Adrien's POV

I glance around to make sure we are out of sight of the security cameras, knowing we are far enough away from the other library occupants before I pull Marinette to me.

"So, what exactly did you have in mind?"

"Oh, me?" She feins innocence, turning away from me to peruse the shelves. "I'm just trying to do some research for my physics professor. He gets pretty mad when my homework isn't done." She stretches in attempt to reach the top shelf before glancing over her shoulder coyly. "Can you help me, sir? I can't seem to reach, and I really need to master this subject."

I close my eyes and beg for mercy while simultaneously thanking every deity, including the ones we carry around with us, for giving me this woman. I walk up behind her, pressing my erection into her ass as I reach to get the book she wanted. I hold it in front of her as I subtly grind into her before I whisper in her ear.

"I don't think this is the subject he wants you to research. I think that one's down here." I slide my hand down the back of her body and lower myself to my knees, watching her tremble as I reach between her legs for a different book. She bends over to look, giving me a glance of her panties. Wait—wasn't she bare earlier?

"No, sir, I think that one's wrong, too." I nudge my nose against her covered crotch and hear her whimper.

"I think you're breaking uniform. Where did you find panties like these? Don't you know you should be bare for your professor?" I trace my hands up her legs, pushing her skirt up to grab the waistband of her underwear. "I need to thoroughly examine your project. How am I to do that if you're hiding it?" She giggles a little as I slowly pull them down.

"Sorry, sir. I remembered I had a spare pair in my bag, and my boyfriend told me he was the only one allowed to see." Having removed them, I turn her around and pull her down to the ground with me. I lay her on the ground, quickly looking around to make sure no one is remotely near us before I continue the roleplay.

"Your boyfriend will have to get over it. This project counts as your term grade." I push her skirt back up and spread her legs to see the beauty between them. My erection throbs as it becomes more and more exposed. I snatch up the discarded panties and shove them in my pocket for later.

"Am I passing, professor?" She pants, her face flushed with heat.

"I'll need to be a bit more thorough in my inspection." I lay down on my stomach as close as possible to look at my handiwork as I slip my finger through her folds and caress her inner walls. She lets out a moan.

"Oh, professor…" I chuckle darkly.

"You may want to keep it down. Marks will be deducted if you make too much noise. Anyone could find us." Her breathing quickens, and I feel her walls pulse around my digit. "Oh? Does the thought of someone finding you splayed out for me arouse you?" I rub against her G-Spot as I ask that question and watch as her hands fly up to cover her mouth. I withdraw and smack her bare pussy. "I asked you a question."

"Yes, sir."

"Good girl." I shift in discomfort, my erection pressing into the ground as I resume my "inspection". "I think I'm almost done, just one more thing to check."

"What's that, sir?"

I don't respond verbally, choosing to wrap my lips around her clit and suck hard while my fingers thrust in and out of her passage rapidly. My other hand reaches up to cover her mouth as she screams against it and thrashes under me in pleasure. Her hands are in my hair, yanking, and I groan, causing her to squirt into my mouth. I lap it up as she comes down from her high, slowing my thrusts to help her ride out the orgasm before I withdraw completely. I wipe the excess juices on my face and stick my fingers in my mouth to get another taste as she lays panting in front of me.

"A plus."

She laughs breathlessly in response and rolls her eyes.

"Extra credit for squirting."

"Adrien!" She squeals, embarrassed.

I pull some baby wipes from my pocket, having stowed them before we dove into the stacks. I help her clean up before I clean my face and hand her panties back to her.

"You were right." She looks at me questioningly. "You were definitely knocked up by your professor, not your model." She laughs before she looks down and sees my raging hard on.

"I don't know. I think I need to get your measurements now. Stand up, Mr. Agreste." I'm quick to follow her instructions, knowing only pleasure awaits.

"Now, I don't have my tape measure, so I'll just have to use my hands. Spread your legs a bit, please." I do so, nearly shaking with arousal. She walks her hands up the inside of my leg before announcing her assessment. "Inseam roughly 6 and a half hands. I'll have to get a bit more intimate for this measurement, Mr. Agreste, but I assure you, it's all professional," she winks as she unbuttons my jeans and pulls them down with my boxers before she grips my length, giving it a couple of strokes. I lean against the bookcase behind me, panting in need.

"Hmm… a little more than a hand around in girth." She lines up her palm with the base of my shaft. "About a hand and a quarter in length. Very impressive, Mr. Agreste. Unfortunately, that's all I can do with my hands, but I think my mouth could give a more thorough assessment. What do you think?" She glances at me with false innocence.

"I—" My voice cracks, and I clear my throat before continuing. "I think that sounds about right. I mean, we can't have inaccurate measurements, can we?"

"No, sir, I suppose not. Let me get right on that for you." She wraps her lips around the head, sucking solely there for a minute before beginning to bob her head. She swirls her tongue around the tip as she comes up, prodding my hole before hollowing her cheeks and bobbing again. My hands wind in her hair and I begin to thrust into her mouth. She meets my eyes and I groan, thrusting faster. Her hands come up to play with my balls and I topple over the edge, biting my lip to keep from screaming her name as I thrust my length down her throat. She gags as my seed fills her mouth but grips my ass to keep me from withdrawing as I continue filling her mouth. When I've finally finished, I pull out. She opens her mouth to show me my seed before she swallows, and I whimper at the sight.

"Jesus, Marinette. Are you trying to kill me?"

"Not at all, sir." I pull her up from her knees and press my lips to hers in a bruising kiss. She moans into my mouth, and I have to tear myself off of her before I lose control and take her. I grip her face in both hands as our foreheads press together, both of us panting for air.

"Okay, we need to actually go work on the project now before someone comes looking for us. Or before I lose control and actually fuck you in the stacks because this is not where I want it to happen, and I'm very close to doing it anyway." She gasps and blushes before pouting.

"I guess you're right. Fun's over?"

"Only until later, princess." She gives me an odd look. "What?"

"That's what Cat normally calls me, but he adds a purr to the beginning." I chuckle nervously.

"Must be because we hang out so much. Don't think too much into it." She shrugs and takes my hand.

"Okay. Let's go get to work. The sooner we get the project done, the more time we have to fool around later in the semester."

"Good point." We rush back to the table and start to outline what we want to do. We know we need a place to live, and a car. Both need to have enough space for our child. We also want the house to have an office for me and a sewing room for Marinette. We need to budget for a mortgage, car payment, home and car insurance, health insurance, and necessities for the baby. We also decided to make a budget for groceries and household items. For our event, we decided to plan our wedding. The bell rings as we finish our outline of what we need to do, and I am positive we are already miles ahead of all of the other teams.

As we pack up, I can't resist saying, "So… who do you think knocked up Alix?" Marinette bursts out laughing.

"Oh my god, did you see their faces when Mendeleev said that? It was priceless."

"My bets on Kim. I feel like Max would be too technical. But the real question is…" I wrap my arm around her waist and pull her to my side as we start to walk out. I lean down to whisper in her ear, "Was it me or Cat that put a kitten in you?" She blushes and squeaks.

"Adrien!"

"It's a fair question, baby. Who had you first?"

"I haven't decided yet," she mutters, pouting and looking away as I press a kiss to her blushing cheeks while I laugh.

"Relax, Mar. Neither of us are pressuring you." She presses a kiss to my jaw and leans into me more.

"I know… Do you think we can make it out without running into anyone?"

"Only one way to find out. And if we do run into anyone, we stick together. I can't do this without you." I look down at the ground, ashamed of how weak I've been. Marinette pulls my face to look at her.

"You don't have to do it without me. And it doesn't make you weak to need support. It's written all over your face that's what you think, but it isn't true. It takes strength to ask for help when you need it. I'll be with you every step of the way, just like you are with me." She presses a kiss to my lips, then grabs my hand and wraps my arm around her without letting go. "We can do this." We start walking towards the exit, growing closer to the sounds of students and unsure which ones we will come across.
