Is it normal to wanna have sex with my aunt?

Ok so here's my story guys.
I'm a 18 year old guy and my aunt is 27,we are close to each other and live in the same house.
We sometimes sleep in the same bed when we have guests.
But a night we were both alone and we slept togheter because the guests arrived in the morning.
So I was there thinking about having sex with her,my uncle went for the guests so I started to masturbate watching her ass while she was sleeping,the bed was shaking a bit ,I kind of touched her ass with my penis for pleasure.
So I almost finished masturbating when she woke up and thought that it was an earthquake,I was faking sleep and she woke me up and asked me if I felt it,I said no however.After that I didn't finished masturbating and fell asleep. The next night we had the guests so I slept again with her,I was thinking about touching her boobs and I done it,I could feel my instant boner after touched them so I start to masturbate again,when I finished I decided to cum on her ass(the pants) so I did it and I shot a big load onto them and really liked it,I knew they will be dried the next morning.Ok so the next day I was just looking her and she said:I need to be more careful when sleeping I think I pissed on my self last night,I found them wet.I was frozen looking at her,I thought:She found it out,and I said "maybe you had a bad dream".The next night I slept in my room alone and was thinking about her ass and boobs when I got a boner,then I put in some porn and start masturbating when she entered the room to get some stuff,when he did it I just stayed there for like 10 seconds watching at her embarassed face,then she said:Omg I'm so sorry,smiled and closed the door,then I could hear her moaning while pleasing herself with a vibrator.What do you think guys,what could I do to have sex with
her?
