The Nitrous Oxide Affair
Steve Makay was your average 18 year old gear-head. 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 of the brackets used to hold the NOS Cylinder in the trunk of the car, when
his 18 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 18 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's
house 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 there
and 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 heard
it. 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 her
by the shoulders and picked her up from the chair. She immediately went limp
in his hands and he almost dropped her on the floor. He dragged her dead
weight 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, and
as he did, her tube top caught on his arms as she slid through. There she lay
on the mat, with her cute little tits just staring up at him. "CHRIST" he
said to himself and pulled the tube top from around her neck and tried to place
it 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 Laughing
Gas, just like what they use at the Hospitals. No wonder she's out cold" An
evil thought crossed his mind. "I wonder just how "out" she is?" Carefully
watching her face, his fear turned to lecherous thoughts. Putting his hand
at her crotch, he pushed slightly down on her pubic mound. No reaction showed
on Carla's face. Getting bolder, he pushed a finger under the leg of her
shorts and probed near her pussy. He felt the legband of her panties, and
wormed his finger past it, and felt her soft hair on his finger. Still no
reaction on her face, and he decided to go further. Unsnapping the waist
on her cut-offs, he unzipped them, and pulled them down past her thighs. As
he pulled, he panties came off with the pants, and he had a clear view of her
sparse haired pussy. He just couldn't help himself, and he pushed her legs
upwards and then spread her legs so he could see her pussy wide open. He
lowered his head and put his nose right up to her pretty pink hole, and
took 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 and
tight, that he almost came in his pants right there. He wasn't quite
brave enough to attempt fucking her, at least not yet. He pulled his finger
out and tasted it. It tasted as good as she smelled. He licked it again, and
put it up to her tiny little puckered pink asshole. He'd never played with
any of his girlfriend's assholes becuse they wouldn't let him, but he always
wanted to try it once. He pushed the finger slightly against the crinkled
hole, and finally it gave way. Up it went into her tiny ass. He began
corkscrewing his finger around as he pushed deeper into her bowels. The sight
of his finger against her cute little ass cheeks made him shiver. He just
had 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 going
to 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 the
opening and pushed his hips forward slightly. He watched as the head slowly
disappeared into Carla's young, tight pussy. He pushed a little farther and
felt her hymen blocking his way from entering her any further. Her pussy was
so tight and felt so good, and the sight of his dick stuck into this almost
hairless pussy alomost made him lose control, but he didn't want to try to
push through her cherry. He reluctantly pulled out of her pussy, and was going
to pull his pants back on, then decided to try her asshole. "No cherry there
to break" he thought, and since his dick was so slick now, it might slide right
in. He put some saliva on her asshole anyway, just for the hell of it, and put
his swollen cockhead up to her tiny anus. The head of his dick was much bigger
than her little hole, but he'd heard of others doing this, so he decided he
would try it. Pushing harder and harder against the tight hole, it finally gave
way and allowed his prick to sink deep into her rectum. The tightness of
her ass was unbelievable, and almost before it started, it was over. Steve
had to pull out almost immediately and came all over his own legs. He grabbed
a 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 of
about 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 or
someone if you didn't straighten out real soon." Steve said with a convincing
tone of aggravation and and concern. "Geeez, don't say nothin to anyone about
it. 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 my
way" Steve said shaking his head, and feeling a new sense of glee. He thought
to himself as he started the car, "Man, this is the best investment I ever made
in my life. I can't wait to try this out on a few of those stuck-up bitches
at 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'll
hafta do this again" he smiled to himself and drove off with many plans in
his head about who was next to discover his new found way with women.
