You catch step-mom getting ready for work and notice she's extra nervous & on edge. She's going up against a lot of younger women for a promotion at work and wants to catch the boss's eye. She knows he's an ass man so she's bought a thong girdle to really make her ass pop. She's feeling insecure until she notices how hard seeing her ass has made you. She know it's wrong, but she's so flattered she can make a hot young man like her step-son hard she can't resist teasing you & encouraging you to blow a big load all over step-mom's ass!
