Slides his pants down

You watch Brian as his dick flops out, and he's slightly bigger than you are! You smile, and Brian strokes your ass even more rapidly.

Brian starts jerking his cock slowly as you can't take your eyes off of it.

You then remember the deal...and tell Brian to lie down as you turn Tyler around.

You straddle yourself over your friend's face as you pull Tyler up to you and run your tongue over his ass.

You feel a wetness against your asshole, and Brian goes a bit further as the tip of his tongue slides into you.

You moan loudly as you slide your tongue into Tyler and begin licking up and down inside his asshole.

As Brian continues to eat you out, you pull out of Tyler and give in.
