When I went to a newly-opened cafe, I was taken to a private room and serviced sexually?! The main character's name is Yuichi Aikawa. He spends most of his days going to class and working a part-time job. One day, on his way back home from work, he receives a flier about a newly-opened cafe. He decided to go to the cafe since he received a discount coupon, assuming it would be a normal cafe. However, when he gets there they take him to a private room and a worker named Reina serves him a cup of tea with her mouth. This eventually escalates and they end up having sex, their passionate noises echoing throughout the room. Yuichi initially found this odd, but knew he wanted this service again while thrusting himself into Reina.
