i think that they’d be hella shocked, because you guys are obviously super careful when it comes to birth control and protection. (they’re super good at pulling out too, bc lbr, their pull out game is strong) 

but i think after the initial shock, they’d obviously would want to get the elephant out of the room, so they’d do a paternity test so they know that the next time you get pregnant, they can assure that they will at least have one kid each!
