Aight heres a simple trick to lastin longer in any situation, whether your face fuckin her, skull fuckin her, pumpin her pussy or stickin it in her pussy or gettin your wang yanked.. Just try and pee. No joke. You won't be able to pee but when you use that muscle it kind of numbs sensation in your penis. When I'm close to blowin I will try that for 2-3 seconds (It's kind of like flexing..) And then I'll be good for another couple minutes and I can keep doing. It kind of takes a little concentration though.
