Erica Doll used and fucked by jealous big step sister

Stepdad always does a favor to Lilly. She gets new clothes, new jewelry, a riding academy even a huge real doll, who do everything that she wants. Till I showed her how to please stepdad, how to suck His cock, lick His ass and balls, they spend all their time together. I feel totally lonely, my stepdad didn't use me for 2 days. Im so fucking horny, but the vibrators cant satisfy me. I will get stepdad back for myself! But before that I will "play" a little with Lilly's new Erica doll...
