Giving? Your chances are much higher.
Receiving? Oral sex is the least likely to result in the male getting the BJ an STI, statistically speaking.
Obviously, the risk goes up in the instance of a GH because s/he is literally sucking off and receiving as many as a dozen dicks an hour and all of the sperm that goes along with it.
In my experience, I only go rarely for that reason, but both times I went there is only a small amount of time that I spent in both girls' mouths. Usually, they suck on your cock to get it to full mast, then stroke it for the rest of the time, adding saliva as necessary until you nut. Unfortunately, you rarely nut in their mouth and they usually stop stroking as soon as the first drop of cum appears at the tip of your dick, mostly because they don't wanna get drenched in cum.
This helps them conserve saliva and prevents lockjaw, as well as avoiding STIs. It is EXCEPTIONALLY rare that any penetration occurs in the ass or pussy and both times I've went it was strictly mouth and hand stuff, even if the second girl had her bra off by my third go-around and her pierced titties were covered in cum.
tl;dr since it's a group sex setting and no one wants a BJ with a condom, your chances are much higher, especially if you're the one doing the sucking. For this reason, I only go every once in a while.
