I've always known that my sister loved me. I probably shouldn't have been surprised to find out that she was actually in love with me. After all, I myself had feelings for her that most brothers usually don't have for their little sisters. Truth is, I should be grateful that Lillian finally forced me to face those emotions.
Ever since we were kids, Lily and I were always close. I like her, I always did. I never pushed her away to do my own thing, I tried to include her instead. I loved that she was always asking me about stuff, wishing to learn from me and looking so enraptured when I talked to her.
Lily was always very affectionate, hugging me warmly and holding my hand all the time, smiling that kind and open smile of hers, brightening my day with her sunny disposition. She always looked up to me, which made me feel important. Being around her felt good, right even, in a strange big-brotherly kind of way. The best way to describe it is to say that I felt like I belonged by her side.
I don't know many big brothers who, given a chance, would actually choose to spend time with their little sisters. Personally, I always enjoyed being around Lily, a lot. Not all siblings are affectionate or supportive as a given, but that was never the case with me and Lily. Ever since we were little, we got along so well and so effortlessly that, for the longest time, I was baffled whenever I heard that other kids would fight with their brothers and sisters or feel competitive or be mad at them.
Growing up we didn't grow apart. In fact, we got even closer. I'm just thirteen months older than Lily, so we were always in the same school, even though I was one year ahead. It was a good thing I was there for her. Beside being kind of shy around people, until puberty my baby sis was quite chubby, so the kids at school would often pick on her, the nasty little bastards.
Lily was so kind and sweet, so innocent, it really shocked her to the core to be made fun of for no reason. She suffered terribly when the other kids were mean to her, and I suffered alongside her. It was heartbreaking for me to see the sadness darkening my sweet Lily's face. I died inside at the sight of those huge tears trickling down her soft cheeks while, through desperate sobs, she asked me if she really was ugly and fat like the other kids said.
My pulse would race as I held my baby sis tight to me and wiped her tears away, stroking her long hair and soothing her, telling her that she was the prettiest and most awesome girl in the world, and anyone who said any different was an idiot. Lily clung to me with all she had, sighing less and less as I hugged her, until she calmed down. Only when she was smiling and breathing smoothly once again did I start feeling better too.
Any time Lily was in trouble, I tried to be there for her. Once I got suspended from school because I got into a scrape with some morons who were picking on her in the cafeteria. Our parents were glad that I stood up for my sister but they scolded me for getting in a fight, telling me that there were other ways to sort things out and blah blah blah. I knew all that, but when it came to my sweet Lily, I didn't care. The broken nose and black eye I got in that fight were treated like war wounds by my baby sis, who elevated me to the rank of living hero after that day. I also got a reputation for being a lunatic who would suicidally take on three bigger guys and kind of hold his own in a fight. People finally left Lily alone knowing that there was someone who meant business watching over her.
Some changes did occur when puberty hit, beside the obvious physical ones. There was a new, uncharacteristic tension between me and my sister whenever we hung out, which was most of the time. I wouldn't say it felt uncomfortable, but it did feel a bit weird.
By the time I started attending a local college, Lily was eighteen and on her last year in high school. At that point, it was simply impossible to ignore the electricity in the air whenever we were close. We were still very casual around each other, as affectionate as always, but now even the smallest contact between us had a new intensity to it.
Honestly, since puberty hit I had started seeing my sister in a new, entirely different light. Lily's baby fat was gone, replaced by soft womanly curves that I simply couldn't stop staring at. She was amazing, radiant and fresh and spellbinding in her simple, unassuming way of being beautiful. My heart beat faster whenever I looked at her, which was any moment I could.
Her tits were big and round, yet they showed just the minimum amount of sag, looking very firm despite their heavy fullness. Her tummy had flattened but it still looked so adorably soft that I often felt compelled to tickle her sides playfully just to have a chance to touch it, brushing her boobs in the process too. Her legs were shapely due to her daily routine of yoga exercises. Her ass was a vision of juicy roundness. I had to contain my groans every time I laid eyes on Lily's shorts-clad bubble-butt. My mind reeled and my groin was jolted into life when my sister walked in front of me, her meaty bouncy asscheeks swaying mouth-wateringly before my adoring eyes.
But even though her body looked different, my sweet Lily didn't change, nor did her caring, loving manners. If anything, my baby sis's shows of affection toward me increased in frequency and intensity. I couldn't help but feel tingly and flushed whenever she hugged me, pressing her buxom jugs into my chest and causing my pants to sprout a noticeable bulge, against which she unfailingly brushed her thighs and crotch. I winched at that and nervously laughed, trying to disengage from her embrace. Lily just purred, her arms holding me tighter to her.
At first I was embarrassed by my reactions to my sweet sister's gorgeous body, but she didn't seem to mind at all. Truth was, I often masturbated thinking about her at night, after we had cuddled in front of the TV or spent time together in my room, chatting and relaxing, usually lying side by side on my bed. By the time we said goodnight, I was unavoidably hard as a rock.
Of course it didn't help that Lily rarely wore a bra when she was at home. Her tits seemed to be always on the point of spilling out of her tank tops and her tight fitting V-neck shirts never failed to display a mouth-watering amount of cleavage. If that wasn't enough, the cotton shorts she wore around the house were flimsy and somehow undersized, so her spectacular ass was permanently straining against the fabric, her fleshy round buttcheeks enticingly outlined and partially exposed.
Horny as I was, beautiful and curvy and affectionate as Lily was, it was unavoidable that she should end up being my number one sexual fantasy.
I guess she was feeling the change too. There was a dreamy look in my sister's big warm hazel eyes as she tilted her head and gazed at me sometimes, when she thought I wasn't looking. She often bit her luscious lips or crossed and uncrossed her legs, pressing her thighs together as she talked to me from a deck chair while I did chores in the garden without a shirt on. It sort of comforted me to know that I wasn't alone in my weird attraction to my sibling.
I often watched porn on the internet at night, even though I always ended up picturing Lily in my head when I came. One night, right after I blew a massive load, my door burst open and my baby sis stepped into my room. My face burned red as Lily breezily came to sit on my bed right by my side, unperturbed by my nakedness.
