"Yo, what's up with your sister lately?" Tom asked, well out of earshot of Maya.
"What do you mean?" I asked cautiously.
Did he know what we were doing? Had he found out somehow? Even though we were just warming up, I felt a drop of sweat roll down my back.
"She seems different, somehow. Happier. She's smiling a lot more and the two of you haven't torn out each others' throats in a while."
"Oh," I said, relaxing. "No, I don't think so."
"I figured you would be the one to know. That reminds me, do you know if she has a boyfriend? Or a girlfriend?"
"I was thinking of maybe asking her out for a coffee sometime."
"I see," I said, resisting the urge to punch him in the face. "No."
"She doesn't have a boyfriend."
"You think she'd go for me?"
Fortunately, I didn't have to answer that question as Maya chose that time to loudly yell across the track.
That was, of course, me. I looked at her waving her arms for my attention.
"What?" I called back.
"Catch me if you can!" she shouted.
Before the words even registered in my brain, she turned around and started running. My muscles kicked in and I quickly ran after her.
We were supposed to run a five-mile course today, through actual fields instead of the rubber track. Behind the football field was a small thicket of trees and a cornfield behind that. Plenty of easy-on-your-feet dirt tracks that were well worn over the years.
At a moderate pace, it would have taken us anywhere from thirty to forty-five minutes, depending on how hard we wanted to push ourselves. Maya was sprinting at top speed.
"Hey! Slow down you two!" Coach yelled after us.
Neither of us listened. By the time I crossed the football field, my legs were already burning but I gained some distance on Maya. I was close enough to see all the muscles in her legs and, more importantly, her butt. That perfectly shaped, firm ass. Fortunately, running kept me from having an erection.
The problem was Maya was damn fast. Faster than me unless it was a particularly good day. Today had to be a particularly good day or at least I willed it to be. Even though running on grass was a lot easier, each footfall still jarred my body.
Nevertheless, I pressed on, ignoring the burning muscles in my thigh.
When we reached the entrance of the thicket, Maya risked looking around to see how close I was. Her smile reached from ear to ear and her eyes were sparkling with delight. She was sweating as much as I was.
"Hurry up, loser!" she shouted.
That was her mistake. I didn't reply, I only kept running. We were halfway through the thicket when I was close enough to touch her. Fifty more feet and I caught ahold of her wrist. Suddenly off-balance, Maya stumbled.
We careened off the path, between two big tree trunks, half stumbling, half running with little control. My foot caught on a root and suddenly I tasted dirt. Maya yelped and went down with me.
When we finally came to a halt, both of us were laughing with excitement. My foot, thigh, and elbow hurt but I had something more important on my mind. I shoved my hand underneath Maya's t-shirt and under her sports bra and squeezed her right breast. She let out a happy gasp.
With my free hand, I pushed down my shorts while she was removing her own. My sister's pussy was perfect, even covered in a sheen of sweat and dirt. I grabbed her thigh and positioned myself between her legs.
It didn't matter how many times I've done it now, it still felt amazing to enter her. She wrapped her legs around me and we fucked on the forest ground with animalistic passion. Powerful, raw sex that left both of us breathless after we came.
After my first and her second climax, I rolled off of her and we laid next to each other, recovering our breath.
"I'm still waiting," Maya said.
That's what she always said after we fucked. Ever since the day of kitchen sex and she told me she expected me to "try harder." She was waiting and the problem was, I didn't have any good ideas.
What was more extreme than fucking her in the ass in the presence of our mother? Everything else seemed to pale in comparison to that.
A group of runners passed roughly fifty feet away. I looked up but there was a tree with large roots between us and the road. Nobody could see us.
"What would you do if someone caught us?" Maya asked quietly.
"I don't know. Probably die of shame."
"You're embarrassed of me that much?" Maya pouted.
"No, that's not what I meant, I simply—"
"Relax," Maya giggled. "I know what you mean. Our lives would be done for."
"Yeah," I sighed.
"But that's what makes it so much hotter, right?"
"I don't know. I could go for a nice romantic bath with nobody around for miles."
"Boooring! If I knew how much of a prude you are I never would have let you tap this."
"Let you?" I asked, annoyed. "Remember, I was the one that fucked you on that bus."
"Ugh, that was so much hard work," Maya groaned. "It took me weeks and weeks of getting you angry enough to work up the courage. I literally had to tell you to feel me up before you even got the idea."
"I had no idea."
Thinking bad on the last couple of weeks, it definitely seemed like we had been fighting more. She had been thinking about me that way the entire time. I wish I had known so she didn't have to suffer in quiet.
"That's because you're an idiot. And you're unimaginative. I'm still waiting."
"I guess I should spill the surprise, then," I said.
"Oh?" Maya asked, perking up.
"I was going to wait until you missed your next period but last week I replaced your pill with fakes."
"WHAT?" Maya shouted and instantly sat up.
With wide eyes and a slack jaw, she stared at me. I tried to keep my composure but seeing the ridiculous look on her, I couldn't help but crack a smile.
"You asshole!" she growled and slapped my shoulder.
"You should have seen the look on your face!" I laughed.
"Oh, God, I think my heart stopped for a second," Maya said, lying back down.
"Looks like I finally flapped you."
"That one doesn't count."
"Because it wasn't at all filthy."
"You said you are unflappable, not you are unflappable-but-only-in-perverted-scenarios."
"It was implied, dumbass."
"Are there any limits to what I should come up with?"
"None as long as nobody finds out we're fucking."
"None at all."
"What if I want to poop on you?"
"Then we wouldn't be doing this in the first place. I know you pretty well, baby brother, and I trust your judgment."
"Oooh, what's this?" Maya squealed with delight.
In front of her, on her own bed, laid an assortment of instruments. A blindfold, sexy lingerie, two sets of handcuffs, a nylon rope, nipple clamps, and a butt plug.
"I hope you're okay with being humiliated, slut," I said in a commanding voice.
"I definitely am but I'm afraid this is all pretty vanilla stuff," she fired back, pulling her t-shirt over her head.
"How often have you used handcuffs during sex before?" I asked in a less commanding voice.
"Well, technically never, I suppose, but it's still pretty vanilla."
"Uh-huh. We'll see how you feel about that later."
Bare-chested, Maya picked up the nipple clamps and attached them to her nipples. A thin, silver chain connected them, and she tugged on it, stretching her nipples.
"I like this."
While she was distracted playing with her nipples, I pulled down her yoga pants and planted a kiss on her buttcheek. She retorted by slamming her butt in my face, knocking me on my ass.
"Don't kiss my butt, that's weird," Maya said.
"So fucking you in the ass is okay but kissing it is not?"
"That's right. Now get on with the kinky stuff, I'm horny."
"As the lady commands," I said, scrambling to my feet. "But first things first, show me how to unlock your phone."
"Why?" Maya asked suspiciously.
"So we can make some memories, of course."
"Why not use your own phone?"
"Does the thought of me accessing your phone make you... flapped?" I suggested.
"No, not at all," Maya said stubbornly, jutting out her chin. "Fine. Give it to me."
I grabbed the phone on her desk and she put in the code. A circle, counter-clockwise, starting with the top right corner.
"Thank you. Now it's time for the blindfold."
Once she was blindfolded, the process was quite a bit easier. I led her by the chain to the bed and had her lie down. True to her words, she was incredibly horny. The opening of her vagina glistened with grool. I probed with a finger and licked it clean.
Obediently, Maya raised both of her arms, pressing her wrists together. I grabbed both sets of handcuffs but instead of locking up her wrists, I cuffed each hand with its own set. After hearing the second cuff snap shut, she tested her new restraints.
"What's going on?" she asked, gesticulating wildly with her arms. "Why am I not locked up?"
"Feet up, my dear sister," I said, hoping she could hear the grin in my words.
"Ooh," Maya squealed and raised her knees to her chest.
I cuffed her left arm to her left ankle and her right arm to the right ankle. She was still able to move her limbs somewhat freely, save for not being able to put her legs down anymore. A rivulet of grool flowed out of her vagina.
"Now it's time for the rope," I announced.
"Yes, please. Tie me up and use me like a sex toy."
The rope was meant for climbing and had a strength well in excess of anything Maya would be capable of. I climbed up on the bed and looped one end around the back bedpost. With two strands in hand, I wrapped one end several times around her ankle, underneath the cuff, and tugged on the other end until Maya toppled over to the side.
"Does that hurt?" I asked.
"No, you should make it tighter."
That was good enough. I wound the other end until Maya's wrist a few times, securing both limbs. With a few feet of slack, I repeated the same on the other side. Now came the fun part. I pulled on the two strands, forcing my sister to spread her legs.
Being pretty athletic, Maya managed an almost perfect hundred-eighty-degrees.
"Does that hurt?" I asked.
"It's a little uncomfortable but not painful."
"How long do you think you could stay like that?"
"Much longer than it takes you to cum, that's for sure," Maya laughed.
"You're gonna pay for that."
"I hope so!"
I secured the two ends around the bedpost and double-checked to make sure the rope was taut but still had a little bit of wiggle room. Enough for her to squirm but not enough to escape.
The sight was glorious. Maya's pussy was spread wide open, labia parted, plenty of pink visible. I knelt down in front of the bed and licked across her opening, lapping up the wonderful juices.
"Eww," Maya squealed, trying to squirm away.
Up until today, we had pretty much just fucked. Pussy and ass but not much else. No foreplay, no kissing, no blowjobs, and no eating out. That was about to change.
"Does my tongue rattle you?" I asked.
"Of course not!"
"I'll stop if you admit you're flapped."
"Munch away, loser."
And munch I did. I wasn't the best at giving oral but Maya was easy to please, especially in her state of arousal. I ate her out until she began trembling, moaning, and fighting the restraints.
If she couldn't escape her chains while climaxing, they were good to go.
"Ow," Maya whined after the tremors stopped. "Cumming hurts like this."
"Good thing that was the last one, then," I chuckled.
"What?" Maya asked, raising her head despite the blindfold.
Ignoring her, I grabbed the buttplug and dipped it into her pussy to get it all coated up with lubricant. It was thinner than my penis and I had no problems pushing it into her sphincter. The base of it had a sticker on it, pink with black writing, reading "Daddy's Girl". Was that too much?
Would it all be too much?
"You want to be humiliated, right?" I asked, doubting my plan.
"Yes," Maya growled. "Please do your absolute worst. I want to be humiliated. I want to be punished. I want to feel like a whore."
I unzipped my pants.
The bed was a little too low for it to be very comfortable. I braced myself on the mattress and climbed on top of her, thrusting into her slowly. Maya let out a moan of satisfaction and she melted into the bed.
Instead of doing what I wanted, I pulled out and began jerking off.
"Hey, don't stop now!" Maya complained.
Fortunately, I had plenty of visual stimulation in addition to the fresh memory of my sister's pussy and I was ready fairly quickly. The first rope of cum launched through the air, splattering on Maya's naked body, reaching from her collarbone to her belly button. The second rope landed on her abdomen. The third right on her mound.
Quickly dipping just the tip back into her pussy, I continued stroking until the rest of cum was inside of her. I pulled out and the desired effect came at once. A white glob of cum appeared at her entrance.
"That was the worst sex I've ever had," Maya said.
"It's gonna feel like heaven compared to what's gonna happen next."
"Why? What are you planning on doing?"
"You'll find out in about... twenty-five minutes, I'd say."
"Why twenty-five minutes?"
I grabbed Maya's phone and took a picture of her lying there. Scrolling through the contact list, I found the entry for "Dad". I typed a quick message: "dad can u come home please? i need help. urgent"
My heart hammered and doubt rose up in me again but I ignored it and hit send.
"I'm sorry," I said in advance.
"Sorry for what?" Maya asked.
I reached into my pocket and pulled out Maya's favorite lipstick. I uncapped it and wrote two words, one on her left thigh, one on her right: CHEATING WHORE.
"What did you write on me?" Maya begged.
"It's a surprise. I really hope you like it because if you don't, this is going to really suck. For both of us."
"Why? What did you do?"
"I'll talk to you later," I said and headed for the door.
"Danny! What did you do?" Maya shouted.
I opened the door and took one last look at her. Tied up with semen dripping out of her beautiful pussy. Nipple clamps and blindfold.
Praying that I was doing the right thing, I left the room and closed the door.
"DANNY!" came Maya's muffled shout.
Around seven, I returned from my run. My knees hurt and my clothes were drenched in sweat. All my muscles ached, worst of all my stomach.
The longer I waited, the worse I felt. I had to face the music at some point. Either Maya would forgive me or she wouldn't but there was no turning back the clock.
Coming up on our house, I was on the lookout for anything out of the ordinary. Mom's and Dad's cars were in the driveway and there were no cops or EMTs. That was a good sign. The light in the living room was on.
Even though I was exhausted, I wanted to turn around and run another mile. I took a deep breath and entered.
The moment I stepped foot in the house, Mom scurried through the hallway and intercepted me. My stomach dropped in anticipation.
"You're back," she said, voice filled with anxiety as if she hadn't seen me in years.
"I was just out for a run," I said.
"Listen, Danny, Daniel, I know that you and your sister don't get along most of the time but I want you to promise me that you won't do anything to get in a fight today, okay?"
Did something happen? Did she try to escape and somehow injure herself? My stomach twisted into a knot.
"Why? What happened?"
"Please promise me. For me."
"Okay. I promise," I said quickly.
"Your sister has had a..." Mom said and took a deep breath, "rough breakup."
Relief washed over me. She wasn't in the hospital or worse. A rough breakup indeed.
"Oh?" I asked, curiosity piqued.
"She's totally fine," Mom assured me, not managing to sound convincing, "but she's quite heartbroken. So be nice to your sister, okay?"
"Sure," I said, stepping past her and heading to the kitchen.
There she sat, opposite Dad, with an empty carton of ice cream in front of her. There were three shot glasses and Dad's good bottle of whisky. Maya wore a thick sweater and her hair was wet but otherwise, she looked healthy. Until she saw me and her eyes turned into two sharp daggers.
"I'm gonna go take a shower," I announced and headed upstairs.
Yep, I was going to pay for that one but Maya hadn't told them anything.
It was a little past midnight when the door to my room opened and a slender figure slipped inside. I was already in bed but haven't been able to so much as close my eyes. I was way too wired.
Sitting up, I flicked on the lamp on the night table. Maya stood in the middle of the room, also wearing pajamas, lips snarling, fists balled. No knives or other weapons except for her raw fury.
"You!" she hissed quietly.
"I'm so sorry. It was the only thing I could think of."
Maya just stood there, breathing heavily. I wasn't sure if she was contemplating attacking me or running away. She advanced on me until she stood next to the bed.
For a split second, my vision went dark, followed by a spike of pain emanating from my cheek. Maya had slapped me, hard. Before I had a chance to react, I felt something much nicer than her fingers.
Soft lips touched mine and she kissed me with an energy I've never felt before. It wasn't so much a kiss as her trying to suffocate me with her lips. She climbed on top of me, sitting on my stomach, so she could devour me.
We only stopped because we ran out of breath.
"You... asshole," she said, gasping. "You stupid... fucking... asshole."
"How did it go?" I asked.
"What the fuck do you think? It was mortifying!"
"Sorry," I muttered.
Maya jumped off me and lifted the blanket. She pushed down her pajama pants and slipped under the covers, straddling me for real. Five seconds later, my cock was inside her pussy. She didn't ride me so much as she just thrust herself backward on my cock with a ferocity that was hard to believe.
In record time, Maya succumbed to her orgasm. Her entire body vibrated and she closed her eyes, letting out a few soft moans. Afterward, she collapsed on top of me with my hard cock still lodged inside her.
"I've been waiting to do that all evening," she sighed.
"So you're not.. angry?"
"Of course I'm angry!" she purred like a kitten.
"Were you, uh, flapped?"
Maya raised her upper body and looked at me, smiling mischievously.
"Of course not, baby brother. I was as cool as a cucumber the entire time."
"Really? I was worried the entire time. How did it go?"
"Pretty much as you would expect. Dad walked in on me, spread eagle, bound to the bed. He sounded like he had a small heart attack and refused to come in the room."
"So how'd you get free?"
"He called Mom for help."
"Yeah. I laid there for another twenty minutes, waiting for Mom to get home with Dad standing around the corner, apologizing every ten seconds."
"That sounds like Dad."
"Anyway, Mom made much less of a fuss but she couldn't get the knots to open. She practically forced Dad to help her. They managed to untie me in the end."
"Mom told me to be nice to you because you had a rough breakup."
"Yeah, I had to tell them something, didn't I? Dad was threatening to call the cops and have them arrest whoever did this, so I told them I had been dating this asshole and this was his way of dumping me and I just wanted to get over it."
"That guy sounds like a big jerk."
"Yeah, a stupid, dumb, idiot, cute jerk," she said.
With that, she began moving again, slowly grinding on my cock. I grabbed her butt and squeezed it. My fingertips bumped into something hard. I felt around and noticed the buttplug for the first time.
