Ok, from Lessons 1 to 3 started from braless, to showing pokies, then going transparent. By now, teacher already saw her full view, 2 nn. So we decided to tone down a bit otherwise it would be overboard. How come every class, his student dress like that, letting him see her nn. He might think its purposely done. He has been professional. No advances, no flirtations. He only look, but that also try not to get caught.
So for lesson 4,
She wore a cotton tshirt. Only can see her puffy nipples pushing out, only very slightly translucent.
Lesson 5
Toned down some more. Loose blouse, but cannot see anything at all. This lesson more decent.
Lesson 6
Wore the same as lesson 4.
Lesson 7 to 8
Nothing to see at all. Only can see shes braless something he already knows.
After cooling the temperature for a while, then it was time to do showoff again in the next lesson. In lesson 8, we would change the setup.
