Now if the wife be left free to move, as just described, and the
in-and-out motion proceeds as it should, what immediately follows will
vary in a great degree. Thus, the time taken to reach the climax, or
last act of the performance, may be a few seconds, or several minutes,

especially the latter, and their skill in manipulating this part of

The effect of this motion is to still further excite and still more

It is difficult to describe what this orgasm is like. There is no
bodily sensation that at all corresponds to it, unless it be a sneeze,
and this is only like it in that it is spontaneous, and a sort of
