Slow Changes

You are broken but when you get to bed Sam fucks you one more time unloading into your tight asshole one more time. Your ass is so totally full of her cum at this point your belly has swollen and it is leaking out of your asshole but Sam doesn't care as she pulls you in close to be the little spoon her cock pressing into your back disturbingly. You wake in the morning to Sam grabbing your ass, "See honey I just need to fuck the boy out of you" She says. Getting up you both look at your body in the mirror and you feel shocked. Your ass and hips are much larger and firmer now, and the rest of your body thinner except for your chest. You seem to be developing breasts but right now they are just lumps. Your face also looks smoother and your hair longer but that isn't the worst part, your cock is now tiny and you feel humiliated as Sam stands behind you pressing her cock into your ass. "Ooo I like this but I think we should get you a new look," Sam says eagerly. When she hands you a set of pink panties you hesitate until she stares you down into submission. Over that she has you wear a short sundress like she had taken to wearing recently.

You hadn't even had time to look at yourself in it before Sam pushed you onto the ground and pushed aside your panties before she started fucking your asshole. You realized she just dressed you up to further make you feel like a girl. Even worse than that her cock feels better than it ever has before and you realize you are getting into it. "My look at the little slut," Sam says pulling your hair back and forcing your head up so you were staring into the mirror watching Sam fuck you from behind. "Do you like it" Sam asks and you just moan "Good now I want you to repeat after me. Cum inside me please I want your babies". Instantly I repeat her words and say "Cum inside me please I want your babies". Sam had a huge smile on her face like her dreams were coming true but said "Good now keep saying it slut until you believe it." Sam kept fucking you for hours making you repeat the phrase over and over again until it was engrained into you and you said it automatically. Sam fed you nothing but her hot cum the entire day and didn't let you wear anything but the increasingly cum covered dress either.

As you fell asleep slowly you kept repeating "I want your babies" and "Cum inside me" over and over

Sam fucks you less the next day but keeps up a steady training schedule fucking you morning noon and night in addition to when she feels like it which is often. Sam has started to change as well becoming taller and stronger. Beyond the physical changes, she is way more dominant clearly but her libido has also skyrocketed. You would be lucky to get her to have sex once a week but now she is as horney as a teenage boy and won't take no for an answer.
