Yes fix it here

Ms. Burns sighs and says to Logan "Fine let's fix it here, but we need to be quick! And nothing funny, understand?" He nods in response but of course she couldn't see this with her face firmly in his quickly hardening crotch.

You watch closely as he slowly unbuttons and unzips his pants making sure not to pull on her hair. She tries to turn to watch what he is doing, but only manages to rub his cock more making him grow even harder for her. You keep increasing her libido, making her less repulsed by the thought of his cock on her face when it happens. Logan got his pants open enough that his cock jumped out of his pants, slapping Ms. Burns cheek and splattering her cheek with some of his precum.
