Looking round the room I saw her phone, she must have left it behind, if she could forget that maybe she could have forgotton to hide her dirty underwear.And I was right, in the middle of the floor was a small lacy pair of her underwear. With this in mind I sneaked into her room. I thought that possibly if I found a pair of her panties they might have some of his jizz left on them. Dan had been round the night before and I was pretty sure they had been fucking. However when sitting in my room hopelessly jacking my cock, I realised something. In the past I had used to go into her room and steal panties to wank with, this became a habit until she almost caught me one day and I stopped doing it. My sister had gymnastic lessons and would leave the house every thursday and leave the house for 2 hours. My parents were out at work for most of the day so there was no end to their love making.
Dan kept apoligising about this but slowly our friendship was lost as each time he came over he would always end up with Katrine and seemed much more interested in fucking her than playing ps3 with me. I often had incestuous thoughts about my sister coupled with my lust for Dan, it was unbearable. I was infuriated, not just at the betrayal of him going out with my twin sister which I had always forbidden, but jealous of both of them. Since then they have been dating each other and even started having sex. I had left my room to go to the toilet and came back to find him kissing my sister in the hallway. We were both drinking and I thought possibly we might get drunk and something would happen, it did, but not with me. It was new year and I had invited him round to my house where my family were hosting a party. However I was never man enough to attempt anything, fearing that it would ruin our friendship. I had no interest in being in a relationship with him I just wanted to feel him dominate me. Even writing this now I've gone rock hard at the thought of him. To feel every inch of him and have his warm seed in my mouth and face. I lusted after him, I wanted to feel his hot rod penetrating my tight anus. However my cravings for him were different. I've always thought I was straight and I've had many girlfriends who I've fucked and particuarly enjoyed fucking. We've known each other for years but recently I've been having urges and desires towards him. I have a best mate called Dan, he's the same age as me, brown haired and very attractive. And this is how I used that to my advantage.
I have a twin sister Katrine who apart from being a girl looks extremely similar to me, she even sounds the same. My names Joe, I am 16 years old, blonde, quite skinny and not particularly muscular.
