I don't think they are overly common. Most wives are committed to their marriages. But it can happen in some cases where there are problems in the relationship at home. For example, if a wife is unhappy with her husband, she might be more vulnerable to the attention of a guy in a bar.
No. Such a story involves inappropriate and unethical behavior. In society, we uphold values that promote healthy, consensual and respectful relationships, and this kind of description goes against these basic values.

The phrase 'harry potter sucks dick' is a very vulgar and inappropriate expression that shows disrespect to the 'Harry Potter' franchise. 'Fanfic' stands for fan fiction.

One story could be that a wife who was feeling neglected at home went to a bar. There, she met a guy who seemed really interested in her. They started talking and she ended up sharing all her problems with him. Eventually, she got so caught up in the attention that she started to rely on his company more and more, which put a strain on her marriage. It was like she was being'sucked' into this new relationship in the bar setting.
