Spanked by my sister during a study group
Our college sent us all home in the spring semester because of the virus, and my older sister lived closer to the school than my parents so I went to live with her. Our classes were online so I spent most of the day in front of the computer with a streaming thing going on. Despite her reminding me to pick up my dishes and put them in the dishwasher (among other reasonable requests) I used my classes as an excuse for why I was too busy.
She got fed up a few months in and told me that I was acting like a spoiled brat. "Do you remember what happened when we misbehaved as kids?" she'd ask. Of course the answer was that mom would spank us, but I pretended not to remember. She sat down and pulled me over her lap. I was caught off guard and before I knew what was happening, she had my sweats down and was working on my underwear.
It was in between classes and I was having a study group sort of things with some friends. The camera wasn't pointed right at the sofa but the microphone picked up the rather brief spanking that followed. I wasn 't aware of it though. When I git back to the computer, one of the girls in the group asked me if I had picked up my dishes, then laughed. I knew then that they had heard the whole thing!
After the semester ended I hoped the joking would end too, but now two of the girls are texting me, asking me if I'm being a good boy.
