As usual, my brother and his girlfriend Mitsuki were having sex in a darkened room. I secretly watched them from the shadows. For a virgin like me, witnessing their intercourse was an intense thrill, and right there, I dropped to my knees in dogeza, begging my brother to let me borrow Mitsuki's pussy. Reluctantly agreeing, my brother guided my huge cock into her, and Mitsuki instantly became aroused. Fueled by overwhelming excitement, I pounded her mercilessly, and ultimately ended up giving my brother's girlfriend a creampie.
