Medicine for Cramps

I stood frozen in the doorway of Anna's bedroom, my heart hammering against my ribs like a trapped animal. Sammantha had her arm around our daughter, both of them sitting on the edge of the bed. Anna looked so small, so fragile in her oversized pajama shirt—a faded NASA logo stretched across her chest. Her glasses were slightly askew, and her usual ponytail was a mess of brown tangles. She clutched a heating pad to her lower belly, but I could see the tears glistening in her eyes.

"It's okay, Daddy," she said again, her voice trembling but certain. "Mommy explained everything. If it helps... I want you to."

My daughter was having menstrual cramps and my wife had convinced me that sex was going to help. What kind of family are we?

I swallowed, my throat dry. Fuck. The word daddy hit me differently now—a knife twisting in my gut, but also something else. Something hot and shameful that pulsed low in my groin. I hated that part of me. The part that was already half-hard just from the thought of what they were suggesting.

Sammantha stood, smoothing her skirt—that tight pencil skirt she wore when she wanted to look professional, but now it seemed almost predatory. She walked toward me, her heels clicking softly on the hardwood floor. Her hand found my chest, fingers splaying over my shirt.

"Sweetheart," she said, her voice low and soothing, "we've been married for eighteen years. You think I don't know how much you love her? How much you'd do anything for her?" She looked up at me, her eyes steady. "This is no different than giving her medicine. It's just... a different kind of medicine."

"But she's our daughter, Sam." My voice cracked.

"And she's in pain. Real pain. Cramps so bad she can't even stand up straight." Sammantha's hand slid down to my belt, fingers playing with the buckle. I felt myself stiffen further. "You've seen her double over. You've heard her crying at night. This works. I've read about it—the prostaglandins, the uterine contractions, the endorphin release from orgasm. It's science."

I glanced past her shoulder at Anna. She was watching us, her cheeks flushed—from embarrassment or pain, I couldn't tell. She bit her lower lip, the way she did when she was nervous about a test. My little nerd. My brilliant, awkward, sweet girl who still asked me to help with her calculus homework.

"Daddy..." She shifted on the bed, wincing. "It hurts so bad. Mommy said you'd make it feel better. Please?"

The sound of her voice, pleading like that, broke something inside me. I felt my resistance crumble, replaced by a dark, hungry need. My cock was fully erect now, straining against my jeans. Sammantha noticed, of course. She always noticed.

"See?" She whispered, unbuttoning my jeans with practiced ease. "Your body knows what to do, even if your mind is still fighting it."

She pulled down my zipper, the sound loud in the quiet room. I didn't stop her. I couldn't. My eyes were locked on Anna as Sammantha pushed my jeans and boxers down my thighs, freeing my thick, hard cock. It jutted out, glistening slightly at the tip. Anna's eyes went wide, her mouth falling open.

"It's okay, baby," Sammantha said, guiding me toward the bed. "You've never seen one before, have you?"

Anna shook her head slowly, her gaze fixed on my erection. "It's... big."

Fuck. The way she said it, innocent and awed, sent a jolt of raw lust straight to my balls. I was trembling, caught between horror and the most intense arousal I'd ever felt.

Sammantha sat beside Anna on the bed, stroking her hair. "He's going to help you, sweetie. Just like I told you. You'll feel a little discomfort at first, but then it'll get better. So much better." She kissed Anna's forehead. "Lie back, honey."

Anna obeyed, pulling the heating pad aside and lying flat on the mattress. Her pajama shorts were light pink cotton, and I could see a damp spot forming at the crotch—the blood from her period seeping through. My mouth went dry.

I stepped closer, my cock bobbing in front of me. The room smelled like lavender and something metallic—the blood, maybe. Or her fear. Or my sweat.

"Daddy?" Anna looked up at me, her eyes glistening. "Will you... will you be gentle?"

I nodded, my voice gone. I could barely breathe. Sammantha reached up and took my hand, guiding it to the waistband of Anna's shorts.

"Take them off," she said softly. "Slowly."

My fingers fumbled with the elastic, tugging the shorts down over Anna's hips. She lifted her bottom slightly to help, and I pulled them down her pale thighs, past her knees, off her ankles. The bloodstained crotch of the shorts left a red smear on her inner thigh. A cotton panty liner was stuck to her underwear—a plain white pair with little cartoon cats printed on them. My daughter wears cat underwear. The thought made me dizzy.

Sammantha peeled the underwear down next, exposing Anna's bare pussy. Her pubic hair was sparse—a light brown fuzz, still girlish. Her lips were pink and swollen, and a thin trail of dark blood trickled from her slit.

"See?" Sammantha murmured, spreading Anna's legs gently. "She's ready. The blood will act as lubricant. It's natural."

I stared at the sight of my daughter's virgin cunt, slick with her first period, open and waiting. My cock throbbed painfully.

"Get on the bed," Sammantha instructed, shifting aside. "Between her legs."

I crawled onto the mattress, my knees sinking into the soft comforter. Anna's legs fell open wider, instinctively. Her hands were clenched at her sides, her knuckles white.

"It's okay, Daddy," she whispered again. "I trust you."

I positioned myself over her, my cock hovering just above her entrance. I could feel the heat radiating from her body, smell the coppery tang of her blood. I looked into her eyes—those big, brown, trusting eyes—and I hesitated.

"I don't know if I can..."

"You can," Sammantha said from beside me. Her hand found my hip, pushing gently. "Do it. For her."

I pressed forward. The tip of my cock touched her wet, warm folds. Anna gasped, her body tensing. I pushed again, and her lips parted, my head sliding inside. She was so tight, so impossibly tight, and the blood made it slick but not easy. I could feel every ridge, every clamp of her virgin muscles.

"Ah—" Anna's cry was sharp, her back arching off the bed.

"Shh, shh," Sammantha cooed, stroking her cheek. "Breathe through it, baby. It'll feel better in a minute."

I held still, buried halfway inside her, my balls pressed against her ass. Her cunt was pulsing around me, hot and wet, and I could feel the blood coating my shaft. It was the most forbidden, filthy thing I'd ever done, and I was harder than I'd ever been in my life.

"More," Anna whispered, her eyes squeezed shut. "Just... do it, Daddy. Get it over with."

I drove deeper, my hips meeting hers with a wet slap. She screamed—a short, sharp sound that cut off into a sob. Sammantha held her, whispering reassurances, while I began to move. Slow at first, then faster, the blood making a squelching sound with every thrust.

I fucked my daughter. Her first time. Her first period. And it was the most shamefully exquisite thing I'd ever experienced.

After a few minutes, her sobs quieted. Her body relaxed. She started to moan—small, breathy sounds that told me the pain was fading, replaced by something else. Something that made her hips start to meet mine.

"See?" Sammantha said, her voice proud. "It's working. She's feeling better, aren't you, honey?"

Anna nodded, her eyes glazed. "Yeah... it... it doesn't hurt anymore mummy. It feels... good."

Oh God. I was going to come. I couldn't stop it. My rhythm faltered, and I buried myself deep inside her, spilling my cum into her cunt, mixing with her blood. I groaned, the sensation overwhelming, and collapsed onto my elbows, panting against her shoulder.

Anna's hand came up, trembling, and patted my back. "Thank you, Daddy."

I couldn't speak. I could only lie there, still inside her, and feel the weight of what we'd just done.

Sammantha stroked my hair. "You did good, sweetheart. Both of you."

But as I pulled out slowly, watching my cum and her blood trickle down her inner thigh, I knew this wasn't just a one-time thing. The look in Anna's eyes—the hunger starting to form there—told me she'd want more.

And fuck me, so would I.

The days after that first time were a blur of guilt and craving. I'd catch myself staring at Anna across the dinner table, remembering the way her tight little cunt gripped me, the sound of her moans. And she was always near me now—brushing past me in the hallway, pressing her small body against mine when she hugged me goodnight. Her hugs lingered longer than they used to, her arms wrapped tight around my waist, her face buried in my chest.

Sammantha noticed, of course. She noticed everything.

One evening, after Anna had gone to her room, Sammantha found me in the kitchen, staring blankly at the sink. She came up behind me, her hands sliding around my waist, her lips brushing my ear.

"She's been touching herself, you know," Sammantha whispered. "I saw her through the crack in her door last night. Little fingers rubbing her clit. She's horny, sweetheart. Desperate."

I swallowed hard. My cock twitched in my jeans.

"If you don't help her," Sammantha continued, her voice low and serious, "she's going to find someone else. Some boy at school. And you know what happens then. She'll become a hoe, spreading her legs for anyone who looks at her. Is that what you want?"

"No." The word came out rough, automatic.

"Then go to her. She needs her daddy." Sammantha kissed my cheek and stepped back, giving me a gentle push toward the hallway. "Go."

I walked on autopilot, my heart pounding. The door to Anna's room was slightly ajar, a sliver of warm lamplight spilling out. I pushed it open slowly.

And there she was.

Anna lay on her bed, her legs spread wide, her pajama shorts and panties tangled around one ankle. Her fingers were buried between her thighs, sliding through slick folds, her other hand clamped over her mouth to stifle her moans. Her eyes were closed, her cheeks flushed, her breath coming in ragged gasps.

I stood frozen in the doorway, my cock straining against my zipper. She looked so innocent and so filthy at the same time—my little nerd, lost in pleasure.

Then her eyes fluttered open. She saw me. For a second, her hand stopped, her face going red.

"Daddy..." Her voice was breathy.

I crossed the room in three strides, dropping to my knees beside the bed. Her fingers were still glistening with her juices, and I could smell her—that sweet, musky scent that made my mouth water.

"Let me help you, baby," I said, my voice ragged. "Daddy's here."

Anna's eyes lit up. I crawled onto the bed, positioning myself over her face, my cock bobbing inches from her lips. She looked up at it with the same awed expression she'd had the first time, her tongue darting out to wet her lips.

"You want this?" I asked, my voice thick.

"Yes, Daddy. I want all of it."

I lowered myself, and her mouth opened, taking me in. Her lips wrapped around the head, her tongue swirling, tasting. She was clumsy at first—teeth scraping, gagging when I pushed too deep—but she learned fast. Her hands gripped my ass, pulling me deeper, and she moaned around my cock, the vibrations sending jolts of pleasure through me.

"Oh fuck, baby... just like that..."

I could feel her working me, her throat relaxing as she took more of me. She was eager, hungry, swallowing me like she'd been starving for it. I looked down and saw her eyes closed, her cheeks hollowed, drool running down her chin.

Then I remembered—I wanted to taste her too.

I pulled out slowly, her lips clinging to the tip, and she whimpered at the loss. "Don't stop..."

"I'm not," I said, shifting my body around. "I'm going to eat you while you suck me."

Her eyes went wide with excitement. She scrambled to position herself on top of me, her knees straddling my head, her wet pussy hovering just above my mouth. I grabbed her hips and pulled her down, burying my face between her thighs.

Her taste hit me like a wave—sweet and tart. She was soaked, her clit swollen and poking out from its hood. I licked a long stripe from her entrance to her clit, and she let out a gasp, her hips bucking against my face.

"Oh, Daddy!" Her voice was muffled as she lowered her mouth back onto my cock.

I ate her like she was the last meal I'd ever have. My tongue circled her clit, flicked it, pressed flat against it while she writhed above me. Her thighs squeezed my head, her juices coating my chin. She sucked me with increasing confidence, taking me deep until her nose pressed against my pubic bone, gagging but refusing to let go.

I felt her start to tremble, her rhythm faltering. "I'm gonna cum, Daddy... I'm gonna—"

I sucked her clit into my mouth, and she screamed—a muffled scream around my cock—as her orgasm crashed through her. Her body clenched, her hips grinding against my face, and she came hard, flooding my tongue with her release.

I didn't stop. I lapped it up, drinking her, and kept licking until she collapsed, panting, her head falling to my thigh.

But I wasn't done. I was harder than ever, my cock slick with her saliva. I flipped us over, pinning her beneath me, and looked into her dazed eyes.

"Now I'm going to fuck you, Anna. And you're going to take it all."

She nodded eagerly, her legs spreading wide. "Yes, Daddy. Fuck me."

I didn't hesitate. I lined up my cock with her dripping slit—slick from her cum and her arousal—and thrust in with one smooth motion. She was still tight, but wetter now, her body welcoming me. She cried out, a mix of pleasure and relief, and wrapped her legs around my waist.

I fucked her hard. No slow, gentle movements this time. I drove into her with a desperate need, my balls slapping against her ass, her breasts bouncing beneath her shirt. She arched her back, her hands clutching the sheets, her mouth open in a silent scream.

"Yes, yes, yes, Daddy, don't stop!"

I angled my hips, hitting that spot inside her that made her eyes roll back. Her cunt clenched around me, milking me, and I knew I wasn't going to last long.

"Cum for me, baby," I growled. "Cum on Daddy's cock."

Her body obeyed instantly. She shattered beneath me, her pussy spasming, her nails digging into my arms as she screamed my name. The feeling of her coming undone pushed me over the edge. I buried myself deep and unloaded—hot, thick ropes of cum filling her, mixing with her own.

I collapsed on top of her, both of us panting, slick with sweat and cum. She held me, her legs still locked around me, her fingers stroking my back.

"Thank you, Daddy," she whispered, her voice sleepy and content.

I kissed her forehead. "Always, baby."

But as I started to pull out, her legs tightened. "No," she said, looking up at me with a new hunger in her eyes. "Again, Daddy. I want it again."

My cock, still half-hard and buried inside her, twitched at her words. I looked down at her—my daughter, my little nerd, now a greedy little slut for my cock—and I knew I was lost.

"Again," I repeated, a dark smile spreading across my face. "Of course, baby. As many times as you need."

And I rolled onto my back, pulling her on top of me, ready to let her ride me until she was satisfied.
