Your Stepmom comes into your room furious. You STILL haven't done the dishes, and moreover, she catches you sitting at your desk gooning! She launches into a verbal tirade, pointing out how lazy and unmotivated you are, talking about how she would never be so useless just because she happened to have a dick. Besides, there's NO WAY stroking could actually feel THAT good, right? She leaves furious to talk to her friend on the phone, and tells you that she'd better not have to have this conversation with you again. But, while on the phone with her friend, something happens. She starts getting a strange feeling in her pants, and she can't seem to stop rubbing herself over her jeans. She unzips and finds that somehow, she's grown a HUGE cock, and it's becoming irresistible to touch! She starts stroking her cock, surprising herself with her moans. She's embarrassed and confused, but again she notices that the chores haven't been done. Promising to teach you a lesson, she storms back into your room. Immediately, you can tell that something is wrong with your stepmom. Even though she's still pissed off, she's behaving strangely and keeps looking over to your computer screen where your porn is playing loudly. As she starts trying to tell you off again, that irresistible feeling comes back, and she starts rubbing her growing cock through her pants. Soon, she's stroking her hard cock in front of you while begging you to help her to be normal again by making her cum, and gets down on her knees in front of you to see your cock, too. Before you know it, you're rubbing cocks with your stepmom while she moans like she's never been this horny, dirty talking you about what a goonslut she's turning into. Finally, she stands over your desk and jerks off while watching the same porn as you, cumming all over it and finally accepting that she was wrong to get on your case when gooning feels THIS good! She thought that one orgasm would be enough... but it becomes immediately apparent that all this did was make her hornier. You have a long night ahead with your new futa stepmommy...
