Screwing Sister's Boyfriend

[xxerikamariexx]

Erika never had any luck with her boyfriends. They usually turned out to be total pricks. She woke up one morning, annoyed because she fought with her boyfriend the night before. She decided to get into the shower and if her boyfriend came to his sense, he'd at least come back or call. Right now Erika was too annoyed with him to care. She stripped down and got into the shower, letting the hot water hit her beautiful body. She heard someone enter the bathroom.

"Matt? You came back?" She asked, assuming it would be her boyfriend Matt. But to her surprise, it was her sister Jenny's boyfriend, Mike, who had come into the bathroom.

This was going to be interesting for both sides.

ooc: I've been away for awhile so I'd like to start this again. Send me a sample PM if you're interested.

It was a short drive to her house from the gym. Mark walked up to the door and rang the bell. He waited and no answer came and rang again and still no one came. He checked the text he wrote was sent 'I'm on my way babe. Can I use your shower?' He often snuck into her room at nights when her parents were in and decided to use that entrance.

He walked to the side of the house and climbed up to her window. Lucky for him it was out of view from any prying eyes and it was rarely ever locked. He jumped in and closed the window behind him then walked out of her room and quietly walked towards the bathroom. The sounds of the water running coming from the bathroom brought a smile to his face. Her parents were probably still at work and her sister should be with her boyfriend around this time.

He opened the door and heard a voice callout to him. "I'm here babe." He undressed and placed his clean clothes on the counter. The silhouette of her sexy figure was visible on the shower curtain. He tiptoed into the shower behind her and grabbed her by the waist, pulled her in close to him and placed his head on her shoulder. "I see you got my text baby." He chuckled and began to kiss her neck. His hands roamed up her stomach and cupped her breasts. Immediately fear ran through his entire body. Mark had felt his girlfriends breasts many times, he quickly moved his hands away and stepped back, these where not her breasts and this was not his girlfriend. "Erika!" He yelped. "Oh my god, Erika... I'm sorry I had no idea." He grabbed the curtain and covered himself, looking at her in awe and shock.

 

[xxerikamariexx]

Erika was in a pretty shit mood; Matt had been a total prick to her this morning but in the back of her mind, she hoped that her boyfriend came back to the house to make up for and apologize for the way he had acted this morning. As Erika let the warm water drip down her naked body to relieve some of the stress she felt, she felt kisses at the side of her neck from behind. They were soft, sensual kisses..kisses she wasn't used to feeling. She closed her eyes, moaning a little at how it felt. She soon felt those same pair of hands over her stomach, cupping her heavy, rounded breasts. Erika felt something poking her wet, rounded ass. "Mmm, so hard." She whispered, thinking her boyfriend had joined her in the shower.

Mark was dating Erika's little sister, Jenny. Jenny was basically a nerd and a prude as well. Erika loved her sister to the end of the earth but even Erika was shocked that Jenny had a boyfriend. Erika was horrified when she turned around, knowing that Mark was the one who had her hands over her a minute before. She nipples were rock hard from the touching but also from the water of the shower.

"Mark! Oh my god!" She exclaimed, she couldn't even cover herself up because Mark was covering himself with the shower curtain. She bit her lip, not even what to do at this point. This was Jenny's boyfriend but god damn if Mark wasn't sexy.

 

[SynysterBat]

Mark continued staring in disbelief as the water continued pouring down Erika's amazingly fit body. His jaw practically hit the floor as he got a better view of her generously proportioned breasts, the now hard nipples poking out towards him, begging for some attention. "Wow." The word escaped his lips without him noticing he'd said anything, his cock pitching a tent with the help of the curtain spoke louder then any word that escaped his lips could right now.

Mark and Jenny had been together for about a year now and he loved her more then was humanly possible. They'd been intimate many times but looking at Erika, her sisters body he couldn't believe they were even related. Without realizing it, he'd let the curtain go and Erika now had perfect view of everything he had to offer. "Oh my god Erika I'm so sorry." He cupped his hands and pleaded to her. "Please don't tell Jenny anything about this." He knew she loved Jenny as much as he did, maybe more then him and something like this might hurt her. "I will do anything just please don't tell her please." With his hands still cupped and his private area exposed he was glad no one else was home to risk getting caught in this position.

Erika knew if Jenny found out about this, she would flip beyond belief. She knew Jenny and Jenny would think Erika was trying to sex up her boyfriend. Erika had a smoking hot body, rounded breasts and a thick, glorious ass. She had no problem getting guys, the only problem was the recent guy she was with was nothing but a prick. Erika brushed her wet hair from her face, her body cold since the once warm water now turned cold. Her nipples were hard from the cool air. In the back of her mind, she couldn't help but notice the smoking hot body that Mark had. It was evident that he worked out.

"I'm not going to tell Jenny. She would flip the fuck out." She said, knowing her sister very well. Erika knew it was wrong to feel turned on in this moment but Mark was very hot. And the way he cupped her large, soft breasts was very hot. And she also remembered the way his hard manhood had poked her ass.

Erika let her eyes drift downward for a second and she couldn't help but notice how Mark's cock was standing at full attention.

 

[SynysterBat]

Mark breathed a sigh of relief knowing Erika would also keep this little incident a secret between the two of them. "Thank you." He shut his eyes and took in a deep breathe and exhaled slowly trying to calm his speeding heartbeat down. "You have no idea how much that means to me." He opened his eyes and they slowly moved down her large mounds, heaving with every breathe she took, his eyes moved down her flat stomach to her shaved pubic area and bit his lip. It has been so long since he's one neatly trimmed as Erika had hers. Her hips showed the signs of the perfectly shaped ass she had behind her, his penis jerked and twitched instinctively at the view and thought of the perfectly rounded bottom.

"I'm sorry I should probably get out of here and let you get back to your business." He'd completely forgotten the inappropriate situation they were in. "Or maybe you'd like me to help you out a bit with the washing." He said jokingly. His not so little guy twitched again, remembering how her glorious breasts felt in his hands as he cupped them thinking they were his girlfriends. He waited for her answer, whether she took it as a serious proposal or not, the image of her wet naked body would definitely come in handy later on and the longer he looked the better the image would be in his mind.

 

[xxerikamariexx]

Erika knew her way around the bedroom, there was no denying that at all. She had a couple of boyfriends in her past but her most recent one was nothing but a prick. She figured that's why she had enjoyed Mark's touching so much. Mark had strong, yet gentle hands. The way he took hold of her rounded globes was enough to make her shudder with excitement. Her body was dripping wet from the shower, her nipples hard as rocks.

She couldn't believe how hard his manhood was. Her boyfriend, Matt, was pretty good in size and she couldn't help but notice just how thick and how he stood at attention. "Maybe a little bit. Seems to be I can't reach my lower back." She said in an almost whisper. She was half daring him, wanting to see if he'd actually help or if he'd bolt out of the shower.

 

[SynysterBat]

Mark knew about Erika's boyfriend and he knew they argued often for one reason or another, he tried to ignore it as often as he could to not get involved but sometimes it was just impossible. Matt was an asshole, he knew that just by looking at him and looking at Erika right now he wondered why he was such an asshole when he had this goddess with that body all to himself.

He gulped and bit his lip, his eyes opened wider hearing her response to his offer. "Umm great, yeah I can take care of that for you." He walked closer to her, grabbed her by the shoulder and pulled her towards him and her body back under the water. "Ok I'll just get to work then." He grabbed the bottle of body wash and squirted some on his hands. "Ok then, are you sure about this?" He asked regretting it and hoping she didn't take it back.

Before she could respond, he lathered the body wash on his hands and wrapped his arms around her and began to wash her lower back. Her breasts so big just wrapping his arms around her to wash her lower back and they were already pressed against his chest. "Oh wow." He breathed heavily, enjoying the feeling of her hard nipples pressed against him. "They umm.. They feel so good." He muttered rubbing the body wash into her skin. The head of his manhood was pressed against her. It jerked a bit from the feeling of her wet skin, the fact that what they were doing was so wrong but felt so good, and risk of getting caught. He groaned quietly as he continued to wash her.

 

[xxerikamariexx]

Erika was surprised Mark had agreed to wash her like this. They were intimately close and if Jenny ever knew, she'd flip a lid. But Erika figured that what Jenny didn't know wouldn't hurt her. And this was just a little fun between two people. Erika had always been big breasts, that's why a lot of the guys had a thing for her. Her boyfriend, Matt, wasn't into her breasts...hell, sometimes she wasn't even sure if he was into her.

Erika felt Mark massaging the soap into her lower back and she could feel his manhood poking her. It was so hard and firm. She bit her lip, trying not to moan. Her rounded globes were dripping wet, nipples hard, pressed up against his hard chest. He had a killer body; Jenny was a nice girl but Erika knew Jenny had no idea how to please a man like Mark who had such a good body.

"Mark..." She whimpered out, barely...feeling so good.

 

[SynysterBat]

Mark was loving the feeling of her bare skin, her hard nipples against his chest, his hand sneakily moving down her back to cop a feel of her tight ass, and the look on her face as he continued to wash her and his cock up against her pubic bone. "Erika..." He responded to her whimper with a whimper of his own. She seemed to be enjoying this almost as much as he was and he loved that.

He grabbed her ass and pulled her against him. "I have a serious question Erika." He whispered looking her in the eyes. "Is Matt secretly gay?" He asked with a serious look on his face. "You have a smoking body. If I was your boyfriend I'd be all over you every hour of everyday all the time." He chuckled and bit his lip as his hands squeezed her firm, tight ass. Jenny had a nice body too but compared to her sisters... Well there was no comparing the two. He groaned quietly, as a quick image of the two together popped into his mind. He moved his hands up her waist and hooked them around her shoulders pulling her closer to him.

 

[xxerikamariexx]

She knew it was wrong...she knew she was probably going to hell for feeling this way but god help her, she was incredibly turned on. Sure, she had a boyfriend. But Matt wasn't much of a boyfriend and sex...that was basic at best. Lately Matt would just lay on his back and expect me to fuck him. Mark's dick felt so hard poking her...like a true man. Erika found herself a little jealous of Jenny right now, knowing Jenny had him...all of his big, manhood.

Erika rounded, glorious breasts were pressed up against Mark's chest, her hardened nipples poking him just a little. She gasped as Mark grabbed her ass. She had a soft, round ass. "He's not...he's just a prick." She whispered. "Thank you for that." She said quietly. She closed her eyes, her eyes almost rolling to the back of her head as she felt Mark poking her with his cock.

She felt her womanhood beginning to ache with wetness. It was wrong on about ten different levels but Mark was exciting her more than her own boyfriend ever had.

 

[SynysterBat]

Oh god, Jenny please forgive me for this... If you ever find out. Mark thought to himself. His hands roaming the backside of her body now, his still soapy hands covering most of her back in the bubbly soap. "No problem, thank you for giving me this once in a lifetime opportunity." He smiled as his hands moved down to her ass again and gave it a squeeze explaining to her what he meant by once in a lifetime opportunity. "And I'm sorry, I was just curious." He knew now was not the time to be bringing up current boyfriend an girlfriends.

Erika's hot wet body now pressed tightly against him felt like heaven on earth. Mark lost control that second and without thinking about it he cupped the bottom of her ass and picked her up. He began to kiss her neck and quietly moan against her skin. She couldn't be any closer to him now if they tried, and she felt better then he could have imagined. He didn't know if the arousal of all this was giving him more strength or all the days at the gym were finally paying off but right now Erika felt light as a feather. He held her up with one arm and moved the other up her side and cupped one of her enormous jugs.

"Mmm Erika." He moaned and moved his kisses from her neck down to her breasts. With the one arm holding her up he used his other hand to bring her breast up to his lips and gently suckled on her rock hard nipple. "Mmm..." He moaned with the nipple in his mouth sending a shiver through his body.

 

[xxerikamariexx]

Erika was pretty certain that she was going to sister hell. She loved Jenny dearly but she was a woman with needs and by god almighty Mark was there. Mark was charming, good looking and hell, his manhood spoke for itself. It was evident Jenny wasn't doing a good job of pleasing him because if she was, Mark wouldn't be in the shower with her. And to push matters, Erika wasn't exactly thrilled with her boyfriend Matt. Matt had been the definition of a prick lately and fucking....that was almost non existent. Matt basically laid on his back side while Erika fucked him.

Erika's body was cold, the once warm water now turning cool. But she couldn't deny that being so close to a manly body had her turned on, despite the fact that Mark was indeed Jenny's boyfriend. Erika watched in complete and utter awe as Mark took hold of her luscious breasts and she was even more shocked when he wrapped his mouth around her hardened nipple.

"Mark.." She groaned, her eyes almost rolling to the back of her head. Her fingers toyed with his wet hair as she felt her body shiver in pleasure.

 

[SynysterBat]

Mark could feel the water turning from its initial warm to a cold that sent goosebumps down his arms and made his teeth chatter. He paused from sucking and licking her nipples and looked up at her. He loved the feeling of her hands running through his hair. Still holding on to her breast with one hand and playing with her erect nipple he talked in a breathy voice. "Maybe we should get out of here before we catch a cold?"

Without ever putting her down he released her perfectly rounded globe, letting it fall down between them, softly slapping him on the chest. He giggled and reached behind her to shut the water off. He then wrapped his arm around her waist, stepped out of the shower and pushed her against the door. Mark looked into her eyes and kissed her lips passionately, he kisse her as if his life depended on it. "Mmm." He moaned against her lips.

 

[xxerikamariexx]

She couldn't believe they were doing this. Jenny was her sister but Mark was undeniably hot. And if Jenny was satisfying Mark the way she should, he would not be here. She stepped out of the shower, shutting off the water because it was causing her to shiver. But in a matter of moments, Mark had her pushed up against the bathroom door. She pushed the lock button in, not wanting to be interrupted in case anyone came home. She moaned against his lips, kissing him hard...almost possessively.

She wrapped her hand around his manhood that was between them and began stroking it with one hand. It felt wonderful in her hands and judging by how it felt, he was much bigger and harder that Matt ever could be. She let her tongue toy with his in his mouth while her hand enjoyed feeling his hard cock. She pressed her wet body up against his.

How could something that felt so good be so wrong?

 

[SynysterBat]

Mark groaned as Erika wrapped her hand around his rock hard manhood and began to stroke it. Sex with jenny was good but he'd never been as aroused with her as he was right now with her sister Erika. He loved Jenny but this was the hardest he'd ever been. He used his tongue to toy with hers back, his hand travelled around her waist, brushed against her hand as she stroked him and placed it over her womanhood. His cock throbbed in her hand and his hand rubbed the outside of her womanhood's lips.

He moved away from her lips and looked at her and pleaded. "Erika..." He talked breathing heavily. "Could you... Could you please suck me?" So far everything about Erika was amazing and he had to see how amazing everything else about her could be. With his fingers he continued rubbing her lips, she was so wet from the shower he couldn't tell if it was water or her own juices dripping from her down to his finger tips.

 

[xxerikamariexx]

Erika loved her sister beyond words but Mark was so very good looking. And she was so turned on at this point there was no way she'd stop now. Besides, what Jenny didn't know wouldn't hurt her. Erika's boyfriend, Matt, was a total prick so Erika didn't feel guilty in the least for messing around with Mark like this. Erika's body was cold from the shower, causing her nipples to harden completely. She heard Mark's moan and it only turned her on more. Never did she think they'd mess around like this but she figured they could be of help to each other.

Mark didn't have to ask her twice. She got down on her knees on the mat in the bathroom. First, she stroked his cock, wanting it to be fully hard before she took it in her mouth. She leaned her mouth down, wrapping her soft lips around the top of his cock. She softly began to suck, her tongue flicking over the tip, sucking on the head as if it were her favorite flavor of a lollipop.

 

[SynysterBat]

Mark let out a low groan as erika stroked his cock to full hardness. "Oh Erika." He whispered and moved both his hands to the back of her head and grabbed a handful of her hair. He groaned again, feeling her tongue flick the head of his cock. He could tell by her playful teasing that she was enjoying sucking him as much as he was enjoying being sucked by her mouth and teased by her amazing tongue. "Erika, oh fuck, you're amazing." He groaned and gently pulled on her hair.

He pulled down her head and shoved his cock further into her mouth, he felt the head hit the back of her throat and held her head in place. With his cock deep in her mouth he could heard the sounds of her choking on his hard cock and felt as if he'd cum any time soon. "No..." He thought to himself, this can't end yet. He released her and let her continue her blowjob on him. He wondered how much further he could get with her.

 

[xxerikamariexx]

She could feel him beginning to tense up. She knew he was going to release soon and she was excited for that. She knew she should feel guilty because this was her sister's boyfriend afterall but Jenny didn't know how to please or keep a man. And the way Erika saw it, she was doing Jenny a favor. Erika took Mark's dick from her mouth, spit on it before engulfing it in her pretty mouth again.

She knew Jenny would probably be home soon so she didn't know just how much time they were going to have left. But she was going to use all this time because if she was being honest, she was pretty lonely. Her boyfriend Matt had been an asshole lately and she surely wasn't getting laid. Matt expected to just lay back while Erika fucked him and that wasn't enjoyable for her...not in the least.
