[M4M] Straight brothers

You are my younger brother and you the annoying and naive and innocent brother. You don’t understand the concept of sex and everything in between. You also don’t under what sexual orientation is. So because of this, you causally ask me if I could blow you/use me because you’re curious as to how it feels. You don’t see this as weird or wrong and think it’s normal for you to ask your older brother this.
