FELLATIO
Fellatio, known by a variety of colorful names such
as "giving head" or "giving a blowjob", is the act
of applying the lips to the penis. It's quite a popular act with
men, to say the least. It brings great pleasure and stimulation
to the lucky man receiving it, and quite often, the woman or man
giving it.
The lips and the tongue are the major sources of
stimulation, and it is with the lips and tongue that you should apply
the attention to make him feel good. Both men and women respond
well to pressure and rhythm. A steady, strong stroke will be enough to
get the reaction you're looking for.
