Charlie, it feels so queer--I can't bear it in further."

I stopped where I was, but slipping a hand under her, I applied my
finger to her clitoris, holding her bottom tight against me with the
other hand round her waist, so as not to lose ground. My agile finger
soon worked her passions up, and I felt her bottom give convulsive
twitches on my prick. I allowed her to become still more excited, and
then gently pushing forward found I was slowly, and almost
imperceptibly, gaining ground. My prick was then inserted almost
two-thirds of its length, when, thrusting rather too sharply, she again
cried out, and, but for the arm that held her fast round the waist,
would have unseated me.

"Oh, Charlie, dear, do stop; it seems to choke me, and makes me feel so
queer, that I thought I was going to faint."

"I shall lie quite still, now dear Lizzie. It is quite in"--this was a
little bit of deception to calm her fears--"and when the pain of
insertion passes, which will be the case in a minute, we shall have
nothing but pleasure."

So I kept my prick just where he was, but redoubled my frigging her
clitoris, and very soon brought her up to spending point, resolved that
I would not attempt complete insertion until I felt she was in the
raptures of sensual discharge. This quickly came upon her, and it was
the delicious movement of her own buttocks that sheathed my prick to
the hilt without an effort on my part, and so far from giving her pain,
made her positively scream with the intense voluptuousness of her
sensation in spending. She could not speak for many minutes, but
continued the exquisite pressures of the sphincter muscle on my
enraptured prick. But for my determination not to give way, and rather
to wait for another bout that would completely initiate dear Lizzie in
all the luxury and abandon of this delicious mode, I must have at once
vigorously finished my own course. My restraint was well rewarded. The
first words my beloved sister uttered were those of almost delirious
joy at the extraordinary delight I had given her. Never, never, had any
fuck so enraptured her. She turned up her lovely face to me, and tears
of sensuality and voluptuousness filled her eyes.

I had hardly begun my titillations on her still excited clitoris,
which, by the way, had lately considerably developed itself, when she
was as eager for another bout as I was. I held sufficient restraint on
myself to practice every salacious movement, that I mig
