Hana Aoyama is shaken when her husband's adult younger brother suddenly admits he is a virgin and asks her to initiate him into sex. He strips without warning and thrusts his hard young cock in front of her, weakening her resolve. She makes him promise never to tell her husband, but licking his swollen tip leaves her underwear secretly soaked. When he suddenly shoots youthful cum into her mouth, her restraint collapses and she surrenders to whatever her brother-in-law wants. His hip work is far too skilled for a virgin, making her convulse through repeated orgasms. His cock recovers no matter how many times he cums, leaving Hana utterly exhausted.
