LF Doujin: Wife gets brainwashed by video delivery and ends up joining a cult in the end

I read this hentai around 2-3y ago, here's the plot: The hentai manga starts with a wife getting unsolicited delivery by a delivery man wearing a cap (I believe the delivery guy wearing the cap is also the first page) The delivery contains a video tape, the wife plays it and turns out it's some adult video, at first nothing happens but the more she watches the Hornier she gets and she's getting brainwashed and starts masturbating. More deliveries come by and they get increasingly bolder, from video to different sorts of sex toys

At the end of the manga the wife is completely brainwashed and is invited to a cult, the cult is infact behind all this and they brainwash wives to fuck them, she accepts her fate and gets fucked by the cult members. Please help me find this one
