Yeah in that case I guess anything can happen and it would make sense.
The cum part isn't really bad. It's a bit salty and has an earthy aftertaste and has the consistency of stringy tapioca. Sometimes it'll pick up an aftertaste after certain things are eaten too. Broccoli and asparagus come to mind. If a guy I was going with ate broccoli a few hours before, I won't blow him. If I did, I would end up yarfing on his stomach.
The thing about cum is to get it past your taste buds pretty damn quick if the guy DID eat something unpleasant.
