This installment stars Kotomi Yuzuno, a gorgeous woman with a superbly slim figure. After hanging out at the home she shares with my best friend, I miss the last train and accept their offer to stay over. There are only two futons, so all three of us lie down together. My friend quickly falls asleep, but Kotomi starts moving beside me and whispers that she wants sex. I hesitate with him sleeping right there, until she suddenly kisses me and wraps her tongue around mine. My self-control disappears, and I eagerly fuck my best friend's girlfriend beside him, thrilled by the risk of being caught.
