You should firmly stop them and let them know that this is not acceptable behavior. Pedophilia - related content is illegal and unethical.
Tell them that such stories are a form of abuse and harm to children. Encourage them to focus on positive and healthy topics instead. For example, talk about great achievements in art, science or sports.
If they continue, it may be necessary to report them to the appropriate authorities. We all have a responsibility to protect children and keep our society safe from any form of pedophilic behavior or promotion.
If the 'little ped stories' are about little pedestrians, we can learn about safety. For instance, how to cross the road properly, look both ways, and be aware of traffic signals.
We should focus on positive, clean and educational stories rather than 'dirty little stories'. There are so many great stories out there about friendship, kindness and achievement.
I'm not sure what specific 'little ped stories' you mean. It could be about little adventures of a ped (a person in some context, like a pedestrian perhaps). For example, a little ped's story could be about their daily walk to school and the interesting things they see along the way, like a friendly dog or a beautiful flower garden.
Politely stop them. Just say that this is an inappropriate topic and you don't want to hear it.
Politely tell them that you are not interested in hearing such personal stories. You can say something like 'I'm sorry, but I don't think it's appropriate to discuss this.'

You should firmly stop them. Let them know that this is inappropriate behavior. You can also distance yourself from such people who lack respect for others' privacy.
Tell them that it is unethical and disrespectful behavior. Encourage them to respect their partner's privacy and the boundaries of their relationship. If they continue, you may need to distance yourself from them as they are showing a lack of respect for their partner and proper social norms.
Sharing dirty stories is not appropriate. However, I can share some funny little clean stories. For example, once there was a little squirrel that tried to hide its nuts in a gardener's hat by mistake. The gardener was so surprised when he put on his hat and felt all those lumpy nuts!
If someone tries to share such stories, you can express your discomfort. You could say, 'I'm really not comfortable with this. We should respect the privacy of our friend's family. There are so many other things we can talk about, like how our friend is doing in general or their recent achievements.' This way, you make it clear that such inappropriate sharing is not acceptable while also guiding the conversation in a better direction.
