The female Ampharos and the male Charizard are from Nintendo's Pokemon and this screenshot's taken from Valve's Garry's Mod.

Looks like Charizard the ladies man is at it again, going on more dates with the ladies and making sure they became the most loveliest by making their bellies big and beautiful, including this Ampharos, who just ate lots of Golden Apples he bought for her. His plan to make his date with her as perfect as he can has indeed worked out very well and she seems to enjoy her bloated moment with him.
