I didn’t know what to say, so I just bit my lip as he continued to stroke me. His fingers moved in and out at a rapid pace, exploring my tunnel, making sure that I was healthy. But his touch felt so good, and I felt myself getting closer and closer to cumming.
This wasn’t right. Right? I’d had many doctor’s appointments in my life, but none of them had...brought me to orgasm. Even just thinking the words was enough to confirm how very wrong this was.
This was wrong. My brother shouldn’t be touching me. He definitely shouldn’t have his fingers between my legs, sliding them in and out like a cock. I needed to sit up. I needed to say something. I needed to resist!
“Don’t worry,” he said, before I could get the words out. “This is all perfectly normal. I’m a doctor.”
I lay back, relieved. Of course. What had I been thinking? He was a medical professional; it wasn’t my job to tell him what to do.
It wasn’t my job to say no.
“Just relax,” he said. “Let me take care of you.”
He spread my legs apart with his other hand, continuing to slowly saw in and out of my pussy. Slowly, I relaxed. I felt his fingers slide deeper into me, slipping past my tight walls, pressing against my g-spot. I moaned as he touched me, and he smiled.
“Does that feel good?” he whispered.
“Mmmhmm,” I mumbled, too embarrassed to say anything else. The sensations he was causing inside of me were intense.
He slid a third finger inside of me, and I groaned loudly. “How about that? I’m just checking your...capacity.”
“Oh fuck,” I gasped. “Yes...yes...right there!”
“Good girl,” he murmured, and I whimpered with pleasure at his words. “I mean, good patient. You’re such a good patient.”
His other hand returned to my tits and resumed inspecting them, checking for lumps. He tweaked and pulled at my nipples as he examined my chest and pussy, and I groaned, leaning back and closing my eyes. He was driving me insane.
I could barely think straight. All I could do was moan, plead, and whimper as my brother pushed his fingers deeper, stretching me open and exploring every inch of my insides with his probing digits.
I didn’t want to cum. I couldn’t believe this was happening, that my brother—my doctor!—was fingering me like this. But at the same time, I knew I had to trust him.
I had to.
He was a doctor.
“Right there,” I gasped, and my brother smiled. He stroked me faster and I cried out as I came, my body shaking as I spasmed around his fingers. But even when I was done, he didn’t slow down, and soon I felt a second orgasm building.
“Oh, fuck!”
I’d never been multiorgasmic. Perhaps that’s what Alex was checking for? That didn’t sound right, but as I felt another wave of pleasure crashing over me, I couldn’t think. Didn’t want to think.
Just wanted to cum...
His thumb rubbed against my clit for the first time, and I shuddered. I threw my head back and screamed, clutching onto my sheets as wave after wave of bliss washed over me. I couldn’t stop myself from moaning, from screaming, even as my orgasm faded and my breathing slowed.
And then I heard my brother murmur, “Interesting.”
I looked up at him, and his smile grew wider still. “I think I’m getting closer to working out what’s wrong with you.”
In that moment, it didn’t feel like anything was wrong with me. I mean, except the fact that I’d just been fingered to a double orgasm by my brother. But honestly, even that wasn’t worrying me. I felt like I was nothing but a puddle of bliss.
I didn’t want to let on how much I’d enjoyed that, however, so I forced my mouth into a frown. “What do you mean?”
Alex slowly pulled his digits out of my wet pussy, and I shuddered at the sensation of his fingers leaving me. “Your breasts didn’t have lumps, but they are...larger than normal.”
I squinted at my own breasts. Even laying down, they were still full and round. “Are they?”
“They are,” he confirmed. “And do you know what that means?”
I shook my head.
“It means you’re at your most fertile,” he said, his hand continuing to play with my erect nipple. Something about it felt wrong—he was my brother, after all—but I didn’t want to object.
It felt too good.
“That’s why you were so wet,” he said. “That’s why you came so easily. You’re fertile.”
“Okay...” I said, and Alex tilted his head to the side.
“Maybe I’m not being clear,” he said, pursing his lips. “You’re at your most fertile right now. If you want to have a child, you should be having sex as soon as possible.“
“I wasn’t...” I paused. Wait, what? “I don’t...I don’t want to have a child?”
Alex looked at me like I was an idiot. “You don’t want to be a mother?”
“Well...”
He sounded so confident, and my head was still fuzzy from the two most powerful orgasms I’d ever experienced. Back to back!
“I mean, eventually,” I finally said. “But not...—”
“Tammy,” he interrupted. “I’m a fertility doctor.“
Shit. How had I forgotten that? My brother’s specialty was fertility—his entire practice was dedicated to helping people conceive.
“So if you came to me,” he continued, “it must be because you want kids.”
“I mean. Eventually, I guess, but...”
“If you came to me,” he repeated firmly. “It must be because you want kids. I’m a fertility doctor.“
The room was spinning. I hadn’t come to him, had I? But if I hadn’t come to him, why was I laying naked on my bed? Why had I let him perform such an invasive checkup?
There was only one answer.
“I...I guess I want to conceive,” I said slowly, each word more difficult than the last. “But....”
My brother paused, letting me piece the thought together.
“I don’t have a boyfriend?”
“Ah,” he said thoughtfully, his eyes traveling up and down my body once more. “Well now. That could be an issue. Is there anyone in your life who you trust enough to be a sperm donor?”
My mind was blank. “Um...”
“No.” Alex waved off the idea. “No, that would take too long. We need someone who’s right here, right now. That’s your best bet of conceiving.”
“Right here?” I asked, my voice cracking. “N-now?”
A huge grin spread across my brother’s face. “Of course!” he said. “I’ve got it.”
I didn’t say anything. Something told me I already knew the answer.
“I can help!”
“But...I’m your sister.”
“It’s okay,” he smiled. “No charge.”
“But shouldn’t...but can’t we...”
“Relax,” Alex said soothingly. “I’m a doctor.”
I nodded slowly, feeling weird. Weird and excited.
He reached out a hand and gently stroked my cheek. “Come on,” he said, pulling his pants down. “Let’s take advantage of your fertile state.”
I watched as my brother stood up, moving his clothes to the floor. I hadn’t seen him naked before, so I wasn’t sure what to expect.
I mean, why would I have seen him naked? He was my brother, ten years older than me.
He had broad shoulders and a narrow waist, and his dick was thick and impressive. It bobbed in front of me as he undressed, and I gulped. This was my brother’s dick. I shouldn’t be seeing it, right?
No. I had to think of it not as my brother’s dick, but as my doctor’s.
Oh, god. I was about to fuck my doctor.
“It’s okay,” he said soothingly, as though he could read my mind. “I’m a fertility doctor. I have plenty of experience with these things.”
Climbing onto my bed, Alex positioned his cock at my entrance. My pussy lips parted easily and he pushed forward. He slid into me smoothly, and I gasped at the feeling of his thickness.
He pulled back, and his cock stopped mid-way, still halfway in.
“You definitely want to do this?” he asked, looking me in the eyes.
“Yes,” I replied. “I...I want to conceive.”
With a smile he pushed forward again, sinking all the way into me. My body protested at the sudden intrusion, but I bit back a cry.
This was my doctor. My brother. And he was fucking me.
I moaned softly as I took him inside, gasping as he filled me completely. He kept pushing until he bottomed out, and I was sure I could feel the head of his cock against my womb.
“Right there,” he whispered, his eyes locked on mine. “Do you feel it? That’s where you’ll be carrying your baby.”
“Oh god,” I sighed, closing my eyes. My brother’s baby. I’d be carrying my brother’s baby.
It felt so strange, yet so natural at the same time. He was my brother, and I loved him. I’d always dreamed of being a mother, I’d just expected it to happen...later. Much later. Maybe in my late twenties, early thirties.
Certainly not when I was eighteen. And I’d never imagine it happening with my brother.
Still...why else would I have gone to a fertility doctor? I wanted to conceive. I wanted to get pregnant.
And my doctor was right here, ready to help make that dream a reality.
“I’m going to fuck you now,” he said, and I nodded eagerly. “I’m going to cum inside you.”
“Do it,” I begged. “Fill me up.”
With a grunt, my brother pulled me close, pressing his body against mine. Our chests mashed together as he thrust upward, filling me up with his thick cock.
“Fuck,” he groaned, his hands gripping my hips tightly. “You’re so warm. So tight.”
I whimpered as he began to move, his cock sliding deep within me. He was bigger than I was used to, but I was so wet, and his cock fit so well. Soon, it would be exploding inside me. Soon, it would be filling me with cum.
My brother’s cum. My doctor’s cum. Thick ropes of hot, baby-making cum.
I couldn’t wait.
“Please,” I panted. “Knock me up.”
“You like that?” he asked, his hips bucking up and down. I nodded vigorously, and he smiled, pumping me harder. “Good girl,” he murmured. “I’m glad you’re enjoying this.”
I loved it. My pussy clenched around my brother’s thick cock, and my toes curled. He was filling me up, and I was ready to be filled.
I needed to be filled.
I needed to be filled with my brother’s semen.
“Cum inside me, Alex,” I begged. “Fill me up. Fill your sister up with your cum.”
It felt so wrong to say it out loud, but there was no denying the truth of my words. I wasn’t just his patient, I was his sister too. And as I lay there on my bed, naked, allowing my brother to fuck me, to put a baby inside me, I knew that this was what I wanted.
I was his sister.
I was fertile.
And I wanted to conceive.
“God, I love you, Tammy,” he groaned, one hand gripping my breast while the other grabbed my hip. “You’ve always been such a good little sister. So sweet and innocent.”
Alex’s lips pressed against my neck, kissing me and making me shiver. His hips picked up speed, slamming into me hard. I cried out, my body clenching as I rode out wave after wave of pleasure.
“And you’ve grown up to be so hot. You’ve got such big tits. Such an amazing body. And you’re so, so…fertile.”
His cock was buried deep in me, and I could feel his orgasm approaching. He was fucking me so hard; I knew I wouldn’t be able to hold back much longer.
“I’m gonna cum,” Alex moaned, his voice growing hoarse. “I’m going to fill you up.”
“Yes,” I cried out. “Fill me up. Fill me up with your cum. With your seed. With your baby.”
He slammed himself against me, and I arched my back as I felt his cock throbbing inside
“I will,” he promised, leaning down toward me. I opened my mouth to moan as his tongue pressed against mine. “I promise. I’m going to knock you up, no matter how many times we have to do this.”
My head spun. Fuck. I hadn’t thought of this being a repeat experience...but now that’s all I could think of. Any time Mom and Dad were out, or even had their back turned, I’d be fucking my brother. Whenever we could, he’d be filling me up. Pounding into me, using every room of the house, until I was finally pregnant.
“I’ll fuck you whenever I can,” he promised, pulling his tongue away from my lips. “Whenever we get a chance. And after this baby, I’m going to give you another. And another and another and another. You’ll be pregnant for the rest of our lives.”
I could imagine it now—constantly pregnant, constantly with child. My brother’s child. My brother’s children.
“Please,” I whispered. “I want to be pregnant forever.”
At that, I could feel my brother tense, and he unloaded into me. His cock pulsed inside me, shooting load after load of cum into my womb. My insides clenched around him, and I felt myself flooding with his seed.
“Yes,” he groaned, throwing his head back as he came. “Fucking hell yes.”
I felt him pulse and spurt inside me, and I cried out as I climaxed, feeling his cum flood my womb.
My body shook as I finished, and I could feel his cock soften inside me. Slowly he pulled out, and I felt empty and unsatisfied.
“That,” he said, climbing off me, “was amazing.”
I nodded. “Yes,” I moaned. “So...so good. Thank you, Alex.”
He grinned, pulling his clothes back on.
“It’s what I do, sis. I’m a doctor.”
