Two weeks later, Anastasia and I were sprawled across the couch, a dim movie casted a soft shadow across her face. She turned to me, her voice dropping into that low, playful murmur I’d come to know too well.
“So,” she said casually, “Why don’t you spend another night with Grace?”
I froze for a beat, heart tightening as I tried to read her tone. Was this a trap?
“No way,” I said quickly, then softened my tone. “Grace’s incredible ... smart, sexy, passionate. Honestly, anyone would be lucky to be with her. I’d love to see her again, but...” I paused, searching for the right words.
“She’s still figuring herself out. You’re different, you’ve got your shit together. I just don’t want to lead her on. A hookup is one thing, sure, but ... I was her first. And I think she might like me more than she should.”
The air between us thickened, like I was stepping into a fog of uncertainty. I met Anastasia’s eyes, steady, unreadable.
Her lips curled into a sly, mischievous grin.
“What if you could have both of us?”
I blinked. “Wait, what?”
Her grin widened as she tossed a lock of hair behind her ear. “I mean, if you’re not into it, that’s okay, but...”
“No, no, it’s not that, I just...” I trailed off, caught between disbelief and rising arousal. My body had already answered before I could find the words.
“Picture this,” she whispered. “Next weekend. The three of us. Motel room. All night. All day.”
The image hit me like a jolt of electricity: Anastasia, with me, together, wrapped in warmth, lust, and laughter, a weekend of passion with no limits. My pulse thudded in my ears. That Grace was joining us made it even sexier, almost.
“You’re serious?” I asked.
Anastasia leaned in closer, her voice a sensual hum.
“Oh yeah. And maybe, when you need a break, Grace and I can entertain each other.”
She traced her finger along my chest. “I’ve heard you’re irresistible when you’re not trying to finish. And let’s be honest, you adore going down on a woman, don’t you? That’s rare. Most guys fake enthusiasm. You? You worship it...
Her smile deepened, sultry and wicked. “And don’t most guys get off just watching two women together?”
Then, slowly, deliberately, she ran her tongue across her lips, a tease so full of promise it made my breath catch.
“Imagine Grace, between my legs, spreading my pussy wide, before she slyly slide her tongue, from my anus up between my wet lips and end up licking my hard clit...”
I swallowed hard, my throat suddenly dry. The room seemed smaller, hotter. My jeans felt tighter by the second.
“You’re killing me,” I muttered, my voice half-laugh, half-moan.
Anastasia leaned in, her lips brushing my ear. “Good. That’s the idea.”
She pulled back just enough to look me in the eyes.
“But only if it’s what you really want. No guilt. No confusion. I like Grace. A lot. But this only works if we’re honest about everything, no games, no weirdness.”
I nodded slowly, trying to keep up with the pace of her words and the heat behind them. “You’re saying we could ... all fuck? For real?”
I looked at her, really looked at her, as her words settled in the air between us. “Not just fuck,” she said, eyes steady. Then, with a smirk that curled into something playful and knowing, she added, “Well, that for sure, but connection. Trust. Freedom, even. Something that belongs just to the three of us.”
I let that sink in, turning it over in my mind. What did that mean, exactly? I knew what I felt, yes, the raw, physical hunger was there, sharp and undeniable. I wanted her; I wanted Anastasia, that was the truth. I wanted every inch of that delicious, body of her and the thought of her pussy made me so hard. But, somehow, it wasn’t just about fucking anymore.
It was about what came with it: the vulnerability, the permission to feel everything fully. It was about opening to something bigger than lust, this rare, fragile bond we could shaping together. And that scared me a little ... but it also thrilled me in a way nothing else had.
I looked at her, and saw more than the usual mischief in her eyes. There was fire, yes, but behind it, something clearer. Intent. She wasn’t teasing for the sake of it. She was offering something real.
“You’re amazing,” I said, voice barely above a whisper.
Anastasia grinned, unabashed. “I know.”
She climbed into my lap with slow confidence, her lips brushing against mine, just enough to set me alight, not sufficient to satisfy.
“So ... should I text Grace? Tell her to keep next weekend open?”
My hands found her hips, gripping them with hungry anticipation. “Text her now. Tell her to make no other plans.”
She laughed, the sound like a promise wrapped in warmth, and pulled out her phone. “You’re about to be a very lucky man, lover.”
I watched her thumbs move across the screen, fast and sure. Then the brief silence, tense and buzzing, before her phone vibrated in her hand.
Grace: Hell yes. Count me in. Just tell me what to pack.
Anastasia looked up at me, eyes gleaming. “Looks like it’s on.”
Anastasia tossed her phone onto the coffee table and turned back to me, straddling my lap fully now, her hands cradling the sides of my face. “You realize this will going to change things,” she said, her voice softer, but no less charged.
“I know,” I replied, my hands settling on her thighs. “And I want that. I want us, whatever form that takes.”
She studied me a second longer, then nodded once, decisively. “Good. Then we do this right. No secrets. No jealousy. Just honesty. And ... no telling your buddies...”
Her mouth found mine again, this time deeper, slower, a kiss that promised everything and asked for nothing but surrender. I sank into it, feeling her melt against me, our bodies locking into that familiar, perfect rhythm.
When we finally broke apart, she pressed her forehead to mine.
“We’ve got five days to get ready,” she said. “I want to do it right, pack some sexy stuff, music, candles. Maybe even a toy or two that I am sure Grace’s never seen.”
I smirked. “Are you saying this is going to take planning?”
“Oh, definitely,” she said with a grin. “Grace’s about to be ruined for normal weekends forever.”
We spent the rest of the evening curled together on the couch, limbs tangled, breath syncing, the TV long forgotten. Every now and then, Anastasia would mention another idea, lingerie she might wear, games we could play, things Grace had hinted she wanted to try.
I didn’t sleep much that night, not from anxiety, but from the electric hum beneath my skin. I was alive with energy, with anticipation, with something that felt almost like reverence.
When I finally drifted off, Anastasia curled beside me, her bare shoulder nestled against my chest, I dreamed of the three of us. Firelight. Laughter. bare, wet pussies, licking, sucking my cock in tandem ... Not something we’d stumbled into by chance, but something we were choosing, deliberately, together. Something rare. Something beautiful.
I woke later as Anastasia stirred. She rose from the couch with a sly grin, stretching just enough to remind me she knew exactly the effect she had on me. Then she leaned in close, her voice low and laced with mischief.
“Think you can handle both of us next weekend?” she murmured, fingers closing around my semi-hard cock.
I swallowed, grinning crookedly as arousal surged. “Only one way to find out. Want to give me a practice run now?”
She laughed, wicked and light, then turned and walked away.
“I’m taking a shower,” she tossed over her shoulder. “Try not to explode, you horny little devil.”
Maybe she hadn’t exactly invited me, but she hadn’t told me not to, either.
“Need someone to wash your back?” I called.
Her laughter echoed through the steam. “Only if you behave ... which we both know you won’t.”
I gave her my best wounded look. “Me? Never.”
She grinned over her shoulder, one eyebrow raised. “Exactly. That’s why you’re staying put, you horny little bastard.”
“So, you DON’T mind if I join you?” I asked, only half-joking.
Anastasia turned at the bathroom doorway, “Nooo, I mean, Yes, you’re NOT joining me” she said, drawing out the word with mock innocence. “You’ll just cause trouble.”
