The classmate I used to like was married, but they were in a sexless relationship and frustrated. After getting drunk and becoming vulnerable, I got excited seeing their panties peeking out from under their miniskirt. I secretly gripped my erect penis under the desk and was invited to the bathroom to have sex. A couple who had been spying on the scene could no longer hold back and had sex in the hallway. A woman whose husband was on a business trip invited the man who had sent her to her home for sex!
