Residing in the fact that your new boyfriend is so much stronger than you, you just decide to give into your new feelings and see where this takes you.
"Ok... I give up, you can show me what you wanted me to do when I still had that..."
Your boyfriend grins at this and says
"oh boy! I can't wait!"
He then practically picks you up off the floor and throws you onto the bed, you nearly hit your head into the backboard but just narrowly miss it. He then jumps on top of you and is so excited to fuck you but you stop him before he can put his new dick inside you and you say
"I want to start off slow tonight baby, this is my first night as a woman after all".
You see him frown slightly and he agrees to your request
"ok what did you have in mind?"
You think on it for a second but with this new body and your new desires driving you you can't help and say
"hm well maybe we could try anal tonight?"
He beams at this idea and says "yes of course!"
he then proceeds to flip you over exposing your rear entrance and he readies his cock. Just the feeling of his member brushing up against your bottom sends shivers of pleasure coursing through your body and you leak some fluids from your nether regions and he asks "you ready?"
To which you reply with a firm "fuck yes!"
and with that he then penetrates your anus and begins pounding you so hard you can't help but squeal at both the pain and the pleasure you are receiving. It does not take you long to get used to the rhythm of being pounded and you then begin to shake foreword and back in time with his thrusts allowing his member to seep even deeper into your anus.
He then starts to grunt so loud you think he's going to burst at any moment and then he finally does and he fills your waiting ass with so much cum it backs up into your stomach and makes it bulge like a water balloon. you loved the feeling so much you failed to notice your old personality beginning to slip you then start thinking to yourself "why the hell am I doing this!? Why don't I just run away and find help? have I really always just been some horny bitch in heat at heart? Or is there still some part of my old self still left anymore?" suddenly another more commanding thought fills your mind. "You know you loved it, just give into your lust completely and let me take over!" you nod to yourself at this thought but then quickly shake your head no and shout "NO! IM NOT GOING TO GIVE IN THAT EASILY! IM A MAN DAMNIT!" But then you feel your boyfriend begin to fondle your breasts and your thoughts get even fuzzier.
"You know you love this new body way better than your old one, just give in and reside yourself to your fate".
Just then your boyfriend kisses you passionately and any conflicting thoughts you had melt away and you submit yourself to your fate. Your boyfriend then starts chanting and you feel something shift but you don't need to know what he said to understand what he did, by some gut instinct you know that he made the changes you've both endured so far permanent and no amount of chanting would ever change them from what they were now anymore. You then turn to him and smile at him seductively.
"I think I'm ready for the real deal now" you tell him and his face beams.
"I was hoping you would say that!"
He then climbs on top of you again as you lay on your back this time and before he enters you one last thought passes through your mind
"this is what I've always wanted!"
