Bum Sex 101

"Do I have to sir?" your girlfriend complains "Can't you pick on someone else. I really don't want to be involved in any demonstration of.....that!"

Her resistance is all part of the dance, you realise by now. It's inevitable failure not only highlights your dominance over Ria but also how determined you are to treat her as your sex toy - both of which she definitely finds hot when she is fantasising. You don't need to feel any guilt for giving her what she wants. Instead, you lean into it.

"Stop backchatting me and get up here now, Lewis" you demand "For the rest of this lesson you should consider yourself to be nothing more than a demonstration model for the rest of the class. You will not say a word. You will not roll your eyes at me. You will do everything you are told immediately and without question. Do I make myself clear?"

Ria glares at you somewhat theatrically, pushes her chair back aggressively to make an obnoxiously loud scraping sound and stomps angrily to the front of the room.

You wonder who her classmates are based on in this dream. Real people she went to college with? It is certainly an interesting new element for her to bring into a fantasy. She's never desired to be humiliated and sexually degraded in public until now, and in front of a large group of her peers, no less. Has that always been part of her sexual psyche or did she enjoy the other fantasies so much that she is starting to up the ante now? You will have to be careful that you don't end up turning your beautiful girlfriend into some kind of deviant. For now though, you decide to test just how much she enjoys the public element of this.

"Can anyone tell me why Miss Lewis makes such an ideal candidate for an anal sex demonstration?"

A few hands go up and you picked an eager looking male in the front row,

"Because she's fit!"

There is a ripple of laughter around the room at the inappropriate bluntness of the response.

"What do you mean by fit? That she's healthy? That she exercises a lot and eats well? Have you performed a medical examination on Miss Lewis to determine her level of fitness?"

Wow, you have the whole sarcastic teacher schtick down a little too well.

"It means she is conventionally pretty with soft symmetrical features and has a body that shows many outward indicators of physical health and relative youth. "

You turn to see that some dorky girl in an ugly yellow cardigan and cheap glasses, with her hair pulled back almost clinically into a bun, has decided to just call out an answer without being asked. Her voice sounded strangely familiar though.

Holy shit, is that Dani?

It is! So these are real people Ria went to college with then? You figure Dani just wasn't as smoking hot back in her academic days. Though, now you look at her properly for a moment, she was actually pretty cute. You decide it might be fun to get her involved too.

"That's a very good answer Danielle. Why don't you come to the front of the class as well?"

"If you were planning on asking me to be a second demonstration mode for this lesson I would seriously reconsider it" she warns you.

Yep. This is definitely Dani.

"No, Miss Lewis is our only demonstration model. I just need someone else to assist me."

Danielle nods in acceptance of that and walks to the front of the class as you continue to address them.

"You might be wondering why Miss Lewis's physical attractiveness makes her such an optimum candidate for anal sex. The simple reason is that such an act is carried out purely for carnal pleasure. It has nothing to do with love nor procreation. Can I ask, by a show of hands, who here has ever had a sexual fantasy about Miss Lewis?"

Many hands go up, mostly male but also some female - including Dani's. So what does that mean? That Dani is bi? That Ria thinks she is? Or would just like her to be for the benefit of this fantasy? You really can't be sure.

"Excellent. You see, Miss Lewis? Regardless of your complaints, your peers seem to agree with me that you are the perfect choice for this. Now, go and stand facing the wall so we can get a good clear view of you from behind.

Ria pouts but grudgingly complies. Since you can't see your girlfriend's face now to judge, you can only hope she is will enjoy the idea you have come up with as much as you are going to.

"Now obviously, it would be entirely inappropriate for a tutor to strip a student" you begin "But I see no issue with another student doing it. Miss...."

Fuck, what is Danielle's surname?

"Danielle. Could you please remove Miss Lewis' skirt and panties."

"...With your teeth!" you want to add, but since Dani seems to be acting a lot like, well, Dani in Ria's mind, you decide she would probably just yell at you and restrain yourself.

"Of course!"

Dani walks over to her friend and pulls at her skirt, which in this dream just seems to float right off.

Even before she got conventionally hot there was something very sexy about Dani. She is so confident and sure of herself without needing to be smug or cocky about it. Maybe it's because she possesses the kind of qualities you would like to have but don't that you find her so alluring, even when she is dressed like a total nerd.

Before long, Ria is stripped and ready for the practical part of the demonstration.

"Okay class, settle down. It's just a bum! Now, obviously, it would break just about every college rule if we were to have someone penetrate Miss Lewis' anus with an actual penis so, for the purposes of this demonstration, we are going to use a replica dildo to simulate one. Danielle, would you like to do the honours?"

"Certainly, sir"

"Wonderful. And I'd love it if you'd talk dirty to her while you're at it."

"You'd love it?" Dani folds her arms and raises an eyebrow at you "Is me talking dirty strictly necessary here?"

Fuck. That just slipped out. You've got to get back into character. Though you do really want to hear Dani talking dirty as well.

"I just think it would add to the realism and highlight that the act is primarily driven by pure lust" you tell her "And I'll give you extra credit for it."

"Okay" she shrugs.

Hmm, is this Ria's fantasy or yours now?

"Okay, you dirty little slut" Dani begins in that neat and deliberate manner she always speaks in "bend over so you can get what's coming to you!"

You watch in wide eyed amazement as the scene you have set up begins to play out. You also remind yourself it is literally impossible for anything to happen in Ria's dreams that she is not okay with. You do seem to have strayed quite some way from what was most likely her original vision for this one, though.

"That's it! You like that don't you who little whore?" Danielle enquires of her friend "Would you like me to push it in further? Shall we see just how far it can go?"

Ria is, thankfully, now moaning with pleasure.

----

You wake up back in the real world. Your partner is cuddled up next to you, roughly half asleep. You stroke her hair and she opens her eyes. You really hope you didn't go too far in last night's fantasy. There was way more improvisation than you had intended after Dani turned up.

Ria smiles and kisses you on the shoulder, which is instantly reassuring.

"Sweet dreams?" you ask mischievously.

"I can't really remember" she lies.

"So are you still up for some sexy role play today then?"

"Yeah"

"Are you sure? I don't want you to feel pressured to do it if you don't want to."

"Since when have you ever known me to do stuff I don't want to?" Ria is absolutely right about that and looks almost annoyed at the suggestion "I want to do it because you're my boyfriend and I love you, so stop checking with me okay? I know you mean well but it gets on my tits."

Wait a second, did she just slip in a declaration of love for you somewhere in that otherwise somewhat angry outburst? Dani was right, Ria really does like to downplay her emotions.

"Great, that's awesome. I won't ask you again, I promise."

"I was thinking though. I don't mind being the slutty office slave at some point, but it might remind me a bit too much of work at the weekend. Maybe we can do the schoolgirl one today?"

Damn, she likes that scenario as much as you, it seems.

"Definitely. You look so fucking hot in a schoolgirl outfit."

"What? How the fuck would you know?"

Shit. You can't let your girlfriend realise you can invade her sexual fantasies at will.

"I just meant you look hot whatever you wear. And I've got to admit, I have imagined you dressed as a schoolgirl more than once."

"Filthy fucker!"

She smiles approvingly and hits you lightly with a pillow.

"Oh, and I did have one other thing I was thinking about, for when I get dressed up later on."

"Yes...." you probe eagerly.

"I don't mind trying the bum stuff. You know, since you seemed really into the idea. But I've never let anyone do it to me before so if it hurts you'll have to stop immediately, okay?"

Oh fuck. This is amazing! Not only have you turned your office crush into your loving girlfriend, but you are exploring and expanding her sexual boundaries not just during your waking life but even while you are asleep! Ironically under the circumstances, you are slowly turning Ria into the perfect girl of your dreams.

So why can't you stop thinking about Dani?
