It's not because she's ugly, but because she's too beautiful for a married woman, and her husband often works overtime so he often comes home late.
Once when we were talking in the hallway, I learned that she also has a pretty high sex drive but her husband is weak so she has never been satisfied, she looked sad and talked a bit flirtatious with me, someone who still doesn't have a wife or girlfriend like me really likes to hear stories like that.
One fine day, she invited me over to her house to play and you guys know how it ended, I made her happy and I also shot my sperm all over her pussy.
