This time, a special project that develops Mao Watanabe's nipples like a highly sensitive genitalia! Pinch it with your fingers and play it and turn it with your fingers and the stimulation of the rotor will start to react with Bikunbikun. In addition, there are plenty of thoughtful nipple tortures such as "Blindfold restraint toy torture", "Swimming swimsuit lotion SEX", and "Nipple kneading continuous SEX"! Only for the distribution limited edition, a special recording of a making video where you can see a cute face full of smiles!
