On the way home Part I (Inc, Bro, Sis, Ped) “Can you just sit still without jumping if you are going to sit on my lap for few hours, Di” I yelled at my little sister Diana. Di just turned her head, stuck her tongue and made her face to aggravate me more, but I knew that I was stuck with her for several hours in the back of tow-truck. Our road trip to northern beaches of California ended with a disaster when my dad’s newly restored 1964 Studebaker broke down on highway 101 and having to tow it all the way to Sandy, Oregon. Luckily for us, uncle Bob runs an auto repair shop 50 miles from where the car broke down and he came and rescued us, by loading the Studebaker on his tow truck driving us with it home. The only problem was having two toddler cousins that we had to take along with us since uncle Bob has been a single parent ever since Aunt Rita passed away last year. With his kid’s car seats in the back of the tow truck, Di and I had very little room and therefore she opted to sit on my lap for the ride home, while my parents and Uncle Bob, who drove the truck, occupied the front seat. We kept crawling behind lumber hauling trucks on HWY 101 when the sun was getting ready to set. Both our cousins fell asleep around 9.00 pm and I tried to be as comfortable as I can be with my fourteen year old sister Di on my lap, who tried restlessly to get herself settled to take a nap herself. Di and I didn’t have much in common since four years separated us. We didn’t have common friends or played together or anything, than to sometimes watch the same programs on TV. But, I loved her as any brother loves his sister and protected her when necessary. Di is a woman waiting to be born our mother always said, and I think that is true since she was blessed with a very attractive face, but as with many teenagers her age, she was still trying to shake some of her baby fat off her body to be truly stunning. In my case, I always liked girls with large buttocks and rounded legs, so I always thought Di was pretty, except for her still developing breasts. As the darkness started to get thicker, we navigated through the mountainous roads heading home. Mom dozed off on dads shoulder and Di leaned against my body and tried to doze off herself as Uncle Bob took a sharp turn making Di loose her balance. She quickly tucked her shines under my legs to stay in balance. “Are you cold?” Di asked while grabbing a beach towel from the bag on the floor and covering her exposed legs. “Not really?” I answered as I was being heated by her buttocks resting on my lap. Di reached behind and grabbed my left arm and brought it around her front, just below her breasts and rested her head again on my shoulder. I rested my right hand on her thigh, over the towel. The ride on a tow truck wasn’t comfortable as I started feeling every imperfection of the road as we rode. To make things worse, every bump we hit made the truck move several times as the weight of the Studebaker that was in the back kept moving longer. To add to this difficulty, I started feeling back of Di’s bare thighs on my thighs as the dress she wore had ridden upwards due to the movement and caused unintended sensation on my cock. Not being with my girlfriend for nearly ten days may have had a factor as well. I tried to close my eyes and focus on other things to forget the feelings between my legs, but I found it difficult when Di slid down a bit causing my right hand slid near right breast. I looked out the window, seeing nothing but the darkness. I tried to think about other things again. But my cock kept on adding length involuntarily and I didn’t want Di to feel it or wakeup and find that I was having a hard-on. This was the first time ever that I wished I had a smaller member, but I am and I have been proud of my thick eight inch tool. “How can a guy not get a hard-on when a girl with silky bottom is sitting on his lap and her pussy is exhaling moist warm air at his cock?” I tried to reason with myself. Then I though the best remedy might just be to relieve the tension building up in my sack knowing once it is relieved of boiling load, my dick would settle down for the duration of the ride. But I wanted to make sure that I didn’t do anything drastic or to wake my sister, Di up. I slowly slid my hand under the towel in search of my cock, but found it difficult to reach between Di’s thighs. I decided to leave my hand on her thigh till an opportunity came to reach further to grab my cock. Di appeared to be faster sleep on my shoulder, since she did not move. I felt the softness of her thigh where my hand rested and proceeded to slowly reach down again to my pulsing member, but again I was afraid of forcing my hand between her thighs, since she could wake-up and make me feel as a fool. However, I was encouraged by her none action to having my hand on her thigh, that went on to slowly caress it towards her inner parts. Then without thinking twice, I brought my left hand around her body and placed it over her other thigh and let them wonder up and down ever so slowly caressing them and moving in between them to break loose my cock. I felt the heat came from between her thighs. At that moment, I wanted so desperately to run my hands down her smooth, legs, to feel the heat that generated between her flawless thighs, but I refrained. My cock was hard as it has never been. Even though I wasn’t doing much, just the thoughts of fondling my sister’s naked thighs somehow got me excited and I kept caressing her inner thighs while massaging my cock between them with the other hand. I knew she was faster sleep by the way she was breathing close to my ear, so I continued with my daring action while our parents were only few feet in front of us. Not wanting to wait to any longer to release my load, I tacked my stomach muscles in and pulled down the elastic band of my shorts, slid my hand in and slowly brought my thick cock out to breath warm air between her thighs. My cock angled to left, resting on Di soft inner thigh. I waited for a second before placing my hand on the head and slowly massaging it. Then I found it more pleasurable to rub my cock on her thigh to dry-fuck than to massage the cock-head to shoot in a desperate attempt. As I continued to rub my cock on her smooth skin, pre-cum that oozed off it slippery and much more pleasurable sensation. What happened next almost scared the hell out of me. When Uncle Bob took another sharp turn, Di brought her knees together and leaned on me neck to balance her, sandwiching my hard cock between her inner thighs. I thought that I got caught with hands in the cookie jar and even wondered if parents were looking in our direction, but the luck would have it, Di went right back to sleep, but didn’t part her knees. Not wanting to cause further panic, I rested, but soon found that having my cock between her smooth thighs to be a wonderful experience as the tow truck continued to vibrate, Di’s hips moved rhythmically making my cock ride in between. By then, her thigh were covered with my pre-cum made it so pleasurable and I simply placed my hand over the cock-head and massaged it gently. I thought it felt good before, but I could hardly believe how great it felt now. I suddenly felt Di’s hips jerked forward my erection. Then instantly I felt her thighs tightening around my cock as we rocked with every jerking movement of the tow truck. The heat I felt racing through my cock seemed to double as she firmly held it between her soft thighs, now very slippery and wet with my pre-cum oozing between them. I placed my hands on her knees and slowly started to thrust my cock between her soft and creamy flesh. I felt the pleasure climb higher and higher with every passing moment, bringing me close and closer to climax. I became bold and wrapped my arms around her body, I stroked my hands along her belly, moving up until I had both of her small tits over the dress, cupped them n my palms. I knew she was still faster sleep by her breathing pattern. Feeling her small nipples sent a fabulous sensation down between my legs, causing juice to boiling in my balls, knowing that I was playing with my sisters sacred belongings. I rubbed and squeezed them softly. I felt my balls begin to tighten and I knew I was going to blow my load. I quickly covered the head of my cock to assure no cum would fly above it. The bursts of hot sticky semen blasted into my hand and slowly dripped down to Di’s thighs. I waited for few seconds to regain my composure then I quickly cleaned the seaman off Di’s thighs with the towel and pulled my pants up. “We will make a gas stop in few minutes” Uncle Bob announce and I closed my eye and acted as I was faster sleep.
