“Dad, I saw the coolest model car in the store today. Do you think you could get it for me? It only costs $9.99,” I said one evening at dinner.

Before he could answer, my little sister spoke up and said, "I found a dollhouse that my doll would love to live in. Can you get it for me? Please..."

Dad slowly looked up from his plate before turning to look at Mom. She smiled but said nothing. Then he turned to look at my sister and me before finally speaking.

"Seriously? I can't just buy you both everything. William, you're 14 years old now. Summer's almost here and you'll be finishing school soon. Why don't you go out and try to get a job to earn some money?" he urged calmly.

"And me? I'm not old enough to work yet," my sister said to Dad.

"I know, Cindy. But you're 12 and old enough to babysit a little, or maybe help someone in the neighborhood with their laundry or housework. There are lots of families in the area who could use some help."

“Maybe you two could work together,” Dad suggested. We knew it was better not to beg or plead, so we just ate dinner and set off. Cindy and I spent the next few weeks looking for jobs in the neighborhood, but nothing came of it.

The last week of school arrived, and the weather was really beautiful, so we spent more time with our friends than looking for jobs. We hadn't given up, but we were running out of ideas. The week after school ended, our cousin Nate came to visit. Of all our relatives, we knew him best.

He was 16 years old and wanted to attend the local college. So he asked if he could stay with us for a week while he looked around the school and familiarized himself with the customs of the town. He would be staying in the dormitory, so he wouldn't have to find a new place to live.

One afternoon, while both our parents were at work, Nate and I were watching a movie on TV. It was one of those teen movies with just enough shots of girls in bikinis and half-naked boys to create sexual tension. Cindy was next door with her friend, so Nate figured it was pretty safe to openly say what he thought about the girls' breasts and butts and how much he'd like to shoot a load of cum inside them. Between his talking and the sexy scenes, I was rock hard and about to go to my room and jerk off.

"Dude. I really need to cum. Do you know anyone who's good at giving blowjobs?" Nate asked me quite openly.

A little embarrassed by the question, I said: "No. Not that I can think of anything."

What none of us knew was that Cindy had come into the house and was just around the corner from the living room. She was apparently close enough to clearly hear what had been said, because when she came into the room, she started asking questions.

"What is a blowjob? William, can we make money with that?" my little sister asked naively.

Nate laughed at her childish question until he thought about it more openly. "Well, because... there are some who can make money from it, but generally the guys just keep doing it until they get it for free."

She still didn't know what it was and asked, "What is it anyway? Can I learn it? Is it difficult?"

I had to stifle a laugh at my sister's questions. I knew what it was, but I'd never given or received one. Actually, I didn't even know how to do it. I glanced down and noticed that Nate had an erection and wanted to let him continue the conversation with Cindy.

"If I tell you, will you promise not to tell anyone where you got it from?" Nate asked before answering her questions.

“I promise,” she answered honestly.

"Okay. Come here and sit next to me." He began with: "A blowjob is when a man or a woman opens their mouth and a man puts his penis in it." He explained it to her.

Cindy's mouth fell open and she screamed, "Ew!" But then, interested in more information, she asked, "And then?"

"Well, the guy then puts his penis in the other guy's mouth and takes it out again while they suck. They might also play with the guy's balls and even his asshole if they're really in the mood." 

"If they're good enough, the guy ejaculates into the mouth. The other guy usually swallows the semen. Sometimes there's too much and some leaks out. How it all turns out depends a lot on how good they are at giving head," Nate explained in detail.

“Oh,” Cindy said soon after.

I looked down again and saw his cock bouncing up and down in his baggy shorts. I could tell he was about to come, but I wasn't sure what else was going on. I was just as hard, but it wasn't as noticeable because my cock wasn't that big. I guess Nate needed his orgasm more than I'd initially thought, because what he said next really surprised me.

"Cindy, do you want to give it a try?" our cousin asked bluntly.

"Mmm... I don't know," she said slowly. Then she looked at me and asked, "What do you think, William?"

Cindy and I were quite close. For siblings, we got along very well, but we'd never actually talked about sex before. Once, she accidentally walked in while I was masturbating, and I let her stay and watch as I came. She didn't tell anyone, and nothing else was said about it either, so I assumed she wouldn't say anything this time either.

"If you want to. It's your decision. It might be useful when you're older anyway," I said, urging her to agree.

"Okay, I'll give it a try," Cindy finally said.

Exactly what Nate had hoped for. With a broad smile, he then began making suggestions. He said he should show me by giving me a blowjob first. Once Cindy had seen how it was done, she could give one to our cousin. We all agreed, and soon Nate and I were completely naked. I think Cindy liked seeing us both naked because she had a silly grin on her face as she giggled.

Her gaze was drawn to Nate's 16 cm hard, average-thick penis, completely covered in hair. Mine, on the other hand, was only 14 cm long and had just a few hairs. She looked at Nate's, then mine, and then back at Nate's. She loved watching them bounce up and down without being touched.

"Cindy, watch me closely," he said as my cousin's mouth slowly enclosed my throbbing cock.

I had never let anyone but myself touch my cock before, and feeling his warm, wet mouth around my shaft was almost more than I could bear at that moment. Then he grabbed my balls, and I felt him start sucking on my shaft. As his grip tightened, I felt him slide his head up and down on my lap while he fucked my cock with his face. I had never felt anything so pleasurable in my life. His hands, touching the base of my cock and my balls while his mouth bobbed up and down, had completely taken me by surprise. Within minutes, I had a powerful, earth-shattering orgasm.

“Mmmm… Ohhh… Yeahhh… There, right there… Oh fuck… Oh fuck… Oh fuck… I’m about to come…”, I moaned loudly.

This prompted Nate to speed up the pumping motion while simultaneously sucking harder on my cock. His hands began gently kneading my balls as my semen made its way down the shaft. To further accelerate my orgasm, he started pumping my cock with one hand while his face moved up and down my lap. His other hand gripped my balls tightly as my semen gushed from the tip of my cock.

A natural reaction kicked in, and my hand grabbed the back of my cousin's head, pulling him tightly into my lap and shoving my cock down his throat as my load shot deep from my body. My hips pumped against his face as the semen spurted from my cock.

As the orgasm was almost over, I went limp. My hands released Nate's head and fell beside my body as I began to relax. Nate sucked my now-limp shaft dry and withdrew. He turned, looked at little Cindy, and smiled. She smiled back but was soon surprised when her cousin kissed her. I watched and noticed that after opening her mouth with his tongue, he squirted a mouthful of my semen into her mouth so she would know what it tasted like. When the kiss ended, she looked at him and smiled. "That's delicious. Kind of like a semen shake." She giggled.

While he was giving me a blowjob, the movie we had just watched, my little sister's giggling, and the knowledge that he was about to put his big cock in the mouth of a 12-year-old girl, he was close to exploding. Nate quickly laid Cindy down on the couch and moved his stiff cock close to her face.

"Open your mouth," demanded Nate.

As soon as her lips were parted, he began to guide his shaft into her. Her mouth opened wide so that his shaft could slide in. When he was about halfway inside, he instructed her to close her mouth and be careful not to bite. She did as she was told.

I knew she was doing it right because Nate groaned loudly: "Oh... shit. That feels great. Exactly what I needed."

He began pumping his cock in her mouth and pulling it out again until she understood what he was supposed to do. Then he told her to try it on her own. Once again, she did it perfectly, which made Nate cry out in pleasure again. He took her small hands and guided them to his balls and the base of his shaft. Soon she was jerking him off while sucking as much of his cock as she could. Nate desperately needed release, because it only took five or ten minutes before his sperm started flowing.

"Here I come, baby. I'm about to give you a fucking big load. Oh... SHIT!" he screamed as I saw Cindy shocked and hot sperm spurting down her throat.

She took what she could, but at some point she started to gag. Nate pulled out and ejaculated the rest of his load onto her face, neck, and T-shirt. After Cindy got over the surprise, she was pleased to have given her cousin a great blowjob. He gave her a loving, passionate kiss and licked his own semen off her face.

While they were kissing, I ran and grabbed a wet cloth and a towel to clean her up. I cleaned her face, neck, and T-shirt as best I could. Nate told her she'd done a great job and that with a little practice, she could become the best blowjob giver around. Unfortunately, Nate's time was almost up, and since our parents had the rest of his visit off, we couldn't have any more sexual activity.

The following Monday, Nate went home, and Cindy and I were alone for the first time. It was summer, and we knew what to do and where to go. Since Cindy was 12, I was told I didn't have to be home with her all summer. She was spending a lot of time next door with her friend anyway. Cindy and I started thinking about ways to make money. One day, while she was out, I went for a walk, hoping to find something I could earn some money with. Not far away, I spotted a large cardboard box on the sidewalk. The bottom was missing, but the rest seemed intact. It had come from a new dishwasher.

I assumed the homeowner had installed a new dishwasher and put the cardboard box out for garbage collection that same day. Suddenly, an idea struck me. I picked up the box and examined it. It was quite light, and although it was fairly large, I could easily carry it. I took it home. I took it to my room and started making plans. I still had to figure out what to tell my parents when they asked what I was going to do with the box. Finally, I decided on a playhouse in a fort. Looking back, I really wonder if they believed that explanation. It was lame.

Later that same day, Cindy came home and saw the box in my room. She asked why I had it and what I intended to do with it. I had her sitting on the floor and placed the box over her. I asked if she had enough room to move around and if she was okay under the box. She said everything was fine, but she was confused about what I was planning. With glazed eyes, I began to explain my idea and how we could work together to make money. I told her that before I told her anything more, she would have to agree not to tell anyone about my idea, and that it was okay if she didn't like it. She agreed, and after a short pause, I began to explain everything about my plan to make money.

"You liked giving Cousin Nate a blowjob, didn't you?" I began.

With a giggle in her shy voice, she replied: "Yessss..."

"And you liked the taste of semen, didn't you?" I confirmed my thoughts.

Giggling again and with a glassy-eyed look, she replied:
"Um... Hmmm..."

"So, how would you like to give a blowjob to some of my friends?" I asked openly.

She looked at me in astonishment and said sternly: "I don't know. My cousin is one thing, but the ones I see at school? They might say something or insult me and stuff."

"That's what the box is for. I'll cut a round hole in it and put the box over your head. When the guy comes into the room, he'll pull it out and put it in the hole. You can suck them until they come, and they'll never know who gave them such a great blowjob. And when they're gone, I'll take the box off you," I explained.

“I still don’t know. If they see you and not me around, they’ll know.” She insisted.

“I’ll just tell them you’re at a friend’s house and that the person in the box could be anyone,” I said, trying my best to convince them.

"What if Cousin Nate only said I was good? Maybe I'm not as good as he claimed. He did say I need practice," she said, as it looked like she didn't feel like it.

All the talk about blowjobs and my sister sucking cocks had really gotten me hard. Besides, I hadn't come in a few days and wanted to cum anyway. I pulled down my shorts and underwear to let my hard, 14 cm cock slide out.

"Here. Get it for me, and I'll tell you how good you are," I said to her.

Her eyes glazed over and a smile flickered across her face. "Really? I can give you a blowjob?"

“Sure.” Why not?” I replied, confused.

"I just thought you didn't want me to suck your cock," she replied.

"Why do you think that?" I asked curiously.

"Because you never tried to make me do it," she replied.

"Well, I do," I told her quickly, as I swung it back and forth.

I sat down on my bed and she quickly took my glans into her mouth. Damn, that felt good. I wasn't sure if it was because she was my sister or her mouth was smaller, but there was just something about being blown by my 12-year-old sister that brought me to climax instantly. She started sucking me while playing with my balls. I watched her head bob up and down in my lap as her blond ponytail bounced against her thin back. She'd been sucking me for about five minutes when she hit a very sensitive spot, and I immediately felt the semen spurt from my balls and into the base of my cock.

"I'm coming." Damn, I'm coming hard!" I shouted.

Cindy got ready, and just as the semen shot from my cock, I grabbed her head and pulled her tightly against my crotch. My body trembled as I ejaculated a massive load. The more I trembled, the harder she sucked until she couldn't take any more. I let her go while I was still spraying my semen. I hit her face and all over her little shirt. I gasped and moaned so intensely I thought I would die of pleasure.

Once I'd composed myself, I told her it was just as good, or even better, than Nate's blowjob. She smiled as the semen...
dripped from her buttocks onto her shirt.

"I think we need to work on you being able to drink a whole load of semen, and a little more practice wouldn't hurt," I told her. Then I asked, "Do you want to try it?"

"Okay. I'll try, but if it doesn't work out, I don't want you to be mad at me." She negotiated.

"Deal," I said.

"Deal," she replied.

We practiced several times a day for the next few days. Then, on Friday, I was woken up when a load of sperm spurted out of my balls. I opened my eyes and saw my little sister sucking the sperm off my penis.

Cindy pulled away from my slowly dying penis and asked, "Did you like your wake-up call?"

“Yes, really,” I gasped. Then I quickly asked, “What time is it? Where’s Mom?”

"It's 9:00 a.m., and Mom left a few minutes ago." She giggled.

Then I relaxed and pulled her into bed with me. I held her tight as we fell asleep again. A short time later, we got up and had a snack before working out the final details of our new business. We decided to charge ten cents per minute for a blowjob. The time would start as soon as the guy put his penis into the opening of the box and end as soon as he pulled it out. We estimated that an average blowjob would last between seven and ten minutes.

Cindy was to get half the money, I the other half. The only thing she still had trouble with was drinking a full load. To avoid stains on her clothes, we agreed that she would only wear panties under the box. The only one who would see it would be me, and I really wanted that. Later that afternoon, I said, "Let's do a dress rehearsal." "What do you mean?" she asked. "Well, I've got a hole in the box, so why don't you come in and I'll put my dick in? Then you can see what it's like, and I'll see how it feels. I know you can't play with my balls, so you can just suck my dick and maybe play with the shaft a little," I suggested.

"Okay." She agreed.

We went upstairs to the room and I took off my shorts and underwear. I was already hard just thinking about my little sister only wearing panties. Cindy sat down on the floor fully clothed and told me to put the box over her.

"This is a dress rehearsal, which means you have to undress completely, except for your panties," I said with an evil look.

"You just want to see me almost naked!" my sister sneered.

“Perhaps… but still…”, I urged.

Cindy left the room without a word. I wasn't sure if she was embarrassed or angry. I didn't even know what to do. Before I could decide, she came back into my room wearing only her panties. Damn, she was hot! I mean, she was so sexy I would have come all over her if I hadn't come so much this week. She realized I liked what I saw because my penis, which had emptied when she suddenly left the room, immediately expanded well beyond its normal size. I laid a towel on the floor and had her sit on it. Then I carefully put the box over her head and asked if everything was okay.

She said everything was fine, so I pushed my hard penis into the hole. She said she couldn't see it, so I pulled it out and got a small flashlight. I handed it to her through the hole and pushed my penis back into the box. The next thing I knew, her beautiful lips were sucking on my rock-hard cock. I started timing myself, and in less than five minutes, I came. I pulled her out and lifted the box. It was covered in semen.

"I think I really came a lot this time," I giggled.

"That's strange. Where did you get all that sperm from? That's more than you ejaculated?" my sister wondered.

"Shit. You look so sexy in your white cotton panties that I just had to ejaculate a huge load," I explained.

She stood up, took the towel, and began wiping my semen off her body. There wasn't much I could do except stand there and stare at her sweet young body. I really wondered if she already had pubic hair and what her firm ass looked like bare, but I didn't dare ask. I guess she knew what I was thinking because, looking right into my face, she pulled off her panties. Then she turned around and bent over to show me her bare ass. All I could do was moan because I wanted to fuck her virgin pussy so badly. Sister or not, she was one I would have loved to fuck. She stood up and turned around again.

"That's what you wanted, isn't it? Do you like it?" she purred.

“Yesssss…”, I groaned.

She grabbed her panties and ran giggling out the door. "You can look, but don't touch..."

"What a fucking temptation!", I thought.

Over the weekend, I contacted a few of my friends and told them I knew where they could get the best blowjob of their lives. I explained that it would cost them 10 cents a minute until they came. I explained how it worked and what times were available. They were instructed to let me know when they were coming and to show me beforehand how much money they had so they wouldn't run out. Despite all my preparations, we could only wait for the clients to call.

Late Sunday, I got a call from a guy on the street. He wanted to make sure it wasn't a man giving the blowjob. Once he knew it was a girl, he gave me a time for Monday. On Monday, he showed up, and in less than three minutes, he'd shot a huge load of cum from his 10 cm long, super-hard, hairless cock. I later found out it was his first blowjob.

On Tuesday, an older guy came in who was curious to see how good a blowjob from a girl in a hidden box would be. He soon found out when his 18 cm hairy cock ejaculated its load in just under ten minutes.

Wednesday passed, and we were beginning to think the whole thing was a waste of time. On Thursday morning, we got a call saying that two brothers wanted to try us out. One was 12 years old and in my sister's class, the other was his older, 18-year-old brother. Luckily, my sister didn't know who she was sucking, otherwise she might have died of embarrassment.

When they were gone and I lifted the box, I found Cindy covered in semen. She said the bigger cock came so hard she couldn't even drink half of it. The smaller one didn't come much, but she liked it better because it was hairless.

By now we were enjoying our little adventure. Many of the boys kept coming back. Even the 16-year-old was often there. He even said the blowjob was the best he'd ever had. Cindy eventually got tired of the semen on her panties and decided to do the blowjobs naked. That made me want to get some more myself.

Over the next month, we did a lot of business. Cindy gave two to five blowjobs a day, some lasting up to 15 minutes. We tried to do them all at roughly the same time so she wouldn't have to wash up so often. Eventually, she needed something to drink under the bed because her mouth was doing so much work.

Some days so many guys ejaculated in her mouth that she did what she could, but then she'd pull the penis out of her lips and lick their balls dry on her naked body. It was funny how covered in cum she was some days.

We were soon earning at least $10 a week. We earned so much that we couldn't even tell our parents because they would have wondered where we got it all. The best part was that my little sister loved all the attention and the many splashes of semen. She enjoyed drinking the semen, but some days there was so much that it covered her entire body.

One day, after we'd had a large group of men, she was covered in more semen than I'd ever seen. When I peeled the packet off her, I noticed her little fingers playing with her pussy. I'd never thought of that. She gave so many guys that pleasure, but she never got any in return. I asked her how I could make it up to her, hoping she'd let me fuck her tender pussy.

Giggling, she said: "Do you want to jerk off on me while I tickle my pussy?"
until I come?"

To clarify my request, I asked: "Do you want to touch yourself? Wouldn't you rather I played with your pussy instead?"

"I like to tease my own pussy. I've been doing it ever since I sucked Nate's big cock. I just want us to masturbate together so I can watch you."
"However you do it," she explained.

The mere thought of her playing with her pussy while I jerked off in front of her made me incredibly hard. I was soon naked, and after a few simple questions, I got into position. Cindy was lying on the floor,
with a pillow for a headrest. Her legs were spread, and her feet were flat on the floor. I looked at her slightly swollen breasts, glistening with all the still-wet semen. My sister's hands were already positioned between her legs. I knelt between them and began stroking my super-erect cock.

My eyes were fixed on her small, young fingers playing with her pussy. She started by rubbing her hairless vulva, pushing her fingers deeper into the cleft. She tried to keep her eyes open, staring at my hands as they stroked my cock and played with my balls. I could have come at any moment, not only from what I was doing, but also from the super-hot show I was watching my 12-year-old sister finger herself. Her fingers moved faster and faster as she handled her female parts harder and harder. Soon she pulled one hand out of her cleft and turned her attention to her clit. She pulled at it and thrashed it around like a tennis ball. I, on the other hand, had stopped jerking off because I was so close to coming that one touch in the wrong place and I would have exploded. Cindy's breathing was heavy and rapid. Her fingers penetrated deeper and deeper into her virgin pussy, while her other hand pulled and pinched her tiny clitoris.

"Mmmm... Mmmm... Mmmm..." moaned Cindy. "Come soon... Come with me, big brother..." she begged.

Damn. I was going to come whether I touched myself or not, so I figured I'd better jerk off more to make the orgasm feel even more exciting. I grabbed the steel rod between my legs and started masturbating harder than ever before.

Cindy saw that I was about to ejaculate and screamed: "Yessss... Do it. Do it now!!! Squirt on my pussy!!!"

I felt the semen make its familiar journey from my glans. Half a dozen hard thrusts, while I watched my sister abuse her own pussy, drove me wild. The first spurt started at her sexy navel and shot up to her chin. Then I redirected my load, and the next four or five hard spurts hit her labia and her fingers as she continued to masturbate.

"Ohhh... Damn... I'm coming..." she screamed as her fingers sucked up my fresh semen and pushed it as far into her pussy as possible. Her fingers made several trips to transport as much of my semen as possible into her pussy. When her pussy was well coated with my semen, her body began to tremble as her fingers alternately rubbed and roughly worked her pussy.

“Damn it… Damn it… Damn it… Here I come again!” she screamed, her whole body jerking.

I couldn't stop and kept milking my cock until every drop of semen flowed from my shaft onto my sister's body. We were both breathing so heavily that we couldn't even hear someone come in. A few minutes later, she went limp and closed her eyes, but she was relaxing. She lay motionless on the floor, only her small breasts rising and falling as she tried to keep breathing. It must have been another ten minutes before we both came to after the best mutual masturbation sessions of our lives. We looked at each other and started laughing. She was covered not only in my wet semen but also in the dried semen of the other guys. I was still holding my limp cock, which was also covered in my semen. "I think we need to shower. Do you want to shower together?" I asked, hoping she would agree. "Okay," she replied sweetly. I helped her up, and we went into the bathroom together. I turned on the water, and we went in. We both got wet before we started cleaning ourselves. She turned to me and leaned back to wash the semen out of her hair. I took the shampoo and worked it into her long hair while she took the bar of soap. "Would you like to lather me up?" she asked, holding out the soap. I gladly took the bar and began washing her back and bottom. I loved the way my hands glided over her young, beautiful ass and my cock got hard again. Then I washed both sides of her legs before she turned to face me. Then I soaped her neck, her breasts, her nipples, her stomach, and finally her semen-soaked pussy. Cindy didn't complain at all. She even purred softly with excitement as I played between her legs.

When I was finished with her body, she took the soap and washed my back and legs before I turned back to her. Then she soaped my neck, chest, stomach, and finally my penis and testicles. The intense attention she gave my penis made me hard again.

"Rub your cock against my soapy belly and breasts until you come. Please..." she begged.

I pulled my cock up and wrapped my arms around my sweet sister. I began to hug her tightly, pressing my body against hers. As I rubbed her naked body, I leaned forward and kissed her beautiful lips. Our kiss quickly became very passionate. I slipped my tongue into her mouth as she did the same with hers. As our tongues melted together, my cock melted with my little sister's naked body. A few minutes later, I shot out my next load of sperm, which effortlessly spread over our bodies.

"Looks like you've squirted all over me again. Here. You'd better be your sister again," giggled Cindy.

I soaped her up, and while she rinsed off, I did the same to myself. We got out of the shower and dried ourselves off. While she dried her hair, I took all the towels to the washing machine and started doing laundry.

When I entered my bedroom, I noticed a strong smell of semen. I grabbed some air freshener and sprayed it before starting to tidy up. I finished the laundry and put everything away before we got dressed. It was a lot of fun being naked near my little sister, especially since she was naked too. We managed to get dressed just before our parents came home.

Summer ended faster than we wanted. Our schedule dwindled, too. One reason was probably that we could only do things at certain times before our parents came home, but the main reason was that the boys were running out of money. Apparently, they were all doing odd jobs in the area to earn money I could give my sister and me for sex. Funny, we'd started the summer looking for odd jobs, but then we ended up starting our own business. All the other boys ended up doing all the work in the neighborhood just to earn money I could give my sister and me.

Cindy grew bigger and eventually she barely fit in the box anymore. We couldn't find another box and she was tired of sucking dicks, so after another successful summer, we broke up. She continued to give me as many blowjobs as I wanted, and we even masturbated together a lot. Unfortunately, I was never allowed to fuck her pussy, but it was okay because we still had fun and made a lot of money on the side.

End
