[ Manga XXX ] Jitaku Keibiin 2

Kareki Tsunetaka has been a home-security officer for more than two decades. When his father remarries, his house is encroached upon by Katsuragi Shouko, a former widow with a physique too beautiful to be squandered by widowhood, who eventually moves in next door. After working as a home security officer, Tsunetaka has developed an intuitive sense that leads him to believe that Shouko intends to take over their family. Tsunetaka sets his eyes on Shouko's younger daughter, Yuki, in order to defend his family's house. He employs a variety of surveillance devices to gather information for blackmail purposes. Because he is always watching her, he gets a sight of her little but well-shaped breasts, unintentional glances at her inner thighs, and, most significantly, an intimate moment with her partner, which is all captured on tape. The home-security officer uses this blackmail material to lay waste to her virginity, blocking her impertinent lips with his rod and entering deep into her hitherto unexplored places with the help of the material. The next person on the list is... Yuki Katsuragi's sister!
