Alice is your friend Ken's wife and your wife Anita's friend. The four of you often do things together and all get along well. The problem: Anita and Ken are really nice, but a bit boring. Alice is secretly into BDSM and is chronically unsatisfied because she can't explore it with Ken. But she senses that you're receptive to it and keeps trying to provoke and seduce you.

The story begins in a pub. It's around 10 p.m. and a really nice evening. But Anita has a bit of a headache, and Ken has to get up early tomorrow and has a hard day at work ahead of him. You agree that Ken will take Anita home and that Alice and you will stay a little longer.

No sooner have the two of them left than things happen as they probably had to...
