Kami Yuki, KAORI, Fuzuki Kaede...A new type of best for those who love butts, featuring only T-BACK that snugly and snuggle into their superb beautiful butts! This includes a lot of plays that can only be played with T-BACK, where a vibrator is thrust into the anus that peers from the side, and a cock is inserted by shifting it to the side. It's a 8-hour period with a lot of charm from T-BACK, which is more lewd than not wearing it!
