Relieve the tension.

"Well..." Beth stepped forward, staring at that bulge. "It seems to me, David, that I can't leave yet. I haven't done a thorough job relieving your tension..." her hands touched the tent in his pants, and David gasped.
"Beth! I...."
"What? Don't deny it... you want this..." Beth could barely believe her own words. Her inner slut had the reins, and the outline of David's cock against the fabric of his pants had her mouth watering. "How can you be expected to work with a clear head when you're all... stiff like this...?" She reached up to grip the back of his neck and kiss him again, using her other hand to attack the clasp of his belt and then his pants' button and zipper with expertise until she could slide her hand inside his briefs to grip his stiff cock. He moaned against her mouth, and she knew he wouldn't object any further.
After freeing his beast and stroking him for a bit while exploring his mouth with her tongue, she gave him a little shove to fall back onto his chair before falling to her knees to take his thick-headed member into her mouth.

"Beth...Jesus....that's amazing..." David stroked her hair gently as she sucked and slurped and stroked.
"Under oath, counselor... you've fantasized about this....about me, yes?" She batted her eyelashes at him while stroking him with a tight grip, and he nodded enthusiastically.
"Yes... yes..."
"Doesn't Kim suck your cock, David?"
"She.... she doesn't like it..." he whispered, eyes threatening to roll up into his head. "She never does it very long..."
Beth responded by taking his cock all the way down, making her eyes water and threatening to gag herself. David let loose a quiet string of obscenities, and his hand became a little more forceful on her head.
