Teasing unzip under desk turns into slow suck

Late night coding session dragged on, but she couldn't stand another minute of him ignoring her. With a mischievous grin, she slipped under the desk, her pigtails brushing his knees as she knelt topless between his legs. Her fingers traced the zipper slowly, building the tension until she tugged it open, freeing his thickening cock right there by the keyboard. Eyes locked on his from below, she leaned in, her warm breath teasing the tip first. Then, with deliberate slowness, her soft lips parted, enveloping the head in a gentle suck that drew a low groan from him. Her tongue swirled lazily, savoring every inch as she took him deeper, the faint wet sounds mixing with his ragged breaths, making the screen blur in his vision.
