Marisha and I have been very friendly since childhood. Since my father got married for the second time and I had a sweet younger sister, the need for other playmates has disappeared - Marinochka always played with me. I always liked her laugh, smile, outfits, bows and even her smell. My sister smelled of milk and flowers - I loved coming home from school early and lying in her bed for a couple of minutes, inhaling this wonderful aroma. But it was impossible to linger for long, otherwise Marina would notice that the bed was rumpled and go into bear mode from a fairy tale - "Who was lying on my bed?!" Despite the very special relationship that my sister and I had developed (I constantly forgot that she was a step-sister and in my thoughts I just called her sister, and she called me brother), she categorically limited her personal space, although not always and not everywhere.
And our relationship was special for another reason - right after her eighteenth birthday, my sister came to me as usual to play fighting games on the console. But quite unexpectedly, instead of turning on the device and picking up the gamepad, my sister blushed and, looking down at the floor, said that she would like to suck me off regularly. Just like that, without beating around the bush. I almost fainted when I heard this. Marisha then clasped her hands, sat me down on the sofa and brought me some water to drink.
"I'm sorry, I shouldn't have dumped all this on you... It's just... Arkash, you're my stepbrother, I've been dreaming about this for so long, but I couldn't tell anyone, I wasn't eighteen! But now..."
It turned out that she had such a desire not so long ago - immediately after watching the first porn video. She came across some Japanese three-hour opus about a brother with two sisters, merciless censorship in squares and with a very, very large amount of blowjobs. It's interesting that the Japanese actresses in that video swallowed all the sperm with pleasure. Marina was so inspired by what she saw that she decided to experience these sensations, since her brother, that is, me, was always at hand.
But then I rejected her request in horror. My penis was already sticking out in my shorts from such conversations, I blushed, my gaze was glued to my sister's cute face, to her erect nipples under the T-shirt, to the beautiful outlines of her breasts and butt under the fabric of her clothes. And yet, I found the strength to say no. However, I didn't have enough for a long time - as soon as Marina folded her hands on her chest imploringly and made a touching face, I gave up. Only in the end, before diving into the abyss of pleasure, did I remember the danger:
"What if our parents..."
- Don't worry, they went on a date! - and Marina giggled. Indeed, despite the fact that our parents have been married for fifteen years now (Marina was three years old when my dad married her mother), they still sometimes behave like a couple of young lovers - they go on dates, make out in hallways, and even kissing in public!
"Nooo... I haven't even kissed anyone yet!"
"Me too! My first kiss will be... now! With your dick!" - Marina whispered nervously and knelt down in front of me.
I gasped with anticipation, my penis swelled even more and began to painfully rest against the elastic band of my shorts. A rich imagination immediately came up with a scene of my sister putting her mouth on my dick, moaning at the same time. But we didn't succeed in anything like this the first time - as soon as Marina's fingers pulled the shorts down, freeing the penis, I felt it twitch and pulsate.
"Brother, how huge he is! Twice as much as in that video!" - my sister opened her mouth in admiration and it was there that the first droplets flew. And then whole lakes. Gradually, Marina's entire face was covered with sperm, it even flew into her left eye and her sister was forced to close it. White streaks dripped down onto his T-shirt and hung from his hair and chin in cool, trembling icicles.
"S-sorry, I didn't mean to do it so quickly... It's all because I haven't finished yet in the morning!" - I made excuses.
The sister's only open eye flashed playfully from under the sperm streaks.
"Don't worry, everything is fine. Just bring me some napkins!"
I immediately rushed for the box while my sister was sitting in my room, covered in sperm. My heart was pounding - what if the parents forgot something and came back and their daughter looked like this?
The napkins helped the matter - it probably took about five of them to completely clean Marina's face. And then the last crumpled napkin flew into the trash - Marina smiled at me.
"Well, now you won't cum so quickly?"
I shook my head. Suddenly Marina grimaced.
"Oh, how can it be, you came so much, and I didn't taste a bit!"
"Uh...Are you sure you'll like sperm? After all, many girls don't like her!"
"I am not many! I'm sure I can easily swallow your entire next portion! And as big as the first one too, well, after training for sure."
I sat down next to my sister and tried to calm my rapidly beating heart. The girl put her head on my shoulder and hugged me.
"And when... When can you do it a second time?"
"Yes... I think it's already..." I glanced down at the penis, which was already tearing my shorts again.
"Is it true?" - Marina was delighted.
She knelt in front of me again and happily fished my dick out of my shorts. She squeezed him with her hands and even leaned him against her cheek. Her every movement resonated with sparks of pleasure in me. My dick was shaking, ready to explode, but this time I really wanted my sister to taste the cum. So, when I felt the finish line approaching, I simply grabbed Marinochka by the back of her head and, standing up, poked her lips with the tip of his penis. The little sister immediately opened her mouth and pressed her lips together on the throbbing penis. It even seemed to me that it seemed to vibrate on her tender tongue!
Little sister hummed and widened her eyes. She puffed out her cheeks and carefully removed herself from the penis - a white slippery thread now stretched from her lips to the penis. Marina tore it apart with her fingers and looked at me. She hummed in protest and pointed to her mouth.
"What? Taste? Not pleasant, right?" - I grabbed a pack of napkins, since it was standing right there and prepared for Marina to simply spit out sperm into the napkin. But that was not the case! Little sister closed her eyes, squeezed, and with great effort made a swallowing movement. And then one more! And she coughed after that - some of the sperm did flow down her chin.
"It's delicious, really. But... Very unusual. And it stings! It stings my tongue!"
"Does it sting?" - I was surprised. Suddenly a wonderful idea came to my mind - I leaned over to my sister and licked the droplets from her chin and neck. The sperm turned out to be salty, spicy and... really stung the tongue!
"Yes, exactly! Maybe it's because I like to put a lot of spices in my food?" - I scratched the top of my head, puzzled. My sister looked at me with concern.
"But can... can boys eat their own sperm? I've never heard of this!"
"As you can see, they can," I shrugged. "Come on, next time, if you feel that the portion is too big, just share it with me, okay? So as not to waste napkins... At the same time, we'll kiss, for the first time, by the way!"
- Braat! - Marina completely suddenly hugged me and moved her face to my lips. - Let's kiss right away.
And I kissed her lips, smeared with my sperm. And then he penetrated his tongue into his mouth, in which a solid portion of nectar had just splashed. Blood was pounding in my temples, I wanted to grab my sister's breasts and butt and start undressing her - but I held back, not knowing how she would react to this. So we just kissed - with drooling, hugging and moaning. My penis stood proudly between us and in the process of caressing my sister kept pressing it to my stomach.
Feeling the hardness, Marina looked down and immediately dived towards him - I hoped that at least for the third time I would not cum right away and would finally feel what a blowjob is. My sister kissed me on the top, grabbed my penis with her palms and, grabbing the head with her lips, began to move up and down, generously covering the sensitive area with saliva. I was shaking with joy, bouncing on the couch impatiently, trying to penetrate deeper. Marina wiggled her tongue, rolled the penis by the cheek and sometimes released it, giving it a rest and herself a breath of air. I didn't touch my sister, letting her figure out the new sensations herself.
About half a minute later, I felt an electrical impulse gathering inside again - a harbinger of ejaculation.
"I'm going to cum... again!" - I whispered chokedly. Marina froze, not knowing what to do, and then suddenly impaled herself on the penis with force, pushing it down her throat. Tears welled up in her eyes. I grabbed her head a little and lifted her so that my dick discharged not into her throat, but onto her tongue. This time Marisha didn't moan so much when the sperm got into her mouth. But, remembering the agreement, I leaned over and took part of the portion with a kiss. We swallowed synchronously, and then showed each other clean tongues.
"Braaat! Now I want to swallow it all the time!"
"Well... You don't have to swallow, there's one very cute actress in Japanese porn - Rion Izumi, so she very rarely swallows sperm. The boys cum in her mouth, and she usually just lets it out - it turns out very sexy."
Marina had never heard of such an actress, so I turned on one of Izumi's videos on TV, the title was something like "A world where blowjobs are a common thing". I enjoyed watching Marina enjoying what was happening on the screen.
"Damn, she's so cute!" - my sister exclaimed after one of the scenes. "It's a pity that there are no subtitles, it's not clear what they say."
"It seems to me that you are somewhat similar to her!" - I stroked Marina on the head, in response she lightly poked me in the shoulder with her fist.
"Hey, let's do it without it!" - and we continued watching the film. I still felt a strange feeling on my tongue - the swallowed sperm was taking its toll. I can imagine what's going on in my sister's mouth - she swallowed much more.
"Listen, wouldn't you like something to drink? Maybe orange juice?" - I ran to the kitchen and poured us a glass of sweet orange drink. After that it seemed to feel better.
"She's so cutely shy..."
"Well, it's not so noticeable here. There are films where she plays a daughter, and also with a tutor, where it manifests itself much more clearly."
"Yeah, boys like shy girls..." Marisha drawled.
"Not for everyone and not always."
"What about you?" - my sister looked at me worriedly. "Right off the bat, I came and started talking about... about this..."
"Don't worry, all this can be combined," I put the glass of juice on the tables and turned to my sister. - You can sometimes be shy and touchy, sometimes attack the dick if you want, or even ignore the fact that it's in your mouth - play on the phone, for example, or talk to your girlfriend.
"Yeah?" - Marina raised her eyebrows in surprise. Obviously, she didn't come across such videos.
