I love my sister

And not in one of those innocent familial ways.  Every time I see her come out of the shower, I want to follow her into the bedroom, throw her on the bed, and make sweet fuck to her all night long.

Is this normal?  What should I do about it?

i wanted my sister that way also;
what i was doing back in the day, to not rape her was, after she showered after work, i waited a while enter the bathroom grabed her dirty working pantyhose, sniff and lick the foot area and lick and sniff the hose that cover the pussy ,grab one leg and round the hose around my shaft and start wanking when i was about to came
pull out and spray all over the toilet, believe me it feels like if you are fucking her; other Technique its more risky grab her dirty pantys siff and lick the pantys and proceed to jerk off it feels even better but the 4 times i did that, i end up coming to quick and make a mess in the pantys, and i barely clear the tracks, lucky to me she never find out what i was doing 
when you get a grilfriend and star fucking her you will loose the interest in your sis like i did

btw im italian
my sis was 27 back in the day and i was 17, you will not belive how much i wanted her
