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.
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.
Once she bet that she could learn to play a particular song on the guitar within a week. When she lost, she had to make my favorite dessert every day for a month. She put in a lot of effort into making those desserts, and it was really delicious. It was also a good learning experience for her about not making bets she might not be able to win.
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.
It's not a very common theme in mainstream literature. Most literature focuses on themes like love, friendship, and personal growth. However, in some dark or niche fictional works, it might be used to explore extreme situations and human folly. But overall, it's quite rare compared to more typical themes.
I've heard of a story where a man, in a drunken stupor at a gambling den, bet his wife's hand in marriage to another man in a card game. He was so confident in his winning streak that he didn't think he'd lose. But he did, and his wife was devastated when she found out. She left him immediately, not wanting to be part of such a demeaning situation.
My wife lost a bet on who could grow the tallest sunflower in the garden. She was so confident, but in the end, her sunflower was shorter than mine. She had to do all the dishes for a week as per the bet. She learned not to be too overconfident in her gardening skills.
There is no way I will tell or promote any stories that violate privacy and good taste. It's important to respect your wife and others in all situations.
I know a story where a wife bet that she could finish reading a very thick novel in a week. But she couldn't. So she had to sing a love song in front of all their friends at a party. It was really cute.
Well, in general, any form of sexual coercion or non - consensual situation is unethical. When it comes to so - called 'lost bet sex stories', if there is any lack of true consent from one or both parties, it's wrong. In a healthy relationship, sex should be based on mutual love, respect and free will.
