Hey i have a really big crush on my little sister. I am 18 and she is 14. She always walks around in those little shotrs and she wears tight T-shirts which just make me wild. I really wanted to see her naked so i went to the window when she was in the shower and looked at her playin with herself. It got me off so well now i really want to have sex with her but i dont think she knows so how can i get her to have sex with me?

Try first to get close to her, you know become her real best friend, make her to trust you in every way, that will make things more easier, but if you want to confess, you have to make it slow so she can understand how you feel and not only think of you as a child molester or worst a pervet, and more important be gentle with her XD
ithink you should see this, it may help you a bit:

You know if it's "right or wrong" "normal or not normal" CASE CLOSED! (pain in the ass)
i was 16 my cousin was 10 and i felt her up in her sleep. then i whipped out my huge boner and pulled down my pants and turned the TV up so she woke up. keeping one eye barely open, i could see her eyeing my cock. i wish i woulda gotten a nice ass blow job but my plan didnt work.
7 year old? just play a game with her and "accidently" drop a toy on your dick a couple times. eventually, she will feel it and be like, "what the fuck?" and give a an amueture hand job.
worked on my other cousin... lol ok
