BJKK-001 My sister has obscene breasts that are still developing and sensitive

On a thunderous summer evening, while Ayaka was in a daze from a summer cold, her brother raped her and poured his semen into her uterus, and she discovered the joys of being a woman. This controversial work features a sister with big, round eyes, beautiful black hair, a healthy, developing body trained through club activities, and large, obscene breasts that are obscenely large. A complete record of the forbidden, perverted impregnation sex with a sister who has just reached puberty and awakened to sex!
