My sister Jen and I had a fun and relaxing summer after our so-called 'honeymoon' in Cancun, successfully continuing our illicit love affair under the roof of our parents' house, despite almost getting caught fucking in Jen's bed by our mother. It was risky, but as lovers, we were becoming intimately familiar with each other in ways we had never been able to do as just brother and sister.
My sister is the girl next door type that any guy would easily develop a crush on at first sight. She is kind, smart and funny, but a bit shy until you get to know her. Her cutely bashful smile might be her best feature out of many. Or is it her soft, pliable lips? Or perhaps her dreamy, baby blue eyes? Maybe it's the light summer sprinkle of freckles on her face that accentuates her fair complexion? Or is it her slightly upturned nose that enhances her feminine features? Maybe it's her long blonde hair that cascades down her supple neck and over her graceful shoulders? It's too hard to choose just one thing to like about my sister.
Jen also has a great body to match and prefers to wear clothes that tend to show off her slender feminine figure. Usually she preferred shear blouses and jean shorts, which exposed her taught tummy, supple ass, and sinewy legs. Sometimes, Jen wore nothing more around the house than a bra and panties.
One time, mom chastised Jen for wearing her underwear around the house and begged her to change into something more modest.
"Jenny, you shouldn't dress like that, especially around your brother. Go put something else on." Mom would say.
Jen rolled her eyes up at mom and turned to tease me and asked, "What do you think Jason? Do my bra and panties make you horny? Should I go and change? Am I getting you all hot and bothered, little brother?"
"Whatever, Jen! I hadn't really noticed. It's no big deal, mom. I'm not even paying attention. She's my sister. I don't think about her like that. I don't really care what she wears. I just want to finish watching the baseball game." I lied for mom's sake, while winking at Jen and making lewd suggestions to her with my tongue.
Jen smiled mischievously at me and ran up the stairs to change out of her bra and panties. She came sauntering back downstairs dressed instead in a tiny bikini that was far more revealing than her underwear. "This better?" Jen asked mom, twirling around like a ballerina, showing off her hot sexy little body in that barely-there bikini.
This caused our mother to throw up her hands in exasperated surrender. "I give up! You kids! I'm going to make lunch!"
"You mind if I watch the game with you Jason?" Jen asked as she answered the question herself by sidling up next to me on the sofa of our family room. She placed her dainty hand on my lap and whispered in my ear, "How's little Jason doing?"
"Jen, mom's right in the kitchen. She could walk in here any minute." I mumbled under my breath, unsure how far she was willing to take this.
Jen just looked me in the eyes with those big bright baby blues of hers and pouted, which deflected my already weakened resistance to her, as she unzipped my shorts. She pulled out my semi-erect cock, and began stroking it with her hand. I listened intently for any sounds of our mother in the kitchen. Thankfully, I could hear her talking on the phone and the banging of pots and pans. Jen got down on her knees in front of me and lovingly began kissing my cock, licking up and down the shaft, before putting it in her mouth.
"Jen, we could get caught. This isn't..." I trailed off, gasping instead, trying to catch my breath. Attempting again to get her attention, which right now was focused intently on sucking my cock, I cried out quietly so mom couldn't hear, "Jen...Jen...JEN!"
With that, I grabbed the back of her head with both my hands and shot what felt like load after endless load of cum in my sister's mouth, right there in our family room knowing that our mother was in the next room and could walk in at any time. Jen pulled away from me and opened her mouth wide to show me my ejaculate pooled in her mouth; strings of it coating her teeth. She closed her mouth, swallowed hard and smiled.
"Yummy! I don't think I'm going to need to eat lunch after that little snack. That filled up my belly." Jen giggled.
The risk and danger of getting caught by our parents was intoxicating and throughout the course of that summer, we must have had sex in just about every room in the house. We even managed to fuck on our parent's bed one night when they went out to dinner. The bed on which we were both conceived.
We both soon became experts on each other's bodies that summer. My fingers, lips and tongue had become accustomed to each and every curve and crevice of my sister's lithe naked form. My hands and fingers learned how to lovingly caress all parts of her body: her modest but distinctly feminine breasts with their pink, sensitive puffy nipples, sitting at perfect upright attention on her slender, 5 foot 9 inch frame; her youthfully flat tummy; the sharp bony curve of her hips; the small indentations of the curved dimples on her lower back; her lovely firm ass cheeks that I would playfully squeeze and bite; down to her pussy, lightly covered in downy soft blonde pubic hair.
By the end of our first summer together, my cock had been in her every orifice; even her tight little asshole.
One hot summer night, as we were engaged in a passionate 69, Jen's luscious ass rising over my head and her wet pussy sliding across my lips, I started teasing her butthole ever so gently with my fingertips. She had just showered and was fresh "down there." Her little brown eye, as I've heard it called, was literally winking at me, as if enticing and inviting me to kiss and lick it. I traced my tongue from her pussy up towards her taint and slid my tongue up and down and in a circular motion around her tight little butthole.
"Honey, what are you doing down there? That's the wrong hole." Jen giggled, drooling as my cock popped out of her mouth.
"I read that there are lots of nerve endings in the anus and I thought it would be something you might enjoy, babe." I responded, sounding a little too clinical, perhaps. "Do you like it?"
(Yes, we started calling each other by treacly pet names: Dear. Honey. Babe. Baby cake. Sweetie. Stud muffin. Lover boy.)
