The gleam in your girlfriend's eyes doesn't fade in the slightest and she starts giggling. You're frightened and you turn to leave, but you she says, "Stay here," and you obey.
"Take off your panties," she orders. You obey.
"Wring them out, into your mouth."
Once again, you obey, tasting the saltiness of your own urine.
"Lap up what got on the floor."
The taste is now mixed with the sterile taste of the floor and it occurs to you that with your skirt, anyone behind you has a pretty good view. Your girlfriend is practically giddy with excitement.
"Go to my house and await further orders there."
You unquestioningly leave school and walk to your girlfriend's house. She didn't really tell you what to do there, but you find you can't leave, so you plop down on the couch and start watching TV. Then, your girlfriend's little brother comes down the stairs and finds you sitting there.
"Woah!" he exclaims. "Sis was telling the truth."
"Your sister told you about me?" you ask.
"Yup, and she said you're all mine for the day as long as I give you back in tact when she comes back."
"Why aren't you in school?"
"I had an off day today."
Your girlfriend's brother is in his early teens and the thought of being in the control of a boy that age frightens you, but there's not much you can do about it, or is there?
"I'll give you five dollars if you tell me to go home," you say.
"Just give me the five dollars."
You pull out five dollars from your mom's old purse and give it to him.
"See, that's not a very good deal for me."
Darn it.
"Now, give me the best blowjob you can."
You get on your knees and wrap your lips around his penis. You start sucking and bobbing, emulating girls you've seen give blowjobs. He cums. The taste isn't awful, but the thought of having another guy's cum in your mouth disgusts you.
"Swallow," he says, and you do. "Now, let's take a bath."
You follow him up the stairs to his bathtub. It's easily large enough to fit both of you. He fills it up and you both soak in the warm water. You have to admit, this is actually pretty pleasant. How could he ruin this.
"Masturbate for me. Moan my name and yell when you orgasm like a porn star."
You immediately stand up, sending one hand to your vagina and another to play with your breasts. You moan his name as you go and when you climax you yell, "Oh, I'm cumming!"
"Let me do anything I want to you."
He plays with your boobs and fingers you. You get out of the tub and have vaginal sex. Not that you have any active part of it. You just lay there and let him take you.
"I wish your boobs were a little bigger," he says.
"Well too ba--Holy crap!" you exclaim as your breasts grow two cup sizes.
A manic smile spreads across his face.
He spends the rest of the day toying with you. He pees on you, forces you to eat off the ground, kiss his feet, and be perpetually horny. Fortunately, it seems he can't control your thoughts, but your body responds to his every command. Fortunately, it seems he's satisfied with your body because he doesn't change anything else. Finally, the end of the school day comes and your girlfriend returns and demands you back.
"I think we should let her decide who she wants to be with," says her brother.
"Good idea," she says.
You pick...
