"I'm all set, Ben", a tall woman with shoulder length blond hair stood near the door as she anxiously looked at the clock. The sounds of the room seemed unnaturally quite and she wondered if she was making a mistake leaving her only son by himself for a week. A thump from upstairs made her sigh and shake her head before looking at the clock again. She was about to miss her cab to the airport if she waited any longer. "Ben? I need to leave now. Get down here and give your mother a goodbye hug", she called. A shaggy 16 year old hair boy came out of the bedroom and was hurrying down the stairs, his features in a frantic expression. "Sorry, Mom, I was busy checking something online and forgot you were leaving" he said as if out of breath. Mrs. Tennyson sighed and felt she was making a mistake leaving her only son alone but she didn't really have a choice. Her sister was in the hospital and needed to be taken care of once she was released." Now remember there's a week's worth of food in the fridge and don't go out for take out, it's unhealthy for you", she said as Ben gave her a hug and saw a cab pull up. Ben nodded, "Bye Mom, call me when you get there and don't worry, I'll be fine!" he said as she entered and gave one final wave out of the cab's window as it pulled away moments later.

Ben Tennyson sighed as he was alone for the entire week for the first time in his life. He wondered if he should throw a party and invite everyone he knew as a way to celebrate being completely parent free but quickly decided against it. His mother would have a cow and would find out no matter how hard he tried to clean up. She had caught him before and his punishment was house arrest for 3 months. "Not something I want to do that again", he muttered before walking up the cobble steps and closing the door. The two unnatural sounds of his breathing and complete silence of an empty house was unsettling. Usually, he was used to having the TV on or playing video games upstairs in his room while his mother had book club meetings downstairs or invited neighbors for afternoon tea. But this time, he felt alone in his own house and a small thought was forming in the back of his mind that wished his mother didn't have to leave him right than and there. "I guess I'll start doing my homework", he joked as he slowly walked up the stairs to the second floor and opened the door to his room. Ben sat at the desk and sighed wondering if anyone was going to call him so he could delay his work but no one had called or texted him since his mom left. "Great, perfect way to start the weekend", he thought gloomily and pulled up a history book while beginning to flip lazily through the pages until finally picking a chapter and began to read.

An hour passed and Ben hadn't made much progress with his work. Drool was coming out of his mouth but he didn't bother cleaning it off. He just wanted to lay there and let darkness take him into a wondrous journey of sleep. His eyes began to close completely and felt like his wish was finally about to come true when a sudden ring brought him to his sense. "What the?" Ben stammered as his head shot up with a jerk and looked around until he found the source of the noise. The phone was ringing downstairs and he sighed as he got up from his unnatural sitting position and began to walk out of the room towards the downstairs kitchen. It took him a few seconds to bring the receiver to his mouth and hear his own voice when he croaked out a weak, "Hello". There was silence over the other line and Ben stood there thinking that it must have been a prank or wrong number before a voice broke his thoughts. "Hello back to you too, dweeb", and Ben groaned at who was on the other line. It was his 16 year old female cousin, Gwen, and Ben couldn't understand why she was calling him right now because they rarely called at home. "Hey Gwen, how are you?" he mustered as he looked at the clock and saw it was 5:50pm. "I just wanted to see what you were up too, since I know your mom left you all alone for the entire week.", she said with a slight sense of smugness that he detected. Cousins, whoever had to have them in their lives were truly a test of patience and tolerance, he thought while rolling his eyes. But Ben had to admit that Gwen had changed completely when they went on summer vacations each year and somehow grew closer because of their experiences shared together. Call it close living quarters because Grandpa Max had literally focused them to bond at whatever events they went to or saw across 50 states despite their protests when they were younger. Ben pulled a loose piece of hair from his head and looked at it before replying, "Yeah, I'm completely alone right now. And bored", he added hoping that she would take the hint. There was a small silence on the other end before Gwen said softly, "Do you want me to come over there, Ben. You know, to keep you company?" His face turned slightly red unexpectedly as he pictured Gwen showing up at his door in her typical outfit with her shoulder length red hair and dark green eyes that he always thought was somewhat attractive secretly. "Sure, that would be great. You could help me with my homework", he joked and he could hear her giggle as well on the other end as well. "I'll be there soon, see you, Ben", she said and disconnected.

Ben hung up the kitchen phone and leaned against the kitchen wall while in deep in thought. Gwen was coming over and he was happy she was. He didn't always want to admit it but she was the one person that could cheer him up right now even if they were family related. Thoughts began to race in his head about the amount of times she spent listening to his problems, cheering him up when he was depressed or sad, and even hanging out with him even when he wanted to be left alone. Gwen's overall personality and hobbies were also very different compared to other girls Ben knew at his age. She was an academic achiever that loved getting straight As while also taking martial arts courses after school and learning how to ride horses, something she often asked Ben to join in so they could bond more, which, he agreed several times recently even though he had trouble staying on a horse. He smiled while beginning to pull stuff out of the fridge to make a snack. "Lettuce, tomatoes, some bad looking tuna fish surprise, he looked as he poked around inside, "Ugh! This stuff is rancid", he gagged while sniffing a container that appeared to be leftovers from a few days ago. Ben took the container and dumped the leftovers into the garbage. He pulled out a few slices of bread and began compiling a worthy sandwich that even Grandpa Max would have been proud to eat before the doorbell rang. Ben placed his creation down after taking a few bites and moved towards the door wondering who it was before opening it slowly.

There stood a girl with long red hair and dark green eyes looking at Ben with an amused smile on her face. "Hey Ben, I'm here. Did you miss me?" she asked as Gwen Tennyson entered the house and looked around. Ben stepped back and saw that she was wearing a dark blue mini skirt with a black shirt on top with converse sneakers with a backpack slug over one shoulder and his heart skipped a beat. "No", he joked before she could playfully hit him. Ben led her to the kitchen, "I hope I didn't ruin any of your afternoon plans", he added while longing to see what her reaction would be. She shook her head and moved towards the table to clean up the mess Ben made, "I really didn't have anything else to do so I wanted to come", she added before locking eyes on him; she didn't realize how attentive he appeared whenever she spoke. The two sat down and Ben took a few bites of his sandwich with the only sound being his constant chewing and loud gulps. Gwen looked at him and shuddered at what he was putting inside his body and couldn't take it any more as food bits were now spewing onto the table as he chewed without notice. She sighed and stood up, "Ben, you are perhaps the only one I know that doesn't know how to chew properly with your mouth close", to which Ben stuck his mouth open to show his chewed contents. Rolling her eyes, Gwen grabbed his sandwich and tossed it into the garbage. "Hey, I was eating that!" Ben cried as she shook her head again and moved to the fridge with the intent of creating a healthier meal for the both of them.

"Did you hear about the upcoming History test for Galaski's this upcoming Friday?" Ben asked as he was chewing more carefully and well mannered due to being partially impressed of how much better Gwen's meal tasted compared to his own. She nodded while taking a bite out of her own meal, and locking her eyes on him, "It's supposed to be the hardest one for the semester. 33 Percent of the grade", she added as she watched him swallow again. There was a momentary silence before Ben replied, "I don't think I can pass his class right now. I've been struggling with the chapters and even been going to after school tutoring sessions but I don't think it's been effective" he moaned intentionally. Gwen got up and placed her hand on his shoulder for comfort as Ben buried his head in-between his hands while continuing to groan in exasperation and worriment. "If you want, I'll tutor you, Ben", Gwen said softly and he looked up at her while studying her face. It was a mixture of concern and anxiety; something the later he had never seen from hr before. "You would really help me out, even if it took hours of your time and patience? You know I'm not the best student in the world", he added sadly to which she wrapped her hands around him in an embrace to comfort him. She gently pulled his hands away from his face and saw a few tears forming in his eyes that led her determined with her answer, "I'll do it, I won't let you fail", Gwen said. Ben smiled at this while trying to wipe around his ears feverishly and replied, "Thanks, Gwen, I don't know how to thank you". She smiled and together, they walked up to the steps towards Ben's room and Gwen looked around. "Come on, let's get to work", Gwen said as she patted herself onto his bed and encouraged Ben to sit next to her, textbook in hand. He hesitantly sat next to her and together, they began to read through the chapter for Galaski's history exam.

"He's really trying", Gwen thought as several hours passed and Ben was getting more comfortable with reading with her and answering her questions during reviews. Gwen sat with one knee over the other while feeling Ben's weight pressed against her as her hair brushed over his face as he leaned over to turn the next page. Her eyes grew tired and her voice sounded hoarse from correcting Ben a few times with minor corrections. "You're really smart, you know that? I don't know how you could even remember so much at our age", Ben complimented and Gwen smiled at him while her brain subconsciously told her it was worth all the time and effort tutoring him. He looked up at her and never realized how pretty she appeared, in her mini skirt, leggings, dark blue shirt, and her overall complexion. Gwen had reached the age of growing up into a young woman and she didn't think of it until recently. All of her friends were usually gossiping about how big their breasts were getting along with their other bodily features after gym classes and yet Gwen was one of those girls that didn't really pay attention. Her definition of maturing into a young woman was defined of nature taking its course. But this was entirely different at this moment and Gwen suddenly felt funny as her cousin was eyeing her. "Okay, what year did the American Revolution end, Ben", she asked and saw he was chewing his finger nails. Grabbing his hand away from his mouth and clamping down on it with her own hand, Ben shock his head and asked, "Uh, 1787?", He waited to see if he was correct or to see Gwen correct him again. "Correct, I think you're getting better at this, Ben, I really do", Gwen said as she flipped the page and gave his hand a squeeze for encouragement.

Ben's face suddenly broke into a smile than Gwen couldn't resist smiling back. "Gwen, I…I wanted to thank you for helping me out with this. You didn't have to but you did…" he said sincerely and locked eyes with her. She started at him, "No problem, Ben, you know you could always count on me. I'll always be there to help you out when you need it, doofus", she added teasingly. Ben suddenly grabbed her by her arms and began tickling her. Gwen's girlish laugh soon followed as she was laughing, "Ben! Stop! That's not funny, we promised never to resort to tickling each other since when we were 10", she gasped as tears began to form in her eyes from laughing so hard. Ben increased his ticking in response and soon both cousins were laughing and rolling on the bed with the textbook and notes dropping to the ground but neither one caring. Gwen was on her back and saw Ben hovering over her with the same boyish adorable look on his face and messy hair that he never bothered to comb. Very slowly Ben leaned forward and gently placed his lips on hers. Her eyes shot up in surprise for a split second but then lowered as she relaxed and felt him move his body over hers. Without knowing what she was doing, Gwen opened her lips up and allowed Ben's tongue to enter her mouth as the kiss continued. "What am I doing?" he thought as he tasted his cousin's lips and found them to be sweet from the lip gloss she always wore. She made sucking noises as she playfully rolled her tongue over his and opened her eyes. "He tasted so good", Gwen thought as she could taste his saliva even though she knew he didn't brush after eating. She saw that Ben was enjoying this and wrapped her hands over his head and shoulder in a tighten grasp.

After a few minutes of locked kissing, Ben pulled away and looked at Gwen with a look of confusion and slight overzealous enjoyment. "Did. Did that really happen?', he asked her softly and realized that he had his hands over her waist. He was breathing hard and saw that she was as well, her small chest heaving up and down from excitement. Gwen nodded with a smile on her face as she leaned over to his face and pressed her lips against his again in another quick kiss. "It did. I don't know. I always liked you Ben, even though it sounds weird. But I do", she added hopefully. Ben sighed and for a split second, she thought he was going to leave the room and never speak to her again. He spoke in a small voice, "I always had the same hidden feelings for you as well. I don't know. Maybe it's because of the amount of time we spent together during the summers", he added as Ben scratched his head and looked around. "Maybe it was how I realized how wonderful you are as a girl even if you're my cousin", he added as he held her hand and brought her into a sitting position. Gwen nodded and said, "I felt the same way. I couldn't get through my life without even speaking to you. I need you", she added. He smiled and gave her a small kiss on her nose, "I will always need you too, Gwen, always", and she smiled back. The two looked at each other, Gwen's clothes and hair were a mess and Ben's hair was shaggier than before but they didn't care. Two cousins had admitted that they had feelings for each other and they knew that reactions from their friends and family would not come easy but they would endure.
