A classmate I admired came to the reunion. She was married but frustrated because she didn't have sex with her husband. She flashed her panties and breasts in front of me, a perennial single man, and while holding my erect dick so that no one would notice, she whispered in my ear, "Let's do it in the store." When we were alone in the bathroom or a secluded hallway, she was full of sexual desire and wanted my dick, so we had sex.
