During our stay in a tourist city, I have accidentally awakened my sister's sexual desires. She is into some stuff I'm not too comfortable with, but I played along fearing she would blackmail me and cause herself harm. Now, I'm beginning to enjoy her same fetishes.
I didn’t get any chances to stay alone with my sister in the next couple days. The weather had gotten worse. Going to the beach was out of the question and the house we were staying in wasn’t big enough to fuck without being heard.
My mom had been looking for museums and monuments online to visit. It was a real shame we couldn’t go for a swim. I really would have loved to see mommy in her bikini, now that her tan lines had disappeared.
At lunch, mom announced: “We are going to visit the Church of the Holy Trinity this afternoon”.
“What’s so interesting about this church, mom?” I asked.
Stacy kept staring at her phone, indifferent to this conversation.
“Oh, you know, I have read the tourist guide on this website, you know, and they’ve got statues and paintings and such”
“Every church in this country has those. What’s so special about these ones?” I replied absent mindedly.
“Oh, you can’t possibly describe such wonders with words. You have to be there and see it with your eyes to understand”
“That sounds lame” uttered my sister.
“Well, I know this really isn’t your cup of tea, and this season I wasn’t planning on visiting any monuments either, but we may as well make the most of it. Who knows, you may even learn something about history”
“Yeah, speaking of history, I have to study. Spring break is almost over, and I don’t wanna drop out of high school like Julian”
“Yeah, I’ll pass as well. If the weather ain’t good enough to go to the beach, it ain’t good enough to visit churches either”
“Well, I don’t wanna spend my vacation locked up between these walls. I’m going. If you don’t want to come with me, I’m leaving you home alone” she threatened.
I made eye contact with my sister. Her eyes almost popped out of her skull for an instant but she acted like she didn’t care.
“Yeah, we’ll take care of eachoth-“ Under the table, my sister kicked me in the knee. “I mean, we can take care of ourselves.”
By noon, my mom had finished dressing to go out. She wore a skin colored blouse which looked pale compared to her tan, and a skirt the color of her eyes. She leaned forward to kiss Stacy goodbye, leaving a lipstick mark on her forehead. From the window, we watched her struggle to keep her balance on her high heels, waiting for her to disappear in the distance.
Once our mother was gone, I approached my sister from behind, pressing my boner against her skirt. She spread her legs and grabbed my erection from underneath her skirt, pulled it between her thighs, and shook her hips.
“Let’s move away from the window” she said.
She grabbed my hand and brought me to her room, then she rummaged through her closet.
“There it is” she exclaimed, holding a can of pringles in her hand, which made a sound like that of maracas when shaken.
“What are you gonna do with that?” I asked.
She knelt before me and unzipped my pants. I felt relief as my cock was released from the cage it was pushing its head against.
“I wanna jack you off, bro. But I shouldn’t touch your penis directly. That would be incest”
“Don’t give me that -it’s wrong to have sex with your siblings- bullcrap. You have taken my cock in the pussy before, sis”.
“That’s why I made a replica of my pussy out of salt dough. It will be just like the real thing” She removed the can’s lid, revealing a fleshy-looking pussy inside.
“It doesn’t look like yours, sis. Your pussy is definitely looser than this thing”
“If you can handle five minutes of it, you can have the real thing. I’m gonna time you. Don’t you dare cum before the time runs out.” she said smirking.
“Fine. I accept your challenge” I declared.
She whipped out my throbbing cock and pressed that improvised fleshlight against it. She started to stroke my dick hard with it. However, the dough was too soft to withstand that motion. It crumbled against my dick in just a few strokes.
“I just broke your little toy, sis. Do I get to fuck your pussy now?”
“Not so fast. You have just torn my hymen again. The real fun begins now”.
The next thrust set my cock on fire. The sensation was like rubbing alcohol on an open wound.
“What the fuck did you put in there?! A fire ant hill!?” I yelled.
“No, that is in your cereal box. These are just rice grains soaked in vinegar and coarse salt. Nothing your cock can’t take for five minutes”
That burning sensation on my dick was growing, and so was my pleasure. The clock kept ticking.
“I’m gonna make you pay for this, bitch!”
“Oh, I’m counting on it.”
It was a good thing I was phimotic. I would have hated having to pee a grain of rice or salt as big as a kidney stone out of my dickhole.
Eventually, the precum around my dick formed a thick protective layer, shielding it from the vinegar’s acid. When time ran out, I was no where near close to orgasm, but my dick was hard as marble.
“Alright, I’ll let you fuck me” said my sister as she lifted up her skirt and got on all fours, turning her back to me.
“But you’ll have to catch me first!”
Stacy blew me raspberries and ran on all fours to the kitchen. I chased her with my pants down my ankles, dick in hand. When I arrived, she was looking for something in the cupboard.
“No, forget about it! No more horsecrap with vinegar! Just you, me, and my raging cock”
“Don’t worry. These are not for you they are for me” She picked up a bag of raw chickpeas.
“Since you broke my last toy, I’m keeping this one for myself” She opened the bag and spilled its content on the floor. Next, she knelt on the chickpeas she spilled.
“Come give me your dick, brother. I want it in my mouth”
I approached her, and she opened her mouth wide.
“Here comes the airplane. Swallow it all like a good girl”
She licked the mixture of precum and vinegar that was dripping from my foreskin. She pinched my tip a little with her teeth. I slapped her lightly across the face.
“A good dog shouldn’t bite his owner, neither should a little bitch like you”
She bit her lips and started to work on my shaft.
She had improved a lot since last time she sucked my cock. Her hand grabbed my balls tightly. She put most of my dick in her mouth without my help. She rubbed the tip against her gums. Her cheeks bulged up as her tongue moved my cock left and right in her mouth. The tip of her tongue twirled around my cock, sucking it dry of all the precum. Had she chosen to, she could have made me edge for hours with this technique, but I wouldn’t let her.
With every thrust of my dick, she had to balance herself back and forth on the chickpeas she had spilled. Their hard and pointy ends were digging in her knees.
“Sis, we better stop. The chickpeas are going to leave bruises. If mom sees them, she is gonna ask you questions”
She replied without pulling my cock out her throat, gagging on it. “Don’t worry, I’m just gonna sh-wear long jeans this summer. She-sh won’t notish”
A greenish liquid leaked out of her lips and dripped on my balls.
She gasped for air and puked on the floor.
“Sis, are you okay? Take a deep breath”
“I’m sorry master. This is all my fault. Please, step on my head while I clean the mess I made”
She licked the stain of vomit off the floor.
“Fuck that! You are still not finished! You can’t leave me like this”
“But we can’t leave all this filth here! I’ll get something to clean. Don’t get soft while you wait” and off she went.
Yeah, as if I could ever get soft without cumming after what she did to me. I stroked my cock slowly, waiting for her return.
She came back with the vacuum cleaner, riding the extension rod. As she turned it on, the vacuum cleaner created an updraft which lifted her skirt. She wasn’t wearing panties. This wind dried up the droplets of pussy juice that were leaking from her cunt.
Stacy moved the vacuum back and forth by holding the extension rod between her thighs and shaking her waist. The chickpeas were sucked in.
“Who’s got the bigger dick now, bro?” she said grinding her cunt on the rod.
“That’s not a real dick, Stacy. Come ride mine instead.”
She lifted the hollow rod and pushed its end against my cock. The vacuum made a screeching sound. My dick couldn’t fit in that tiny hole.
“Well, it looks like yours is larger than mine at least”
“It’s still long enough to touch your womb, sis. Wanna try it?”
“Maybe later. I’m good for now.”
The suction on my cock increased as Stacy pushed the button to increase the vacuum’s power. I moaned loudly. The rod ran along my shaft all the way to my balls, while Stacy turned on and off the power.
Then, I screamed in agony.
My testicles were sucked in, and for a moment I thought that blasted appliance would have ripped them off.
Stacy turned off the power and pulled the plug.
“I’m sorry. Are you alright?”
“Yeah, I guess”
“Do you wanna keep going?”
“Oh yes, but not like this. Now I have a surprise for you, Stacy”
I brought her to my room, grabbing her by the wrist, and threw her onto my bed. I searched my closet for a pair of trousers and grabbed the hanger used to hold them.
“You know what we’re gonna use this for, don’t you?” She shook her head.
Her mouth said “No”, but her eyes screamed “Yes” and “Fuck me”
I went on top of her and took the measurements.
“Yes, this is perfect”
The hanger was just long enough for the little pliers on each end of it to pinch both her nipples at the same time. The first plier pinched her nipple through the fabric of her shirt. The nipple became hard and my sister moaned loudly. She attached the second plier to her other nipple by herself.
“I’ll be back in a couple of minutes. In the meantime, enjoy yourself”
She replied with a moan and flipped me off. She pushed her middle finger inside her cunt. I went back to the kitchen, trying not to step on the pile of vomit.
I needed to take a break because I was about to cum. While I waited for my cock to cool down, I decided to mop the floor. Nothing was going to turn me off more than that work. While I was mopping the floor to clean the stain of vomit, I noticed a gas lighter near the stove.
That gave me an idea. I would have finished that job later.
I pulled my pants up, put the gas lighter inside of them and went back to my room. My sister had removed her shirt and bra and was fingering herself. The pliers were now pinching her nipples directly.
“Kept you waiting, uh? Look who’s happy to see you” I said jiggling my bulge, which looked twice as big as before.
I whipped it out along with the lighter. Her pupils widened as she saw her new toy. I hopped on the bed. My hands reached for her belly and I tickled her on the stomach. She burst into laughter immediately.
She looked defenseless while moving so erratically. I took advantage of it, placing the gas lighter on the metal bar that joined the two little pliers. I pressed the button and a small spark of electricity traveled at the speed of light through the trouser hanger to her nipples. My sister had a spasm of pleasure.
I didn’t stop there. I shocked her again. On the nipples, on her ears, on her toes, on her ass. She was shaking in convulsions.
“And now for the main event” I took off my underpants and stuffed them inside her mouth. She licked the dampness off them.
Her pussy was dripping juices down to her ankles. I placed the gas lighter on her clit. She gasped and sunk her teeth into my underwear, preparing for the shock.
The spark traveled on her legs, following the river of pussy juice. She gasped. Her legs were shaking. Her pussy looked like a collapsing dam, squirting everywhere on my bedsheets.
Turns out her nectar was an excellent conductor of electricity. So, I pushed the gas lighter inside her pussy.
“Wait! What about you? I want to feel you inside me”
She had a point. “I guess I’ll just stick it in your ass then”
“That’s a good idea. I have something that may help you do it” My sister stood up and searched her purse.
“Remember these? We used to play with these all the time last summer”
In her hand were about a dozen large colored marbles made of metal. The same ones she was playing with a few days ago. They were still covered in sand.
“Yeah, I do. We just found better ways to entertain ourselves”
“What if I told you we can still have fun with these? Don’t worry, I don’t wanna build a track in the sand”
One by one, she pushed the marbles inside her tiny asshole.
“My bowel is the track now. Let’s see how far you can push them with your dick”
I pushed my cock inside her anus. The tip of my dick hit the cold steel of the marbles, which rolled up inside her as I entered. My cock was like a tank engine pushing wagons on a railway.
My sister clenched her butthole and pushed the marbles down with a bowel movement. I pushed my cock harder inside her. I didn’t wanna lose this fight. The marbles rolled back and forth her intestine. I thrusted my dick inside her even harder. She tightened her ass even more. My dick was stuck inside her with no way to proceed.
I grabbed the gas lighter and pushed the button. The shock travelled from inside her pussy to the steel marbles in her ass and back to my cock and balls. Her asshole loosened and I got back to pounding her. My sister put her arms around me and dug her nails in my back.
We were both very close. Last time I came first but I wasn’t gonna lose to my sister again. I knew I could make her cum by just constantly shocking her pussy. It was much more intense for her. But that would had been too easy.
I removed the pliers from her tits and sucked on them instead. Her stiff nipples softened under the blows of my tongue.
And then, the doorbell rang.
“Fuck! Mom is back already? How long have we been fucking?” Shit! The kitchen floor! If mom sees that mess, she is gonna kill us!”
“Don’t worry about that. Shit out those marbles, quick! I’ll stop her!”
I grabbed my pants, rushed to the entrance, and locked the door. Just in time to see the handle being pulled.
“Julian, Stacy! It’s me. I’m back! Open up!”
“Hey mom. Wait outside a couple of minutes. We got roaches in here”
“What, roaches? Where?”
“I dunno. I’m trying to find it. Only Stacy saw it. It crawled on her leg and she puked all over the place. Hopefully, it’s still in the kitchen. I’m gonna hit it with the mop when I see it.”
“Hurry up and let me in!” She yelled.
I couldn’t refuse. Hopefully, I had bought Stacy enough time to shit out all the marbles. I put my cock back in my pants.
I turned the key inside the lock and opened up. My mother’s face was livid purple. Her eyeliner had been smeared all over her cheeks by a river of tears. Her ponytail was uncombed, and her lips were pale white. My dick went soft at the mere sight of her.
“What happened?” I asked.
“Where’s Stacy? Is she okay?”
“She is in my room now”. I said.
Mom pushed me aside and rushed to my room, passing through the kitchen, and stepped on the pile of vomit in her high heels, leaving footprints all over, only to find the door locked.
She knocked on the door.
“Stacy, are you alright?”
“Is it gone now?” my sister replied.
“I don’t know where it is, but I’m here now. It’s going to be alright”
Stacy stood up and opened the door. While I was stalling for time, she had changed her clothes. She was wearing a pair of tight jeans to hide the scratches on her knees. Her movement looked stiff, and her butt was sticking out. Mom hugged her tightly with her arms around her neck. My sister’s face rested on her breasts.
“Mom, what’s wrong with your face?”
“It’s gonna be alright. I’ll mop the floor on the kitchen, and I’ll find that disgusting insect”.
While my mother was busy doing that job, my sister pulled the last few marbles out of her ass with her fingers. When mom finished cleaning up, she went straight to the shower, and my sister and I had some time to talk.
