Yes. If a woman hyperovulates and releases two eggs, it is possible for the first man's sperm to only survive to find one egg, and the second man's sperm to find the other egg. But the intercourses have to occur within a certain time of each other (usually by 24 hours since that's how long released unfertilized eggs are fertile for?). Very uncommon in humans, but possible.
It's called
Heteropaternal Superfecundation.
