You have discovered the secret, well kept by upper class English schoolboys - that the bottom and cock can unite to provide near heavenly horny sensations. The ring of your hole is now around the base of my extremely stiff shaft. As you feel the end is near - you gasp, and involuntarily, cum spurts from your cock, in quick pulses, onto the sheets. I withdraw - the condom dangles with the weight of the captured spunk, my cock collapsing - its work completed. Too tired to get up, you hear me getting dressed and leaving the room, without a word.
