The news has warned us to stay in since the snow has caused accidents and blockage on the roads, I flick through the maths pages whilst sticking the pen into my mouth. Alexander was showering, I stare at the question in confusion and stand up with the book in my grasp as I walk towards the bathroom.

I push the door open and see Alexanders shadow behind the curtain. I notice his hearing aids settled on the counter of the sink.

"Alexander!" I push the curtain open; he wipes his eyes and looks down at me.

"I'm literally fucking naked Nova."

"I like this view." I smile at him before shoving the book into his face, he grabs the curtains of the shower and pulls it closed. I close the toilet seat before sitting down on it as I wait for him to finish, a couple of minutes later Alexander finally steps out. My eyes land onto the-whoa-fuck-he was absolutely huge.

He grabs the towel and dries himself before wrapping it around his waist, I wait for him to slip on his hearing aids. Once he does, I begin; "I need help!"

"Hence why there's something called the internet Nova." He brushes his teeth, looking at me through the reflection of the mirror.

"No, I want you to teach me. I learn better, and my exam is in one week!" Alexander spits out and rinses, he exits the bathroom and I follow after him into his bedroom. "Please..." I whisper.

He pulls of the towel, revealing his ass. I chew on the back of my pen as I stare at it, wow, his ass is-then he turns around and my eyes shoot up to his face. He slides on his Calvin Klein boxers on and walks to the bed, I slide on the other side as he picks up his book.

"Alexander..." He sighs and glances at me, he takes the book from my hand and reads the question.

"Okay, look here," I look down at what his finger rested on. "There is a function, called the Riemann zeta function, written in the image above." He points.

"Okay, I get it..."

"For each s, this function gives an infinite sum, which takes some basic calculus to approach for even the simplest values of s. For example, if s=2, then 𝜁(s) is the 1 + 1/4 + 1/9 + 1/16 +. Get it?" I glance down at the question once more and put the explanation he has given me into mind.

"So then-it adds up to exactly 𝜋²/6."

"Correct, When s is a complex number—one that looks like a+b𝑖, using the imaginary number 𝑖—finding 𝜁(s) gets tricky. So tricky, in fact, that it's become the ultimate math question."

I gasp, finally understanding the question as I snatch the book out of his hand and write everything down before I forget it. I can now finally shut the book and set it to the side, "you know how attractive you are when you explain maths to me."

Alexander raises a brow; my hands slide down his chest before diving under the covers. "Nova." He warns me, my hands slide over his underwear. "Nova what are you-" My lips were on his before he could finish speaking. I kissed him passionately, and his hand dropped. He didn't touch me at first.

His fingertips touched the back of my neck as his hand travelled up my spine. They moved up until they became entangled in the hair at the nape of my neck, at which point he grasped a handful of it in his hand, tugging on it and breaking the kiss. He raised his hot lips to meet mine, his eyes on fire, both of us breathing raggedly. He looked at my face and eyes, undoubtedly recognising how desperate I was for him.

Could you blame me? After the night he treated my body like a temple, I wanted to do nothing but the same for him. I removed his hand and straddled his legs, what made me so crazy and hungry for him? I guess it was the way he looks at me. "Nova-"

I yanked on them, but he didn't lift his hips to make things easier for me, which only fuelled my determination. I yanked on his joggers more till I saw his underwear, then peeled those down just enough to see his cock.

He jumped out, firm, long, and dark, veins running up his shaft. His tip was round and thick, like a bulb. He was enormous, and glancing at him left me stunned and intrigued. I shouldn't have expected anything less from this man.

My finger running across the tip of his cock to wipe the pre-cum away. I thought I felt his entire body shudder. I use my hands to push him back down before stroking it across his muscular abs as he is about to sit up.

Then I lowered my head and took half of his cock into my mouth. "Fuuuuckkk," he murmured, and the tightness within him increased. His hands formed fists. As I drew him deeper into my lips, his head dropped back, his face pointing to the ceiling. I have given a blowjob before, obviously during high school I decided to follow those hormonal feelings.

Alexander was quite vulnerable to me. I sucked his cock quicker, putting a hand around the base and lightly pumping it. My tongue swirled around his tip again, and I licked the saltiness away, causing a deep rumble in his chest.

His head slumped as he looked up. When his gaze locked on mine, it was ferocious. He noticed my head bob and how my tongue made his cock wetter. He stared as I stroked him with one hand, my lips wrapped around his thick, lovely tip.

His bottom lip was hooked between his teeth, and one of his hands came down to the back of my head. He pressed down, forcing me to take him deeper. I gagged as he pushed farther in, but I didn't turn away from him.

He enjoyed it, especially the noises I made with him in my throat. My tears welled up, and I drew my hand away, allowing him to take the lead. He lifted his hips up and lightly fucked my lips, his hands on either side of my head.

Each time his cock struck the back of my throat, I choked, but he would ease off, allowing me to catch my breath before going right back at it.

"Look at me Nova, whilst I fuck that pretty little mouth of yours." My pussy clenched at the sound of his voice. I remained staring at him, felt his thighs widen apart to better position himself. He was tough and big. I almost couldn't breathe, but I knew he was close and couldn't stop myself.

"Fuck I'm nearly there-Fuck Nova just like that."

He was about to blow up.

His entire body had stiffened up, his cock so hard it could break something. The salty liquid then shoots to the back of my throat. Alexander groans and presses my mouth into his dick, his head falls back, and he relaxes before releasing my hair as his cum drops out of my mouth.

I swallowed it without him asking me to, Alexander takes my arms and brings me to rest on top of him. He wipes something from the corner of my mouth before pressing his lips against mine, his hands travel down my shorts before sliding under to grab onto my ass.

I feel his cock harden against my thighs, I chuckle before he switches position, and I am underneath him.

He kisses down my neck, lifting my shirt to give his greedy eyes a glance of my breasts. Then my phone rings, distracting us both.

Alexander glares at my phone. I smile and gently shove him to the side before reaching out for my phone. I look down to see Jane calling, I have not called her since I moved here. I leave her a message saying I am busy, and I'll call her later tomorrow.

"Your fights tomorrow, Alexander," I whisper as I settle back own onto the bed.

"It is."

"And I hope you told them you have a guest coming."

"I didn't. Because you're not coming Nova."

"Why not?" I ask, raising a brow.

"Because I don't want you to come and see what I do. There are bad people there, and I don't need you dying on me."

"Okay, fine..."
