[Part 1/2](https://www.reddit.com/r/incestsexstories/comments/w5f4ag/love_pill_part_8_12/)
Ava was true to her word. When I stepped out of her bathroom, she was perched on the edge of her bed, one hand jammed under her gray pleated skirt.
I wondered why I had even bothered wrapping a towel around my hips as I made my way towards my sister, feeling more refreshed after a nice steamy shower beneath pink lights
Ava withdrew her hand, using a finger to smear her juices on her lips as if it were lipstick. She looked up at me and puckered her lips. I didn’t hesitate to kiss her, tasting overwhelming sweetness.
I even braved the effort to journey up her smooth legs, slipping underneath her uniform, but Ava denied my efforts, giggling and slapping my hand away just as I found soaked panties.
“If I let you do that, we’d be here for hours.” She stood up and walked towards the door. “I need to eat. Replenish my energies after….” She glanced down at her feet before flicking her gaze back up to me, a smirk accompanying the look. “… last night. Aren’t you sore? Usually virgins would be sore, especially after what I did to you.”
My cock throbbed. I swallowed my groan.
“Just a little bit,” I lied.
“Mhmm.” She held her gaze for a few more seconds before gripping the doorknob. “Stay here. Let me make sure Lucy’s still asleep.”
With that, she was gone, appearing only a minute later, looking absolutely fuckable in her school uniform. After last night, it was impossible to look at Ava and not think about burying myself into her tight pussy and rubbing up against all her flexible curves.
“She’s asleep,” my little sister confirmed. “Come out, get changed, and have breakfast.”
“You’re cooking?” I raised a brow. Was my lack of sleep causing me to hear things? “For me?”
She snorted, somehow making the annoying gesture sound adorable. “You wish. Cook for yourself. I’m not your maid.”
She disappeared out the door, leaving me with nothing but her scent, a towel wrapped around my hips, and a massive tent underneath it all because all I could think about was my little sister wearing a maid’s uniform.

School was… weird.
People kept giving me double or triple glances and I swore I was being gossiped about. I saw groups huddled together inside classes looking at me, and I spotted more while walking between lecture halls. They would talk in hushed tones, only to quiet down when I neared them.
I didn’t see Ava for hours. She was blue ticking my texts, and I kept hoping to catch sight of her, to no avail. My sister was constantly on my mind and I couldn’t concentrate in class, my head a whirl, replaying the hazy events of last night over and over. I was constantly hard for Ava, yet my sister wasn’t even near me.
Pathetic.
When it was finally time for lunch break, I almost sprinted towards the cafeteria. Maybe she would be sitting at the VIP table and we could sneak off and fuck like she had promised me last night. Ava made a lot of promises when we were fucking.
I shouldn’t even be thinking of sex with how sore my body and cock were, but the more I went on my day without my sister, the more I realize how utterly hooked I was for her. I kept licking my lips, hoping for a residue of vanilla, even sniffing my skin, wishing that her scent had stayed on me for longer.
I was an addict looking for a fix only my little sister could give me.
Was this the reason every single one of Ava’s exes shattered apart when she broke it off? I completely understood it now. Ava knew exactly how to work a cock to maximize pleasure and she had the grippiest fucking pussy ever. It was no surprise I hadn’t seen Kevin in a week, and I heard rumors he took a break from the football team.
I was determined to not allow my sister to break my heart. She had already done that so many times already, and I swore it would never happen again.
I didn’t even notice the person walking towards me until I bumped into her.
“Woah!” The girl stumbled off to the side and lost her balance. I grabbed her hand just in time before she fell, murmuring apologies as I stared up at green eyes and shoulder-length blonde hair curled up in a familiar French twist.
Vanessa.
She looked up at me, the anger in her emeralds disappearing as she recognised me, switching gazes between my left and right eye.
“Aaron?” We were still holding hands, and she wasn’t letting go. “Wow, look at you. I almost didn’t recognize you.”
“Really?” I had no idea what to say or handle any type of small talk. “Umm… Vanessa, have you seen my sister?”
“Ava?” She sniffed. “Nope.”
She didn’t offer more. And she was still holding my hand.
“You know….” She rubbed slow circles over the back of my hand. “I heard the gossip about you and I can now confirm that they are true.”
“Gossip?” I frowned. “What gossip?”
I was never talked about, so her revelation caught me by surprise.
She batted her lashes, her painted lips curling into a smile. “That you have changed. That your family’s pristine genetics finally caught up to you and you became…” She ran her tongue along her bottom lips. “…hot.”
“Uhh…”
What the hell do I even say to that?
Vanessa finally let me go, but she trailed her fingers along my arm. “Have you ever had a girlfriend, Aaron?”
“Girlfriend?” I blinked. I thought of Ava. “Umm… I… I don’t—”
“Do you ever feel lonely in your bed?” She exhaled deeply, gazing at me. “Mine’s pretty cozy.”
I couldn’t believe I was being hit on. It was a surreal experience and multiple replies gathered in my mind. All of them cringeworthy.
Had Vanessa accidentally taken the love pill? That was the only logical conclusion in my head. I just remembered I had an extra pill sitting somewhere in one of my drawers back in my room. But there was no way Vanessa could have taken it because she hadn’t come to our condo recently, unless she had somehow broken in.
I started to reply, but I caught a whiff of delicious sweetness, freezing my tongue in place. Ava came up beside me, eyeing Vanessa, who was now squeezing my biceps.
“Did I give you permission to touch my brother?” Her tone was like a hot knife through butter, and I caught several groups of people halting their conversations to look at us.
Vanessa flinched, but she didn’t drop her hand. Her smile slipped as she met my sister’s gaze. “Aaron’s single, isn’t he?”
Ava crossed her arms under her breasts, jutting them out. “So?”
“Ava, do I need your approval to date your brother, too? You’re not the queen of everything. Not everyone belongs to you.”
“Vanessa,” my sister dropped her voice, making every word clear. “Let. Him. Go.”
They did a staring contest for a few seconds, but finally Vanessa looked to the side and dropped her grip on my arm.
“Whatever,” she muttered, turning on her heels and storming off. A small crowd had formed around us and they parted to let her through.
Ava seemed to pay no mind to the attention she had drawn. Taking my hand, she led me through the mummering crowd, exiting the main building of the school and heading straight towards the technology building. I knew where she was taking me and every step had my heart thumping harder and faster.
My sister stayed silent, bringing me to the third floor and through long, dark corridors, finally stopping in front of the door named ‘Lab thirteen.’ She fished out a key from her purse and unlocked the abandoned lab, ushering me in with a death glare.
“Ava,” I sputtered out as I entered the lab. My sister stepped in and closed the door shut behind us, the lock clicking in place. “Look, Vanessa bumped into me and—”
“Sit.”
I stared at the lone chair she was pointing towards.
“What?”
“Sit.”
Her voice whipped through the air.
“Ava.” I shook my head, raising my hand to defuse the situation. “Can we not—”
“Aaron,” she cut in. “I’m going to say this one last time.” She paused to allow her words to sink in. “Sit.”
I sighed loudly, throwing my hands up and shrugging. “Whatever.”
I walked towards the chair and sat down, feeling annoyed that I was letting my little sister push me around like this.
It should be the other way around. I was the big brother.
Ava strode towards me and I jerked against the chair when she sat down too, straddling me, our lips inches away.
I gripped her ass automatically, squeezing her cheeks through her uniform skirt, sighing happily as plumpness filled up my palms.
My sister wrapped her hands around my neck and dipped forward, wrapping her lips over mine, offering me her delicious flavor and sending me tethering at the edge of heaven.
She stroked my tongue with hers once, twice, before dipping out, gazing at me with a blank expression. I had no idea if she was mad or horny. Maybe a bit of both.
“You like Vanessa, don’t you?”
I shook my head, drunk from her taste, dizzy from her scent. “I like you more. I love you.”
“You love me?” Ava rose slightly, her hands dipping under her skirt. Black lace peeked through as she pulled her panties down her milky thighs. “If you love me, you’d have told the vulture to fuck off as soon as she looks at you.”
“Ava, I—”
“Shh.” She sat back down, silencing me with a scorching kiss, sucking on my lips with undeniable passion. “Shh. Don’t say anything. It’s okay.”
My sister pulled away, a saliva strand connecting our lips. She smiled and broke the final connection between us with a flick of her tongue.
Fuck. I just want to fuck her. Right fucking now.
“Ava.” Her name came out in a moan when she began unzipping my school pants, sliding it down my legs. I hissed when she hooked her thumbs under my briefs and then brought down that layer of fabric, leaving both our sex bare—and soaking wet.
I expected my sister to play one of her games. Maybe tease me until long minutes turned into unbearable hours.
But Ava was having none of it. Wrapping her arms around my neck once more, she held my gaze in a magnetic pull and shifted forward and down, impaling my cock into her dripping folds.
“Fuck!” I spat out, the sensations both painful and pleasurable from how sensitive my cock was. “Ava!”
“Shh…” My sister looked up at the ceiling, her eyelids fluttering, her lips parting. “Doesn’t this feel amazing, Aaron? So fucking amazing?”
“Yes,” I nodded, gritting my teeth as she began rolling her hips back and forth. “Yes, it does.”
I slipped my hands under her skirt, rather feeling her bare flesh than pleated fabric. Her ass felt warm, but her pussy was scorching, burning my cock with raw pleasure.
“Do you like how I squeeze you?” Her high-pitch voice was back, giving me all sorts of thoughts. None of them innocent. Her pussy clamped down around me and I swore I saw stars.
“Yes. Yes.” I tried to kiss my sister, but she leaned back. “God—Ava!”
I couldn’t have her lips but I had access to her plump cheeks. I squeezed my sister’s ass as hard as I could as she bounced up and down on my cock, splitting my body in half. When a cry bolted from my lips, she returned and planted her lips close to my right ear, licking my earlobe.
“Are you close, Aaron?” she whispered darkly. “Tell me if you’re close.”
“Wait,” I choked out, squeezing my eyes shut, my nails digging into her ass cheeks. “I’m close. I’m close. A few more seconds and—”
Ava stood up, my cock withdrawing from her heated folds with a wet ‘plop’.
“Wait.” I opened my eyes, eyeing my sister. “What are you doing?”
She sniffed, lifting her panties back up. “You can go to Vanessa and beg her to finish you off. Tell me if her pussy is any better than mine.”
“Ava,” I groaned. “Please. Come on.”
The pressure inside me was fading away, even when I started jerking myself off. The difference between touching myself and being inside Ava was galaxies away. No matter how hard I pumped myself, the edge my sister created was quickly evaporating.
Fuck. Why was she such a jealous bitch?
“Look,” I sighed. “Ava, look. Please. All I did with Vanessa was accidentally bump into her because I was thinking about you. I grabbed her when she was about to fall and she wouldn’t let me go. I swear to God, I didn’t think of her in any sexual way. Not the way I think about you.”
My sister grabbed her purse she had left on one of the computer benches and fished out her phone. Her fingers tapped on her screen in a blur and a few seconds later, my phone vibrated in my pocket.
I frowned. “What is that?”
Ava crossed her arms, giving me the silent treatment.
I continued jerking myself off hoping I could get off, but it was fruitless. The bar was set so high after last night. I couldn’t orgasm by myself anymore, no matter how horny I was.
Sighing again, I gave up and took my phone out, glancing at the text my sister had sent me.
It was a number.
I looked back up. “What? What is this?”
She grabbed her purse and walked away. “Vanessa’s number.”
“Ava, wait.” I pulled my briefs and pants back up, stumbling after my sister and grabbing her arm. She stopped, but didn’t turn around.
“Okay, look.” I swallowed a lump of saliva, still tasting her vanilla inside my mouth that had coated my tastebuds. “I’m sorry, okay? I’m sorry for looking in Vanessa’s direction. I’ll never look at her again. Can you please stop being mad at me?”
Ava was still for a while and hope blossomed in my chest. But it all came crashing down moments later when she shook my grip off and unlocked the door, swinging it open and slamming it in my face, the sound of the slam echoing around the lab.
“Fuck!” I shouted, slamming a fist against the wall. Pain shot through my arm, but it couldn’t compare to the agony of a raging erection that was leaking so much pre-cum, jerking painfully, aching to be back inside a particular girl’s addicting, heated depth.
Why was Ava so fucking childish? Why was my sister so damn possessive? She was at lunatic girlfriend levels. No, even worse. No wonder she couldn’t hold down a relationship for long.
The only reason Kevin and her were together for two years was because he was the most popular person in school when we first joined. Seducing Kevin to break up with his previous girlfriend and then being with him shot her to the number two spot instantly. And now that Ava had overtaken him, she had no use for the jock anymore, thus the breakup.
“Fuck,” I screamed, louder this time, spitting the curse out.
Ava was such a jealous bitch.
Maybe her accidently swallowing the love pill wasn’t such a blessing after all. Maybe Vanessa would have been a better girlfriend.
Maybe…
Maybe I ended up with the wrong sister.
Lucia.
She was older than me. Seven years my senior, to be exact. But that only meant more experience, and more importantly—maturity.
Lucia wouldn’t be a headache like Ava. She was sensible, mature, and fucking sexy.
I had been telling the truth when I told Ava she was the most beautiful woman I had ever seen. Vanessa couldn’t come close, but Lucia?
She was a good second. And who knows? If she fucks better than our younger sister, did it really matter if Ava was a tad bit hotter?
I had one pill left, and I needed to make a choice now.
I dialed Ava’s number and pressed the phone close to my ear, praying for her to pick up so that I wouldn’t need to deprave further. Commit one more sin. Fuck another sister.
But Ava made it clear she didn’t want to speak to me. She declined the call, and I was left staring at my phone screen, seeing my frown in the reflection.
Maybe I had chosen the wrong sister after all.
