You can do a review search for "two guys"
to find providers who are into that.

In most cases, it means you bring the guy,
unless its a provider you are a regular
with, and you discuss it beforehand, and she
discusses it with another regular who's into it.
And both of you would be donating then.

In most cases, it means two straight guys.
Only a few providers are into MMF bisexual
fun and watching male-on-male activity.
