A classmate I used to like is married, but I'm 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. The man and woman who were watching the scene can't hold back and end up fucking in the hallway. A girl whose husband is away on a business trip invites a guy home to have sex with her!
