Wake up to the sound of Titgirl getting dressed

You slowly open your eyes, remembering the sexy events of the previous day. You must've fallen asleep at some point. With a contended sigh, you stretch out on Titgirl's big bed, hoping to have some more time with her enormous breasts, maybe get your dick inside her super-pussy, but she's not in the bed next to you.

"Oh fuck oh fuck oh fuck..." You hear Titgirl's voice from across the room. She's panicking about something, digging through drawers and pulling out clothes.

You prop yourself up on an elbow, planning to command that she gets back in bed with you so you can fuck away the day, but when you do, you hardly recognize the naked girl standing in the room with you. Her face looks like Titgirl's, but a little more plain, and her previously luxurious blonde hair is more dull and pulled into a ponytail. Oh, also, her breasts are tiny. They'd be average by Earth standards, but after a day on this planet, it takes you a second to register that THIS is the superhero you met yesterday and THOSE are her breasts. She still has the same pink crystal collar around her neck, and her T and G logo nipple rings are still there, though.

"Titgirl?" You ask, not totally sure it's the same person.

"Oh, John!" She yelps, surprised to hear you. She gestures toward her naked body, some clothes in one hand. "I guess you can call me Claire now. This is, uh, the real me. Or at least the normal me..."

"Huh... so you're Claire now... but all that stuff yesterday, that really happened?"

"Yes, it did." She smiles at you, looking at your naked body in her bed, and blushes.

"You remember me cumming on your tits..."

"Uh huh..." She keeps smiling.

"But you don't remember what you're supposed to call me?" You grin at her.

"OH! Sorry, SIR." She drops her clothes and falls to her knees, bowing deeply. If she had her big tits, they'd be close to hitting the ground.

"That's better. Now get back in this bed! I'm going to fuck you so hard you'll wish you had your powers!"

Claire lets out a frustrated sigh that sounds almost like a sweet moan.

"John... Sir..." She smiles. "I can't. I need to go to work. I have a big story I need to work on... but when I get back, I want to hear more about your world. I'll tell you about mine! And you can... try out some more of my superpowers."

Titgirl... Claire... steps into a short black pencil skirt, wiggling her hips as she pulls it up. She's not wearing panties. She then puts on a lowcut black tanktop, no bra, and a black keyhole sweater that covers up her collar and her nipple rings but exposes a bit of her chest. She's cute, but compared to the gorgeous fucktoy you met on the roof, she looks positively normal.

Claire takes a seat on the foot of her bed and slides on a pair of heels, then completes her transformation by putting on a pair of thick black glasses.

"Just... stay here, Sir. Please. I promise you, I'll make it worth you while." She reaches back and slides a hand under the sheets, finding your cock. She toys with it in her hand as it stiffens and she begins to stroke you, using her super-grip and super-speed to give you the quickest and most intense handjob of your life."

"Ohhhh Titgirlllll..." You moan, immediately on the verge of cumming.

"Remember, Sir. I'm Claire when I'm not on the job." She winks at you as you climax, blowing an intense load, all warm and sticky, under her soft sheets and all over her hand and your stomach and legs. Claire licks the cum off her hand, letting out an orgasmic moan.

"Promise, sir? You'll stay here?"

"Yessss, I promise." You weakly agree.

"Good! Besides, I don't know how safe it'll be for a man like you to go walking around the city. Not everyone will be as... happy to see you as I am." She stands up, leaving you in the mess she left you in, and heads for the door of her bedroom. "Oh, and I don't know when my roommate Alma will come back... but just stay quiet in here and she won't find you. She doesn't know about... me." Claire mimes having huge Titgirl-sized breasts. You nod in understanding and Claire leaves with her super-speed, the sound of the apartment's front door and whoosing air the only thing left behind.

Suddenly alone, your cum drying on your lap and on the sheets, you have some options.
