I decided to try one of the massage places in FC, two milfs with big tits running it. I picked the one with the long black hair and huge rack and went in. I looked at her tits and checked them out with my hands first, did not see any marks or anything, nice tits, looked at her hands too, clean. I asked her to wash up and she said she showered, I then asked her to wash her hands.
We both stripped naked and I sucked her tits for a while. Then we stood up and she used her tits to masturbate me, sticking my dick right into her tit on her nipple. I took some oil and lubricated my dick and we continued the tit massage a bit longer. Then I spread her legs, had a look, decided not to go near it, and stood up and masturbated myself to completion while she lied on the bed. Afterward, I had this strange feeling since it was kinda cheap, only $50. I walked by these places before and asked and they always say $80 starting. Getting more nervous I asked if she had any STD I should be nervous about, which I should asked first...

She had trouble speaking English and kept smiling and said "well... little case, little umm, uh, case, case, what is the word for it?" Then she said, "k... a.. s...e...?" and she could not say what it was. So I used my phone translator and asked if she had a sexual disease and she smiled and said it's ok, it's ok.
Now I feel like total shit. WTF. I don't know what to do. I don't think what I did was high risk, I did not french her, and I did not stick my dick in her mouth or in her vagina. BUT, I rubbed my dick against her tits pretty hard, and I sucked those tits pretty hard. WTF is wrong with me, why the fuck did I do that?...
I then search sammyboy a little and saw someone say recently that two MLs on 2nd floor of FC were spreading STDs. I don't remember the room number, but the one I went to was manned by two MILFs, maybe same one? I don't know. SHIT.
What do you guys think I should do?
