Jack and Jamie were normal brother and sister. Just so you'll know what they look like Jack is 6'1 and has a strong build and a little chub to cover the muscle so he wasn't totally toned with a 7'5 inch penis. Jamie was 5'3 with 24C breasts. They had the normal brother-sister relationship, so they never paid more attention to one another than siblings should. Jack is in his sophomore year and Jamie is in her freshmen year.
Normally their groups of friends were quite different. But as they entered high school they were changing rapidly. It’s the first day of the school year and Jamie gets up at 5 she grabs a pair of clothes then hops in the shower and gets ready after. Jack gets up at 6 takes a shower and goes to the bus stop where her sister is already at. For jack it’s the typical first day of school, he hangs with his friends gets his schedule and such. This is up until lunch when he’s sees his sister sitting with a group of his druggie friends (not all his friends were stoner's just this portion). Seeing as she usually didn't hang out with people like this at the house he was surprised and confused but he walked past said hi to them and went to sit down with his best friends at another table. Jamie didn't notice it was him and didn't look back she just figured it was some random person she didn't know. Jack let it go for now so he doesn't seem unusually weird to his friends. The rest of his day was normal. When he got home he had his friends over to play some video games until 7. Then they left and he went to his room to get on his computer. Later he looked at some porn and masturbated as he usually does at night. , And went to bed an hour later. The next day at school he is walking down the hall and hears his sister’s voice ahead of him and sees her next to the drinking fountain with some people out of the corner of his eye. So he began walking toward them to talk to (he thought his friends and his sister) but then he realized it was a couple of her girlfriends that he'd seen before. Instead he pretended that he intended to get a drink. He acted like he drank then walked off feeling reassured that she wasn't with his D (= stoner friends) anymore. At lunch he saw her with a couple of her friends at a table so he decided that things were normal and he stopped keeping tabs on her.
It was about three weeks later at a small party at his friend’s house when something totally unexpected happened. He arrived after she did with his D friends. So he sat next to his friend Zach to watch the movie that 15 people had come over to watch. It was Zach's house and he had a larger screen and projector. So he invited 15 of his friends over for a small smoke drink and movie. He heard dimly people on the couch perpendicular to him playing truth or dare. And Jamie chose dare. She was dared to take her clothes off besides her socks then stand up and twirl.
She was a bit drunk so she did it. Jack looked over amazed at the body of the girl that he didn't know was his sister. His jaw dropped as he grabbed for his camera and flashed a picture. No one even noticed the flashes; he had taken about 5 pictures some of her front sides and back. When she puts her clothes back on and sat down her face came into the light and his eyes widened. Jack had just seen his baby sister's naked body. And he felt turned on still by the sight, shocked and felt a little odd when seeing it was Jamie. He just looked at the TV and watched the movie the rest of the night. Later he drove himself home. Jamie got home a little bit after him; he knew his parents would be pissed if they knew their daughter was drunk.
So he made sure she quietly went to her room. Then he went of to his room and sat at his computer, rethinking his entire night. Then bringing his sisters body back into his head, after recounting the night. Without notice he was jacking off. He stopped went on the net and found some porn suitable. He felt bad masturbating to his sister. But he stops feeling bad about it in the next weeks and actually plots a way to use it. He is no longer ashamed but horny constantly when his sister is around.
She still didn't know that her new friends were his friends or that he was at the party. She doesn't even remember being there.
Things calmed down for a while. Jack still got a hard-on when Jamie was in the room though. One Friday afternoon they had off school. Jack went into the kitchen for food. Jamie was already there in short shorts and a wife beater and bra. When Jack walked in, in his wife beater and shorts and saw her he stopped and began drooling for a minute. She was cooking and right before she turned to look at him he wiped the drool and closed his mouth. Then began approaching the fridge. He then opened it and to look for food and adjusted his full-mast boner to hide it as much as possible. Jamie walked from the sink to get something from the fridge pulled the door from his hand and kneeled to get something from the fridge her way up she ran into his boner. It pressed against her side and she felt the full length of it. Grossed out that her brother had one and that she had touched it and a little embarrassed she hurried across to the sink and oven corner to continue cooking. Acting as it hadn't just happened. Jack quickly grabbed some thing from the fridge. His mind was racing, and then he remembered something and darted to his room. When he got there he grabbed the pictures of Jamie and photocopied them. Stuck the real ones in his drawer and put the others in his pocket.
Then he walked back the kitchen his sister had finished whatever she was making and went into the living room where his dad mom and sister were watching TV. After the show was over Jack got up to throw away the plate of the food he just ate. Before he left the room his parents said "Jack were going to your aunts, we will be gone a couple hours. Bye". Then he went into the kitchen and thought "yes there’s my chance." So he walked back into the living room where his sister was flicking through the channels. He walked over to her and pulled the copy pictures out of his pocket, dropping them on her lap one by one. Her eyes grew wide as she looked and the pictures of her naked with her boyfriend sitting next to where she stood and more people from the party. Jack knew she didn't remember doing that. His cock began to grow in his pants as he watched her looking at them. "Where the hell did you get these!!!?” "What don't you remember?" knowing she didn't. She stood up and grabbed him by the throat and said "Where?! Or Ill tell mom and dad you took pictures of me in the shower". Jacks member grew more as he imagined that. "Hey I'm not the one going to parties and getting drunk then prancing around naked", Her jaw dropped as if she had just learned her dog died. "W-what?" she sat down and looked up at him.
"How do you know I did that and who gave you these". “I was there and I don't think mom and dad would be very happy to know that their daughter is getting drunk and prancing around naked at parties". She had a look of fear in her eyes. "Give me the pictures! and don't tell mom and dad or you wont be able to have children!" Jack smiled "why would I want to do that, I took them. . . . . . I didn't know it was you at the time but as you can see, the camera did" there was a pause and she gave him an odd and angry look "it would be incredibly stupid to give away bait". Her eyes were as wide as when she saw the pictures "Bait? What are you talking about; you’re my brother why would you keep something like that?" "Well if you didn't hang out with drug addicts you wouldn't be in this situation, now you owe me something before I give you these" she grabbed them out of this hand and ripped them up " I don't think I owe you anything, go ahead tell them, they wouldn't believe you without evidence" Jack smiled " Don't be stupid I have more, I figured something like this might happen" she went into a frown pout and her eyes went teary and fearful " Now what are you prepared to do for me so you can have your pictures?" She looked straight ahead of her; she could see the outline of his penis was full-mast as he smiled. She then remembered feeling the length and width of it when she ran into him earlier. She was a virgin, but she was beginning to get horny, and felt risky saying "Ill do anything, just give me those pictures" His smiled turn into a surprised happy look.
He pulled his basketball shorts to the floor revealing his almost 8-inch cock. He pointed and nodded in one motion at it but she already knew what he wanted. "What the hell are you doing you pervert?!!!" "You said anything and I will give you the pictures for nothing less”. With a defeated look she kneeled in front of him getting ready to take him into her mouth. She was secretly raising her hand to squeeze his balls until he gave her the pictures but was interrupted "you'd better not or every in school will have seen you naked by lunch on Monday". She gave a defeated look her mouth hung open with sadness that he caught her before she did it, and then she thought about it, she knew he wouldn't give up the pictures until he wanted and she couldn't get them without doing something for him. She opened her mouth to talk but before she could he grabbed the back of her head and planted all of his 8-inches down her throat and gave a deep moan. She tried to struggle but it didn't work, she knew he had her, and there was nothing she could do but do what he said. She began to gag but it subsided. Then she turned him around and sat him down on the couch. She began sucking his cock, bobbing up and down with his hand on the back of her head but not forcing anything. She continued to bob and twist her tongue around and round playing with his head then rubbing it fast with her tongue, jacks head fell back and he said "oh yeah! Just like that!"
She began to go faster, he knew his orgasm was soon so he got up and sat her down on the floor against the couch and began banging her mouth. Until he started cumming, he came all over her face and moaned progressively as he did so. Then he put his shorts back on just as his parents car pulled in the driveway. He said "you'd better get cleaned up and take care of those pictures there" before he left the room. She threw the pieces of pictures in the trash then went to his room “where are the others at?", jack laughed " that wasn't all your going to do that’s just one thing, by the way you give really good blow jobs sis” then he winked and shooed her out. She heard the front door open and ran into the bathroom closing the door lightly so her parents wouldn't think something was wrong. Jack thought to himself, wow I have my own personal sex slave for a sister, I think Ill let her have them after I get to screw her in the twice . Jack thought it over more over the next week. He knew exactly when he wanted to do it. His parents were going out town on Friday afternoon so when they got home they would be alone. Jack got inside first and his sister after him “you better not do this stuff with your boyfriend; he’s my friend he'd tell me he doesn't know were related".
The funny thing was they had different last names Jack with his moms name and Jamie with her fathers because the parents were married after they had jack. "Don't worry I plan on waiting for marriage, pervert" "Sorry but I’m afraid your not waiting for marriage anymore your waiting for tomorrow" "What no way! A blow job is one thing, but I’m not having sex with you" "Alright but just know that I’m going to make some extra copies and sell some on eBay and post some online, others Ill give around the school tomorrow". Jamie stormed off to her room and slammed the door. Jack knew she wouldn't say no, so he didn't bother making more copies. Jack was getting ready for bed when his parents said they were going to dinner and a movie and they wouldn’t be back till late. Jack was almost to his doorknob when he thought of something. He heard the front door close and was sure he was alone. He walked down the hall to his sister’s room and opened the door a little. She always went to bed an hour earlier than him, and it was no different tonight she was fast asleep. He snuck into the room and closed the door. He then walked silently to her bed where she was covered up and spread eagle with nothing but a thong and a bra under the covers. He lifted the covers a little and looked at her sound asleep, and then he went under them, and found his way by the moon shining on the blanket from the window.
He found his destination with his face right next to her pussy. He slid the string to the side and flicked his tongue across her clit she let out a deep moan, still half asleep, thinking it was a dream he stuck his tongue all the way in and wiggled it, then he began to eat her pussy like starved man at a delicious cake, she was awake now, he slid his hands under her thighs and around to hold her hips, digging deeper in making her moan louder and louder. He tongue screwed her next and this sent her over the edge, he backed away so he didn’t get any on him but licked the remnants from her pussy lips before driving her almost to the edge again before stopping getting up and going back to his room to go to sleep leaving her horny. She was so tired from the first orgasm she fell asleep horny. The next morning on the way to the shower wearing nothing but a towel, his parents dead asleep, his sister pushed his back hard against a wall as she rubbed the outline of his cock. She said "don’t spread those photos, I’m keeping to my word, Ill do anything but you better give me those photos soon, if I don’t have them by Saturday Ill tell everyone what you did to me". Jack just smiled and walked away, planning to give them to her anyway after he fucked her brains out.
His school day went quite well nothing amiss at all, she sat with her boyfriend at lunch which didn’t bother him he sat on the other side of him and asked for an introduction. They both acted like strangers. When Jamie got home that day she was there alone until an hour after she got there. Jack came home and walked up to her in the kitchen and gave her a long French kiss, both hands holding her butt all the while. She was in her normal house wear, short shorts panties, (except for no bra) and wife beater. Before going to his room to get comfortable he grabbed a handful of each boob massaged them, making Jamie contort her face in pleasure and kissed them. Spanking her he went off to his room horny as ever. He returned ten minutes later with the pictures and a couple condoms. He thought this is it I’m finally going to get inside my sister. He put the pictures on top of the fridge where she couldn’t reach. Then he pulled his shorts off as she was washing dishes. He tapped her on the shoulder she turned around and went straight for his cock with her wet hands and jacked him off, he was shocked at how much she was doing almost like she wanted to. Catching all his cum about 15 minutes later in her mouth and swallowing, she finished the dishes while he recovered.
He didn’t expect that, but then she took her short shorts and her panties off and hopped up on the counter with her legs spread. "So I guess you remember last night huh?" she nodded with a smile and pulled his head to her crotch. So he began to eat her out she soon wrapped her legs around his head in ecstasy. Minutes later she was moaning wildly and girl cum was filling his mouth, he swallowed it in gulps as it came. Then he stood up and wiped his mouth. Jamie leaned against the cupboard behind her panting and recovering from that powerful orgasm. "We both had an orgasm but two more things that we need to do before your free". Panting she said "what?", "I’m going to deflower you and one thing after that but first" he threw her a condom,” I need you to put that on for me but first you need to help me wake him up" She was too tired and in too much pleasure and getting horny as well to resist. She removed her shirt and wife beater. Revealing her boobs to him and playing with them. His cocked began hardening as he walked over and took one nipple into his mouth going back and forth until she neared orgasm then stopped. “I’m fully hard now" he said. She put the condom on his dick with her mouth, her friends showed her before on a cucumber.
Then he walked up to her and picked her up by the ass and lowered her onto his member. She began to shake with pleasure as he kept lowering her until he reached the hymen. He then walked with her on him to the couch and laid her down under him, then he grabbed her shoulders and trusted forward with all his might. Her legs wrapped around him. He broke the hymen with the first thrust, she was bleeding and in allot of pain, hitting him trying to get him off in any way possible. But he didn’t budge. He waited a minute then began a repetition, after the third thrust she began matching his as pleasure replaced pain and they began going faster. "Fuck me Jack, fuck me brother, Fuck your baby sister, in her virgin pussy, oooh" he replied in pleasure” oh you want more? I’m going to fuck your brains out" he began thrusting hard and faster every thrust. She was matching him as they both elevated. "Oh baby, sister you feel so gooood oooo" they both were letting out load moans, nearing their orgasms. Jack plunged in hard and deep one final time pouring cum into her; this sent her over her third orgasm during him banging her. Then jack rolled over and they recovered with her lying on him.
When they both were able to get up Jack grabbed Jamie’s hand and said, get in the position like your doing the dishes again. She did without thinking about what he might do. His condoned cock was alright lubed by her pussy juice but for extra lubrication her slide in and out of her pussy one more time. Then he placed his cock head on her anus grabbed her shoulders and slowing thrust in while playing with her right boob. He slid all the way in and stood up straight which lifted her feet off the ground and she let out a deep moan of both pain and pleasure. Then he began pumping in and out of her butt loosening it a little as he went, he also began fingering her pussy with his free hand once he was ready he kept her on his cock but put her doggie style on the couch and continued, he moved in and out faster, and harder her pussy juice dripping down lubricating it. She began moaning high pitched and deep, they were both nearing orgasms, right before his hit he flipped over laid on the couch and turned her on his cock so her boobs were facing him, then she did the up and down motion he matched it, they both let out deep moans and orgasmed, once the orgasms subsided he fell asleep and she fell asleep on top of him.
