My stepsister, Anna, had been teasing me relentlessly since she moved in. One night, after her boyfriend had left, she entered my room wearing only a sheer robe. Her body glistening with perspiration from their previous encounter. She sat on my bed, her legs spread ever so slightly, and began to undo the sash of her robe.
As she slowly slid it off her body, revealing her glistening curves underneath, I couldn't help but feel aroused. My heart raced, and I couldn't speak. "You've been such a good brother," she purred, crawling towards me on all fours. "It's only fair that I thank you properly."
With each step, she brushed against my thighs, sending waves of desire coursing through my veins. I couldn't believe this was happening, but I didn t still managed to find the strength within me to overcome the situation.
