When I returned home that Tuesday evening, I could immediately feel that the atmosphere had shifted. It wasn't a negative tension; on the contrary, the air felt charged with a new, almost tangible electricity. During dinner, Mom and Sophia exchanged glances full of secrets, restrained smiles, and a synergy that went far beyond the friendship they had previously built. They looked like two accomplices who had just pulled off a bank heist and were savoring the prize.
Later, when we went up to the master bedroom—which had already become our ritual—I decided not to let it slide. I sat in the center of the king-size bed, crossing my arms, while the two of them finished getting ready.
"Alright, you two are being very mysterious tonight," I commented, laughing softly. "What happened while I was out?"
Sophia looked at Ana, giving a mischievous giggle, and then turned to me, crawling across the mattress like a cat.
"Let's just say we broke the final remaining barrier in this house, little brother..." Sophia whispered, sitting on my lap and wrapping her arms around my neck. "We discovered that your harem can get even better."
Mom approached right after, sitting down beside us. Her cheeks were slightly flushed, but her eyes exuded a delightful sense of freedom.
"We talked a lot about the past, about our fears... and we ended up letting ourselves get carried away, my love," Ana confessed, her voice soft and affectionate. "We kissed. And we did much more than that. The two of us gave ourselves to each other this afternoon, Lucas. We discovered that we are bisexual, and that we love each other even more now."
My heart raced. The vision of having the two women in my life not just getting along, but now sharing lesbian pleasure, was the ultimate realization of every man's wildest fantasy.
"Are you guys serious?" I asked, feeling my dick wake up instantly beneath my pants.
"Do you want us to prove it?" Sophia challenged, wearing a thoroughly satisfied smirk.
Without waiting for my answer, Sophia turned to Mom. Before my wide eyes, the two drew close and locked lips in a deep, slow, and desire-filled kiss. Their tongues intertwined with an astonishing ease, while Sophia's hands squeezed Ana's mature waist, and Mom caressed her daughter's hair. The wet, smacking sound of that lesbian kiss echoed through the bedroom, making my blood boil.
The night transformed into the most profane and intense threesome of our lives. Under my eyes and commands, the two fully explored each other on the bed. I watched, hypnotized, as Mom lay on her back and Sophia buried her face between her thighs, lapping at Ana's intimacy with a wild urgency while Mom gripped the sheets in pure pleasure. Afterward, I inverted their positions, having Ana use all her mature experience to suck and finger her daughter, covering Sophia's young body in caresses before I stepped into the action myself, possessing them one at a time while they continued to kiss and touch each other beneath my body.
When we finished, the three of us were sprawling across the sweaty sheets, exhausted and completely connected. It was then, while I was stroking both of their hair, that Sophia planted the seed for the future.
"You know, Lucas... our spacious house feels a bit empty for just the three of us," she commented, tracing circles on my chest. "There's this friend of mine from college, Bia. She's beautiful, a bit of a good girl, but she's always asking me about you whenever she comes over. Mom and I were talking... I think she would be the perfect bait for our club."
"A straight girl?" I asked, arching an eyebrow.
Mom lifted her head, giving a knowing smile.
"Leave that to us, my dear. The two of us know exactly how to use our charm to disarm a woman. Tomorrow she's coming over to study with Sophia. You just need to follow our lead."
The next afternoon, the plan went into motion. Beatriz arrived for the Business Administration study session. She was a beautiful girl with fair hair and a more reserved style, clearly a "good girl." But the moment she stepped through the door of our spacious home, the culture shock began.
The house's atmosphere was purely libertine. Sophia greeted her wearing nothing but a pair of tiny denim shorts that exposed the lower curve of her cheeks and a miniscule top. Mom was in the kitchen wearing a super tight strap minidress, no bra, with her nipples prominently marking the fabric with absolute naturalness. I was in the living room, shirtless, pretending to work on my laptop.
Bia swallowed hard at the entrance, visibly flustered by such freedom and the exposed bodies, but she tried to mask it, greeting everyone with a timid smile. Her eyes, however, inevitably wandered to my bare chest every now and then.
We all sat in the spacious kitchen area to chat before the two of them started studying. The mood was light, with Sophia and Ana dropping subtle compliments toward Bia, making her blush every five minutes. That was when Mom gave the invisible signal to Sophia.
"Oh, goodness, we forgot to buy sodas and snacks for your study afternoon," Ana commented, tapping her forehead in mock forgetfulness. "Lucas, my love, wouldn't you do us that favor? Go to the neighborhood market and buy some nice treats for Bia."
"Sure, Mom," I replied, catching onto the game instantly. I stood up, grabbed the car keys, and gave them a discreet wink. "I won't be long."
The moment the front door clicked shut, sealing my departure, Bia let out an audible sigh, relaxing her shoulders a bit on the kitchen stool.
"Wow... your brother has changed a lot, hasn't he, Sophia?" Bia commented, looking toward the door I had just walked through. "He looks... so different from when I first met him. More manly, I don't know."
Sophia laughed out loud, opening the fridge and pulling out a bottle of chilled white wine, while Mom grabbed three crystal glasses from the cupboard.
"Oh, you have no idea how much he's changed, Bia," Sophia winked, pouring the drink for her friend. "Lucas took the reins of this house. He takes very good care of us."
"Absolutely," Ana chimed in, sitting at the table slightly further back, maintaining an inviting, mature posture. "Having a real man around changes everything, dear. But tell me, how are things at college? Sophia told me you've been a bit stressed this week."
Bia took a healthy sip of the wine, feeling the environment become incredibly comfortable. The subtle transition from discussing my new physique to a warm chat about her own life made her let her guard down completely.
"A bit... I ended a horrible relationship a month ago, and focusing on studying has been hard," Bia confided, swirling the glass between her fingers. "Sometimes I feel like guys our age are just so immature."
Sophia moved closer, sitting next to her without any rush. She gently placed her hand on Bia's arm—a purely comforting touch, from friend to friend.
"Immature men only cause headaches, Bia. You are so beautiful, so smart... you deserve someone who knows how to value you entirely," Sophia said, looking into her eyes with genuine affection.
"Exactly," Mom added, giving a sweet smile. "Beautiful women like you need real affection, real attention. Sometimes, what we need is just to relax in a place where we can be ourselves, without any judgment. You are at home here, Bia."
Bia smiled, feeling her cheeks warm up, not from embarrassment, but from the pleasant heat of their combined compliments. She looked at Sophia and then at Ana, feeling a delightful, subtle feminine complicity begin to envelop her in that kitchen. The straight girl's barriers were being dismantled with pure elegance.
