In the position just described, if the wife has her arms around her lover’s body and her heels in his knee-pockets, while he supports himself by his elbows and knees over and above her, resting none of his weight upon her, it is perfectly easy for her to lift her hips up and down, or sway them from side to side, or swing them in a circling “round-and-round” motion, as she may choose to do.  She can thus originate her half of the in-and-out motion—­a something she will delight to do, if given a fair chance. If, however, the man lies heavily upon her, holding her down with the weight of his body, the possibility of such action on her part is prevented, and this results disastrously to both parties.  And so, in this part of the act, the husband should take the utmost care to give his wife the full and complete freedom to move her hips as she chooses, and as a successful climax demands that she should.

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, may require a mere half dozen motions, or several hundred! All depends on the intensity of the passions of the husband and wife, especially the latter, and their skill in manipulating this part of the act.

The effect of this motion is to still further excite and still more distend all the organs involved.  Normally, the motion grows faster and faster, the strokes becoming as long as the length of the organs will possibly permit without separating them.  The flow of the lubricating fluids, from both organs, becomes more and more copious, till, all at once, the orgasm, or fourth stage, is reached!

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 nervous spasm (a sneeze is sometimes spoken of as an orgasm).  A sexual orgasm is a nervous spasm, or a series of pulsating nervous explosions which defy description.  The action is entirely beyond the control of the will, when it finally arrives, and the sensation it produces is delectable beyond telling.  It is the topmost pinnacle of all human experiences.  For a husband and wife to reach this climax, at exactly the same instant, is a consummation that can never be excelled in human life.  It is a goal worthy the endeavor of all husbands and wives, to attain to this supreme height of sexual possibilities.

On the part of the man, the orgasm throws the semen into, and all about the vaginal-uterine tract.  The amount of semen thus discharged at a single climax is about a tablespoonful, enough to entirely flush and flood the area into which it is thrown.  Its use and action there have already been described, and so need not be repeated here.
