In a dark, narrow private room where a man and a woman can be alone, at an 'oppabu' where the girl sits on the customer's lap and massages his chest, enjoy the plump, beautiful breasts of Sayumi-chan, a stunningly cute and perverted oppabu girl belonging to this shop, while secretly having live insertion so as not to be noticed by the shop! Furthermore, take her out of the shop and have live sex! The subjective video also adds to the great satisfaction!
