I'll admit I can be a sick individual at times.
But I wouldn't use the word arousing, like Don Cardi said earlier Sonny was a lot nicer than I would've been.
I don't have a sister, but I have a cousin whom I treat like a sister(we're that close) and I've told her boyfriend that if he hurts her in anyway, he'll have to deal with me. And I won't be very kind.
