MC is a normal guy that returned to his old town after years and enconutered a ex-delinquent famous to have been with at least 100 guys from some rumors.
She got married and her husband is now away for work, leaving she alone.
She invited MC to her house and procedeed right to doing sex, I'm guessing that she is now trying to be a good wife but her libido is still high, so to avoid rumors or a local talking she decided to fuck a timid looking guy she knew and that was only passing.
Now if she decided to stay married after that super fuck is another thing, this is not NTR, just classic cheating as we never see the husband nor is the guy brought up in some other way that makes he learn of the cheating.
