The silence that settled over the house after the whirlwind in the dining room was almost surreal. A few hours had passed, and the exhaustion from the sex with Mom had left me thoroughly relaxed, lying in bed wearing only a pair of light shorts. The adrenaline had dipped, but the electricity in the house's atmosphere remained thick and palpable.
I was staring at my bedroom ceiling when the soft click of the doorknob broke the quiet.
The door opened slowly, revealing Bia. To my surprise, my girlfriend was completely naked. Her hair fell somewhat messily over her shoulders, and being the extremely timid girl she had always been, she was trying to cover her breasts with crossed arms, while one of her hands reached down bashfully to shield her pussy. Her cheeks were flushed an incredibly deep red, and she kept darting her eyes away, unable to look directly at me at first.
"L-Lucas..." she stammered, her voice almost entirely failing her. "The house was so quiet... and after everything that happened downstairs... I couldn't stop thinking about you."
Seeing her like that, with all that innocence and shyness contrasting with her gorgeous, naked body, made my blood boil all over again. I sat up in bed and extended my hand toward her with a welcoming smile.
"Come here, Bia," I called softly.
She took hesitant steps, but the moment she took my hand, I pulled her onto the mattress. Bia let out a startled gasp that quickly turned into a low moan as I laid her on her back. We began foreplay gently; I used my lips to trace a warm path down her neck, moving over her firm breasts and sending shivers across her skin. Her hands, still trembling with embarrassment, gradually let go and dug into my shoulders. I could feel how warm and surrendered she already was to the moment, slowly forgetting her own shyness under my touch.
It was exactly at the moment when I was moving my kisses down toward her stomach, right on the verge of tasting her intimacy, that the bedroom door was pushed wide open without a single warning.
Sophia walked into the room. My sister was wearing only a tiny pair of black panties, her full breasts completely bare and exposed, and she had a totally distracted expression, messing with her hair. She had absolutely no idea that her college best friend was already in here with me.
Hearing the noise, Bia jolted up on the bed, her eyes widening in pure panic as she tried to frantically cover herself with the sheets, her face burning with intense shame.
Sophia froze in her tracks, her brown eyes blinking in surprise as she caught us in that position. A sly, thoroughly mischievous smile began to etch itself onto my sister's lips as she scanned the scene.
"Well, well..." Sophia murmured, closing the door behind her with her heel, making no move whatsoever to leave or cover up. "Looks like no one invited me to the fun."
Bia’s face flushed even darker, if that was even possible, burying her face against my shoulder to hide from her best friend's predatory gaze. But Sophia didn't care about Bia’s shyness. With a slow, deliberate swing of her hips, she approached the edge of the bed, her eyes locked on my groin. She climbed onto the mattress and instantly settled her bare knees on one side of my hips, while Bia remained on the other.
The lingering awkwardness melted away into pure, raw heat as Sophia reached down, her soft fingers gripping my shorts and pulling them down alongside my underwear, freeing my rock-hard, throbbing cock. Bia, seeing her best friend taking charge with such confidence, let out a shaky breath, her initial embarrassment turning into a desperate desire to please.
Sophia leaned in first, capturing Bia’s lips in a deep, wet kiss right over my chest. The sight of my sister and my girlfriend kissing—their bare breasts rubbing against each other—sent my arousal through the roof. While they swapped saliva, Bia reached down and guided the head of my rigid member directly against her dripping, tight opening.
With a sharp intake of breath, Bia slid down, impaling herself fully on my length.
"Ahhh... Lucas!" Bia cried out, her head snapping back, her tight walls squeezing me mercilessly as she began to ride me with a wild, desperate rhythm.
Sophia didn't just watch. She moved behind Bia, wrapping her arms around her best friend’s waist, biting and licking the nape of Bia’s neck while her hands reached around to massage her breasts. The room filled with the heavy rhythm of flesh slapping against flesh and the chaotic symphony of their high-pitched groans.
"Louder, Bia... let me hear how much you like my brother's dick," Sophia whispered dirtily into her ear, using her fingers to stimulate Bia’s clit from behind while I thrust upward with extreme intent.
The stimulation was a complete sensory overload. I gripped Bia's hips, pounding into her from below with increasing force. The burning sensation of the imminent climax rushed through my veins like wildfire. Feeling my girlfriend’s desperate tightness while my sister egged her on pushed me straight over the edge quickly.
"Bia... I'm gonna cum!" I warned, gripping her waist tightly.
I delivered three final, brutal, deep upward thrusts, burying it to the hilt, and discharged with violent force. I came heavily inside Bia, hot, massive jets flooding my girlfriend’s womb. She let out a sharp shriek and peaked in an intense orgasm, her entire body trembling as she emptied herself on top of me, collapsing with a heaving chest against my lap.
As Bia slowly pulled away, my member slid out of her coated in a glistening mixture of semen and lubrication. Sophia, watching everything with eyes gleaming with lust, wasted no time. She slid down my body and positioned herself between my legs.
Without hesitation, my sister wrapped her lips around my still-rigid cock, giving me a deep, greedy clean-up blowjob. Her tongue worked firmly, sucking up all the semen dripping down the shaft and cleaning the head with wet slurping sounds that echoed through the room, making me gasp at the immediate return of the stimulation.
When my member was completely clean and throbbing even harder, Sophia looked up with a wicked gaze, pulled her black panties to the side with one hand, and positioned herself. With a determined, firm movement, she dropped her hips all at once, taking my entire cock inside her, swallowing every single inch to the hilt in her familiar, tight heat.
"Ahhh, little brother..." Sophia arched her back with a heavy groan, starting to dictate a new savage rhythm on the bed.
My sister bounced with a delicious aggressiveness, locking onto me tightly with her internal walls. Beside us, Bia, still trembling and recovering from her own orgasm, lay on her side, propping her face up with her hand as she watched us with a complicit, aroused smile. Sophia leaned forward, resting her hands on my chest to gain more leverage, making her full breasts bounce in the frantic rhythm of her riding.
The fast friction and the heat of my sister's body, combined with the view of Bia watching us so closely, brought on a new, uncontrollable wave of pleasure. My hips began to automatically thrust upward, meeting every downward drop of Sophia's with brute force.
"Lucas... it feels so good... put it all inside me too!" Sophia panted, her eyes half-closed in pure pleasure, accelerating the movement to the absolute limit.
I couldn't hold it back for long. The refractory period simply did not exist in the face of that double depravity. I firmly gripped Sophia’s waist, locking her body against mine at the deepest point of penetration.
"Sophia... I'm gonna cum!"
With one final, violent contraction, I discharged again. I came with overwhelming force deep inside Sophia, filling my sister's womb with a new, massive wave of hot semen. Sophia let out a long, sharp scream, rolling her eyes as her entire body went into convulsions, having a crushing orgasm that milked my cock to the very last drop. She collapsed exhausted onto my chest, our hearts beating in the same accelerated rhythm, while Bia leaned in to embrace us both from behind, sealing that wild threesome in absolute complicity.
