I find with some of my clients they get instantly hard when i do owo but as soon as I put on condom they start losing it.
Same with sex after they have been going a while. End up having to take it off and give more owo then they Preston instant erection. I asked one about this and he said oral with dulls the sensation and he doesn't feel any pleasure so doesn't see girls who do oral with as he doesn't enjoy it.

Some other questiond as I'm interested in trying this as well.

1. How did you have the condom on with you before the action started? I typically have them next to the bed and when they get undressed, then I get to see which size condoms to use.
2. How did you get it into the mouth before blowing them without the punter noticing?

I'm always reaching into my bedside drawer for toys and lube. They're pretty distracted. I palmed the condom and kept it out of view.
