Little Sister's Sex Party

#1
Information  (This post was last modified: 11-24-2025, 06:30 PM by Simon.)

Shortly after my sister Anissa and I had our own small private party, puberty began in her life. It was as if a light switch had been flipped inside her body. Her breast buds began to grow, she grew taller, pubic hair sprouted, and she began producing vaginal fluid when she was aroused.

On the one hand, I was pleased with her changes, but I also knew that these changes would cause problems in our sex life.

Anissa and I continued to enjoy kissing, touching, and playing with each other. We only had a few opportunities to try virgin sex, but still without success. We both wanted it, and I began to think she wanted it more than I did, but her young pussy was simply too small.

We still enjoyed oral sex when we had time, but we wanted more. With some practice, Anissa learned to drink all my semen without wasting a single drop. This made it easier to clean up after an encounter, but we still wanted to have intercourse.

Her birthday was coming up soon, so one day while watching TV I asked: "What do you want for your birthday?"

Without hesitation, she looked directly into my eyes and replied: "I would be happy if your cock squirted a load of sperm deep into my pussy."

"I know. I want that too, but we've tried, and he just won't go in. I know your pussy is stretching slowly, but my cock is getting bigger too," I explained.

She was about to say something when we heard Mom come out of her bedroom. Anissa looked disappointed that she couldn't talk about her birthday idea. I wondered what she was thinking. Mom walked past, but before Anissa could say anything to me, she went back into the living room and sat down.

"What do you want to do for your birthday next week?" asked Mom Anissa.

She looked at me and gave me her famous, silly smile before answering. I knew what she wanted to say, but she also knew she shouldn't say what she was thinking. I was really curious to hear what my little sister would tell Mom.

"How about a party?" suggested Anissa.

"A pajama party or just a party?" asked Mom, to get a better idea of what she had in mind.

"Just a small party," she said to her mother again.

I think I was just as confused as Mom. Anissa usually gave lots of details and said more than necessary when you asked her a question. I really wondered what my sister was thinking.

"Okay, if you know who you want, what you want to eat, and when you want to eat it, just let me know. Remember that I need time to make plans," Mom said to my sister.

“Okay,” Anissa replied.

Mom looked at me, wondering what was wrong with her little daughter. I just shrugged to make it clear that I had no idea why Anissa was behaving that way.

The next day, after school, I was in my room doing my homework when Anissa came in. She came in, stood next to my desk, and just looked at me.

I looked up from my book and said, "Hello. Did you have a nice day at school?"

"Everything's okay. Where's Mom?" she asked.

"She had to go shopping. She'll be back in a few minutes." I told her, knowing full well that she probably just wanted her pussy licked or something else sexual.

"Oh. Can we talk?" my sister asked seriously.

Since that was different, I stopped what I was doing and looked at her as I replied, "Sure."

"You know I love you, right?" she said seriously again.

"Stupid little girl. Yes. I know you love me, and I love you too." I told her before she could ask.

"You won't be angry with me if I ask you something, will you?" she asked, as she prepared to ask a big question.

“No. You can ask whatever you want,” I said.

"Promised?" she asked again.

This was starting to get annoying. And I was beginning to worry. What could a 10-year-old girl possibly ask who was so serious she wanted to make sure I wouldn't get mad at her? We'd talked about everything, including masturbation and sex, so what was she getting at? I wondered.

“Yes, I promise. Just ask,” I replied sternly.

“Bobby… your best friend, have you given him a blowjob lately?” she asked shyly.

This question really surprised me. I'd told her we'd given each other blowjobs, but I didn't understand why she was asking. Was she jealous? Was she wondering if I was gay? The conversation was getting weirder and weirder.

"Yes. We gave each other a blowjob right after school today. Why? You're not jealous, are you?" I answered her question, but our time was limited, so I tried to get to the point before Mom came home.

"No, I'm not jealous. I know you like my blowjobs best, but we can't get enough of being alone. I wish we had more time alone. I'd really love to sleep with you like we used to. That was so much fun. I also wish you could lick my pussy more often. I miss our lovemaking." She talked on and on.

"I miss our time together too. So why did you want to know something about me and Bobby?" I asked again.

"Well, I was just thinking about something. Is Bobby gay?" she asked again, an unexpected question.

“No. He enjoys sex with girls just as much as I do, but at the moment neither of us has a girlfriend and we're taking care of each other. Why are you asking all these strange questions?” I said, trying to get her to the point.

After a deep breath and a long pause, she finally got to the heart of the matter. "I know your penis has gotten bigger in the last few months, and I know that's one reason why it still doesn't fit in my pussy. I was wondering if Bobby's penis is still small or if it's gotten bigger too."

Why Bobby's penis size was important to Anissa was a mystery to me, but I was prepared to get to the bottom of it until I found out. "It's still pretty small. It might have gotten a little longer, but it's still much thinner than mine. When he's really aroused, it could be 12 cm. Why?" I practically begged for an answer.

After another deep breath and a pause, she began to answer. "I just thought if his is still smaller than yours, then maybe it will fit in my pussy." "If he can fit his in me, then it might stretch me enough for you to fit yours in me," she said to me.

The whole time she was speaking, she kept her eyes down. Her cheeks flushed, and her voice trembled. She was terrified to say what she'd said, but I guess she was desperate. She wanted my cock so badly that she was willing to let my best friend fuck her just to have my cum inside her. While some men might have been offended by the idea of their sex partner being fucked by another cock, I was the complete opposite. I wasn't just surprised. I was delighted. Not all girls would allow their bodies to be used solely to give their lover pleasure.

I reached out and placed my hand under her chin. I lifted her head until our eyes met. I could see tears of fear welling in her beautiful light blue eyes. I leaned forward and gave her a soft, loving kiss. She returned the kiss, fighting back a sob. Our heads bobbed as the kiss deepened. Soon after our lips touched, they parted again, and our tongues ventured into each other's mouths. We both began to moan as we embraced. The passionate kiss reached a point where we were both incredibly aroused.

I stepped back and said, "Shit, I wish we had more time, but Mom will be back any minute."

"Would you mind if he put it inside me? Do you think he would? Do you think my idea would work? You know... putting your penis inside my vagina." Finally, she launched into a barrage of questions.

“I’m sure he would. He’s often told me how cute you look and how much he’d like to see you naked. I can’t promise your idea will work. Maybe.” “I really wanted to be your first, but it doesn’t look like that’s going to happen,” I told her.

“I know, I wanted you to be my first too,” she admitted.

"You know we can't have sex without a condom once you get your period, and that can happen at any time," I told her.

“Yes, I know. I want your sperm in my pussy. I want to feel it spurt inside me. I want to carry you with me. Is that silly?” my little sister wondered.

"No. Not silly at all. I'd rather fuck you without a condom too. But I don't want you to get pregnant," I admitted.

"That's right. So... what do you think of my idea?" she asked me.

"Just one thing. How do you think we should do this? It's hard enough finding a place and time to play together," I asked.

Around that moment, we heard the front door open. We shared a quick kiss. She told me she had an idea and that I should think about a few more things. Deep down, I really hoped it would work, but I couldn't imagine how she was going to organize a sex party for the three of us with no adults around.

Mom walked past my door and looked inside. When she saw us together, she said, "I'm home. Dinner will be ready soon."

“Thank you, Mom,” we both said at the same time.

We looked at each other and giggled.

My sister went to her room, and I finished my homework. Later, Mom called us in for dinner. We ate, cleaned up, showered after watching TV, and went to bed. My sister and I were both really turned on after the passionate kiss in my bedroom, but the last thing we wanted was to get caught having sex.

That night in bed, I thought about the things my sister had told me. I wondered if she really had a plan or if she was just hoping something would happen. I knew she'd told me she wanted me to cum inside her as a birthday present, but I just couldn't imagine it happening. I desperately wanted to give her what she wanted, but...

A few days later, Anissa came into my room on her way to dinner and asked, "Bobby hasn't stayed here in a long time, has he?"

Knowing she should know the answer to the question, I replied, "No. It's been about a month. Why?"

Without answering my question, she said, "Tonight at dinner, I want you to ask Mom if Bobby can have a sleepover next Saturday." I tried to find out why, because it was my sister's birthday. Mom very rarely let us have friends over. We did well in school. We got good grades in all subjects. We didn't cause any trouble at home. We got along better than most siblings.

And even though Mom was a single parent, we did what she said without complaint. This time was different. It was the same day my sister was planning a party, so I wasn't sure her plan, whatever it was, would work. Anissa was already out of my room and down the hall before I'd even finished asking the question, so I had no choice but to try and weave her into our conversation while we ate. We all sat down and started eating.

We talked about school and what was happening with both of us the coming weekend. I thought it would be a good time to bring up what was going to happen next weekend. I said it to get her attention and hoped it would be a hint to my sister that I would grant her wish.

“Yes, Gabe,” she replied kindly.

"Bobby hasn't stayed overnight here for a while. Do you think it would be okay if he stayed next Saturday?" I asked, my heart beating harder than usual.

“I don’t know, Gabe. It’s your sister’s birthday and she said she wants to throw a party… I just don’t know,” she said.

"What about tomorrow evening?" she tried to persuade me to postpone his visit.

I looked up at Anissa, and since Mom was looking at me, Anissa shook her head. "No," she said, hoping I could somehow ruin her date.

I quickly made up a story and said, "Bobby already has plans for tomorrow."

That was the best thing I could think of on such short notice. I wasn't really lying. I was pretty sure he'd already planned something, but it probably could have been changed. I was just trying to fulfill my sister's wish. I still had no idea why, though.

"I just don't know," Mom still said.

Anissa then chimed in: "That's fine with me, Mom."

"But what about your party?" she asked.

"I just want a small party with four or five of my friends. I was thinking something like a lunchtime party. Maybe some games, then pizza for lunch, then cake and ice cream. I thought it would end around three o'clock, depending on what we did after lunch. There won't be much to clean up either. If Bobby comes by around three, maybe he and Gabe can help with the cleanup. After dinner, we can maybe watch a movie or two with popcorn and more cake and ice cream. It would be like having two separate parties."

Anissa begged in one of the best theatrical performances I have ever seen of hers.

"That seems like a lot of work. Besides, I'm not sure I can stay awake to watch two movies. I might not even manage one. There's a lot to do that day and I... well..." Mom resisted the whole idea.

“Please… I’ve never had two parties in one day before,” she pleaded.

She deserved an award for such a convincing story. Besides, it really was a good idea. She'd throw a birthday party during the day and a sex party in the evening, especially since Mom went to bed early. I had to let my sister have her way. Even if it hadn't worked, she couldn't have come up with a better plan. For my part, I genuinely hoped it would.

To help my sister, I said, "I'll help with the tidying up, and I'm sure Bobby can come by and help too. Then, if you go to bed early, I'll keep an eye on everything."

When I was finished, I hoped I hadn't gone too far. The last thing I wanted was to plant the idea in my mother's head that we would be doing something after she went to bed.

"Let me think about it tonight. I'll let you both know tomorrow," she finally said.

Good. She didn't say "no." If she was thinking about something, it usually meant it was going to happen. My little sister looked at me and gave me a wicked but sexy smile. We finished dinner, and to give Mom that final touch, we were extra good and helped clean up the kitchen more than usual after dinner.

Saturday morning at breakfast, Mom told us it was okay, but we both had to pitch in. She added another condition: we shouldn't make any plans for the following weekend because she wanted to rest. We quickly agreed, as I could feel my cock starting to make plans to penetrate my sister's pussy for the first time.

After breakfast, Anissa and I helped with the cleaning. We finished all the homework and soon started making plans for the next weekend. I wanted to go down the street and talk to Bobby while...
My sister called her friends and got everything ready. She had to find out who was coming, what kind of pizza they all liked, and when they would arrive. I just hoped they were the same ones I'd played sex games with at my sister's pajama party.

On my way to the door, my sister stopped me and asked, "Are you going to Bobby's?"

“Yes,” I said, assuming she already knew that.

“Okay…” she said, making sure Mom wasn’t around. “Make sure he knows he can’t come all week…” Then, after a pause, she said, “That goes for you too, okay?” She finished with the question.

“Should I tell him what you’re planning?” I asked, somewhat confused.

“Isn’t that why you’re going in person?” she asked. “I was just about to invite him and tell him about your party and that he needs to help clean up after your little friends leave. I didn’t call because you’re on the phone calling your friends and making plans,” I explained. “No… No… No…” she said, exhaling disapprovingly. “First, you need to find out if he wants to put his cock in my pussy. If so, tell him he can’t come all week because I want his cock as big and hard as possible. I want him to stretch me so you can put yours inside me.”

"Okay. Anything else?" I asked before heading out the door.

Anissa looked down and asked, "Yes. Would it be mean of me to tell him that he's not allowed to come inside me?"

“Yes. You can’t just use him like that. You should let him come,” I said, as I felt my cock start to leak precum from all the sex talk.

"But I want you to come inside me first... Okay... What if he puts it inside me... and before he comes, he pulls it out? Then I'll suck it and drink his... sperm. And after you've come inside me, he puts it back in and comes inside me. It's not that I don't want him to come inside me, it's that I want your sperm first."

She negotiated.

"You know he'll know we did something, and he'll... see me fuck you for the first time. He'll also... want to fuck you again in the future." I warned my little sister.

"We'll see. I don't want you to get upset if I let him do it with me again sometime. I want you, and I want your sperm inside me. That's the only way I can do it with you," she admitted.

"Okay. I'll tell him and see what he says. What if he doesn't do it until he cums inside you?" I asked her, just to be on the safe side.

She looked really disappointed and said, "That's okay."

I walked down the street. I just couldn't get that disappointed look out of my head. I really hoped I could convince him to grant Anissa's wish.

“Wait! What have I done?” I shouted at myself.

I was just about to walk up Bobby's driveway when it suddenly hit me. I was about to tell my best friend that I'd not only kissed my sister, but also given her sensational oral sex. He was also about to find out that I'd tried to have sex with my 10-year-old sister. And I was going to invite him over so I could have sex with her and shoot my sperm into her little pussy.

"I must be crazy," I thought.

But she wanted it. It was her idea and her plan. I loved my sister and wanted to make her happy. Besides, it was her birthday wish. Once again, I thought about how I had rationalized what I had already done, and so I simply continued with the same thought process.

I took a deep breath and rang the doorbell. His mother opened the door and invited me in. She called him down from his attic room. He saw who it was and told me to come up. I knew we'd be undisturbed up there, because that's where we all had our own sex games. Luckily, the stairs creaked, so we knew when someone was coming up. I went inside and closed the door. We chatted for a bit before I got down to business.

"Did you know that my sister's eleventh birthday is next Saturday?" I asked first.

“I knew it was coming soon, but I wasn’t sure when,” he admitted.

“She’s throwing one of her parties again,” I said, trying to gauge his reaction.

Not what I expected, but his answer opened the door for me:

"You probably want to stay here so you're not with all those giggling little girls."

"No. They're not so bad," I said when he gave me a strange look. "Actually... um... I'm actually looking forward to it," I said, trying to pique his interest in my thoughts.

"Why? Are you allowed to throw darts at her?" he asked childishly.
