Yeah, like xw5 said, I would imagine that there are totally different types of duo bookings. For example, a pair of lesbians could work together offering a limited-interaction but full-on show type of booking. Or a pair of straight girls could work together with limited interaction with each other but full services with the client. And probably everything in between!
Someone else posted here about only being able to do duos with other escorts that she didn't know well because they could make friends afterwards but there wouldn't be the awkwardness of being friends first and then suddenly getting naked and acting out some guy's fantasy - cos despite what dumb men's mags suggest, I don't find myself wanting to ever see my mates' ladybits! And if I ever did want to have an experience with a woman in the future, I reckon it would be with a specific/special one rather than just OMG ANY BOOBS WILL DO, ha. But yeah, it goes to show how completely different we all are and some of the complications that can arise when navigating the world of sex and sex work, especially when three or more people are involved!
I love the idea of doing duos sometimes because it sounds like there'd be two of you fielding the normal intensity of the booking - I mean, like if the guy starts gazing into your eyes and asking you whether you like Thai food, you could just get your friend to sit on his face. Alternatively, if he starts getting arsey, rude, sneaky or weird, you and your friend can watch out for each other and protect each other. Everybody wins!
Unfortunately, I'm getting the hair lasered off my bits at the moment and can barely look the technician in the eye after each treatment so I think working alone is the only way for me.

Overall, I reckon it does really depend on your individual needs, plus the qualities in the potential other escort, and maybe a few other random factors that only experience would show up? So maybe just try contacting a few others who advertise as bisexual (or you can put an ad in the right section of this forum) and take it slowly (sort of interviewing 'em!) to see how it goes? This particular clients' demands might not be met but at least once you've found a friend or two that you can work with comfortably, it'll be easy to sell duo bookings and perhaps even make extra money together.
