My recently debuted gyaru sister chose me, her older brother, for sex practice. Two inexperienced people out of control with intense thrusting. Sumire Kuramoto
Since my sister decided to become a gyaru, she figured she had to date flashy guys. So she decided to practice sex—with me, her older brother! I've watched plenty of AVs, but I've never done it for real. Still, if I can't perform when the time comes, it'll be embarrassing, and I've got my pride as an older brother to uphold. That's how my sister and I started piston practice together. Maybe because we're siblings, our chemistry is incredible. Looks like my stamina was inherited too. We keep going without even realizing we've both climaxed, reversing thrusts in a wild double runaway rhythm, shooting load after load deep inside her!
