Spec your thing but this is the dark arts son.
I've swapped pockets with pros tons of times (Walmart Craigslist level) because I'm not there to deal with the consequences so I can be absolutely fearless and enjoy the spluttering, but...
When I was married, my wife and I did this a few times and the consequences were constant infections, both internal in the organs somehow and also just all up in her pussy.
Here's what it's like. Imagine you were eating some good, bitter dark chocolate but then it had the juicy-ness of the world's juiciest orange. Mixed all together and spreading around. Imagine it, then reverse it. Imagine it bro, that's what it's like.
So anyway respec your fetish and dig into it because it's hot as shit still.
For recs, triciafox the cam girl used to do this all the time. There are a bunch of vids with her doing it to herself with a dild, PLUS one where her and another bitch switch pussy to asshole to mouth and back again between themselves and each other with one big double ended dild.
Anyway that's it bro keep up the good work you're getting after it. Get that juice.
