It happened on vacation

It happened on vacation.


While in the car on the way to the mountains for our family vacation my thoughts drifted to what I would be missing for the next week, namely my girlfriend or in other words doing without sex for the next 9 days. When your in your mid-teens (I am 16) you know how it is having to cope with the urges so you masterbate a lot and when you do finally have sex all you think about and look forward to is the next time and in between “getting it” you masterbate, hell you have to or you feel you will explode. Here is the problem: My parents rented a couple of small camping cabins, they stay in one and I will be sharing the other one with my 14 yr old sister…….so much for my “jack off” sessions.

We finally arrived, unpacked and stowed our things. The cabins are small but self-contained. The one I share with sis has two twin beds with a nightstand in between. Our parents tried to rent cabins side by side but we ended up about 3 cabins apart. It was a long drive and my sister and I ached to get into the pool. She ducked into the bathroom first to change and while I waited my turn all I could think about was getting some “relief”, if you know what I mean. Sis came out of the bathroom with a new bikini on that she bought before we left home. It was the kind that had the ties on each side.
I’m not sure if it was me being horny or she just looked good enough to eat but either way I couldn’t help but to give her a quick look up and down. Let me tell you, at 14 you know how girls already seem to be filled out these days.
At 5’7” and 120 lbs she had it just where a lot of young girls do, round tits (about a B cup) a flat belly and just the right amount of meat on her thighs and her plump ass seemed like it was about to burst through that bikini bottom. She has long dark brown hair with large soft brown eyes, and she was nicely tanned.

I was about to go crazy and couldn’t wait to get in the bathroom. I was going to be a few minutes so I told sis to go on to the pool and I would be there shortly but she insisted on waiting. Fortunately I had my bathing suit and t-shirt on my lap covering my hard on. I got up, mindful to hold my clothes at waist level and went in to change. I needed to jack off so bad but no matter how much I insisted she wanted to wait for me. I tried to get my mind off of sex and my hard on subsided. We spent the rest of the day swimming and looking around the resort had dinner, etc ending the first day.
I wasn’t looking forward to the night because I typically jack off to go to sleep and that’s after typically doing it in the shower not to mention waking up in the middle of the night most times to relieve myself again.
After doing the usual sitting around the campfire thing we all went to our cabins. My sis and I talked and watched TV then tried to go to sleep. My plan was to lay quietly and when I heard her rhythmic breathing that signaled sleep then I would try to quietly relieve my aching dick. It was quiet so I started to slowly stroke myself with my back turned toward my sisters bed. I knew the covers would rustle just a bit but hopefully not enough but just then my sister said “you can’t sleep either”, SHIT I said under my breath and answered NO.
