"I was gonna put on a rubber…"

"No, Jim!" she sighed, moving her ass more feverishly than ever, clutching his ass with her small freckled hands. "We can get married later…"

"Teeny," Jim protested.

I could see that he'd stopped pumping his cock in and out of her twat, but even though he was holding his rod deep, trying not to move, Teeny was doing all the humping far him. One of her feet was still planted firmly on the foam mattress, the other braced against the roof of my station wagon.

"Come, darling!" she cooed, hands fluttering along his bare back. "Put a baby in me!"

"Damn it, Teeny… we…"

My eyes were open wide as I took all this in. Teeny's little belly was quivering as she humped and squirmed her ass like a wild seal under Jim's hips. I saw his back heaving as he sucked in huge lungfuls of air and tried to hold on. But finally he gave a jerk, and I saw him plunging in and out of her buttery pussy again.

"Yes, my darling," Teeny choked, her voice throaty with passion. She clasped both legs over Jim's back and threw her head around until her blonde curls were a tangled mass of loveliness.

Jim grunted wildly and jammed his cock forward again and again, driving the wind from pretty Teeny's lungs.

"Oh, Christ!" she babbled. "Give me twins! Give me triplets!"

"Damn… Jesus damn!" Jim groaned.

I could tell the sap was already beginning to spurt from the tip of his cock. Teeny's toes fanned out and she dug her heels tighter against Jim's ass as he humped furiously. I could hear the cum smacking wetly around the pretty blonde's pussy and she had begun to giggle in a crazy, almost hysterical way as her own convulsions made her back arch up from the mattress.

"Shove it deep, Jim!" she rasped.

I rubbed a hand over my face and twisted back around in the seat. It was funny how hard I was breathing just from watching two other people fuck.
