Bonding with my elder sis

My name's Chase, and I'm 19 years old. Last night, I had just gotten back home for the summer. Two years ago, right after I graduated from high school, I moved away to Southern California alone while my mother and big sister, Luna, stayed in Sacramento.

I was just glad I could spend more time with my quirky big sister who’d been 26 for a few months now.

I woke up in my good old bedroom, and as soon as I heard someone knock on the door, I rubbed my eyes. At first, I thought it was my bedroom door, but I quickly realized it was Luna’s. It was a bit difficult to tell whose room it was since I hadn’t slept here in a while.

“Luna?” my mother said in her peaceful morning voice. She gently knocked again. “Luna, can I come in?”

“What is it?” my sister answered in a suspicious tone. It sounded like she’d been up to mischief. It was normal for her to get caught with her hand in the cookie jar. She loved all-nighters and was the one who first persuaded me to pull them, pretending to be asleep while Mom went to bed, then sneaking down the stairs to play games all night.

“I want my toy back.”

Luna didn’t answer right away. “I don’t know what you’re talking about.”

“Darling, you know what I’m talking about.”

“No, I don’t,” she said.

Mom slowly opened the door, and I heard her stop at the threshold. I could imagine her placing her hands on her hips. “I don’t have time for this… Can you please give back my vibrator?”

My eyes widened. I never thought my sister would "borrow" our mother’s toys.

“I still don’t know what you’re talking about,” Luna said, with a hint of embarrassment in her voice.

“If it wasn’t you… Who was it then, Princess Zelda?”

“No… Link is all the vibrator she needs.”

They both chuckled. “Very funny… Listen, I’m running late, and you know I don’t have all the time in the world.”

A silence followed.

“Fine,” Luna said, and I heard her hand something over to Mom.

“Thank you,” Mom said. “Why don’t you just ask me to buy you one instead of sneaking into my bedroom?”

“I’m sorry,” Luna replied, sounding more upset than embarrassed.

“Let me know which one you want, and I’ll get it for you, okay?”

“Okay… Uhm, can you get me vibrating panties too?”

“How do you know what vibrating panties are?” Mom asked.

“I… might have borrowed those too… Again, I’m sorry.”

“I forgive you, but you know we aren’t millionaires. It’s either vibrating panties or a vibrator. Choose one.”

“Okay, a vibrator,” Luna said.

I heard Mom kiss Luna’s cheek. “And please, don’t just play video games with your brother all day.”

“I promise,” Luna said.

“I made some pancakes for you two.”

“I can smell the eggs and flour on your hands,” Luna said.

“I have to wash my hands and then I have to bounce. I’ll see you later this evening.”

“Have fun with Christy,” Luna said.

“Ok, bye bye.”

I let my head slump back onto the pillow. I found it oddly erotic that my sister had snuck into Mom’s bedroom to take her vibrator and vibrating panties behind her back.

Luna suddenly opened the door and poked her head inside, bursting my dream bubble. But what appeared in front of me was better than a dream. Wearing round glasses, she stood before me in a purple nightgown, its thin straps stretched over her shoulders. The dress had once been snug and flattering, but now it barely covered her hips, and the neckline gaped open as if struggling to contain her ample chest. Her glossy brown hair tumbled around her face in wild waves, and she offered me a coy smile with her pink lips.

“Are you awake, sleepyhead?”

I rolled my eyes. “Do you know what knocking is?”

“Someone woke up on the wrong side of the bed,” she said, stifling a giggle.

I gave her a look, and she aimed her eyes at the tent instead. “What have you pitched there?”

“Give me a break,” I said, tucking it into the waistband of my underwear.

“I just want to give you a good morning hug,” she said.

“Sure, but let me get dressed first.”

“Okay… Mom just left. She made pancakes for us,” she said, beaming.

The heavenly scent wafted into my room. It was a sweet smell that I had missed—Mom’s culinary arts. “I can smell them,” I said. “Now be a good sister and bring me some clothes.”

“Okay,” she replied happily. She spun around, the hem of her nightgown lifting and revealing a glimpse of her smooth, round buttocks. With a slight bend at the waist, she reached into the wardrobe to search for an outfit. I couldn't resist stealing glances at how her figure had evolved since a year ago. Her curves were more defined and alluring, causing my heart to race and my cheeks to flush with heat. As she turned to face me, I couldn't help but notice the subtle sway of her larger breasts. The years had been kind to her curves, and it was safe to say, she had become a well-endowed young woman.

“Meet you downstairs, sleepyhead,” she said, closing the door and scurrying off.

“Sure thing.” It was one or the other, sleepyhead or Link. Neither one bothered me.

I put on my clothes and headed downstairs. She stood at the entrance to the kitchen and looked up at me. Standing at five foot four, she opened her arms. “Good morning hug, remember?”

I let her fall into my arms, holding her close. At six feet tall, I was the perfect height to embrace her. “I’ve missed you,” she said, her voice muffled in my chest.

“I’ve missed you too,” I said. As I held her, I felt her heartbeat, but then I also noticed the curves of her breasts gently pressing against my chest. I realized she was still dressed in her tight nightgown.

“Finally, we can spend some time together,” she said, breaking the hug, a smile spreading across her lips.

“Seriously… how long have you had that nightgown?”

She glanced down at her chest, and then her eyes met mine again. “What’s wrong with it?”

“You’ve grown… You’re not a kid anymore.”

She waved her hand dismissively. “It’s snug, comfy, and fits me perfectly.”

“Whatever,” I said, just glad to be with her. “You can at least wear a bra.”

“But then it wouldn’t fit right,” she pointed out matter-of-factly.

“Fine,” I yielded, though I couldn’t help glancing at her from time to time.

We ate breakfast and then played some Switch together. Eventually, we ended up outside on the terrace, sipping some strawberry juice and talking about life. Suddenly she asked me, “What do you think of sex toys?”

“They’re for girls,” I said, not sure where this direction would be heading. I also clearly remembered our mother confronting her earlier this morning. A memory that made my cock stir awkwardly.

“What do you use?” she asked bluntly.

“My hands,” I said.

“Right, but don’t you get bored with your hands?” she asked.

“Yes, but I have no other options,” I replied.

“How often do you touch yourself?” she asked right out of the blue.

“Uhm,” I said and was a bit caught off guard by her question. “Sometimes … once or twice.”

“In a week?” she pressed, tilting her head with that curious glint in her eye.

“No,” I mumbled, my face heating up.

“How does it feel?” she asked with not a hint of playfulness but plenty of curiosity.

“I think it feels similar for you.”

“I think it feels nice,” she said.

“How many times a day do you do it?” I asked her. It just rolled out of my tongue even if I felt a bit awkward by this conversation.

“A couple of times a day, depending if Mom is home,” she said, which was followed by silence. “When you do it, do you watch porn?”

“Sometimes,” I admitted and started feeling my armpits growing sweaty despite the cool drink in front of me. “And you?”

“I like porn … especially lesbian porn, but I don’t like the excessive moaning.”

I chuckled and scratched my neck. “Neither do I.”

“I also watch some fantasy porn, but I don’t get off to it. I just like to watch it.”

“Sure.”

“Why do I get the feeling you aren’t comfortable talking about this?”

“We’re siblings,” I reminded her.

“So? Mom and I are quite open about things. She even offered me blowjob lessons for when I’d find a boyfriend … if that day ever comes.”

I laid my hand over hers. “Luna, eventually you will find someone special.”

“That’s nice of you,” she said.

I realized I’d glossed over a part of her sentence. “She offered you blowjob lessons?”

“Uh-huh,” she said and nodded. “Why wouldn’t she? She wants what’s best for us.”

“Huh …”

“We’re just talking,” she reminded me.

“Sure … But we haven’t had this discussion before.”

“Till I found out how good masturbating feels like,” she said.

I shifted uncomfortably in my seat, not sure how to respond. Part of me wanted to change the subject, but another part was intrigued by Luna's openness. "I guess I'm just not used to talking about this stuff with you," I admitted. "But you're right, we're just talking. There's nothing wrong with that."

Luna smiled, seeming pleased that I was opening up. "Exactly. I feel like I can tell you anything. You've always been there for me."

Her words touched me because I knew it was true. I’d stood up for her when she was bullied. There were times when I didn’t go out because Luna was sad. She will always have a special place in my heart. "Of course. You're my big sister. I'll always be here for you."

We left the masturbation subject behind, went inside to play some Switch and then we ate dinner.

After we’d eaten, it started getting darker, perfect timing for a movie. She brought some cookies and milk for us both, along with a blanket for herself. "You sure you don’t want a comfy blanket?" she asked.

"I'm fine," I said.

She selected a film and settled down under the blanket. I quickly realized it was a romantic movie. It was enjoyable, even if it wasn’t one of my favorite genres. We exchanged occasional glances, silently checking in on each other’s thoughts about the movie.

The way she kept her hands under the blanket made me wonder if she was touching herself. I shook my head, unsure why my thoughts were drifting that way. At least she was wearing a regular top now and not a sexy, body-hugging fantasy dress or a skimpy nightgown.

As the film became more intimate, she inched closer to me. Eventually, she leaned her head onto my shoulder. It reminded me of how it felt to cuddle with someone close, making me suddenly aware of Luna’s skin against mine.

When the kissing scene started, she looked at me, and I saw something in her eyes I hadn’t seen before—a longing for intimacy.

The sex scene that followed was tame compared to porn, but watching it with my sister made it feel a lot more intense. Luna’s eyes widened slightly as the guy made love to the woman in the missionary position under the sheets. I glanced at the blanket and noticed my sister’s hand moving toward her crotch. She drew a slow circle but stopped when the scene was over.

After the movie ended, she was still cuddled up to me. With a soft smile on her face, she looked up and asked, "What did you think?"

"It was alright," I said with a shrug.

"How does kissing feel?" she asked out of the blue.

“I don't know, never had one,” I admitted, my voice barely above a whisper, feeling a flush creep up my neck.

“Oh... Do you think we could try?” she asked, her eyes wide with that mix of curiosity and mischief.

"Sure," I said. I didn’t think much of it. It was just a kiss. It couldn’t hurt, especially if it would help her feel better about herself. I leaned in and pressed my lips to hers. I felt a spark right away, a spark of something forbidden that seemed to be brewing between us.

When I pulled away, she beamed. "That was nice... but it wasn’t like they did it in the movie."

"You mean a French kiss?" I asked.

She nodded eagerly, her blue eyes sparkling behind her contacts. She grabbed my arm and pleaded, "Please."

"Okay," I said. There was something in her voice that I couldn’t resist. I gently pushed her glossy hair behind her ears. The initial peck had felt surprisingly good, so I wanted to see if there were more sensations and feelings to explore.

I pressed my lips to hers, gently tracing the seam of her lips with my tongue. She was inexperienced, but she responded by parting her lips and letting me in. I started with my hand on her shoulder but then moved it to gently cup her neck, deepening the moment between us. We were fully immersed in the forbidden kiss. My heart raced, my mind screaming to stop, but the thrill was too intense to resist.

Even though this was taboo, I leaned in closer, deepening the kiss. It was something that had been building up for a long time, and I lost myself in the sweet taste of her mouth and the warmth of her body.

When I finally pulled away, a thin string of saliva stretched between our lips. As my heart rate lowered, I was left speechless.

"Wow," Luna whispered, clasping her hands over her heart. "That was amazing."

"It really was," I replied, still stunned. It felt better than any other kiss in my life, and I couldn’t explain why. It was deeper, more intimate, with a touch of forbidden excitement. Part of me knew I should have pulled back, but I didn’t want to. I found myself craving more—more of that intense intimacy. It was the first kiss of my life.

"Thank you," she said softly, looking at me with the same expression she had when I stood up for her bullies or comforted her when she was upset. It meant the world to me to be able to do something for her.

"You’re welcome."

"I’ve never felt anything like that... No wonder they always romanticize kissing."

"Yeah," I said, still at a loss for words. A quiet moment lingered between us, just on the edge of becoming awkward as her cheeks turned pink.

“Do you remember earlier when we talked about masturbating?”

“I do,” I said and narrowed my eyes on her, guessing where this was going.

“I became a bit turned on by the film,” she started. “Do you think we could masturbate together?”

I blinked at her. I thought it was brave of her to ask me even if I started to predict where this was heading. “It starts with talking about it, and then a kiss and the next logical step would be to go there.”

She shrugged. “Yeah, so?”

“Where are we going with this?”

“I dunno,” she said. “I can tell that the kiss felt nice for you too.”

“It sure did,” I said.

“I’m just curious how it looks when a guy masturbates. You’ve probably seen a girl already.”

“Girls have different methods though. It’s pretty straightforward to guys.”

“You don’t want to know how I do it?” she asked.

It sure was tempting, and if the kiss felt that good, I wondered how masturbating with her would feel like. “Fine,” I said. “Where should we go?”

“To my bedroom,” she said. She swung her feet off the bed, and she eagerly helped me to my feet.

“When does Mom come home?” I asked her.

“An hour,” she said and had everything under control.

As we entered Luna's bedroom, my heart was racing. Luna closed the door behind us and turned to face me, her cheeks flushed with excitement. “Do we undress?”

“Unless you masturbate with your clothes on,” I teased her.

I took off my shirt, and her eyes swept over me before she pulled the top over her head. It felt like slow motion when she reached behind her back and unhooked her bra, freeing her boobs in front of my eyes. They bounced and jiggled till they found equilibrium. To me, they looked perfect. Not too big, so it would take ages to explore them, but not too small so there was nothing to hold onto. They were two perfect mounds topped with a sweet, pert berry at each peak, and her pink nipples blended well with the creamy white color of her breasts.

“Uhm, do you like them?” she asked while twirling her hair on her finger.

“They are gorgeous,” I said when I realized I’d been staring for longer than necessary. I knew women like attention but there was a limit before it turned creepy.

She beamed. “I was a bit insecure about them since they were small for so long, but now all of a sudden they started growing.”

“You make it sound as if it were a curse.”

“No … As long as they don’t end up like melons,” she said with a titter.

We peeled off the rest of our clothes. Once she reached her panties, I noticed a little wet patch at the center. I gently lowered my shorts, freeing my cock which bobbed up and down. Her eyes widened, and she froze with her fingers on her panties. She was right about to slide them down but stopped. A part of me felt it hard to believe we were doing this.

“Wow … can that fit in a kitty?”

“As long as you’re aroused,” I said.

“Can I touch it?”

“Sure,” I said.

She reached for it and curled her hand around it, gently stroking me up and down. She burst out giggling. “Did you slip a bone inside?”

“Very funny,” I said. “Are we going to masturbate or tell jokes?”

“I find it funny that you’re now so horny that you can’t suppress it.”

“Yeah, it didn’t feel as odd as I thought it would,” I admitted. I tugged at her panties. “Come on, are you going to keep your little pet caged in for the rest of the day?”

She bent over and slid her panties to her ankles, kicking them aside. I caught a brief glimpse of her pink, wet folds before she jumped onto the bed with her back against the wall. She patted the spot next to her. The last time I sat there was years ago when we’d played DS together.

I joined her, glancing between her legs at her pink womanhood. I couldn’t spot any stubbles on her clean flesh. “Do you always shave?”

“Every other day … But sometimes, I like to grow hairy just to see how it looks.”

“Kind of like me … Now show me how you masturbate,” I prompted her, wondering if she had any specific ways.

“So, first I usually wet my fingers,” she showed me, licking her fingers with her tongue, “and then I draw a circle on top of my kitty like this,” she said and gently massaged the top of her folds with her glistening wet fingers. I couldn't help but feel like I was witnessing a private art exhibit. It was both forbidden and intriguing to see my quirky big sister pleasuring herself in front of me. “I also rub the clit now and then and slide a finger inside me.”

“Why aren’t you getting going?” she asked. “I want to come when you come.”

“Good point,” I said, curling my right hand around my cock and stroking myself. I watched intently as Luna demonstrated her technique, her fingers moving in slow circles over her most sensitive areas. The sight of her pleasuring herself was incredibly arousing.

"That feels good?" I asked, my voice husky.

She nodded, biting her lip. "Mhm. What about you? Show me how you do it."

I gripped my cock more firmly, sliding my hand up and down. "Like this," I said. "Varying the speed and pressure."

“It looks so dry,” she said. “Don’t you ever use lotion?”

“To be honest, I haven’t masturbated in a long time, but when I did, I did use lotion.”

“Can I get some for you?” she asked, stopping with her hand in her honeypot.

“It’s fine sis … this feels quite intense already.”

“I feel it too,” she said. “It just feels so good, so I don’t want to stop.”

“We’re on the same page,” I said.

“Do you want to touch me too?” she suggested. “Maybe not as exciting for you since you already touched a girl.”

“It’s always exciting to touch another girl,” I said and reached into her private area till I made contact with her flesh. She was soaked and her folds were as smooth as velvet. It was quite pleasant to touch her, feeling her wet heat spilling over my fingers. As she spread her legs, her pink, plump folds glistened in the dim light of the bedroom. Her lips were slightly swollen and slick with arousal, a clear sign that she was horny.

I pulled back and stroked myself with the same hand I had touched her with. It was slightly wet but enough lubricants for now. “Do you need some spit?” she offered me.

“Sure,” I said. I didn’t want to take my hand away from my cock. It just felt so good. She held her hair back as she leaned forward and carefully spat in my hand. I wrapped my hand, covered with her juices and spit, around my cock. It felt way better.

We moved our hands in unison, Luna's fingers circling her clit while I stroked my shaft. The room filled with the soft sounds of our breathing and occasional quiet moans. I found it hard to believe we were doing this, but at the same time, it felt too good to abort. Luna's cheeks were flushed pink, her blue eyes half-lidded with pleasure behind her glasses.

"This feels so much better than doing it alone," she whispered.

I nodded in agreement, too caught up in the sensations to speak. My eyes roamed over her body—the gentle curves of her breasts that jiggled and the glistening pink between her thighs. She was beautiful in a way I hadn’t noticed before.

Luna's movements became more frantic, her hips lifting slightly off the bed. "I think I'm getting close," she panted.

Watching her pleasure herself pushed me closer to the edge. My hand moved faster, pre-cum leaking from the tip and easing the glide of my fingers. The familiar tension built in my lower abdomen.

"Me too," I groaned.

Luna's back arched off the bed, her thighs trembling. "Oh," she moaned, her words cut off by a sharp gasp. Her body tensed, then shuddered as waves of pleasure washed over her. Watching my sister come pushed me over the edge.

My balls tightened as the pressure built to an unbearable intensity. Just as I was about to climax, Luna sat up suddenly, leaning towards me. The shift caught me off guard. My hips jerked involuntarily as I started to cum, and before I could stop it, thick ropes of semen spurted onto Luna's chest and breasts.

"Oh!" Luna exclaimed in surprise, looking down at the pearly streaks across her skin.

I aimed my cock back at myself. The third spurt hit my chest and then the rest spilled over my fingers as I slowly resorted to stroking myself. “Gosh,” I mumbled. It must have been the best masturbation in my life.

My big sister caught her breath as she studied my semen. “Is it normal to shoot so much?” she asked me.

“Depends,” I said. “Not abnormal, but this was a bit more than usual.”

She touched it with her finger and tried tasting it. “It’s very filling.”

“Yeah,” I said. We exchanged glances, and I saw how a light sheen of sweat covered her body along with my semen that dribbled down her curves, leaving a pearly trail behind.

But instead of pulling away, Luna's eyes locked onto mine with that same curious spark from earlier. She wiped a streak of cum from her breast and smeared it playfully over her nipple, her breath still coming in soft pants. "That was... intense," she murmured, her voice husky. "But I don't think we're done yet."

I swallowed hard, my cock twitching back to life despite the aftershocks. "What do you mean?"

She scooted closer, her hand trailing down my thigh, fingers brushing my softening length. "I mean... I've always wondered what it feels like for real. With someone. With you." Her cheeks flushed deeper, but there was no hesitation now—just that bold, quirky openness that had always defined her.

My heart hammered. Part of me knew this crossed every line, but the heat in her gaze, the way her body still trembled from her orgasm... it drowned out the warnings. "Luna... are you sure?"

She nodded, leaning in to kiss me again, her lips tasting of salt and sweetness. "More than sure. Show me, little bro."

"Wait," she said suddenly, pulling back a little as our bodies pressed closer, her hand still wrapped loosely around me. "Do we need a condom? Like, for safety?"

"For safety, yeah," I said, my voice thick, trying to think straight through the haze of want.

"But we don't have one," she said, biting her lip, her fingers tracing idle circles on my thigh.

"Let me go and get one," I offered, already half-sitting up, though the idea of leaving her warmth felt impossible.

"But Mom will be back by then," she said, glancing at the clock on her nightstand. Her eyes lit up with that mischievous glint again. "Let's see if Mom has one."

Before I could protest, she was off the bed, naked and unselfconscious, padding out of the room with a quick wink over her shoulder. I sat there, heart pounding, cock still hard and aching, listening to her soft footsteps down the hall. It felt like forever, but then she was back, a foil packet clutched triumphantly in her hand.

"Here," she said, climbing onto the bed and straddling my lap, her wet heat brushing against my thigh as she tore it open with her teeth. Her fingers were a little clumsy at first, fumbling with the condom, but she giggled softly, focusing like it was a puzzle from one of our old video games. "Hold still, sleepyhead," she teased, rolling it down my length with careful strokes, her touch sending fresh sparks through me. "There... all set."

I didn't need more convincing. I guided her back onto the pillows, her legs parting instinctively as I settled between them. The tip of my cock nudged against her slick entrance, and she gasped, her hands gripping my shoulders. "Go slow, okay? I've... well, you know, toys, but this is different."

"Slow," I promised, echoing her from earlier, pressing forward inch by inch. She was tight, warm, enveloping me like velvet fire, her walls fluttering around me as she adjusted. "Oh... Chase... that feels..." She trailed off into a moan, her nails digging in just enough to sting.

"Feels what?" I whispered, buried halfway, holding still to let her breathe.

"Full... so full and good," she panted, rocking her hips experimentally, pulling me deeper. "Like, better than I imagined. Keep going?"

I nodded, sinking the rest of the way in with a groan that matched hers. It felt like coming home and breaking every rule at once—raw and electric, her body yielding to mine in ways I'd only fantasized about. We started slow, testing, my thrusts shallow and deliberate, her hips rising to meet me each time. "Like this?" I asked, voice rough, watching her face for every flicker—her eyes half-closed, lips parted.

"Mmm, yeah... just like that," she murmured, one hand sliding up to tangle in my hair, pulling me down for a messy kiss. Our tongues tangled as I picked up the pace, the bed creaking softly under us, her breasts bouncing with each gentle roll of my hips. Still glistening with my earlier release, they brushed against my chest, and I broke the kiss to lean down, capturing a nipple in my mouth, sucking lightly, tasting the salt of us mixed together.

She arched, a breathy laugh escaping her. "Oh god, that tickles but... don't stop. Feels amazing." Her legs wrapped around my waist, heels digging into my back, urging me deeper. "Faster now? I think I can take it."

"You sure?" I checked, lifting my head, our foreheads touching as I hovered, buried to the hilt.

"Uh-huh," she nodded, her blue eyes locking on mine, sparkling with that same trust from when we'd sneak games late at night. "I want to feel all of you. Make me... you know."

I did, shifting my angle just a bit, thrusting harder now, the slap of skin on skin filling the room alongside her quiet moans. "Like this, sis?" I gasped, one hand bracing beside her head, the other sliding between us to circle her clit with my thumb, mirroring what she'd shown me earlier.

"Yes! Right there," she cried out, her body tightening around me, hips bucking up wildly. "Chase, it's... building again. You're gonna make me come."

The words undid me, my rhythm faltering as the pressure coiled low in my gut. "Me too... so close." Sweat slicked our skin, her curves pressing into me, every slide and grind heightened by the forbidden thrill—the fact that it was her, my big sister, whispering my name like a secret.

Her walls clenched first, hard and rhythmic, pulling me under as she shattered. "Oh... Chase! Yes!" she gasped, trembling beneath me, her fingers clutching my back like she'd never let go.

It tipped me over—deep inside her, pulsing hot and endless against the thin barrier, wave after wave until I collapsed forward, spent and shaking. We stayed like that, tangled and breathless, her fingers tracing lazy patterns on my back as our heartbeats synced.

"That... was better than any toy," she whispered finally, a sleepy smile tugging at her lips, her voice soft with wonder.

I chuckled, pressing a kiss to her forehead. "Yeah. Way better."

Suddenly, I started thinking of Mom. I started getting paranoid in case she would find us here, both of us butt naked and spent. “When is Mom back?”

“She’ll be here any minute,” Luna said. She looked a bit disappointed as if she wanted to pillow talk.

“You have to clean yourself,” I said. “We can’t let her find out we did this.”

“Alright … I’ll go to the bathroom first,” she said but hesitated, looking at me. “It felt really nice.”

I broke out in a smile. “I agree,” I said. “It did feel nice.”
