A colleague who shares the same work area and sits right next to me—Karen. We were exceptionally close compared to other coworkers, able to talk about anything. When I confessed my feelings to her during overtime, I suddenly felt an overwhelming urge: "I want to have sex!" With no one else around in the office, I began seducing her, and we ended up having sex. Despite her slender frame, she surprisingly had big tits, which shocked me. She kept saying "No, this is wrong," but her pussy was already wet and slippery, clearly giving me the green light, so I went ahead and thrust inside. The contrast between her usual bright, efficient office lady self and the horny woman right in front of me was so intense that I couldn't help but sigh in awe.
