Your new step mom who just married your dad that is a high level VP of sales for a big company starts to fatten you up as revenge for treating her poorly and being annoying when she got your father to kick your mother to the curb. But you are an incredible submissive feedee and get off on it. She discovers this and begins to fatten you tremendously. Initially it starts as your gut ballooning, no weight anywhere else. Then, after your gut becomes a basketball sized blob of blubber on your torso, you start to expand in other areas. As she fattens you, your ass blows up too, making you look rather feminine. Your fat thighs make you waddle. Finally, very feminine moobs start coming in. Your step mom has had enough of the foreplay and demands you prepare for her. She tells you to gorge for a week straight, eating constantly. You become constipated and being too stuffed cannot go to the bathroom, growing even faster, expanding everywhere. She pushes you and extends it to two weeks of constant feeding and stuffing. Then when she finally takes off your clothes and lets it all out, keeping your undershirt and underwear on, acting like a bra and panties. Your gut is so swollen and massive, but your ass and tits are huge as well. Then she demands you eat even more for her.
