You come home to find your chubby Step-Mother in teeny tiny gray booty shorts and a tight sports bra. She is grunting and struggling as she tries to do some squats and other various leg/booty workouts. She notices you are there and asks if it’s OK for her to continue working out while you do your homework. You say you don’t mind, but really, you are so distracted. Your step-mom tells you she is working out because step-daddy doesn’t pay much attention to her anymore since having another pregnancy. She feels like her body has gotten so fat and unattractive so now she is trying to do some thing about it by working out. She seems quite down about it and keeps pointing out her flaws, but all you see is sexy, fat perfection. You tell your step-mom how hot you think she was and before you know it, you can’t help but to stroke your dick. You’re surprised that step-mom is not upset, in fact, she seems into the fact that you like jerking off to her. Step-Mommy tells you it’s OK to pump your cock whilst she finishes her work out. Step-Mommy starts to put on a show for you, pulling down her tiny shorts and showing off her big fat tits, encouraging you to pump your big boy dick and give your load it to her!
