Hey, I need to get something off my chest—something that's been eating away at me since it happened. It's about this one time when Alex was away for work, and I found myself home alone... or so I thought.

I was feeling a bit restless, you know? There's this particular kind of loneliness that creeps in when he's gone, and I guess I was looking for a way to distract myself. I poured myself a glass of wine, kicked off my shoes, and let the silence of the apartment envelop me. It was weirdly liberating, the idea that I could do whatever I wanted without an audience.

One thing led to another, and there I was, stretched out on the couch in nothing but my silk robe, the one Alex loves. I let my hands wander, touching myself the way he does when we're together. It felt so good, so deliciously naughty, to be indulging like that in the middle of the day, with the sun streaming through the windows.

I was so caught up in the moment, lost in my own little world of pleasure, that I didn't hear the door open. It wasn't until Jenna gasped that I realized I wasn't alone. My eyes snapped open, and there she was, standing in the doorway, her expression a mix of shock and... well, something else. Something that made my heart race and my cheeks burn.

"Shit, Bella, I didn't mean to..." she trailed off, her gaze locked on where my hand was still tucked between my legs.

I was mortified, but there was this other part of me that felt a thrill at being caught, at being seen like that. "I thought you had class this afternoon," I managed to say, my voice barely above a whisper.

Jenna stepped inside, her eyes never leaving mine. "Class was canceled," she said softly. She took another step forward, and I could see the conflict in her eyes, the way her gaze kept flicking down to where I was still exposed.

I should have been embarrassed, should have stopped, but I didn't. Instead, I held her gaze, daring her to come closer, to cross that line with me. And she did. She closed the distance between us, her hands replacing mine, her touch both hesitant and confident.

It was electric, the feeling of her skin against mine. We didn't need words; our bodies did the talking. Her kiss was hungry, demanding, and I gave in to it completely, letting her explore me in ways I'd never imagined. It was a betrayal, sure, but in that moment, it felt so right, so inevitable.

We ended up on the floor, a tangle of limbs and whispered promises. It was raw and intense and over far too quickly. Afterward, we lay there in silence, both of us knowing that we'd crossed a boundary that could never be uncrossed.

I still think about that day, about the way Jenna looked at me, touched me. It's a secret I keep tucked away, a memory that flares to life when I'm alone in the dark. I've never told anyone about it, never breathed a word of what happened between us. But I needed to tell someone, to confess to this one indiscretion that's haunted me ever since.
