Every time I saw my little brother’s huge cock, I knew I was lying to myself all those times I said I was going to stop being his on-call slut. I don’t know how he did it, but he made me live for that thing. It couldn’t be that bad, could it? It made me so horny that I was fucking my boyfriend more often now too and he seemed happy about that. What’s so bad about serving my brother on the side?
