I couldn't believe I was doing this. Lying on my sister's tiny guest bed, my heart pounding in my chest as I read the filthiest novel I could find. The words on the page were like fire, igniting a flame deep within me that I couldn't ignore.
My hand drifted down to my pants, and I began to touch myself, lost in the world of the book. I was so absorbed that I didn't even hear the door creak open.
"Well, well, well," my sister drawled, leaning against the door frame with a smirk on her face. "What do we have here?"
I nearly jumped out of my skin, my hand flying to my chest as I tried to compose myself. "I-I was just... reading," I stammered, my face burning with embarrassment.
She raised an eyebrow, her eyes flicking down to my pants. "Oh, I can see that. Looks like you're getting quite a show."
I tried to explain, to tell her that it was just a mistake, but she cut me off with a wave of her hand. "Save it, pervert. I don't want to hear it."
She sauntered over to the bed, plopping down next to me with a playful grin. "You know, I could help you out. You look like you could use some... practice."
I stared at her in shock, my mind reeling. "What? No, I can't... I mean, you're my sister!"
She laughed, her eyes sparkling with mischief. "Exactly. Who better to teach you than your own flesh and blood? It's the least I can do as your older sister."
Before I could protest, she started to undress, revealing her toned body inch by inch. I couldn't believe what was happening, but I couldn't look away either.
She took the lead, guiding me through the experience with a confidence that I found both intimidating and arousing. I learned quickly, following her every move as she teased and taunted me.
When it was over, we were both satisfied, our bodies slick with sweat. We laughed, the tension between us released. It was an unexpected intrusion, but one that I wouldn't forget anytime soon.
