[Fuyuno Mikan] My Newly Met Little Sister Milks Me Dry Every Night! (COMIC LO 2023-02) [Team Rabu2]

When his father remarries, a young man suddenly gains a little step-sister who wastes no time shoving his face into her soft, undeveloped chest—and she has zero intention of letting him escape. With her mother cheerfully telling her to squeeze everything she can and the parents gone for three days, the shameless girl demands he lick and grope her tiny breasts before climbing on top for condom-wrapped round after round. By the end of the third day she's cheerfully counting her tenth climax of the day and still angling for one final ride before Mom and Dad walk back through the door.
