Kathy could see the dew coating her sister's fingers and the flexing of the fleshy lips as her finger sliced back and forth through them. Her own slit was on fire. She could hear the soft wet sounds her fingers were making as she coaxed herself closer and closer to coming.
"Unnnn!" Beth half sobbed. Her little body was jerking and her hips flexed. Her head idled back and her mouth drooped open.
"Uh! Uhh. Uuuuunnnnnhhhhhnn!" she grunted and then gurgled. Her small body stiffened and she shivered.
Kathy felt the tension reach a peak in her body. The little hole an inch from her fingers clenched and spasmed. Then the dam broke and she felt the first spasm bubbling up through her straining little body.
"Aaaaahhhhhhhh!" she sighed. Waves of pleasure rumbled through her.
The pleasure began to ebb and she and Beth looked at each other and smiled. Both faces were flushed and their breath was a little fast. Their fingers still lay between the lips of their small slits, motionless.
"Good?" Beth gasped.
"Delicious!" Kathy replied. "You?"
"Same. Did it seem to make it better, having someone else doing it?"
"Umm hm!" Kathy hummed.
"Me too. Let's do it together, when we can."
"Okay." Kathy was letting her finger move slightly in her slippery crevice as they talked. Her eyes dropped occasionally to her sister's little slit. She had a strange curiosity stirring deep inside her. She wasn't sure just what it was, but she felt it.
Beth realized that Kathy was watching her and fingering her slit and felt a similar feeling welling up in her. Her fingers began to move slowly.
They watched each other's fingers and looked up, their eyes meeting. There was a strange, hungry look in Kathy's eyes. Beth felt a surge of heat run through her.
"Are you thinking what I'm thinking?" Kathy whispered.
"I think so." Beth's answer was almost inaudible.
Kathy's fingers lifted from her slit and reached slowly across the gap between them. Her wet fingertip timidly touched Beth's rigid nipple. The younger girl winced and then pushed the nipple out against the inquiring finger. Throbs of sensation ran from the sensitive button and down through her body. She moaned softly and looked cow-eyed at her sister. Kathy flicked the nipple slowly, and reached across to lift Beth's free hand. She drew it up to the small hard knots of her own breasts. Beth held her breath as she felt her hand touching the firm little mound. Her fingers searched for the button of Kathy's nipple and found it. She pinched gently, rolling the tiny knob between her thumb and finger. Kathy gasped.
"Oooo, Beth! It feels so good!" Kathy moaned.
"Umhmmm!"
For several minutes they stroked and caressed their nipples, drawing soft sighs and moans from each other. Kathy paused and swallowed. Her eyes had dropped to Beth's slit. The girl was stroking her love button in a frenzy. Kathy let her hand drop from guiding Beth's hand over her nipples and let it rest on the younger girl's thigh. Beth looked up at her, her eyes round and wide.
"Kathy?" she moaned softly.
Kathy couldn't answer. Her throat was too dry and her body too ensnared in lust. Her fingers danced slowly over the satin smooth skin of her sister's thigh, getting nearer and nearer the girl's crotch. She touched the back of Beth's hand and the girl jerked. Kathy gently pushed Beth's fingers aside and cautiously touched the slippery hot flesh of her sister's slit. Beth jerked and groaned. Kathy gasped. Her fingers pushed between the fleshy lips and explored the wet warm crevice. Beth was trembling, her breath harsh and rasping.
"Oh, God, Kathy!" Beth gasped. "It feels soooo good!"
Kathy heard the words and felt her own body throb with fire and lust. Her finger found the tiny little knob at the top of the slippery slit and flicked it slowly. Beth shivered and bounced.
Kathy realized the uncomfortable position they were in and paused to push Beth over onto her back and then stretched out beside her. The girl's legs were splayed her robe open completely. Kathy pushed her hand under the elastic waistband of Beth's panties and returned to her stroking. Beth's small hips began to lift and fall in rhythm with her sister's probing fingers.
Kathy felt as if her own slit would burst into flame. It throbbed and itched for contact and relief. She took Beth's wrist and guided the girl's hand to her own crotch. The small fingers rubbed, timidly, unsure of themselves. Kathy moaned and pressed them harder against her cloth-covered mound. As her fingers sliced back and forth through Beth's crevice, she urged the girl to imitate her motions.
Finally, Kathy pulled the crotch of her panties aside and Beth pushed her finger into the waiting wet slit. Kathy groaned and hunched her narrow hips, parting her thighs a little more. Fingers and wet slits slurped softly as they worked each other higher and higher.
Kathy's breathing became ragged and her lips dried. She had a strange craving to suck something. Almost automatically, her head dropped and her lips circled Beth's small rigid nipple. Her tongue flicked across the hard sweet button and Beth moaned her finger stirring harder and faster in Kathy's slit. As if by instinct, Kathy laved and suckled the nipple, her actions drawing her and Beth to an even higher pitch.
"Oh, Kathy, it's… it's…" Beth rasped into her ear. "Oh! Oh! Oh! Oaooannnnnn!"
The smaller girl shuddered under Kathy and her legs clamped around her hand. She stiffened and jerked again. Kathy felt her own release very near. Her breath whistled through her flared nostrils. Her tongue lashed and stabbed at Beth's nipple. She rode the girl's frenzied finger.
"Mmnimmmph!" Kathy gurgled around the small nipple as the bubble burst deep inside her and she shivered and jerked to an absorbing climax.
Kathy pulled her mouth from Beth's nipple and collapsed onto her back. Her mouth open, eyes closed, she rode the waves of intense pleasure, oblivious to the rest of the world. Beth was still trembling through the ebbs of her climax.
Neither girl saw their father as he stood outside the door. His face was twisted in shock. He had entered the house and walked through it to the door just as the two sisters were crashing into their climaxes. He leaned against the door facing and watched. His face showed shock but there was a sudden bulge in his slacks. His numbed mind didn't function for several seconds as he tried to cope with the scene before him. Slowly, the ability to think returned, even though it was foggy thinking. His eyes wandered for a moment over the eleven-year-old and thirteen-year-aid bodies of his daughters. His mind flashed back to Sharon and her expert mouth and his cock throbbed.
As the two girls began to stir, he knew he had to confront them with his presence, but he wasn't sure how to handle it. He stepped into the room and paused. Kathy saw him first. Her eyes snapped wide open and she froze for a second before she realized that she was nearly naked. Beth heard her gasp and looked up. She jerked up to a sitting position, wrapping her robe around her.
"Daddy!" Kathy gasped.
"Don't say anything," he said softly. He pushed the door shut behind him. "Your mother is still asleep."
The two girls sat very still, staring at their father. Kathy had crossed her arms over her naked breasts but hadn't made any other move to cover herself.
"I don't know what to say," he began. "I saw the two of you just as you were finishing…" he trailed off. He stepped around Beth and sat down on the bed. They turned to face him.
"Daddy, was it wrong?" Kathy asked softly. Her eyes fell on his lap and for the first time saw the tell tale bulge. She wasn't sure but she thought that he must have been excited by what he had seen.
"I… I don't know," he mumbled, shaking his head.
Kathy and Beth exchanged quick glances. Both were surprised. This was their father who had always been able to answer their questions, especially when they concerned right and wrong.
