Here's THE way to give a blow job: toungue lavish the head, paying particular homage on the tip ridge on the underside, where it forms a V. Randomly bob up and down over the tip tight lipped at varying speeds. Only the upper half of the shaft needs to be taken in the mouth. The base of the shaft is firmly held by the "OK" fingers of one hand, while the other fingers of that same hand gently envelop the ball sac. Several fingers of the other hand lightly trace a teasing path from the balls to the asshole. They are also to gradually tease entry into the anus, making sure to swirl around the hole to enhance the tease. Occasional light tongue flicks on the cock head are nice, as is humming your appreciation of it. Just when things reach the boiling point, the free hand starts to enter the anus, gradually adding fingers as tolerated. Before any more than two fingers have penetrated, they are to be hooked upwards and their tips gently rub the prostate. Once imminent ejaculation becomes apparent, sucking and head bobbing increase in speed and intensity while the inserting fingers are shallowly going in and out of the anus. What you do with the after effects is contingent upon mutual consent.
