Fay's from Nintendo's Pokemon, Jon Talbain's from Capcom's DarkStalkers and this screenshot's taken from Valve's Garry's Mod. It is done through Rushmao17's choice as part of the celebration of late Valentines and late Easter days.

Jon seems proud to become a daddy in the future and walks happily to feel his and Fay's puppies kicking inside her doggy belly.
