"Are you nervous?" she asks, but I'm too tense to answer. Seeing this, Keito-chan gently guides me, saying, "Nibble on my lips?" She has a slightly M-like vibe, but in reality, she's an older sister who firmly leads the way—that gap is irresistible. Moreover, she boldly moves her thick tongue, licking and sucking. Her kisses, more aggressive than her appearance suggests, gradually captivate me. Though she wraps me in tenderness, the kisses are far more intense than I imagined, and before I know it, I'm completely caught up in Keito-chan's pace.
