My voluptuous, busty girlfriend was NTR'd by my father and then subjected to a harem-style forced penetration. (Nami Nanami, DASS-947)

Nami and her boyfriend Naoya are living together with marriage in mind. One day, Naoya's father, taking advantage of a trip to Tokyo, comes to visit his son and decides to stay at their home for a week. Nami is understandably nervous facing her serious and old-fashioned father. To improve their relationship, Nami drinks with her father, but she gets too drunk and falls asleep in a compromising position, revealing her underwear. Her father, seeing the underwear, becomes excited and, unable to resist, uses an aphrodisiac, pinning Nami down and impregnating her in a stallion-like manner. Although Nami initially feels disgusted, she unknowingly becomes completely captivated by her father's hard penis.
