Yes, you do

You head straight down the stairs, your sisters tender breast and virgin cunt the only image in your mind. After stumbling over chairs and a couple of your little brothers toys you make it to your sister and immediately lock lips with her, ignoring everyone else in the room whose faces are now pale with shock as you **** your tongue down your sister's throat. To your surprise she joins in the action and you are now making out with your sister in front of your entire family.
