ROAD TRIP

The year was 1951. I was nineteen and living at home attending a local junior college. Like most boys my age, I was obsessed with sex. I bought some small black and white photos of naked girls from a guy at school and spent hours jerking off staring at their tits and patches of fur between their legs. I had been on a few dates, but the furthest I ever got was with Mary Ellen Tate who let me feel her tits through her blouse. I got so excited, I came in my pants.

I had never paid much attention to my younger sister, Kathy. That changed the night I walked in on her as she was stepping out of the shower. Her tits weren't big, but seeing those perky pink nipples poking out and a dark gash peeking through the strip of light brown curls covering her pussy made my cock jump to attention.

Kathy was the first naked girl I had seen in the flesh. It was only for a second, but it was enough. She pulled a towel in front of her when she saw me. I apologized and ran to my bedroom where I pulled out my cock and sprayed ropes of cum all over the parquet floor. I knew there was something perverted about jerking off to my sister, but I couldn't help myself. I had seen her tits and pussy.

After that night, I took more notice of Kathy. She had just turned eighteen and was a senior in high school. My sister was a tiny girl, barely five feet tall, and pretty with blonde hair and big blue eyes. Her tits weren't much more than swells on her chest, but her shapely ass filled out a pair of shorts nicely. She didn't have a boyfriend and had only been on a few dates. I assumed she was pretty naive about matters of sex.

Despite the fact that she was my sister, I continued to jerk off to images of her naked body. One night I slipped into her closet to watch her undress. I almost came in my pants for a second time when she bent over and pulled off her panties. Her swollen pussy hung between her thighs like a ripe peach just below two perfectly round and creamy smooth ass cheeks.

Kathy turned around until she was facing me, although she didn't know it. She played with her perky nipples. My poor cock was about to rip through my pants. I pulled it out and began to pump. Kathy dropped a hand between her legs and rubbed her pussy. It was more than I could handle. My cock exploded, spraying cum all over her closet floor. She finally pulled on a night shirt and went to the bathroom, allowing me to escape.

I became obsessed with my sister and began sniffing her soiled panties. I hid in her closet several more times to see her naked and watch her masturbate. Sometimes she did it standing up and other times she lay on her bed and fingered her pussy. It always ended with her gasping and shaking. I often had a pair of her panties wrapped around my cock as I watched.

Kathy might have remained a masturbation fantasy if it hadn't been for the family vacation that summer to Cape Cod. My Uncle Charlie had a house there. It was a two day trip. The first night, we stopped at a motel in Pennsylvania. We all had to share a single room with two double beds. Kathy and I were in one bed while my parents slept in the other.

Kathy came out of the bathroom wearing a nightshirt with two perky nipples poking dents in the front. I slipped under the covers to hide the hard-on making a tent in my pj's. Kathy bent over to pick up her towel. Her night shirt rode up and exposed a pair of blue cotton paintes wedged into the crack of her ass. Pre-cum was already leaking from my throbbing cock.

I needed relief in the worst way. Once the lights were out, I rolled onto my back and gently began stroking, trying not to disturb Kathy. I was well into my fantasy of sucking her tits and fingering her pussy when she shifted on the bed. Her ass cheeks pressed against my thigh. I assumed she was innocently moving around, but if she could move so could I.

I rolled onto my side and draped my arm over her body as though I was doing it in my sleep. My hard cock poked out from my pajama bottoms and wedged between her ass cheeks through her panties. Kathy didn't move or respond. If she was awake, she didn't seem to mind having my cock wedged between her cheeks. She couldn't be so naive as to think it was normal.

I decided to see how far I could go before she stopped me. If she got upset I would apologize and say I was dreaming. I slid my hand under her night shirt and slowly inched it up her stomach until my finger brushed across her hard nipple. My cock jumped. When I rolled her nipple between my thumb and forefinger, I heard Kathy moan. Was she awake? I didn't know and I didn't care.

I let my hand slide down her stomach and across her panties to the swell of her pussy. I could feel the heat pulsating through the thin cotton. I began to rub. Kathy moaned again. Any doubt about whether or not she was sleeping was erased by what happened next. She moved her hand over mine and directed my fingertip to a tiny nub pushing through the cotton of her panties. I didn't know what a clit was back then, but she clearly wanted me to rub her there.

She moved with the motions of my finger. Her breathing became heavier and more erratic. Soft moans escaped from her throat. I continued to rub the tiny nub in circles, applying more pressure and going faster. She grabbed my forearm, digging her fingers into the skin. Her body trembled. She bit her lip and stifled a scream. I kept rubbing and she kept shaking.

I thought it was over, but it wasn't. Kathy took my hand and pushed it under the waistband of her panties. My fingers slid through the soft curls covering her mound until they reached the searing heat of her pussy. She guided my middle finger between her moist folds. Did she want me to put my finger inside her? She must. It was the only explanation.

I had never fingered a girl. I tried to find her opening but was unfamiliar with the anatomy. My sister came to the rescue and put my middle finger where she wanted it. I pushed and felt it go deeper. She was tight, but seemed to stretch as I inched my way into her body. I buried it all the way to the knuckle. The heat of her pussy throbbed against me. I pulled it out and pushed it back in. I did this again and again. I could feel her moving with me.

I couldn't believe I was fingering my sister. My poor cock was throbbing and still pressed tightly between her ass cheeks. It was going to explode at any second. Kathy's breathing got faster. I felt her trembling. She pressed her face into the pillow to muffle a scream. Her pussy clenched and spasmed against my finger. Sticky secretions dribbled over my hand.

My head became dizzy. I knew this feeling. It happened when I masturbated. My balls shrunk. My cock swelled. Hot cum exploded from the tip. Spurt after spurt shot up her back. My finger was still buried deep inside her pussy. I felt her shudder one last time, and then she went limp. Cum continued to ooze from my cock and soak into the back of her panties. When it was over, I pulled my finger out and sucked it into my mouth, savoring the taste.

The next morning was awkward. Kathy avoided me unless our parents were around. I wanted to talk to her about what had happened and find out how she felt. Was she upset with me? Did she like it? Did she think it was perverted? I finally cornered her when Mom was in the bathroom and Dad was packing the car. I could see fear in her eyes. She knew what I was going to ask.

"Kathy, we have to talk about last night. We can't pretend like nothing happened. When you pressed your butt against me, did you do it on purpose?"

Kathy looked down and shook her head. "No. Um, that was an accident. Do we have to talk about this?"

"Yes. What did you think when I put my arm around you and pressed against you? Why didn't you stop me?"

"I don't know. I thought maybe you were asleep, but I wasn't sure. I knew what was pressing against my butt, but I didn't want to disturb you, and, um, well, I had never felt anything like that."

Kathy turned red.

"When I slid my hand under your shirt you must have known I was awake. You could have stopped me then."

Kathy lifted her eyes to mine. "I was confused. Jenny's always talking about how good it feels when her boyfriend touches her like that so I was curious, and with your thing pressing against me, I was feeling things I had never felt with a boy. I wanted you to touch me."

"What about when I put my hand between your legs? You liked that, didn't you? It's why you showed me where to rub."

Kathy nodded and looked down. She was clearly embarrassed and didn't want to talk about it so I let it go.

We finished packing up the car. I couldn't keep my eyes off Kathy's crotch and the tiny swell bulging from the white shorts she was wearing, knowing that just beneath two thin layers of cotton was the pussy I had fingered last night. She caught me looking once and quickly turned around, giving me a nice view of her tight ass cheeks stretching the fabric covering them.

I was already sporting a hard-on when we climbed in the back seat. This was in the days before seat belts. Kathy said she was tired so Mom gave her a blanket. She threw it over our laps. Kathy pulled it up to her neck, rested her head on my shoulder, and closed her eyes. Our thighs were touching. My cock twitched. It didn't take much in those days to get me excited.

After last night and our discussion this morning, I was curious to find out how my sister would react to anything else I might try. I dropped a hand onto her thigh. Rather than move it, she shifted in her seat, turning slightly away and opening her legs. It felt like an invitation. My fingers moved up her inner thigh. She spread her legs wider. It was definitely an invitation.

There was no way Mom and Dad could see what we were doing under the blanket, not even in the rearview mirror. I cupped my hand over her mound. Kathy squirmed against me. She unsnapped her shorts and pulled down the zipper, then guided my hand into her panties and pressed my finger against the tiny nub at the top of her slit. I rubbed it in circles.

Kathy's legs began shaking. She turned her face into my shoulder and gasped. I looked in the front seat. Mom and Dad had their eyes focused on the road and were discussing a song on the radio. I slipped my finger through her folds and pushed it into her pussy. She slumped down, humping against me as my finger moved in and out. Her pussy exploded, drenching my hand with sticky secretions. Kathy's squeal was loud...too loud.

I quickly pulled my hand out of her panties. Kathy sat up as Mom turned to look at us.

"Is everything alright back there?" Mom asked.

"Uh, yeah," Kathy answered. "I couldn't fall asleep and I'm bored. There's nothing to do."

"Yeah," I said, playing along. "Me too."

"I know it's a long trip," Mom said. "We're going to stop in an hour or so for a bathroom break."

My cock was about to explode. A huge wet spot had formed on the front of my bermudas from all the precum leaking out. Once Mom had turned her attention back to Dad and the road, I unzipped them and pulled out my hard cock. I didn't care if Kathy knew I was jerking off under the blanket. I needed to get off.

I began stroking, knowing it wouldn't take much. That's when I felt Kathy's fingers brush against mine. I let go. She rubbed her hand over my hard flesh, moving it up my length and tracing her fingers around the ridge of my crown. She found the little slit on top where precum was leaking out and rubbed a fingertip through it.

"Is this the stuff that makes babies?" Kathy whispered.

I shook my head. "No. There's a lot more when that happens."

We kept our voices low so Mom and Dad couldn't hear. Fortunately, the radio in front was loud enough to drown out any sounds.

"Like the stuff you shot up my back last night?"

I nodded.

"Is it going to happen again? Is that why some stuff is leaking out?"

"It will if someone makes it happen. Do you know what a handjob is?"

Kathy nodded. "Sort of. Jenny gave one to her boyfriend. She said white sticky stuff comes shooting out."

"That's right. That's what makes babies."

"Can I see it?" Kathy asked. "Your, um, thing."

I held out the blanket so she could see my throbbing cock. She rested her head on my chest to get a better look. Her fingers continued to trace the contours of my hard flesh and the sticky precum leaking out from the tip. I showed her how to wrap her fingers around my cock. Her tiny hands barely fit.

"Do you want me to show you how to give a handjob?" I asked.

Kathy nodded. I helped her stroke by moving her hand up and down. She kept her eyes glued to my cock as she pumped.

"Move your hand faster and squeeze a little harder."

She did. I knew I was close, but it happened so fast I didn't feel it coming. A jet of hot cum shot up my length and erupted from the tip. It bounced off Kathy's cheek and into her hair. She continued to pump. More shot up her arm and splattered her top. Some landed on her thighs. The last few drops oozed over her hand.

"How are you kids doing back there?" Mom asked.

We quickly pulled up the blanket and pretended to be asleep. Mom turned around to look at us, then turned back towards Dad.

"They're sleeping like babies, honey. Do you mind if I put my head in your lap and get some shuteye?"

Dad chuckled. "The last time you did that, you didn't get much sleep as I recall."

"Are you complaining?"

Mom's head fell below the back of the front seat. Kathy pulled her cum drenched hand from under the blanket and examined it.

"Wow. This stuff really makes babies, huh?" She whispered.

I shrugged my shoulders. She stuck out her tongue and tasted it, then licked some from her hand.

"It tastes a little weird," Kathy giggled. "That's gross isn't it?"

No more gross than when I licked pussy juice from my finger, but I didn't tell her that. It was then that I realized Mom wasn't exactly sleeping. We could hear soft sucking and slurping noises coming from the front seat. Dad was biting his lip and trying hard to concentrate on the road. It took me a second to figure out what was happening. I knew girls did things like that from locker room talk, but Mom? Did she really have Dad's penis in her mouth?

Kathy heard the same noises but was clueless. She looked at me. "What's Mom doing? Is she chewing gum in Dad's lap?"

I shrugged my shoulders. I didn't want to explain it to her in the car. The noises got louder. Dad's eyes grew big. Suddenly the car swerved. His face scrunched up. I knew that look. He was shooting. Was he doing it in her mouth? Mom answered that question when she sat up, wiped her lips, and swallowed. I was shocked.

At the rest stop we got out to pee and get something to drink while Dad put gas in the car. It was the first time I really looked at Mom and realized she was quite attractive. She was petite and had blonde hair and blue eyes just like Kathy. Her white shorts fit snuggly to her shapely ass. Her tits were kind of average, but for the first time I wondered what they looked like naked. Then I looked at her red lips and imagined them wrapped around Dad's hard cock.

I ran into Kathy coming out of the bathroom.

"I have a question, Mike. I asked Mom if I could have some gum. She told me she didn't have any. If she wasn't chewing gum, what was doing with her head in Dad's lap?"

"You won't believe me if I tell you."

"Why not?" Kathy asked.

"Because she had Dad's penis in her mouth. She was sucking on it."

Kathy's eyes got big. "No she wasn't. You shouldn't joke like that."

"I told you that you wouldn't believe me. It's called a blowjob. I heard guys talking about it in the locker room. Instead of using a hand to make a guy shoot, the girl uses her mouth."

Kathy's jaw dropped. "Mom really had Dad's penis in her mouth? What happens when he shoots?"

I raised my eyebrows and smiled knowingly. Kathy put her hand over her mouth.

"You have to be kidding. Dad shot in Mom's mouth?"

I smiled and nodded my head.

"Where did she spit it out?"

"Who says she did?"

Kathy was shocked. "You mean...?"

"Yes. When Mom sat up, I saw her wipe her lips and swallow. What else could it have been?"

Kathy shook her head. "I didn't even know girls did things like that, much less swallow it. Not that it tastes that bad, but, you know, it's our mom."

"You want to hear something else you didn't know? Guys do it that way to girls too, using their tongues instead of their fingers."

Kathy gasped. "You mean they lick girls down there where it's all gooey? Do you think Dad does it to Mom?"

"Probably."

"Oh wow. I have so much to learn.

Dad waved at us to get back in the car. Once again, Kathy snuggled next to me and pulled the blanket over us. Mom turned around.

"We still have a few hours before our next stop. Try to get some sleep."

Mom rested her head against Dad's shoulder and closed her eyes. Kathy's hand slid into my lap and rubbed my bulge which immediately jumped to attention.

"I want to see it again," she whispered.

I unbuckled my bermuda's and pushed them down my thighs along with my Jockey's. My cock sprung up from my lap. I held the blanket out far enough so Kathy could see. She slid her head to my chest to get a better look. Her fingers curled around my cock. I sat back and closed my eyes, preparing to enjoy another handjob. Instead, I felt her kiss the tip of my knob. My cock jumped.

Kathy turned her head and looked up at me, her hand still wrapped around my cock. I could see the desperation in her eyes and was pretty sure I knew what she wanted. She was seeking permission to put it in her mouth. I nodded my head. She turned back towards my cock, pushing out her tongue and licking the swollen knob. Then she slid her lips over the ridge of the crown.

I kept the blanket high enough to hide what she was doing. If Mom happened to peek back I would tell her Kathy fell asleep in my lap, but Mom appeared to be gone on Dad's shoulder, and Dad couldn't see that far down in the rear view mirror.

Kathy took more of my cock between her lips, but her tiny mouth could only handle half of my seven inches. I saw her cheeks puffed out and wondered what she was doing. Kathy lifted her lips from me and sat up, wiping away spittle that had dribbled down her chin.

"I'm not sure how to do it," she whispered. "I tried blowing on it but that didn't seem to work. You did say it was a blowjob, right?"

Having her lips wrapped around me and my cock buried in her wet mouth was more than exciting, but Kathy had a point. It didn't seem like blowing on it was the right thing to do.

"I don't know, but Mom sounded like she was sucking on Dad's. I think it's supposed to slide in and out, kind of like the same motion when you move your hand up and down."

"Will it make you shoot in my mouth?"

"It would if I didn't pull out."

Kathy bit her lip and averted her eyes, looking embarrassed by what she was about to say.

"Um, is it okay if I don't want you to pull out?"

That statement alone made my cock jump. I nodded, hardly able to believe it. Her lips slid back down my shaft, gripping me tightly. This time she moved them up and down my length. I put my hands on her head and moved with her. She made soft sucking sounds as my cock slid in and out. Spit was drooling from her lips and running down my shaft onto my balls.I knew I wasn't going to last much longer. I moved with more urgency, bouncing my cock against her throat on each thrust and making her gag. I thought she might pull away because it was getting too rough, but she didn't. If anything, she was attacking my cock more aggressively. Then it happened. I thrust up between her lips and grunted. Hot cum sprayed like firehose directly into my sister's mouth.

Kathy was caught by surprise. She coughed as it shot against her throat. Cum poured over her lips and oozed out of her nose. My cock fell out and splattered her face. Kathy got her lips back around me as the last few spurts filled her mouth. She sat up with cum drooling down her chin, then closed her lips and swallowed what was left. She looked down at my cock, which was still hard, and wrapped her fingers around it.

"Will it shoot again if I keep doing it?"

"Um, yeah, but it might take a while."

I was wrong. Kathy lowered her head and took me back between her lips. Having her warm wet mouth sliding up and down my shaft, her tongue swirling across my hard flesh, and the sound of her moaning at the obvious pleasure she received from sucking my cock had me spewing for the second time in five minutes. This time she kept her lips pressed tightly against my shaft until I was finished. She sat up and gulped it all down just like Mom had done with Dad.

After recovering, I realized Kathy's eyes were closed. Her head was thrown back. Her breathing was heavy. I noticed her arm moving. She had a hand in her shorts and was masturbating. I lifted her top and tweaked her nipples with my fingers. She went off like a powder keg. She buried her lips against my shoulder to muffle her scream. Her body twisted and jerked in a series of uncontrollable spasms.

I grabbed her arm and lifted her hand to my mouth, sucking on her sticky fingers which dripped with the taste of pussy. Then I slid my hand into her shorts and buried a finger up her cunt. She humped against me as I fucked it in and out. Minutes later she exploded with a second climax, twisting and turning in the seat as pussy juice oozed over my hand and fingers.

"Are you kids alright back there?" Dad asked.

I caught his eye in the rear view mirror. "Um, yeah, Dad. I think Kathy was having a nightmare, but she's okay now, right, Kathy?"

"Uh, yeah. I was dreaming about sharks."

"Don't worry, Honey," Dad replied. "There won't be any sharks where we're going."

Kathy managed to wipe the cum from her face just as Mom stirred awake and turned around.

"Did you kids get a nice nap?" We both shook our heads. Mom smiled. "Good. We're going to stop for another bathroom break soon."

The bathroom was a single seater. Mom and Dad used it first, then headed into a nearby store to pick up food. Once they had disappeared, Kathy asked me a question.

"Do guys really do what you said? You know, kiss a woman down there between the legs?"

"Yeah, I'm pretty sure. Sometimes women do other women that way, too. You know what a lesbian is, right?"

"Yeah, but I thought they just kissed and fingered each other. Have you ever wondered what it would be like to do it that way to a girl? Do you think it's gross?"

I had jerked off many times smelling Kathy's pussy from the crotch of her panties, so no, I didn't think it was gross. I would be in heaven.

"Yeah, I mean, I've wondered about it. I don't think it's gross."

Kathy fidgeted with her forearm and looked down like she was embarrassed.

"Would, um, you do it to me if, um, if I let you?"

Was that an offer? "Of course, Kathy. I mean if you wanted me too."

She looked up and I could see the pleading in her eyes. This girl was desperate.

"Would you do it to me now, in the bathroom? No one else is here and Mom and Dad have already gone."

Being the gentleman I am, I agreed. I followed her into the bathroom. It was barely big enough for a sink and a toilet. Kathy peeled down her shorts and panties, stepping out of them. She leaned against the sink and spread her legs. I squatted in front of her and stared at her ripe young peach covered with a strip of soft brown curls. The pink folds of her pussy were visible through the dark gash down the middle.

Never having eaten a girl, I was not sure what to do, but I had an idea of what was involved. I leaned forward and kissed her pussy, then opened my mouth and clamped my lips over her swollen mound, ignoring the tickling of her pubic hair. I slid my tongue along her gash, pressing the tip against it. She opened for me. The taste of her pussy filled my mouth as I probed deeper, parting the folds and pushing into her entrance. Kathy moaned.

"Oooohhhh...uuuuuhhhhhhh..."

My tongue pushed deeper. I moved it in and out. Juices seeped into my mouth. I fluttered my tongue inside her and sucked on her pussy, making loud noises. Kathy put her hands on my head and humped my mouth. I slid my hands around her body and cupped her ass cheeks. Her legs began shaking. Her knees got wobbly. Her pussy exploded. Juices gushed over my tongue and dribbled down my chin.

I pulled my mouth away and slid a finger up her cunt. I watched it slide in and out, making wet squishing sounds from all the juices sloshing around inside her. I noticed the hard nub at the top of her slit peeking out at me. I flicked my tongue across it. It set off an explosion even more violent than the last one. Her scream reverberated off the walls. Her body bucked and jerked and twisted. Juices dripped from my hand and coated her thighs.

My cock was about to explode. There was no way I could make it back to the car before I unloaded my balls. I stood and pushed down my shorts. My throbbing cock bounced free. I bent my knees and placed the tip against Kathy's pussy, sliding it up and down along her slit. She reached down and held it so it would rub against her clit.

The angle was awkward because she was so short, but I didn't care. I continued to slide between her folds and over her clit. Her hand pressed down hard on me. The next time I thrust, it slid into her folds rather than along them. I was too far gone to do anything but finish. Kathy was too. My knob pushed into her opening, but hit some kind of barrier to keep it from going deeper.

I kept thrusting the head in and out. Her body trembled. We both went off at the same time. Kathy screamed. I grunted. Hot cum spewed into her opening. Her body jerked and bucked wildly. I kept spewing spurt after spurt against her pussy. It dripped onto the floor and streamed down her legs.

Kathy's orgasm got a second wind. Her legs shook and her knees became wobbly. On my next thrust, the barrier that had been stopping my cock from going deeper disappeared. Kathy squealed. I plunged inside her, stretching her open. I was buried deep when she came back to earth. Her pussy twitched and clenched against my cock. She opened her eyes and looked up at me.

"I'm not a virgin anymore, am I?"

I nodded my head and began to pull out. Kathy objected.

"No. Stay in me."

She reached between her legs and rubbed her clit. I slowly moved my cock in and out of her pussy. It was still hard as a rock. Kathy looked down and watched it fuck her. Two fingers flew across her clit. Her body stiffened. A scream pierced the air. Her pussy gripped me tightly as it pulsed and released more juices that dripped from my balls.

Kathy threw her arms around my neck. I cupped her ass cheeks, lifting her onto the sink. She pulled her legs in the air. My cock pounded into her again and again. My balls slapped wetly against her asshole. I pushed up her top and pinched her nipples. Kathy exploded, oozing more juices onto my cock and down my balls. That set me off. At the last second, I realized what I was about to do and pulled my cock from her pussy, wrapping my hand around it.

"AAAAARRRRRGGGGGHHHHHHHH..."

Hot cum flew from the tip. It shot across her body and landed on her face. More splattered her tits and stomach. The last few drops oozed over her pussy. Kathy slid her fingers through the sticky mess and rubbed her clit. She squealed as another climax exploded from her pussy. Moments later, there was a knock on the door. It was Mom.

"Kathy, are you in there?"

She did her best to control her breathing. "Yes Mom. Why?"

"We're going to leave soon. Have you seen your brother?"

"No. I've been in here."

"Are you feeling alright? You've been in there a long time. I thought I heard you making noises."

"Um, yeah. I think I had something to eat that didn't agree with me, but I'll be okay now."

"Okay. Your dad's having a tire changed, but we'll be ready to go in about twenty minutes."

Kathy, leaning against the sink, looked down at my cock. It was still hard. She pulled off her tee shirt and stood in front of me naked, her swollen nipples poking out from the small swells on her chest.

"Do we have time to do it again?"

I had already cum twice, five times that day if you count the three in the car, but I wasn't about to pass up the opportunity being offered. I slipped back inside her. Her pussy clung to my cock with a firm grip, heat pulsating from the walls of her cunt. I wanted to stay there forever. I grabbed her girlish ass cheeks and slid in and out of her pussy. Kathy rubbed her clit with one hand and pinched her nipple with the other.

"Oh god...here it comes...UUUNNNNGGGGGHHHHH..."

Her pussy exploded, clenching my cock in a series of spasms and sending a flood of cunt juice down my shaft and over my balls. I continued to pound into her, jerking her body up on each powerful thrust. Kathy had another climax and then another, but I never stopped. After ten minutes, I could feel cum churning in my balls. I was about to pull out when Kathy said something that surprised me.

"You can shoot inside me if we do it standing up. Jenny said you can't get pregnant that way. It won't go all the way in like it does when you're lying down."

I didn't know if it was true, but I wasn't going to argue. Kathy slid off the sink. I had to bend my knees to keep my cock inside her. I slammed into her hard and fast, lifting her onto her toes on each thrust. My head got dizzy. My balls shrunk and my cock swelled. I grabbed her ass and buried my cock deep inside her pussy.

"AAAARRRRGGGGGGGHHHHHHH..."

Hot cum shot up the length of my cock and exploded into her cunt. Spurt after spurt pumped into her until it was seeping out from around my cock and running down her legs. Kathy dug her fingers into my shoulders. A scream rattled the window. I grabbed her ass and lifted her light body off the ground, my cock still buried deep inside her pulsating pussy. She wrapped her arms and legs around me. We held each other tight as we slowly came back to earth.

That night Kathy and I had to share a bed again. Once the lights were out, the room became pitch black. She snuggled close. We kissed for the first time. It was tentative at first but soon our tongues were dancing in each other's mouths. I reached under her night shirt and pinched her nipples. My hard cock rubbed across her pussy as she squirmed against me. She kissed my neck, and then my chest and then lower. My cock slid between her lips.

Kathy became more experimental, using her mouth and tongue to stimulate every nerve ending she could find. She bobbed her head up and down, sucking and slurping like a wanton whore. I wasn't going to last long. Suddenly her body stiffened and began shaking. My cock fell from her mouth as she bit her lip to stifle a gasp. Kathy had been fingering her pussy while sucking me and had a climax.

I pulled her up and kissed her hard on the lips. Kathy slipped off her panties and lifted her leg, guiding me to her opening. It was a little awkward doing it facing each other, but I managed to get my cock into her steamy cunt. I rolled over on top of her. We kissed and fucked, trying not to make too much noise.

Kathy bit my shoulder when her next climax hit. I slowed down, wanting to make the moment last. My cock slid in and out of her quivering pussy with long steady strokes. She pulled her legs back so I would go deeper. We kissed and fucked in a steady rhythm. I picked up the pace. Kathy rubbed her clit and had another climax, this one a little too loud.

"Kathy, are you okay?" Mom asked from the other bed. We stopped moving, my cock still buried deep inside her.

"What's the matter, honey?" Dad asked.

"I thought I heard Kathy shriek. Maybe she was dreaming out loud. I do that sometimes."

"Yeah, she did it in the car today. She was dreaming about sharks."

"Then that explains it. The kids seem to be sleeping soundly so it's nothing to worry about."

"In that case, since we're awake, maybe we should take advantage of the situation," Dad suggested. "I do owe you a favor after what you did to me in the car."

"No, honey, we shouldn't. What if...oooooohhhhhhhh..."

We could hear Mom moaning and wondered what Dad was doing to her. She answered our question when we heard her whisper to him.

"Oh fuck, baby, you eat pussy so good. Oh yes...lick me...ooohhhhhh..."

"Do me that way," Kathy whispered in my ear. "Please."

I didn't need a lot of convincing. I slid my head down Kathy's body and smelled the musky fragrance of her pussy. My tongue shot out and parted her folds. She squirmed against me as I clamped my mouth around her swollen plum, licking and sucking the juices from her body. My tongue found her clit and fluttered across it. Kathy tried to suppress a squeal, but failed. The only thing that saved us was Mom's loud climax which happened simultaneously.

"Get up here and fuck me," we heard Mom say to Dad.

Kathy pulled me up her body. We kissed, sharing the taste of her pussy. She guided my hard cock between her thighs and into the opening of her cunt. She put her lips to my ear and whispered words I never thought I would hear my sister say. It was like she was trying to imitate Mom.

"Fuck me."

I thrust hard and felt my cock plunge into her steamy passage. The walls of her pussy gripped me tightly. I slammed into her again and again, driving my cock deep into her cunt on each thrust. Kathy's fingers clawed at my back. My balls slapped against her asshole, making subtle smacking sounds from the juices seeping out of her pussy.

There was something so wrong yet erotic about Dad fucking Mom in the same room where Kathy and I were fucking. We became reckless, no longer worried about the noise we were making. Mom and Dad were making even more noise. Their moans and gasps got louder. Filth began spewing from Mom's mouth.

"Fuck me, John...harder. Shove your big hard cock up my dirty little cunt."

Kathy, taking her cue from Mom, whispered in my ear, "Fuck me, Mike...fuck my hot pussy."

Hearing Kathy talk like that had my head spinning. I picked up my pace, slamming into her hard and fast. I was getting close. On the other bed, I heard Dad grunt and Mom yell.

"Yes, baby, shoot it inside me. Fill my pussy with cum."

Mom shrieked. So did Kathy. She scratched and clawed at my back. Her heels pounded my ass cheeks. It was too much for me. I felt my cock swell. I began to pull out, but Kathy wouldn't let me. She grabbed my ass, holding me inside her. Once again, she mimicked Mom.

"I want it in me. Fill my pussy with cum."

I couldn't have held back if I tried, which I didn't. I thrust deep and unleashed a powerful blast of cum that sprayed from my cock like a stream of pee. This sent Kathy spinning into another gushing climax. I pumped stream after stream of cum into her pussy until it was sloshing around inside her and dripping from my balls. I had never cum so hard in my life, and I did it inside my sister's cunt, knowing it might make her pregnant.

We lay there breathing hard, my cock still inside her cum-filled pussy. Mom and Dad had been so caught up in what they were doing that they hadn't heard us. Kathy pulled my lips to hers and shoved a tongue in my mouth. We kissed as her pussy clenched and twitched against my cock. I began to pull out. She clamped her legs around me.

"No," she whispered. "Stay inside me."

Amazingly, I was still hard. Kathy squirmed against me, rotating my cock around inside her pussy. She slid a finger to her clit and rubbed. Her breathing got heavier. I knew she was about to climax. I didn't know if Mom and Dad had fallen back asleep, but I didn't want to take a chance. I kissed her to muffle her squeals. When she recovered, Kathy moved her lips to my ear.

"Fuck me again."

She was insatiable, but so was my cock. I moved it in and out, slowly at first and then more aggressively. I rolled onto my back and pulled her on top of me. I found myself laying in a big puddle of cum and cunt juice. Kathy and I kissed some more as she rode me, lifting her ass in the air and slamming her pussy down the length of my cock again and again.

"Fuck me, fuck my pussy," she whispered between gasps and moans.

I grabbed her ass cheeks to guide her fucking motion and rammed my cock up inside her each time she came plunging down on me. Pussy juice had matted my pubes and was dripping from my balls. Kathy rubbed her clit against the base of my cock until she was shaking with another climax. She bit my shoulder to stifle a scream.

I was about to shoot again but this time I wasn't going to do it in her pussy. I pulled out and pushed her head down. Kathy didn't hesitate. She took my cock deep into her mouth. I grabbed her head and fucked it in and out between her lips, slamming against her throat and making her gag. Spit poured from her lips and ran down my balls. I grunted. Spurt after spurt of hot cum sprayed into her mouth. She swallowed it all.

The next day we reached Uncle Charlie's house for three weeks at the beach, but that's another story for another time.
