A floating bra female teacher unconsciously seduces me

<2nd in the floating bra series!!> I have only one year left in my fun school life, and I'm practicing hard towards my last summer Inter-High School Championships, but recently I haven't been able to concentrate on my training at all. This is how we, Mr. Ayako, the advisor to our badminton club, are so defenseless that I can't believe the eye since the beginning of this year. Perhaps she doesn't even notice me as the opposite sex, but just leaning forward a little, she can see her bra...and even her nipples are completely visible. After all, I end up alone with Ayako-sensei, who is worried about me...
