I'll do my best for the team members! The sincere feelings of the female manager sometimes cause the male team members to get an erection. The overly careful massage of the lower body by the female manager especially stimulates the erotic Kokoro of the boys and makes them get an instant erection. However, the female manager has a puzzled look on her face, not knowing why they are getting an erection. It is a sin for the female manager to make them get excited even though they don't want to!
