I 've done it about 4-5 times. It didn't taste bad or anything but it's very hard gor me to swallow. I just cum in my mouth, keep it there for a sec and then spill it out. There's a secret for those of you with a bad cum taste: before cumming, put some white toothpaste (mint or something) in your mouth and chew it for half a minute, then spit it out. After that, cum in your mouth and you 'll see that the taste is gone!
