Hot Stepsister Gets Orgasm after School in the Sun

After school, the sun was still high and hot, perfect for some after-school fun. Our innocent step-sister, with her luscious big breasts and that schoolgirl look, couldn't resist the urge to spend some alone time with herself. She found her way to her room, locked the door, and let the tension build. Her uniform was already half off, revealing her curves and the promise of what was to come. She lay back on her bed, her breath quickening as she imagined her stepsister's touch. Her hands started to explore her body, her fingers tracing the curves of her big tits. She pinched her nipples, her body arching with pleasure. Her hands moved lower, under her skirt, her fingers teasing her wet pussy. She rubbed herself, her body trembling with desire. Her fingers worked faster, her breath coming in short gasps. She rubbed her clit, her body shaking with pleasure. Her orgasm hit her hard, her body convulsing as waves of pleasure washed over her. She screamed her pleasure, her body shaking with the force of her climax. She lay there, her body spent, a satisfied smile on her face. The sun shone through the window, casting a warm glow over her spent body. This was her secret, her after-school treat, her orgasm in the sun.
