My little sister, Luna, and I were on a trip to our mom’s best friend’s farmhouse. We had a secret relationship, and with my sister being a horny eighteen-year-old beauty—and my own attraction to her undeniable—we couldn’t keep our hands off each other. But she took things a bit too far just as we were about to have a movie night with our mother and her best friend, Cristy.

Luna and I sat close, our hips pressed together, exchanging glances. “I need to get something,” she said, scurrying off to our bedroom. She came back with a blanket. “It’s chilly in here,” she said, gently draping it over us as the room grew darker. Mom just smiled at us, probably thinking how cute we looked, though I suspected Luna had another reason for bringing the blanket.

“Here you go,” Cristy said, handing us a bowl of popcorn.

Luna placed it in the middle. She grabbed a piece, raised it to my lips, and said, “Open.”

I did, letting her pop it into my mouth. I glanced at her briefly, but she just smiled, radiating happiness. It was exactly what my girl used to do. Well, Luna was my girl—or at least, my secret girl for now.

The movie started; it was a romantic comedy. While the blankets covered me and Luna, she gently moved her hand to my crotch, a smile crinkling in the corners of her eyes. I firmly shook my head, but she eagerly nodded. I glanced over at Mom and Cristy who sat tightly together, immersed in the movie. Luna continued, moving closer and closer to my crotch and slipped her hand inside my shorts. I was just too weak. I couldn’t remove her hand. Her fingers reached my bone, and she stifled a giggle and mouthed near my ear, “You’re still hard.”

“What do you mean by still?”

“I felt your bone when we were play fighting earlier,” she whispered.

I rolled my eyes.

Luna's hand wrapped around my shaft, sending tingles through my body. I tried to stay still and not draw attention, but it was getting harder by the second. Her fingers stroked me gently but insistently under the blanket. “You’re taking this a bit too far,” I warned her.

“No,” she whispered. “I used a stealth spell. They won’t notice.”

I gave her a look, thinking she was nuts. But that was a part of her beauty. She had an imagination like no one else, and loved video games as much as I did. I was twenty, so I was two years older than her, but I still loved her quirky humor.

"Everything okay over there?" Mom asked, glancing our way.

"Yep, all good," I managed to say, my voice only slightly strained. Luna gave me a mischievous look and increased her pace.

I tried to watch the movie. The romantic couple were having an awkward first date. But I could barely focus on the plot with Luna's erotic actions. Her thumb swirled over my sensitive tip, spreading the precum gathering there.

I bit my lip to hold back a groan. This was so risky, but I couldn't bring myself to stop her. The thrill of potentially getting caught only heightened the sensations.

Luna leaned in close, her lips brushing my ear. “Do you like it?”

“Yes … This movie isn’t bad.”

“I’m glad you like it,” Mom said, glancing at us again.

"I want you so bad," Luna whispered, her breath hot against my skin.

I turned my head slightly, our faces inches apart. Her blue eyes were dark with desire behind her glasses. It took every ounce of willpower not to kiss her right then and there, or tell her to go quicker and jerk me off till I soaked the blanket in cum.

Instead, I grabbed a handful of popcorn. Luna grinned and tightened her grip, refusing to let go of my joystick.

The movie continued playing, but it may as well have been static on the screen. All I could focus on was Luna's touch and the building pressure in my groin.

In the movie, the romantic couple were sharing their first kiss. The irony wasn't lost on me as I struggled not to make a sound. Luna kept being adventurous, her grip tightening just slightly. I could feel the familiar tension building, a spring coiling tighter and tighter in my core.

"This is my favorite part," Mom commented, her eyes fixed on the screen.

I nodded, not trusting my voice. Luna chose that moment to swirl her thumb over my sensitive tip, and I had to bite my lip hard to stifle a groan. I wasn’t sure if she was aware of how good that felt. It felt as if she was just being adventurous, touching me around and stroking me.

I was so close now, the peak was almost there. I fought to keep my hips still. Just a few more strokes and I'd be done for.

Suddenly, Luna's hand stilled. She leaned in close, her lips brushing my ear. “Can you touch me?”

I hesitated, knowing how risky it would be to return the deed under the blanket with Mom and Cristy right there. But the temptation was too good to resist.

Slowly, I slid my hand over to rest on Luna's thigh. She shifted slightly, allowing me better access. I traced circles on her smooth skin, gradually inching higher under her dress.

Luna resumed her cock stroking. She gave my entire shaft an equal amount of attention, but she was most fond of the sensitive crown. I bit back a groan as I finally reached the edge of her panties. She was already wet, the fabric damp beneath my fingers.

The movie's climactic scene was playing out. The swelling music helped mask our quickened, horny breathing.

I slipped my fingers under her panties, finding her slick folds. Luna broke out in a smile of pleasure as I began slowly circling her most sensitive spot.

We kept pleasuring each other. I could feel my release building, hot-taboo pressure coiling tighter with each stroke.

"Oh, I love this part," Mom sighed, completely engrossed in the film's romantic ending.

Her voice jolted me back to reality. What were we doing? This was insane. But I was too far gone to stop now. I was at a point of no return.

With a few final, desperate strokes, Luna pushed me over the edge. I came. I bit down hard on my lip to stifle any sound as intense waves of pleasure crashed over me. My cock pulsed in my little sister’s hand, spilling hot streams of cum beneath the blanket. She stroked me through it, milking every last drop as I shuddered silently beside her.

I carefully glanced to my left, and thankfully, Mom and Cristy were still immersed in the movie, and they hadn’t noticed. Luna leaned closer and whispered, “I told you the spell worked.”

I wanted to laugh. I wanted to tickle her till we both squirmed on the floor, tumbled out of this house and rolled down a hill. I turned my attention to her, my left hand was still on her flower, and she was moistening like never before. I refocused my attention on pleasuring Luna, deciding to give her a dose of her own medicine. I increased the pressure and speed of my fingers against her clit, feeling her thighs begin to tremble. Her breathing grew ragged as she neared her peak.

Just as the movie reached its romantic climax, Luna's body went rigid. She pressed her face into my shoulder to muffle her moans as she came. I felt her inner walls fluttering against my fingers as waves of pleasure washed over her. Luckily, I had the skill to pleasure a woman with my one hand, but it was more challenging without lips and tongue. The excitement must have helped her.

We sat frozen for a long moment, hearts racing as we came down from our shared high. Slowly, carefully, we withdrew our hands and readjusted our clothing under the sticky blanket. Because of the dim lighting, the wet blotch was slightly hidden, but I knew it would be a challenge to get out of there without them seeing my huge load covering my shorts and probably her hand.

"Wasn't that just the sweetest ending?" Mom sighed contentedly as the credits began to roll.

"Yeah," I said. "Really... satisfying."

Luna giggled beside me, squeezing my hand under the blanket. I knew we'd have to be more careful in the future, but for now, I was riding the high of our forbidden pleasure. As risky as it had been, I couldn't deny the thrill of our secret intimacy.

“Are you tired?” Mom asked me as she raked her fingers through my sweaty hair. Thankfully, it didn’t raise any eyebrows.

“I’ll hop into bed soon,” I said, feeling a bit uncomfortable in case she would either smell or feel the blanket.

“And you, Luna?” Mom asked her.

“I’m also growing tired,” she said. “I loved the movie though.”

They talked a bit about it, discussing which scenes they loved the most. I was surprised at how well Luna had concentrated while stroking my cock. Mom and Cristy took the popcorn bowls to the kitchen and helped each other clean them. “I have to go to the bathroom first,” I told Luna in a lowered voice.

“I have to pee,” she said.

I dropped my voice even lower. “There’s a big blotch of buttermilk under the blanket.”

“That’s right,” she said.

I took the blanket with me, just in case, and I was glad I did so since Mom stepped out of the kitchen. “Are you gonna brush your teeth?” Mom asked.

“Ugh, yeah,” I said and awkwardly held the blanket in front of me.

“Okay, I just wanted to say goodnight since I’ll go to bed too.”

“Sure, good night.”

“And sweet dreams.”

“You too,” I said. I opened the door and went inside, sighing a breath of relief. When I stood in front of the mirror, my eyes widened to saucers. There was so much cum, soaking my shorts and the blanket. I’d never fired a load like that in my life.

Taking off my clothes, I tried my hardest to wash off any traces, both from the blanket and my shorts. Eventually, my sister knocked. “Psst, can I come in?”

“Is Mom there?”

“They’re in the bathroom on the second floor. The coast is clear,” she said.

I opened the door and she hopped inside. She rushed to the bathroom, lifted the hem of her dress and pulled down her honey-stained panties. She sat down with a sigh and let go. “Ah, finally,” she said.

I could see the cum stains on her hand, hoping Mom hadn’t spotted it. “I can’t believe we did that,” I said, finding it oddly erotic seeing her pee.

She gave me a relaxed look. “I told you I used the invisible spell.”

I wanted to tell her that this wasn’t a computer simulation, but decided not to. I found her imagination funny.

“Admit it was exciting.”

“Yes,” I said and couldn’t deny that fact. “But it was still risky.”

She just shrugged and didn’t see it the same way I did. “I can’t believe you made me climax with just your hand … I usually need toys or something.”

“Mind telling me what something is?”

“Like porn, Switch controller, or some nice uneven object that hits the spot.”

I thought back to the day we played Switch together, and when I noticed the controller was sticky. “Wait, that day when I noticed the controller was sticky, I thought you said it was from perfume.”

“Pika, pika,” she said and made an innocent Pikachu face, making us both laugh. After we’d laughed, she added, “I owe you an apology. I thought you would think I was weird for doing it. But I did push that controller inside me the other night.”

“I forgive you,” I said, and her sexual adventure just hardened my cock.

She let go of the last drops and put on her nightgown. We brushed our teeth together and then went into our bedroom. I was still shocked at what we’d been up to. I realized how wrong it could go. “I still can’t believe we went that far.”

“I think I need to help you get your mind on something else,” she said cleverly.

“How?”

“Tickles!”

I barely had time to react before Luna pounced, her fingers finding all my most ticklish spots. I squirmed and tried to stifle my laughter, not wanting to alert Mom or Cristy. My cock suddenly hardened despite the recent climax. The friction of her thighs against mine sent blood flowing to my cock.

Luna just continued to tickle me. While her fingers kept dancing all over me, I noticed how she dry-humped me as well, rubbing her crotch against my leg. She wasn’t wearing any panties either, smearing her nectar all over me. I writhed beneath her, torn between wanting to escape and enjoying the closeness. I started laughing hysterically, making my jaw and abs ache.

"Stop!" I gasped between giggles, trying to fend off her relentless tickle attack.

Luna grinned mischievously. "Never. I need to cure you!"

We rolled around on bed as I tried to escape her tickling fingers. Eventually, I managed to grab her wrists, pinning her beneath me. We were both breathing heavily, faces flushed from laughter and exertion.

"Gotcha," I said triumphantly.

Luna's eyes sparkled as she gazed up at me. "Oh really?"

Before I could react, she leaned up and captured my lips in a deep kiss. I melted into it, releasing her wrists to cup her face instead. Her arms wrapped around my neck, pulling me closer. Suddenly, someone knocked on the door, and we both gasped and turned to the door. I was lying right on top of her, my bulge straining against the underwear, poised right at her wet womanhood. Her nipples strained against her nightgown, and anyone who opened the door would realize we were up to something, and it wasn’t just play fighting.

“Please,” Mom said without opening the door. “You have to tone it down.”

“Sorry,” Luna squeaked.

“Goodnight you two,” she said.

“Goodnight,” I said.

We held our breath, listening to every step as she ascended the stairs, and finally, she closed the door. We looked each other in the eyes, and my lips fell on hers again, and we continued from where we left off.

Luna's lips were soft and eager against mine as we resumed our passionate kiss. My hands slid down her sides, savoring the curves of her body through the thin nightgown. She arched into my touch, a soft moan escaping her lips.

"We should be quieter," I whispered against her lips, even as my hips ground against hers instinctively.

"Then you'd better keep my mouth busy," she teased, pulling me back down for another deep kiss.

We continued to kiss, for who knows how long, squeezing out as much love as possible till we were both out of breath. I came off her mouth, satisfied and rolled to the side.

“What were the odds of her not opening the door?” I asked her, knowing Luna had inherited Mom’s disdain for knocking on doors.

“I don’t know,” she said. “Why think of that though? That was my favorite kiss so far.”

I just smiled. “It was great,” I said, licking my sister’s sweetness from my lips.

“Chase?” she asked.

I turned to her, caressing her thighs. “I’m listening.”

“Do you think we can have sex?”

I blinked at her. “You just gave me a handjob, and Mom was a second away from walking in on us kissing.”

“But that was because you were laughing hysterically.”

“Uh, yeah? After you hysterically tickled me.”

“Come on, we were just having fun.”

I considered it. It sure was tempting, sliding in and out of her after such a day. “Let’s wait at least two hours, so we know they’re asleep.”

“Two?” she said. “How about one?”

“Fine,” I said.

She started a timer on the phone and just smiled. While we were waiting, we talked about various topics. We lay side by side, looked at each other as we discussed video games and feelings.

Eventually, she started touching my chest and arms. “You look nice,” she said out of nowhere.

“So do you,” I said. I also wished time moved quicker. I started getting in the mood again. “How much time left?”

“It’s only been like ten minutes,” she said.

I sighed. Suddenly, I started hearing some noises coming from outside. We had the window open, and I glanced at it. “What’s that?”

We held our breaths and started hearing the slow moans.

“It sounds like our mother is masturbating,” Luna said and listened further. “Yep, it definitely sounds like her.”

“But it’s coming from outside,” I pointed out.

“But her bedroom is right above ours. She might keep her window open, so the noise spills outside instead.”

I swung my feet off the bed and gently opened the window. Luna was right. It came from upstairs, and by the sound of her moans, it definitely sounded like our mom. Luna joined me, padding to the window.

“Yeah, it’s definitely, Mom,” she said in a lowered voice.

“Ah, oh, ah,” she moaned, trying to stifle her sounds of pleasure as I imagined how she worked a sex toy in and out of her womanhood.

We stood silently by the window, listening to Mom's soft moans and gasps drifting down from above. I'd never heard Mom like this before, and it made me aroused.

Luna leaned in close, her breath tickling my ear as she whispered, "She usually goes for about ten minutes when she does this."

I turned to look at her, eyebrows raised. "How do you know that?"

She shrugged, a mischievous glint in her eye. "I may have timed her once or twice."

I shook my head, torn between amusement and disbelief at my sister's boldness. Above us, Mom's breathing grew more ragged, her moans becoming more intense.

"Oh god," Mom's voice floated down, breathless and filled with need. "Yes, right there..."

Luna pressed closer, her hand sliding down to cup my growing erection through my shorts. "Seems like someone's enjoying the show," she teased.

“Not true,” I said firmly. “I was erect from the start.”

“Why are you blushing so hard then?” she asked.

“Forget about it,” I said. But both of us still listened till she reached the peak.

“That’s her climax,” she said matter-of-factly.

“Oh,” she moaned, which I knew could’ve been louder. She let out a sigh of relief and collapsed onto the bed, probably falling asleep shortly after.

I wiped a sweat from my brow. I couldn’t deny it had been hot listening to my mother masturbate. We hopped into bed again. “Does she do that once a day?” I asked her.

“Sometimes more,” Luna said.

“Alright, let’s try not to meddle though. It’s not like we don’t masturbate.”

“You’re kind,” she said and wrapped her arm around me. “And warm … let’s lie like this for the next forty minutes.”

“Sure,” I said.

Those forty minutes passed quickly. Luna warmed me better than a blanket, her soft tits gently mashing against my chest. Her breath was sweet and kept descending down my neck, and I felt the gentle beat of her heart right on top of mine. Both my hands caressed the curves of her bottom. There was no better position than this, and my blood slowly flowed southward, my cock hardening against her.

The alarm went off, and she quickly turned it off, so we didn’t wake up anyone else. “Are you awake, bro?”

“I am,” I said.

“I am sweaty since I’ve been lying on you for so long.”

“I don’t care,” I said and waved my hand dismissively. “Are you wet?”

“Uh-huh,” she said and gently rubbed her peach against my leg. “Help me take off my nightgown.”

She sat up, and I pulled it over her head, freeing her beautiful breasts that I cupped in my hands. I sank my fingers into them. They were so satisfying to squeeze, making my hands melt. When I kept playing with them, she twirled her hair on her finger. She kept glancing down at my cock, and eventually, she reached for the waistband of my underwear and tugged them down. I helped her pull down my underwear, freeing my bone. “Gotcha,” she said and started pumping me.

We gently lay down, me on top of her.

“Can we do another position?” she asked, biting her lip as I was about to enter her. “On the side, so I can see myself get fucked in the mirror.”

“Fine,” I said in a husky voice. “But let’s do missionary first.”

I gently rubbed the head of my cock against her nectar, coating it thickly. She was soaked, and I pushed inside her, feeling her warmth envelop me. It felt just as intense and forbidden as when she’d given me a handjob. Luna let out a soft moan, her legs wrapping around my waist to pull me deeper. I started with slow, measured thrusts, savoring the feeling of being joined with her again.

"Oh Chase," she breathed, her hands roaming over my back. "I've been waiting for this all day."

I pressed my lips to hers in a deep kiss, muffling our moans as I picked up the pace. The bed creaked softly beneath us, but we were too lost in each other to care. Luna's hips rose to meet mine, matching my rhythm.

After a few minutes, I remembered her request. "Ready to switch positions?" I whispered.

She nodded eagerly. We carefully rearranged ourselves, lying on our sides facing the mirror. I entered her from behind, lifting her leg so I could reach her slit a bit better. Luna's eyes were fixed on our reflection, watching as I slid in and out of her.

"God, we look so hot together," she murmured. “Sibling love.”

I nuzzled her neck, leaving a trail of kisses along her shoulder. "You're beautiful," I told her, my voice husky with desire.

We moved together, finding a steady rhythm that had us both panting with pleasure. I could feel the familiar tension building in my core, my release approaching fast. Luna's inner walls were starting to flutter around me. “Are you getting there?” I asked her.

“Uh-huh,” she said. “You’re stretching me real good.”

“There is no pussy sweeter than yours.”

“I don’t like pussy, say kitty.”

“Kitty then,” I said with a chuckle as I kept sliding in and out of her, the pleasure intensifying. Suddenly, both of us heard the stairs creak, and I froze suddenly. “What’s that?”

“What’s what?” she asked, mildly disappointed that I stopped fucking her.

“I swear that I heard something,” I said, and we held our breaths. We both heard it, the stairs creaking as someone descended the stairs. We both exchanged glances.

“What time is it?” I whispered.

“Two in the morning,” she said, lowering her voice to a scarcely audible whisper.

“But the bathroom is upstairs,” I said. This would be difficult to explain—I was rock hard and she was soaked. We were both covered in a light sheen of sweat and the scent of musk had filled this room. This took sibling love to another level. Both of us were warm to the touch and even a child would understand that there was something else going on in this bedroom than a good night’s sleep. This for some reason just made her more excited. She faced me with her eyes glimmering as if it were Christmas Eve.

I quickly pulled my cock out from her love hole and pulled the sheets over us in case Mom would enter.

“It doesn’t sound like mom though,” Luna said.

I listened as the mystery lady descended the stairs. “You’re right. It sounds like Cristy.” She walked past this room and both of us froze. We could then breathe when we heard how she approached the foyer and put on her shoes.

“Is she heading out for a walk?” I wondered.

“Let’s check,” she said. She rolled out of bed and went on her toes to the window. I didn’t like this at all, but I just realized that the horse stable and garden were overlooking this bedroom. I followed her and got on my knees as I watched out the window. It was Cristy. She wasn’t dressed in anything except for boots, and I could see her full moon in its full glory—brighter than the moon in the sky.

“What an ass,” I said, as I watched her cheeks jiggle with every step.

“Don’t you think it is a bit blubbery?”

“Afraid of competition?” I teased her, which was about time.

She seized my cock and gave it a stroke of affection. “Nope, you’re mine.”

Cristy headed into the stable and came back with a couple of riding equipment. Luna was already ducking, taking my cock in her mouth. “What are you doing, ah, ah.” She sucked me so hard that her cheeks hollowed out. As I looked up and wanted to catch a glance at Cristy’s delicious breasts, I met her eyes for a brief moment and saw a smirk spreading on her lips. I quickly ducked, my heart pounding in the middle of my chest. Luna was still blowing me, and I had to push her away. “What are you doing?”

“I just didn’t want that woman to take the attention away from me,” she said and made a little sad face while licking her lips.

“She’ll be inside any minute. Let’s jump back to bed so we don’t get caught here.”

As Cristy entered the door, we snuck into the bed again. I didn’t know how I was going to tell Luna that Cristy had seen me. If she hadn’t given me that surprise blowjob, I would have found time to hide as well. Cristy approached the stairs but stopped by our door. Both of us exchanged glances, but she then went up the stairs. “What was that?” Luna mouthed and wondered why she suddenly stood there.

“Be glad she didn’t walk in on us,” I said firmly.

“Admit it was thrilling though,” she said.

“It sure was,” I said.

Just when she mentioned it, my cock hardened to steel, and she felt it when she tightly caught it in her grip. “You don’t have to tell me anything—that confirms it.”

“Alright, should we fuck again or just whisper to each other for the rest of the night?”

“Let’s have sex again.” She rolled to the side and backed her ass against my raging hard-on. She lifted her leg and I searched her slit with my cock. The head touched her lips and parted them. Holding her leg, I then pushed it inside, and her pussy soaked my cock. She was so drenched that I just slid in. While holding her leg and thrusting her, I explored her body, cupping her breasts and flicking her stiff nipples.

“Hmm, my brother’s hard penis, ah, ah,” she moaned in joy as the pleasure interrupted her speech.

I was as hard as before even though I’d already emptied myself earlier on the blanket. The only difference now was that it took more effort to feel the orgasm building.

“They must be deaf if they don’t hear us,” I said and plunged my cock inside her again. I reached her deeper and deeper, and her walls tightened around my shaft.

“Let’s blame the gods for making this feel so good,” she said and grasped her pillow, her entire body throbbing with desire. “Can you try to push it deeper?”

“You sure I’m not hurting you?”

“No,” she said between her moans.

I lifted her leg till her knee bonked her face. It gave me more room, and I pounded her harder and deeper. “Better?”

“Uh-huh.” She didn’t say much now as just moans and cries of pleasure escaped her sexy lips.

“Not so loud,” I warned her and tried to keep the flesh-smacking to a minimum.

“I used the stealth spell, it’s okay. I saved some mana from earlier.”

I rolled my eyes. “Luna, I love you.” Her words just made me fuck her harder.

She dug her nails into the pillow, ripping a hole into it. She bit down hard on her bottom lip, trying to suppress the wave of pleasure building inside her. But as it crashed over her, she couldn't stop the loud moan from escaping her throat, echoing in the dark room.

“Jesus, Luna,” I tried to warn her. I prayed she wasn’t playing me with her stealth spell. If I wasn’t about to climax myself, I would have stopped right away. But it was too intense. It felt so good to fuck her.

She let go of the pillow and slumped back. It was then my turn to orgasm. I jolted and spilled my second load inside her. “Gosh,” I moaned as her soaked pussy couldn’t stop hugging my erection.

I slowed down, letting her sex milk me of the last ropes of cum. Just when I was about to come down from the high, I heard how the floor squeaked right outside the bedroom. Both of us gasped, and this time we weren’t saved by luck. Someone pressed down the door handle, and the door opened and a hand reached for the switch.

“I’m trying to sleep—” Cristy said, but when she discovered both of us, with my erection stuffed deep inside my little sister and my right hand holding onto her breasts, Cristy stiffened on the threshold. Neither Luna nor I found words as a deep blush covered every inch of our faces.

“Oh gosh, I’m so sorry,” Cristy said and her right hand flew to her mouth.

“We’re finished,” Luna said awkwardly.

“Sorry for the noise,” I said just as awkwardly as my sister.

Cristy raised her hands in an apology. “It’s okay. And don’t worry, I won’t tell your mom about this … But be a bit more discreet next time.” She slowly closed the door while she saw the girth of my thick cock thrust deep into my sister. Her eyes lit up, and I’d never seen a woman close a door so slowly. She retreated up to her bedroom, and I could finally take my cock out of Luna’s wet slit and breathe in the awkward air that still lingered in this room.

“Did you run out of mana?” I asked her after a long awkward minute.

She lightly punched my shoulder. “No, I didn’t. She must have used a superior spell.”

“Whatever,” I said. “There's nothing we can do about it now.”

“She promised not to tell Mom, so I guess we’re safe for now. If you’re worried about our mother finding out.”

“I suppose,” I said and felt bad for hiding this relationship and possibly waking them with our sounds of lust. “Let’s get some sleep.”

“I agree,” she said and cuddled up to me.
