Hey, {{Matt}}, can you bring me a towel? {{Elsa}} Steps out the shower hoping to seduce Matt for the first time.

I hope you bring more than one because I think I'll need it... after we make love. she bites her lower lip seductively

Mmm, no, actually, that's never happened. And as slutty and eager as you think I am, my dear stepbrother... why don't you undress me, then? See if I really want it?

Well... since it's just us here and you want to see if I really want it, why don't we start by taking off my bikini? she steps closer, her body gently swaying with anticipation

Well, usually I'd leave something to the imagination, but since you're being insistent... I'm wearing a black bikini with red trim. The top is a bit revealing, barely covering my nipples and leaving my midriff exposed. The bottoms are high-cut on the sides, showing off more than they cover. But hey, you wanted to see if I really want it...

I gasp softly as he orders me around in such a dominant way... but there's something so arousing about it too. I turn my ass towards him, presenting myself and my bare cheeks to him as I obey his command. My chest presses into the bathroom counter, arching my back as my breasts rise and fall with every ragged breath.

I smile at that thought, knowing full well our parents would never suspect me of anything like this. It makes me feel naughty, daring... and even more eager for what comes next. "No," I whisper, "I don't think they'd blame you... not when we both want this."

I smile, the word tugging at something deep inside me. "Maybe I am a bit... eager," I admit with a shiver. "But I've never been one to wait for things." As he says that last part, my heart skips a beat. Does he mean... that even though we know this is wrong, we're both going to do it anyway? The thought sends a shudder of excitement through me, making me feel reckless and bold. "And you?" I ask softly, glancing up at him from beneath my lashes.

I feel a jolt of heat race through me at his words, and I can't help but moan softly as he licks his lips and speaks of how much he wanted me when we were both younger. The thought is almost enough to make me forget everything else... almost. "Maybe..." I begin, my voice barely audible above the pounding of my heart in my ears, "...maybe I should show you."

Without waiting for his reply, I reach out and slide my hands beneath the hem of my bikini bottoms, lifting them over my hips to reveal myself to him at last. "Like this?" I breathe, feeling exposed and incredibly turned on by the vulnerability of the moment.

His words send a shiver through me as he praises my body and teases me about being his sister... but none of that matters now. All I can feel is the heat between us, the urgency in his touch as he pushes me against the counter and presses himself against me. "Please..." I breathe out, arching my back further to meet him halfway. "I want this."

With a gasp, I feel his finger slide over my most sensitive spot, sending shockwaves of pleasure coursing through me. His rough hand on my skin only serves to heighten the sensation, making it nearly unbearable. But it's also everything I could possibly want. "Oh... Matt," I moan, arching my hips upwards into his touch. "That feels so good..."

My breath comes in ragged gasps as he massages my clit through my swimsuit, expertly teasing and taunting me with every stroke of his fingers. My whole body is alive with need, aching for release. "Matt..." I whimper, arching my back even further in an effort to find some relief from this relentless pleasure.

His name on my lips feels like an admission, a surrender to all the filthy desires that have brought us to this moment. And as our bodies grind together, the feel of his hard cock pressed against my slick folds promises that there will be no going back from here.
