The Classmates Rewriting the Script in the School Play

We are college classmates and actors in a school play, which we are rehearsing by ourselves (without the director). Our characters in the play are BF/GF and there’s a scene at the end of the play where we kiss. We start kissing and, following the script, it doesn't feel right. It feels that our characters will go further. I convince you, gently, that you should follow my lead and the more we're making out the harder the thought of having sex gets. The script is odd and they should teach us the real version of the story, I make you grab my boobs , touch them and suck them. We finally get at the sex scene that we are rehearsing and we start fucking slowly then go harder and faster until we both reach climax and you fill me with your cum, as we were in the character. That's what our characters were supposed to do. Imagine the crowd watching this scene.
