"Sushi sounds amazing!" Sarah exclaims, her eyes lighting up at the mention of food. "I haven't had it in forever! That'd be so much fun." She glances over at Kayla again, hoping that she'll agree to go along with this plan.

"So," she continues, looking back at Adam, "what time are you thinking?"

Sarah grins at the suggestive squeeze, feeling a shiver of pleasure run down her spine. "Perfect," she says with a nod. "I'll get changed in the meantime." With one last teasing wink for Adam, Sarah excuses herself and heads off to her room.

As she disappears down the hallway, she can't help but feel a thrill of excitement running through her. Not only has she managed to keep this secret from her sister...

Sarah moans and gasps, her body tensing and relaxing with each thrust as she feels you filling her up. Her fingers dig into the bed sheets, her nails leaving crescent-shaped impressions in the fabric. "Oh god," she whispers, "I've never... I mean..." She trails off, unable to find the words to express how it feels to have you so deep inside her. Her hips buck upward, meeting your thrusts with equal force, her ass clapping against your groin with each impact.

Sarah bites her lip, her eyes half-lidded with pleasure as she feels you thrust deeper and harder into her ass. "I... we..." She pants, struggling to catch her breath between words. Her fingers curl into fists, nails digging into the sheets as she arches her back, pushing back against you in rhythm with your thrusts.

"Oh god," she moans, "I can't... I need more..."

Oh, don't worry about that!" Sarah giggles, her breath hot against your neck. "I've been with plenty of guys before...and I know how to take care of myself." She leans in closer, nibbling on your earlobe as she teases, "Besides, it would be our little secret, wouldn't it?"

Her hand moves between your legs again, this time rubbing circles over your sensitive flesh. "And think about how much fun we could have," she whispers, her voice thick with desire. "

Oh fuck yes! Sarah gasps as you fill her up again, her body shuddering with pleasure beneath you. Her eyes roll back in her head and she lets out a loud moan, arching her back as the sensation washes over her. She grinds against you, desperate for more of your cock inside her.

"Fuck me hard, Adam!" she cries out, her voice hoarse from desire. "I want to feel every inch of you!"

As you push your cock inside me with one final, powerful thrust and fill me completely, my world explodes in a cascade of pleasure. I can feel every muscle in my body tense as waves of ecstasy wash over me, leaving me panting for breath. You hold yourself deep inside me, refusing to let go as the last shudders pass through my body.

Eventually, you pull out slowly, watching as your seed oozes from my opening.

Your seed feels hot inside me, a reminder of the passion we just shared. I wonder if my husband would ever be able to make me feel like this...I doubt it. This was meant to be our secret, something between us sisters, but now that I know what it's like...how good you are at making love...I don't want to give it up.

I roll over and nestle against your chest, my breath still ragged from the intense orgasm. You wrap your arms around me protectively, holding me close.

Kayla watches as your wife closes her eyes, taking a deep breath before opening them again and looking at Kayla. There's a flicker of something in her gaze...hope, maybe? Or curiosity? It's hard to tell. "We could... try," she finally says, nodding slowly. "But we need to be careful."

Her fingers move closer together, lacing through Kayla's and pressing their palms against each other.

Kayla smiles gently at your wife, feeling a wave of relief wash over her at the acknowledgement of their connection. "Of course," she says softly, mirroring your wife's slow nod. "We can take it slow...figure things out together."

Her fingers move in small circles against yours, her touch light and reassuring as they explore the contact between them. "Whatever happens...we'll face it together," she whispers, looking into your eyes as she speaks the words.
