The work I checked this time is 'Nipple-focused Packed Train!', featuring Risa Kisaragi. This work thoroughly teases the nipples, making it a must-see for breast lovers. Starting with the molestation scene inside the train, the nipples, whose sensitivity is heightened to the limit by soft touches, are practically clitoralized. The ultra-close-up shots allow for a detailed observation of the erect, firm nipples. Risa Kisaragi's acting, her large breasts, and her climax performances shine. Especially, the scenes from naked sex in the hotel to threesomes and chest shots are right on target. However, the common angles from below and the use of toys in train molestation works felt unnecessary to me personally. More frontal and overall depictions would have made it even more enjoyable.
