**Chapter 15**
“Ava.” I settled back under the covers, scooting close to my little sister’s naked body.
Sharing a bed with a woman was still an unfamiliar experience. And the fact that I was cuddled up with my own sister, the girl I was secretly in love with ever since forever… it was nerve wracking.
Blowing out a breath, I slung an arm around her, molding her curves into me, sighing as her warmth returned.
God, she smelled so fucking good.
“Ava,” I repeated, trailing a finger along the leather of her collar and drawing my other hand down her back, fully enjoying the smooth, curvy trip.
“Mhm?” My sister half opened her eyes, recognized me, then shut her blues and cuddled closer, tickling my nose with a few locks of her pink hair.
It was tempting to stay in this position forever, with her legs tangled over mine, our lips inches apart, my boner pressed against her stomach, her amazing scent filling me up.
Men would kill to be in my position, to have someone so young and flawless like Ava completely enthralled to them.
As long as I gave my sister my love, she would allow me to do whatever I wanted. Dress her up in innocent uniforms or slutty ones. Fuck her anywhere, in any position. Anytime. However long I wanted in any intensity I desired.
Yet here I was, content, but still craving for *more*.
Greedy? Definitely. But it was the same greed that gave me the push to stop being a bitch. Being wrapped around Ava’s finger was a fate many men would love to be tangled under, just to have a sampling of her divine lips, to have a chance of feeling what it was like to be buried inside her exquisite pussy.
But it wasn’t the fate I wanted.
I always knew it should be the other way around. She was my bratty little sister, and I was the man of the house with two women living in it.
They were… fuck… my sisters were perfect, and I had suffered long enough being in love with both of them, seeing them every single day, wishing I wasn’t their loser brother.
But the dynamic finally changed. Ava was a massive help in morphing me into a man, buying me better fitting clothes, giving me a total makeover, pushing me to the gym, teaching me how to properly make love to a woman. To her.
I may have dominated the younger, sexier sister, but why be content with one when I could own both?
The erotic image floated to the front of my thoughts.
Lucia on her knees, a collar wrapped around her neck, calling me Master…
Fuck.
“Hey,” I said, stifling a groan when Ava nudged closer until there wasn’t a pocket of air left between our naked bodies. Her lips were pressed against mine, and as I spoke, I could taste sips of vanilla. “Ava.”
She kept her eyes shut. “Hmm?”
My cock twitched at the sound of her voice. She smiled and let out a sleepy giggle, nuzzling her forehead against mine.
Yeap, if my feelings weren’t enough confirmation already, I was utterly and desperately in love with my little sister, drowned deep in an ocean of lust for the eighteen-year-old cuddling with me, smelling like an angel.
“Wake up, baby.” I wanted to get up, but her legs were draped over mine, and her pussy was touching my upper thigh. I could feel the first leak of wetness dripping out of her.
“What time is it?”
“Nine.”
Finally, she opened her eyes. “Morning or evening?”
I rubbed my palm against her bare ass, waiting for her to…
There it was. The shudder.
“Evening,” I told her, skating my palm closer to her pussy. She was so used to it by now that she didn’t even react, just stayed still, waiting for me to feel her up. “If it’s morning, we would be late for classes.”
“Fuck school.” She sighed, squeezing her eyes back shut. “Stay with me.”
“I’m here.” I found her clit and gave her a few rubs with my thumb, causing my sister to leak out a soft—very soft—moan. “I won’t leave you.”
I was staring at her blues again.
“Do you want to fuck?” she asked me, her tone raspy, her breathing growing louder by the second. I felt Ava’s hands maneuver under the blanket, and the next thing I knew, she was holding my erection. “You never do get soft, do you?”
“No,” I growled. Fuck. I would much rather have her touch me, so I dropped my hand, relaxing as she drew the pad of her thumb over my slit, rubbing slow circles.
“So…” She gave me a couple of nice, slow pumps. “Are we fucking? Does Master want to stretch his little sister open?”
Ava and her filthy mouth. Mom and dad would go deaf at hearing those words.
“I have other plans.” I managed the willpower to sit up and peel away from her addictive touches, but the damage had been done. I was throbbing so much and the first pearls of pre-cum beaded out of my tip.
“Hmm?” My sister sat up, resting against the headboard and rubbing the sleep away from her beautiful blue eyes. “What are you going to do to me?”
Instead of answering, I stalked out of bed and headed towards the black plastic bag filled with goodies we had purchased this morning. Was it this morning? It felt like ages ago.
I palmed the toy I wanted and returned to bed.
“Is it the anal beads?” Ava guessed, squinting at my fist as I scooted in front of her. Automatically, she opened her legs for me. “I’m still a little sore there, but maybe…” She shrugged, twirling a lock of pink hair around her finger. “I don’t know. We could try, I guess.”
Anal sex was another view I was determined to change my sister’s opinions on.
By the time her ‘training’ was complete, her default position would be on all fours, hips up, cheeks spread open, and she would be begging me to rip her tight channel apart.
And by ‘training,’ I meant fucking her ass every day until she was used to it. After all, my sister had a high pain tolerance.
I smiled at the thought. Ava was wrong about the toy I was holding. I was beyond excited to have her impossibly tight hole clench around my cock once more, but I understood that she was still in pain and needed to recover. I would give her the night’s rest, but once tomorrow came, the time for small mercies were over.
Opening my palm, I showed her the pink bullet vibrator and the remote control sitting beside it.
My sister giggled and took the vibrator from my hand, studying it closely.
“I love these types of toys,” she told me, her voice slowly dipping back to her normal tone, all feminine and seductive. “But I never used a remote controlled one.”
I arched a brow. “Do you use toys a lot?”
“Mmm hmm.” She sighed and grabbed my cock again, offering slow, skillful strokes. “I probably masturbate like…”
She paused to think, but her concentration didn’t waver. Instead, her pumps grew faster. “I don’t know, maybe five to eight times a day when I get reallyyyyy horny. I couldn’t find a man to please me properly. You know… get my buttons going.” She shot me a dazzling smile and fluttered her eyelids. “Until I discovered this huge, yummy cock.”
“You’re a sex fiend, little sis,” I said, before dipping forward and claiming her lips. Ava moaned at the contact, the delicious pumps on my cock halting, completely fixated on the kiss, parting her lips to invite me in.
Ava clutched my biceps as I sparred with her tongue. She was eager to deepen the kiss, her nails digging into my skin, her lips trembling, a silent plea for me to bring the intensity up, but I was done with her lips, my thoughts already on her pussy, and what I was going to do with it.
“Hey,” my sister whined when I drew back. “That was a quick kiss.”
I thread my fingers into her wealth of pink hair. “And?”
“There’s a thing called foreplay, remember? To get me wet and ready before sex.”
I glanced down at her pussy, which was glistening under the bright bedroom lights. Ava followed my stare, then shot me a frown when I smiled at her.
“I think you’re wet enough, little sis.” I moved away and sat up against the headrest. “And besides, I’m not going to fuck you just yet.”
She sank her teeth into her bottom lip, her blue eyes flickering to the bullet toy. “What are you going to do to me?”
“Come here.” I opened my legs and patted the spot in between them.
No hesitation. My sister obeyed, settling on the spot, pressing her ass against my erection.
I groaned and tucked her hair behind her ear. I felt bad about not kissing her the way she wanted me to, so I planted a peck on the side of her neck, which got her humming happily. Ava got herself comfortable, spreading her legs wide.
She knew what I was going to do to her, and judging by her heavy breaths, she was more excited about it than I was.
“Good girl,” I rasped, turning on the vibrator. I started with the lowest setting. Level one.
*Bzzzzzz*
Ava grew silent, and I enjoyed every shaky inhale and exhale she released.
I slid the vibrator along her inner thighs, chuckling when my sister yelped, but my amusement quickly fazed out when she jerked up against me, slipping my erection into the seam of her ass.
“Ava.” I gritted my teeth, my ears ringing, my heart a battering ram. “Fuck.”
She squealed. “Oh my god, Aaron.” Giggling, she continued. “This…. this is so wrong.”
“Wrong?” I inched the vibrating toy closer to her pussy and was rewarded by another girly squeal. “Ava, we have already done the worst of the worst. I have gagged you, bound you, collared you, fuck you in every important hole. Countless times. What’s dirty about this?”
“I don’t know…” She hiccuped, then tensed as I brought the toy along the outskirts of her swollen folds. “The toys. The toys make everything so much dirtier. I love it. I—AH!”
I could tell she was already close to the edge, and we had just begun.
“Are you going to squirt all over my hand, Ava?” I asked, staring down at her pussy. “Are you going to make a big mess on the bed again?”
She was gasping and arching high, so I had a perfect vantage point from behind her shoulder, and my god, she was dripping wet, practically water falling her arousal.
I didn’t exactly expect a response. I was just teasing her because it was fun to see my sister so helpless and desperate.
Ava tried to say something, mumbling incoherent words between staggered breaths and excited gasps. When I leaned closer to try and understand her, she gave up, turned towards me and found my lips before I could say anything.
Fuck. Ava *really* loved kissing. I was a big fan of making out too, but Ava took it to a whole new level, letting out cute little whimpers, spilling out mewls, biting down on my lips as she darted her tongue forward to tangle with mine, sending me reeling with how fucking good she tasted.
I moaned from her sweetness, and pressed the button on the remote, turning up the vibrations to level two. A roar of heat rushed through my body, tempting out the animal inside me, drawing forth the frenetic drive that I always had for my beautiful little sister.
I didn’t even realize I had slid the bullet inside her until she screamed, her walls clamping down around my fingers, her nails digging into my arms like sharp daggers, her tongue tussling frantically with mine as I matched her sudden shift of intensity.
Oh fuck, fuck, fuck.
Holding her tight, I pressed down on the remote, and it beeped out a confirmation.
Level three.
*Beep.*
Level four.
*Beep.*
*Beep.*
“MHMMM!” Ava had forgone any and all technique. She was brutalizing my lips, our tongues licking and flicking in a lust filled frenzy. I struggled to keep up. “MHMMMMMMMM!”
How was she still hanging on? She should be squirting out fireworks by now, but somehow, my little sister refused to burst, showing me a level of restraint I never saw from her.
It was admirable, but I wanted to see the fireworks.
In the spur of the moment, in between all the craziness, I took out the toy, tossed it away and shoved my sister down. She yelped as her back hit the mattress, but I was on her before she could say anything, my lips reclaiming hers, tongues back on each other, cock primed above her pussy.
And then I thrust in.
Her tongue stilled. The kissing stopped.
The screams began.
“AARON!”
“FUCK!” I roared, squeezing my eyes just as tight as she was clenching around my cock, sparing me no space for movements, milking me for everything I was worth.
“AHHHHH!” Ava resumed kissing me, all rough bites and high-pitched cries. “AH—MASTER!”
There it was. The magical word.
*Master.*
“MASTER!” she shrieked again, her cries ear piercing, her sweat-slicked body writhing under me, trying to take me in deeper, but she was already clenching every single inch of me, dousing my thighs as she squirted out the fireworks I wanted. “OH MY FUCKING GOD!”
“Your pussy, little sis…” I was ramming into her with abandon, my thrusts as brutal as they could get, the sounds of my balls pounding against her flesh music to my ears. “Holy fuck, you feel so fucking good. So warm. So fucking tight.”
“YES!” Her wails had me cumming with her. “YES! YES! YES! YES!”
“Shit!” I tore away from her lips, unloading endless ropes into my sister, spilling out so much I felt my head lifting up to the heavens. Ava hadn’t stopped clamping around me, taking me to peaks of pleasure only she could provide.
I couldn’t stop fucking her. I didn’t want to, so I groaned in dismay as the last shot fizzled out, but for my sister, she had just started. Her orgasm seemed to renew. Over and over.
Her cries, screams, and moans filled the whole apartment up. I continued pumping into my sister because even though I was drained dry, pounding into her felt so fucking good.
I briefly wondered what our eldest sister was thinking. She *definitely* could hear Ava, especially with her room door opened ajar.
Would she… would she continue masturbating while hearing our little sister having the orgasm of her life, moaning her lungs out?
That was a nice thought, a crazy one, but what I was doing to Ava was even more insane.
Minutes melted away. I was with her every second, enjoying the sounds of her cute little screeches and the way she clawed at my back.
By the time she was finally done, we were dripping in sweat, our skin hot and slicked together, our chests heaving for air.
“Thank you,” Ava whispered the words so low, the only reason I could understand her was because I was hyper focused on her swollen lips, painted wet with our mixed saliva. “Thank you. Thank you. Thank you.”
I dipped low to offer my trembling sister a peck, but she raised a palm to touch my cheek, holding me in place, evolving the simple peck into a full-blown French kiss, our lips clashing, tongues tussling, moans colliding.
“I love you,” Ava croaked out when we mutually broke the kiss. Her blue eyes misted over, and her lips visibly trembled. “I love you so fucking much.”
“Ava…” I closed my eyes, relishing the tender moment, inhaling her heady scent and clutching her tight.
She pressed her lips against my cheek. “Let me thank you, Master. Let’s switch positions. How about anal? I can ride you with my ass. We haven’t tried that yet.”
I opened my eyes, and she sighed, her breaths hot on my skin.
“Please, Master?” She scraped her teeth along my jawline. “Let me show you how much I love you.”
“Ava,” I rasped, feeling like a dead weight on top of her, pins and needles prickling all over me. But my cock was still alive and hard, throbbing inside my little sister.
“Yes, Master?”
“Would you do anything for me?”
“Of course.” She pecked my cheeks.
“Anything?”
“Master.” She held my cheeks and made sure we were looking straight at each other. Jesus. Her blues were mesmerizing. “Just give me the order.”
The way she was gazing at me… the absolute devotion filling her eyes. Yeap. She would do absolutely anything I tell her to.
Gesturing my little sister to lean in, I outlined my plan.
When Ava slump back onto the mattress, her lips were a thin line, teasing a deep marred frown.
“Would you do it?” I asked her.
She nodded, but I caught the slight hesitation. “Of course.”
She was looking away, clearly unhappy about the situation, so I touched her cheek, drifting her gaze back to mine. “But you don’t like what I just told you?”
She shrugged, then started to pat down her pink hair. I rolled off her to give her space.
“I don’t have to enjoy everything you like,” she told me, peeking down at her pussy which was visibly pinkish and looked extremely tender. “All I can do is try my best to keep you happy. Because if you’re happy…”
She exhaled slowly and placed her hand over mine. “Then I’m happy.”
“Okay.” I nodded, and squeezed her hand. “Let’s pay our sister a visit.”
“Okay.”
