Diana steps back

Diana hesitates for a moment, then steps back, releasing her hold on your cock. Sophie, watching you sit there, fully erect, continues touching herself. She stares intently at you as her hand races faster and faster across her panties. Her lips part. You see breasts tremble as she breathes faster and faster, face flushing.

"Are you...going to put me in your mouth?"

She nods, but doesn't stop. Her hand is almost a blur now, and she's beginning to let out soft gasps, delicate grunts and she works herself. It looks like she's going to cum fast if you don't do something.
