Standing, Jody straightened her clothing and kissed him lightly on the lips. 'Better, Tim?'
'Thank you, Sis… God, but I love that hot mouth of yours!'
She giggled and squeezed his prick tightly. 'Thank Dad… he's the one who taught me to use it.' She stepped back from him. 'We'd better get back before Dan misses us… come on!'
Trina felt her orgasm rising as Trish fingerfucked her lewdly. She gasped as the wave of sensation washed over her and she felt her juices flowing heavily. 'Ohhhhh… Ughhhhnnnn…' she moaned as Trish kissed her passionately.
Trish felt her sister cuming and she forced her tongue into her mouth. As Trina shuddered, Trish pressed her body close and shared the sensation. It was always like that for Trish and Trina; being identical twins, they often experienced dual emotions and sex was one of the stronger they shared.
Standing on the patio a dozen yards away, Dan Gibson blinked as his eyes became accustomed to the darkness. He held his drink poised an inch from his mouth as Trina gasped loudly. He saw the twin sisters embracing in the darkness of the back yard and his prick twitched against his thigh.
Quietly, Dan moved off the patio to stand beside the large potted palms. He peered into the darkness as the girls kissed passionately. At first, Dan could not distinguish which twin was who, but as he looked on, he saw the differences in their dress.
Trying to tell the girls apart had always been a chore for Dan. Now, as he looked on, he felt his pulse racing madly as Trish raised her hand and her sister licked her fingers. Rubbing the growing bulge in his trousers, he heard them whispering to each other.
'God, you always make me cum so good, Trish!' Trina told her sister and kissed her again.
Trish ran her hand over her sister's tits and felt the flesh quiver. 'If I had a prick, I'd make you cum until you couldn't stand it!'
'Oh, no… no prick could do for me what you do!' Trina protested, then giggled. 'But it would be nice – no one would suspect us of fucking, would they?'
Trish laughed too. 'Did you understand what they said?'
'Uh-huh… freaky, isn't it!' Trina replied.
'I think it's beautiful… and I think it's time we let him know that we know…'
'Oh, Trish, do you think we should?'
'Why not? What's good for the goose…'
Dan moved back onto the patio as the girls turned his way. His prick throbbed painfully against his leg as he saw them coming. He hoped I they wouldn't see it in the darkness. He did not fully understand what the girl's had been talking about, but he understood what he had seen them doing. His mind reeled at the thought of fucking one or both of his nieces, but the thought was dispelled as he heard his wife call out for him.
Inside, Tim Hogan glanced up as his daughters entered the room. He had been drinking since early evening and the party his sister was having had turned out to be a boring obligation rather than the festive occasion she had promised. Still, Tim was satisfied. Jody had sucked his prick and that would hold him until tomorrow.
'Dad… do you think we could go now?' Trish asked as she and Trina crossed the smoke-filled room.
Tim glanced at his watch and caught his sister's eye as he replied, 'Come on, it's still early… you wouldn't want to disappoint your Aunt Jody, would you?'
Trish leaned close to her father and whispered in his ear. 'Jody's parties are a drag for us, and you know it. That's why you didn't make Michael come to this one!'
Tim smiled as he thought about his old son begging off at the last minute. He looked about the room and sighed; he saw the widow Thelma Garrison smiling at him and he knew that if he stayed until the other guests departed, she would ask him to drive her home. Of course, he could always drive them home, then come back – Thelma was obviously on the move…
'S'matter?' Dan asked as he walked up and slipped his arms around the twins' waists.
'Jody's parties are a drag… quote the twins,' Tim said, winking at his brother-in-law. 'Not enough teenaged boys to suit them.'
'No teenaged boys… that's the problem!' Trish said. She felt her uncle's hand tighten on her trim waist.
Dan smiled. 'What the hell, Tim… Jody just informed me the fish have drunk all the scotch… want me to drive them home? I've gotta go out anyway.'
Tim glanced at Thelma again. The attractive brunette licked her lips and returned his gaze. His eyes ran to the full flare of her hips and he nodded. 'Ah, yeah… why not. You girls do want to go, don't you?'
Trish and Trina exchanged a knowing glance and turned to their uncle. 'We'll get our sweaters,' Trina said.
In the hallway, Trish turned to her sister.
'Wanna have some fun with Uncle Dan?'
Trina felt a rush of excitement. She knew the kind of 'fun' Trish was thinking of and she nodded.
The girls were waiting for Dan in the driveway. They climbed into the car, and Trish slid across the wide front seat as her uncle started the car. As they pulled out of the drive, Trish moved closer to her uncle. Her hand lay innocently on his thigh.
Dan glanced down at the girl's hand. He swallowed thickly and glanced toward Trina.
'Ah, I guess grownup parties are a drag for you girls.'
Moving her hand up an inch, Trish shrugged. 'They wouldn't be if they were really grownup,' she replied mysteriously.
Dan's prick twitched as he felt the girl's warm hand on his thigh. 'And what's 'grownup' mean to you?'
'Oh, you know…' Trish said, inching her hand higher toward his crotch.
Dan stiffened as he felt the girl's fingers touch the head of his throbbing cock. He couldn't be sure whether it was accidental or intentional, and his heart beat heavily as he steered the car through the darkened residential streets.
'No… I really don't know…' he said laughing nervously.
'Tell him, Trina…' Trish said, moving her hand over his pulsing cock and squeezing it gently.
'You know, Uncle Dan, grownup parties are kind of sexually oriented – swapping, dirty movies and that sort of thing.'
Trish closed her hand about his throbbing cock, suppressing a giggle as she felt him stiffen. 'You agree, don't you?'
'Ah… Jeez… what do you kids know about things like that?' he asked, feeling the sweat break on his upper lip.
Turning to him, Trish reached over and pulled down the zipper of his pants. 'Oh, we know lots of things, Uncle Dan.'
Dan could not believe it was happening to him. He looked down in amazement as Trish freed his twitching prick. As her warm hand closed about his aching member, he swerved to miss a parked car. 'Trish… For God's sake, what're you doing?'
'Just what you want me to do, Uncle Dan…' she said huskily as she massaged the length of his prick.
'But…'
'Don't you like to have your prick played with?' Trina asked from across the seat.
'I… that is… Good Lord!'
'Eighteen, Uncle Dan… and we know all about sex.' Trish told him, then sat back as she let go of his prick. 'Of course, if you'd rather I didn't…'
'I didn't say that!' he blurted out.
Trish made a clucking sound with her tongue and sighed. 'You grownups never seem to know what you want.'
Dan sat in agonizing silence. He wanted the twins – one or both – so bad he could taste it, but Trish's statement had left him without a response. Slowing, Dan turned the corner and pulled into the driveway. 'Are… are you gonna leave me like this?'
'Well… I suppose that would be cruel, wouldn't it, Trina?'
'I guess… after all, he is our uncle…' the other twin said, glancing toward the house.
'Michael's probably in bed asleep… you wanna come in for a minute, Uncle Dan?'
'God, yes!' he exclaimed, stuffing his prick into his pants.
