IIN that im sexually attracted to my sister?

Did you use to take baths together when you were little ?
Or do you take showers together nowadays ?
Has she ever seen your naked cock ?
Do you walk in the bathroom when each of you are in the shower or on the toilet ?
Walk in the bathroom naked when she is in the shower and peel the curtain away and ask her if you can join her and she will stare at your cock and she will probably say , sure , come on in.
When you get in the shower with her wrap your arms around her and start kissing her and feeling her up and suck her tits and work your tongue way down to her bald cunt , pink clit and ass cheeks , ass crack , poop chute and then stand up and she will start stroking your cock and massaging your nut sack and then she will blow you.
Make her swallow your load.
Then drop the soap on purpose and tell her to bend over and pick it up and when she does , slide her the bone in her booty hole and in her twat and make her cum.
Pop a nut in her ass so she doesnt get knocked up.
Unless she is on her period , then you dont have anything to worry about , then you can cum inside her cunt.
