Alex and Natasha were heading down for the weekend to stay with Marina, Natasha’s mother. Natasha hadn’t seen her Mother, step Dad Connor and baby sister Charlotte for a while, so she was looking forward to the weekend.

Alex was keen for other reasons, he had just got a new black Range Rover Vogue and wanted to put it through its paces on the trip down from their home on the other side of New York to The Hamptons.

Natasha relaxed in the passenger seat wearing jeans and a grey top with black pumps. While Alex enjoyed his new toy. They had been married eleven months now and the honeymoon period had slowed down now. They were having sex almost every day when they first got together four years ago. Now it was once a week and if life or work got in the way maybe not even that.

They got there about 7.30 in the evening, Marina and Connor greeted them and they soon settled in.

Charlotte, Natasha’s sister was nineteen and eight years younger than her. She was currently living back at home while on break from college. She favoured her birth Father’s looks and had thick black hair which flowed down her back. Natasha and her mother were both pale and redheads. The girl’s parents split up years ago and Marina had been married to Connor for seven years now.

It was Friday night and Charlie, as she was often affectionately known, was heading out with some friends. She came down dressed in a short cream skirt and an off-the-shoulder black top. Her legs went down to a pair of high-heeled mules with two transparent straps running across her feet.

“You’re not going out that like that, are you?” her mother exclaimed.

“Mum, it’s fine. I’m going to wear a jacket.”

Alex couldn’t help but watch the sexy teenager glide across the floor to fetch her black blazer from the coat mountain hanging off the single hook in the hallway.

“Are you still OK to give me a lift, Connor?” Charlotte asked.

“Can you give me five, I am just finishing off something for work.”

“I can give you a lift, Charlie, if Connor is busy,” Alex called out.

“That would be great, if you don’t mind, Alex?”

“Any excuse to go out in that car of yours,” Natasha added.

They got in and sped off to Charlotte’s rendezvous. Charlotte had been dying to go out for a spin in Alex’s new Range Rover since she heard he had bought it and Alex was happy to show it off. As they drove along, she slipped her feet out of her heels and Alex watched as her toes danced along the dash.

“Sorry, Alex, do you mind?”

“No. I don’t mind.”

Her skirt fell back as she continued to move her feet along the interior. Alex couldn’t help but keep glancing at her perfect legs and red pedicure rubbing on his cream leather.

Charlotte started telling Alex about a guy she had seen a few times. She knew he quite liked her but wasn’t sure if she felt the same. Although he was a good kisser.

“Really, I hope it was just a peck on the cheek,” Alex smiled.

“Well, it was a bit more. I am nineteen, I’ve had sex.”

“I never did anything more than kissing until I was twenty-five.”

“Yeah, Alex!”

Alex didn’t reply and just laughed.

Just then they felt a thud and the car swerved into the road. Alex pulled it into a layby.

“Are you OK?” Alex asked.

“Yes, fine. What happened?”

“We must have hit something.”

Charlotte slipped her heels back on and the pair got out to investigate what had happened.

“Fuck, two flats! I better call the Auto Club,” Alex said observing the damage.

He got out his mobile and dialled recovery.

“It’s going to be forty mins,” he said putting his mobile back in his pocket after the quick explanatory call. “Do you want me to get you a taxi, so you’re not late, Charlie?”

“No, it’s ok, don’t be silly. I’ll wait with you.”

They got back in the car and Alex asked some more questions about the guy she was seeing. Charlotte was getting a bit flirty as she touched Alex’s leg. He couldn’t help but study her perfect body.

“How far do you think it is acceptable for a boy to go?” Charlie asked. “I mean in public, I think this is OK?” she continued.

Charlotte took Alex’s hand and put it along her leg and with her hand over his, she moved it to her knee. Alex was getting aroused feeling her young, smooth bare legs.

“Yes, that is fine,” he exclaimed.

“In private, what sometimes happens is his hand moves further up my leg.” Charlotte moved their hands further to the edge of her skirt.

“Well, I would stop there,” Alex said.

“But I start to feel quite sexual at this point.”

She then guided Alex’s hand up her skirt along her soft thigh.

“I love being stroked here, it gives me goosebumps. It’s the thought of what might happen next!”

She was so sexy and alluring. Alex wanted to stop but the thought of her was making his cock hard. Charlotte opened her legs a bit more and lifted them up. Alex could see her black underwear, she was wearing a small G-string. Charlie moved his fingers to the back of her legs, grazing her arse cheek.

“I like your touch, it’s so delicate, Alex”

Charlotte took her hand off Alex’s. He continued to stroke her inner leg. Alex then ran his hand between her legs, lightly going over her soft silk underwear. Charlotte tilted her head back. She was heavily turned on.

“Please play with me,” she whispered.

Alex moved her G-string to one side and started stroking her pussy and the small amount of neatly trimmed pubic hair. She felt soft and wet. He slipped a finger between her pussy lips and into her warm welcoming hole.

Suddenly bright lights filled the car. Alex quickly pulled his hand away. It seemed the recovery truck had arrived. Alex got out of the car. He was conscious he didn’t want to shake Gerry, the recovery guy’s hand, having Charlie’s juices all over his fingers.

Charlotte also got out making sure her underwear was back in place. She watched Gerry as he replaced the tyres.

“Out for the evening?” Gerry smiled at the pair.

“This is my sister-in-law, I am just giving her a lift.”

“Oh, right.”

The tone in his voice made Alex think that Gerry thought there was something more sordid going on. And there may have been if he hadn’t interrupted.

When Gerry had finished Alex thanked him and he went on his way.

“Well, we should head off,” Alex said, getting back in the Range Rover.

“Do you want to finish what we started?” Charlotte asked.

“It’s a bad idea, Charlotte.”

“No, it’s not. Thirty minutes ago, you were stroking my pussy and I know you were turned on.”

“I am married to your sister, plus I am twelve years older than you,” Alex protested.

Alex was wearing a white shirt and jeans. Charlotte’s hand went over his denim-clad leg and grabbed his penis.

“Don’t you feel turned on Alex?” she said undoing his zipper. His cock pushed through.

“Charlotte, we shouldn’t do this.”

“It could be our secret, Alex.”

She went down to his lap and took his penis in her mouth and started sucking. Her tongue was lapping 'round his rock-hard cock and he watched as her head moved in time with her lips running up and down him. She moved up and they started kissing.

“We should get in the back,” Charlotte suggested as she took off her blazer.

They climbed through onto the back seats. Charlotte’s hand went up her skirt and she pulled her G-string down her legs, letting the garment fall to the floor of the car. Charlotte lay back and lifted up her skirt showing Alex her pussy. Alex looked at her tight hole. Charlotte started playing with herself as Alex could do nothing but stare as her fingers disappeared inside. She pulled them out and rubbed her pussy juice on Alex’s nose.

“You want this, don’t you?”

Alex froze his eyes fixated on this beautiful creature.

He reached over and glided his fingers 'round the outside of her pussy. Then slowly moving between her labia. He put two fingers inside her, feeling her warm, wet slit once more. Charlotte started to breathe heavily as he was rubbing her. Alex quickened up his finger action, two fingers in her while his thumb was rubbing her sensitive clit.

Charlotte moved in and kissed him on the lips, soft at first then heavy, slipping her tongue in.

“You know you want me,” she smiled.

He couldn’t resist her. Then she moved in again for the kill and kissed him again on the lips and round his face. He stroked her bare shoulders, his hands smoothly going over them. He then lifted her top off, pulling it over her head. In turn, she took off Alex’s shirt. They immediately started kissing again.

His hands moved up and held her firm tits, he rubbed his fingers over her hard nipples then moved his kisses down her neck to her chest, taking her bare breasts, one by one in his mouth and sucking her nipples. His hand unzipped her skirt, pulling it down her legs. Charlotte was naked apart from her heels, which she kicked off.

She moved her naked body on Alex’s lap and completely pulled down his jeans. His rock, hard penis rubbed between her naked legs. Charlotte lifted herself over the throbbing spike and teased him by rubbing her arse against his it. Alex felt himself sliding between her cheeks.

“Do you have a condom, Alex?”

“Shit, no!”

“Don’t worry. But promise me, you won’t come inside me.”

“Ok.”

She then moved back and positioned his penis as it pushed into her pussy.

She shrieked as he entered. Her pussy squelched as she slid up and down his cock. He could feel her getting wetter and wetter as she went red in the face. Charlotte came hard and shouted out with a combination of a whisper and shriek. She pulled Alex’s head into her breasts. Alex could taste the sweat between them rolling off her satisfied body.

Alex could feel himself getting close, he pulled out as promised. Cum shot out over her breasts and stomach. He wanked himself to get every drop out on her. He could feel her juices all over his cock. She watched as his warm cum trickled down her flat stomach, filling up her belly button. Alex handed her tissue to clean up.

Charlotte put her skirt and her blazer back on, leaving her black top and G-string discarded on the floor. Alex did up his jeans and put on his shirt. The pair cuddled and kissed. Alex’s hand then wandered inside Charlotte’s blazer feeling her naked chest. After a while, they climbed through to the front. Charlotte put on the rest of her clothes and slipped her feet back into her high heels.

“We should keep this our secret, Alex.”

“Yes, and a one-time thing,” he said feeling remorseful about having sex with Natasha’s sister.

“I should take you to your friends.” Alex started the engine.

“Well, I am not sure I am up for that now.”

“If it’s going to be a one-time thing. We could do it again?” Charlotte said smiling.

“I don’t know.”

“You know you want to,” she said

“Yes! You are beautiful, and I can’t help but want you,” he replied.

“OK then. This time I want you to take me from behind next time and ejaculate over my arse!” she declared.
