Recently, my wife has been on a diet again, and it seems like she's addicted to watching some videos. It turns out that she's afraid of gaining weight, so she started watching and following the instructions of a fitness trainer in a weight loss exercise video. The trainer is Hibiki, a person with a perfect body and a beautiful face. It seems like her class is accepting new students, so my wife invited me to join. Hibiki guides me in a friendly and polite manner, but for some reason, the distance between us keeps getting shorter! As instructing both of us at the same time doesn't seem effective, Hibiki suggests teaching each of us separately, and I think that's a good idea, so I agree. The next day, Hibiki still focuses on guiding me in the workout, but she seems to touch me more, constantly revealing her cleavage as if inviting me. And she seduces me! I keep refusing because I already have a wife, but Hibiki's seduction is something no man can resist! After a while, my body becomes firmer and more robust, and I'm not sure if it's the result of the hard workout exercises or the endless lovemaking sessions between me and the female trainer...
