I get fucked

I opened my mouth to say something but all that came out was a loud moan as I kept repeating the words "Oh fuck" over and over. "Oh my god you are a little slut aren't you," My girlfriend said with a laugh. "You're my little slut now aren't you?" She asked leaned close as she slowed down until she was barely moving in and out of me. I just whimpered trying to ride her cock but she held me in place. "Ah Ah that cock is for good sluts, so are you are a good slut," She asked. I tried nodding but she twisted my nipple before I finally broke and said "Yes I'm a good slut". She started moving faster and asked, "So is this what you want, my cock?" I tried saying yes but words were getting harder to form and what came out was almost incoherent. "Say it" She commanded and for a moment I considered resisting until she pushed deep inside me moving her cock to the hilt causing me to break. "Yes please, I'm your slut your cock sleeve anything just please don't stop fucking me". She leaned down and kissed deeply and said "That's a good slut, or maybe you are just a cock sleeve" her words just made me more ashamed and hornier at the same time. She slowly sped up again fucking me faster and faster and harder and harder.

I could feel every inch of her cock as it slid in and out of me completely filling me. No matter how I struggled I couldn't move and my girlfriend didn't even notice my week struggles. I didn't stop though, because I soon realized being dominated turned me on. My body had been feeling like it was building to something for a while but suddenly I hit an orgasm so massive I almost blacked out. It was a thousand more times intense than I had ever felt as a guy and I could feel my body going limp.

Suddenly the throbbing inside me got faster and faster and my girlfriend got a crazed look on her face. "Ready to be a mommy?" She yelled almost frantic as she fucked me. For a moment she started fucking me like a wild animal and then with one last shuddering push she pushed as deep as possible and her cock exploded inside me. I had cum inside a lot of girls, I knew roughly how much cum was supposed to come out. What I got instead was a torrent of hot cum filling my core in fire causing my belly to expand as it kept going and going. I hit another smaller orgasm as the sensation of cum totally filling my body and spilling out of me consumed my mind.

When she was finally done my girlfriend fell on top of me before sliding down to my side never letting go of my body. She pulled me close with a satisfied sound as we both just lay there sweaty and out of our minds.
