Unable to think straight, totally shocked by her sudden attack, you repeat the word "transform.." which makes your girlfriend grin ever so mean. "Transform it is!", she answers. "As soon, as I get aroused in your presence, you will shrink down into your penis and then turn into the perfect sex toy for me - a all in one pleasure machine that knows exactly how to stimulate me. You will ferl all the pleasure, but like me as a doll be unable to come. And you will stay that way, until I say, that I am entirely sexually satisfied."
You look at her, still scared. "Listen," you try it, "I really just wanted to tease you a bit. I had the best intentions. Also, you were the one, who lied to me in the first place! .." As you talk, your girlfriend closes her eyes and starts fondling her clitoris and her breasts. As she starts to moan, you suddenly feel strange. The world around you grows bigger and bigger, you feel limp, only your penis seems to firmly stand erect. It als grows visibly in relation to you. You can see the smile of your girlfriend, as you are slowly dragged right into your shaft, everything turns dark and when you suddenly feel her gigantic hand wrap around you and shove you into her warm, moist vagina, a wave of unimaginable pleasure rolls over you.
Your girlfriend pleases herself with you, enjoying your exquisite form, that magically fits her needs perfectly: You have the perfect size and form for her, you have a vibrating patch right, where her G-Spot is and also a clit massager. Also you seem to have a little appendage, that might have once been tour right arm, which she picks up and plugs into her anus instead of the butt plug. Your firmer arm also vibrates in all the right rhythms. You can feel her work you hard and you long so much for release, but whereas you can hear your girlfriends loud moans and feel her muscles tense, as she comes, you are stuck with your exhilarating feeling.
After your girlfriend sinks back and pauses her actions, you prepare to transform back any time now. But then you feel her get back into motion again... This is by far not over. She gives ig to herself a second and third time, before she drags you out and puts you on the bed next to herself. "You turned out really well!" She says, stroking you up and down with her hand, causing you incredible waves of pleasure. "I wish I could have a dildo like this for forever!" she mumbles, then she picks you up again and shoves you back into her pussy, plugging your arm back into her ass. She sighs loudly and says: " Oh gawd! This is so much better than what a real dick could do!" She is quiet for a moment, as she realizes, what she just said, then she makes the one biggest mistake she could make, as she speaks: "Of course, a dildo like that could never replace your human self in bed, darling!" She moans and before she even knows, her last sound fades and she is stuck again as a silicone sexdoll, all set up with you inside her, pleasuring her beyond comprehension. Her mindless ahegao look going off into infinity - an infinity of you both pleasuring each other with no hope of relief for either one if you....
The End
