b*****r Caught Out!

I was on my way to college, when a friend text me to say that the lecture that I was going to attend had been cancelled. So I made my way home again, Mum and Dad were both at work son only my younger b*****r was there having just left school but out of work, usually in bed til the afternoon. Well this day I was in for a shock not only was he out of bed he was up to no good in my bedroom. I let myself in and walked up the stairs, I noticed Mark bedroom door open and he was not there, as I walked towards my room I hear movement in there, I popped my head around the door and couldn't believe what I saw. Mark had some girly magazines layed out on my bed he was knelt in front of them with a pair of my dirty knickers held up to his face. He was naked and I looked down and saw his arm moving up and down. I was behind him so he did not see me walk in. 'What do you think you are doing' I shouted out. Mark jumped out of his skin, he didn't know what to do he tried to cover his privates and hide my knickers behind his back. I called im all the dirty fuckers under the sun and threated to to Mum and Dad on him when they got back from work. He begged me not too. I looked down at his pathetic skinny body and thought I could have some fun here. I told him to stand up and hand me my knickers and to place both hands on his head. He did as he was told though reluctantly. Wow he had a stonker of a cock, the end was all wet with pre-cum and a good six-inches long with his balls all tightened up. I told him to pull his foreskin back and show me the glands. I had good look at his cock and still a virgin from what I know. 'you like smelling my pussy do you' I asked hold my knickers up against his nose. He nodded with shame. 'wank yourself off in front of me' I ordered. He started to do this, I have to admit I was getting aroused too and my pussy was getting very wet inside my knickers. I then did something that shacked myself. I lifted up my skirt and showed my my knickers, I rubbed my hand on my crotch for a rubbing my knickers into my slit, making them wet with my love juices. I then pulled my skirt down a little to cover myself and then pulled my knickers down and stepped out of them. I then held them up to Mark's face and let him smell and taste my fresh pussy juices. Mark wanked like crazy, I looked down at his cock, his hand was just a blur around his throbbing cock. He then let out a cry and and spurt of hot spunk shot out at hit me on my thigh before I could get out the way, the rest shot all over the carpet, the smell of Mark's sperm filled the air. I looked at Mark and his wilting dick and told him to get out of my room. He quickly went to his room. I was feeling horny as hell and looked through the girly mags and gave my clit a good rub and wiped the sperm from my thigh and had a taste, this had my cumming in minutes. xx
