Teaching boys porn to jerk off.

I loved seeing a mans cock when I was a boy

Gotta LOVE the cock-bulge in his trousers. Then the rest follows.

How many boys need teaching?

For extra credit, please study this video which Darkvalor remembered well:

Lol pretty cool idea. Should turn this into an actual porn. I remember there was a porn movie where a teacher was teaching an all boys class about prostate orgasm. He demonstrated by asking a student as volunteer then fingered his ass while he got hard and came handsfree with the entire class watching.
