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!”
And her whole body started violently shaking as a continuous moan filled the room.
That ripped Mia out of her trance. By what I saw in her expression, it was clear that she had made up her mind about all of this, and now she wanted to join in. She jumped up, lay on her back in front of Ava, and spread her legs wide. Then she grabbed Ava’s hair and shoved my sister’s mouth into her pussy.
“Keep going, Muffin!” she commanded, before shifting her attention back to Ava. “Now eat my cunt, Babygirl! Your brother’s going to violently ram his fat hard cock into you until you make me come! But you better hurry up, because if you come before me, I’m going to torment your pussy until you scream as punishment!”
