My girlfriend's sister (Closed)

[Orgasmicallyfun]

Matt woke up to the warm glow of the sun hitting his torso. Rolling onto his side he saw the rest of the bed empty and remembered his girlfriend Ashley had work this morning. He was staying over her place because she said her parents were going to be out of town for the weekend. He had been dating Ashley for almost four months now and he always stayed at her place when he could.

Getting up he walked to the bathroom then head back to Ashley's bed, stopping at the mirror real quick. Looking at his athletic 6' body, his brown hair and blue eyes. He was only wearing a pair of boxers because he thought he was home alone. Climbing back into her bed he closed his eyes wondering what he would do until Ashley got home from work.

 

[HottieKatie]

Livvy left the kitchen after having had breakfast. Today she was completely and she planned to do nothing but having a great time.

She hadn't even got dressed, and she planned to be wearing her most comfortable pajamas (a Star Wars themed cropped shirt and knickers) for the whole day.

She turned on the volume on her ipod as she went up the stairs and started singing out loud.

She walked backwards after she passed her sister's boyfriend, Matt. Livvy couldn't remember how many times she had tried to be alone with him, but there were too many. And now there he was. How come Ashley hadn't told her he was there? She should have imagined it, though, as their parents wouldn't be home.

"Hey cutie!" she called him as she entered her sister's room. "Would you like some company?"

She didn't really care if he wanted her there or not, for she was going to stay anyway.

She jumped on the bed next to him.

"So, Ashley won't be back until lunch time. What do you think we could do until then?"

She had been flirting with him since the day they met, but he stood strong. That would surely change some time soon.

 

[Orgasmicallyfun]

Matt was on the verge of falling back to sleep then he heard a voice call out to him. He was startled a little and opened his eyes to see Ashley's sister, Livvy standing there barely clothed as well. He noticed her star wars shirt, well if you would call it a shirt. Any shorter and her breasts would be hanging out. Then he realized she only had that shirt and a pair panties on as well. He pulled the cover over him since he was only in his boxers.

"Hey Livvy" Matt said. He wondered why she was always flirting with him. He was dating her sister but it seemed she didn't care. He never said anything to Ashley because he didn't want them to fight or anything. "Uhh if you want. I was actually gonna take a nap." He always tried avoiding Livvy when Ashley wasn't around because then that left her free to flirt as much as she wanted.

"How do you think Ashley would feel about you being in her bed with me and you being barely clothed on top of that?" He asked as he tried thinking of a way out of here but he couldn't think of much.

 

[HottieKatie]

Take a nap? What a bore! No doubt he was dating her sister, they were both so dull!

When he talked about her sister she just couldn't help to start laughing.

"Ashley? And who would tell her? I surely wouldn't. And you don't look like a snitch either."

She was amazed at how silent he could be. At that stage, all of Ashley's precious boyfriends had already told her about her 'sister's misbehaviour'. But Matt kept it all for himself.

"Are you going to spend the next 5 hours sleeping? What are you, 60 years old?", she said sitting up on the bed.

He was a tough one, but she was going to win. She always did.

Before he could do anything, she pulled the sheets he was covering with.

"Get out of bed, don't be lazy!"

And there he was, almost naked.

Livvy kept looking at him.

"Well, yeah, Ashley has good taste..."

 

[Orgasmicallyfun]

Matt wouldn't dare tell Ashley about how her sister behaved towards him. It would end up causing so many repercussions and he did not want that. 'She really isn't gonna leave me alone is she' Matt thought to himself as the covers were yanked off his body so he was laying there in just his boxers. He laid there frozen like a deer in the headlights as she mentioned how her sister has good taste.

After a few seconds he snapped out of the state he was in and sat up leaning his head against the headboard of the bed. "What do you have in mind then?" He asked figuring he might as well find out what it was she wanted to do. Looks like he was going to be spending the time Ashley was at work with her sister.

 

[HottieKatie]

Livvy couldn't believe how easily he had yielded, after all.

She wondered whether he would really be ready for what she had in mind.

"Well," she continued getting closer to him again, "they say the best way to start the day it pumping your immune system with half and hour of cardiovascular exercise... Do you fancy?"

She then started running her finger up and down his thigh, her eyes peeking at his boxers to see if it caused some movement down there.

 

[Orgasmicallyfun]

Matt wouldn't mind going for a run or something so he nodded and said "Sure I could use a workout." It was then when she started running her finger along his thigh. It was then when he realized she met something other than a run. He tried playing stupid while trying to control himself and keep his boxers from tenting in front of her. " What did you have in mind. A run?" He was trying to think of an exit plan out of this situation.

 

[HottieKatie]

Livvy found him so amusing. He was playing the naive boy. He knew exactly what he wanted, she could see it in his body movements. But he wouldn't admit it.

"A run? Not at all sweetie," she kept running her finger along his thigh. "I am thinking about indoors exercise."

At that point she went upwards, running her finger up to his hip bone, taking the boxer leg up with her finger. She wanted to touch his dick but thought about waiting for a little longer, wanting to know what he'd do when he finally accepted she was going to fuck him.

 

[Orgasmicallyfun]

Matt couldn't stop his cock from starting to stiffen as she ran her finger under his boxers up to his hip bone. It was almost impossible to hide from her. He tried thinking of a way out of it but knew this time she wasn't going to stop until she got what she wanted. He tried backing up more but only pushed against the headboard of Ashley's bed. "What are you doing Livvy? I'm sure Ashley wouldn't approve of the type of exercise I think you have in mind." Matt's cock was now semi erect and the long thick outline could be seen through the thin fabric of his boxers. Matt knew he was in trouble.

 

[HottieKatie]

Livvy couldn't believe the guy. He surely wanted her, but his resistance was so bad. He probably didn't really know what he wanted.

With other Ashley's boys she had got only two clear reactions. The less usual, the guy escaped her and wouldn't stay near her -- it had happened only once. But usually the guys wanted what she offered them, and once they decided, then went fully for it.

But Matt was different. Either he was afraid of Ashley or afraid of Livvy. She guessed it would be her sister, as Livvy was such an angelic girl... She smirked at the thought.

"Do you think I need my sister's approval? I can do whatever I want to," she finally said, as she went forward.

Livvy thought it was time for the last try. He was already stiff and she knew it was now or never.

She jumped on him and quickly straddled him, sitting on his slight bulge, her hands on either side of his head.

"So, what's it gonna be? You want to have some fun with me or not?"

She started rubbing her pubis a little on his cock. That should be the last straw to make him yield. But he still had the chance to get away. He only had to push her aside and leave the room.

"It's ok if you don't want to... I wouldn't want to force you..." she kept talking as she went on rubbing him, feeling his cock twitch a little between her legs.

 

[Orgasmicallyfun]

Matt knew he was done when Livvy straddled his lap. Her breasts just inches from his face. His cock now rock solid as she started moving her hips against him. "You are very persistent aren't you Livvy?" Matt asked as he placed his hands on her hips but instead of tossing her off of him, Matt pulled her down onto his lap more. "You feel that?" He asked referring to his big hard cock which he was certain she could feel through the thin fabric of their clothes.

"I think you know what the answer to your question is Livvy." Matt said thinking only for a split second how he could do this to Ashley, but then it was gone and he was thinking about the sexy petite teen grinding on his lap.

 

[HottieKatie]

She knew she would convince him. She knew how to use her body too well. And he was easy. As any man. Once their gun was loaded, they couldn't stop it. And it was so easy.

"You feel that?" she returned his question, pressing down her hips. He would surely feel her warm and slightly wet panties through his boxers.

"I always get what I want," she said as she started moving upon him more insistently. "And right now I want to fuck you on my sister's bed."

It would either be a big turn on for him or make his conscience raise.

"Wouldn't it be fun? Staining her pure white sheets with our sweat and juices?"

Ashley was such a good girl. Livvy wondered how many of the dirty and nasty things she planned to do with Matt had her sister tried with him. Probably none.

 

[Orgasmicallyfun]

Matt felt the heat coming from Livvy's pussy and it only turned him on more. His cock throbbing against her pussy. When she said she wanted to fuck him on her sisters bed right now he didn't say nothing at first. Him and Ashley haven't had sex in almost a month now, and it would be with her sister. Better than some random girl off the street. "Okay you win Livvy, I'm just gonna be helping her sister get what she wants so I don't see any problem with it. You know we haven't had sex in almost a month now? And every time we do she always makes me wear a condom."

 

[HottieKatie]

"Of course she does, you might have been sticking your cartridge somewhere else---"

Livvy felt a bit sad for Matt. A month without fucking? That wasn't fair.

"Poor boy, a month without shooting. Ashley is such a boring girl. I wonder now why you're still with her."

She kept rubbing her thighs against his, but now a bit slower. If he hadn't had sex for long, he might be too quick. And she didn't want that. Also, now that she had his attention, she wanted him to beg her. That was her game. First they didn't want her at all, but then they would do whatever she wanted from them.

"Is she so good at fucking to keep you waiting for a month?"

 

[Orgasmicallyfun]

Hearing what she was saying made him crave sex even more then he already was. There was no way he was going to be able to say no to Livvy at this point. The warmth from her pussy feeling so good as she continued grinding on him. His massive cock continuing to throb against her, he was sure she could feel that through the thin layer of clothes that separated their flesh.

"I know a whole month... I am so backed up" He said softly before letting out a soft sigh. "No she actually isn't that good at all, she just lays there and makes me do all the work. I respect her too much to go out and cheat on her, but with her sister that is okay right?" He asked looking into Livvy's eyes.

 

[HottieKatie]

"Keeping it in the family," she reassured him.

Matt seemed really worried about being cheating to her sister. Livvy didn't care about that. She just wanted to have a good fuck, and Matt was the closest guy around. If he needed her reassurance, he'd have it.

"I'll be Ashley's darker side, if it makes you feel better. Close you eyes," she asked him, as she got up from him.

Quickly she went to her sisters closet, picked one of her shirts and a skirt and changed her clothes. Livvy was a bit bustier than Ashley so her sister's shirt was too tight on her. Livvy's erected nipples protruded a bit through the white fabric and the central button seemed about to shoot out.

Livvy went back to Matt, resuming her position on top of him.

"Say hello to an improved Ashley. Let me show you how wicked girls like to play," she finished with a smirk, as she grabbed his hands and placed them on her ass checks, under her sister's skirt.

 

[Orgasmicallyfun]

"Oh god" Matt said as he opened his eyes back up to see Livvy in Ashley's clothes. Then she grabbed his hands and brought them to her ass under her skirt. He felt her nice round ass in his hands and could feel the difference between hers and her sisters. Livvy's ass was a little bigger and more lush, something he loved. Now since she was pretending to be Ashley it made this a little easier on his mind.

"Such a new side to you Ashley. I am going to love this side to you I can already tell" His hands started to squeeze and caress Livvy's ass. His cock aching to be released from the confines of his shorts.

 

[HottieKatie]

Livvy was still amazed at how easily she had convinced him. If it was true that he hadn't had sex in a month, she could easily understood why.

She felt him hugging her ass like he had never touched one in ages. Ashley's ass was quite small, compared to hers, so he would probably wouldn't have much flesh to hold on to.

"Of course you like it, puppy, as I come directly out of your wildest dreams."

Livvy decided it was time to release his aching member and moved aside a moment. She grabbed his shorts, pulling them down to his knees.

"And what do we have here? A little person wanting to play!"

Livvy didn't think twice and run her tongue base to tip, just once. She felt it shiver and twitch. Matt groaned loudly. Livvy wondered if he had ever groaned like that with Ashley.

She stopped and looked at him, waiting for a follow up from him. She wanted him to need her, beg her.

 

[Orgasmicallyfun]

Matt watched as Livvy got off of his lap and pulled his boxers down, releasing his massive member from its confinement. He saw the look of amazement on her face from how big he was. Pretty much as soon as his boxers were off she ran her moist tongue from the base to the tip making Matt groan out and grip the sheets on the bed. Then she stopped and was just looking at him. "Why did you stop? I need this... it's been so long for me Livvy"

 

[HottieKatie]

"Livvy?" She shouted, as she slightly slapped him in the face. "Why would you cry out my little sister's name?"

She wonder whether her sister would have reacted like that is Matt had spoken her name while they were making out. Probably she would have started crying or something. She was quite delicate. But Livvy was creating a new Ashley for Matt. A naughty strong Ashley.

"If you want me to go on, you'll have to ask for my forgiveness," she went on while she moved away and sat comfortably on the bed. "That is a serious offence, don't think I'll forgive you so easily, you'll have to make up for it."

 

[Orgasmicallyfun]

Matt was shocked by the slap he received from Livvy and once she started talking he noticed how she was seriously pretending to be Ashley. The petite teen moved away from him slightly and he thought she was going to leave but she was still playing the role of Ashley.

"I'm sorry Ashley I don't know what came over me. It won't happen again! I'll do anything to make this better" Matt said. He was roleplaying with Livvy and he had to admit it was very sexy. "Just tell me what I can do to fix this Ashley."

 

[HottieKatie]

"Oh, Matt, are you really so sorry? Or you'd like to fuck my sister?" Livvy kept teasing him. She loved being so mischievous.

Livvy parted her legs and spread them open on the bed while she leant on her stretched arms behind her back.

"What would you be willing to do to fix your big mistake?"

 

[Orgasmicallyfun]

"Ashley you know you're the only one who gets this big cock" He said as his cock twitched as he looked at Livvy's pantie covered pussy that he found himself wanting more and more. He never had this kind of fun with Ashley, nothing close to it in a long time. "Anything at all Ashley. You name it and I'll do it baby."

 

[HottieKatie]

"But it is not you big cock I want right now," Livvy continued as she took off her panties. "It's your tongue."

With that, Livvy dragged her butt on the bed, to get her now naked pussy closer to Matt.
His cock would have to wait.
Livvy offered Matt her neatly shaven mound, wondering whether Ashley would keep it like that too.

 

[Orgasmicallyfun]

When Livvy peeled her panties off and moved closer to Matt his eyes were glued to her neatly shaven pink teen pussy and Matt wanted it so badly. She got so close to him and told him how she wanted his tongue. She was pretending to be Ashley but he was about to eat out his girlfriends little sister. "I did say anything to fix my mistakes baby" He said as he moved towards Livvy and his head went between her legs and his hands running along her smooth inner thighs stopping just inches from her beautiful pussy.

He hesitated for a second but he was so turned on and needed this so bad since him and Ashley haven't had sex in so long. He could smell her sweet scent and his lips parted and he ran his tongue up along her pink silky lips instantly tasting her sweet taste and was hooked instantly and continued lapping his tongue up and down her pussy while his big hands caressed her thighs and lower stomach.
