A young lady who is a teacher at a cram school. She speaks politely and exudes intelligence. Women who talk fast are great! First, I try to apply a huge electric massager to this serious-looking girl. At first, she avoids it with a smile, but gradually her face becomes serious, and before I know it, there is a serious stain in the center of her pants... After this, the busty masseuse and the male actor start a full-body erotic massage. As the massage gradually shifts from shiatsu on the back and waist to sticky erotic stimulation, she tries her best to smile and speak politely, but she twitches and loses her ability to speak. Although she is usually serious and strict, she is actually more sensitive than most people, and she arches her back and cums while dripping stringy juice... She is forced to suck the huge cock in front of her with her mouth full, and then it is inserted. The cram school teacher, who usually does not give off an erotic vibe, shows a completely different side to her, sticking out her tongue and screaming in ecstasy. This is a sudden transformation that is definitely in the top SS class, even among all the perverted girls out there in the world!
