In his Master's project, Bob interviewed hundreds of couples. In the process he often found out personal information about a couple. Such as the fact that Ralph and Tanya wanted a baby as much as it was possible to want a baby. But an accident had left Ralph unable to father a child. It had the potential to destroy their marriage.

They couldn't afford in vitro fertilization. They didn't want to ask one of their male friends to "help out".

But Bob wasn't a "friend." Not in the sense that it would be weird to ask for a favor like that.

So they did.

And things got very weird after all.

In the end, several questions were raised.

1. Is it cheating if the husband agrees she can have sex with another man?
2. Is it cheating if she tries not to enjoy it and fails?
3. And is it possible for cheating to actually help a couple's marriage get stronger?

Ralph and Tanya found out the answers. And Bob put them in his paper.
