Zip

The sound of him opening his zip brought her up sharp.
Oh yes, God yes, she thought as he freed his erect cock.
She had never been keen on oral sex, but she had wanted to suck him since the first time she saw him. The firm stem reared up from the open zip, his pubic curls hidden beneath the leather. He was big and veiny. The moist reddish glans was collared by skin.
She leaned forward and dabbed at the cock-head with her tongue, lapping up a single drop of clear fluid.The hand on the back of her head exerted a more insistent pressure.
