She had no risk of HIV because a person can't get HIV from oral activities like kissing, licking the wire or from touching HIV on the wire. She is so safe that you don't even need to have her do a test.
HIV is instantly inactivated in air and also instantly in saliva which means it is effectively dead so it can't infect from any oral activities or from touching it on the wire outside its host. It doesn't matter if both of them were actively bleeding at the time either because the HIV is effectively dead.
Only child non-sex risks are sharing needles that you inject with but she didn't do that so she had no risk. This sentence is all a person needs to know to protect themself against HIV.
Even with blood, lactation cuts, rashes, burns etc air and saliva do not allow inactivated virus to infect from oral activities or from touching it in the air outside its host. The above HIV science is 40 years old and very well established so nothing you can add will make her situation a risk.
