What excites me enormously is being nude, on all fours, tense with desire, waiting and anticipating, while my lover is behind me teasing me and driving me wild...being taunted by his cock, him (or she with a dildo) telling me what he plans to do to me. Then, with care, and ever so slowly, he inserts the head inside me, leaving it in there for a few tense, nerve wracking seconds..then slowly working it in...inch, by inch until suddenly, with one great thrust he enters me completely, balls deep, until my heart jumps while taking my breath away, and I shudder in the sheer ecstasy of the moment.
Another thing that matches, or maybe even beats that, is when, while in the same position, I feel a well lubed finger being inserted into my asshole. And then, with the utmost of care a second one is slowly, and carefully added, and then followed by the third. Each one opening me a just little wider each time. All the while,turning, pushing, and getting closer, and closer to the final goal. The anticipation, the expectancy, and the hope are excruciatingly rapturous. The tension, and prospect of what's to come, is euphoric. And then..and then, suddenly and abruptly the seriousness and sincerity of the endeavor becomes clear and near to completion. When all five fingers are now inside, just waiting to clear the last hurdle...the last group of knuckles...the widest part of the hand...my marauder, my intruder, my lover gives one last ever so slight push further in, and whoooosh....the whole hand is suddenly inside me, sucked in, up to the wrist, into my ass, inside my body. The feeling is...beyond words...breathtaking...rapturo us. And...I love to give, as well as receive.
The Key to it all is: PASSION, SENSITIVITY TO YOUR PARTNER'S FEELINGS, AND EMOTIONS.
