This is a story about my colleague Karen, who sits next to me and is in the same area. Compared to the other employees, we got along well and we talked about anything, so when I confessed my feelings to her during overtime, I couldn't contain my sudden desire to have sex with her, so I started to flirt with her in the empty office and we ended up having sex. I was surprised at how big her bust was, in contrast to her slender body. Even though she said "no," her pussy was squishy and gave the OK sign, so I just inserted it. The contrast between her usual cheerful and efficient work ethic and the erotic girl in front of me was irresistible.
