During overtime, I couldn't help but get aroused by my big-assed married female boss's tight ass, taking advantage of being alone with her in the office. I thought she'd be angry if she caught me, but instead, she asked me to touch her ass! I obliged, massaging her big ass, and then she guided my hand to her anus! What?! She likes anal?! She then asked for anal insertion, something she couldn't do with her husband, and climaxed multiple times through her anus. Her tight pussy trapped my cock, resulting in a satisfying anal creampie! From that day on, every overtime session became a chance to massage her big ass and have illicit anal creampie sex.
