I want to lick my cousins feet again,normal?

hi
ive always thort my cousins feet were sexy but when i thort about licking them it just seamed so good.
so i was trying to edge her towards allowing me to do it.
one day when i was 14 and she was 15 we both got really drunk and she was pretty much passed out and in my drunk state i thort now or never so i said to her im going to clean the room up then coming back and i am going to lick your feet,she just grunted so i said it again and she just moaned which turned me on a lot,she was not moving we were both lying on the floor so i picked up all the bottles and before i went to chuck them away i licked a little and sniffed but i cant remember a lot of what it was like :(
so i took the bottles away and came back for more fun but she was awake now and said lets go to bed.
ive tried to do the same thing again and have gotten close,once (when we were drunk again) i was saying how much i love to lick girls feet and that they like it a lot,then she told me about some money she stole and i said im telling and she said dont and i said what do i get out of it and she said anything i will do anything for you.
i really wanted to say lets get your feet out right now and i will give them a proper clean with my tongue but i was trying to get her to offer it to me so i wouldn't look like a fool.
we have even talked about us having sex before,we have said who would u rather do and stuff and when i was saying u to her a lot at the end of it she said it wont ever happen anyway,and i said u never know and she said well 'yeah it might do :)'
so i want to know is this normal to do these sorts of things with your cousin,its not like were getting together and having a messed up baby and stuff,its just harmless fun :)
thanks
