(Thank you for all of your comments they have really helped me to finish this story, even if the length was quite short. However, if you stick with me I will attempt to make them a lot longer.)

Sam fell back towards the floor of the tent with the force of me colliding against his body. Our mouths were connected once again, tongues fighting for dominance. Sam grinded against me, making me moan into his mouth as we were still duelling. The sound seemed to shock him for a second, for he stopped the grinding, but soon started up again and found a rhythm, which I managed to match thrust for thrust.
I felt Sam's hands moved from where they had caught me around my back slowly down towards my shorts. Slowly, oh so very slowly, he slipped one hand under the waist band of my shorts and panties and started to knead my backside. This movement made me so horny that I became unaware of everything, but the points at which our bodies were connected to each other. Unfortunately, I was so unaware of my surroundings that I didn't hear the zip on the tent go down.
As soon as I heard a gasp I jumped off of Sam and whipped around to face the door. And standing there, in the entrance to my tent, was my little sister, Cora. She looked so shocked to find me like this with Sam that she was frozen to the spot, just staring at us. I quickly glanced back at Sam to see how he was taking this development and realised that he wasn't wearing anything to cover his cock. When he made eye contact with me I nodded down to his erection with my eyebrows raised to make sure that he was aware of his state of undress. Sam quickly glanced down and while turning bright red grabbed a random blanket to cover his dick with.
"Cor, look it-", I started.
"I don't want to know, Kate. I do not want to know, but I only came in here because I can hear you all the way from my tent and with all the groaning...I thought someone might be hurt," she glanced down at Sam holding the blanket over his crotch and quickly moved her eyes back up to mine, but not without stopping to glance at my exposed breasts first. "Obviously I was wrong. So I think that I'll be going now, but be warned that if I can hear you then Richard and Judy definitely can, so be quieter. Er, bye." She said with a wave as she quickly escaped out of the tent, doing it back up on the way out.
I contemplated going after her, but then realised that I couldn't go out there half naked and if I took the time to get dressed I probably wouldn't catch up with her before she arrived at her own tent. Instead, I sighed and plonked myself onto the floor of the tent, putting my head in my hands. Sam, seeing my distress, immediately came to comfort me.
"It'll be fine, Katie. Don't panic about it, she won't tell anyone, you know she won't." He consoled.
I nodded my head; for I knew that to be the truth, Cora wouldn't tell anyone what she saw me doing in the tent, but it would ruin how she saw me. I just knew it would.

As always, at dinner time Sam and I sat next to each other, away from everyone else. However, today was different. Courtesy of our place in the corner, no one could see what we were doing. Therefore, nobody could see Sam's hand travelling up and down my leg, caressing the inside of my thigh, but they could also not see my hand playing with the bulge in Sam's shorts.
As much as I wanted to carry on earlier I couldn't because I just had to find my sister and make sure that she was, not okay with it, but accepted that it was going to happen no matter what she thought. Gosh, that sounds bitchy. However, when I looked in her tent I only found her best friend, Jaz, lying on her bed and when I asked where Cora was she said that she went to find me and never came back. That worried me, but I knew that if she didn't come back she mustn't have for a reason, so I just went back to my now empty tent and stared at the top of it, wishing that I could have ran out after her.
