I fucked my sister under the pretext of a game

Hey, I’m Jake from Portland. My older sister, Sarah, is two years my senior, with a body that’s practically a perfect hourglass—curves in all the right places. I’d be lying if I said my friends didn’t notice her too; I’m pretty sure every guy in our circle has fantasized about her at some point.

One lazy summer afternoon, I couldn’t stop thinking about Sarah’s stunning figure, especially her perfectly rounded backside. Our parents were out visiting friends, leaving the house to just the two of us. I was lounging in my room, scheming about how to get closer to her, when an idea struck. I called out to her, “Hey, Sarah, come to my room! Let’s play a game!” She poked her head in, her long auburn hair falling over her shoulders, and gave me that playful smirk she’s known for. “What kind of game?” she asked, curious. “Let’s play keep-away with a ball,” I said, grabbing a small rubber ball from my desk. She couldn’t resist a challenge and agreed with a laugh.

I set the rules: “I’ll try to steal the ball from you, but you can’t let me have it.” She nodded, her eyes gleaming with mischief, and tucked the ball under her arm. She was wearing a tight pair of yoga pants and a cropped tank top that hugged her curves, making it hard to focus on anything but her. I moved behind her, pretending to reach for the ball, but my real goal was to press myself against her. As I leaned in, my body brushed against her backside, and I felt a rush as my arousal became impossible to hide. I started moving subtly, back and forth, testing her reaction. She didn’t pull away or say anything, so I got bolder, letting my hands graze her hips as I “tried” for the ball.

After a few minutes of this heated game, Sarah giggled and said, “Okay, let’s take a break.” We collapsed onto my bed, both of us catching our breath. I propped myself up on my elbow, my shoulder resting against her chest, her full breasts soft against me. She didn’t push me away. Instead, she turned to me, her eyes sparkling with curiosity. “Have you ever… you know, been with anyone?” she asked, her voice low. I shook my head, my heart pounding. “Nope. You?” She bit her lip, admitting she hadn’t either. The air between us crackled with tension, and I couldn’t hold back any longer.

I reached out, my hand finding her thigh, then sliding higher. Before I knew it, our lips crashed together in a hungry kiss. Her hand found me, stroking through my shorts, and I groaned into her mouth. I tugged at her tank top, pulling it over her head to reveal her perfect breasts, barely contained by a lacy pink bra. I kissed and sucked on them, losing myself in her softness. Then I slid her yoga pants down, revealing a matching pink thong. I pulled it aside and pressed myself against her, her warmth driving me wild. It was too much, and I finished quickly, overwhelmed by the moment.

But I wasn’t done. I kissed my way down her body, parting her thighs to taste her. She was already trembling, her breath hitching as I explored her with my tongue. Sarah moaned, her hands gripping my hair, urging me on. “Don’t stop,” she whispered, her voice desperate. She was lost in pleasure, and soon she was begging me to take her fully. “I want you to be my first,” she gasped, her words sending a jolt through me. I positioned myself carefully, easing into her. She winced as I broke through, a small amount of blood confirming her words. I paused, letting her adjust, then moved slowly, savoring the forbidden connection.

We moved to the bathroom to clean up, the steam from the shower adding to the haze of desire. Under the warm water, she dropped to her knees, taking me in her mouth with a skill that surprised me. I guided her, lost in the sensation, and soon finished again, this time with her eagerly accepting every drop. We weren’t done yet. I turned her around, the water cascading over us, and used some body oil from the shelf to ease my way. I entered her slowly from behind, her gasps mixing with the sound of the shower. It was intense, almost too much, but she urged me on, and we rode the wave of pleasure together.

Afterward, we collapsed on the bathroom floor, wrapped in towels, laughing and catching our breath. The game had turned into something neither of us expected, but the thrill of it lingered. Sarah leaned against me, her damp hair sticking to my shoulder, and whispered, “We’re keeping this our little secret, right?” I nodded, already dreaming of the next time we’d find ourselves alone, ready to explore the forbidden fantasies that now bound us closer than ever.
