I was seconded from the head office to a department that only has female employees. I got an erection when I saw Sasaki-san's panties showing through her pantyhose as she sat next to me with her plump thighs. When Sasaki noticed, she started to play with me for fun at first, but in reality, she was extremely excited by the erect penis of the only man there. She purposely stayed late to show me her panties in front of other employees, making me erect, and clenching her fist under the desk. In return, I touched her thighs through her pantyhose, and Sasaki had a sensitive reaction. I waited for the other employees to leave, then I wiggled my ass and pressed my erect penis against her pantyhose, unable to hold back any longer. I ripped her pantyhose and inserted myself inside her.
