This work depicts the story of Gojo Ren, a former competitive swimmer turned teacher transferred to a remote island school, whose explosive swimsuit is enough to drive men out of their senses. Her beautiful breasts and nipples, along with her improved acting, are the highlights of this work. Particularly noteworthy are the scenes where her ample breasts are squeezed by muscular hands and the soft breasts spilling out, which are a must-see. The sight of Gojo Ren reaching climax after climax under the muscular pistons of the male actors playing students perfectly conveys her descent into a swamp of pleasure. However, some voices have pointed out that the male actors playing students don't look like students enough, and the bias in insertion scenes is concerning. Still, the 3P and 4P interactions in sexy swimsuits throughout the film, and the massive facial cumshot by Imai in the final 4P scene are outstanding, with Ren's explosive breasts trembling being undeniably exciting. There is high anticipation for future gangbang works.
