I stretched out my arms and legs as I slowly opened my eyes, realizing I was back in my old bedroom. Now that it was summer, I was staying with my family—my little sister and my mom. I’d missed them both and needed a serious break from college life.

My little sister, Hailey, was nineteen years old and a gymnast. She used to compete when she was younger, but that stopped once her breasts started to develop, which made her self-conscious. Big boobs were usually an asset, but not if you were serious about sports.

Our mother was well-endowed too—she couldn’t go anywhere without turning heads. She’d mentioned it could be exhausting, especially given her profession. She was a therapist, so she mostly worked with female clients. Even in conservative blouses, her bust was noticeable and made her stand out in a crowd of other women. Guys couldn’t help but look. I couldn’t blame them; I understood the appeal.

I reached for my phone on the nightstand and noticed a new message. Lazily, I rubbed my eyes and unlocked the phone. Then my eyes widened—I’d received a nude photo of someone incredibly attractive. I’d never seen such an athletic, toned body, yet the breasts, though round and full, still looked completely natural on her. She was standing in a bathroom with her legs crossed, so I couldn’t see her peach but plenty of thighs. I hardened in an instant, pitching a giant tent in the middle of the bed. I started having sexual fantasies about her, wondering what her womanhood looked like.

“Wow,” I murmured, wondering who my secret admirer might be. Or maybe … It was just a mistake. My gaze drifted farther up the photo. The blonde hair was mesmerizing, but half the face was cut off, leaving me a bit disappointed.

Curious, I glanced at the number and saw the name next to it: Little Sis. My heart rate shot up, practically hammering out of my chest. I quickly hit the power button to put the phone to sleep.

“What the hell?” I muttered to myself, staring blankly at the ceiling.

I couldn’t believe what I’d just seen. My little sister, Hailey, had sent me a nude photo? It had to be a mistake. Maybe she’d meant to send it to someone else and accidentally chose me instead. But that theory went out the window when I saw the message: Are you awake, bro?

My mind was reeling. I tried to push the image out of my head, but it was seared into my brain. Those curves, that athletic body I’d always admired from afar… No, I couldn’t think about Hailey that way. It was wrong.

I heard movement in the hallway outside my room. Footsteps approached and there was a soft knock at the door. “Jakey, are you awake?” she asked, her voice as sweet as honey.

I looked awkwardly at the pitched tent that my sister had caused, and I hurriedly tucked my erection into the waistband. She slowly opened the door and peeked inside. “Are you still in bed?”

“Just woke up,” I said, looking at her. She was gorgeous—easily an eleven on a ten scale. She wore tight, pink leggings and a matching sports top, her legendary breasts straining against the fabric. To her, they’d always been a curse; to everyone else, they were a blessing.

“Good morning,” she said, her lips sliding up in a smile. “Mom left a little while ago, but she made breakfast for us. Ready to hit the gym later?”

“I’m ready. I’ll be down in a minute,” I told her.

“Want me to pick out your clothes?”

“Sure,” I said, swinging my legs over the side of the bed.

Hailey smiled and bounced over to my dresser, her chest swaying with each step. I averted my eyes, forcing myself to shove away any inappropriate thoughts. She hummed softly as she rummaged through my clothes. While standing bent at the waist, she showed off her butt. Those leggings rode up her ass crack as they would split in two.

She whirled around, and my eyes quickly bounced to hers, but she grinned as if she’d caught me looking. “How about these?” she asked, holding up a pair of gym shorts and a fitted T-shirt.

“Perfect,” I said, my voice sounding slightly strained.

As she leaned forward to place them next to me, I caught a glimpse of her cleavage.

“Is something wrong?” she asked, twirling a lock of hair around her finger.

“Did you maybe … accidentally send something to the wrong person a minute ago?”

“No … I sent you a good morning message with a photo of my outfit.”

“You better check again.”

She froze, her eyes widening, cheeks turning a shade of pink that made them look like strawberries on a bright summer day. She grabbed her phone, and that pink deepened to red, ripe apples. “Oh God, please kill me now.”

“It’s fine,” I told her, not wanting her to feel bad. “Accidents happen. I’ll just delete it.”

“I swear, I didn’t mean to,” she stammered, her hands trembling a bit.

“Sis, it’s okay,” I said gently. “Who were you even sending it to?”

“I … wasn’t supposed to send it at all,” she said. “I was trying to send you a photo of my outfit.”

“Got it,” I said, and that made much more sense. I showed her my phone to confirm I’d deleted it, but I knew what I’d seen wouldn’t be easy to forget. Her nude would probably linger in my mind the rest of the day, maybe longer.

“Thank you,” she murmured.

“Give me a minute to get dressed.”

She nodded and headed outside. It wasn’t as awkward as I’d imagined it to be. But what surprised me was that I still had an erection. She was prettier nude than I thought. She was way more beautiful than any other girl I’d been with in the past. It was the first time I had to admit she was sexy.

(below could write as a montage)

We finished eating and cleaned up the kitchen together. And after we’d packed our bags, Hailey turned to me with a mischievous glint in her eye.

“Race you to the gym?” she challenged.

I grinned. “You’re on, little sis.”

We took off running, laughing. We must have looked like idiots as we two grown adults ran across the streets. It reminded me of when we were young and carefree. I always felt that way when I was with her.

As we neared the gym, Hailey glanced at me with a playful smirk. Since I didn’t jog as fast as I could, she was right next to me. Her foot caught on an uneven part of the sidewalk and she started to stumble. Without thinking, I reached out and caught her around the waist, pulling her against me to steady her.

For a moment we stood there, bodies pressed together, both breathing heavily from the run. I could feel the softness of her breasts against my chest, the curve of her waist under my hands. Our eyes met and something electric passed between us.

Hailey’s cheeks flushed pink as she stepped back. “Thanks,” she said softly. “I guess I should watch where I’m going.”

“It’s fine,” I said, trying to think of something else to say. “You almost won.”

She chuckled. “I have a feeling you let me.”

“Nuh-uh,” I teased.

“Uh-huh,” she shot back, blowing me a raspberry. “One day, I’ll beat you fair and square.”

“In your dreams,” I said, and she gave my shoulder a playful punch as we walked into the gym.

This was one of the few gyms with a gymnastics facility, and it wasn’t far from where we lived. My sister had trained here throughout her childhood and teens. These days, she still did some weightlifting, but she mainly liked to do gymnastics, stretches, and a bit of yoga.

“See you,” she said as we split up for the locker rooms.

“Don’t spend an hour in front of the mirror,” I teased.

She rolled her eyes but smiled a little behind it.

I dumped my bag in the locker, and we met outside at the same time. She looked great in her leggings and sports top, though I always thought she looked her best in her leotard. I probably shouldn’t think that way, but it was difficult not to, especially after I’d seen her nude. I could delete that photo from the phone, but I knew I couldn’t delete it from my mind.

*****

After we’d been to the gym, we returned home. I let her take a shower; she had to get ready for her gymnastics class soon, and she wasn’t a fan of showering in the gym. For the summer, Hailey taught younger girls gymnastics. She enjoyed it, but she’d still told me she’d rather be competing.

As I sat there waiting, I couldn’t help but feel more aroused—not because of any gym girl, but because of my little sister. I’d seen her do gymnastics countless times before, but today felt different. I thought it had something to do with the nude photo I’d seen of her earlier.

She finally finished her shower and took her time getting ready. I wondered why she was taking so long, considering she’d probably shower again after her class. That was something I’d never understand about girls: several showers and baths a day, a hundred different soaps, shampoos and makeups, and wardrobes and drawers filled with clothes.

Eventually, she came downstairs, dressed in a tight, pink, glittery leotard. Her hair was in a neat bun, and she’d applied a little makeup, looking absolutely gorgeous and smelling faintly of roses.

“Ready to go?” I asked.

She nodded. “I’m ready.”

She hopped into the car, and I drove her there. “So, how’s it going over there?” I asked. “Are you having fun teaching?”

“Yeah… but I’d rather be competing,” she said with a sigh I knew well.

“There are plenty of opportunities out there,” I reminded her, hoping to cheer her up.

“I know, but it was my lifelong dream,” she said wistfully.

“We can talk about it later if you want,” I offered. We’d talked about it before, but I always wanted to show her my support. It meant a lot to me to see her smile.

“You’re sweet,” she said. “But I feel cursed and blessed at the same time.”

“At the same time?” I asked, raising an eyebrow as we drove along. “How does that work?”

“Well, cursed because of my boobs,” she said and gave them a playful lift with her hands. “And blessed because I have you and Mom.”

“Oh, I see,” I said, my lips curving in a smile. “Your boobs aren’t a curse … They’re a blessing too.”

“But they kind of punctured my dream bubble.”

“There are plenty of other things to do in life too,” I told her.

“Maybe, you’re right,” she said. “But I still think they’re too big, and I think they’re still growing on top of it. I’m not sure about the shapes of them … By the way,” she asked sneakily, looking unsurely at me. “Since you saw them earlier, do you think they’re pretty?”

She caught me a bit off guard. When I saw the photo, they were the most beautiful breasts that I’d ever seen. “Uhm … “

“It’s just you and me here,” she said.

“They’re perfect,” I told her sincerely. “I haven’t seen such beautiful breasts in my life.”

“Really?” she asked, her eyes lighting up.

“Yeah, I’m serious. It’s just… since you’re my sister, I probably shouldn’t be saying that.”

“Why not?” she asked.

I looked at her, trying to gauge if she was joking or not. “Come on, do the math.”

“You do the math,” she retorted, laughing. “I’m not a smartass like you.”

We both chuckled. I wanted to steer the conversation in another direction, but first, I had to tell her, “It’s your character that I love most about you. Everything else is just a bonus.”

“Thank you,” she said softly, and I could tell it meant the world to her.

When we arrived, I pulled up to the curb and dropped her off. “Mom’s driving me home later,” she mentioned.

“I know,” I said. “Have fun.”

“You too,” she replied.

*****

As I got back home, the conversation lingered in my mind. She’d never asked me such an explicit question before, wondering what I thought of her boobs. They were beautiful. I couldn’t lie, but I wasn’t sure why she was so insecure about them. I get it that she had a dream of competing as a gymnast, but at the same time, any man would drool over them … including her older brother. I shook my head. I wasn’t sure why I was thinking about this.

Mom wouldn’t be back till an hour, so I tried to get some fresh air. I went outside to the terrace and slumped down on the sofa. I started thinking more about what had happened, and I found it hard to believe that she’d accidentally sent me that photo. I’d been with four girls before, and none of us had ever accidentally sent a wrong pic to someone.

I brought out my phone as I sat in the shade. I googled: accidentally sending nudes. I got results mainly from relationship forums. The answers made my armpits a bit sweaty. They all agreed that if a girl or a boy accidentally sent nudes then it was a sign that they had a thing for the person. I scratched my neck, wondering whether it was true or not. I even stumbled upon an incest forum, and there was a girl there asking whether it was a good idea or not to accidentally send nudes to her brother who she’s in love with. They all agreed it was a good first step. I blinked at the text, wondering if my sister had planned it that way. Our conversation in the car sure made it seem so. They’d also mentioned asking what he thought of her looks. “Next time you’re in the bathroom, don’t lock the door and let him walk in on you,” I read the comment. I’d need to be careful later.

*****

Later in the evening Hailey and my mother returned. After we’d eaten dinner together, I headed upstairs. Right when I opened the bathroom, I flinched. My sister sat on top of the toilet seat. Her pussy was covered in shaving gel and she carefully glided the razor over her pussy lips … that looked pink, sweet and absolutely gorgeous.

She looked at me like a deer caught in the headlights. “I’m sorry I forgot to lock.”

“It’s okay,” I said and gently closed the door although I struggled to drag my eyes away from her beautiful slit.

I returned to my bedroom and tried to process what I’d just seen. Now I definitely knew that I would not be able to get her naked body out of my head. As the scene of her nude was seared into my brain, my cock slowly but surely hardened till the head pushed against the zipper. I became so turned on that I badly wanted to masturbate. I promised myself not to think about her … Just someone who looked like her.

After she was done, she knocked on my door. “I’m finished if you want to use the bathroom.”

“Thanks for letting me know,” I said, opening the door.

She stood in the hall, demurely twirling her hair on her finger. “I’m sorry … I’m just used to having the bathroom by myself since you’ve been gone,” she said while she wore a bathrobe. Even if the belt was tied tightly around her robe, it still strained against her bust.

“Don’t worry about it,” I said and gave her a friendly pat on her shoulder. Going inside the bathroom, I locked the door, and I could easily picture her nude on top of the toilet seat. I looked at the shower and debated whether to masturbate or not.

I stepped into the shower, trying to clear my mind of the image of Hailey. But as the warm water cascaded over me, I couldn’t help but replay what I’d just seen—her smooth, glistening skin, the delicate curve of her hips, the soft pink of her most intimate area. My body responded instantly, blood flowing south to my already-hard cock.

I felt both guilt and desire. This was my little sister. I shouldn’t be thinking of her this way. And yet…I couldn’t deny the attraction I felt.

Almost against my will, my hand drifted lower. I closed my eyes, giving in to the fantasy. In my mind, it wasn’t Hailey on the toilet seat anymore, but straddling me, her lithe gymnast’s body moving in perfect rhythm. I imagined her breasts, the ones she was so self-conscious about, pressed against my chest as she rode me.

My breathing quickened as I stroked myself faster. “Hailey,” I whispered, so softly even I could barely hear it over the shower. Five more pumps and my hips bucked. With a stifled groan, I finished, shooting my seed against the wall, dreaming it was my sister’s nude breasts. I drew in a deep breath as my cum washed away down the drain.

*****

The following day, I slowly opened my eyes, emerging from a deep sleep. Yesterday was still fresh in my memory, and I remembered exactly what I did in the shower. It was the first time in my life I’d let my thoughts linger on her that way. The first time I’d ever crossed that line—masturbating to her while she was at the center of my attention. It felt strange, a bit forbidden. She had been acting differently than the last time I’d seen her, and I couldn’t quite figure out why. Maybe I was reading too much into it, or maybe it had just been a coincidence that she’d accidentally sent me a nude, or that she’d forgotten to lock the bathroom door while shaving her privates.

But gosh, she’d looked so beautiful. The way the foam framed her slit, and the way she gently took care of herself. It was so feminine and sexy.

I tried to shake the thoughts from my mind as I reached for my phone. This time, there was also a new message from her, and I felt my heart rate quicken. I opened it to see a photo of her in tight leggings and a sports top along with the message, I sent you the right photo this time. Let me know when you’re awake, followed by a smiley face. I chuckled. I loved her playfulness and the way she managed to smooth over any awkward moment.

Curious, I went back to the forum I’d been reading yesterday. Something about that post had felt strangely familiar, almost suspicious. The writing style sounded just like hers, though I found it hard to believe it could actually be my sister. But when I reread the username, it just became so much more obvious. “HopelessGymnast,” I muttered to myself. It got to be her. Why did she pick such a depressing name? I had a lot of questions during that moment, but I read some of her other posts.

HopelessGymnast: It was a bit embarrassing lol, but his reaction wasn’t bad. He also told me that my boobs were pretty. And he also walked right into me while I was shaving my kitty. He looked at me longer than necessary. He tried to look away, but I definitely noticed, and I’m almost certain his penis got hard.

Bisexualsisters69: That’s awesome, girl. Remember to warm him up for it, and you will taste his hard penis in no time.

HopelessGymnast: Thank you for your support. And she ended it with a heart emoji.

“Jesus Christ … This got to be her,” I said and it fully dawned on me. I read some of her other posts where she mentioned how I would return soon for the summer, and that she had a major crush on me.

I slowly lowered my phone and mulled it over on how to talk to her about this. I felt a bit bad when I read about her dilemma. I wanted to see her smile and feel good, not feel guilty about the feelings she couldn’t suppress. I also read another comment by Bisexualsisters69: Girl, you have to wear something sexy for him. And the photo Hailey had sent me confirmed it.

I swung my feet off the sides of the bed and put on my clothes. I descended the stairs, and when I stepped outside the terrace, I was greeted by the sight of my sister doing the front split on a yoga mat. The hem of her leggings had ridden up her butt crack. I wondered how they made those garments without them splitting in two.

“Good morning,” I said and prepared myself to talk to her.

“Morning,” she replied with a smile. The rising sun made her hair shine and her skin gleam. “When did you start sleeping in so late?”

“It’s summer,” I said with a shrug.

“And? It’s like noon. What if someone kidnapped you?”

“You could have been a good girl and woken me up,” I said with a wink.

“I was there knocking earlier, but you were still out cold,” she said.

“It’s fine, sis, I’m here now.”

She made sandwiches for me, and after we finished them, I decided to talk to her. “Well, there’s something I’d like to talk to you about,” I said.

“What’s that?” she asked, her gaze meeting mine, her expression curious.

“Did you really accidentally send me that photo yesterday?” I asked, holding her gaze.

A light blush spread across her cheeks. “Uhm …”

“It’s okay, take your time. Just know, I’m not here to judge,” I reassured her.

After a moment, she finally admitted, “What makes you think that?”

“I just have a feeling you did it on purpose, maybe to test the waters,” I said.

She hesitated, then nodded slightly. “Uhm, yeah,” she said unsurely.

“Does the username HopelessGymnast mean anything to you?”

Her cheeks flushed deeper red, and I immediately felt a twinge of regret. It wasn’t my intention to embarrass her. “Yes, that’s me,” she admitted, trying to smile back.

“Before we dive into that, though—why the gloomy username? You’re usually so full of life.”

“That’s because you’re here … I don’t feel that way when you’re gone, and you’re always busy with your girlfriends, studies or acting.”

“I see,” I said, nodding. “Mom told me the same thing. But you have to remember that you’re more important to me than any other girl I’ve ever met, and you always will be.”

“Oh … even in terms of a relationship?” she asked, hope flickering in her eyes.

“If we weren’t related, I’d be on my knees for you,” I admitted.

She held onto my gaze, unwilling to let go of the moment. “But can’t we still work things out? I read about siblings being… close like that, uhm, on the same forum.”

“How do you know those stories are even real?”

“I don’t. But we could take things one step at a time … and if it feels uncomfortable, we can just go back to being friends,” she said.

“We’ll always be more than friends. We’re family,” I reminded her. She smiled at me but didn’t say much. “After seeing you shave nude, what was your next step?”

She giggled. “You might think this is silly, but I was going to show you this picture.” She held up a photo that Mom had taken of us when we were kids—I must have been around ten, and Hailey about eight. We were kissing each other on the lips. “I was going to say, ‘Look how cute we were… maybe we should recreate it.’”

I couldn’t help but smile. “Yeah… that’s creative.”

She looked at me seriously. “Even if you hadn’t found out about ‘HopelessGymnast,’ do you think you still would’ve kissed me?”

“Without a doubt,” I said, meeting her gaze.

She brightened. “Do you think… we could do it now? I haven’t kissed anyone since.”

“Okay,” I said softly. “We can try.”

Hailey’s face lit up. She inched closer to me on the sofa, our thighs now pressed together. I could feel the warmth of her body through her thin leggings.

Slowly, I cupped her face with my hand, her skin so soft. I leaned in, tilting my head slightly. Our lips met gently at first, just a brush. But it was powerful and felt unbelievably good. It wasn’t just the internal sensations, but also the sensation of her soft lips against mine. Mom hadn’t only blessed her with big boobs but divine skin as well.

“That was nice,” Hailey said, her eyes sparkling. “But you didn’t do it like they do in the movies.”

“You mean French kiss?”

She nodded eagerly.

“Alright,” I said.

“Is it difficult?”

“No, I’ll guide you through it.” I leaned in again, this time parting my lips slightly as they met hers. Gently, I ran my tongue along her bottom lip, requesting entry. She responded eagerly, opening her mouth to me. Our tongues met, caressed each other and then swirled together.

Hailey let out a small moan as I deepened the kiss, my hand moving to cradle the back of her head. Her fingers gripped my shirt, pulling me closer. The taste of her, the softness of her lips and the warmth of her body pressed against mine—it was intoxicating.

After what felt like both an eternity and not nearly long enough, we slowly pulled apart. Hailey’s cheeks were flushed, her eyes bright with excitement, and I was surprised. It was the best kiss of my life.

“Wow,” she breathed. “That was…”

“Amazing,” I agreed, feeling a bit dazed myself.

“Can we do it again maybe another time?” she asked hopefully.

“Sure,” I said and wanted to delve deeper into it. We both just sat there, flustered. We started looking more like two teens in love rather than two siblings, but I didn’t mind.

“So,” she said, poking me playfully in the chest. “Say something.”

“I’m just … a little caught off guard, that’s all.”

“Yeah, me too. Did you find it weird?”

“No, actually, it felt really nice.”

“I’m glad,” she said softly. “I didn’t want to make you uncomfortable, just in case … you didn’t want to kiss me.”

“No, it’s not that at all. I just wasn’t expecting it,” I said, meeting her gaze and feeling a spark between us, knowing this could be the beginning of something deeper. “So … how long have you felt this way?”

“Since I hit puberty, really—when I started noticing boys,” she admitted. “You’ve always been so kind to me, but I never thought you’d actually feel the same. At first, it was just a fantasy, you know, something impossible. Then it just kept growing. I remember reading about Cleopatra and Ptolemy … If it worked for them, maybe it could for us.”

“You’re brave to admit that,” I told her, touched by her honesty.

“Thanks,” she said with a shy smile.

“Why not ‘HopefulGymnast’ instead?” I teased, finally letting a grin breakthrough, and she laughed.

“That’s just how I feel sometimes. I’m in love with my brother, my chest kind of derailed my dreams, and I’m not sure what’s next. I enjoy teaching gymnastics, but I want something more. I just don’t know what yet.”

“I’ve told you before—there are so many options,” I said. “Why not try making gymnastics tutorials? You’d probably get a huge following.”

“Maybe from other girls,” she said, smiling. “But the guys would probably just watch for … these.” She cupped her breasts and lifted them gently.

“That’s probably true,” I admitted, grinning. “But hey, it’s something you might just have to live with.”

“Mom said the same thing. I don’t mind you looking, though.”

“Well,” I said honestly, “they are pretty.”

She twirled her hair on her finger. “Do you want to see them?”

I felt my breath catch in my throat. Her breasts were two treasures that I had also fantasized about. “Well, ever since they started growing, I’ve been thinking about them too.”

“I’ll let you touch them if you want,” she offered.

“Are you sure?” I asked, my voice low and husky.

Hailey nodded, her eyes locked on mine. “I want you to see them,” she whispered.

That sure as hell turned me on. “Let me,” I said and couldn’t resist. Slowly, she reached for the hem of her sports top. I watched, mesmerized, as she pulled it up and over her head. Her breasts spilled free, full and round, with perfect pink nipples that were already hardening in the cool morning air.

“Wow … they’re beautiful,” I said in a lowered voice, unable to take my eyes off them. “You’re so gorgeous, Hailey.”

She blushed, a shy smile playing on her lips. “They’re getting cold,” she said playfully.

My hand trembled slightly as I reached out, cupping one of my sister’s breasts gently. It was soft and warm, filling my palm perfectly. Hailey let out a quiet gasp as I ran my thumb over her nipple.

“Wow,” I said, my voice thick with desire.

She glanced between my shorts, noticing the effect she had on me. It was impossible not to notice as my bulge just grew thicker and thicker. “What’s happening down there?” she asked playfully.

“I think you’re old enough to know that.”

“Is it because of me?”

“I think you know the answer to that question too.”

“You know when I mentioned taking a step out of the time?”

“Yeah,” I said, growing really horny.

“Maybe I could give you a blowjob,” she offered.

I wanted to ask her how far we would go, or if we were perhaps taking it too far. But after I kissed her, and I saw how happy she became, I didn’t want to spoil her happiness. I also wanted this, to see how it would feel. “Can anyone see us here?” I asked and looked around.

“No,” she said in a lowered voice. “My friends and I sometimes sunbathe naked here.”

“Alright,” I said and felt my heart rate rising. “Take off my shorts.”

Hailey’s eyes widened with excitement as she reached for the waistband of my shorts. Her fingers trembled slightly as she hooked them under the elastic. I lifted my hips to help her as she slowly pulled them down, along with my boxers. My erection sprang free, standing proudly before her.

“Oh wow,” she breathed, her eyes fixed on my manhood. “Is it supposed to be that big and hard?”

“Size depends, but it has to be hard,” I said, making it feel as if I were giving her sex ed.

“It’s even bigger than I imagined.”

“You’ve imagined it before?” I asked, my voice husky.

She nodded, biting her lower lip. “Many times.” She reached out and wrapped her hand around my shaft. Her touch was forbidden and soft, sending shivers down my back. She began to stroke me slowly, her movements a bit insecure at first.

“Is this okay?” she asked, looking up at me with those innocent, blue eyes.

“It’s perfect,” I reassured her. “Just do what feels good.”

“Okay, I’ll try to suck now.” Hailey leaned forward, her breath hot against my skin. She darted out her tongue, giving my tip an experimental lick. I groaned at the sensation, my hands gripping the sofa cushions. I was surprised that such a gentle flick could feel that good.

Smiling at my reaction, she took me into her forbidden mouth, closing her lips around the head. I had to fight to keep from bucking my hips. “Hmm,” I mouthed, feeling how much more intense this was compared to any other head I’d been given. I wasn’t sure where to look. I wanted to see her lips stretch around my thickness, but at the same time, her boobs hung freely, gently brushing against my thighs. “Can you look me in the eyes?”

She flitted her eyes up to me. She came off the tip, saliva dribbling down the shaft in pearly rivulets. “Am I doing okay?”

“Yeah, you’re doing fine,” I told her, raking my hand through her blonde hair. “You can use your hand a bit more … and spit on it too.”

“Like this?” she asked, spitting on her hand and wrapping it around my shaft. Then she took the tip into her mouth again, sucking sweetly.

“That’s a good girl,” I told her.

Her eyes lit up, and she slid my cock a bit deeper into her mouth till she gagged, her spit covering my base. I couldn’t tear my eyes away from the sight of my little sister pleasuring me. Her cheeks hollowed as she sucked, her lips stretched wide around my girth. Her breasts swayed enticingly with each movement.

My orgasm was building rapidly. I gently reached for her breasts, enjoying the touch. I slid my hand to her neck, cupping it and helping her suck me. I closed my eyes, and it felt as if I were dreaming, but as I heard her slobbering over my erection, I knew it was better than a dream.

“A little bit more … Oh, Hailey, don’t stop,” I told her. I tangled my fingers in Hailey’s silky hair as she bobbed her head up and down my shaft, taking me deeper into her warm, wet mouth with each stroke.

The slurping sounds of her sucking rose along with an occasional gag or two. Hailey moaned around my cock, clearly enjoying this as much as I was. The vibrations sent shivers down my spine.

I could feel myself getting close, and I knew I would finish in her sweet mouth. “Hailey,” I moaned with my eyes closed, “I’m not going to last long.”

She hummed in response, refusing to take my cock out of her mouth, and I felt my muscles tensing.

“I’m going to—” I started to warn her, but she just looked up at me with those big blue eyes and nodded slightly.

That one glance was all it took. With a muffled groan, I came, spilling my seed into her mouth which splashed against her cheeks. “Wow,” I said, looking down at my sister who continued to slowly suck me. She hadn’t deepthroated me. She hadn’t sucked like an experienced girl either. She had just kept the tip in her mouth, but it was the best sexual experience of my life.
