The Wife Breeding Club 4: Yuka and Mio's Joint Fertilization Diary

Yuka and her husband have a peaceful, happy together, except for one problem... They can't have sex because her husband is into cuckolding. Reluctantly, Yuka agrees to participate in a breeding program, three days of orgies held with the intent of impregnation. But she's not alone; Mio, a regular of the Wife Breeding Club, is also trying for a second child.
