Kate's Cake20

Kate, Josh and you have been inseparable since always. The neighbourhood knows perfectly the three of one and when one of you they already ask "where's is Josh? Or Kate? Or you?" That kind of friendship. But, in that kind of friendships there's always somebody who falls for one of the group. In this case, things happened when you were 15, and you and Josh decided to admit your feelings for Kate nearly at the same time. Kate, on the contrary laughed out loud saying "Guys, you are like my step-brothers, I could never date any of you!" Things got weird a couple of weeks but then everything returned to normal. You all gott to college but the friendship remains, and as you all grow up, Kate's sexuality developed too and her encounters with men become a usual topic in your group. So, here we are, in her 20th birthday. As you have done since 15 years ago, she invited you over to her house to order some pizza and play some video games or watch a movie. If this is the plan, why is she wearing a bunny suit?
