A classmate I used to like is married, but sexless and frustrated. She gets drunk and defenseless, and I get excited when I see her panties under her miniskirt. She secretly grabs my erect penis under the desk and invites me to the bathroom for sex. A man and woman who were watching the scene can't resist and end up having sex in the hallway. A girl whose husband is on a business trip invites a man who gave her a ride home to her house for sex!
