Light thrusting 30 seconds after ejaculation?

Hi, I'm a female who had sex with male friend of mine, with a condom used from start to finish.  I was on top, and after he ejaculated, I continued to lightly thrust him for another 30 seconds until I reached climax myself. My question is, in these 30 seconds of continued sex, is it likely that the semen got pushed down to the base if the condom? I remember he was still fairly hard when I grabbed and held the rim down and climbed off of him. I remember seeing the semen collected at the reservior tip and I didnt feel anything sticky at the base. Maybe I'm just being a paranoid because I didn't get off of him "immediately" after he ejaculated and that would make my situation "improper condom usage" as per other websites I've looked on. Would you say I'm at great risk for HIV? I'm freaking out! Thanks for your input.

To  my experience, even the penis is soft already, the condom fits quite firmly on it, and no any semen is going out. So, if the condom was on, you're safe.

Thanks for your input..I have one more question..do you think it would make a difference in semen consistency? I've read that semen can be either thin and runny or very thick..in my case I wouldn't know since I only saw some in the condom..but if it was thin, would it have made it's way down do you think?

I'm not a big expert. Just from my experience, I have never seen semen going out of the condom, which is on. It stays always in the top of the condom, if it has been put on properly. Or if there's some air inside, then it might go about 1/4 down the penis, but never out. And that is quite usual that after male's ejaculation people continue moving for some time.
In addition, I think even if there would have been some leak at the bottom of the penis, it would be very difficult from technical point of view to go up back into vagina.
