That's cum inflation, not pregnancy.

Looks like Duo Radon. Does about as much male stuff as female, more unbirthing and stuffing than oviposition, but quality stuff. http://www.furaffinity.net/user/squeakie/
Calling BS, tripper's work is 80% inflation, the night fury is definitely inflation/stuffing, and the inexplicable puff series is heavily leaning towards inflation, not pregnancy. Fairly sure tripper even explicitly said to someone, the raptor girl is not pregnant.
