From A Bitch To A Perfect Sister

"Sandra, it is the same material you went through 2 years ago, and you got an A. It will take you only half an hour. My exam is on Thursday, and Dad will chastise me if I fail."

"Fuck off. Don't you see I am busy playing a video game with Jill? Find a classmate who'll do it with you."

"Please, you know the stuff, and you are here. Can't you stop your stupid game for half an hour?"

"Mike, you are the most annoying brother ever. Not interested. Now get out of my room."

I exited, called Lance, and sat with him for 4.5 hours, preparing for the exam. My priority was to pass the exam, which I did, scoring a B-. However, I did not forget the way my older sister talked to me in front of her best friend and vowed to vindicate the bitch. It wasn't the first time she treated me like dirt, but it was the last straw.

...

My sister, Sandra, was older than me by 2 years. Growing up, I admired her. She was a straight-A student who, surprisingly, studied very little. She had a great memory, and once she read an article or heard something in class, she remembered it. Throughout high school and later in college, she was a cheerleader for the football team. Sandra had an exotic, pretty face, dark, shoulder-high wavy hair, a straight nose, and an athletic body.

Jill, who was her best friend for years, was the exact opposite of her: She was shorter, had long blonde hair, blue eyes, angelic-type beauty, and a massive rack. Jill was quieter, polite, and smiled a lot.

When I started my senior year in high school, I turned 18. I already knew my future direction: Engineering. I was very good with my hands and loved to design and build stuff. At home, I was the unofficial handyman, and rarely we needed somebody else to fix our plumbing, electrical, or structural problems.

However, in order to get accepted to ASU, I had to get decent scores in subjects I hated and was terrible at, like social studies, which was the subject of our exam.

...

I was debating how to accomplish my revenge plan. It wasn't easy: Sandra was a great student in college, looked amazing, and did not use drugs. Her door was always closed, and there was never loud music coming from her room. She could do no wrong. What else would parents ask from a perfect girl, who god gave her everything? She was loved by Mom and admired by our conservative Dad.

I pontificated on how to proceed and then came up with an idea: I'd install a small video camera with audio capabilities in her room. The likelihood of getting something incriminating was low, but I might get to see her in a bra and panties and, if lucky, even naked...

Cameras like the ones I was looking for were very cheap. The cost of a reliable device was $20-$40. I bought 2 of them. One time, when Sandra was out, I installed the 2 tiny devices. One I put on a shelf between 2 books, and the other I mounted on top of the standalone lamp by the door. The 2 devices recorded everything to the cloud, and I could monitor the room live if I wanted to do it.

The first 2 days were unimpressive. Except for 2 seconds of watching Sandra preparing to shower and putting on a robe on top of her lacy underwear, there was nothing interesting.

Then the weekend came. Every weekend, Jill arrived at our house in the morning. Later, the two girls would go out together. Often, Jill slept in Sandra's room on Saturday and left on Sunday night. I envied them - I never had such good friends.

Since I had nothing better to do on Saturday, I chose to stay in my room and watch. The main reason was to ogle Jill. Even fully clothed, her huge tits were fun to watch and easy on the eyes. I might even masturbate seeing her laughing with her mammaries jiggling...

Sandra was in the bathroom when Jill knocked on the front door. I opened it, and she smiled, "Mike, you look nice today. Are you going somewhere?"

I blushed, "I thought I'd stay here for a while."

Mom greeted Jill, "I love your floral blouse. It looks good on you. My husband and I eat breakfast. Do you care to join us?"

As Mom was talking, Sandra exited the bathroom door. Jill glanced at Sandra quizzingly. Sandra smiled, "Mom, that's OK. We'll manage."

The 2 girls entered Sandra's room and closed the door behind them. I did the same in my room and watched them live on my computer.

Sandra chuckled, "Honey, why didn't you tell Mom you were about to eat breakfast in my room?"

Jill mumbled, "Sandra, you are so naughty. I don't know why I love you."

"Because you were destined to be my sub, and you like it, don't you?"

Jill whispered, "Yees..."

"Girl, I agree with Mom; the blouse looks good on you. Almost as good as with nothing on. It's time for breakfast."

Sandra sat on her bed's edge and gazed at Jill. To my amazement, Jill unbuttoned her blouse and unclasped her bra. Her twin mountains burst out and swayed mildly. I gasped. I remembered ogling nude pictures of Kate Upton. Jill's breasts were the same size or even slightly bigger and stood firmly high on her chest. The pink areolas were large as well, and in the middle were 2 pointy nipples. My penis began swelling.

I continued watching and saw Jill approaching Sandra and lifting her skirt. Sandra had no panties on! Her shaved pussy was on full display before my eyes.

Jill knelt before my sister, spread her thighs, and started lapping on her exposed cunt. Sandra caressed Jill's hair and said, "Good girl. Don't you prefer this breakfast?"

"yees..."

"I like to see you munching on my coochie. Your tongue became a real expert."

Next, Sandra's hand cupped Jill's boob and kneaded it, "Your tits seem to continue growing. Is it already DD?"

Jill lifted her face and murmured, "D-cup bras are becoming too small." She continued licking the moist labia.

Sandra blurted, "Bitch, I love how you do it. After a week of drought, I am very horny. I am close to cumming, and I'll likely squirt. You know I like you to drink it all. No spilling this time! clear?"

"Yees, ma'am."

A minute later, Sandra's torso tensed, her eyes closed, her head extended backward, and she shuddered while whimpering softly. Jill stopped lapping, and her mouth latched to Sandra's opening, swallowing her juices. It all ended in 30 seconds.

Jill licked Sandra's cunt clean and remained kneeling before Sandra with her face stained. When Sandra recovered, she fondled Jill's cheek, smiled, and said, "Darling, you are doing better every day. You deserve your prize. Undress and lay on the bed."

Jill removed her skirt and panties. Her flat feminine tummy and dirty blonde landing strip were gorgeous. My prick was now at full mast, waiting to see what came next.

Sandra undressed and looked at herself in the mirror. Her figure was so different than Jill's, yet very sexy as well: Her breasts were much smaller, I'd say B+ or C, but very perky with dark, stiff nipples. Her tummy was more muscular than Jill's, and her shaved legs longer.

Damn! The view of my naked sister and her friend would appear in my wet dreams and serve in my future masturbations!...

Subsequently, Sandra pulled from the drawer by the bed a 6" vibrator. She winked at Jill, "I didn't like the previous one. It was too small for you. This is a real man's size. Once I am done with you, you better thank me nicely!"

Sandra operated the vibrator at a slow speed and touched Jill's snatch with it. Jill shivered and moaned. Sandra shifted the speed up, and her fingers massaged Jill's humongous breast. She groaned louder.

Sandra smirked, "Honey, would you like it to be Bart?"

Jill mumbled, "Not Baart, he iis a jerk..."

"But he has an 8" cock. I know; I fucked him once."

"Noot hiim,,,"

"So, who would you wish to ravage you?"

"I doon't knoow."

"Girl, I can arrange for you any guy you wish."

"I caan't thiink now..."

"You better tell me or I won't let you cum!"

"...Joosh or... Mike..."

"Are you kidding? They are nerds!"

"... they aare nice, non puushy, and they seee me as a person aaand not just seeex object..."

Sandra laughed, "I am sure my moron brother would have loved to hear it. I think he is handsome but too annoying to be able to think of as a lover."

Jill didn't answer, and her moans intensified. Sandra increased the vibrator's pace and blurted, "Bitch, it's time to climax!" Next, the vibrator's buzz became much louder, and Sandra's thumb flipped Jill's clitoris from side to side. Jill's body trembled, and she began to cry. Sandra moved on the bed and sat on Jill's face, drowning her noises.

A short time later, everything was over. The girls dressed up, and Jill went to the bathroom to wash her face. They played 2 video games and later got out of the house.

I checked the equipment in Sandra's room. Everything worked fine and the morning act was easily retrievable on my computer. I watched Jill's tits and her eating Sandra's pussy and masturbated twice. The whole thing was unexpected and highly erotic.

I was ready to see what the following day would bring.

...

Jill stayed the night. They entered the bed naked and covered themselves with a thin blanket. When I saw the light go off, I went to sleep too.

I woke up at 7 am and reconnected my computer to the live cameras. They were still under the covers, asleep. I freshened up and returned to my room 20 minutes later. There was some action in their room. Sandra was on her back with her eyes closed. Jill's head was not seen, and the blanket on Sandra's body moved rhythmically back and forth.

Seconds later, the blanket was thrown on the floor, and I saw Jill having a strap-on between Sandra's legs, fucking her with it! Jill whispered, "Mistress, do you want me to be Bart for you? To fuck you silly with my horse-size cock?"

Sandra groaned and mumbled, "Yes, and when you cum in my cunt I want you to lick it."

"Of course, milady."

Jill pounded Sandra and sucked on her tits, bringing my sister to a wonderful orgasm. To prevent her mouth from making too much noise, Sandra sucked on her thumb, muffling her cries. I couldn't hold it and ejaculated in my briefs...

The whole family and Jill ate breakfast together. The girls behaved as if nothing unusual happened. I watched them, thinking about the events of the last 24 hours, undressing them with my eyes.

Jill looked at me and smiled. However, Sandra smirked, "Mikey, you stare at us as if you've never seen pretty girls before. Unfortunately for you, both of us are out of your league."

I smiled, "Sandra, I know that deep down you love me, and I am sure you'll prove it very soon."

She laughed, "Really?!..." I just grinned.

...

Monday afternoon, I knocked on Sandra's door. She recognized my knock and yelled, "You have your own room; stay there, and don't bug me."

I opened her door and said calmly, "After dinner, I plan to show Mom and Pop an interesting video. I thought you might wish to watch it first and give me your opinion about it."

"Why would I care? Is it something about fixing the sink or shining the car?"

"As I said, I highly recommend you see it first. When our parents see it, it will be too late..."

"OK, idiot. I have no idea why I listen to you. Why the hell would I care about your stupid interests?!..."

I didn't bother answering. I let her sit on my chair and began displaying her act with Jill. Within a minute, her face turned paler than the wall. She shouted, "Pervert! Voyeur! Whatever you did is illegal. I'll notify the police."

I smiled lovingly, "Sis, you may be right. However, I installed cameras in every room to make sure thieves do not steal our stuff when we travel. In any case, when Dad watch the video, I think that he will start seeing you differently. The All American Girl he raised is a lesbo and a Dom. Mom will be devastated, and Dad will disown you. Your perfect reputation will be gone in an instant. Since you have nothing to say to me, I'll see you at dinner. And by the way, the audio-visual recording is on the cloud and in 3 separate folders. The clip you saw is the only one on THIS computer, so if this file or the whole computer is gone, the copies will be sent to Mom and Dad, Jill's parents, my friends at school, and 2 of your favorite teachers in college." I stood up and pointed at the door, "You can leave now."

Sandra smiled sweetly, "OK, jerk, you made your point. You delete all the files, remove the cameras, and do not mention anything to anybody. In return, I'll help you anytime you ask for it."

I laughed, "I don't think so. Our parents adore their perfect goody two shoes and always reprimand me for not being like you. I gave up on your future help when you humiliated me in front of Jill. I'd love to see Dad watching his deviant naked daughter having sex acts with another girl. As I said, leave my room and close the door behind you."

Suddenly, it occurred to Sandra I was serious, and she panicked, "Mike, do you hate me so much you wish to ruin my life?"

"Not really. But the ONLY way I'll keep the data secret is if you obey all my commands from now on. No refusal, no discussion, and no questions. Basically, you'll be my slave until I am satisfied you learned your lesson."

She begged, "Mike, I am sorry for treating you badly, and I am willing to apologize before anybody you want. Please, don't do it to me."

"Sandra, perhaps you need to clean your ears better. You do what I want when I want it for as long as I want it. No negotiations; take it or leave the room right now."

She grinned, "So if I am your slave, what would you like me to do? Clean your room? Do your laundry?"

"You are not even close. Undress!"

She looked at me stunned, "Whaat?..."

"You heard me. Remove all your clothes. I want you naked in front of me."

"Are you nuts?!"

I stood up, "I am tired. Go to your room. I am going to take a shower. We'll meet at dinnertime."

"Mikey, Pleeease..."

"Sandra, fuck off from my room, or I'll drag you out myself."

She began crying. I wasn't sure if her tears were genuine or not, but I couldn't care less. I pulled new underwear from my drawers and opened my door to walk out. She stopped me, "OK, I'll do it. You saw me naked in your filthy video anyway."

I sat on the edge of my bed and glanced at her.

Sandra removed her blouse, exposing a silky soft pink bra. Then she lowered her skirt. She had on matching low-cut pink panties. Her body was amazing. My pecker stirred, and a tent started growing in my pants. She noticed it and chuckled, "I think that should be enough. Your small cock already reacts. If I continue, you may have a heart attack."

"Take off everything. NOW!"

She unclasped her bra, and the marvelous tits I watched on the video appeared before my eyes with all their glory. I blurted, "Nice! Now, the panties."

She lowered the panties gingerly and stood naked, leaning on the wall. She smirked, "Little brother, are you happy now that you saw me without any clothes?"

"Not yet. This was only the beginning. Come here, unzip my fly, and suck my cock."

"Mikey, you are crossing the line. It's enough. You got me naked, ogled my tits, and watched my bald cunt. Everything else is out of the question."

I stood up again, took my clean underwear, and opened the bathroom door. She hid behind my door and shouted, "Come back. I'll do it."

I returned to my room, sat again on the bed's edge, and stared at her eyes coldly. She approached me and gingerly unzipped my pants. I planned everything in advance and did not wear briefs. As my erect cock got free, it jolted forward and up and hit her on the chin. She looked at it, and her breath stopped, "God, it is not THAT small..."

"Suck it, bitch! And remember that in case you are intent on harming my pole or if it's not a world-shattering blowjob, everybody will enjoy your world-class sex act with Jill."

She knelt before me, leaned toward my groin, sniffed my organ, and licked the tip. She murmured, "Not bad."

"I said suck it, slut!"

Sandra parted her full lips and took 1/3 into her mouth. Her lips advanced gingerly on my member until only 1" remained outside. She began bobbing me, and then I felt her palm caressing my ball sack. My fingers found her tits and gently massaged them. Her respiration and pulse accelerated.

"Spread your knees!"

She continued sucking me, and her knees parted. I used my left leg to remove my slip-on Skechers from my right leg and rubbed my big toe on her cunt. It was soaked! When she felt my leg, she gasped and stopped sucking, but seconds later her speed went up. I felt my orgasm pending. My fingers pinched her nipples, and my big toe pressed hard against her swollen clitty. All of a sudden, her body quivered violently. My right hand moved from her nipple and pulled the back of her head into me as I erupted in her throat. She gagged a little but recovered quickly to successfully swallow my spunk.

When my cock started deflating, I let her mouth off my rod and ordered her to clean it with her tongue. She complied.

After she completed her task, I looked at my watch. It was half an hour before dinner. I blurted, "You did your first assignment well. We'll be eating soon. During the meal, your bitchy attitude toward me will gradually change. If Mom or Dad are surprised by it, find a good reason, but from now on, you like and even admire me."

She mumbled, "OK."

I stared her down, "What did you say?!"

"Yes, sir..."

"Much better. Before you go to sleep, knock on my door again, and I'll tell you what comes next. Clear?"

"Yees... sir."

...

During the dinner, everybody was quiet, so there was no need to show new affection between Sandra and me.

At 10 pm, my sister arrived as told. I smiled at her, "Sis, I hate my alarm clock. It's very noisy. I guess I'll still use it on Tuesdays and Thursdays. However, on Mondays, Wednesdays, and Fridays, you leave after me, so I came up with a better waking up method. On these 3 days, at 7 am, you'll enter quietly, lift the blanket, see my morning woodie, and suck it to a happy ending. Understood?"

"Buut, it meeans I have to waake up much eaarlier..."

"That is correct."

"Isn't it better if I I use MY money to buy you a quieter alarm clock?"

"No. I like my suggestion better. It doesn't make any noise, and at the same time it solves my woodie issue."

Sandra lowered her head and did not speak.

"Undress!"

"Why? I sucked your dick a few hours ago."

"Yes, you did. And now I feel like fucking your pussy."

"Cumming once a day is not enough?"

"Of course not. Sometimes, I masturbate 3 times a day. Watching you and Jill going at it, I orgasmed 5 times."

She sighed and undressed. My organ hardened quickly. "On the bed and spread your legs for me."

She did as instructed, shut her eyes, and tightened her lips. Her method of dealing with my commands was to play dead. I chose to play her game and see if I could win. Otherwise, I'd change my tactics. I moved between her legs, touched her labia lightly with my left, and kneaded her tit with my right. I heard soft moans through her tightly closed mouth. I inserted a forefinger into her vagina and probed it. Sandra squirmed. I sucked on her nipple and felt my forefinger becoming wetter. While she wouldn't admit to it, the bitch was becoming aroused. I inserted a second finger inside her pussy and rubbed the front wall. Sandra opened her mouth, and her breathing became heavier. Her groans increased.

I leaned forward and kissed her lips gently. She trembled and closed her mouth. Next, I directed my cock into her entrance and penetrated about an inch inside as my finger began playing with her clitoris. Sandra opened her mouth again and moaned louder. I kissed her lips again. This time, her lips stayed open, and I invaded her mouth with my tongue. She groaned into my mouth as I French kissed her.

I disengaged from her lips and whispered, "Much better, slut. It's time to fuck your tight cunt." Then I shoved my hard penis to the hilt and started plowing her moist pussy. I kept a steady, relatively slow speed, not wanting to climax too early. However, Sandra was very horny, and after 5 minutes, her body tensed, and she whimpered like a baby, pinching my sides and trying to pull me deeper into her body.
