This is a work where you experience kissing while being gently guided by your older sister Hikaru. She teaches you each movement with live commentary, like "It feels good when our lips press together" and "Bite my lower lip... suck it...", making her seem like a teacher. The viewer follows Hikaru's instructions, sucking and licking her tongue. You'll feel like you're learning through your body, thinking, "So there are this many variations to kissing." She continues kissing passionately while letting out cute breaths like "Mmm... nnnh...", and you can enjoy an intense French kiss that draws you in deeper and deeper as she gently leads you.
