As a college student living in the city, I had left my family home to live alone, completely absorbed in the many urban pleasures and nightlife. During one unexpected long weekend, my younger sister suddenly showed up, catching me completely off guard. She had come out of concern. Confessing, "I'm going to enroll in the same university as you," she expressed her desire to live together. Her words stirred unfamiliar emotions within me—beyond mere sibling affection, I began to feel romantic desire. She suddenly kissed me. That long-awaited kiss made me see her not just as a sister, but from a completely different perspective. From that moment on, our relationship rapidly escalated. She obediently follows my command to lick every inch of my sweat-covered body. "Ew! You're so dirty... but if it makes you love me, then I'll do my best!" she says, responding with surprising enthusiasm. Her pure devotion only fuels my arousal further. Ears, nipples, abdomen, navel, sweaty groin, thighs, calves, soles of my feet—she meticulously licks every drop of sweat from my body, her actions resembling a work of art. I make her suck my cock, long untouched by masturbation, and enjoy deep-throating her. I cum heavily inside her struggling mouth, then force her to swallow every drop. A virgin with no experience, I make her spread her pussy and instruct her to insert my cock herself. "What should I do? I'm scared... so scared..." she trembles, but slowly, my cock penetrates her tight virgin pussy. Driven by pure lust, I thrust into her violently. "You're putting sperm inside my pussy? Huh? Is that okay?" she asks anxiously, but without explanation, I forcefully creampie her. [Binaural Recording 3D HQ High-Quality VR]
