My (M18) tution teacher (F27) is interested in me [mf]

So, I go to my neighbour lady who takes tution classes for board exams since I was weak in few subjects. Her behaviour was kinda okay for 3 years. 5 minths back she started getting physically closer to me.

She said that I could sit on her lap since we were freinds and I used to sit. But I was scared as to how she would react if I touched her boobs if I bent back. But she used to say tjat I could bend and sit, but I could not.

Yesterday, she was changing her salwar in the other room, but I could see her through the crack of door. Yesterday, she did not wear pants but just the top and took lessons for me.
