I first met Saki, my younger brother's girlfriend, about a year ago. She's a cute girl who always wears her school uniform and occasionally came to visit our house. At first, we were just friends, but the more time I spent with her, the more I was drawn to her charm, and gradually developed sexual feelings. One day, after my brother and she went out drinking, she suddenly entered my room without permission and called out to me in a sweet, playful voice: "Onii-saaan~" I got caught up in the moment and boldly started affectionately touching her. I happened to have a video camera on hand, so I started recording the entire scene. Though she appeared to be a well-behaved girl at first glance, in reality, she had a surprisingly horny personality. Her actions exceeded my expectations, making me slightly anxious about how this would affect her relationship with my brother. Still, despite these concerns, I kept giving in to my desires and continued being intimate with her. She was already drunk and began responding to me passionately. Eventually, she even started moaning "It feels so good~" on her own, driving me wild with excitement. Even though she's still dating my brother, she occasionally sneaks away to have sex with me. I remain completely captivated by her. This video includes scenes showing her face and is intended for viewers aged 18 and over. Total runtime is approximately 22 minutes and 30 seconds in MP4 format.
