The brunette.

As if on cue, the hot brunette slides off the table onto her knees, and locks eyes with the nearest painter. He looks to be the youngest of the group, probably a freshman. He remains frozen in place as she slinks towards him on all fours.

Once in striking distance, she pounces like a jaguar onto his belt buckle. With startling speed, she yanks down his Dickies and is rewarded with a gentle slap to the nose as his erection springs free.

The poor freshman barely manages to gasp "ohmigod" before the brunette rises a little on her knees, positions his cockhead at the entrance of her puckered lips, and slides her head down his whole shaft.

The kid cries in what sounds like pain, but obviously is not. He doubles over, and manages to stay upright only by steadying himself on the girl's shoulders. Unfortunately, this traps the girl in place and forces her to take the freshman that much deeper inter her throat.

The brunette's eyes bulge, but she doesn't panic. You catch a glimpse of her expert skill: the suckling lips, the telltale signs of tongue activity under her cheeks, the undulation in her throat.

The freshman doesn't stand a chance: in seconds, it's all over. His cries peter out to a pathetic whimper. He relaxes his grip on the fellatrix's shoulders, allowing her to dislodge him from her throat. As soon as she pulls his dick passes her gums, she smacks her lips with a satisfied and exaggerated "Aaah" -- the first thing you've actually witnessed come out of her mouth.
