Late-night office overtime becomes pure lust in “fat mistress”. The elegant boss lady locks the door, hikes up her pencil skirt, and straddles her desk chair backward. Stockings frame her dripping core as she grinds against the leather in “fat mistress”, then reaches for a glass toy. Watching it disappear inch by inch inside her in “fat mistress” is mesmerizing. She rides hard, breasts bouncing free from her blouse, until she squirts all over the chair in the explosive climax of “fat mistress”. Professional decorum never looked so deliciously ruined.
