It starts innocently enough. Two sisters used to competing over everything in their life. You come along and show them a good time, on your boat, and they get jealous of the other still being around. Finally you ask to take a picture of them and they stand together and start jostling to pose for the picture. You make the comment "it looks like your 'girls' are fighting". Referring to their breasts in contact. Blue says laughing " my boobs would totally kill hers." Pink says " you wish, sis." You decide to take a change. "Hey, girls. No reason to FIGHT over me." They start pressing into each other their firm young breasts pressing together side by side. They are laughing as they tease you until both try and win your approval. Neither is backing down and they say " you have to choose which one." You smartly say " I am about to take off on a cruise around the Caribbean islands. You two get to decide who goes and who stays."
Who wins and how far do they take the challenges.
