An Afterschool Secret

It was hard for them to keep their hands off each other after that first, hot encounter, but they really had to. The walls were thick but not entirely, completely soundproof, and Kuro was extremely vocal. So although they slept in the same room, they never really indulged their desires fully unless the house was completely empty, and it wasn't empty often at all, not with Liz and Sera being so lazy and dutiful. It didn't help that Illya's dick came into existence at odd times, triggered by excess mana or by her own dirty thoughts about Chloe. Which is to say it happened every day. A handjob or blowjob worked on most occasions, and Illya even managed to make it go away once on her own - much to Chloe's passive-aggressive ire, although Illya being Illya could not for the life of her understand why.
They could shower together but that was a disaster waiting to happen. Illya could not remember how many times their large household had stumbled in on each other, somehow. It was Not Safe.
So it was a surprisingly difficult life, but they made do, Illya deciding that her new endowment, eventual gratification, and close relationship with Chloe was worth the torture of a stiff erection.
As a bonus, the fact that they had to hold back made the times they could be together that much more hot.
"We'll have to figure out how this works." Chloe panted, jerking Illya off as her pale twin lapped and sucked at her cunt, the two of them locked in a sixty-nine. "G...gain some control over when you get it!"
Illya's long fingers were tight on the flesh of her twin's brown butt, grinding her twin's pussy into her face, lapping excitedly at the ongoing rush of juices. "Mmmmm..." she moaned distractedly, focusing on Chloe's soft smooth hands as she fondled her dick. She fixed her lips on Chloe's button and sucked on it, Chloe diving onto her dick in reaction, muffling a loud moan.
They were on the roof, in the shadow of the large, square structure that housed the entrance to the stairs. The lock was sealed, unlike the last time they were here, by a handy spell Chloe used. They'd brought a picnic blanket, not wanting to get their uniform sooty again, but it was quickly becoming scrunched up with their passionate motions, their slim bodies twisting and turning uncontrollably.
"We...just...can't keep doing it here...!" Chloe persisted. "S...someone will come...looking for us...M...Miyu or...hnnnghhhh!"
Illya took Chloe's clit between her teeth ever so gently, eager to show her that they had better things to do with their mouths than worry.
"Uughhh...jeez..." Chloe gasped, Illya hunching her hips up in need. "Wait..." She rose, crawling forward and off her, the tip of her stiffly erect cock grazing the smooth taut skin of her belly.
Illya propped herself up on her elbows to discern her twin's intentions, and swallowed, feeling her heartbeat speed up, her cock lurch.
"Hurry up." Chloe snapped, glaring backwards, a deep blush on her irritated face. She was on all fours, her butt wiggling into the air. Her cunt was dripping wet with her own juices and Illya's saliva. "Come on." She wiggled, gesturing.
"You want to do it...like that?"
"Y, yeah." Chloe snapped. "Hurry. It's not a big deal."
Illya uttered her assent, feeling dizzy. Not a big deal. This was how...animals do it.
On her knees, she moved towards her, taking her shaft in hand, easing it into her wet sister from behind, the head slipping past her lips. Chloe whimpered in response, her tight cunt stretching to accommodate her twin's stiff prick.
Her twin's plaintive cries giving her pause. "Does...does it hurt?" Illya whispered worriedly. They'd had penetrative sex twice since their first time - a shy fuck in the shower, and a week later, a scared, spontaneous, midnight tryst under the covers after an increasingly heated makeout session reached a peak on a Friday night. The both of them had muffled their cries of passion on each other's mouths.
"N...no." Chloe whispered. "It's just the angle...go...go gently...I...think it'll go...deep...aaaaaahhhh!!!"
Panting, she placed her hands on Chloe's curving hips, driving her cock deeper and deeper. "You...you're...n...naughty, Chlo..." Illya whispered, gazing down at her prone sister, her ass struggling to keep itself raised to her. "You...you look so...naughty....it's...so tight...."
Chlo panted, lowering her head. She felt so hot. "S...shut up! Quickly...do it...you...you're so...deep...inside...anyway...you might as well go...go all the way...!"
Illya obliged her, pulling her down the last bit of the way, pressing her groin and thighs to her sister's tight butt. They panted as Illya's cock bottomed out, her spongy blunt shaft reaching a significantly tighter part of her twin's vagina. She watching Chloe's beautiful back arch in a delightfully erotic way at the sensation.
"Ohh...oh god..." Chloe panted. "That's my..."
Illya panted, her vision tunneling, her senses narrowing as she felt truly joined to her twin. "Y...yeah...I...I think so...." Illya pulled out slowly, Chloe's wet, dripping cunt sucking her delightfully. She pressed in again, a short, shallow thrust, eyes glazing as she began building a rhythm, fucking her sister from behind, cockhead battering at the entrance to her sister's womb.
Chloe was moaning unabashedly, her fingers tight on the the blanket, clutching it as she felt Illya's cock slip in and out of her repeatedly. 'Ohhhh...this...this position...!' she sighed internally, feeling the full length of Illya's prick quickly reaching places it hadn't when they were fucking missionary. 'It's...so...' her vocabulary faltered as she tried to describe how 'right' it felt in addition to how good it felt. 'I...I...could really get addicted to this....' She felt one stab of Illya's cock strike something, and she tipped her head back in a loud shriek as a jolt of pleasure shot through her. "Eeeee!!!"
Illya stopped. "What...what's wrong?" she panted.
"N...nothing...I think...you..." she flushed. "There's a spot there...that's...supposed to be really sensitive...."
Illya was instantly, deeply interested in this fact. Chlo knew so much more than her about sex. "Hmmm...where...?" she crooned in askance, jabbing her cockhead to grind against the roof of Chloe's cunt. "Here...? So this spot here feels good?"
Chloe gasped with each thrust that hit the mark. "Y...Yes! Yes...yes...! Yes!"
Upon confirmation, Illya resumed fucking her twin, angling her cockhead, growing increasingly fascinated by her increasingly vocal pleasure.
"...Yes...unh...unh...unh...n...no...s..top...if you keep...doing that...I can't...I can't...!"
Her twin was on all fours, crying out in pleasure as Illya struck again and again, the nape of her neck just slightly visible through her long hair, much of it hanging over the sides of her face. "...Unhh...like...animals..." Illya breathed quietly, fucking her hardness heedlessly deep into her soft, squeezing cunt, staring down at Chloe's shaking body. There was something about the way Chloe was completely exposed to her that inspired feelings protective, cruel and arousing. Her gaze was drawn to Chloe's tight, clean, little rosebud. She sucked and drooled over her thumb, getting it slick.
"I...Illya!" Chloe cried, shocked, arching her spin in shock. "What...!"
"How about this? Does this feel good too?" Illya asked, using her wet thumb to rub her Chlo's little asshole, humping her hips into her with short, slow thrusts.
"Stop...stop touching that!!!"
"Hm? But the other day...I touched myself there...it felt good."
"What the heck...wait...wait! HnNNNNGHHH!" Chlo gasped, gritting her teeth as Illya teased her thumb into the soft, silky hole. "S..st...stoppp!" she cried out as Illya began fucking with increasing long, hard thrusts.
"Are you going to...*cum*...Chlo?" Illya panted, rolling the word Chloe taught her around as she speared her twin's body faster and faster. Chloe's asshole clutched at her thumb tightly. "I'm pretty close myself...."
"Hungh, hungh, hngghhhH!!!!" Chloe cried in time with Illya's thrusts. "HNGHH, HUNNNGHHH!" she wailed, cumming around Illya's cock.
Illya gasped in response to her fluttering, pulsing hole, racing to her own orgasm, driving Chloe onto her elbows with her thrusts, their faces twisted in identical expressions of helpless pleasure. "Ohhhhh...C...Chlo...t...tight...! Unh, hunh, unhunh...c...cumming...!" She drove her hips forward one final time, cock driving into her hot depths, erupting, blasting her twin's insides with her hot cum. "Unnnhhhh...unhhhh...." Illya grunted. She pulled her thumb from Chloe's asshole, using two hands to grind her twin's rear to her as she pumped load after load into her, deeper than ever before. Chloe's pussy milked her dry.
"You came so hard..." Illya gasped once she'd finished spurting, collapsing onto her twin's back. She kissed her on the temple. "It felt wonderful."
"...Chlo?"
"...Illya...you...you beast." Chlo whimpered, her cheek pressed to the picnic blanket.
Illya's jerked. "...I...sorry...I thought..." She felt her twin shuffle under her so she rose to allow Chloe to sit up. "I mean, it felt good, right?" Illya said placatingly, afraid Chlo was deeply upset.
Her twin lowered her eyes. "What if it becomes a habit?" she said, quietly, a thumbnail pressed to her pale lips in shy retrospection.
Illya's breath caught in her throat. "Uh...um..."
"If...if that happens, you'll...have to do something about that too," she said, pulling herself together, crossing her arms.
"O...of course." Illya snapped, crossing her own arms. "I...I said I'd take responsibility didn't I?" Chlo's discreetly shifting thighs caught her eye. "Um...it's...not gone. So...one more time...if...that's okay with you...?" She padded over.
Chloe uncrossed her arms. "Well. Of course. I told you right?" she blushed. "Any...anytime you want it."
Illya leaned over, delivering a long, slow kiss to the top of her twin's head, burying her nose in her scent. "We use the same shampoo, right?"
"...Yeah...."
"You smell so good though...."
Chloe's blush intensified. "Stop messing around and do it! We have to get home!" she snapped, but Illya was already pushing her down.

[On the way home]
Suzuka: "And so why do you think you need help, and why do you think I can help you?"
Mimi: "Well, I thought I was fine. But, s, sometimes, on the way home, I hear voices...in my head...and it sounds so real...."

Going to be short little pieces like this from now on. I want to explore a lot of different situations before the next 'real' chapter. Hope you enjoy watching them explore their relationship!
