My Stepbrother's Promise (Contemporary Stepbrother Romance)

by Anne Burroughs

  I did my best not to stare, but she had nothing but smooth skin showing, and my mind wondered whether she was trimmed close or completely shaved. As was happening nearly every time she visited, I had to pretend to re-arrange my pillows, dropping one in my lap to lean on, hoping that she couldn’t see the rock hard erection I was hiding.

  So as we rode to the lake house, we had spent the past year settling into a comfortable if slightly distant friendship, marked by my suffering from constant sexual tension and desire. I knew she didn’t share my feelings, as she was just so damn natural and friendly. She was so poised and calm that there was no way she was experiencing what I was, with the awkwardness and furtive glances.

  She was sitting next to me in the back seat, wearing a cotton sun dress, and I was so much taller than her that it was easy for me to look down the front where she had unbuttoned it enough to reveal a good deal of her gorgeous tits. To make matters worse, her nipples were hard and pushing against the thin fabric. Jeremy had once asked me if I had seen Jenny naked, and the truth was that I hadn’t, but I would have given practically anything for the opportunity. She wasn’t beautiful like a model, she was pretty like the girl next door, and she was curvy like the Hispanic woman from Modern Family. It was just my luck that my sister was my ideal woman.

  I adjusted my shorts as Mom looked over her shoulder and started a new variation on my least favorite conversation. “Aidan, I know I’ve been pressuring you to go out with some girls and date, but I’ve been thinking. You’ll meet a lot of girls at UCLA, and they’ll be smart and independent." She paused and then added, "You won’t have to worry about your Dad or I judging them.” She chuckled. “So it’s probably been a blessing that you didn’t fall into bad habits with high school girls, especially with your father there to let you know what exactly you’ve been doing wrong.”

  “Hey!” Dad replied.

  “I have no idea what you mean, Mom.” I glanced at Jenny, but she was staring out the window.

  “Oh, don’t be that way. You’ll have fun at college, and we won’t be there to make you second guess yourself.”

  “Again, Mom. No idea.” I was hoping she’d get the hint.

  “Just remember to buy lots of condoms!”

  “Hey!” Dad replied, which was about the extent of how far he would object to something Mom said.

  “Gross, Mom!” I looked over. It was Jenny. She made a strangling motion toward the back of Mom’s seat. I smiled.

  Mom ignored her. “I sometimes think the two of you are too close.” I felt my knees go weak as Mom said the words. I glanced at Jenny, but she just stared at the back of Mom’s head. Did Mom know? How could she know that we kissed, that I masturbated practically every night to Jenny in various positions and places? Did she know? “I love that you two are close, but it probably wasn’t healthy having you spend so much time together when you could have been dating your classmates.” I breathed out, not even realizing that I had held my breath. She was just editorializing.

  “Mom, please,” Jenny’s voice was a bit strained.

  “You have no room to talk, young lady. You are in the same situation. I’m just glad you’re already on the pill.”

  “What? Jenny’s on the pill?” I was so shocked I blurted the words out without even thinking. I looked over and Jenny was furiously shaking her head mouthing the word “please.”

  “How a woman controls her period is none of your business, son.” It was Dad, uncharacteristically interjecting himself in the conversation.

  “Jesus Christ, can we just change the subject?” Jenny’s frustration was apparent to everyone, so we all remained quiet.

  After a few minutes, Dad spoke up again. I don’t know what was going on, but he was more talkative on the drive to the lake house than he had been during the previous year. This did not bode well in my opinion. “I’m just glad you two are so close. Your Mom and I never thought that we would have both a daughter and a son, and when we found each other, and you two met, the joy you found in each other, well, it was special.” I couldn’t believe it. My Dad was getting choked up.

  “What your Dad is trying to say is that we were all brought together later in our lives, and yet everything has worked out so wonderfully. I don’t know a better brother and sister than you two, and this is what this whole weekend is about—celebrating our years together, and a brother and sister ready to face the world as adults."

  The rest of the drive was quiet as Mom and Dad held hands. I browsed Reddit on my phone, while Jenny, well she just stared out the window, probably already dreaming of being away from us and off in Rhode Island.

  Chapter Six

  * * *

  Jenny

  While Aidan was gorgeous and sexy year round, he was never sexier than during the weeks before and after the end of swimming season. Like all swimmers he shaved his head and all the hair off his body. It supposedly made them swim faster, and I guess every little bit counted. Whether it actually worked or not I didn’t know, but I loved it. With the sharp cheekbones and his narrow face, his bald head would make me warm just looking at it.

  I once asked Will Hansen, one of Aidan’s teammates, if the swimmers shaved all their hair, glancing down to make my point abundantly clear. He just laughed and said the Swimmer’s Code said that you could only discover that secret first hand. He raised his eyebrows in some sort of awkward invitation. I just walked away, my curiosity burning only brighter.

  I had talked to Aidan plenty of times about swimming, but ever since the debacle with the kiss I never had the confidence to ask him if he shaved his pubic hair or if I could feel his smooth chest. But I badly wanted to run my hands down his chest and let them reach into his swim trunks, where I was sure I would feel smooth skin. The image had fueled countless fantasies for me.

  Our birthdays were during the end of swimming season, so as we drove to the lake house I couldn’t help but glance at Aidan’s beautiful face and his bald head. At one point Aidan stretched, and his leg brushed against mine, and I felt electricity flow up my leg and through my whole body.

  I was so embarrassed. My parents were a couple feet from me, and my brother was sitting right next to me, and I was getting wet while my nipples were hard. I stared out the window, hoping to think of anything but Aidan’s smooth body.

  We got to the lake house at about eight o’clock, and the sun was already on the horizon. Aidan went into the house for some reason or another while I helped Mom and Dad unpack. I grumbled about Aidan, but Mom and Dad just shrugged. They weren’t going to let anything ruin this weekend.

  Aidan had even left his bag in the Range Rover, so I grabbed it to take to his room. The lake house had three bedrooms on the second floor and a communal shower and bathroom at the end of the hall.

  I reached the top of the stairs with Aidan’s bag when I stopped cold. At the end of the hall Aidan was in the bathroom, the fluorescent light filling the room and the end of the hall with a bright light. He was standing on his tip toes looking into a cabinet above the sink. The door of the cabinet swung out toward the hall, and with his head behind it he couldn’t see me.

  He was completely naked.

  As he looked in the cabinet, he turned a bit to the right, and I could see everything. I was frozen in place staring at Aidan’s astonishing body, and, more than anything, his long thick cock. If you’re a girl with a cell phone and Internet access, you pretty much don’t get to the end of high school without having seen dozens of cocks, from porn stars to desperate classmates who think an anonymous dick is their path to the inside of your pants.

  So while I had seen photos of just about every variation of cock possible, I had never seen one live, and I had never seen one quite as gorgeous as Aidan’s. It was curved down but seemed semi-firm, like it was just moments away from being ready to slide into me. And what drove me even crazier was that he was completely shaved. I couldn’t help it and slid my hand between my legs, the thin sun dress providing little resistance.

  �
�Mom! Where are my swim trunks? I want to get a swim in before it’s jet black out, and I can’t find them in the cabinet!” Aidan’s voice rang out through the house, and I quickly took a few steps backward, dragging myself from the view even as Aidan turned to the left, and I could see his equally gorgeous ass. God, I loved that he was a swimmer.

  I yelled up, “I’m bringing up your bag. I’m sure you have a pair in here.”

  I had to smile when he replied, “Shit, hold on. I’m naked. Let me grab a towel.” A minute later he called out, “Decent!”

  I walked up, and as my eyes crested the top step I could see Aidan with a white towel wrapped around his hips. “Why didn’t you just grab your bag?” I asked as I approached.

  “I didn’t have time. I knew Mom stored some trunks up here, and I wanted to hit the lake before sundown.” He looked over his shoulder. “I guess she moved them.”

  As he looked over his shoulder I glanced down. His cock was pushing forward against the towel. My mind started to torture me. Was he excited about my presence or was he really just that big? I handed him his bag. “If you really want to freak out Mom and Dad, you should just skip the suit.”

  As soon as I said the words I wanted to kick myself. God, could I have been more stupid? He would see right through me and know that I wanted to see him naked.

  “Ha,” he chuckled. “That would seriously freak Mom out!” He turned toward the door to his room, and then looked over his shoulder at me. “Thanks!”

  I was glad I wasn’t staring at his ass.

  Aidan

  I did my best to be casual, but Jenny was standing at the top of the steps, and the sun was setting and reflecting off the lake and through the huge glass windows that covered the front of the house. The result was that she was backlit, and I could see every curve of her body through the thin dress. I was getting hard while watching her, and since I was only wearing a towel I did my best to move things along. I turned to walk, only pausing to look back to tell her thank you.

  She had turned, as well, and I could see her profile perfectly through the backlit sun dress. Her tits were gorgeous, large and yet firm. She didn’t have a model’s body—she had a porn star’s body, and the thought made me even harder as I considered that thought.

  No one knew Jenny better than me, and she was kind, generous, smart, strong, and all of those things you would applaud in a strong young woman, but what if she was hiding a porn star underneath all that? The thoughts consumed me as I retreated to my room. I locked the door and gave up any idea of swimming. Instead I lay on my bed and thought of Jenny with the porn star body.

  Would my sister deep throat or do anal or just yell out “fuck me!” as I held her hips and or pulled her hand while I thrust into her from behind? She was too hot for me to finish after thinking of just one scenario. I wanted to savor her, and I walked through a few fantasies before I came. Each one starting with her profile in a sun dress, the sun shining through, and my hands a mere caress away.

  The lake house had a lot of room for everything except, oddly enough, dining. So Mom, Dad, Jenny, and I were crowded around a small square table for a very late dinner. I sat across from Jenny, while Mom and Dad sat across from each other. Thank God Jenny had changed into a cotton shirt and jeans or I would have stabbed myself with a fork while staring at her.

  Everyone tended to fold their legs under their chairs due to the room, but I was too tall, so I had to stretch my legs out, which put them under Jenny’s chair. After the third time she kicked me, she replied, “Oh, so sorry, Aidan!” I then felt her slide her feet under my legs and then cross her legs at the ankle. Her legs were basically holding mine in an embrace.

  “Is that better?” she asked, smiling.

  Oh God. How the fuck was I going to be able to spend three days with her if her just squeezing my legs with her ankles was turning out to be one of the most erotic things I had ever experienced? The worst part was that I was getting hard and couldn’t adjust myself due to my legs being held by hers.

  We did a lot of reminiscing, and most of the conversation focused on how lucky we all were that Mom and Dad had found themselves after awful marriages, but the whole thing was uncomfortable for me. At one point Mom looked at me and said, “And I’m just so thankful that you were able to have such a wonderful sister.”

  I looked at Jenny. She smiled the sweetest smile and then squeezed her legs against mine. I knew she had no interest in me and that she meant it only as a friendly gesture, but it drove me crazy. I thought about her legs wrapped around my waist and squeezing me in the same way, and as if that wasn’t bad enough it led me to thinking about her pussy wrapped around my dick and then squeezing me.

  “Aidan?” My mom interrupted my thoughts, and I noticed her looking at me quizzically.

  “I’m not sure I can put into words how much Jenny means to me, Mom. I am so grateful that you and Dad found each other.” From the smiles around the table I knew that I must have nailed it. Jenny was staring at me, and I could see the love in her eyes, and I tried to convince myself that it was more than just sisterly or friendly love.

  Maybe she felt the same way. I knew it wasn’t true, of course, but I clung to hope, unreasonable as it may have been. Hell, the whole day was one comment about us being brother and sister after another. If there was one thing that I assumed would freak Jenny out about us being a couple it would be Mom and Dad seeing us as brother and sister. And if I were honest with myself it bothered me a lot, too. What would Mom and Dad say if they learned we were having sex?

  She squeezed my legs again and said, “No offense to you two, Mom and Dad, but Aidan is the best thing that’s ever happened to me.” She was staring at me as she said it. Her hazel eyes, complex and beautiful just like she was, were entirely focused on me.

  It was at that point that I decided to ask her about the promise she made five years earlier. It was such a childlike thing—a promise to French kiss when we turned eighteen if we never had before then—but I was desperate. I guess I hoped that the kiss would lead to more, as unlikely as that sounded. I didn’t want to be the one to bring up the promise as she was the one who made it, but I wasn’t even sure if she remembered it, and my hope was that I could introduce it as a fun and innocent rite-of-passage that would close the chapter of our childhood.

  Before I fell asleep I walked through all the scenarios where I could bring it up without making her suspicious of my intentions. The trouble was that I was rather analytical, and even if we let passion take us I couldn’t just limit my thinking to us fucking by the lake. I thought of making love to her, holding her, and dreaming of a future together.

  But soon she would be leaving for RISD while I would be at UCLA. It was a chapter in our lives that filled me with fear. Even if we made love on the grass shore of the lake, what then? And our parents? They would disown us for sure.

  I tried not to think about the vague potential of a future together. Such a dream worked when we were thirteen. I grasped a stupid little promise that seemed more innocent and sad as each year passed by, but it sustained me. But even if we were to make love next to the lake, what could possibly sustain that? We would be two thousand miles away for four years.

  In the end, I rejected my fear and sadness over our separation and focused on hope. Wonderful innocent hope, borne of a small promise that Jenny made to me when we didn’t have to think of a future.

  Chapter Eight

  Jenny

  Aidan slid his legs between mine, and I just about fainted. After I had seen him naked I retreated to my room and pretty much exhausted myself bringing myself to orgasm, spending the whole time just imagining his hard cock taking me in every conceivable way. So when Mom called us down for a late dinner, I was still wired. I thought masturbating would relax me, but it just made me want him for real.

  I moved my legs out of the way, but after the third time his legs stroked mine as he stretched
I wondered if he was doing it on purpose. The thought that he was being so provocative as to send a sexual message while sitting right next to our parents made me wet and my nipples hard. Thank God I had changed into a bra and thick blouse.

  Finally, I couldn’t take it any more. I wrapped my legs around Aidan’s, with them resting on my crossed ankles. I couldn’t think of a more blatant message that I wanted to wrap my legs around him, but as I looked at him, he barely showed any acknowledgement. It was as if he was just glad that I was no longer kicking him.

  As dinner went on I didn’t give up. I told him I loved him and squeezed his legs, but there was no response from him. In fact, more than anything, he looked uncomfortable. At that point, I was desperate, so I decided that the next time we were alone I would bring up the promise I made to him when we were thirteen. I doubt he even remembered it. The last time it was mentioned was during our blow up over Katie and Jeremy, and that was just a passing mention.

  But it was something. I would mention the promise, say something funny about keeping them, Aidan would laugh, and then we would kiss. I didn’t know what I would do at that point, but I was strongly considering just shoving my hand down his pants. The worst case scenario was that I would get a chance to touch his gorgeous cock.

  Dinner was nothing but restrained sexual tension. I excused myself as soon as I could and fled to my room. As I lay in my bed, I kept thinking of the moment I would bring up the promise. We would be in his room with the door closed, and then we’d be naked on his bed. Sure, Mom and Dad would be wandering around somewhere, but that added to the thrill. We’d just have to be quiet.
