Forum: Story Recommendations

Hi everybody.

I'm looking for stories where the MC or his/her spouse are bound by some kind of agreement/pact to have sex with somebody else.

For example, his wife suddenly tells him that she is going to have sex with some guy because she made a pact with her college sorority sisters years ago. Or she receives a letter reminding her of some oath with a club/church/lodge, or something like that.

Are there any stories like this?

Thanks in advance.

Lazlo's story Pfand X comes to mind.

Description: It is a harsh cruel world in which danger lurks for the unwary. After a small town is wiped out, ten families sign the Pfand X, the pledge of ten, in which they promise to support and help each other in good times and bad. After 18 generations, the families of the Pfand X are once again threatened.

The Agreement by Don Lockwood

Note: includes incest and sex between adults and teenagers.

Thanks!
