Katie's heels pressed into Jack's ass, and her hands clutched at his back as he methodically thrust into her. Her kisses grew desperate, and her breathing was one long, low moan.
When he felt the urge to speed up, to hasten his orgasm, he held back, forcing himself to maintain his slow and steady pace.
Katie, either intentionally or instinctively, began thrusting her hips up to meet his, and moaned incoherently into his mouth.
His orgasm, as it approached, was like the rising dome inside of a volcano caldera. He knew it was going to erupt, but the wait was killing him.
As the pressure slowly built, he felt like his balls were going to explode.
Just when he felt like he couldn't take it anymore and was going to start thrusting madly, Katie threw back her head and let out a long, deep-throated moan.
Her walls rhythmically clenching around his shaft pushed him over the edge, and he slammed his hips down and buried himself deep inside her.
