I'm friends with a kinky couple, Lars and Kristiina. They sometimes give me tasks. Per our agreement, I can't say no, but I can offer an alternative. So, when they told me to wear a butt plug to church on Sunday, I didn't want to do that. Instead, I offered my volunteer soup kitchen shift as an alternative. They agreed.

So, on a Sunday, they met me after church in a car. Kristiina was driving, and Lars was in the backseat, waiting for me. I was wearing black skirt that reached my knees, with a simple white blouse, and black flats.

I got into the car. Lars told me to spread my legs. He removed my panties and threw them on the floor of the car. He opened a bag and took out a small black butt plug. He told me to turn over and lean on the backseat with my legs spread apart.

He started to lube me up. His fingers were probing me. It wasn't long before he was pushing the butt plug inside me. I felt a tight, almost pinching feeling in my butt hole. Once the plug was all the way inside me, he gave me a couple of slaps on my ass. He did not allow me to put my panties on.

After the car ride, I walked into the soup kitchen. The butt plug was a little uncomfortable, and I could feel it rubbing against my ass as I walked. As I helped prepare food, I felt embarrassed by the plug inside me. Most of the people there were from my community, people I had known since childhood, and they knew me. I would look around, hoping no one would notice anything unusual about me. What if someone did notice something? What if the butt plug somehow slipped out? It was nerve-wrecking but I also loved the rush of excitement.

After several hours of standing up and bending over to help with the cooking, my hole was stretched out from the butt plug, and the soreness in my ass was intense.

Once my shift was over, Lars and Kristiina met me outside in the car. I got inside the car, and Lars helped me remove the plug. It felt so good to have it removed! I was relieved, and my anus was back to normal. Lars unbuckled his trousers, and I happily sucked his cock while Kristiina was driving me back to my place.
