Dad gets his wish by pickticket69

“Listen, if I invaded you in anyway…”, he started to say.

“You didn’t”, Katherine turned to face him.

“I mean…you mentioned you and Jess, and I didn’t want to…” Justin tried to explain.

“Look”, Katherine reached out and rested one hand on his thigh. “Jess and I have explored, I’m not going to lie”, she smiled. “But she is as much into guys as she is girls”, Katherine chuckled.

“Oh; I thought maybe you two were…you know”, Justin looked over at her.

“Lover’s?”, she asked. “Look Justin, Jess’s bi-sexual. And me…well I wasn’t sure.” She sighed.

“Wasn’t sure about what?” Justin asked.

“I thought maybe I might be gay.” Justin felt her other hand slide onto his lap as he stared into her eyes. “I’m not; no guy attempted to do that to me…until now.”

Justin shuddered as he felt her fingers deftly unsnap his jeans and begin to draw his zipper down.

“Kat…you don’t have to…” he tried to protest.

“I know I don’t have to”, she dipped her hand through the opening of his boxers. “I want to”, she purred as her hand wrapped around his hardening cock.

“I’ve never done this before”, she husked. “So, tell me what to do.”

His cock was hard as steel. “Put your mouth around the head, and swirl your tongue around it.”, Justin instructed her. He just sat and watched as Katherine’s head lowered between his stomach and the steering wheel. He couldn’t see through the mass of dark hair; and with only the dim porch light, there wasn’t much to see. But God, he could feel it.

Wet warm surrounded the head of his cock, and he felt her tongue slowly making circles.

“Oh Goddddddd”, Justin moaned.

He reached out with both hands and gripped the steering wheel, as he felt his sisters hot mouth slide down his cock. He looked around in fear, God if anyone saw what was happening it could get back to their folks.

“Oh shit…Kat”, he moaned as her mouth began to move up and down. The sound of her sucking filled the cab as she devoured his throbbing dick. “I think you got this!!”

Justin could feel his balls tightening. If this was her first blowjob, he couldn’t imagine what she could do with experience. He moved one hand down and curled his fingers in her dark hair. Glancing over, he was shocked to see Jess standing at the door to the house watching them. There was no way she could miss the bobbing mass of hair in his lap. Jess gave me a thumbs up, and slipped back into the house. He knew then there was only one way this was going to end.

“Oh fuck…Kat…that’s so fucking good.”, He gasped!

Justin felt her mouth come free and her muffled words from his lap.

“Am I doing that good?”, Katherine questioned a little out of breath.

“Keep it up and you’ll make me cum”, he warned her.

“Good”, was her one word reply and then that heat wrapped around him again.

“Oh shit…don’t stop…oh fuck Kat…”, Justin babbled as his nuts tightened until they ached.

“Oh my Goddddddddddddddddd” he moaned as his body jerked; and the first blast of hot cream pumped into her mouth.

He heard her softly gag on the first blast; followed by the sound of her swallowing as he fired off a second and third blast.

“Mmmmmmmmmmmm”, Katherine murmured as he unloaded his balls into her eager mouth.

Justin’s brain spun with sheer pleasure as his sister drank his hot seed. He never came like that. EVER!!! Part of it was the forbidden aspect of Katherine being his sister. And part of it was also how soft and gentle she was.

By the time Katherine lifted her mouth from his softening cock, she had managed to suck out what felt like was every drop of cum his balls had held. He just stared in wonder as she rose back to sitting, a small dribble of white goo trickling from the corner of her mouth.

“Holy shit”, Justin breathed out slowly.

Katherine reached up and used the tip of her finger to swipe at the small glob, popping it into her mouth. She smiled at Justin.

“Now that was hot”, she murmured.

Justin couldn’t move as Katherine opened her door and slid from the truck. He tucked his limp cock back into his jeans as he watched her walk to the door. This was simply going too far, he realized. He needed to rethink this arrangement, but for tonight he just wanted to remember the hottest blowjob of his life.

For the next three days, Justin thought and pondered over where things were going with Katherine. It was a route he had never intended; and one that both troubled and excited him. She made him feel in ways he had never felt before; but the nagging thought this was his sister kept bubbling to the surface. Finally, just when he thought he had worked up the nerve to talk to her; Katherine floored him once again.

Coming home from working second shift, everyone in the house was sleeping and Justin quietly picked his way through the darkness to his room. Closing the door, he flipped on the light and then he stepped to his desk to drop his keys. Sitting on his desk was the hundred dollars he had given Katherine for being his prom date. It was resting on a note.

His heart sank as he picked up the hundred, and then the note. She was calling it off, he thought. No prom… While his dad would be pissed off, he knew she was right. Then he looked down at the note.

‘I want to do this because I choose too, not because you paid me.’

As Katherine’s words sank in, Justin wasn’t sure whether he was scared of what might come next or thrilled his dad would get off his back if it did.

For the next week, his father kept going on and on about the upcoming prom and Justin’s date. Every time he bragged about ‘his boy’ bagging some hot high school girl, Katherine would just stare at him and then shake her head. It was so bad his father gave him money for a tuxedo, and bought him a fresh box of condoms, which he flaunted at the dinner table making Justin blush as Katherine looked on.

On prom night, he was in Jess’s house waiting for Katherine to get ready.

He heard her coming down around the corner of the hall. His first sight was red painted toes in a pair of strapped high heels. As she came closer, his eyes traveled up her calves and lower legs, to the expanse of firm tanned thighs. The hem of her rose dress ended just above mid-thigh, low enough to be proper, but high enough to create the threat if she bent or moved wrong.

By two more steps, he didn’t know which way to look. That firm ass that the skirt flowed over. Or the taut belly clearly visible through the rose lace of her top. It was so sheer; Justin could see the glint of silver from her belly button piercing.

But it was when she got to him, he almost stopped breathing. The rose lace continued up and over the curve of her breasts. The sheerness highlighting the globes of flesh they barely hid; the dress had just enough thickness at the right two spots to hide the caps of breasts, taking the nipples from his view. There was no bra, he realized. The top was tied in a single bow at her neck; and the back, well, there wasn’t one. Bare tanned skin ran the full length down to just barely above the crack of her ass. It was apparent she also had no panties.

“You can breathe now”, Jess’s amused voice sounded in his ear.

“Oh my God”, Justin let out with his held breathe. Katherine looked at him in surprise. “You’re stunning”, he said more softly.

“Thank you”, Katherine gave a demure smile. “Shall we?”, she asked softly.

All through the drive Justin couldn’t tear his eyes from her; he was still in shock at how stunning this tomboy sister he had never noticed was. It didn’t help that the obvious tent in his slacks showed his approval. Katherine said nothing as he kept stealing glances; she just sat quietly with her hands in her lap.

As they entered the dance hall that had been rented, Justin felt like he was on cloud nine; there was no doubt the most beautiful girl here tonight, was on his arm. He had purposely given them an extra half hour so that people would already be present, and their entry would hopefully not be noticed by some; unfortunately, he was wrong.

“Yo Dawg!”, rang out behind them; and Justin felt Katherine stiffen in his arm.

“Hey Reilly”, Justin acknowledged him.

“Your Dad must be a very proud man tonight.”, Reilly offered.

Before Justin could retort Katherine spun on her high heels and faced the young man. “That’s because his Dad knows Justin is going to fuck my brains out tonight”, her sultry voice spoke as she looked at him.

Reilly’s mouth dropped open at her frankness.

Katherine turned back to Justin. “I think it’s time we danced”, she said. Grabbing Justin’s arm, she spouted, “Shall we?”

“Holy fuck”, Justin let out his breath as they moved towards the dance floor.

She turned back to look at Reilly, his mouth was still agape. “You be sure to tell Justin’s dad.”, she yelled.

He wrapped his arms around Kat and pulled her close. It was such a contrast to him; the swiftness and power he had seen in her reaction to Ricky; and the soft feminine form he now held.

Justin reveled in Katherine’s closeness as she never was far from his side. Small touches from her hands, the smell of her hair when they danced; all of it made the evening pass like a swift bolt of lightning. He had lost count of how many dances there had been; both fast and slow; and as the band began to play the midnight lovers song, he knew what he wanted.

“This has been the most perfect night, thank you”, he whispered into her hair.

“Not 100% perfect yet.”, Kat’s voice was a soft murmur.

Justin’s eyebrow raised, “Yet?”, he questioned.

Katherine pulled his face to hers, and her lips ascended to his. Her tongue slipped into his mouth. She felt one of his hands slide lower, all but cupping the cheek of her ass. She knew this was so wrong, but she wanted to stop her dad from pressuring Justin. And she knew he wouldn’t lie. As their lips parted, she looked into his eyes.

“We need to leave” she said softly.

Justin nodded; and the two headed over to gather their things from their table. Katherine was silent as they headed for his truck, Justin wanted to ask what she was thinking, but was terrified of her answer. As he slid into the driver seat, Katherine looked over at him.
