Skip to content I was chilling on the couch, scrolling through my phone, when a DM suddenly popped up. I opened it, and my eyes went wide. It was a full nude: a girl with natural D-cup breasts, tight, narrow cleavage, rosy pink areolas, and small, short nipples that matched perfectly. My gaze dropped straight to her freshly shaved pussy, pink like cotton candy.
Her waist was narrow, flaring out into hips I desperately wanted to grab. Then my eyes moved up, ready to see the face, and they widened again. It was my little sister.
My heart pounded like a drum, but my cock didn’t soften. It just got harder. She was in the bathroom. I could see her shaving stuff and perfume bottles in the background.
Did she send this on purpose?
It was summer break, and I’d just gotten home from college to spend time with the family. My little sister was a hot gymnast who’d taken a break from competing to coach instead. Her dreams had taken a hit when her tits grew out of nowhere. It got tough to stick landings on the trampoline or nail vaults when everything bounced and jiggled.
She’d always been a little insecure about her chest, and I couldn’t help wondering if this was some kind of test to see how I’d react.
She came down the stairs in a pink leotard that showed off her legs. The fabric rode right up the crack of her ass, and even though it wasn’t low-cut, her boobs strained against it, pushing out a deep line of cleavage.
She whistled as she hopped down the last step with a giggle. “What’re you up to?” she asked, flipping her blonde ponytail over her shoulder. She plopped down next to me and, acting all innocent, inched her hips a little closer. Then she poked my ribs and waved at me.
“Did you maybe send me something by accident earlier?”
She blinked at me for a second, then grabbed her phone. A bright blush exploded across her cheeks and down her neck. “Oh my God, I’m so sorry,” she squeaked. “I meant to send the one in the leotard. The nude was just for me.”
I gave her shoulder a reassuring pat. “Hey, accidents happen. No big deal.”
“Thanks,” she said, looking genuinely relieved. “Promise you won’t tell Mom?”
I leaned in and kissed her forehead. “Promise, sis.”
We chatted about old memories and what we wanted to do over the summer. She didn’t have much planned, besides coaching gymnastics for some teenagers and possibly hanging out with friends.
Eventually, she headed out back to stretch. I still had a semi from that photo, and I had no idea why it wouldn’t go away. “Hey, bro, can you come take some pics so I can check my form?”
“Sure, sis,” I said, getting up. It was hard to look at her like this. She was hot.
I followed her into the yard, phone in hand. She moved into the middle of the grass.
“Ready?” she asked, getting into position.
“Go for it.”
She started with some easy poses, then moved into more complex stretches. When she did a perfect split, my eyes landed right on her ass. The pink fabric of her leotard strained against her body as she extended one leg forward and one back, and her cheeks looked like two perfect globes. The seam seemed to disappear right into the crack, emphasizing her bubbly butt.
“Get this angle,” she said, arching her back.
I circled her, taking photos from different positions with her legs spread wide open. My mind wandered to how flexible she really was, how good she smelled and how open she was. I imagined her legs wrapped around my waist, or spread wide on my bed. In that split position, I could just slide right in …
“Did you get some good ones?” she asked, breaking my erotic dream.
“Yeah,” I said, scrolling through them. “These are amazing. You’re a star, sis.”
She bounced over, standing close to look at my phone. “Wow,” she said. “I look good.”
“You always do.”
She looked up at me. “Do you really think I’m pretty?”
The question hung between us. I knew I should just say something brotherly and move on, but instead I found myself being honest.
“You’re beautiful,” I said, looking her in the eyes. “Or I’d rather say stunning.”
Her eyes welled up. “Even with these?” She cupped her breasts through the leotard.
“Especially these,” I said, looking at them for a sec before looking into her eyes again.
“They ruined everything, though. My whole career. These stupid things are a curse,” she let go of her tits, and they bounced till they found equilibrium.
“They’re not a curse,” I said before I could stop myself. “They’re amazing. Every woman out there’s jealous of you.”
She stared at me for a long moment, then leaned into my chest. I wrapped my arms around her automatically.
“You’re the best,” she murmured against me. “Thank you.”

Later that night, alone in my room, I couldn’t stop thinking about that nude. The curve of her hips, the perfect roundness of her breasts, and also her shaven pussy. Why would she even take a picture like that? It didn’t make any sense, and I doubted it was an accident.
I opened my laptop and typed, Why would my sister accidentally send me a nude?
Most results were porn sites, but I found a forum called Family Secrets that seemed different. I clicked through and found dozens of threads about family love, but one caught my eye, How to hint to your brother that you want him.
My finger hovered over the link. I shouldn’t click it. But I did.
The thread was full of girls talking about their brothers. One wrote, I ‘accidentally’ sent him a nude, but I’m not sure about his reaction. He seemed kinda caught off guard by it, even if he told me I was pretty afterward.
Another replied, Try letting him walk in on you. I did that with my brother, and now we’re together.
I felt myself getting hard as I read more posts. Girls talking about seducing their brothers, brothers admitting they wanted their sisters. It was wrong, but my cock didn’t care.
The next few days were torture. I couldn’t look at her without remembering that photo. I tried avoiding her, but in a house this size, it was impossible.
On Thursday, I needed to pee badly. The door to the bathroom was partially open, so I pushed it without thinking.
My little sister was there, naked, one foot up on the counter, flashing her sexy slit. She had a razor in her hand, shaving her inner thigh. Behind her on the counter sat two dildos, one pink, one clear, both clearly used recently.
“Oh!” she gasped, but didn’t cover herself. Her cheeks turned rosy within seconds. “Sorry, I should’ve locked the door.”
“It’s fine,” I mumbled, backing out and closing the door. My heart hammered in my chest. Those dildos, her pussy, and the way she didn’t rush to cover up. It was all too similar to what I’d read on that forum. I had to talk to her. Something wasn’t right.
That night, I knocked on her bedroom door. She opened it wearing just a tank top and shorts. No bra since I could clearly see her nipples poking against her white top, and also, it was somewhat transparent.
“Can we talk?” I asked.
She nodded, letting me in. We sat on her bed, and I took a deep breath. “I found something online,” I said. “A forum. About siblings who … have feelings for each other.”
Her eyes widened, but she didn’t speak.
“There was a post about a girl who sent her brother nudes on purpose, pretending it was an accident. Another about letting him walk in while she was naked.”
She looked down at her hands. “And you think I did that?”
“Did you?”
The silence stretched between us. Finally, she nodded. “Yes … that was me. I’ve always liked you. Not just as a brother.”
“How long?”
“Years,” she whispered. “I’ve wanted to tell you, but I was scared.”
“Scared of what?” I asked, patting her back.
“Scared that you’d think I’m disgusting,” she said, snivelling.
“No such thing,” I said. “I love you, and you know that.”
“Yes, you love me like a sibling but not more romantically.”
“That’s not exactly true,” I admitted.
Her eyes widened. “What do you mean?”
“When I saw that photo … I didn’t react the way a brother should. And when I walked in on you …” I trailed off, unable to finish the thought.
She inched closer on the bed, her thigh now pressing against mine. “Tell me,” she whispered.
“I couldn’t stop thinking about you. About your body, and how sexy you are.”
“I can’t stop thinking about you either,” she said. “You’re tall, I like your dark blonde hair, and you’ve always been so protective and considerate of me.”
“So where does this leave us?” I asked.
“I don’t know,” she said, looking down at her hands. “I just know that when I’m around you, I feel something I shouldn’t. Something that makes me want more.”
I reached out and tucked a strand of blonde hair behind her ear. Her skin was warm beneath my fingertips. “Maybe we should explore this feeling a bit more.”
“I think so too,” she said, and we looked at each other. Then she accidentally touched my bulge, which was no longer a bulge, but a rock rod straining against my pants. “Oh, you’re hard.”
“Yes,” I said, not being able to hide it.
“Do you want to touch me?” she asked.
I nodded weakly, but it was a nod nevertheless. She took my hand, and I let her guide me to her center, inside her shorts, and then I felt her center, her puffy, wet, pink flesh. I traced her lips, found her clit, and then I dipped lower till I found her hole. It was exciting, forbidden, and very arousing to touch my sister like that, and I saw her grin widen. She clearly enjoyed this as much as I did.
“Do you want a blow job?” she asked innocently.
“What about Mom?” I asked.
“She’s showering … I’ll try to be quick.”
“Alright,” I said and felt my heart rate rising. “Take off my shorts.”
Her 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, bobbing side to side till it finally pointed directly at her mouth.
“Oh wow,” she said, her eyes fixed on my manhood as she studied it in awe. “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 with a grin.
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. She was a bit shy and insecure at first, but it just made it feel even better.
“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.” She leaned forward, her breath hot against my skin. She darted out her tongue, giving my tip an experimental lick. Even if it was just a brief touch, 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.
“You’re doing great,” I whispered, watching her blonde hair sway as she worked her mouth over me. “But I want to see more of you.”
Her eyes flicked up questioningly, her lips still wrapped around my cock.
“Can you take off your top?” I asked.
She pulled back, a strand of saliva connecting her lips to my tip. Her smile was shy but eager as she nodded. “I’d like that.”
She crossed her arms, grabbed the hem of her tank top, and pulled it over her head. Her breasts bounced free, and my eyes widened. Her breasts were full, natural D-cups, round and firm, sitting high on her chest. The smooth skin pressed together to form a tight, narrow cleavage that dipped deep between them. Soft pink areolas spread wide across the fronts, each one circled by a small, short nipple that had tightened into a hard little point, the same rosy shade as the areolas around them. With every slow breath she took, the heavy mounds shifted just slightly, making the cleavage deepen, and the stiff nipples stand out even more against the curves.
“You’re gorgeous,” I said, reaching out to cup one in my palm. It was warm and heavy, filling my hand completely. The skin was soft, like nothing I’d ever felt before. I ran my thumb over her nipple, watching it harden further under my touch.
“Thank you … I’m glad someone likes my tits.” She opened her mouth and went back to sucking my cock.
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.
“Hmm, that’s a good girl.”
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, sis, don’t stop,” I told her. I tangled my fingers in her 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. She 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. “Oh,” 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 hot cum 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.
