“Come closer, Muffin. Explore your sister’s body.” she whispered, and I felt my dick twitch.
I stepped forward and placed my hand on the inside of Ava’s thigh, feeling her muscles twitch when my fingertips made contact with her skin. My hand slowly moved upwards and, as my index finger gently scraped along her labia, Mia’s hand moved inwards to assist my own in its task to probe my sister’s sex. As my fingers found Ava’s clit and lightly pinched it, Mia’s fingers moved up along Ava’s folds before she pressed the tip of her middle finger against Ava’s butthole, not strong enough to penetrate it, but firmly enough to let Ava fear an attempt at dry probing.
Encouraged by that display, my own fingers moved away from Ava’s clit to part her inner lips. We could actually hear how wet she was. When my fingers reached Ava’s entrance, I pushed two of them inside while Mia started dragging her fingernails along my sister’s spine. Ava immediately reacted by releasing a soft moan. The display of her writhing body, as I slowly fingered her, was spectacular. I never had such a great view when I did this before, and could see Ava’s skin being pulled towards her center as I shoved my digits as deep into her as I could.
After about a minute or so, Mia made Ava kneel upright on the mattress, leaned down herself, and started kissing her. Ava, still wearing the sleeping mask blocking her sight, tried to return the kiss but more than once puckered her lips towards the air.
Then Mia moved her kisses down Ava’s body, along her collarbone and finally onto her nipples. That looked so incredibly sexy that I wanted in on that. So, I kneeled behind Ava myself, moved her head to lean to the side, and started kissing her neck. But then I felt Mia’s hand on my shoulder, gently guiding me so my kisses trailed along Ava’s neck, over her cheek, and finally to the corner of her mouth.
I glanced at Mia, making sure this was really what she wanted, and saw her nodding in encouragement. So, with Ava’s naked ass pressed into my groin, my hand slipped under her chin and moved her head to face straight at the ceiling, before I leaned forward and kissed my own sister on the lips, right in front of my girlfriend.
Mia, in turn, didn’t wait long, and simply joined in. Three mouths, and very soon three tongues, battling for contact with each other. From then on, we couldn’t wait anymore.
I jumped off the bed and started undressing myself. My rock hard cock pointing straight at the objects of my desire. While I was removing my clothes, Mia helped Ava get off the bed and kneel on the floor instead. As soon as I was naked, she placed both of her hands on either side of Ava’s head, and pointed her face at my groin.
“Put your hands behind your back and open your mouth, Babe.” Mia whispered, and Ava complied. She opened her mouth with a moan and even stuck out her tongue in anticipation.
There she sat, my big sister, with her perky tits jetted outwards to put them on display, her mouth wide open and her tongue hanging out, waiting for me to use her mouth as my personal fuckhole. And I didn’t wait long. I stepped forward, placed the tip of my cock on her tongue, and she immediately started sucking me with loud moans.
“Yes, Babe, taste him. Taste your brother’s cock. Isn’t it the best thing you ever had in your mouth?” Mia asked sinfully, and Ava moaned her approval as the speed of her bobbing head increased.” Just wait until he gives you his extra tasty cream!”
And with that, Mia leaned past Ava to twirl her tongue around my nipple, while simultaneously placing a hand on the back of Ava’s head. She started pushing Ava’s mouth down my pole until I felt the head of my cock past her tonsils and heard her choke, but she never tried to pull back or even resist Mia’s guidance.
“Just remember now, Muffin, she likes it rough.” Mia said, before grabbing Ava’s head with both hands to move it forcefully now, instead of just guiding its direction.
There I stood, in my bedroom, with my girlfriend forcefully fucking my big sister’s head onto my cock.
“GWACH - GWACH - GWACH” was all I could hear from Ava, as the head of my cock hit the back of her throat over and over again, every time Mia pushed her into my groin with a big grin on her face.
“Yes, Babygirl. Please your brother.” Mia said through her own panting. “God, this is so fucking hot!”
I had to agree, and grabbed a handful of Mia’s hair to pull her face towards me. We passionately kissed, our tongues wrestling, while she used Ava’s mouth to please me. Then she suddenly leaned down, pulled Ava’s head off my cock, and started blowing me herself. Ava’s face was now shoved into my balls, which she instantly started licking with gusto.
Then I felt my cock shove back into Ava’s throat for a forceful fucking, and back into Mia’s mouth for a luscious blowjob, and back into Ava’s throat as Mia kept alternating between those two options. I was lost in my lust, all thoughts about the implications and possible consequences forgotten, wiped from my consciousness.
But then it happened. Mia jumped up, her eyes wild, and pushed Ava’s head onto the ground while she was still on her knees, so her ass was pointing up.
“Come behind her, Muffin!” she commanded, and I eagerly complied. She motioned for me to kneel behind Ava and grabbed my cock, pointing it towards my sister’s sopping wet hole, and used her other hand to squeeze my ass. “Now I’m going to get a condom and then you will finally plunge that fat cock of yours into your sister.”
“No!” Ava shouted. “Fuck the condom! Just fuck me, brother! Please! Now! I need it! I’ve waited for so long! PLEASE JUST FUCK ME!”
Mia’s eyes grew big and her entire body grew still.
“But ... Ava ... He’s...” she stammered.
“I’m on the Pill, Mia! It’s Okay! Please, I want to feel my brother inside me!” Ava pleaded, and Mia’s eyes jumped between my eyes, my cock, and Ava’s pussy. “I want my brother to feel me!”
“Okay.” I just said. “I’ll fuck you raw, Princess.”
Ava moaned loudly upon hearing me call her by my intimate nickname for her. The nickname that reminded her so much of how our relationship had changed, by hearing how the intonation I used had changed.
If at all possible, Mia’s eyes grew even bigger. She just stared at me for a few seconds, before I could see that lustful glint appear. She kept her hold of my cock, still pointing it at Ava’s entrance, while the hand on my ass finally started pushing me towards it. Slowly, painfully slowly, I closed the distance, but she stopped pushing me as soon as she saw the tip of my cock make contact with Ava’s sensitive skin. Then she just looked at me.
I grabbed Ava’s hips with both hands, looking Mia directly in the eyes while she kept holding my cock in place, before pulling Ava with all the strength I had back into me, burying myself inside her at once. Ava wailed in pleasure.
“GAAAAWD YES! THANK YOU! THANK YOU, LITTLE BROTHER! FUCK ME!”
And I did. Too worked up from what had happened so far, and remembering that she liked it rough, I mercilessly slammed into her repeatedly. With every forceful thrust I felt my tip pass that tight ring inside her again, and every time I felt that extra tightness around my tip, Ava let out a shrill shrieking sound. I was a little concerned that Mia might be put off by that display, but instead she seemed to be getting turned on even more, as she panted loudly while watching me brutally fuck my own sister.
“That’s how you like it, Princess? Me fucking you however hard I want?” I asked through gritted teeth.
“YES! YES! FUCK! YEEEEES! USE ME, LITTLE BROTHER!” she screamed without inhibition. We continued like this for a few minutes before I could feel her clamping down on me. “CUMMING! I’M COMING! OH GOD! I’M FINALLY COMING ON MY BROTHER’S COOOOOCK!”
