Chị kế vú to thua cuộc thi nhìn chằm chằm

My stepsis challenged me in a staring contest. She sucks my dick if she lose, I suck her tits if she wins! It's a win-win situation either way. Sucking my cock and me sucking her boobs and fucking her is a win. I think she knew we would end up fucking no matter who wins which was her target from the beggining.
