My name is Jim. I am 19 years old, a sophomore at Duke, and considered by everybody in my class to be the smartest and best student. Sounds good, doesn't it? Well, If I was better looking, a good athlete, or at least more socially adept, it would be, but I am not. I am 5'8", 168 pounds, with disproportionate size organs. For example, my nose is too long, my hands are too big... You get my drift. Since childhood, I liked to read books, play with my computer, and watch documentaries on TV. It was very rare that I ever went outside or played with my classmates during breaks. I've never been to the seashore or a swimming pool.

I have a sister name Pearl. Unlike me, she is a 'normal' one. She is 2 years older, 5'6", 128 pounds, has a cute face, long dark brown hair, and an athletic figure. I like her, though we do not interact that often. She likes to get out with friends of both sexes, chat, gossip, and have a good time. When she is home, Pearl and I meet at dinner and have little talk about school. On multiple occasions, she came to my room, needing help with homework or preparing for her exams. Usually, it took me little time to understand what she couldn't, and I explained everything in simple terms. She appreciated it and thanked me in front of our parents. In her mind, I was an odd duck. A nice, useful odd duck.

What Pearl didn't know was that I saw her in my dreams and fantasies. I masturbated, seeing her naked, begging me to use her body for my pleasure. I admit that once when she was out, I even entered her room and checked her underwear drawers. I touched her soft C-cup bras, imagining her perky breasts inside. I also sniffed her panties, thinking it had a faint odor of her vulva. It might have been only my imagination, but the effect on me was significant: I got an immediate erection and jacked off in our bathroom.

My parents were a typical blue collar family with modest jobs. Our house was a 2-floor type, but was relatively small with 3 bedrooms, 2 bathrooms, and no air conditioner. It was OK during 6 months of the year, but during hot days of summer, it was tough to tolerate. The way I dealt with it was by leaving the window open and operating the small table fan toward me. It wasn't ideal, but I got used to it.

Lately, I noticed stains by the window, and I got the impression that small things like my stapler, a pair of scissors, an eraser, and even candies have disappeared from my room. Somebody, or something, was likely entering through the open window when I wasn't in the room and stealing stuff! I doubted it was another child: My room was on the second floor, and though a tree reached the window, it was not easy to climb it. Was it a cat? A raccoon? Something else?

Nothing that disappeared was of value, but I was curious what it could be. With my money, I purchased a miniature spying camera and decided to install it and investigate who the thief was. I placed the camera on the wall above the door. It gave a nice view of the whole room, including the window, my bed, and my desk. I have not operated it yet.

The same evening, at dinner, Mom smiled at me, "Jimmy, your 20th birthday is a week from now. What do you want for your birthday?"

"I have no idea, Mom. Why don't you put $50 in my account, and I'll buy something I need when I find out?"

She mumbled, "Honey, you are so predictable. It is frustrating that you are always by yourself. We cannot buy you something special and see you happy with it."

Pearl blurted, "Mom, I have an idea. I'll take him with me to a bar I often go to. They know me and never check ID. This time I won't bring along my friends, and Jimmy will feel comfortable."

I started protesting, but Pearl insisted I go there with her. I knew my sister; whenever she set her mind to a project, she never changed her mind, so I reluctantly gave in. I told myself, 'If there was nobody else we knew, I wouldn't embarrass myself, so seeing the inside of a bar the first time was something I could tolerate.'

Friday after class, I shaved, showered, and put on a clean shirt and khakis. I was scared shit to screw up and embarrass my sister and myself. I knocked on Pearl's door and told her I'd rather stay home. She blurted, "No, you don't. I canceled all my other plans for you, and by hook or by crook we are going. We will stay there for at least an hour. After that, if you choose to return home, we'll do it." And that was it. In the last minute, I remembered to leave my window open and set up the video camera.

We left home. On the way, she attempted to cheer me up, saying I'd like it there. But when we entered, I felt trapped. It was still early, and we found a corner place to sit.

Pearl said, "Wait here, I'll bring us something to drink."

While she was gone, I looked at the noisy place, not understanding why people found this place interesting. There was a pool table and a dartboard. Certain guys played cards, but overall it was an uninspiring, smoky joint...

Pearl came back with 2 glasses. She handed me one and smiled, "It's a simple cocktail. Try. I think you'll like it."

I sipped a little. It tasted sweet and delicious. I didn't feel the alcohol at all. I told Pearl I liked it, and she laughed, "I told you. You are too stubborn. It's time to get out of your homey cage and see the world around you."

I continued drinking the tasty stuff, and our chat moved to Pearl's studies. She said it was becoming more difficult lately, and she might need my help again. I grinned, "You were nice to me on my birthday, so I'll be happy to help."

Pretty soon, my glass was empty. The bar became crowded and noisier, but for some reason, I felt good. Much better than before. Pearl went to bring us another drink, and came back chuckling, "Would you like to try dancing?" There were 3 other couples moving on the floor, but I'd never danced and felt my feet were heavy. I declined and said, "I prefer to sit, drink, and talk."

Out of the blue, Pearl asked, "Jimmy, are you gay?"

I almost fell from my chair. "Of course not. Why would you think it?"

"Because I have never heard you talk about girls."

I blushed, "Right now I care more about school. When time comes, I'll think about it."

Pearl's eyes brightened, "You have no idea what you are missing."

I sipped my cocktail and mumbled, "What AM I missing?"

"These days, I go out with Roger. So far, he is the best I've had in a long time."

"What's so good about him? He is tall, skinny, has pimples, and dumb..."

She giggled, "You exaggerate, but even if you were right, he has one BIG, let me rephrase it, LONG, advantage..."

"What do you mean?"

"Jimmy, you are still a virgin and have no clue about the pleasant things in life. When hard, Roger's dick is 8" long and thick. He is the only one who could make me orgasm during sex."

"Is 8" considered long?"

"Honey, are you kidding me? Haven't you read anything about sex? Average man's dick is 5 and something inches. 8" is every man's dream and a woman's pot of gold."

I began laughing. She stared at me quizzically. I said, "Mine is 9.5" when erect."

She blurted, "Stop joking. I am serious. Roger's penis is huge, and all my girlfriends are jealous of the way I feel after spending time with him."

I started feeling lightheaded, but it was a pleasant one, "I was not kidding. My cock is almost 10" when I jack off."

Her eyes widened, "You ARE serious, aren't you?"

"Yes, I am. But until now it was a burden. At rest, it's about 6.5", and frequently I have to readjust it in my underwear."

"I don't believe you. You are just trying to get my attention."

"Never mind, let's forget about it. So you didn't care about Roger's drawbacks and elected to date him purely for the sex?"

"Obviously you haven't had sexual intercourse that you talk like that. The most pleasurable feeling in the world is a good climax."

My head started spinning, and I stuttered, "Pearl, I draank toooo much. I feeel dizzy. Leeet's go hoome."

She laughed, but helped me stand up. Soon we were on our way back home.

I recall reaching my room and Pearl telling me I needed to undress before going to sleep. Then everything turned dark.

I woke up in the morning remembering having a wet dream: I was watching a movie, and out of the screen, Scarlett Johansson came toward me and began sucking my organ. I wanted to ask her how she entered my room, I but couldn't talk. She gave me a great BJ and I came in her mouth.

I remained in bed for another 20 minutes, trying to recall last night's events. Much of it was blank. I needed to pee, but my member felt sore. I inspected it; it had a couple of sperm stains and red marks. What the hell? My first impression was that I developed some lesions on my rod, but after noticing I could remove the red marks with my fingers, it turned out to be... lipstick. WTF?... I had no clue what was going on.

I went to pee, freshened up, and checked my desk. Nothing was missing. Whoever stole my stuff did not attempt to do it when we were in the bar. Just in case, I looked at the recording. During the time we were out, a cat once sat on the window's ledge but never got in. A couple of crows flew inside and left minutes later. Then I saw Pearl holding me and telling me to undress before going to sleep. I just fell unconscious on the bed with my clothes on. She closed my door and started taking off my shirt. I seemed to be out and didn't help. Then she unzipped my fly and pulled my pants from under me. On the screen, I noticed her checking the bulge in my briefs. She talked to me and touched me, but I was completely out. She hesitated, but then lowered my briefs and gazed at my resting cock. She gasped. I was snoring. She touched my organ and then took it in her palm. I was snoring loudly. She whispered, "Jimmy, you weren't lying. Your dick is marvelous. Do you mind if I see how big it becomes when hard?"

My respiration and snoring didn't change. She massaged my prick, and slowly it began engorging. Pearl mumbled, "Bro, this is a monster. I wonder how it will feel in my mouth..." Next, her lips spread widely and engulfed the helmet. Her red lips started sucking my dick. She attempted to pull into her oral cavity as much as possible, but 3" remained outside the whole time. She bobbed her head on it for several minutes until I saw those 3" spasming in her mouth, and I knew I was ejaculating... Dear god, my sister blew me when I was drunk...

I wasn't sure whether I should feel upset or happy. She took advantage of my helpless situation, yet watching the recording made me horny as hell, and I masturbated watching the recording over and over again.

At dinner, Pearl's behavior toward me changed. Before, she used to chat with everyone around the table about her friends and social stuff. And now her eyes seemed to be sneaking glimpses in my direction. Mom asked her how it went in the bar the night before. Pearl glanced at me, waiting for me to answer. My mind was full of ideas about how to answer, but after a short hesitation, I mumbled, "It was OK. Different, but OK." As I talked, I watched Pearl taking a deep breath, seemingly relieved I didn't know what REALLY happened.

When the dinner was over, she came to my room and sat on my bed's edge, "Jimmy, you must have been under the influence, so you cannot remember much. I asked you why you haven't had a girlfriend yet."

I smiled, "Sis, what are you getting at?"

"You are a nerd, but you are smart, have a great future, and according to YOU, you have a big dick. I know many girls who would consider you a catch."

I stared at her eyes, "Does 'many girls' include you?"

Pearl stuttered, "Why dooo you aask?"

"Because last night you mentioned your main reason to date Roger was his big penis."

"Long, thick, juicy cock is a big advantage, that's for sure."

I smirked, "So if my organ is bigger than your boyfriend's, I'll have a chance?"

"Jimmy, you are my little brother. How can you even think about it?"

"Do you like sucking a big cock?"

"Your question is crossing the line, but since we talked about the subject yesterday, I'll tell you I love it."

"Is swallowing man's seed part of your ritual?"

"Why are you so fixated on my blow jobs?"

"Because I think you like milking long hard cocks and love swallowing seed."

"How would YOU know?"

"Isn't that the reason you sucked my dick last night?"

Pearl's face turned pale, "What's wrong with you? You were too drunk to know what was going on, and I was forced to undress you, but after that, I covered you with the blanket and left the room. By the way, your snoring was too loud."

I sat by her side and operated the remote control to watch last night's fun once more. She saw herself bringing me inside and undressing me, and realized what was coming next. Pearl attempted to flee the room, but I stopped her and forced her to sit still and watch the whole thing.

When it was over, I eyed her, "Sis, you seem to crave big cocks, aren't you?"

Her head was down, and she kept silent.

I asked softly, "What should I do with the new revelation?"

She whispered, "Please don't tell our parents."

"Why not? Liking to give oral may be hereditary. Perhaps they ought to know you inherited it from Mom."

"Please, Jimmy, don't do it to me. I'll clean your room for a full month if you destroy the evidence."

"My room does not get very dirty. I keep it clean myself."

"What do you want to keep quiet and never mention it to anybody?"

"Good question. I don't get out much, but my testosterone levels are high, like most young guys. I haven't had a girlfriend and wish to see what breasts look like in real life."

She grinned, "Now you are talking. I have a few girlfriends who would be happy to date you once I tell them what a beast you have in your pants."

"Wrong direction. I am not interested in other girls. I wish to see YOUR tits."

"Why? They are normal size and shape. You tell me what size you want, and I'll find you the right girl."

"Pearl, for quite some time now, I have been obsessed with your body. I wish to see YOUR naked body!"

She smiled, "Really? Are you a pervert?"

"Sis, it's amazing to hear this question from the sister who just sucked me to a happy ending."

She blushed, "In the beginning, I was tempted to verify what you told me in the bar. But when I saw how long it was when flaccid, I had to see the size when fully grown..."

I smirked, "And later you milked it to ascertain the taste was not poisonous, right?"

She whined, "Why are you torturing me? Didn't you enjoy it too?"

"Unfortunately, I was completely out when you capitalized on my prick. However, this morning, after seeing the recording, I became very aroused and jacked off watching the movie. Now take off your clothes and stand before me in the nude."

"Earlier you said you only wished to see my breasts."

"I changed my mind."

"Please, don't make me do it."

"I do not see why. You saw my privates, and I wish to see yours. I think it's very fair."

She sighed and began undressing. First came off her blouse, displaying a pink silky bra, nicely covering her C cup tits. Next, she lowered her skirt, and the matching pink panties appeared. Pearl looked into my eyes, hoping I'd spare her from removing the rest. I didn't budge. She reluctantly unclasped her bra, and it landed on the floor, exposing gorgeous, perky tits with large areolas and dark, protruding nipples.

I licked my dry lips, and my pecker jolted and began ascending in my shorts. She noticed my reaction and smiled, "Bro, you are getting too excited. Shall I stop here?"

"Of course not. Go on!"

Pearl slowly lowered her panties while her eyes focused on mine. I ogled her bare vulva with the swollen folds, and my breathing stopped. My cock generated a massive tent in my pants. I adjusted it and continued watching the first female cunt I've ever seen. I craved to touch it. Well, the truth was that I wanted MUCH more than just to touch it...

I found my voice again and blurted, "Now come here and take care of the problem your breathtaking figure caused me."

Pearl eyed me, "Are you telling me you want me to suck you again?!..."

"In the movie, you looked like you enjoyed it, so go ahead. I wish to see and feel you doing it again, this time live."

"Jimmy, I love to give oral to a big dick, but isn't it better you experience it with one of my girlfriends?"

"Pearl, I told you already; I want you and nobody else. I wish to feel YOUR lips around my schlong."

She had a strange smile, "If you insist..."

I removed my pants and underwear, revealing my erect pole, which stood up like a proud flag, pointing toward the ceiling. Pearl's eyes brightened. She came to where I stood, pushed me gently to sit on the bed, and parted my legs. Her palm tenderly caressed my steely hard member. She murmured, "Bro, you have the most awesome monster I've ever seen. It's so huge, veiny, and velvety on the outside, that I am very tempted to do just what you asked me to do..."

I remained silent, and my eyes were mesmerized by her working on my tumescent organ. Next, she bent her head and kissed the tip. It jerked mildly. She chuckled, "I think it likes me already."

Subsequently, her lips opened wide, and enveloped the spongy head. Her tongue licked it. I gasped and felt my prick grow another inch.

Then, her mouth moved to slowly encompass as much as she could into her small mouth. I was hypnotized by her uncanny ability to take in so much. Once only 2" were visible, she started bobbing on it. My arousal shot up, and I knew I wouldn't be able to hold for long. My dream was coming true!...

I held the back of her head with both my large palms and erupted down her throat like a raging volcano. Pearl didn't try to retreat. I saw her throat working overtime, swallowing expertly everything as it came. When my stream diminished, she licked the stains, and I noticed her right hand was playing with her cunt.

"Sis, is it what I think it is? Did you get horny sucking me?"

Her face flushed, "I told you I love giving BJ to big cocks. Yes, I got aroused..."

"Excellent, because the next thing on my agenda is to fuck you."

"Jimmy, please, not that. Yes, your organ is magnificent and I am highly aroused, but we are brother and sister. What I did now was improper, but having sex is taboo. An incest. I thought of calling Roger and have HIM grind me toward a blissful orgasm..."

"Pearl, you were wrong. I have never had sex before, and I desire your terrific body. Ignore the BS you call incest. There's nobody here to complain about it. However, I promise to do it only once. I want to feel your pussy and experience sex with you. After that, I'll never bother you again."

She stared unabashedly at my stiffening member and mumbled, "So one time only?..."

I raised my right hand, "Scout's honor."

She lay supine on my bed, parted her legs, and glanced at me as I removed my tops. I knelt between her thighs, aimed the large helmet at her snatch, and gradually advanced inside. She was soaked down there, but her tunnel was very tight. I knew that with my thicker than usual pecker, the inside would feel narrow, but it was even tighter than I thought. I gingerly progressed, feeling Pearl's respiration turn shallow and her heart rate jump up.

I heard her mutter, "Oh god, I've never felt that full in my life..."

When her butt cheeks met my heavy sack, the tip of my penis hit her cervix. I waited a minute, letting her pussy walls accommodate my girth and then slowly I started pounding her vagina. The friction was very pleasant. I never thought it would feel like that... Fortunately, I climaxed not long ago, so I could control my actions better.

I continued at a slow pace, but increased the power. All of a sudden, Pearl shuddered and began whimpering. Her fingers pinched my waist, pulling me deeper into her body. I accelerated my rhythm, plowing her pussy relentlessly. Her shuddering turned into uncontrolled convulsing, and she began screaming half sentences, "My lord... It's pure heaven... I am dying..."

I watched her wildly bouncing tits and hissed at her, "No sis, you are not dying yet. I am not done using your fantastic body!"

Next, I cupped both breasts and massaged them. She cried. I loved feeling her hard nipples, and gently pinched them. Her cries turned louder. My own arousal was reaching a high level. I moved my right hand from her firm tit to her tiny clitoris and tweaked it. Her body jumped in the air, and she started shouting like a pig being slaughtered.

I was afraid somebody would come to see what was happening. There was only one thing I could do: I leaned on her body and French kissed her, muffling her noisy sounds. As my lips latched to her soft ones, my tongue invaded her mouth and explored her sweet oral cavity. I felt a faint taste of my sperm...

I continued for another 5 minutes before ejaculating several jets of slimy spunk deep in her cunt. I was spent, but... extremely happy. The experience was something else. I knew it was supposed to pleasure me, yet there was no way to compare it to masturbation. It was absolutely amazing!!!

Pearl didn't move for almost half an hour. Then she opened her eyes and stared at me for a long time. I was too tired to guess what she was thinking about. After a couple of minutes, that felt like an hour, she said, "Jimmy, and to think it was your FIRST sexual encounter... You are a sex god! Never before I have reached so high during an orgasm. It was wonderful!"

I smiled, "Good, so now I do not have to feel guilty that I took advantage of your body. I regret telling you that I'll destroy your movie. Now that you are free to return to your Roger, I hoped I could still relive our escapade, watching you BJ me, and jack off happily..."

Pearl caressed my body and mumbled, "Jimmy, a promise is a promise. Destroy the recording. But in return, if you are up to it, we can discuss continuing our sexual bliss..."​
