As my stepsister heads to the kitchen for a drink, I take advantage of being alone and pleasure myself - complete narrative

I was lounging on the couch, biding my time until my stepsister returned from her errands. The house was eerily quiet, a perfect opportunity for some alone time. Unable to resist the sudden surge of lust, I slipped my hand under my shirt, caressing my soft curves. The anticipation built up as I teased myself, my breath hitching with every stroke. Just as I was about to lose control, my stepsis walked in, interrupting my solo act. Startled, I quickly hid my hand, my face flushed with embarrassment. She noticed my disheveled state and playfully teased me, her eyes filled with mischief. Despite her teasing, she offered me a distraction that was too enticing to resist. We soon found ourselves in a passionate embrace, our bodies entwined in a heated dance. The intensity escalated, her moans echoing in the room as she rode me, her body quivering with pleasure. The climax was explosive, leaving us both breathless and satisfied.
