Is This Normal?

Ok so I figured this question could go in here.
Anyway
So, one of my best friends has a sister, and she is, smokin hot, off the scale. I was round the other day she came in in a crop top type thing and I had to hide my boner. Most of the time, when im there, I imagine me and her, doing things, like having sex and stuff(She's older than me so its not paedophilic, shes 20 something). Last time I was round, she came in and said that she was just getting changed, I went to the toilet looked at her door and was so tempted just to walk in. I had a daydream the other day that I went in her room and she was there on the bed wanting me, then we had bunga bunga. But I cant control myself, I know that ill never go out with her due to the fact she's my best friends sister and that she's older than me. But when I go round I just cant help myself looking at her and getting a boner if she's in something sexy or tight. She said that I was her favourite of her bro's friends which turned me on(weird I know)
So I just wanted to know, is this normal?

of course is normal.It's normal to see someone older and just stare at her/him :) if he/she is so sexy.The fact that its your best friend's sister might be weird but you'll get through.
