I feel sick at the thought but here we go.. Basically, my Uncle recently turned 50, so all of them family went to stay in this posh Hotel in London. I hadn't seen my two Cousins Tom and Luke for a bout three years. Luke and I were both 16 and we used to be really close, but time seperates you. Me and the rest of my cousins were sitting in the lobby when my Uncle walked in. Everyone clapped and cheered but I was just looking for Luke! MY Auntie Jane walked in with two tall good looking boys. They were my cousins. Luke looked so fucking hot! I just stared at him for ages, until he clocked onto me and came and gave me a massive hug. The rest of the evening we were inseperable and didn't really bother with anyone else. We'd both had quite a lot to drink by the time everyone went to there rooms. We went and sat outside where I had a cigarette but as I began to spark up, he took the cigarette out of my hand and kissed me. I was like what the fuck are you doing? We're related?! But he said he didn't care he thought I was 'peng'. Even though he said 'peng' it did not stop me from having extreme sexual urges for him. We started kissing, until my Auntie came out for a cigarette too. She said the adults were going to a bar down the road, and would me and luke mind looking after the younger ones. Free room, why not? Unforunately my 14 year old sister and 15 year old cousin were still awake when we went upstairs. So we both said we were going for a cigarette and sneaked to my grandparents room, as they were out with everyone else and they said if we needed to 'escape' we could use there room. We sat on the bed and started kissing again.. I pulled away as I realised we were related, this was illegal right? frowned upon in soceity? but he said he didn't care.. it's just sex. I didn't love him at all, but I felt a strong sexual urge to have him. So we began kissing again, he kissed and bit my neck. I was so turned on. He took my dress off and slid his hand into my nickers and started to finger me, I then stopped again. And said how this didn't feel right.. and I couldn't do it anymore. I pulled my dress up and tried to walk away but as I turned back, I saw his raging boner which turned me on so much. Fuck it, I ripped off his trousers and shoved his dick in my mouth. I played with my hair and then pushed my head down onto it hard. I pushed him back onto the bed and sat on his dick. We were at it for a good two hours, but keeping an eye on the door. As I swallowed, we could here my grandparents coming up the stairs with the rest of the family. I sprinted to the bathroom and Luke pulled up his trousers and switched the tv on. I emerged normally and my grandparents didn't suspect a thing. I still feel strange when I see Luke but we talk and make a joke about it. Hhahaha, glad I got this off my chest!
