Making her choose to do things, like the old guy did, he made her choose to cover him and overtime she can get used to it, thus they can push the boundaries. I'm not saying it's a real portrayal (although claiming that attractive people don't cheat with less attractive or downright ugly people is also not true), it's all running on porn logic.How does groping/awkward situations equal corruption enough to make her a slut? Is she mentally retarded? Just shut your brain off for ntr unless the dudes look like Brad Pitt it will not make sense.
