Would he agree?

I wouldn't suck his dick or do anything else for him. Being my brother that would be weird but I would keep letting him eat me out. I could just lay back and close my eyes, but I would never let it get further than that.

I bet he would fuck you

Sure if you're going to let him eat you by all means you should suck his balls dry.

You should not be selfish and return the favour, git in the 69 position and dont be mean

It took my sister a few months but she decided one day to return the favor.

It's wrong but if were speaking truthfully, yes you should

Yeah. Suck his balls slowly and long and he’ll eat you eat whenever you want

Yes definitely and then let me know how it goes
