Cactus Surprise

When you're banging your bitch and when she just about to climax you pull out and yell "I'M GOING TO PUT A CACTUS IN YOUR VAGINA" and then proceed to put a banana up there instead. The surprise is that there's no cactus, there's banana.

Guy: *pulls out, prepares for a Cactus Surprise* "I'M GOING TO PUT A CACTUS IN YOUR VAGINA"
Girl: *screams*
Guy: *puts banana in her instead*
Girl: *screams, but not from pain*
