A demonstration with Professor Dove

"Yeah, I'd love that. Thanks, Professor." You're relieved to get some real help.

"Oh no, thank you..." She stands up and takes your hand. "And, it's Rebecca. I want you to feel comfortable with me." As she leads you around her desk to her office, you're mesmerized by her curvy ass. It's barely covered by her sweater dress. With each sway of her hips, it threatens to burst free.

You both enter the room. It's cozy. Without any windows, it's lit by a couple of standing lamps. The walls are lined with bookshelves. There's a cluttered desk against the far wall, and a black leather couch against the near one. She sits at the far end of the couch and pats the spot next to her. You oblige her and sit down. Her breast is squishing against your arm, but she doesn't pull away. In fact, you think she scooches closer.

"Do you know why this library is so quiet?", she asks.

"Magic?", you guess.

She chuckles. "Void magic. The enchantment placed on the library prevents any individual from hearing anything that they don't try to hear. For example, right above us, a Pegasus girl is getting railed by a Wyvern boy."

You can't help but listen to see if she's telling the truth. She is. The girl's moans are loud. Really loud! She's practically screaming. You wonder what position she's in? As you listen closer, you can hear the sound of her partner's hips clapping against her ass. The desk she's bent over slams against the wall rhythmically. The sound sends vibrations down the wall. Sitting on the couch, you can literally feel them fucking.

"See what I mean?" Rebecca snaps you out of your concentration. She runs her finger along your very obvious boner. "You can be as loud as you want, and nobody would know." She deftly fishes your cock out of your pants and begins stroking you. You lean your head back and enjoy the sensation. You realize you can't hear, or feel, the couple above you anymore. Out of curiosity, you listen to see if they're still there. Immediately you're bombarded with the din of their fucking. Yep, still there. You let the sound of them fade away as you focus your attention on the busty librarian beside you.

"As loud as I want, huh? Let's test that out." You guide her down in front of you. She kneels between your legs, still stroking you off. Rebecca maintains eye contact with you as she slowly, tantalizingly, lowers her mouth to your cock. She wraps her lips around your head, and licks it like a lollipop. Her tongue teases your glans as she continues jerking your shaft. Your tip is slick with her spit. Her fist spreads the lubrication along your length. Soon, your dick is a sopping mess. One that Rebecca greedily continues to suck.

Suddenly, Rebecca stops her ministrations. Her mouth agape, she runs her tongue along the underside of your member. When she gets to the head, she lets her drool spill out on top of it. Then she hikes up her dress over her voluptuous tits. Free at last, they spill out over your lap. Rebecca sandwiches them around your dick. They're silky smooth, pleasantly warm, and form snugly around your cock. You buck your hips in anticipation. "P-please..," you whimper. She smiles kindly, and begins stroking your cock with her tits. It feels sublime. Her tits fit you like a glove, hitting all the right spots. Steadily, she begins to pick up the pace. Her breasts are drenched in her drool. The sound of wet clapping fills the room as she slaps her jugs against your hips.

"Fuck, I'm gonna cum!", you tell her. She keeps up the pace diligently. "Fuck!" You shout as ropes of your cum fill her tits. A couple dollops hit her face. She pays them no mind and keeps tit fucking you, using your jizz as lube. You're gonna cum again. "Fuck, fuck, fuck!!!" More of your jizz fills her tits. You cum again and again, howling louder and louder. Her tits are overflowing with your seed. She slams them one last time. Your dick pokes over the top and drenches her face and hair with your sticky load.

"Stay here, sweetie. I have to go take care of something real quick." Rebecca does her best to wipe your cum from her face. Her hair is still a mess though. She stands up and pulls her dress back down over her cum soaked tits. The sweater appears unsoiled on the outside. Mostly presentable, she struts outside and greets another student.

Left to your own devices, you take a minute to process what just happened. If every trip to the library goes like this, you're going to spend a lot of time here. With nothing better to do, you put away your dick and crack open one of the books on the void element. Milling over the first few chapters, you think you can grasp the basis of the void element. It is a negation of elements, senses, and even concepts..or so you think. It's all very vague. You decide to open another book on practical applications. You flit around the pages aimlessly. You see applications to nullify or even counter spells. There's a section on ways to prevent detection. Towards the end of the book, you even see a spell to stop time. That one comes with several disclaimers though, and it looks a little too complex for you anyway.

You resolve to find something you could try right now. Flipping through, you find a spell to become invisible. You read the section and do your best to replicate the effect. The first attempt goes poorly, rendering you a pitch black silhouette. The second goes a little better; but looking at yourself, you realize that you're functionally a mirror. You undo the enchantment and reread the book. This is harder than you thought. You close your eyes, take a deep breath, and give it another go. When you open your eyes, you see that it worked! Waving your hands in front of your face, you can't see them at all! You feel a sense of accomplishment and release a shout of joy.

Just then, Rebecca passes in front of your field of view. "Well done, sweetie.." You undo the effect as she straddles you. "You've been such a good boy.."

"How long have you been watching me?"

"Long enough." She pulls your member out of your pants and rubs her sex along it as she speaks. "I wanted to see what you could do. And you were so focused on your task that I didn't want to interrupt you." You quickly get hard again. "We were in the middle of a demonstration.." The busty librarian lines your cock up with her pussy. She's soaking wet. You feel the heat of her sex. "Let's see if anyone can hear me squeal like a little whore for you." With that, she impales herself on your pole. "Ohhhh fuuuck!" She bounces on your cock, moaning lewdly as she does.

Her tits, still constrained by her sweater dress, jiggle as she rides you. Rebecca notices you staring. "You want these, sweetie?" With practiced skill, she pulls her dress off an tosses it on the couch. Free at last, her jugs clap wildly as she humps your cock. You greedily knead them. Her soft flesh fills your hands. You pull them around your face and let them smother you. You're trapped in her massive flopping jugs. Aggressively, you fill her boobs with kisses. Finding a nipple, you begin to suck on it. Rebecca's boucing body tries to tug it away from you, but you keep sucking on it. She's still moaning like a whore, but you think she's moaning a little louder.

Encouraged, you release the nipple and suck on the other one. This time, you grab her hips and slam her down on your cock. Mercilessly, you pick up the pace. Her moans ring out louder as you brutally fuck her. Her tit soon frees itself from your mouth. They flap unceremoniously, clapping all the while. You feel yourself about to cum, but give her no warning. You fill her womb with your seed, only to pick up the pace and fuck her harder. She screams in pleasure as, one nut at a time, you fuck her faster and harder. With one last nut, you impale her on your cock. Her lewd moan rings out in the otherwise silent room.

Fucked senseless, it takes her awhile to move. Though, you definitely feel her pussy contracting around your cock. Wordlessly, she tries to stand up and slumps herself down next to you. Her pussy is gushing with your cum. Your lap is faring no better. It's soaked with both of your juices.

Rebecca hands you the book on practical applications of the void element. "There should be a spell to clean up." You find it, it's one of the first ones listed. You perform the spell and successfully clean your clothes. Turning to Rebecca, the process takes a bit longer. Not just her clothes but her face, tits hair, and cunt are covered with your cum. Nonethess, you have no issues unsoiling her.

Satisfied, she gives you an affectionate kiss on the cheek. "I hope you'll come back soon.." You assure her that you will. In fact, you intend to spend a lot of time here. For now, though, you have somewhere to be.
