This is a short collaborative story between myself and YuriLemon with hopes of doing more complete ones in the future. In this story we take turns with me beginning the story. Please be aware that POV changes back with each line. Names have been substituted with usernames.
You let me know when he's asleep through text. Then because you left the doors unlocked I slip in and pull out my long thick meaty cock that I know you've been fantasizing about all day. I stand over you in the dark room and you sense my presence. You cuddle up next to him but leave your ass exposed out of the covers, right at the edge of the bed, and I slowly, quietly push myself inside of you. While you snuggle your top half close to him I crave your pussy more and I start pumping you harder to the point where you begin to moan so I reach under the covers and grab your big tit in my hand pinching your nipple til your silent. When he suddenly adjusts, I stop, standing over you both, my cock still inside of you. When he settles I slowly pull out and you adjust yourself so that your head is now positioned near the edge of the bed. That's where you start sucking my pussy-soaked cock with your mouth while I slowly and quietly uncover you exposing your completely naked body. But I don't stop there… that's when I slowly crawl into bed on top of you….
…And you grab my legs and place them on your shoulders. My husband mumbles something in his sleep and we both pause, but your cock is throbbing and you can't wait. You use your hand to guide your cock back to my pussy, and you start to slowly rub it up and down my clit. My heart is pounding in my chest, part from fear that he'll wake up but mostly from anticipation. I can't stop the whimper from escaping my lips, I need you to enter me again but you're taking your time.
Your hands reach up and cup my breasts, and you run your thumbs over my nipples. I reach down and wrap my hand around your shaft that is pressing against my pussy lips, feeling how hard you are. I rub the tip of your penis and feel the wetness from earlier. You pinch both of my nipples and you allow me to finally steady your cock at my entrance. You can feel my wetness coat the head of your cock again . Then you grab me by my hips and pull me towards you. A moan escapes my lips as I can feel your thick cock enter me again and I whisper your name. You start slow, but it feels too good and I'm so wet that you can't control yourself. The bed shakes to each of your thrusts, your hands still grip my hips as you pound your thick cock into my pussy. My husband stirs, the thought of him waking up makes me whisper your name in warning, "Yourelease, he's.." You silence me by…
… wrapping my big hand around your little neck and squeezing it tight so that no air can escape. The bed is shaking and my thrusts have only increased in rhythm and force. I'm pushing the full length of my cock into the depths of your tight wet married cunt with each thrust. Your husband rubs his face and seems about to open his eyes but instead he only readjusts, snuggling a little closer to you causing me to slow my thrusts momentarily. His leg rubs against mine and his head comfortably pushes against your shoulder while I have to readjust the arm propping me up over his shoulder. I lean low as I bring the full force of my fucking back and while the need for air slowly begins to overtake your body intermingling with the intensifying pleasure of an orgasm I whisper into the husband-free ear:
"You're my little fucktoy, do you understand? You see that man on the other side of your shoulder? You may have married him but you will obey me." Your juices begin to flow at the fact that you literally have your husband unconscious on one side and me giving you orders on the other, "I own this pussy. Anytime he fucks my pussy you will report it to me. What he did, how much you liked it… when you wished it was me." My thrusts had become deep and slow now as if to drive home the orders. While your need for air reaches fever pitch and reality starts to mingle with the surreal, I release my grip only enough for a slight amount of built up carbon dioxide to be released and a slow stream of new air to be taken in but it's immediately interrupted by my order, "Answer me!" I growl into your ear.
"Yes Sir," you manage to escape out of the small airhole before I re-tighten well before your body was able to take in the oxygen it needs. You begin to squirm for the need for air rubbing against your husband as you do. Once again he begins to stir…
… and this time you completely ignore him. Instead of quieting down, you take your cock out of me and flip me over in one swift motion. Finally, I'm able to breathe fresh air but only for a moment, because you lift my hips up and forcefully press my face against the pillow. Pausing a moment to find my wet opening you roughly enter me and the wet sounds of your thick cock thrusting into me fills the room. You groan as your cock thrusts over and over again into my slick cunt. You are close, but you want to hear me beg for your hot cum to fill me in able to finish. "I want you," you say with each thrust, "to beg for it."
I squirm underneath you, I can feel my own release so close and I know your cum will take me over the edge. I lift my head from the pillow, the speed that you are pounding into me makes it hard to talk. "Yourelease, please, please," I moan, totally uncaring that my husband adjusts himself again, close to waking with all of the sound and movement we are making. "Sir, please, cum in me, fuck me harder and cum in me!"
My voice begging sends you over the edge, you want to fill the pussy that belongs to you with your cum. Your last thrusts are hard and fast before you finally grip my hips until they hurt and bury yourself to the base of your cock into me. Your throbbing cock pumps it's semen into me, into your pussy. My muscles clench, my pussy contracts around you as my orgasm racks my body.
"Good girl," you croon, and take your still hard cock out of me. Your cum slowly begins to drip out of me as I lay exhausted on the bed. You lay down next to me, putting yourself between me and my husband. "Remember," you command, "you are mine now."
