More Changes

After serval days of steady fucking you notice even larger changes. Your breasts have grown large enough to fill a palm and your face could no longer be mistaken as male with it's thinner smoother lines and longer hair. Sam has started making you learn how to put on makeup to even further feminize yourself. What's worse is your cock is completely gone, you are clearly growing a pussy but it isn't there yet. Your hips have widened further to what Sam now calls her "Fuck handles" and your ass is so large almost nothing fits anymore.

One morning after inspecting the changes Sam says "I'm feeling tired today I think it is time you learned how to ride". You have learned to just smile and nod, anything else leads to punishments, besides you love Sam and making her happy makes you happy. Still, when she lays back and commands you to lower yourself onto her cock and ride her cowgirl you hesitate. It is one thing to have Sam slam her cock into you, it is another to do it yourself. Sam for once doesn't rush you through as you slowly gasping for air lower yourself onto her cock. You gyrate your hips and are rewarded with a flood of new amazing sensations. Slowly you use your legs to raise and lower yourself on her cock. Soon you are happily riding away. Sam cums quickly looking up at you willingly fucking her but neither of you slow down. Sam now can stay hard after an orgasm which is amazing but also means she doesn't have to stop. Instead, she reaches up with her hands and grabs you around the waist and lifts you up. You realize suddenly she is strong enough to easily move your weight up and down on her cock without your help. She grunts as she starts to use you as little more than a warm masturbation aid.

Both of you continue to change, Sam had always liked porn but now she watches it on the TV whenever she isn't doing anything. She will just start at an endless stream of it while she forces you to suck her off or ride her cock for hours on end. By now she doesn't even ask, if she is hard and her cock is out that means you should be sucking. She takes great pleasure in dressing you up like a doll from latex, to maid outfits, to nothing but a collar each outfit is more demeaning than the last one.
