His face between Erin's splayed legs, Jim examined her crotch. The pink, wavy folds of her labia had opened slightly, releasing a musky scent into his bedroom. Her pubic hair was tidy, a dusting rather than a bush, with a few longer follicles sticking out around her vulva. It was light brown in the sunlight streaming in through the window. There was a large mole just to the right of her clitoris, only slightly darker than the pale skin surrounding it; the clitoris itself was small and oval in shape and was at that moment just a glimpse behind its hood. He hoped to make it stand up more proudly in due course.
Jim extended his tongue and placed the tip in the sweaty, bright white perineal space just below the bottom of Erin's vulva. He pressed his face in close and dragged the full length of his tongue slowly upwards, feeling each contour of her lips as he went. The taste was rich and sweet and acidic. "Uhhhh," she responded. He made an effort to apply extra pressure along the length of her genitals and work a little of his tongue inside her as he went, then released the muscle tension as he reached the clitoris, not wanting to jar her out of her reverie before she was switched all the way on.
Jim himself was also naked, also pale in the daylight, and lightly coated with dark hair except for the unkempt growth around the base of his penis, which grew partially erect as he worked. His wide shoulders rested against her soft thighs. His bare feet dangled off the end of the bed. Erin noticed this, a glimpse over his round buttocks in-between sighs, and thought of the mythical connection between foot size and penis size. It was certainly true in Jim's case, although he wasn't too big. The day so far had proved he was just right. She couldn't wait to have him fill her up again.
For now, though, he continued to busy himself in her crotch. More slow strokes of his tongue along her vagina. Her nipples stood on end, light and indistinguishable in colour from her wide, patchy areolae but for their raised hardness. With each pass, he pushed a little deeper into her as he went, and began grazing her clitoris with his lower lip before returning to home base. It was exquisitely frustrating. She was desperate to be squeezing his cock again, but this drawn-out focus on her was holding her on a sensual plateau, filling her body with incomparable tension. It was a constant struggle between deep comfort and twitchy desire. Blood pumped around her body at an increased rate, heating and enlarging the tissue around her breasts and crotch. Her face grew red and her mouth dropped open, inhaling air in quick bursts in order to stay afloat.
This time, he let his teeth catch momentarily on her protruding clitoris, ratcheting her arousal up a tiny bit further. She was sure she wouldn't come like this, so she tried to relax into the joyous feeling coursing around her body.
Then Jim stopped at her clitoris and closed his mouth around it, and suddenly she felt her orgasm rushing up out of her pelvis, pausing momentarily before he sucked the nub around his tongue and brought her to the very edge.
She pushed at his hair, gasping. "Stop, stop, stop, stop, stop."
"Are you okay?" Jim asked, looking up at her from above Erin's damp crotch.
"Yes. No, I'm just..." She stared into his eyes as she thought about what should happen next. "I want us to come at the same time."
"You want me inside you again?"
"No. No, you have to stop coming inside me." She laughed, but she meant it. "Come up here."
"Okay."
Jim moved her leg out of the way and crawled up to kiss her, laying his body along her side. She tasted herself on him and felt another surge of arousal. I wonder why I like that so much, she wondered to herself. Maybe I just taste really good.
As Erin sucked his lower lip into his mouth, Jim felt his semi-hard penis become fully erect against her hip. With her left hand, Erin reached down and guided Jim's right hand to her crotch.
"Like this," she said, positioning his ring and index fingers either side of her clitoris. "And a finger inside." She giggled. "If you can."
Jim smiled, got his hand in position, and began working at her. His middle finger slipped inside her easily. He worked it back and forth against the upper wall of her vagina while the palm side of his lowest knuckles shifted pressure around her nub. "Ahhhh," she sighed. "Yes, that's..."
She took hold of his penis and pumped it slowly from tip to base, covering the shaft with an abundance of precum. "Ah," said Jim. Up and down went her closed fist, faster and faster. He increased his pace to match hers. They grunted together.
Very soon, Jim felt his orgasm rising again. His foreskin appeared and disappeared inside her swiftly moving fingers. His balls bounced against her pinky knuckle.
Erin flew to the brink. With her free hand, she clutched at her left breast. Jim's buffeting of her genitals creating a more significant churn inside her. Her stomach undulated as she reached for more of his touch with her pelvis, willing her orgasm to come out and meet him.
It was beyond any rhythm now. As if they were attacking each other.
They grunted and gasped and kissed, eyes fixed on their writhing lower halves, mouths permanently open.
When he noticed a damp spot on the sheet under her temporarily raised buttocks, Jim ejaculated three bright white shots of semen onto her stomach. One partially collected in her bellybutton. The others ran down her side, joining their earlier fluids in staining the sheet. Through a haze of full-body bliss, he wondered if she would ever fail to produce such volume from him.
When Erin felt the charged fluids fly down the shaft nestled in her palm and into the air above her body, she came. The warmth on her skin of the second spurt from Jim's erection intensified her ecstasy, and she pushed up against his fingers, ass muscles flexing spasmodically. She cried out at a high pitch. It was her fourth orgasm in twelve hours and somehow attained greater heights than the previous two. Maybe it was being able to actually see his come explode out from his body; to see the physical manifestation of the pleasure her body had given to him. But she had loved the feel of it at the apex of her vaginal canal, too... and as she thought about that, she wanted to feel him come inside her again. Dangerous.
They lay there in the sun, their naked bodies limp against the sheets and each other. Jim's now-flaccid penis lay against her hip, and two trails of semen ran past it, away from her center.
But it was too late. Their future was already decided.
