soooo goooood" she cooed. She had started to smoosh her legs together as if scratching an itch on the inside of her thighs and started to wiggle her hips at the same time. "Ï can make you feel even better if you like, brittney" I suggested. "How?" she asked. "By touching you in other places too" I responded. "Like, here" i declared, and placed my hands over her pussy, sliding my fingers in between her legs along the fabric of her dress. "Mark, you cant! I'm your sister!" she exclaimed. "you sure as hell don't look like my sister at the moment. Doesn't that feel good sis? I only want to please you, I wouldn't tell anyone." i responded. "Well, so long as you don't tell anyone, I guess you can proceed."she replied. I continued to slide my hands between her legs, massaging her pussy through the fabric of her panties. After a while, I started to slide my hands over her thighs, teasing her, knowing it would drive her mad... "Mark, that feels so good... Don't stop, please..." she pleaded. "Don't stop doing what - touching you here?" I asked as I placed my hand yet again over her vagina. "Yes - Yes - keep touching me there please!" she pleaded. "I could make it better" I suggested. "Better? How?" she asked. "I could remove your dress, maybe even your underwear" I replied. "Mark, we can't. I mean, we are brother and sister! Its not right"she declared. "Well, you aren't my sister at the moment, are you? You are Katherine, a girl from my school" i responded. "That's true. But you are ... still Mark AND my brother" she pointed out.

"Well, there is someone I like. and I did manage to swipe one of his hairs. But you would have to promise not to tell anyone, Mark." she requested. "You know I wouldn't, Brittney. We can keep each others secrets. Now, would you like to get that hair?" I asked. "Ok. I guess I can trust you." she replied. She went to her room to retrieve the hair. I was almost beside myself. I was about to have Katherine - the girl of my dreams! And it was my sister at the same time! I couldn't believe my luck. I had never imagined that it would lead to this when she walked in the room, bet yet here I was... "Here it is, mark" Brittney said, handing me the hair. I took the hair from her and dropped it into the potion vial. It went a reddish colour. I drank it off. I felt the familiar bubbling for the 3rd time so far. I saw her Brittney's eyes widen as I turned into the guy she liked. He had dark ruffled hair and a lightning shaped scar across his forehead. Some things that girls are into are so weird... "well, where should we start?" Brittney asked. "I think we should kiss" I replied. "But, you're still my Brother, Mark"she replied. "What do your eyes tell you, Brittney?" I asked. "That Harry is standing before me" she responded. "Well, Kiss HARRY then" I said. "Ok, I think I will" she replied. With that, she moved ...
