Your step-mom is finally taking the holidays she's always dreamed of. She's a bit stressed leaving you home alone for so long but she trusts you. She's acting a bit strange though.. she seems like there is something else on her mind. But you can't quite put your finger on it, so she kisses you goodbye and tells you she's coming back like a brand new step-mommy! Finally the day comes and she's home. She's overdressed though, it's definitely not that cold out. She admits she wasn't.. completely honest with you about her "vacation". She didn't entirely go on holiday, she felt embarrassed since you're her step-son to admit it but she can't hide it anymore. She got a step-mommy makeover. A boob job. And she wants you to be the first to see! She puts her hands over your eyes and when she removes them .. just.. wow. Her boobs are.. Massive. Huge. She barely fits that summer dress anymore. You are speechless. She notices and thinks maybe you don't like them but then she sees the bulge in your pants and everything about her changes. She seems, flirtation? But no, she's your step-mother.. that can't be right. She admits she got these so she could get more attention. She didn't expect it to be from her own step-son. But maybe it's perfect. Maybe it's how its supposed to be. She teases you for so long. Makes you wait for them. Runs her hands over and into her new big titty cleavage. Finally she pulls her dress all the way down and wants you to put your dick into there. Her new tits. Step-mommy wants you to titty fuck her. But it needs to be nice n wet so she sucks you and spits so it slides in perfectly. She knows there's more she wants to experience. She rides you until she cums all over your cock but she knows you still need to cum too.
