I used to fantasize about fucking my sister against her will when I was between 16-21. Was pretty shy as a kid (especially around girls my age) so she was the only girl I was usually around and thus the only one I was ever (privately) sexually attracted to while growing up. Usually the fantasy went like this:
>get her alone when parents are gone, force her into my room
>pin her down, forcefully undress her, and fuck the everloving shit out of her on my bed
>as she cries and pleads for me to stop, I'd grab her hair and whisper dirty shit into her ear like "I own you and your twat now, slut" or "you should be grateful that I love you so fucking much", "This is what you get for making me so horny all the time" etc.
>Stockholm-syndrome her into liking it and coming back for more by her own volition

Thankfully I've always had enough self-control not to let it go past the imagination phase and now I have way more important stuff that actually needs my full attention. But man, the mind of a lonely teenage boy during puberty is very fucked up.
