He began very steadily, and with light stinging cuts which soon made me aware that I had a rather accomplished young schoolmaster to deal with my posteriors, which began to tingle most pleasantly after a few strokes. The sting of each cut was sharp, but the warm, burning rush of blood to the parts had such an exciting effect that, although I fairly writhed and wriggled under each stroke, I was rapidly getting into a most delicious state of excitement. The light tips of the birch seemed to search out each tender spot, twining round my buttocks and thighs, touching up both shaft and balls, as well as wealing my ham, till I was most rampantly erect, and cried out for him to let me have him at once. "Not yet; not yet, you bugger. You want to get into my arse, do you? I'll teach you to fuck arseholes, my boy!" he exclaimed, chuckling over my mingled pain and excitement. "How do you like that--and that--and that--and that?" The last stroke was so painful that it almost took my breath away, and I knew he had fairly drawn blood. I was furious, my prick felt red-hot, almost ready to burst, when he unloosed my hands and ancles. I seized him in a perfect fury of lust. His prick was also standing like a bar of iron; he had got so excited by my flagellation. He was turned round, and made to kneel upon the chair at once, presenting his bottom to my attack. No one to look at it would have thought the pinky and wrinkled little hole had ever been much used, except for the necessary offices of nature. The sight was perfectly maddening; it looked so delicious. As I stopped for a moment to lubricate the head of my prick with saliva, he put his fingers in his mouth, and then wetted the little hole himself, to make it as easy as possible for me. Coming to the charge, I found him delightfully tight, but I got in slowly as he helped me as much as possible by directing the head of my cock with his hand, whilst I had him round the waist and handled that beautiful tool of his, which added immensely to my pleasure. At last I felt fairly in, but did not want to spend too soon, so only moved very slowly, enjoying the sense of possession and the delicious pressures which he evidently so well knew how to apply. My frigging soon brought him to a spend, and catching it all in my hands, I rubbed the creamy essence of life up and down his prick and over his balls, and even on my own cock as it drew in and out of his bottom. My delight was perfectly indescribable. I drew it out so long, always stopping for a little when the spending crisis seemed imminent, but at last his writhings and pressures had such an irresistible effect that I could no longer restrain the flood of sperm I had tried so long to keep back, and feeling it shoot from me in a red-hot stream, the agonizing delight made both of us give vent to perfect howls of extasy.
