Keith felt her hand playing with his sac, something she seemed to do well on her own without any instruction. He felt her mouth suck him harder, like she was trying to draw the pre out of him like a straw, her head bobbed up and down, her mouth making soft, sloppy wet slurps every now and then when her lips would momentarily break the seal. "Oh..,mmmnnh.,s.,shut...so good!" he panted, he felt his sack tighten against him suddenly. "Oh...damn..!" he grunted before his cock swelled and stiffened, the muscles clenching and unclenching as he came in her mouth. His cock pumped several tines each time releasing a hefty spurt into her wanting mouth.
