Every time I saw my brother-in-law I kept noticing the size of his huge cock marking on his clothes, but I always tried to contain myself, that day we went out to see the game and he complained that my sister never gave him the ass and that he had been wanting to eat an ass for a long time.
I tried to tell him to talk to her and he said he had already tried everything and that that day he would fuck an ass anyway.
When I looked down he already had a hard cock, I looked and couldn't resist, I asked him to go home and said I would solve his problem.
