Ayumi and Erica sisters who live next to each other in the condominium and are still close to each other after getting married. Ayumi said she wanted to divorce her husband, Tetsuya, and live with Erica, although she wasn't close to her sisters. One day ... Tetsuya, who wanted a child, had Ayumi inserted a raw cock and had a vaginal cum shot. "If you have this boy's companion, you will not be able to divorce !!" Erica came to the bedroom just before the sperm implanted in Ayumi's Ma Ko.
