She doesn't give you a choice--hey, you asked for it!
From Create Your Own Story
Before you can decide whether to beg for even more or ask for mercy, Callista decides for you. Shoving you flat on the bed, she rises into pushup position and lets gravity drop her right into your ass. You wail at the feeling of her huge cock being stuffed in too fast and try to move your butt and legs to make it more comfortable. She responds by using her shins to hold down the backs of your knees right where she wants you. "You asked for this," she reminds you. "You wanted me to make this ass mine. Well, that's what I'm doing. Shouldn't have asked me to stay in your ass if you didn't want this." You lie there face down in the pillows, moaning and whimpering as she bounces up and down on your back, making your ass jiggle as she falls down on you. After excavating you for another 20 minutes, she demands, "Whose bitch are you?"
"Callista's bitch, I'm Callista's asswhore," you sob.
"Say you love my cock."
"I love your big black cock!"
"You gonna take my dick again after this?"
"Yes, as much as you want!" you cry out.
"Damn right," she tells you. She drops into you harshly once more, then pulls out and sits back on her heels, still pinning your legs. A fountain of cum splatters on you in a line from your ass to the back of your neck. You moan and wriggle on the bed as she continues spraying you down with thick, hot spunk. You know what's coming next, because she made you promise her. She uses her cockhead to push some of her cum into your anus, then goes back to fucking you. She sodomizes you and paints you with her cum over and over, each time forcing you to promise her more. Finally, you don't have to be prompted, begging her to do it again even as she is still ravaging you. She cums one more time, leaving you a goopy creampie.
"Holy..." she huffs abortively. You can only muster an agreeing grunt as you finally relax and feel her cum start to leak out of you. She holds you in her arms as you both settle your breathing. "Wow, hon, you are one incredible fuck. I don't think anyone's ever taken that monster like that before, especially not a virgin!"
You turn to look at her and say "You own my ass as often as you want from now on. I've never had anyone make me feel that good. I'm glad I tried this experience with someone like you first."
She smiles shyly, which seems a little incongruous with her recent treatment of you. "Hey, I might have to take you up on that promise," she says happily. "But not anytime soon. It's gonna take me days to sleep this session off!"
You agree, and fall asleep that night looking forward to more shemale fun in the future.
THE END
