While typing this I see the add above 'Sharing my wife, Husbands watch as their hot wife fuck another guy' (someone needs to proofread their adds).

My point in bringing this up is that what you won't see the same add 'Sharing my husband, Wives watch as their hot husband fucks another woman.'

'Wife watching' seems to be a normal desire/fetish/whatever and seems pretty common in the MFM crowd, most women (and I used most because I'm sure some do) do not seem to get off on watching their husbands have sex to the same degree.

In my MFM experiences I've been the 'guest star' a majority of the time. Its a very different experience from being the husband in an MFM. Still while I tend to get 'more' than the husband its sort of a natural thing, being the guest. Its still primarily focused on the woman though. Its natural because the husband can do his wife any time, but is only able to watch her in these circumstances, so it makes sense the guest would do more than the husband.

I'd say in an FMF where the females were not bi, the wife would more often feel left out if she wasn't into watching.
