We didn't expect a visit at all, but my mother's sister came to town to solve some urgent business and she took with her the entire family, including my cousin! Of course, we didn't expect this and there was not much space for them, but we did our best to accommodate our guests. That's how I discovered that I have to share the bed with my cousin, and it was a bit weird, because we haven't seen each-other in a long while... Now we're both young adults and I don't know him almost at all, he grown up so fast and turned into a handsome young man, I remember him as he was 5 years ago, a nerd with no social life. We didn't get along very well from the beginning, he entered the room while I was dressing and I think he saw something that he shouldn't have, like my Big Boobs! I told him it's ok to share the bed, but I want to go to bed immediately, because I have an important exam tomorrow. I was kind of tired, so I went under the moment my head touched the pillow, it felt very comfy and I didn't think much of my cousin, who was lying next to me. I woke up being touched inappropriately and when I took a look at him, he was full hard and masturbating! It would normally upset me, but this time it was interesting, mainly because he had such a big cock and because he's my cousin, and these sort of things are forbidden between relatives. I touched him and he shivered, I wanted to feel his hardness with my hand, and he touched my pussy, slipping a finger inside. It did not take long before we started fucking, I was too eager to feel that cock inside me! We spooned a little, then I went on all fours, doggy-style, my favorite, and I came really quick. Then I rubbed it some more, put it in my mouth a bit and DeepThroated it, we had sex again and I had a very powerful orgasm, the second one for today and, finally I made him cum in my mouth by jacking him off and edging him. We totally decided to repeat the experience in the morning!
