Are we going to have sex soon...?

So me and my girlfriend are getting really close today we was meant to watch a film but we ended up kissing for the whole thing when we was kissing we changed positions until i was between her legs like missionary position and i had a erection and she knew i did and she also knows when she rubs her hand up my back and i like push up so i was between her legs and the only thing seperating our parts was joggers and shed rub her hand up my back and it would be like having sex thrusting up and she would lift up to then she sat on me and started like moving around on it and we kept kissing and doing this for ages......
