Sure. There was a bet between two friends about who could run a mile faster. One friend was so confident that he bet his favorite book. But he lost because he tripped during the run. Another one was about a bet on a football game result. A guy bet his new cap on the wrong team and lost it.
Here's another. Two colleagues bet on who could close the most sales in a month. The loser had to come to work dressed as a clown for a day. He showed up in a big red nose, floppy shoes and a colorful wig, making everyone in the office laugh.
There was a man who lost a bet with his wife. The bet was on who could save more money in a month. He thought he had it in the bag, but he ended up spending more on impulse buys. As a result, he had to take his wife on a romantic weekend getaway. It was an unexpected outcome for him, but it brought them closer together as they had a wonderful time on the trip.
Well, perhaps a man lost a bet to his wife about who could grow the nicest plant. He was so sure he could do it better with his 'dp' (which could stand for a special plant food or something). But in the end, he lost. As a result, he had to clean the garage which was full of old tools and junk. His wife supervised with a big smile on her face.
Let's say two friends made a bet on who could climb a tree faster. The one who lost the bet had to sing a silly song in front of all their neighbors. Another example might be a bet about who could memorize the most lines from a Shakespeare play. The loser then had to recite a really long and complicated monologue from the play in a park for everyone to hear, which was quite a comical sight.
There could be a bet where a guy loses and has to do all the household chores for a month. He might start off grumbling but in the end, he becomes really good at cleaning and cooking, which is a positive unexpected consequence.
Sure. There are stories where a lost bet might involve doing a good deed. Like if someone loses a bet, they have to volunteer at a local animal shelter for a day. It's a positive spin on the idea of a lost bet, without any sexual or inappropriate elements.
No. A lost bet sex story doesn't have to be inappropriate. It can be about humorous and innocent consequences of a bet. For example, a bet about who can run faster and the loser has to write a cheesy love poem to their best friend.
I don't think they are common. In today's world, we have laws and social norms that protect the rights of individuals, especially women. Betting on a person like that is not acceptable. However, in some old folktales or extreme historical cases, you might come across such stories.
