Alastair 16 and Malcolm 15 were your typical siblings. They were frenemies at home but stuck up for each other when outside. Altogether they were unremarkable, so what the heck happened to make them go astray?



Opportunity and happenstance was the formula to start things down a path that neither could have anticipated. Not that they ended up complaining.



As Alastair was considered "old enough" to be responsible their parents left her in change while they took a get away long weekend for their wedding anniversary.



Alastair decided she was not going to have any friends over or let her brother have any over either. Both knew that if they messed up they would be severally punished especially as this was their first opportunity to prove they did not need adult supervision.



After their parents drove off they decided to watch a movie. Alastair went into their Dad's DVD collection grabbed an "R" rated movie. This of course would not have been allowed to watch if their parents were home.



Malcolm produced a small baggy of pot and rolled up a couple for Alastair and himself. This was no surprise to her as she already knew he smoked-up. She indulged on occasion and it was one of those occasions. Considering they would not have any friends over she felt that this was a fairly safe transgression.



They both were toking when the movie started. There were some semi nudity and fairly hot scenes but nothing too crazy. Alastair was getting a bit worked up and wondered how the movie was effecting her brother. She look over at Malcolm and saw a real nice lump in her brother's pants. She felt herself getting a bit hotter but figured it was just the movie and the pot.



Near the end of the movie the electricity went out leaving the house in utter darkness. Malcolm went to a window opened the drapes and reported that it must be a blackout as the whole street was dark.



They scrambled around and found candles and a flash light. After they had lit enough candles to at least see. Malcolm suggested that they play truth or dare. They played a few rounds of the game but started to get bored as the truths and dares were too tame.



Malcolm rolled another joint and they smoked some more. Alastair still a little aroused dared Malcolm to show her the bulge she saw earlier. Without hesitating he pulled off his pants and stood in profile so sis could see what she asked for.



It was lucky that they were only in candle light or he would have seen Alastair go all red. She could barely believe how big the bulge was. She had not done too much with boys yet. Alastair had been felt up through her cloths and rubbed herself against a boys hardon but not much else.



On his turn Malcolm's asked her a truth "Tell me with details of your first orgasm". Alastair immediately sucked in her breath and knew she had just lost a chance to tell a lie. Malcolm laughed "This is going to be good".



Alastair said "Well, I'll tell you but you can never tell another sole or I will make your life a living hell". Malcolm replied "Fair enough".



Alastair started her story, "One morning when I was twelve Mom had not done the wash all week. I was down to only a few clean underwear. I picked a pair that were too small. They tended to rub me so that I became aroused. I did not really understand what was happening but as the day went on I started to fidget more and more.



It was like needing to pee but not being able to get to the washroom. I was in the family room with Dad and could not sit still. He saw my state and asked if anything was wrong. I told him I was OK but kept fidgeting.



I started to play with Mom's center piece on the coffee table and Dad told me to stop. In my state of agitation I could not stop. The inevitable happened and I broke off one of the center piece's small figurines.



Dad shook his head and said I was going to get punished. He took me to my room and placed me over his lap. When he lifted my skirt to start my spanking my underwear was stuck deep in my butt crack and pussy slit.



As Dad started the spanking a flood of sensations washed over me. The excitement of being exposed to a man, the pain of Dad's hand slapping my bare tushy, the rubbing of my clit over his knee and my tight underwear buried in my slit had my body climbing towards an orgasm.



With each smack of his hand I moaned and cried out 'Daddy'. After a dozen whacks I had a very powerful orgasm. My body shook and I cried out 'Oh GOD'! Dad was scared thinking he had really hurt me so he held me tight as my body spasms slowly dissipated.



I know he had no idea that I had an orgasm as he sent Mom up to see me. She asked if Daddy had hurt me. I told him no I had been bad and needed to get punished. That was the last time Dad ever spanked me".



Malcolm said "Wow, you came for your Daddy, wild sis". Alastair defended herself with "I was too young to know what was happening. I came but not really for my Daddy as you put it. Well it is my turn so little bro what is the wildest sexual thing you have every done, if any"?



Malcolm snickered "Well I ate out sisters"! Alastair was in shock as she had no idea her little brother had done more to a girl than she had done with a boy. She even had a short bust of envy.



Malcolm continued "I have never told anyone this story as I try not to kiss and tell. I was with Patricia Jensen. We were in her room necking and I said I would go down on her. She was real worked up and let me pull off her panties. I used my tongue and fingers while she gave directions. Soon she came very hard. What neither of us knew was her little sister was watching.



To make a long story short her sister threatened that she would tell unless I did the same to her. I had little choice so I went down on her sister. One thing lead to another and they sucked my cock. We ended up spending the afternoon having oral sex. We started doing this regularly. It almost broke my heart when those girls moved away".



If Alastair was in shock before she was now looking at a brother she never knew. It was Malcolm's turn and he asked "Alastair do you use a vibrator to get off"? She replied "Dare" which prompted him to say "I want you to reenact the first time you had an orgasm. I'll be Dad".



Alastair was stuck, Malcolm would win if she refused. So much was swirly around in her head. She was high, horny and jealous of his experiences. She was thinking that this would not be considered incest as he would not be only spanking her ass.



What she had not told Malcolm was that occasionally she would masturbate to the memory of that first orgasm. She would come but without the spanking it was never as powerful as the first time. More than once she fantasized that she was across her Daddy's knee getting a bare ass spanking. So this request from Malcolm was really a big turn on.



She told Malcolm she would take his dare but he could not smack her ass too hard and he must stop as soon as she came or was told to stop. Malcolm agreed saying he had no desire to hurting her.



Alastair took a candle upstairs to get on her "spanking outfit". She fished around in her dresser finding appropriate too small underwear. Changed into a skirt and on the spur of the moment removed her bra and put on a tight t-shirt.



When she got back down stairs Malcolm had placed a dinning room chair in the middle of the family room. Alastair reminded him that he was sworn to secrecy and he replied that they both had enough blackmail material on each other to ensure no loose lips.



Alastair said "Well you must remember that when this happened the underwear had been rubbing me for half a day so I was already worked up. Maybe you can help me by rubbing up and down my inner thighs while I massage myself a little".



Like Malcolm was going to argue. He sat on the chair and Alastair stood in front of him. She started rubbing her clit by pulling her underwear into her slit. Malcolm lightly placed his hands on her inner thighs raising and lowering them slowly.



Alastair really liked his gentle touch. She knew for sure that little bro had really down the things he told her. Any other guy that touched her had been much rougher and too urgent.



It did not take too long before she was getting wet and ready. On the spur of the moment she decided that the skirt was just being a hindrance. After all he was going to see her bare ass checks in a minute or two.



Alastair stopped rubbing her pussy and undid her skirt letting it fall. Malcolm moved his hands and they settled around her ankles. His face was less than a foot from her pussy and he got a strong whiff of her womanly scent.



His hands went back to stoking her inner thighs. Malcolm was trying as hard as he could not to wreck this erotic moment by over stepping the limits his sister had placed on him. What he could not stop was the head of his hardon from escaping the waistband of his underwear.



Alastair had returned to pulling her panties up and down simulating the special rubbing of that first time experience. She had her eyes closed. She felt Malcolm's panting warm breath on her pussy and opened her eyes. When she saw Malcolm's face she also saw the head of his cock and automatically licked her lips.



She was going into sensory overload. With one word "NOW", Malcolm's head moved back and she placed herself across his lap making sure her pussy mound was in contact with his knee.



She almost came when her brother placed his hand across her bare ass checks. Malcolm gave her cheeks a little squeeze and said "Alastair are you ready to be punished"? Alastair was so hot that she barely whispered "I've been naughty Daddy, I need a spanking".



He raised his hand up and she clenched her ass ready for the first whack. When it hit her clit was driven into his knee and the panties tightened up just like those years ago when Daddy made her come. Soon the room crackled with the echos of her brother's spanking.



To Alastair this repeat was even better than the first time as it was accompanied by the illicit knowledge of having her little brother see her exposed and vulnerable. By the time he reached twelve whacks on each cheek her ass was stinging and must have been very red. Her shoulder bumped into his hardon.



Her aroused state left no time to think and she placed her hand under his underwear's waistband and grabbed his cock. It was bigger than any she had felt before. With each of Malcolm's smacks she stroked his cock.



Malcolm could not stop himself and gave a lower smack making a small amount of contact with her pantied pussy. This was more than Alastair could take and she came harder than at anytime in her life screaming out "IIIIIIIIIII'MMMMMMMMMMM CCCCCCCOOOOOOOOMMMMMMMIIIIIIINNNNNNNNNGGGGGGGG".



Her body shook and spasmed. If it was not for Malcolm pulling her onto his lap and into his arms she would have fallen to the floor. Malcolm gave her a soft loving kiss which she returned it the best she could in her post climatic state.



When she finally opened her eyes Malcolm was smiling at her and said "Sis that was awesome". She replied "Shut up and kiss me". They sat kissing for a while until Alastair felt she could stand up.



She went to gingerly sit on the couch. She turned to Malcolm and said well since you have made my ass so sore you are going to have to put some lotion on it the kind used to numb sunburn. Alastair directed Malcolm where to get the lotion and also to fetch a couple of towels.



When Malcolm came back he placed one of the towels on the floor. Alastair laid on it and told him to be gentle as her cheeks were real sore. She felt the lotion being poured onto her butt cheeks.



When Malcolm's hands touched her touchy she jumped a bit but he was gentle and she relaxed. Soon his massaging started to arouse her again. She thought to herself that her little brother may have had more experience than her had let on during the game.



Alastair asked Malcolm "How far have you gone with a girl"? He did not say anything for a while and then admitted to having intercourse for well over a year now. All she could do was shake her head. She went on to asked "Do I know the girl". He replied some "Some". Alastair looked over her shoulder and said "SOME"!



He said "Well you already could imagine that the Jensen sisters did not stop at oral sex. With her parents working many weekends and after school taking care of their bakery we had plenty of private time. We learned together, then when Patricia was to move she gave me a going away present. She spread around that I was very good in bed and had the tool to help out any girl in need".



Again Alastair had no idea what her not so little brother had been doing while she was trying to be a good girl. She said "Wait a second you said I knew some of your conquests. I did not know the Jensen girls. Who do I know"? Malcolm reminded her that he does not kiss and tell, something she should respect.



It stuck Alastair like a thunderbolt. She had had a pool party and seen her best friend Gina give Malcolm a quick kiss. At the time she had written that off as Gina was a flirt and a tease. Apparently she did more than tease. Alastair said one word "Gina"? When Malcolm did not reply she said "The slut. Was she good"?



Finally Malcolm said "She's learning". At that his thumbs slid under her panties and massaged her anus. Alastair taken off guard moaned and Malcolm pleaded "Please do not tell her you know. Are you mad"? Alastair replied "OK I wont let on that I know but I feel a little uncomfortable knowing my brother is a stud fucking my girlfriends".



Without thinking she said "In someways I am jealous as I have never even had oral sex before". Malcolm's hands stopped massaging and the silence was deafening. In a calm voice Malcolm asked "Alastair do you want an early birthday present from your brother"?



Alastair mind was careening around. Of course she wanted the experience but with her brother? Well if neither blabbed she would retain her reputation. If she agreed she would be committing incest one of the biggest taboos in society let alone the law.



In the end hornyness won out and she sat up and took his hand leading him to her room. When she got to her bed she asked "How do you want me"? He just leaned forward and kissed her with tongue better than any guy she had dated. Despite all the taboos this felt just plain right.



When the kiss broke Malcolm lifted her shirt over her head and laid her on the bed. He got beside her and they started kissing again. Soon he took her hands and put them under her head while he kissed her neck down to her breasts.



She was moaning even before his tongue flicked over her nipples while one hand ran over her breasts, stomach and pantied pussy. His sister soon realized Malcolm had learned his "how-to excite a women lessons" very well. Alastair's body squirmed and wriggled to his touch.



Both of his hands were on her breasts with his mouth worked down to her stomach. As he got to Alastair's panties Malcolm hooked fingers into her waistband and pulled the panties right off in one quick motion. Her closed eyes popped open looking into Malcolm's face.



He said "Big Sis what do you want your brother to do for you"? The excitement of being so exposed and aroused did not let her think or hesitate and Alastair replied "Make your big sister come. Please Malcolm, make me come".



He spread Alastair's knees pushing them up to either side of her chest. She tingled in anticipation as his mouth descend upon her wanton pussy. Malcolm used his lips to trap her outer labia then pulling back stretching them. Before they retracted he licked them then his tongue started a long slow lick of her clitoral hood. Then he repeated the pattern wetting her entire slit.



Alastair was already moaning but her panting and "aahs" told both of them that he was teasing her like no one had before. Soon her clit became erect and the little nub made its first venture out to be rewarded by Malcolm's tongue's quick flick before he once more gave that long slow lick of it's hood.



She gasped as that flick was like electricity shooting directly into her mind. Alastair "oooohhhh just like that, please more please" but Malcolm continued his slow deliberate manipulations of her body. Her pelvis tried to rise but he had her legs pinned back.



Her pussy was weeping slick girly come which he moved a finger to scooped some up. The finger ran up her slit from love canal to the underside of her clit then rubbed it over the hood. As Malcolm changed from oral to digit stimulation he moved his mouth to her breasts lightly biting and sucking her nipples. Every brief touch of her nub sent more erotic sparks of pleasure throughout her body.



Alastair was building to a climax like none she had every had before. The spanking although spectacular did not have this out of control feeling. She had turned over her climatic rudder to her brother and he was steering her into a storm of sensations.



When her breasts were slick Malcolm was on the move again, back to mouth her pussy. With one hand he slowly inserted a wiggling index finger into her vagina and with the other spread her pussy lips.



His ever active tongue licked from his index finger to the underside of her exposed clit then darted his tongue across it. He repeated this gentle quick action varying the direction of the darting tongue each time.



He would pause and kiss the top of her mound to give her a chance to anticipate his next jolt of erotic sensation. These slight pauses seemed to accentuate his next lick. He was in no hurry to have this end as Malcolm wanted his sister to appreciate his skills.



After many minutes his sister was pleading with him to let her come. His final stoke as it were was to use his tongue to deliver slow, upward strokes against the delicate underside of the clit glans. He retracted the hood, and gently place his tongue beneath the clitoris. Sliding it upward with soft, wet strokes.



Alastair could not take any more and screamed in no uncertain terms she was going to come. Her pelvis rose so fast that his face was pushed off her over sensitive clit. Even when her butt was back on the bed all Malcolm needed to do was kiss the top of her pussy mound and she would experience brief shuddering spasms.



Finally she pushed his face away from her pussy squeezing her legs tightly together. Malcolm was not going to let her body come down that easy as he returned that skilled mouth and hands to her breasts. It took awhile but she started to become lucid again.



When he saw her eyes open Malcolm moved up to Alastair face and they passionately kissed for some time. Malcolm asked "Can you forgive Gena now"? Alastair replied "I can forgive any women for wanting to feel like this. I love you bro. What can I do for you"?



Malcolm smiled and said "Well Sis it is long, hard and needs your tender loving care". She smiled and said "Not so little brother please be my first. Mom gave me the morning after pill so we have no worries. I need you to come in me".



Never in her wildest dreams had she imaged giving her virginity to her younger brother. He had made her feel so good that it just had to be. Malcolm pulled his underwear off. She had felt his cock earlier that evening but seeing it was quit another thing.



He was long with moderate thickness. She would no doubt be stretched but just seeing that beautiful man meat was got her juices flowing again. She was staring so long that when she finally looked up Malcolm had a wide grin asking her "Do you like what you see sis"?



Normally she would have given him a swat but she just reached out to touch it. At the very last second he stopped her then laid on his back. Alastair slithered down to get her face to the level of his groin. She wrapped her hand around his cock.



Alastair gave him a few long slow strokes until she saw a glob of precum bubble out of the end of his cock. Alastair looked into her brother's eyes and giggled "Pay back will be from this bitch". While continuing to stare into his eyes she ever so slowly licked the precum off of his cock getting a stringy from head to lips.



Her tongue twirled around snagging the stringy then around and around wetting the head of his cock. Malcolm groaned saying "Oh yaw sis give me a good licking". While still slowly stroking, her mouth opened wide and she enveloped the first three inches of his phallus. She sucked hard getting all that slick precum into her mouth.



Malcolm groaned "Suck it sis, suck your brother, show me what you got". Alastair pulled off his cock and then moved down to lick and suck his balls. She did not like the hair too much so moved up to the base of the cock and gave him a base to tip lick making sure her tongue was as broad as possible for maximum contact.



She knew he liked that as his cock jumped and pulsed in her hand. Alastair got up over his groin winked at him and then opened wide. She started taking him into her mouth madly licking the underside of his meat stick as she slowly descended down the shaft. Her oral massage was effective stimulation as his pelvis jerked up and thrust the head into her throat.



Much to her surprise she did not have the expected gag reflex. This was something she had never tried before so was unaware of her unique talent. Malcolm's increased panting and groaning indicated that he appreciated her talents.



With control she pulled off of his cock and kissed the tip. Then with a few full breaths started back down the shaft. This time she controlled his hips but still took him right into her throat. When her nose touched his pubs he gasped "Sis you are a wonder. None of my girls have every been able to do that to me".



Alastair has never expected that she would be proud of being a "cock sucker" but she was and determined to give a little sexual delight back to her loving brother. She pulled off again sucking and licking trying to will the cum out of her brother's balls.



Up and off she came again. This time she went down faster to keep him in her throat just a little longer. Her tongue was working him real good. She felt the head of his cock start to swell just as Malcolm yelled that he was coming. She pulled back enough that the ropes of come all spurted into her mouth.



When she felt he was done she kept the suction on and carefully sealed her lips around the shaft and right off the head not loosing a drop. When she looked up he was watching. She opened her mouth showing her bro-reward, rolled it around with her tongue and swallowed. They smiled at each other and she said "Bro I think we like each others taste".



Malcolm said "Alastair straddle my face and I will get you wet then move down and rub your slippery pussy up and down my shaft until I am hard again. When I'm hard use me for your pleasure". She just replied "Sounds like a plan".



Alastair used the head board as leverage to push her pussy into little bro's face. He reached up putting hands onto her still tender tushy and started licking her like before. She was too impatient for his slow tortuous ways and moved her pelvis to force his tongue where she wanted him to be.



The little bastard kept moving his tongue around so her pelvis had to chase the contact. He seemed to know something about her body. Soon she was streaming girly come down and climbing that climax hill again. This time she needed man meat inside of her and moved down to his pelvis.



Malcolm already had a semi so it did not take long for her slick pussy to rub him into another hard erection. She took a hold of his phallus and pointed it straight up then positioned it to her entrance. She rubbed the head up and down her slit mixing her slippery come and his precum so that the whole head was lubricated and ready for her love box.



Alastair was so tight that it took and little work to get the head inside. Malcolm watched her as she slowly worked the shaft deeper and deeper. She grunted when his penis head flexed her hymen. Closing her eyes she seemed to steel herself for the pain to come raised a little and then forced herself down several more inches.



Alastair cried out "Shit that hurts" and tears welled in her eyes then tricked down. She leaned forward laying on Malcolm's chest with over half of his cock still inside her. He wrapped his arms around her giving Alastair a chance to calm herself and adjust to his intrusive member.



After a while her breathing changed and he felt her pussy walls grip and ungrip him. She slowly raised up again and said "Christ Malcolm did you have to be an extra large". The smile on her face said she was ready for the rest of him.



Malcolm's sister slowly pushed herself down his shaft until her butt rested on his thighs. With her head down, face covered by hair he pulsed his cock making her giggle. He said "Just wanted to make sure you had not fallen asleep". She replied "Oh I will sleep alright but not before this big thing makes your sister come a few times".



He wet his thumb and started rubbing the hood of her clit in a circular motion. His stimulation sent waves of sensation mixed with that full feeling. Soon her body moved started a gentle rocking motion stirring up even more pleasure feelings. The pain of loosing her virginity seemed a distant memory as these new sensations dominated Alastair's mind.



Malcolm had one hand circling her clit and the other pinching and teasing her nipples. She felt an urgent need to have her brother's phallus press hard against her stretched pussy walls. Alastair barely heard her own pleasure utterings "Fuck me", "Your cock feels so good", "Fucking me bro, never stop".



The volume of those phrases increased in time as the rocking motion increased finally petering out into a continuous string of panted ohs and aahs. Malcolm knew she was close so he gripped her by the hips and lifted her up then drove her down. She instantly adopted the motion.



Malcolm would thrust up to her downward stroke making a wet sounding slap as they bodies met in the middle. Alastair's hair was flying around like a slow motion replay of where her head had just been. She had reached her peak and her body jumped off into the abyss of orgasmic sensation.



As soon as she collapsed onto his chest Malcolm rolled them over while her pussy walls pulsed to the rhythms of her climatic tremors. He pulled her legs over his shoulders and started a slow long tip to groin stroke, ending with a repeated tap of her cervix with the tip of his cock.



Alastair was not nearly finished her orgasm when she started the pleasure dance to a new one. She thought what a wonder an experienced man can be to a young women even if he was younger than herself.



Soon instinct took over and she was raising her pelvis to meet his reentry. The cervix taps sent arousing pulses throughout her body. She was riding a new climatic wave this one the biggest yet.



Alastair and Malcolm kept this rhythm alive until they mutually felt the need for climax. Malcolm's stroke changed to become faster and shorter picked Alastair met the increase with her own pelvic thrusts. Finally they screamed together just one word "CCCCCUUUUUMMMMMIIIIINNNNGGGG".



He released the remained of his sperm reserves and she came hard onto his cock. Their mixed juices were more than her pussy could hold and the excess dribbled out down her ass crack tickling her anus on its way to her bed sheets.



Malcolm pulled out and spooned his big sister as they fell asleep in mutual bliss.
