Nope never tried it. But if a woman had to suck my cock and then I came in her mouth. And then afterwards she wanted to kiss me I would. I mean if she's good enough to suck my cock it's the least I can do in return. It's just thanking her for doing a wonderful job at making my day. And then I'd probably taste it through kissing her. Small price to pay for a wonderful blowjob.
Best one was where Sabine Sweet's boyfriend was watching us film - I came in Sabina's mouth and right after the scene she walked over and kissed her boyfriend..... The whole crew about peed themselves.
