Demand she gets on her knees
From Create Your Own Story
"Get on your knees, I'm going to use your throat." She is startled, "I.. uh... I guess." She gets on her knees and waits as you unzip your pants to let out your cock. She immediately gets to work on sucking the cum out of you. You barely last five minutes, you can tell she has a lot of experience. You blow a load into the back of her throat, which she swallows promptly.
You've achieved your goal for the day, fucking something. You head home and goof off til the evening.
