Probably aren’t making sure. I know someone that does atm often. You take your chances I guess.

You have verbally educate some individuals in person.

No double dipping, and never ass to pussy. The pussy hole & the ass hole 🕳️ are both very different & me personally I have no desire to get an infection, or an STD. I always have hydrogen peroxide I travel with because it’s necessary. I put condoms on my adult toys & I clean them after each use. I use different toys for each holes. If your going to eat ass, don’t think eating pussy is on the menu after, unless you are prepared to clean your mouth 👄 between, which can be a mood killer.

Ass play and wanted  a cock in her ass with a condom, I may indulge ,but my tongue not going in anyone's ass, nor anyone's in my ass. I love to kiss too, so ATM is off the spectrum - DOA (dead on arrival. Never got burned with any STD'S or any other ,and I intend to keep it that way.

She let me finger both holes while she blew me.  She was clear one per hole and no switching.  Then, she made it hot as hell as she wiped my hands off with baby wipes while deep throating me before we went to sex.

She made the time even more erotic.  And kept it sanitary.

I had a session with a hot Latina and after she attacked my mouth for a while I went down on her beautiful pussy.
She gets super wet and literally drips. I had my right hand at the top of her inner thigh holding her legs apart and she kept squirming while I was eating her out and moving herself down towards me which meant my hand was getting higher up on her thigh.

 
Before I knew it she wriggled some more and my thumb was inside of her. The question was where? I started feeling around with my tongue and did not feel my finger inside her pussy, so I concluded that it was in her ass. She was loving it and got even wetter as I started in and out thrusts with my thumb. She ended up exploding in a huge O and I lifted my head off of her and confirmed that indeed my thumb was in her ass.

 
I pulled it out and we continued the festivities with her blowing me followed by fucking in numerous positions. All the while I was very conscious of where my right hand was and didn't touch anything with it. When we finally finished I made sure I thoroughly washed my hands before I left her room. She doesn't do Greek but obviously enjoys her ass being penetrated.
