In this work, Oishi Shinobu makes her AV debut. She looks great in a suit and is a clean-cut woman in her fifties. Unbeknownst to many, she is an active instructor at 'that' major cram school! Recently, due to massive layoffs, she lost her job, and as she turned fifty, she thought, 'I still don't want to give up on being a woman,' leading to her AV debut. Truly someone who teaches others. Such a refined atmosphere... A woman like this exposing her naked body and having sex in front of the camera! She presents intense intercourse that seems to appeal to the first cause of the cram school industry's recession—the low birth rate problem—and goes wild with it! When to do it? 'Now!'
