I’m a perv for my sister

I wanna molest my sister and suck her huge titties

This is a true story and i think i need help. Im the youngest of 3 sisters and this fantasy of mine is about my second older sister. My sister has huge boobs that look like they will bust out of her clothes and i cannot keep my eyes away from them. one night she was staying over and of course she had to sleep in my bed. while she was sleeping i couldn’t control my urge and before i knew it i was rubbing on her body and dragging my hands all over her stomach. i made my way up to her boobs, scared that she’ll wake up but also wanting to do more. i started squeezing her tits through the clothes as she moved a little which scared me. the next day we were talking and my other sister was present, that’s when my sister brought up that i was touching her body in my “sleep.” i told her i may have been dreaming about something, and we brushed it off but i was so scared. then i thought was she awake the whole time, did she like it? i still don’t know the answer. i know she’s a slut like me tho due to some stuff she has done, like opening her apartment door wearing just a light t shirt n no bra. u could imagine how that would look on someone who has big boobs and a dark areola. we’re muslim so things like this are very taboo and me and my mom were shocked at the sight but i very much enjoyed it. her titles bobbled as she walked to go wear a bra since my mom was there. all i know is that every time i masturbate i think about rubbing my wet drippy cunt with hers. i want to force her and rip her clothes and suck her titties and pin her down forcing her to suck my clit as i fuck her tight pussy with a cucumber. i want to suckle on her huge melons like a baby. i have fantasy about fucking her with a peeled cucumber so that it’s more watery, and stick one side inside my own pussy and scissor her. i just want her all the time and i wanna be naked with her 24/7 playing with her pussy whenever i want. i know im straight, i only have these fantasies about my sister but i don’t like women. so what does that make me? i’m so confused. i don’t have romantic thoughts for any other women besides her.
