Moaning around his cock, she rolled her lips over her teeth and tightened them around his shaft, sliding down until the head pushed at the back of her throat.  Tongue flicking back and forth across the underside, she sucked gently and began to pull back, stopping as she reached the head and teasing the head of his cock with the tip of her tongue.  Her hand still steadied his shaft, the other one cupping his balls, kneading them lightly.
