MKON-115 My girlfriend who came with me to the massage parlor said 'Big boobs cause shoulder stiffness,' so we decided to get treated together... I heard moaning from the other side of a curtain... Hatsuki no Ao

The main character, Yusuke, has been stiff recently, and when he tells Noo that he's going for chiropractic treatment, he says, "That looks interesting. Can I follow me too?" and ends up following him.Yusuke goes to a chiropractic clinic together and checks in.However, the chiropractor also said, "My girlfriend might be more severe," and "In many cases, people with larger busts become more severe without realizing it," and Noo also got treatment.From across from the curtains I heard Noa say, "Ohhhh!? Ohhhhh!?!? Ohhhhhhhhh!?!?"What kind of treatment are you receiving??
