Three "friends"

(NSFW warning. Viewer Discretion Advised) (Also sorry about the voice, I couldn't do more than one voice) - Terry, Joseph, and Juliet are at a mutual friend's birthday party. They didn't expect to see each other and socialize for a while. Its a big party, and they talk for a while before Juliet gets an idea to bring them in the room. They talk for a while and can hear each other better. Eventually, no one knows what happened but they start doing things to each other. Terry is the top, due to being larger than both of them. He is 18. Joseph is the middle. He is 17. Juliet is the bottom, due to being smaller than both of them. She is 16.
