Shower her with praise...

She continues to suck you with gusto. Her gaze is split between working your member and watching your face for feedback. Your girth widens and she knows you are close. She needs you to know that she is committed with everything she has. Her mouth strains around your dick but she knows that how well she pleases you will be the most important moment of her life. Her future, the future of her family, is riding on these next few moments.

You grip the side of your desk. You've accidentally kicked your chair back and it rolls across the expansive office. You withdraw with a moan from her and begin to fire cum wildly. She intuitively sticks out her tong and thrusts her tits out. One blast catches across her chin, mouth, and cheek. Your dick violently spurts again a shot into her eye and hair causing her jerk back. Her exposed tits and stomach take the next two blasts, and you **** yourself to stop with a final spludge across her shoulder and back.

"Aaaaaaahhhhhhgggh"

The room stops spinning and you open your eyes. The girl is cuffed at your knees. Drenched in cum. A look of exhaustion and pride on her face. She looks over at her parents. Her mother is still flushed from subsiding arousal in her chair. Her father nervously plays with his hat in his lap.

You don't say a word at first. You clean yourself with some tissues from your desk. Calmly adjust your pants and collect your desk chair. You look down at the cum covered girl and then to her father. You've made your decision.
