Jiro received a call from Asia Aniki. When Asia Aniki calls, it's almost certainly about Natsumi-chan, who he's been obsessed with lately. As expected, the call was asking if Jiro wanted to come along since he was meeting Natsumi-chan. Apparently, Aniki has a secret plan this time. Jiro had rarely seen Aniki this fired up, as if he were plotting something. Seeing Aniki's unusual atmosphere today, Jiro started getting excited too. "Hello♡" Natsumi-chan, a gym trainer, has been accompanying them for nighttime strength training under the guise of work. Lately, Natsumi-chan has been the one making moves more often, and Jiro can't tell who is playing whom. "Are we training today too?♡" There she is, all excited with a cute smile. 【Yeah, maybe I'll be the one training Natsumi-chan today?】 "Eh?" Natsumi-chan is bewildered by this unprecedented turn of events. 【If you had to choose between S or M, which one do you think you are?】 "I think I'm half and half, but maybe leaning towards M..." 【Today, let's do some training to bring out your M side!】 As he says this, Aniki begins to undress Natsumi-chan from the black one-piece dress she's wearing. It seems the secret plan Aniki mentioned is soft SM play. Natsumi-chan's underwear today is red see-through lace, and it suits her perfectly. Her exposed stomach is toned, and the line of her waist is very beautiful.
