I took the end of Ruth's middle finger in my mouth and slowly sucked it in. With her whole finger in my mouth, I sucked gently and licked the underside with the tip of my tongue. Then I slid my mouth slowly up her finger to the tip, then slowly back down. Opening my eyes, I saw her staring intently at her finger, sliding wetly between my lips. I increased speed, sliding her finger quickly in and out of my mouth, sliding back and forth the length of my tongue, sucking very lightly. Every third or fourth stroke, I stopped briefly to lick the end of her finger in a circular motion. Unnoticed, I slipped my free hand down between us and followed the smooth, curving bottom of her thigh down to the warm, thick fur of her pussy. I pushed a finger into her tangled hair, probing until I found the slit between her feathery-soft inner lips. Wetness greeted my finger when I pushed inside her, and I pulled out to spread the moisture up the shallow groove of her pussy toward her clit. I settled into a steady rhythm, sliding my wet finger up and down her furrow, rubbing her pink bud lightly with each passage. Ruth gasped and looked down between us. She gave a low moan as she watched my fingers disappear into her thick bush, then reappear slowly in the dim light. Her free hand reached down and grasped my arm, but she didn't try to stop my hand from moving back and forth, back and forth. Soon her mouth was open, gasping and she squirmed slightly where she sat between my legs. I still held her middle finger in my mouth, sucking. "NO!" she whispered urgently. "It's not my TURN!" I pulled my mouth off her finger. "I say it IS your turn!" and she whimpered, her eyes drawn down again to watch my hand working between her thighs. She took a deep, shuddering breath. I increased the pressure of my finger, sliding up and down ... up and down, careful to give her clitoris only the slightest touch each time. Now she was moaning again, very low, and she leaned slowly forward until her forehead was resting on my shoulder, one hand on each of my knees. A few minutes later I could tell her crest was coming as her breathing got deeper and harsher and her hands gripped my legs. Then the wave struck and she was grunting, a deep powerful, "UNH!, UNH!, UNH!, UNH!, UNH!, UNH!, UNH!, UNH!, UNH!, UNH!, UNNNNNNNNNNNNNGGGGGGGHHHH!!!!" And her hips were thrusting wildly and she turned her head and bit me on the neck, HARD! I straightened and grabbed a handful of hair, pulling her mouth away from me. I looked down into her face, twisted with shameless pleasure and kissed her, forcing my tongue into her mouth where it battled with her eager, searching tongue as her orgasm continued. Moments later she broke the kiss to gasp desperately for air and brought her arms up, hugging me tightly around the neck. Her moans of pleasure began to subside then and she laid her head on my shoulder, her harsh breathing loud in my ear. My hand was cupping her sex, pressing, making only the tiniest of motions. After awhile, I fell back slowly, pulling Ruth on top of me, and pulled my hand away from her warm, wet pussy. She looked down into my eyes. "Please fuck me, PLEASE! I need you inside me right NOW!" I rolled on top of her and, lifting my upper body, reached between us for my dick, throbbing and thick. She spread her legs wide and instinctively tilted her hips up. I wetted the fat head of my dick by rubbing it up and down her dripping slit, then fitted it into the mouth of her vagina. "NOW!" she insisted, and I drove my entire weight down, spearing her to the hilt in one motion. "UNNHHH!" she grunted at the impact. "Oh GOD! Oh GOD! Yes, YES! The slick warmth of her pussy encased my dick. Slowly I withdrew until just the head of my dick was inside her, then I dropped my weight again, impaling her, then slowly withdrew and did it again. Ruth held her breath each time I made my slow withdrawal, then grunted as my dick split open her sensitive inner walls and the base of my dick pressed down on her straining clit. She began rocking her hips up to meet my assault, her hands locked on my upper arms. Left and then right, I pulled Ruth's legs up until her calves rested on my shoulders, tilting her hips up, and doubled the speed of my thrusts. Soon she was uttering a high, "OH!" each time my hips thumped home against her crotch. "OH! OH! OH! OH! OH!" she cried, staring up at me wide-eyed. "Oh, I'm going to cuuuuummmmmm! Another minute passed as the tension built in her body, then, OH! OH! OH! UuuuunnnnnnhhhhhHHHHHHHH!" And she was arching up towards me, her hips thrusting, eyes closed, head thrown back. I could see Ruth's full breasts jerk slightly each time I drove into her. Her pussy seemed to squeeze my dick and the extra friction coupled with the excitement of watching her come brought me to the brink. My thrusts became even faster as I soared over the edge and began to burst inside her. Ruth felt the change and heard me cry out, "AAAHHHHHHHHHHH!" Her eyes opened and she began rolling her hips up to meet mine. "Come on baby! Come in me baby!" in a strained whisper. "That's right sweetie. Fill me up!" I had no choice. My come felt like molten lava flooding from my balls and shooting out in burning jets. I might as well have tried to stop an erupting volcano. Then I collapsed forward onto Ruth with a final cry, my hips still thrusting weakly. She wrapped arms and legs around me, soothing and caressing with her hands, whispering in my ear. I could feel her pussy lightly squeezing my spent penis. We laid that way for a long time, resting, and I finally rolled over so we were side by side, arms and legs still tangled, and we fell asleep.
