This is a softcore scene, so it's time for the most important part of the scene, faking an orgasm. You need to convince the viewer that you are having the most mind-blowing orgasm of your life, even while you are not actually orgasming.
Therefore, let that cock pound your asshole harder and faster than ever, and as you do, begin to scream as if an orgasm was approaching.
C'mon, louder whore. You need to convince the viewer that this cock is bringing more pleasure to your body than anything ever has before. You need the viewer to believe that getting fucked in the ass while on your back with your legs spread like a slut is what turns you on more than anything else in the world.
Scream, bitch! Scream as if you are having the most intense orgasm of your life. Scream "Oh my God!" and "Yes" over and over again while your whole body shudders from this massive orgasm.
Once your fake orgasm is over, gradually begin to moan more quietly. Look at the camera with a mixture of satisfaction and exhaustion, covered in sweat as that cock gradually slows its fucking of your ass before pulling out of your used hole.
Once the cock is out of your ass, roll over on your side while caressing your used ass.
