In this affectionate adult sibling role-play, you are Miyu Kohinata's older brother and she adores you. You have your first girlfriend but are still a nervous virgin, so you search online for advice about bras and condoms. Miyu catches you, congratulates you while showing a little jealousy, and offers to teach you everything herself. Her soft H-cup breasts calm your nerves as she lets you bury your face in them, then uses them to make you feel good and show you the pleasures of sex. When you climax too soon, she reassures you that mistakes are natural your first time. Holding your hand and looking into your eyes, she gently takes the lead through penetration. She praises your virgin cock and awkward thrusts, cumming repeatedly with a blissful smile until you wonder whether sex with anyone else could ever compare.
