Cousin Thought I Was Sleeping

So I (male) went on holidays with my cousin (female) and her parents. Due to misunderstanding it ended up with her parents in bedroom and me and her in living room sleeping on sofas.

For days, my cousin and I enjoyed the pool and heat, she spent most of the time in a very nice bikini that showed her body vey nicely. But she also seemed to walk into room while I was changing or would be less covered around me. In the pool she would be very close and I'm not going to lie, I was grateful the water hid my hard-on.

One day she decided we should use the steam room. In we went with the room to ourselves. After a bit she decided the bikini needed to go and she would have just towel around her. As we messed around the towel fell revealing her naked body which was absolutely stunning and caused an instant hard-on.

Not long after her parents called as we needed to go for food. All through the walk to the restaurant and while eating, all I could think about was her body.

I could do nothing about the state of my dick so tried to hide it until everyone was sleeping where I could deal with it then. Bedtime came but I was in for so much more than I thought.

As I lay there, I noticed that my cousin wasn't sleeping, her legs were open and I could clearly see her hand moving along her pussy. It was dark but there was plenty of light shining in to let me see the fact she had one hand fingering her pussy while the other was squeezing her tit.

I could smell her wetness. I could hear her breathing get heavier and my mind was full of the imagine of her naked body from earlier.

I was now so horny pre-cum was all over me. I started to squeeze by dick while watching and listening - as she got faster and her back arched. I knew she'd cum and now I needed too. I got up and walked passed her to the bathroom, leaving to door open and wanked there on the spot. I don't know if she watched or not but I gave her every chance to. Within a minute I came into the toilet. Cleaned up and went back to bed. 

I thought it was a one off, until the next next when the same thing happened again....
