It had been several chaotic weeks in a row for Eric. He had just finished moving all of his belongings into the bedroom of his new home. After closing the door, he sat down on the bed and took a moment to gather his thoughts.

His mother had been very recently remarried. That event suddenly forced him to relocate in the middle of his senior year of high school. Their new home was in a different school district, so it would have taken a significant amount of time to commute to his previous school. Since he didn’t have his own dedicated vehicle, he was forced to switch schools mid-year.

Eric was happy that his mom had finally found somebody else. His father had already remarried, so there wasn’t really any hope that they would get back together. He just wished that she could have waited another couple of months. His mother interrupted his moment of reflection to call him to the dining room for their first “new” family dinner. After taking a deep breath, he headed to the table with the best smile that he could fake.

Eric’s new stepfather, Jim, welcomed him to the table. He seemed like a genuinely nice guy and was trying his best to make Eric feel at home. Although Eric had met Jim on several occasions, they were still getting to know one another.

Jim told Eric and his mother to go ahead and eat while the food was still hot. He said that his daughter, Kendra, would be home at any minute, but there was no need to wait. Eric wasn’t quite sure whether she still lived in the house full-time. There was still a girl’s bedroom just down the hall from him, but he wasn't certain about the living arrangements.

Just as everybody had filled their plate, the door from the garage swung open. A young woman charged into the kitchen in a flurry of expletives. Long, dark hair flew around in multiple directions as she flailed her arms and bantered. Apparently, her shift at the local coffee shop didn't go as she had wished. As she settled at the kitchen table, Jim apprehensively said, “Eric, this is my daughter…Kendra.”

Eric wasn’t sure how to respond to that introduction, but he gave a tentative “hey” in her direction. She didn’t seem to pay much attention to him or respond in any way. She did, however, ask him to pass the potatoes in her direction. As he grabbed the bowl and passed it to her, he finally looked Kendra in the eyes, nearly causing him to drop the bowl.

He had seen a few pictures of her previously, mostly as they were moving their belongings into the house, but they certainly had not done her justice. Eric stared at her for a few seconds, mesmerized by just how beautiful she was. She was a bit unconventional in style, wild, and understatedly pretty.

As Kendra aggressively tugged away at the bowl of mashed potatoes, Eric was awakened from his trance. From that moment forth, he felt like he needed to stare directly at his plate of food. Occasionally, he would look up, but only in the direction of his mother or Jim. He really wanted to look in Kendra’s direction, if only to affirm that she was as attractive as previously advertised, but he couldn’t work up the nerve to examine her further.

After dinner, Eric helped his mother and Jim clean up. Kendra headed straight to her bedroom, he assumed. She had disappeared, and her bedroom door was closed, so that seemed most likely. He was glad that she had left the room. She was making him feel quite uncomfortable, and he feared he was destined to feel that way anytime that she was around.

After he finished cleaning up, Eric took a seat on the living room couch. His mom and Jim were watching some sort of detective show that didn’t interest him in the least. He mostly just played on his phone and exchanged texts with some of his old friends. After roughly an hour, he decided to head to his bedroom. He politely said goodnight to his new parents and headed in that direction. As he neared the hallway, Kendra appeared from her room. Her hair was wet, which led Eric to believe that she had just showered, but that was not what truly caught Eric’s attention.

She was wearing a slightly oversized t-shirt. It didn’t seem to be an actual nightshirt, since it wasn’t really long enough to be worn as such. The material was either very thin or well-worn because it left little to the imagination. Eric could see virtually her entire upper body through the shirt, except for the area of her breasts that was covered by the "Bitchy but cute" decal. Kendra was very slender, and her breasts were small, but perky.

The bottom edge of her t-shirt rested at roughly hip level. That meant that there was a considerable area of her turquoise-colored panties exposed, even with her arms and shoulders at rest.

As Kendra passed Eric in the hallway, he crowded toward the right side of the hallway so they could pass each other. He thought to himself that any contact with Kendra would have been inappropriate, considering her distinct lack of clothing. The closer they got to each other, the tighter Eric hugged the wall. Kendra gave him a strange look as they crossed paths.

He heard her mumble, “Jesus, I don’t have a fucking STD or something!” as she headed into the kitchen.

Eric thought about apologizing, but decided to go into his room and close the door instead. He couldn’t imagine how he could possibly be able to talk to her without staring inappropriately. As soon as he closed the door, he wondered what Kendra had gone to get in the kitchen. He pictured her reaching for something on the top shelf and her shirt riding up to her navel, exposing her midsection. Perhaps the rear view of that would be nice, as well.

He briefly thought about opening the door and peeking in her direction, but he couldn’t work up the courage to do it. Eric wondered if she always dressed like that in the evening, or if he had just wasted his one good opportunity to get a bit of a show. Then he realized that he was fantasizing about his step-sister. He felt guilty about his desires and tried to think about other things.

For the remainder of the night, Eric remained in his bedroom. The only exception being one very necessary trip to the bathroom. There were three rooms off the hallway at that end of the house. The first was Eric’s bedroom, the bathroom was in the middle, and Kendra’s bedroom was at the end. As he headed to the bathroom, he saw that her bedroom door was closed and the light was still on. He was becoming very tormented about Kendra. As eager as he was to impress her, he was paralyzed by the fear of her inevitable rejection.

As Eric stood at the toilet, he realized that he would be sharing the bathroom with Kendra. He opened a few of the drawers and snooped around. They were filled with mostly cosmetics and hair care items, but he stopped dead in his tracks when he found her feminine hygiene products. Eric closed the drawer quickly and found himself embarrassed, despite the fact that nobody saw him. He stopped looking through the drawers immediately.

He quickly realized how familiar the two of them were about to be with one another's personal hygiene. Eric noticed the clothes hamper and cautiously lifted the lid. Near the top of the pile was a freshly-worn pair of pink panties. He stared at them for a second before closing the lid softly so that nobody could hear.

Once he returned to his bedroom, Eric couldn’t get Kendra out of his head. He kept picturing her wearing that t-shirt and turquoise panties. Sometimes he would think about those dirty, pink panties sitting in the hamper and wonder what they would feel or smell like. Other times, he would imagine Kendra taking a shower and picture her slick, soapy, delicate little body. He wondered what she was doing in her room. All of these crazy fantasies about a girl that he had just met a few hours ago were consuming his every thought. As he continued to spiral, it became apparent that his cock was not going to be denied for much longer.

Eric removed his shirt and yanked down his shorts. He hobbled over to the nightstand and grabbed a tissue with his left hand as he started stroking away with his right. It didn’t take very long until he was on the verge of orgasm. He tried frenetically to wrap the tissue over the head of his cock, but the cum flowed too heavily and with too much force. Several large droplets headed toward the floor but were intercepted by his shorts and underwear, which were still resting around his ankles.

He let out a sigh as he realized what a mess he had made. Eric finished wiping the cum from his cock and grabbed an additional tissue to pat everything dry, including his shorts. He tossed the tissues in the trash can and pulled his shorts up, though they were now featured with an uncomfortable wet spot.

That wet spot was a nagging reminder of what he had just done. Each time he thought about it, he was reminded of Kendra. It wasn't long before he pumped out a second round of cum. Once he had cleaned up the mess from his second release, Eric decided to go to sleep. He turned off the light and slid into the bed wearing only shorts and boxers.

Eric had to consciously refrain from touching himself for the remainder of the night. He couldn't stop thinking about Kendra, which led him to rub his erect cock against anything that he could. He finally fell asleep, but woke up a couple of hours later, face down on the bed and grinding his cock against the mattress as he slept. It was obvious that he had been doing it for a while because his cock was getting sore from the friction. Just seconds from orgasm, Eric flipped over onto his back, pulled his shorts down, and kicked the covers away.

Hoping that the previous two orgasms would limit the volume of cum this time, he simply went for it. His load was thin and watery, but there was still quite a bit of volume. Eric almost immediately felt the cum begin to trickle off his body. He reached for a tissue, but it was already dripping onto the bed sheets.

The following days were an exercise in sexual torment for Eric. Almost any time that he saw Kendra, he would get an immediate erection. He tried to avoid her as much as possible, but that didn’t work out very well. The nightwear that he saw Kendra wearing on their first night turned out to be pretty standard. That wasn’t helping his burgeoning infatuation/obsession with her, either.

Eric hadn’t had much experience with girls at that point. Even though he was already eighteen, shyness and lack of opportunities made him increasingly hesitant to initiate sexual contact. There had been a few girlfriends, but little more action than some over-the-clothes touching or an occasional drift underneath.

One evening, Eric had been doing homework in his bedroom. As he walked from his room to the bathroom, he caught a brief glimpse of Kendra as she disappeared into her room. She had just finished her shower and was walking to her bedroom wearing only a loosely draped towel. Since she was walking away from him, he only saw her backside, but it was basically in full view.

Eric hurried into the bathroom and closed the door behind himself. The air was still moist with the steam from Kendra’s shower. Out of necessity, he decided to try to pee, but one peek at Kendra's ass had already riled him up. He aimed his stiff cock down and toward the toilet in an uncomfortable fashion. After a prolonged wait, he managed to get the flow going, although it splashed all over. The cleanup was going to have to wait a while, though.

Eric immediately turned around and began to stroke his cock furiously. Even though his masturbation cycle was very frequent, he never seemed to feel satisfied. As his eyes drifted, he saw that the lid on the laundry bin was still open. He stepped over and looked down to find Kendra’s recently removed clothing.

He ceased stroking his cock and reached a trembling hand into the bin. Eric pulled a pair of cotton panties from the bin and quickly inspected them. They were black bikini panties with a silver Calvin Klein logo embroidered on the waistband.

Eric gave them a quick sniff and started stroking his cock with them. Before he could think about what he was doing, he had already ejaculated all over them. His head rocked backward, and he experienced the first brief moment of satisfaction that he had felt in days.

Feeling freshly content, Eric slowly gazed downward and realized he had left evidence of his obsession with Kendra all over the panties. He thought about disposing of them, but finally decided to tuck them inside the leg of Kendra’s jeans. Hopefully, they would not fall out on the way to the washing machine.

Eric cleaned up the bathroom as much as possible and returned to his room. He was still nervous about getting caught playing with Kendra’s undergarments, but that didn’t squelch his libido in the least. After catching a look at Kendra’s amazing little ass earlier, nothing was going to put out his fire for very long.

The following morning, Eric was taking a shower before school. As he stood under the shower, gently stroking his almost perpetually erect cock, he heard a noise. He pulled the curtain open slightly, only to let out a squawk when he saw Kendra sitting on the toilet just steps away. Although he didn’t see anything, he could hear the splashing sound of Kendra taking a morning pee.

“Uh, I…I’ll be out in just a minute if you need to use the bathroom, ” Eric shouted.

Kendra replied, “That’s okay. You aren’t bothering me at all. Continue doing whatever you were doing. I’ll be done before you.”

Eric didn’t answer back. He wondered what she had meant by that comment. Had she seen him jacking off in the shower? There wasn’t much visibility through that shower curtain, but someone could potentially see a shadow outline. Eric stood frozen with his back turned to the curtain for what felt like an eternity. He barely moved a muscle until he heard the door close again.

Once he finished his shower, Eric scampered over and pressed the lock on the door. He normally locked the bathroom door, so it was strange that he would have forgotten to do so.

He spent the entire day at school thinking about that interaction. One part of his brain said to make sure to lock the door every time from that point forward. The other side wanted Kendra to walk in on him, but, more accurately, it wanted him to walk in on her. He wondered if she locked the bathroom door. Something made him think she didn’t, particularly since she would have had the bathroom to herself for years. He was kind of surprised that she even shut the door, given her boldness.

The following several days were more of the same. Eric was beginning to question how much more sexual tension he could endure. Thoughts of Kendra were dominating his every waking moment. Although he knew that his obsession with her was unhealthy, he didn’t know how to make it more tolerable.

He had witnessed her walking from the shower to her bedroom several other times. One time, he got a particularly good look at her perky breasts. Eric made sure to leave the door unlocked when he took his morning shower in hopes of another intrusion. There was a similar one that occurred a few days later. Kendra burst in again and used the toilet, shouting at him not to freak out. He wondered if she was merely that casual about their living situation, or if she wanted to see him naked as much as he wanted to see her.

One night, Eric was doing his usual evening ritual of hanging out in his room and trying to eavesdrop while Kendra showered. As always, he hoped to get a peek at her as she walked back to her bedroom. Strangely enough, they still had barely spoken to one another.

Eric managed to work up the slightest bit of nerve on this occasion and went to see if she kept the door locked while she was in there. He didn’t intend to barge in just yet, but he wanted to verify if she kept it locked. Eager to find out if his imagined interruption was possible, he reached out and grabbed onto the doorknob, building the courage to slowly and quietly turn it.

Just then, the knob spun in his hand and was quickly pulled away. Only halfway paying attention, Kendra made no effort to cover her privates. Eric stood there wide-eyed as he finally got the full-frontal view he had been fantasizing about. Oblivious to his presence, Kendra continued drying her hair with a towel, but otherwise was completely nude. Unfortunately, after several seconds of aggressive toweling off, Kendra saw Eric standing in front of her. Kendra didn't react in any of the possible ways that he would have expected. She seemed to believe that he had just arrived and was waiting to use the bathroom, and made no effort to cover herself up with the towel.

“I’m done in here. It’s all yours, ” Kendra said casually.

Eric turned around and, instead of going to the bathroom, scampered back to his bedroom. He slammed the door and stripped completely nude within seconds. Without hesitation, he grabbed onto his already rock-hard cock and started to pump it aggressively. He barely got started when his bedroom door swung open. Kendra stepped inside, now with the towel wrapped around herself.

“Eric, are you alright? You didn’t seem like...”

Kendra paused briefly as she absorbed what was going on.

“Holy shit! That is a huge fucking cock!”

Eric tried to cover himself up with his hands, but he had already been seen. Kendra turned around, bolted into the hallway, and closed the door behind her. Eric nervously paced around the room, wondering if she realized that she had triggered his actions. Most of all, he really hoped she wouldn't tell their parents about the incident. A few minutes later, there was a knock at the door, and Eric wondered what the next embarrassment might be that he would have to endure. Fortunately, it was Kendra and not someone else.

“Hey, I’m sorry that I barged into your room. I didn’t realize that you were…You know...Doing that. I mean…I could tell that it was big, but I didn’t know that it was that big. Fuck! Your girlfriend is a lucky girl.”

Eric stammered, “Yeah...Uh, she loves it.”

Kendra challenged, “Okay, you don’t have to lie to me. I can tell by that answer that you don’t have a girlfriend.”

“Yeah, I don’t have one right now. I'm sort of in between relationships, ” Eric admitted, omitting the fact that it was pretty normal for him.

“That’s a shame, Eric. That thing should be getting lots of exercise, and not just the kind that you are always doing by yourself.”

Eric’s face immediately turned bright red. It was bad enough that he had been caught, but it was also evident she already knew how much he had been beating off.

“Don’t be embarrassed. It’s something that guys do all of the time…and girls, ” Kendra confessed. “Well, I can see that you are doing just fine, so I’ll leave you and your large friend to finish what you had started."

Eric was in a state of shock. The only thing that seemed to even resonate with her about that interaction was the size of his dick. He wasn’t sure why she thought it was big. Nobody else who had seen it had ever mentioned it.

He had been a bit of a late bloomer and was always quite undersized in that department. By the time he hit a late growth spurt, Eric had already finished participating in athletics and gym class. He had just assumed that the other guys kept growing, as well. Without other men the same age as himself to compare his size with, he had referenced internet porn as the standard. At eight inches long, he seemed average, at best. He did have a large pair of low-hangers, though, so maybe that made it look more impressive.

Just as Kendra stepped into the hallway, she seemed to have had a “lightbulb moment.” She turned around and charged back into the room.

“Wait a minute...Were you jerking off to me?”

Eric was mostly silent, other than some stuttering.

“You were, weren’t you?”

She started to chuckle.

“It all makes sense now. That’s why you always have a hard-on around me, and are always jacking off. You have a little crush on me, don’t you, Eric?”

Kendra walked over to the bed and sat down, still wrapped in her towel. She patted the bed and invited Eric, who was still trying to cover up with his hands, to sit beside her. He sat down on the bed, nearly an arm's length away from her. His face was still bright red, but he finally managed to be honest with Kendra.

“Yes, you are the most beautiful girl that I have ever known, and I can’t stop thinking about you.”

“Aww!” Kendra cooed. “You are so sweet.”

Kendra slid closer to Eric, leaned over, and gave him a peck on the cheek. He wasn’t sure what that meant, but he liked it. Eric’s cock was still fully erect, and he noticed that Kendra couldn’t stop looking at it.

She quipped, “Boy, that thing doesn’t go down without a fight, does it?”

The two chuckled for a moment. Eric added, “Very rarely.”

“I have never seen one that big in real life. Is it okay if I touch it?”

Kendra didn’t wait for a response; She just reached in his direction. Eric pulled away, involuntarily. Everything had happened too quickly, and as much as he wanted it to happen, he freaked out.

“Oh, okay. I’m sorry. I took it too far, didn’t I?” Kendra asked.

Eric blurted, “No, no. It’s fine. I just...don’t know if we are supposed to be doing this.”

“Why? We aren’t related. Besides, I’m pretty sure that our parents are fooling around in their bedroom right now. Why can’t we have some fun, too?”

“Ugh, gross, ” Eric groaned, “But, yeah, I guess it is fine. The step-sister thing just makes me feel like it's kind of dirty.”

Kendra sent an ultimatum, “So...Do you want to fool around, or do we each lock ourselves in our bedrooms and masturbate while thinking about each other? I know I’m not going to be able to stop thinking about that, " she declared as she pointed at my cock.

Eric leaned in and whispered, “Please stay.”

Kendra smiled back at Eric. Then, she ran over and locked the door. By the time she returned to the bed, her towel was already on the floor. Kendra slinked in between Eric’s legs and bent over. She grabbed hold of his cock and gave it several long strokes.

“God, you are a fucking beast!” Kendra groaned as she started to rub her clit with her free hand.

Eric reached in and clumsily caressed her breasts with both hands. Kendra slowly lowered to the floor. She started to lick the length of his cock and suck on the head, struggling to get much further without having to back away. Clearly frustrated with her oral technique, Kendra sprang up and climbed onto Eric’s lap.

She squeezed him tightly, pressing her firm breasts against his chest. Eric’s cock was pinned between them. Kendra started grinding her wet pussy against his cock, coating it with her sexual excitement.

"Can you feel how wet my pussy is? That's how much I want you inside me."

Kendra leaned back and pressed his cock against her midsection. In that position, it measured about two inches past her navel. She taunted Eric, asking him if he thought that he could fit all of his cock inside of her.

Her aggressiveness was exactly what Eric needed. Even though he was trembling with nervousness, he shook his head affirmatively and spontaneously kissed her on the lips. Undeterred, Kendra started to raise her body. As she grabbed hold of Eric’s cock, he held her hips and tried to steady her. As she was just about to lower herself onto his cock, she could clearly sense his nervousness.

Kendra lowered herself back down onto his lap and stared at him. Eric had already learned that he could not lie to Kendra. She saw through it every time.

“I’m a virgin, ” Eric blurted.

Kendra gave Eric a hug and a kiss. He feared that his humiliating confession would bring their encounter to an end. Instead, Kendra told him they were going to do whatever he wanted to. Eric, of course, said he was happy with the way that it was going, but Kendra insisted that it should be Eric’s fantasy. She failed to get much feedback until she framed the question a little bit differently.

“When you fantasize about fucking me, what position are we in?”

Eric thought about it for a second. Then he told her that she was usually on her back on the edge of the bed, and he was standing. He added that he wanted to see her beautiful face and watch her breasts jiggle as he thrusted. Kendra quickly agreed and said that it sounded like fun.

As the two gathered themselves and got to their new positions, Kendra asked Eric to take it slow at first. It seemed strange to him that an experienced girl would feel some hesitation about his size. As Eric approached Kendra, she let him know that she was on the pill. He thought he knew what she meant by that, but had to ask her more directly, just in case.

As Eric lined himself up, it was clear he wasn’t completely confident he was aiming it in the right spot. He pressed his cock softly against Kendra, and the tip of his penis guided gently to its intended target. One measured push later, he was about a third of the way inside her. She gasped and bit her lip.

“One more thrust like that, ” Kendra directed.

Eric complied, and the next thrust pushed him in about halfway. Kendra’s head rocked backward, so Eric gave her a minute to adjust. She was exhaling deeply, and her legs and toes were curled up at each of his sides. Kendra gave Eric a signal, and he started slowly rocking back and forth. She continued to lie flat on her back, staring at the ceiling until Eric said, “Kendra, look at me.”

She lifted her head from the bed and locked eyes with Eric. A smile appeared on her face as she called out, “Keep going. That feels so fucking good!”

As Eric increased the pace, Kendra let out a little sigh with every thrust. As great as it was, it was not the picture that Eric had drawn in his head. They weren't a loving couple having a romantic shared moment; they were two horny young adults having spontaneous, raw sex. Eric stopped and asked, "Do you mind if we change positions?"

Kendra seemed perplexed by his request, but she went along with it.

Displaying some actual aggressiveness, Eric grabbed Kendra by the waist and flipped her over onto her stomach. As he climbed onto the bed, she had already lifted her backside into the air slightly. Already an experienced veteran, Eric slid his cock back inside Kendra with a bit of confidence. Her body slumped onto the bed as Eric positioned himself on top of her. Her legs were spread wide, and her feet flailed around on each side of his body.

As he saw her already clutching at the bedsheets, Eric started to realize that the girth of his cock was actually his most impressive attribute. He decided to test his theory and plunged his cock in a little bit deeper. He heard Kendra whispering, "Fuck! Fuck! Fuck!"

"Do you like my big, fat cock, Kendra?" Eric asked. It was something that he never thought he would ever have the confidence to say.

"Fuck, yes!" Kendra groaned with her teeth clenched. "Keep going. I want you to stretch out my tight, little pussy!"

It was exactly the sort of positive reinforcement that Eric needed. His pace quickened, and he went at Kendra hard and fast. As he thrust away at her, Eric could feel her body quivering beneath him. It seemed like it was more of a reaction to being pushed to her sexual limits, as opposed to an orgasm, but he wasn't really sure. Still, he kept on at a vigorous pace until his lower body seized up and he emptied his load inside Kendra. The lights seemed to flash, and he felt like he was going to collapse on top of her.

Despite how satisfying it was, all Eric could feel was disappointment. It was quick, and he knew it. Plus, he was pretty certain that he hadn't been able to satisfy her the way that she had satisfied him.

Eric’s head and shoulders slumped for a moment. He withdrew his softening cock and took a seat at the edge of the bed. He was obviously upset with himself.

“I…I’m sorry. I know that wasn’t very good. It was too quick. I was too quick.”

Kendra was still trying to recover. She slowly got to a seated position, so she was facing Eric. Her eyes were pointed down as she sat with one leg hanging over the edge of the bed and the other extended across it. As he took a closer look, he could see that her formerly tight, little pussy was now agape and looking significantly disturbed.

"Fuck!" Kendra groaned. "Look at what you did to my pussy!"

He watched as Kendra slowly did a self-inspection in front of him. Her eyes never even glanced up as she took two fingers and easily slid them inside.

"I can hardly even feel that, " she added, as if in a trance.

Eric watched as her fingers probed in and out, going a bit deeper with each repetition. When she finally withdrew them, they were wet with a combination of her sexual excitement and Eric's cum. Kendra finally looked up, and a smile slowly appeared on her face. She swiftly extended her hand and smeared the fluid across Eric's chest.

He wasn't sure what sort of reaction Kendra was looking for, but Eric sprang into action and pounced on top of Kendra. As he pinned her to the bed, they exchanged a couple of brief kisses.

"Jesus Christ, Eric, how are you already hard, again?" Kendra questioned.

Eric simply smiled and offered a "Round Two." Kendra quickly declined, citing the fact that she was already going to be sore for a week. While he was disappointed by that answer, he was shocked to hear her immediately offer a "raincheck."

From that evening forward, Eric and Kendra's end of the house would never be the same. The following morning, Kendra interrupted Eric's morning shower, as usual. This time, though, after her morning pee, she joined him in the shower and "gave his hand the morning off." On her knees, she serviced him with both her hands and mouth. Although she still struggled to gain much depth, she was easily able to finish her task and swallow every drop.

Pressed for time, as Kendra's actions threatened to make him late for school, she would have to wait until that evening to get reciprocation. It was Eric's first time performing cunnilingus, but after a bit of guidance, he proved to be a quick study.

Their bedrooms, as well as the bathroom, would soon become a den of virtually non-stop fornication. Eric and Kendra quickly became quite comfortable with one another and didn't bother asking for permission. It became quite commonplace for either of them to be ambushed in the shower or even while they slept.

Their parents, who were distracted by their own newlywed status, never even had a clue.
