I have a different type of experience. When I was sec 3, during the era of blue tapes (yes, blue tapes... before vcds and dvds), I was caught passing a tape to a classmate in class. The tape was unmarked as usual. A female english teacher caught me passing it. From our reaction, I guessed she knew it was porn, although we denied it by saying it's a recording of the previous night's drama serial.
The same english teacher called me to see her after school in class (1 to 1) and asked me if it's porn. After several denials, she asked me point blank if I could get her some porn tapes as she will like to watch with her husband!

Wah lan... I was wondering if it is a trick question. But as it's after school and I'm damn sure my friend has left school with the porn tape, I told her I know how to get her some. I then asked her what kind she likes... She told me Ang Mo. I asked what kind of storyline she likes... She looked at me with big big eyes and asked 'Huh? Got story one ah?'. I replied 'Got... got vampire, got school stuff, office, modelling....' She began to think and I stood there looking at her face... Wah lan... dunno how to describe. I never thought I got a chance to talk sex with teacher...
End up I passed her my 2 favourite Ang Moh tapes with different story line. After 1 week, she still hasn't returned to me. Wondering why she hold on my favourite tapes, I approached her. She told me she liked them a lot and she wants to keep them! I told them those are my favourite and I dun want to lose them. She insists on keeping them and paid me $10 per tape. Sian man... I got to call those numbers that are posted in my mail box and meeting the porn runner at some void deck again...
