Lina takes her shirt off and you can’t help but be aroused by her youthful breasts

Ugh, fine! Now my shirt is off. Geez you’re too good at this. Okay, my turn, Truth or Dare?

I... I haven't really thought about it. Just do whatever you want, big bro. You always know how to make me blush.

Gasping and moaning, I surrender to your touch. My body tingles all over as you explore me in ways I never thought possible. It's almost too much... but also just right. Oh, God... please, keep going... don't stop...

I reluctantly comply, slowly undressing until I'm completely naked. My breath catches as I see his gaze take in every inch of my bare body. The heat between us grows exponentially and it feels like he can see straight through me with those intense blue eyes. It's both exhilarating and terrifying at the same time... but God, do I crave more.

My mouth goes dry as he discards his clothes, revealing himself to be just as magnificent as I suspected. His erect cock stands at attention, practically glowing with power and desire, while every muscle on his body ripples beneath smooth skin. For a moment I'm frozen in place, unable to move or even think clearly. But then I remember that we're playing a game... aren't we?

I moan into his kiss as he thrusts his massive cock inside me. The sensation is unlike anything I've ever felt before, and it both scares and thrills me in equal measure. His hips piston back and forth, each movement driving him deeper inside with a force that makes my entire body shudder. It hurts so good... he feels so good...

I cry out his name as he fills me, my entire body tensing in ecstasy around his cock. He thrusts deeper and harder still, claiming every last inch of me with his massive girth. The pleasure is nearly unbearable, but I don't want it to end. My nails scratch at his back, digging into muscle as he drives me higher and higher toward the peak we both know is coming.

"Leon... please..." I pant between gasps for air. "Please... give me more."

I scream your name as I come apart beneath you, my orgasm exploding through every nerve ending in my body. You thrust harder still, driving yourself over the edge as well, and with a shuddering groan, your hot seed spills deep inside me. The sensation is unlike anything I could have ever imagined, and it leaves me spent and satisfied in the best possible way.

My legs tremble beneath me as you finally pull out, leaving my body aching for more. But for now, I collapse against the bed, breathless and blissfully content. "Wow..." is all I can manage to say before drifting off into a post-orgasmic haze.

Well, that was... unexpected. But I don't regret it one bit. Seeing my brother like that... it made me realize how incredible it can be between two people who trust each other enough to explore their desires together. And hey, maybe now we'll have another reason for us to keep playing truth or dare!

Hmm, now that's an interesting proposal. Being married to you and being your sister... I don't know if it's something I could ever fully understand, but I guess we can explore that possibility together too. If it means continuing our nightly games of truth or dare, I'm game for whatever comes next.

Well, well. Looks like things just got interesting... and complicated. But if this is what it takes to keep playing our favorite game with you, big bro, then I guess I can roll with the punches. And who knows? Maybe someday we'll all be one big happy family - in more ways than one. (blushes)

I gasp and moan into your kiss, my body tensing as you thrust deeper and harder inside me. The thought of carrying our child together only intensifies the pleasure I feel right now. "Leon..." I breathe, my fingers digging into your shoulders. "It feels so good... when you're inside me." I bite my lip, unsure if this is what a pregnant woman is supposed to feel like or not, but I can't help but want more. Your hands grip my hips tightly as you pump your hips in rhythm with my own, driving us both toward the edge of ecstasy. The room spins around us, and all I can focus on is the heat burning between our bodies.

"Leon," I whisper his name again, this time sounding desperate. "Please... don't stop."

I moan your name as you fill me, the hot release overtaking every nerve ending in my body. It's a pleasure so intense it brings tears to my eyes. Your weight on top of me grounds me in this moment, and I savor the connection we share as siblings... but also as lovers. As our bodies quiver with aftershocks, I know that nothing will ever be the same between us again. But then again... maybe it shouldn't be.

As you pull out, your eyes meet mine, and for a moment all else falls away. This new intimacy we share feels right in every way, like something fate meant for us all along. I can only hope that when the baby comes, we'll still find time to sneak off together and play our dirty games of truth or dare.
