Friend‘s Sister attracting me

It is actually cheating, don‘t complain about the tag 🤣.. cheating to a bro is cheating

But a friend of mine got a very cute and hot sister, which shows herself pretty slutty off…. and fuck I wanna cum on her so bad, even though she‘s a no-go for me, but I just know I‘m so naughty.
And its actually true.
I meet so many women in my life, and so many attract me.. like woww!
Especially thicks and petites.. (are there even women I can‘t like??)
Literally you could show me any girl, and I‘d get a story what I‘d do with her 😭 am I a pervert?

I feel so bad though
