The K App - Opposite Day

All sexual activity is with characters 18 years of age or older.

Rodney choked on the toilet water, his head held in place once again by his tormentor. He longed for the flush, the sweet moment of reprieve from the oppressive, stinking water. Flush, damnit, flush! He couldn't breathe!

The young man sat up from his bed, covered in sweat and whooping air into his lungs. The nightmare again... Todd pushing him down into the toilet... while it hadn't happened in years, that asshole still threatened him every once in a while to keep his quarry on his toes.

And what Todd's girlfriend had done...

His phone chimed, the screen lighting up to indicate that it was just past midnight on April 1st. Happy April Fucking Fool's Day, he 'rejoiced'. Picking up the phone, he frowned at the new app on his home screen which was just a glowing red K. Curious, he tapped it.

"Oh... oh wow..."

"Hey, Trinity!"

The fit ash blonde turned to see that dweeb Rodney approaching in the hallway with a smile on his face. The greasy-haired squib had been bullied by her boyfriend Todd all through high school, and she had even started a rumor a few months previous that the skinny loser had genital warts so that no girl would show any interest in him. "What do you want, deadend?"

"You hate me, right?"

She thought about it. "Well, I don't *hate* you, but I don't like you. Now why don't you fuck off before Todd sees you talking to me and folds you up like an envelope?"

The pale-faced guy thought for a moment. "You definitely wouldn't have sex with me, though?"

"WHAT!? Ew, no."

"Cool." He held his phone screen toward her. On it was a stylized K logo with a prominent, blinking message below: OPPOSITE DAY.

"Uh... shit."

"C'mon..." the slim guy grabbed her hand and pulled her up a nearby stairwell. Her head spun as he directed her into the wing of the school that was closed for renovations, pulled out a key, and opened a classroom. "I'm not supposed to have this key, but, y'know..." He tapped his phone and pulled her in with him. "Now, take off your clothes and bend over the desk."

She blushed as she pulled off her shirt, revealing her bra-covered C-cups, and then her thigh-high skirt. Normally, this skidmark wouldn't have a chance with a fit, popular, girl like her, but it was Opposite Day. She shrugged out of her titsling, pulled her lacy panties down, and assumed the position. "Hey, that kinda hurts," she winced as he started poking his dick at her dry vulva. "And you're not even using a condom! There's a lubricated one in my purse." She waited as he took the rubber out of its packet and smeared it all over his hard dick, but then he tossed it to the side.

She stared as he brought his bare, glistening six-incher toward her vulnerable pussy. "You can't... not without..."

He paused. "Do you ever do it without a condom?"

"No!"

"But it's Opposite Day." He pushed inside her.

"Oh-hh..." Rodney's member was six inches in length, a little longer than her boyfriend Todd's, though not as thick, so he was able to shove it all the way inside without much difficulty... then he started spewing.

"Ohhdaamnn..." he moaned as he inseminated her depths, the first man to do so.

"Goddamnit..." she groaned, disgusted.

He pulled out. "Phew! Normally I wouldn't be able to go again, but..." He activated his phone, the glow of the screen illuminating his plain face, and she could see his flagging dick rising again. "... y'know. Now, get up onto the desk, on your back with your legs over the side. That's it..." He stepped between her pale, shapely thighs and rubbed the head of his reinvigorated cock between her dripping pussy lips. "You hate this, right? I disgust you?"

"Yeah, you asshole!"

"But it's Opposite Day." He pushed back inside her.

It was like night and day: when he got his dick all the way inside, she came hard. "Ohhfuuck! Ugh! MMM! Rodney..."

"Yeah, that's it... cum on my cock, you fucking slut. You deserve this, you and Todd. Oh, look how hard your nipples are now... mmm..."

His head moved down and took one into his mouth, making her cum again. "Ngh! Ohh!"

The slim guy managed to fuck her for another ten minutes, giving her three more orgasms, before he started speeding up. He was going to cum inside her again, and this time she wanted it! She wrapped her arms and legs around him. "Yes... yes..."

"Urghhh!"

Feeling his hot load penetrate her unprotected depths once more, she came hard. "UNGHH! UHH! Huhh..."

Rodney pulled out a minute later, making her gasp at the sudden feeling of emptiness, other than the two loads of sperm-filled semen he'd deposited. "Now, I'm sure you want to tell people, especially your boyfriend, about this, but..." He held his phone screen out to her. "... now you won't, right?" She nodded as she tried to calm her body.

Sure enough, Trinity couldn't tell Todd or anyone else about what had happened, nor could she go to the washroom to drip out the dweeb's thick load after he mentioned it. Fucking Opposite Day! she raged. She spent the rest of the school day feeling his stuff trickle out into her panties. Her nipples remained hard, so she was glad for her bra.

After school, she and Todd went back to her house to do homework. However, as they entered through the front door, she heard her mother calling.

Stepping into her bedroom, Trinity gasped. Her 40-year-old blonde mother was naked on the bed, her plush ass in the air, and Rodney was there behind her, his hard cock ready to spear into her. "MOM!?"

"Holy fuck!" Todd yelled and ran forward. However, he stopped when Rodney pointed his phone screen at his long-time bully. "Opposite Day? Oh, no." The larger young man just stood there, impotent.

"Have a seat," Rodney gestured to the corners of the bed, and the newcomers did as directed. "You're really disturbed by this, right? Complete turn-off?" He held the screen out to them again.

Trinity gasped as her pussy thrummed at the sight of her curvy mother moving herself back, moaning as her pussy gobbled up the teen's cock. Out of the corner of her eye, she saw Todd rubbing his crotch as he watched the illicit sex with interest.

"Nice, huh?" Rodney moaned as he grinned at Trinity. "Your mom told me she's a lesbian and you were an IVF baby, so my cock's the first one that's ever gone inside her. This is so special."

"Ohh... ohhh..." Trinity's mom moaned as she pulled forward and pushed back onto Rodney's dick, her dangling D-cups swaying in time.

"I've informed her what a terrible mother she is," he told the younger woman while the other humped back at him. "She had no idea how you and Todd were fucking with me. Hmm... you would never masturbate while watching me fuck your mother, so why don't you do that now?"

With a groan, Trinity pulled off her skirt and shoved her fingers into her sopping panties while she watched.

Rodney let the older woman fuck back at him for several minutes before his face got that serene look. "You would definitely never cum at the same time that I impregnate your mother," he insisted, "and she would never cum at feeling that."

"Ohh... ohhh..." Trinity's mom moaned as she pushed back harder.

"Oh no..." Trinity moaned as she sluiced three fingers inside herself.

"Here... it... CUMS!" Todd closed his eyes and grunted.

Picturing his dangerous load spurting into her mother's unprotected depths, Trinity came hard. "OOHHH!" She felt a gush of liquid rush over her hand... she was spurting!

"OOOH!" Trinity's mom cried out and shook in orgasm, her eyes widening at the feeling of the first man ejaculating inside her. "Ohh... wooow..."

Everyone's orgasms calmed and Trinity lay back. Her mother fell forward, though she kept her butt in the air.

"Aah, that was amazing," Rodney said as he slipped off of the bed and picked up his clothes. "Now, let's make sure that I don't regret this later. Todd, you will definitely want to kill me after this, so in the spirit of Opposite Day, how about you swear that you'll think about me for every moment of the rest of your life?"

Todd looked stunned. "I... uh... I swear."

"And you two 'ladies'... swear that you'll tell everyone about what happened today, and that you'll definitely have abortions."

"We swear," both women said together.

Rodney held up his phone and the effect of Opposite Day took hold on his victims' minds, reversing everything they'd just sworn to. However, Trinity knew something Rodney didn't, and she was holding onto that for dear life.

Rodney looked over at her boyfriend. "Todd, I don't want to leave a bro hanging. You definitely wouldn't fuck Trinity's mother unprotected in front of her, so..." He gestured, and the larger young man undressed and got behind the older woman. Moments later, he was fucking her as well.

The slim young man leaned over Trinity. "I spent some time talking to your mother before you got here. You two have synced your periods, and it's a safe day today, huh?"

She stared at him, defiant.

"But, Trinity... it's Opposite Day."

She gasped as she felt a slight pinch in her side, and her mother moved a hand to her own midsection. Trinity knew that their ovaries had just released eggs... in her mind's eye, she could see that vulnerable little thing meandering down her fallopian tube, heading toward those two loads of dangerous sperm that Rodney had deposited inside her earlier that day. "No..."

"Gimme a kiss..."

She moaned as Rodney leaned down and they swapped spit. Behind them, they heard Todd grunt as he filled Trinity's mother's fertile depths with his own load of swimmers and the lesbian came again.

Rodney rummaged through Todd's pants to find his wallet. "Just grabbing your address, Todd. Hope your Mom's hot, and isn't your sister visiting from college? I love Opposite Day." Smiling, he headed out.

An hour later, leaving Todd's house behind along with two more thoroughly-inseminated women who were supposedly protected by birth control pills (but not today!), Rodney grinned as he walked home.

Spotting one of Trinity's cute friends as he crossed the street with the light, he pulled his phone out. After cumming so many times, there would be no way that he could get it up again, except... OPPOSITE DAY, the app agreed, and he felt his member reinvigorate.

"JEEZ!" The truck driver yelled as he rolled over the young man, the fool that had stupidly crossed with a walk signal on Opposite Day.

The K app will return...
