Am i at risk of contracting any sti and hiv?

I went to a massage parlour earlier this morning in Sydney, Au. After recieving a back massage for about half an hour i asked for extra from a young asian lady around 23-30 years old. After having a lubricated handjob for about 10 minutes she agreed to me ejaculating on her bum but before this i had put in unprotected in her vagina for about 5 seconds. After i pulled out and ejaculated we wiped oursrlves of with wet wipes and to which she noticed a small spot of blood (she was about to start her periods). I looked at mine and so no signs of blood to which i asked jer if she was clean. She replied that she was pretty confidently and said she had a blood test recently and said she was 100% clean. I live close by so i rushed home and was in the shower under 5 minutes from the exposure and cleaned myself down there quite vigorously.

Considering the few seconds of penetration im guessing my chances of contracting are low.
Does the fact my penis was quite lubricated help reduce as it would of sought of create a barrier? Would also thr fact i wiped myself straight after and have a shower not long after also help?
