If it was herpes, it would be blisters or paper-cut like sores, and I'd expect there to be pain.
Two tiny bumps don't sound like that. Are they on the skin or under the skin? On the skin could be genital warts, skin tags, just normal skin variations, or a host of other things. Under the skin isn't usually an STD.
You should let your doctor see them to determine for sure what they are. If it's genital warts, it's not likely to be from this oral encounter, as the incubation period (time from infection to symptoms) can be months long.
