That night Mackenzie and I texted back and forth. Mainly about her coming over and tutoring me more, I ignored every sexual thing she said. Good thing we were texting because she was turning me on. At first, I wanted to stick to my plan of not doing anything, being friends, and acting normal with each other. Yet, it just won't work with us. Either I'm trying to get her and she's not feeling it, or she's trying to get me and I'm not feeling it. I don't know what's wrong with us, but now I'm ready to be on the same page, we just have to work at it.

I made sure I gave Betty the day off so we could be alone. I wasn't planning for anything to happen, but in case something did, I wouldn't want someone messing it up for us. In no time, I heard the doorbell ringing. Walking as fast as I could, I hurriedly opened the front door for her.

"Hey Ryan."

"Hey." I replied. Like yesterday, I led her to the office.

She wasn't wearing short shorts and a half shirt like yesterday, but she still looked sexy. Mackenzie wore a short dress, like a regular dress that girls wear with sandals and sneaks. I really don't know how to describe it, I think it's called a tee shirt dress thingy...maybe. Truthfully I didn't know what it was called and really didn't care to learn, I just really cared about what was under it.

Reaching the office door, I opened it for her and let her walk in first. This time, I didn't stare at her butt. We sat down and relaxed before starting the work. After 5 minutes of sitting, Mackenzie was ready to start.

"Did you finish the problem I needed you to?"

"Yeah, but I don't know if it's right."

"Pull it out and let me see."

I nodded my head as I searched my bag for the worksheet. Finding it, I pulled it out quickly and shoved it into her hand. Wasting no time, she moved her seat forward and checked over my answer. While waiting, I watched her work out the problem. We've been working together so long, I've learned how she looks when she's struggling with a problem. She keeps licking her lips, scooted closer to the desk, and running her hand through her hair. Mackenzie was doing simple things, nothing out of the ordinary, but to me, when she did anything it was magical. The way she moved, the way she talked, everything is magical about her.

"Is it right?" I asked.

"Almost, you missed one step."

"Shit! I'm so fucking tired of this crap, I'm working super fucking hard and can't do shit right."

"Don't say that Ryan, you're trying your best."

"My best isn't good enough obviously!"

"Ryan! You're doing the best you can do and your working hard. You're doing just fine, we all struggle in something."

"I struggle with everything! I have to work super hard for every A I have, why can't it be easy?" I could feel myself ready to explode. I don't know why, but sometimes I just get so mad, so angry at everything. I try not to, but it's hard to stay calm about every single thing in life.

"Ryan, just calm down and take a deep breath."

"No." I wanted to calm down but I couldn't, it's like I cann't control myself.

Mackenzie stood from her seat and stood in front of me. Moving my arms and book bag, she smoothly sat on my lap. Her legs on either side of me, she slowly wrapped her arms around my neck, and placed her forehead on mine.

"Please calm down and breath."

"I'm trying Mackenzie, I just can't. I can't just calm down and breath, that shit doesn't fucking work."

She looked at me with our foreheads still touching and took a deep breath. We stared into each other's eyes for a few moments before I could feel her lower half grinding into mine.

"Will this make you feel better?" Kenzie started off slow, moving her hips in a circular motion.

"No." I replied with a hard glare.

She continued grinding against me, going harder and faster. Acting as if I didn't just give her any look at all. A soft moan escapes her lips before she lifted herself from my lap. Without asking or even giving me a look, she went to unbuckle my jeans, I grabbed her hands before she could do anything else.

"What are you doing?" I asked in a hard tone. Though she looked sexy, she was pissing me off trying to please herself.

"Trying to make Daddy feel better." She replied with an innocent tone. I looked at her confused and slightly dazed, I didn't understand what was going on.

"Oh, I-I.."

"Don't you want me to make you feel better?"

"Ye-Yeah...I gue-"

"Ok, then move your hands."

She swatted my hands away, and continued to unbuckle my jeans. I couldn't believe what was happening, it's like something came over her and she was sex needy. Kenzie pulled my pants down as far as she could without my help, eventually I stood and took them off completely. Sitting back down, I felt the cold air hit my naked lower half and all of a sudden felt silly for stripping down.

"I should put my pants back on." I said, reaching for them. Mackenzie quickly kicked them to the side.

"No, don't put them back on. I'm going to undress for you."

She pulled the dress over her head, and under her dress she was completely pantyless. Her kitty was shaved without a strand of hair, looking at her naked lower half I felt my dick jump for joy. It twitched the more and more I looked at her. Next, she slid off her bra, her boobs popping out and jiggling slightly.

"I don't know if we should do this."

"What? You don't want to fuck me?"

"It's not that, I want to fuck you."

"Then what is it? You're scared?"

"No, I'm not scared."

"You're acting like it, probably don't have any stroke."

"Now, don't go talking shit knowing that you can't take the dick."

"I can take the dick, you can't take the pussy."

"Don't get yourself in something you can't get out of. Is this what you want?"

"Yes, I want this. I want you to fuck me, NOW."

"Ok." I responded calmly as I took off my shirt.

I stood from the chair and told her to get on all fours, with her ass in the air. I got on my knees and positioned myself behind her, opening her legs slightly. I positioned my dick at her entrance.

"This is what you want right?"

"Yes nigga! I want you to fuck me hard!"

"Okay."

Right when she turned her head forward, I shoved my hard penis into her roughly. There was a loud scream that came from her lips. I let her adjust to my size for a second before stroking.

"You want it hard right?"

"Yes.." She moaned.

I gripped her hips tightly and pulled out, stopping at my tip and shoving my length into her again. Without warning, I started stroking hard and fast. I went in and out of her repeatedly, the smacking of our skin getting louder and louder. I slowed down so I could get on my feet, once on my feet, I grabbed a handful of her hair and yanked her head back. Holding her hip and a hand full of her hair, I slammed into her roughly, her wetness making it easier for me to move in and out of her. I could feel her tightening around my shaft, at which I slowed down.

"Stop squeezing me."

"I'm sorry Daddy, I'm about to cum."

"You can't cum yet, so stop squeezing." I pulled my full length out of her and waited for her to calm down.

"Can you put it back in? Please?" I smacked her ass cheeks hardly.

"What's my name?"

"Daddy." She responded lowly. I smacked her ass cheeks again.

"I couldn't hear you."

"Daddy! Please fuck me!"

I flipped her over and laid her on her back. Spreading her legs as far as they could go I pushed my manhood into her completely. Laying on top of her and holding myself up with my hands, I stroked her hard and deep.

"Ahhhhh!" She moaned as I slammed into her tight pussy.

"You like that baby?!"

"Yass Daddy! Ahhhhhh!"

"You wanna cum?"

"Yass! Please can I cum?!"

"Yeah baby, cum for Daddy."

I slowed my speed to grab her hips. Gripping them tightly, I stabled myself so I could fuck her harder. I stroked in and out of her, making sure I rubbed her g-spot in the process to make her cum. Looking down, I could see her wetness was all over me, I let go of the right side of her hip, and started rubbing her swollen clit in a circular motion. I gave her a few more deep strokes before I could feel her squeezing around my dick.

"I'm about to cum!" She screamed, with her eyes closed shut. With her moaning, her tight pussy, and her wetness, I could feel myself getting close.

"Fuck." I mumbled, feeling the warm sensation.

"Ahhhh! Right there Daddy!" I slammed into her even harder, my balls smacking into her ass

"Shit!" I hissed.

"Ahhhhhhh! Fuck me!"

"Come on baby! Cum!" As much as I enjoyed being inside her and making her moan, I knew I was reaching my end. I didn't want to orgasm before she did.

"I'm cumming! Ahhhhhh!"

Her pussy squeezed around me tightly, I continued slamming into her hard. I soon felt the familiar warming sensation and knew I was about to cum next.

"Fuck!" I hissed again as I quickened my speed.

"Cum Daddy!" Hearing her call me 'Daddy' one more time caused me to explode inside of her unexpectedly. I quickly pulled out, and released rope after rope of white cum all over her stomach.

"Shit." I said, even though the long ropes of cum were finished, I continued to ooze out more cum. My hand wrapped around my member as I stroked the few last drops out.

I knew I had some of Mackenzie's wetness on me, but I still felt a big puddle of warmth on my stomach. I blinked quickly and looked around the room, everything felt weird.......

It was pitch black, looking around I was under the cover in my bedroom. My forehead and body was drenched in sweat, and looking down I saw the puddle of warmth I felt on my stomach. It was my own spunk, I came all over myself. Slamming my fist against the bed I realized it was all a dream. I want it bad, and I ain't ever been obsessed before.
