They both were apparently taken with the phrase "big girl panties" and neither of them had a clue what it meant. Susan stripped Bernie expertly. He was flat on the bed except for a single perpendicular member protruding from the crotch area. Susan knew how find the important features of a situation. She straddled him again and walked on her knees until his erection impeded further progress. Susan was undeterred. She brought her knees together as much as she could, raising her pelvis. She pulled his dick toward her and it just cleared her outer lips. She scrooched up an inch or two and settled onto it, pressing the head into alignment with the entry to her pussy hole. Slowly, she lowered herself onto him, slowly she approached her outer lips to his balls until she was sitting right down on them and his swollen member filled her body.
"Bernie! Bernie! I love you so much."
"I know, Susan. As much as I love you."
Slowly, she rocked back and forth on his dick. There was very little movement in and out but the thick base of his dick pressed her pussy now here, now there as she rocked back and forth, rotated her pelvis clockwise, reversed and rotated it counterclockwise. For Bernie it was a challenge to see how long he could delay cumming. When he was young, it was not for very long but now, in his early fifties, he could wait as Susan fucked her pussy on his dick. He loved sensing her rhythm, the rhythm of her movement and the rhythm of the grabbing of his cock with her pussy muscles. He inhaled her musky odor and he could feel his anal sphincter and the muscles of his pelvic floor contracting. This was Bernie and Susan's private heaven, a place they had created by years of fucking together. They stayed in it for a very long time. Sometimes, Susan could have an orgasm from simply holding this position. Sometimes she would prompt Bernie, as she did tonight.
"Touch it, Bernie. Touch my clit."
And he did, gently, teasing it, pressing it against the dorsal nerve of his dick and, finally, rubbing it with his thumb in a clockwise circle. Slowly...slowly...a little less slowly. Her pussy grabbed his dick. When it released a little he rubbed a little faster. She grabbed him again. Again, he waited for the release and began rubbing in the circle again. The clit was totally engorged and he pressed it a little harder. He moved faster in his circular pattern now. Every time Susan's pussy relaxed a little he rubbed a little faster, making it squeeze him again. Susan, like Bernie, actually tried to put off her orgasms as long as possible. Always she failed. At a certain point the stimulation was overwhelming and Susan began coming on his throbbing dick. When she did, he allowed his orgasm to proceed, pumping his cum into her pussy as it throbbed on top of him. It seemed they came for a long time until Susan collapsed on top of Bernie's chest.
They both slept, as they always did, right were they lay after the collapse.
When they awoke they looked into each other's eyes deeply. Their connection was plainly visible to each in the other's eyes. Nothing needed to be said. Everything important was clear to both of them.
Susan said, "I can't fault the kids for wanting sex. It takes time to learn what we know. Sometimes they think that some device or some clever idea or fantasy can approach it. The truth of it and the whole of it is in our own sexual response. Everything else is just a way to poke at that area of the brain, hoping to touch it."
Bernie said "Some day, if they are lucky, they will have this. I hope they do."
