My younger sister

My name is John, I am 18 years old, and I live with my father and my 15-year-old sister Emily. My parents divorced ten years ago, and my mother started a new family, but we still see each other often. She didn’t part on bad terms with our father or with us. My father sometimes brings a girlfriend home, but he mostly lives his sexual life outside the house and raises us alone.

About two years ago, something happened that probably shouldn’t have, but today no one regrets it, as it sparked a series of great experiences later on. One evening, I came home, and from the unfamiliar women’s shoes, I realized my dad had a visitor for some fun. Sure enough, my father was sitting with his new discovery, Kate (a beautiful young black-haired woman—Dad always had taste), and they were sipping wine. He immediately introduced me, inviting me to join them, pour myself a deciliter of wine, and chat about ourselves and such. It was clear to me that I’d be interrupting soon, so I politely declined and went to my room.

On the way, I ran into my sister, and we exchanged glances, knowing what would happen in the living room that evening. At thirteen, my sister knew her stuff; the internet reveals everything these days. She was still a virgin but stretched her mussels every night, which was hard to miss through the walls of our rooms. I have to say, at thirteen, she already had a great body—small breasts but already noticeable in the palm of your hand, blue-eyed with raven hair, simply stunning.

She didn’t bother much with modesty at home, often skipping panties under her nightgown and not being shy about it. Sometimes she subtly exposed herself, so I often saw her bare bottom, tight crotch, or slightly revealed breasts when she bent over. It even aroused me at times, and in the evening, in the bath or bed, I’d masturbate thinking about her naked body. Puberty was hitting me hard, so I didn’t give it much thought.

That evening, when my father brought home the black-haired beauty, I, as usual, had a nice buzz in my pants. I knew the orgy in the living room had probably started, and I wanted to tune in by listening or carefully peeking before going to the bathroom to masturbate before my shower. I quietly approached the living room door when I saw that I wasn’t the only one with this idea.

My sister was peeking through the crack in the door, from where faint female moans were coming, and she was touching herself in her panties.

Not to startle her, I whispered, “What are you doing here?”

She was startled but stayed as quiet as a mouse, turning to me with her hand still in her panties.

“Dude!” she whispered, and we both smiled, realizing we had the same perverted idea.

My cock was half-hard, and I wanted to peek inside too, even if just for a moment. My sister turned back to the crack, and I stood behind her, watching as Dad took Kate from behind. My cock started to swell nicely, and suddenly the tip of my glans touched my sister’s beautiful buttock, which literally vibrated with excitement. I swallowed hard—‘this is weird,’ but it turned me on immensely, and I was close to cumming on her ass.

My sister was startled but didn’t move an inch. It didn’t throw her off; instead, she slowly and lightly guided her cleft between her buttocks to my glans and began gently rubbing it. At that moment, neither of us paid any attention to what was happening in the living room and focused only on each other. But after a few seconds, the sound of the window opening in the living room interrupted us; it was clear they were done for the moment, and we quickly and quietly ran to our rooms.

I lay on the bed, staring into the semi-darkness, processing what had just happened with intense arousal. I wasn’t a virgin anymore, but this was something completely different from being with girlfriends. I was afraid to finish myself off, feeling very strange.

After a few minutes, the arousal subsided a bit, and I decided to try to sleep and think it over in the morning.

Suddenly, I heard a soft whisper from the door. “Bro…”

My sister stood in the doorway with a wide smile.

“What’s up?” I said, and she slowly walked to my bed and sat on the edge.

“Dude, what was that? You almost pushed it into me.”

“You were the one rubbing your ass on me!” I replied, and now I was smiling too.

I saw my sister’s hand approaching my crotch and landing on my still half-hard penis. I wanted to say something, anything, and remove her hand from my cock, but something held me back, and I couldn’t muster the slightest resistance. On the contrary, I felt it quickly harden and grow in her hand, surprising her a bit as it twisted and swelled in her palm.

I ran my hand over her smooth thigh, and my sister got extremely aroused again. I slid my hand under her shirt, and of course, she wasn’t wearing a bra. Finally, I was caressing her incredibly cute little breasts, and she was moaning wildly; no one had ever touched her like this before. She didn’t stop stroking my cock through my pants, and I took off her shirt. Her small nipples were sticking out like crazy.

I caressed every part of her body, and she writhed with the excitement of a young chick. I lay on my back, and Emily sat on top of me, rubbing her pussy wildly against my penis. I pulled down my pants to my knees, and my cock stood harder than ever.

My sister paused, looked me straight in the eyes, and with one hand, she stroked her pussy through her panties. Still looking at me with a sly smile, she moved the panties aside and slowly pressed her hole against my swollen glans.

Carefully and incredibly slowly, she slid it into herself.

I wanted to thrust deep into her right away, but I knew she was still a virgin, and I’d ruin everything by rushing. So I let her slowly slide her beautiful pink lips up and down, going deeper with each movement.

Emily was so aroused and scared of losing her virginity that she wasn’t even breathing, but then her determination broke, and she slowly sat down as deeply as possible on my cock. She looked at me in surprise, as it didn’t hurt her at all; she had probably already lost her virginity during her wild bedroom masturbation sessions.

Then she started sliding up and down again, this time regularly and deeply. She twisted her ass beautifully, which I held firmly and kneaded. I couldn’t get enough of that beautiful, small, and firm ass. She started moaning louder and picking up the pace. I knew I was about to cum any moment and tried to hold back so I wouldn’t cum inside her.

“I’m close, wait…” I managed to say just seconds before ejaculating, but my sister sat down as deeply as possible, clenched her thighs, and started riding her ass.

I started cumming heavily into my sister’s sweet cave, and even though I knew I shouldn’t, I couldn’t bring myself to pull out, and I kept cumming and cumming.

Emily tossed her long hair and smiled from ear to ear. She realized she was now a woman and that it had happened without the pain she had feared from older girls’ stories. She lifted herself up and looked curiously at her pussy as my semen dripped from it. I started caressing her body again, running my hands over her little breasts, and in my head, I was preparing for the next round. But then we were interrupted by some movement in the hallway;

my sister got a bit scared and said, “I better go before they catch us… thanks, bro.”

She gave me a short but juicy kiss, got up, and quietly ran to the door. She peeked into the hallway, saw no one, and disappeared into her room. I had just enough strength to cover myself with a blanket and think about my sister, how she could have turned me on like that. I realized what would happen if she got pregnant because I hadn’t been careful, but the pleasurable feeling of tasting forbidden fruit overwhelmed everything. With this feeling, I fell asleep contentedly.

In the morning, I went straight to the shower after waking up. My sister peeked out from the kitchen: “Hey…” she said with a wide smile, and I responded exactly the same. I finished my shower quickly because I was quite hungry. I rushed into the kitchen in just my pants, where Kate in a robe surprised me a bit. Dad had gone to work early, and she said she’d cook lunch for us and stay another night. On the table, I already had breakfast prepared by Kate, so I thanked her and started eating hungrily.

After a while, I noticed a subtle mischievous smile on Kate’s face, which I attributed to Dad’s performance last night; he must have given her a good time. But my sister had the same expression. I didn’t know what to think. But Emily quickly filled me in.

“Kate heard us last night when she went to the bathroom; we were probably too loud.”

I froze and played out the scenario of the mess that was about to unfold in my head.

“I won’t tell anyone, but it really surprised me. Do you do it often?”

After Kate’s words and calm voice, I felt a huge relief.

“No, no, it was the first time yesterday, you know, we heard you and Dad going at it, and somehow it all just happened.” I managed to say. But I kept to myself that I had cum inside my sister.

“So it just happened…” Kate laughed, and my sister and I laughed with her.

“…well, as I said, I won’t tell anyone, but…” I expected a lecture on how wrong and perverted it was, which I obviously knew, but that’s what turned me on so much—fucking my sister’s amazing young body.

But Kate approached me, opened her robe, and underneath, she was completely naked. She took my hand, placed it on her thigh, and gestured upward to where I should continue. I stared at her in disbelief and moved my hand up to her pussy. As soon as I brushed her lips with my finger, she let out a soft moan. She also had a very beautiful body, unlike my sister, she was a real woman.

I had her pussy right in front of my face, so I immediately took advantage of it. I ran my tongue over her slit as much as I could. I flicked her clit with the tip of my tongue, and she moaned a bit louder. I glanced at my sister, who was staring in disbelief and couldn’t get a word out. She realized what Kate meant by ‘I won’t tell, but…’

Kate took my hand and said, “Come on,” leading me to my room. She stopped by my sister and asked, “Do you want to watch us?”

“Yes,” my still wide-eyed sister managed to say and followed us.

Kate led us to the room, sat us on the bed, and took off her robe. Her body was shaped by God himself, I thought to myself. She knelt in front of me and pulled down my pants. My cock was already half-hard and dangling. Kate expertly grabbed it in her hand and stroked it a few times. It was now hard as a rock.

She looked at my sister and said, “Now I’ll give your brother a little blowjob, so don’t be shy and join us anytime.”

Kate also found this whole thing quite perverted, but it turned her on just the same. My sister nodded and slowly began caressing herself, moving her hand over her pussy and back up her body. But Kate already had my cock almost entirely in her mouth, lightly and slowly sucking. No one had ever played with it so skillfully before. She sucked my glans with her lips until I arched my back. I knew I wouldn’t last long like this and would soon cum. But Kate understood and only blew very lightly.

Meanwhile, she glanced at my sister, who was getting pretty hot and wildy rubbing her crotch.

“Take off your shirt,” she told Emily and let go of my cock for a moment to pull down her panties.

My sister’s pussy was completely wet, and her nipples were swollen like two teats. Kate started blowing me again, and I kissed my sister’s tits. She, already very aroused, stroked her slit and moaned like crazy. Kate also had one hand busy with her own pussy but still focused perfectly on blowing me. I was about to cum, but Kate sensed it and lightly squeezed the base of my cock. My sister writhed in orgasm, which didn’t help me much now, but Kate still successfully delayed my ejaculation.

After a while, she let go, lay down between us on the bed, and spread her legs. She grabbed my ass, pulled me toward her, and I guided my cock to her pussy. It slid in like butter.

I started fucking her quite wildly, thrusting until it slapped, and Kate was enjoying it immensely, which pleased me that I could satisfy an experienced woman.

“Come to me, Em,” she said to my sister, who was still catching her breath from her orgasm. Emily moved her crotch to Kate’s head, and she started expertly licking her. My sister was immediately back in the mood and started moaning loudly. She watched as I fucked Kate and imagined herself in her place. But after a few seconds, she got extremely aroused and blurted out, “No, no, I can’t, I can’t hold it, I’m going to pee!!!”

But Kate didn’t stop and eagerly started sucking my sister’s clit. At that moment, my sister let out a wild moan, and a golden stream of water spurted from her pussy. Kate pressed her entire mouth against her pussy and started sucking everything in and swallowing. But I couldn’t hold back anymore and powerfully ejaculated streams of semen into Kate’s pussy.

I leaned on her to reach my sister’s pussy and said, “Wait, me too…”

Kate let me go to the still-peeing pussy, and I sucked the rest of what my sister had given me. When it seemed like it was all over, Kate massaged my sister’s clit, and she started peeing lightly on Kate’s tits. Kate massaged them and rubbed the juice into her skin. My sister lay down next to us and started laughing.

That something had gotten on my mattress didn’t bother me at all at that moment. We lay there for a while, intoxicated, and took turns kissing each other.

“Alright, kids, now go take a shower, and I’ll quickly cook something for you.”

My sister and I didn’t pay much attention to that lunch; in fact, I don’t even remember what Kate cooked, but it was probably good. We knew that a proper and exciting fuck awaited us in the afternoon. But more on that next time… 🙂
