"Slap my arse; bugger me; shove your prick into me as I fuck her, and you shall be well paid!" he almost shouted, throwing himself on his sister, and beginning to fuck fast and furiously.
"My pet, my love, my own Diana, no one shall ever marry you, you darling, although I must first be excited by seeing some beautiful boy have you. And you, sir, make haste to help me behind; it's the only way I can really enjoy my sister!"
Prick was ready again in less time than I can write it; the sight of a brother fucking his sister so excited me that I began to slap his bottom with my open palm as hard as I could with one hand, whilst the other was busy feeling his balls and handling the shaft of his fine stiff penis as it worked in and out of that lovely cunt.
"Fuck me! bugger me! or I can't spend!" he exclaimed, so nothing loth, I lubricated his fine hairy and wrinkled arsehole with spittle, and bringing the head of my cock to the tight-looking orifice I speedily effected an entrance.
What a fuck that was! He was evidently rather slow, although awfully excited, and both his sister and myself having just emitted a profusion of our essence of life, we were not so quick in reaching the spending point.
With both hands I frigged him, and tickled her clitoris, as he fucked away, whilst my prick was as lively as possible in his posterior aperture.
At last we came, and all three almost at the same moment; our bodies fairly quivering again and again as the electric thrills shot through our excited frames.
At last it was over, and both of them overwhelmed me with caresses till it was absolutely necessary for me to take my departure, when Lady Diana hastily selected several pieces of silk, whilst the marquis pressed a ten-pound note into my hand, and assured me I would very often have a chance of obliging both himself and sister again.
For a period of two years I continued to be their favourite, till, Lady Diana's health failing, the marquis took her to Naples.
