Bored and Horny

Snowed in last January with just my sister 23 and me 28. Having been sent to check on the family cabin before a storm front came thru. The cabin had supplies (tinned & dry foods), so we didn't take anything else with us. But weren't expecting to stay long either, we arrived I checked the outside and my sister checked the inside. Then she decided she needed a hot drink, coffee so she started to make us one each. The coffee probably saved our lives, as if we had left straight away and were caught on the road home. We wouldn't be here today, the storm front moved faster than expected and hit the road we would've been on before it got to the cabin. Carrying a stat phone for the remote area the cabin was in. We received a call from our father warning us about the storm approach told to stay at the cabin until passed. With only the clothes we were wearing none kept at the cabin. I quickly got in more firewood to save getting during the storm with both fireplaces lit to warm the cabin along with kitchen wood range which also warm the water for showers. My sister made the beds, and I put my car under shelter. It had started snowing no high wind at first, but that soon changed and I soon couldn't see outside it was a total white out. We kept busy at first making our dinner, but after we had finished and cleaned up. It soon got very boring, we went to our beds and hoped to be able to go home tomorrow. On waking there was no chance we could leave, even if the storm had stopped, the amount of snow we could see meant the roads would be closed. So, we were there for at least two more days, if the storm finished more if it didn't. In all we would be there six days before being able to return home, at least the cabin was warm. Boredom soon became our new normal, my sister decided to handwash her underwear. But having my sister's underwear hanging up and her wrapped in a blanket. Also got me horny, but I didn't try anything. But as time passed my sister redressed, I made a trip outside when the storm eased to stock up on firewood. Barely finishing when the storm started again. Next day my sister again handwashed her underwear and used a blanket for covering again. Same effect on me, but I kept myself distracted by trying to fix cabinet door. It wasn't broken just needed readjusting to stop touching the next door to it. But once it was fixed nothing left, I could do. My sister was also bored and once she was dressed again. We started mucking about, but that was it, we again went to beds and awoke next morning to clear skies. The storm had passed, but all roads closed, my father said it would take a few days. Major roads got done first, our road was minor so would be one of the last to be cleared. Bored and started mucking about a bit, then after my sister said she was going to shower just for something to do. I asked did she want me to wash her back. To my surprise she said OKAY I'm game, at least it would end the boredom for a short while. But things went further than we expected and we ended up fucking in bed together. My sister has an implant so can't get pregnant; fucking became our pastime. Only getting out of bed to eat and shower. Can't remember how many times we fucked, but we both enjoyed the fucking and we experimented. Finally got a call from our father saying the road was being cleared. We left two hours later after another fuck and shower together. Have had sex since, but not as much as when we were in the cabin.
