He had little time for anything but working on his 1970 Chevy Chevelle SS. He had an occasional girlfriend, but they soon got tired of competing with that damnned car, and he didn't much care one way or the other. He'd saved his money from summer jobs, and had finally been able to buy a LS7 454 Cubic Inch motor. It was one of the best looking and running cars around in his town, but it also had a small problem. Too much compression and performance for the low grade fuel available. Trying various octane boosters and other modifications, he'd heard about using a Nitrous Oxide Injection System. Checking into the costs,he decided that this would be his best choice. It would also be a choice that would change his interests drastically on many subjects. Late Saturday evening found Steve working alone on installing his NOS(Nitrous Oxide System) onto his Chevy. He was just finishing the installation of the brackets used to hold the NOS Cylinder in the trunk of the car, when his 13 year old sister Gina came in with her girlfriend Carla. "Whatcha doin Stevie?" Gina asked in her usual screechy tone.Hitting his head on the trunk lid, Steve was surprised, and now pissed. "What the fuck Gina! Can't ya see I'm busy here?" he nearly screamed. "I'm sorry, I didn't mean to scare ya, but I was wondering if you could take Carla home when you're done fixin this thing" she asked in her best"suck up" voice. Now Carla was not your average looking 13 year old. She had long brown hair, big brown eyes, and the cutest little ass and tits he'd ever seen. She was also a prick teaser way beyond her years. She knew she had a good looks and a great body, and she could flirt with the best of them. Being a warm summer night, she was dressed in a tube top and a pair of cut-off shorts. Steve peered over the trunk lid and just looked at her cute little tits and legs. "Ahhhhhh, shit, I don't know when I'm gonna be done with this thing, it'll probably take me at least another hour before I'm ready to take it out for a test run, and besides that, why doesn't she just stay overnight like she usually does?" he said as he went back to work on the car, and shook off the thoughts in his mind. Gina, who also was no slouch when it came to looks, having short blond hair, blue eyes, and an angelic face, replied with a whine, "Awwww please Stevie. I have to go to Debbie'shouse with Mom in a few minutes cause Deb's Mom and us are gonna go shopping early in the morning, and I'm gonna stay overnight there. Besides, we told her Mom that you said you'd take her home already." "You WHAT?!!? Steve yelled as he came out from under the trunk. "What the fuck did you tell her that for?I ain't got time to be a goddamnned taxi ya know." Carla hadn't said a word yet the whole time they were in the garage, but now she grabbed Gina by the arm and said disgustedly "Aw forget it Gina, he's bein a real pain" and began to tug Gina away. "Wait", Gina said and pulled away, "I never told Mom about you and your buddies drinkin beer in here last week Stevie, so you OWE me a favor. This is my favor, and then we're even" she said with smug assuredness. Steve knew she'd tell on him, so he had no choice but to agree. "Allright you little shit, but this is it. We're even after this. Right?" he said with angry resignation. "Yep, even Steven." she said with a giggle, and trotted off to go with her Mom to her other girlfriends house. A minute or two later,he heard them get into his Mom's car and drive off. Looking over the trunk, he fairly snarled at Carla "Sit down over there, and don't touch anything. I'll get you home just as soon as I finish this." as he pointed to a chair. Next to the chair was the bright blue NOS cylinder. Carla sat down with a bored "hmmph" sound and just stared outside. Steve continued working on the hoses and valves for the NOS system, and then he heard music."Who told you you could turn on the radio?" he asked. "I'm bored" she replied and walked back over to the chair and sat down. "Tough shit. Just sit thereand I'll be done in a few minutes" he replied and went back to work. Carla stuck her tongue out at him as his head disappeared under the lid, and her fingers found the valve on the NOS Cylinder. Turning it slightly, she heard a faint whooshing sound, but no smell. With the music on, Steve did not hear any of this. Crinkling her nose, Carla opened the valve some more. She bent over to smell the escaping gas, but there wasn't any discernable odor. She sniffed it for a few seconds, and sat back upright. All of a sudden, she started to giggle. She hadn't turned the valve off, and the gas kept wafting upwards towards her. Her giggling turned into loud laughing, and Steve heardit. He walked over towards her and heard the gas coming out of the bottle. "What the fuck are you doin!" he screamed at her and turned the valve off. Carla was laughing and her head began to weave and bob. Steve grabbed herby the shoulders and picked her up from the chair. She immediately went limpin his hands and he almost dropped her on the floor. He dragged her deadweight body over to a mat he used to lay on when he worked under the car.He was scared what was wrong with her. He lowered her down to the mat, andas he did, her tube top caught on his arms as she slid through. There she layon the mat, with her cute little tits just staring up at him. "CHRIST" hesaid to himself and pulled the tube top from around her neck and tried to placeit back on her young firm tits. He looked at her face, and saw she was totally unconscious. As he was trying to put the top back on, his fingers couldn't help but brush against her firm mounds, and his dick unconsciously got hard. Then it hit him. "The Nitrous!" he thought to himself, "Shit, that's LaughingGas, just like what they use at the Hospitals. No wonder she's out cold" Anevil thought crossed his mind. "I wonder just how "out" she is?" Carefullywatching her face, his fear turned to lecherous thoughts. Putting his handat her crotch, he pushed slightly down on her pubic mound. No reaction showedon Carla's face. Getting bolder, he pushed a finger under the leg of hershorts and probed near her pussy. He felt the legband of her panties, andwormed his finger past it, and felt her soft hair on his finger. Still noreaction on her face, and he decided to go further. Unsnapping the waiston her cut-offs, he unzipped them, and pulled them down past her thighs. Ashe pulled, he panties came off with the pants, and he had a clear view of hersparse haired pussy. He just couldn't help himself, and he pushed her legsupwards and then spread her legs so he could see her pussy wide open. Helowered his head and put his nose right up to her pretty pink hole, andtook a deep sniff. It had almost a powdery smell. Real clean and sweet. He wet his finger, and put it at the opening. Sliding it up and down,he found the hole and slid his wet finger into her. It felt so warm andtight, that he almost came in his pants right there. He wasn't quitebrave enough to attempt fucking her, at least not yet. He pulled his fingerout and tasted it. It tasted as good as she smelled. He licked it again, andput it up to her tiny little puckered pink asshole. He'd never played withany of his girlfriend's assholes becuse they wouldn't let him, but he alwayswanted to try it once. He pushed the finger slightly against the crinkledhole, and finally it gave way. Up it went into her tiny ass. He begancorkscrewing his finger around as he pushed deeper into her bowels. The sightof his finger against her cute little ass cheeks made him shiver. He justhad to try it. He pulled his finger out of her ass and looked at her face. Still no expressions or changes, so he pulled his pants down and was goingto put some spit on his cockhead, but found that it was covered with lubrication already. Smearing it around the head, he pushed her legs back again, and put the head up to her pussy. Rubbing it up and down, he felt theopening and pushed his hips forward slightly. He watched as the head slowlydisappeared into Carla's young, tight pussy. He pushed a little farther andfelt her hymen blocking his way from entering her any further. Her pussy wasso tight and felt so good, and the sight of his dick stuck into this almosthairless pussy alomost made him lose control, but he didn't want to try topush through her cherry. He reluctantly pulled out of her pussy, and was goingto pull his pants back on, then decided to try her asshole. "No cherry thereto break" he thought, and since his dick was so slick now, it might slide rightin. He put some saliva on her asshole anyway, just for the hell of it, and puthis swollen cockhead up to her tiny anus. The head of his dick was much biggerthan her little hole, but he'd heard of others doing this, so he decided hewould try it. Pushing harder and harder against the tight hole, it finally gaveway and allowed his prick to sink deep into her rectum. The tightness ofher ass was unbelievable, and almost before it started, it was over. Stevehad to pull out almost immediately and came all over his own legs. He grabbeda rag and wiped himself off, then wiped off Carla's entire crotch area. He pulled her panties and cut-off's back on, and sat watching her. Finally,after about 5 minutes, she slowly regained consciousness. It was a total ofabout 30 minutes that she had been out, and she seemed no worse for the wear. "Ohhhhh, what happened?" she said groggily as she sat upright and looked around. Thinking quickly, Steve answered "You fell off the goddamnned chair you jerk! I thought ya killed yourself." "I what? I don't remember doing that. Did I hit my head?" she asked in a confused tone. "Beats the hell outta me. I saw ya laying there and moved ya over to the mat. I was gonna call your Mom orsomeone if you didn't straighten out real soon." Steve said with a convincingtone of aggravation and and concern. "Geeez, don't say nothin to anyone aboutit. They'll think I'm on drugs or somethin. Just take me home ok?" Carla said as she got up carefully. Once standing, she rubbed her ass, "I think I musta fell on my butt real hard. It's kinda sore" she said with a mild grimace. "I don't know what the hell ya did, but let's get your ass home and outta myway" Steve said shaking his head, and feeling a new sense of glee. He thoughtto himself as he started the car, "Man, this is the best investment I ever madein my life. I can't wait to try this out on a few of those stuck-up bitchesat school." He drove off with Carla and dropped her off at home, watching as she walked up the stairs of her house with a gingerness in her step. "We'llhafta do this again" he smiled to himself and drove off with many plans inhis head about who was next to discover his new found way with women. When Steve returned home after dropping Carla off, he went back into the garageand cracked the valve on the NOS cylinder open slightly. "No odor" he thoughtto himself. After a few brief whiffs, he began to giggle and laugh. Quickly,while he still had the presence of mind, he closed the valve. "Boy, that stuffisn't called Laughing Gas for nothin" he said to himself. He began to thinkabout how he could use this to get some of the real "stuck-up" bitches at school right where he wanted them. He'd need some help, a partner in crimeso to speak. His best friend Del Hawkins would be perfect! Del was a bigguy, weighing almost 225 pounds, standing almost 6'3" tall. Even though hewasn't a bad looking guy, he didn't have much luck with the girls. "Yeah,Del will get a bang outta this. Literally" Steve chuckled to himself. Butbefore he did anything else, he had to make sure that this stuff workedlike it did with Carla. He had to be sure that any girl he tried it on would react the same way. He decided he would try it on his sister Gina. "Little bitch is always spying on me and gettin me into some troubleanyway. Maybe I can turn the tables on her now." he thought with an evilgrin. He finished up installing the NOS system in his car and took it outfor a test drive. It worked flawlessly. "Two uses for one device. What agreat deal!" he smiled as he pulled the car into his driveway, and then went in to bed. All the next week Steve tried to find the right opportunity to try the NOSon his sister Gina. Carla came over during the week, and seemed fine. Shewas walking around ok, and even talked with him, and thanked him for takingher home and not saying anything about her falling down. Steve was feelinggreat with this new power he'd found, and the perfect chance came on Fridaynight when his sister's friend Debbie was going to stay overnight at theirhouse. Steve's Mom stopped him outside as she was going out shopping "Steve,Gina and Debbie are going to have a little slumber party, and your Dad and Iare going out to dinner and a show tonight. Could you please make sure youget home early, like about 10 PM so we don't have to worry about them?" sheasked. "Yeah, ok Mom. I didn't have much goin on tonight anyway, so I'll watchthe little darlins." Steve replied offhandedly so as not to seem too eager."Thanks dear" she said, gave him a kiss, and went on her way. All evening Steve waited anxiously for the right time to try his new device.He'd attached a valve and a hose to the NOS tank and thought that he couldsimply push the hose under Gina's bedroom door, then wait for the stuff to work. As it happened, things could not have worked out better. Debbie hadsmuggled some beers in for them to drink, and they were holed up in Gina'sroom guzzling them down. Every so often one of them would sneak out to checkon what Steve was doing, then dart back into the bedroom. Steve pretendednot to notice, and went on watching TV, giving all indications that he wastoo preoccupied with whatever was on to give a shit what they were doing. A few minutes later, Gina came out of the room and announced that they weregoing to bed. "Who cares." Steve replied and gazed back at the TV. He waiteda few minutes, and then cautiously crept up to Gina's bedroom door. He couldhear them popping the beer can tabs, and giggling away. "This is better thanI could have ever wished for," he thought to himself "not only do I get totry this out, but I'll most likely be able to get some blackmail pics too!"He crept out to get his NOS tank, and slid the hose under the door. Withthe giggling and noise they were making, they never heard the silent hissingof the gas. While the gas was flooding the room, Steve thought to get hisracing stopwatch so that he could get an accurate time of how long they would be out. When he returned to the door, he could hear them laughing hard.He turned off the gas, and returned the cylinder to the garage. Cautiously, he cracked open the bedroom door and saw them both laying on the bed. Takinga breath of fresh air, he went into the room and opened her window. He thenstarted the stopwatch, and went over to the girls. Debbie was the athletic sort of girl who loved gymnastics, running, andvolleyball. He'd always thought that she must be part Oriental because ofher jet black hair, and slightly oval eyes. Both girls were wearing simplePJ tops and shorts. "First things first" he thought, and yelled fairlyloud "What the hell are you guys doing?" If they were the slightest awake,they'd have jumped, but, they lay there silent. He bent over and liftedthe tops of Debbie's PJ's. She had small tits, but they were still nice. The nipples were a very dark rose color, and large. He grabbed one nippleand tweaked it a bit. No reaction at all. He then decided to get his"insurance policy" first, before he had his own fun. He went to his roomand got the Polaroid camera his parents gave him for his birthday last year.Once back in the room, he checked the stopwatch. 5 minutes had elapsed sincehe started it. He pulled Debbie's shorts off, and pulled her top back downto cover her tits. He then spread her legs slightly, and put one of them offthe edge of the bed. He licked his lips at the sight of her snatch. The hairwas straight as an arrow, and pitch black, that is what hair there was. Next, he pulled his sister Gina over towards Debbie's crotch and pulled hertop off. "Not a bad set of tits Sis" he grinned and placed her head inchesaway from Debbie's pussy. He grabbed a few beer cans and positioned them sothat they would show up in the pictures. FLASH! Whrrrrr. FLASH! Whrrrr. Againand again he snapped shots from every angle. He decided it would be better totake all of their clothes off, and then take some more. After doing so, helooked at the blond trimmed snatch on Gina. He hesitated for a moment, butthen he lowered his face to her pussy. He pulled her legs apart and pushed histongue up into his little sister's pussy. It smelled and tasted different thanCarla's did, but it was still great. He pulled back a bit and looked at herexposed crotch. Her pussy lips were more red than pink, and her asshole hadalmost no color to it at all. He wet a finger and pushed her legs back againsther chest, then he slipped his finger into her asshole. It slid in quite easilyhe thought. "Nice bod Sis" he grinned, and pulled his finger out. He then laidher back down, and went over to Debbie. When Steve pulled Debbie's legs up, he could see the dark color of her snatchmatched that of her nipples. Pulling her to the edge of the bed, he knelt downand let her legs drape over his shoulders. He licked her entire pussy and assuntil it was very wet, and he was very hard. He tried to push a finger into herass, but found it so tight, that he was afraid to push any harder. He took herlegs from his shoulders and spread them wide. He pulled out his dick, and rubbed it against her wet pussy. Finding the hole, he pushed slowly in. It went deeper and deeper into her vise-like snatch, and finally he felt hisballs rest against her little asscheeks. He flexed his cock inside of her, andthen pulled slowly back outwards. He paused a moment with just the head firmlystuck into her, and then let it plow back in. He began to pump in and out of her, each time feeling the tight walls of her pussy caress his cock. Everytime he would hit bottom, he could hear his balls slapping her ass, and it made him want to go faster and deeper. Gripping her asscheeks, he spread them wide and pumped into her savagely. He felt his balls hit her asshole each time,and his belly slapped against hers with a smack. He felt his balls swell, andpulled out of her little pussy, spraying cum all over her belly. In a fewmoments, after he caught his breath, he went to get a wet towel to wipe herclean. On his way back it occurred to him that she didn't have a cherry. "I wonder who she's been fuckin?" he thought as he wiped his cum from herbelly and chest, "I wonder if Sis is doin anybody". He pulled Debbie's topdown again, and layed her exactly like she was in the pictures. He went overto Gina, and spread her legs. He wet his finger and pushed it into her blondsnatch. He probed around, but didn't feel anything blocking his way. "Little Bitch is screwing around too! Probably that dork Larry." He put Gina in the position she was in when he took the pictures, and checked the stopwatch. It was just over 25 minutes. Steve got an idea how to even make this better. He picked his Sister up, and carried her to the bathroom. He pulled her shortsoff and propped her up in the shower, then turned the water on. As soon as it hit her body, Gina awoke with a screech. "What the fuck! What, where?" she hollered. She looked to find Steve standing right outside the shower. "You stupid little bitches! Gettin all fucked up on booze huh?" he said menacingly. Gina realized that she was naked and tried to cover herself. "Don't bother" Steve said "You two were havin a real good time and making all sorts of noise when I came in. Then you were fallin all over the place, so I put you in here." "Wha what are you talkin about?" Gina said as she huddled in the corner of the shower. "Get dried off and I'll show you" Steve said and walked out of the bathroom. He quickly gathered his stuff from her room, and found that Debbie was just starting to stir. He put the camera and watch in his room and met Gina in the hallway with the pictures. "See these?" He said showing her the shots. "Om my God!" Gina cried and lurched to grab them from him. "No way you little bitch. You two are gonna do whatver I say, whenever I say it, or I am gonna leave these somewhere that Mom and Dad can find them. Then your little asses will be in deep shit." Steve said as he held her at bay. "Why are you doin this Stevie?" she whined. "I'm tired of you always usin some shit to get me to do what you want, so now it's my turn." Steve said with an evil grin "Now get back in your room and clean that shitpile up. You better tell Debbie the facts too, and after your done gettin all that crap cleaned up, I wanna see you both in MY room." Gina started sobbing and walked away. Steve went to his room and hid the pictures. After awhile, heheard a soft knock at his door. "Come in" he said and sat back on his bed. Gina and Debbie walked in with their heads down. "What do you want?" Gina asked in a beaten tone of voice. "Well lots of things, but we'll discuss that later. First though, do you both understand and agree that you will do whatever I tell you to do?" Debbie and Gina looked at each other and nodded. "I didn'thear your answer. What did you say?" Steve said loudly. A soft "Yes" came fromeach girl and he sat back smiling. "Good. Since I missed the most of your little show, I've decided that I wanna see what you two look like. Take offyour PJ's and lie on the bed." Hesitantly, the two girls began to take offtheir pajamas. Steve watched as they did what he told them, and sat back witha grin. After they were totally naked, he stood up in front of them. "OK, nowget dressed again. Then go back to your room. That's all for tonight, but we'lltalk again soon." The girls grabbed their PJs and left his room quickly. Stevesat back down and thought of different ways he could use these two to get moregirls for his desires. He decided to let Del in on his secret tomorrow, and fell asleep with a very satisfied grin. ------------------------------------------------------------------------- To find out more about the anon service, send mail to help@anon.penet.fi.
