When I first started my current job I was very outgoing to be sure that I was seen as. a hard worker. My boss(current GF) noticed and would give me difficult tasks knowing Id get them done and would praise me for it, which I loved. She is very short(probably under 5ft) compared to me(5ft10). She has shorter blonde hair and a curvy milf body(big ass/hips, and rack🤤). She had one day asked me to clean out an old storage office. I cleaned it within a couple hours and she thought it was going to take my whole shift. She told me happily it was going to be her new office and to put her things in there while she was going out on an errand. I smiled and told her "Anything for you!" She paused for a moment looking at me smiling and continuously adjusted her face as if she was having a hard time deciding what to say before she blushed and turned away saying "okay thanks!" I felt so good that I rushed all of her stuff over and got her computer all set up before she got back. I went to lunch and that's when I heard her page me to her office. My heart sank as I thought I had done something wrong. I got up to her office and she told me she wanted to tell me thank you and that she appreciates that I do whatever she asks. I told her that it makes me happy that she appreciates my hard work and that's why I am happy to do it for her. That's when she told me "Okay then, please lock the door so no one disturbs us" I got nervous that I had done something wrong since she sounded so serious. I turned around and she had gotten out of her chair and approached me. She touched my hair softly and asked me if I would do anything she asked like I said before. I nervously nodded as I got really turned on. She told me to unbutton her shirt, so I did. She told me to take off all of my clothes, so I did. As I took off my underwear her eyes stayed fixed on my hard cock for a long moment as if she wasn't sure of what to say next. She looked up to me and strictly said "Do As I Tell You" I nodded and she grabbed my cock and strokes it a few times before grabbing it hard and pulled on it as she told me to follow her to the desk, the whole time keeping her hand gripped tight. She told me to unzip her skirt. After it fell off her she turned around and and told me to put her on the desk and take off her underwear. I did so and was getting so eager to fuck her. As I pulled her underwear down she grabbed my hair and pushed me down to my knees and pulled my head between her legs. She didn't need to tell. me what to do at this point😏 She had both hands on my head telling me what to stop doing and what to keep doing for a few minutes until she came with my head being squeezed between her legs. She took a minute before sliding off the desk and pushing my chest with one hand until I knew she wanted me going backwards. I felt her chair behind me as she looked at me sternly and said "SIT" I sat down and she gave me a big grin saying "Good boy" as she removed her bra exposing her big beautiful nipples. Staring at them she asked if I liked them, to which I replied "I LOVE THEM" She walked forward then said "Well here" and pressed them into my face. I couldn't help but reach my hands around to grab her big ass, but she pulled back and gave me another stern look, saying "You didn't ask" I apologized. She leaned in and told me "You will do exactly what I say" I nervously nodded as she pointed over to the drawer and told me to open it and grab a condom. I quickly got up to get it as she smacked my ass. I grabbed the condom and turned to her. There was a pause and she praised me for not putting it on without her concent, then told me to put it on. I rolled the condom on and she told me to take the arms off her chair. After I did so she grabbed my shoulders and sat me down. She was breathing heavily as she told me aggressively almost growling "LOWER THE CHAIR" As soon as the chair slid down she walked over me with both legs still on the ground. She grabbed my cock and played with it on her clit for a bit before she lifted one leg and slid me inside her. She had seemed to lose control of herself as she grabbed my shoulders and viciously started jumping and grinding on me. I was sure to stay still until she told me to grab her ass, to which I was happy to do so. She started to seem frustrated for a minute before she got off and told me to pull off the condom. I did so as fast as I could, and as soon as I did she was immediately back on top. This time she was being loud and laid against my chest gripping my hair in her hands. She she got lower than she had before and started tapping my tip against her cervix. I started shaking as I could feel myself getting ready to cum. She turned my head to face her and said "You feel that? I want you to do what I say exactly. Don't cum unless I say so. Now you need to start fucking me, and hit this same spot!" I nodded and she slowed down as my hips started thrusting into her. She slowly tilted her head back with her eyes closed and boobs bouncing with every thrust I gave her. She told me "Go a little slower and push hard into me, every time" I did, and about half a minute in I could feel her pussy starting to clench my cock. I started building up and was getting ready to cum. My cock started throbbing as she looked down at me and growled "GET READY TO CUM" I nodded as she leaned back her head again and started thrusting back into me at the same time, hitting my cock against the back of her insides. I couldn't hold it in any longer as she let out a long groan and her pussy clenched down hard. She yelled"DONT MOVE!!" I stayed flexed in the air and I could feel myself about to pulse my first shot of cum. She put her hands down and around my ass as she pulled herself and I together really hard, pressing my tip so hard against her cervix to where I could feel my tip slightly penetrate deeper inside her. With a second in between each word she yelped "CUM! CUM! CUM!!!" I squeezed as hard as she was squeezing me, shooting throbbing load after load inside her. The pressure around my tip filled with gooey wetness building up and pushing in her deepest parts. She sat down on me and made me collapse in the chair. She stroked my hair leaning over my shoulder saying "THATS A GOOOOOOD BOOOY❤️" she layed on me for a few minutes before getting up and telling me to get dressed. She sent me home early saying that I'd done enough work for today. A few days went by until she said or did anything else. (This really got to me) - She called me up to her office once again and said, "Wow, I really thought that maybe you didn't cum. I just had your swimmers come out of me last night while in bed!" I looked at her nervously and blushing without saying a word. She smiled and said, "I thought it felt like you cum alot, and now I know you can😉 looks like I am deciding to keep you❤️" She hands me a note with her address on it. "Be at my place tonight so I can get a refill yeah?" and the rest is history🤤
