s on one side; and
coaxings on the other, when I suddenly felt her charming little cunt
actually throb upon and give an involuntary squeeze to my prick, which
was still throbbing her. He was far too ready to stand at any time,
still more when engulphed in the exquisite young cunt he had just
initiated into love's mysteries--_bref_--he stood stiff as ever, and
Mary, at first with a shudder of fright, then with all the energy of
awakened passion, began to move her body under me. I held off from any
interference, feeling certain that if the desire came naturally to her
it would doubly enhance my own pleasure. My foresight did not fail me.
Mary's passions became fully aroused, and when so, the trifling
soreness passed out of mind, and we actually had a most delicious fuck,
in which my prick appeared as if in a vice, and Mary wriggled her
backside almost as well as the more artistic movements of Mrs. Benson.
All things must come to an end, but this did so amid screams of delight

naturally the power of throbbing on or nipping a prick, which the
French call casse-noisette. It is a great gift and adds immensely to
the man's pleasure, and I should think to the woman's too. In my
sister's case it began from the very first complete insertion of my
prick and the years that I afterwards continued to fuck her added
nothing to this delicious accomplishment, except in the variety of
positions in which it could be exercised.

The dear girl was in extasies at the pleasure she had received, and at
the pain which seemed to be past. Oh! she was so sweetly caressing that
I could not withdraw from her, and we fondled and toyed until again my
cock rose to his first vigour, and she nothing loath, began her new and
naturally taught gift of bottom upheavings and
