When she is ready, she lies down completely on the floor and you fuck her in the missionary position.
As you fuck, her passionate kisses keep threatening to push you over the edge, as does her wild athleticism. You have to stop several times, and explain that you are getting too excited. Each time you have to stop she seems to get happier and happier.
Eventually she has an orgasm, although you worry that the noise she makes is a bit too loud in the circumstances.
