Oral sex and HIV transmission

Hi all,
I am a little uneasy. My bahelor party was on the weekend and my friends hired two escorts from a licensed agency. I never made contact with either of them with my penis. During one part of the show, I was bound, and the escort placed a sex-toy in her vagina. She put lube and a condom on it prior to putting it in. After whe was done with it, she removed it and about 30 seconds later, I believe with the condom still attached, placed it around my face and actually into my mouth. This lasted about 5-10 seconds in my mouth. The girls say they were clean, but I am worried about a possible HIV transmission. Is it possible to be infected in this manner? If not HIV, what other STDs could have been passed during this disgusting episode. I am not in a panic, but I am sufficiently anxious. I have felt a sore throat since the episode, about two-three days ago, and my tongue has a very minimal amount of this white coating on it.
Thanks for the help!

No it is not possible to be infected with HIV in that manner. As for other STDs, you'll have to post on the STD forum.
