NGHJ-059 Hikari Misaki, Sayu Nanahara

A sister with pre-wedding jitters and her virgin brother take a family bath together for the first time in over 10 years lol. "There's no way I'd get turned on by my sister's boobs," he tries to act tough, but as they wash each other with bubbles, his sister pulls back his foreskin, causing him to get a rock-hard erection and revealing his virginity... Even though his sister has a fiancé, she awakens her own lust as her brother's huge cock explodes with rock-hard erection // "It's okay if I'm your first, right...?" A celebratory brother-sister first time having unprotected sex and cumming inside.
