In theory, you'd be at risk for genital hsv1.
In practical terms, very brief oral sex with a condom probably doesn't create a risk level that you need to worry about.
Most experts don't think that one act of oral sex warrants testing. I wouldn't worry about this if I were you.
Oral hsv2 is rare, and when it happens, it rarely recurs, rarely sheds, and therefore, very rarely transmits. I wouldn't worry about genital hsv2 from receiving oral sex at all, even if it was longer and unprotected.
