Then I deep throated his whole rod. This was something I was never experienced with or wanted to do but I just had to have him inside me more and more. My head bobbled up and down on his thick cock that filled my mouth completely, and I gagged a bit, but relaxed my gag reflex and continued.
“Oh, fuck, I’m gonna cum,” he gasped. “Oh, God, I’m gonna cum again! Little stepsister, you’re such a good slut and such a naughty girl. He make me cum so fucking much.”
And then he did. He blasted a huge, hot, white load of semen into my mouth. Slurping it up, I let it fill my mouth, then opened it to show him. He reached in and got some of his white cream out of my mouth and started rubbing it on my breasts, pinching my nipples while his cum glistened on the tips of them.
“I couldn’t wait to see this big, juicy tits of yours,” he said. “And now my cum is all over them. Your stepbrother has marked you as his slut. You’re mine, always.”
“Good,” I said, smiling as his cum got stuck in my throat as I tried to talk.
I eagerly swallowed the delicious gooey mess, licking my lips afterwards, as some of the load dribbled down my face and breast.
Who was I now?
Who had I become?
My sexual awakening had unleashed some kind of beast.
I couldn’t get enough.
For the next three hours, we continued our sexual escapades. Again, he would plunge his cock inside me, and I would spread my legs for him as far as I could. The feeling of his big, hot cock stretching my walls was too amazing not to keep experiencing over and over.
I knew then that nothing else in the world could compare to having sex with my stepbrother. No other cock would be as good as his. I wanted it again and again.
We both kept cumming and we were each amazed at how often we could do it. I supposed it was because we were young, but it felt like we both had a lot of pent up sexual frustration.
We both just needed to explode, and our bodies must have been storing up these orgasms, just waiting for the right moment to release them all.
On the fourth time that we had sex, we took it to the next level. He had started to push his cock in from behind on my ass, then realized what he was doing and backed off.
“No,” I said. “Fuck me there, too. Fuck me everywhere.”
“You want your stepbrother’s cock in your ass?” he asked me. “You want my big cock to stretch open your tight little ass hole as far as it will go, and ravage it like it belongs to me?”
“Yes,” I told him. “My ass hole belongs to you as much as my pussy does. Ravage it. Fuck it hard, stepbrother.”
“What a good little slut,” he said, praising me by smacking his cock up against my asshole and hitting my ass cheeks with it. “You’ve already learned to let your big stepbrother do anything he wants to you. You even let him fuck your tiny little asshole.”
“No one else has ever done that,” I confessed.
“Your tiny little untouched asshole,” he said, “is going to be open so wide for me, for its very first time. My cock is going to stretch it bigger than it ever knew it could be stretched.”
I had never even thought about anal, but I wanted Phil to do it. He pushed in and I heard him strain from the effort. I put my face down in the couch and grimaced because it hurt as he stretched me wide open just as he had promised.
“It’s okay, little step sissy,” he said, as he held my ass cheeks and spread them wide apart so he could position his cock inside my ass hole better. “It will feel good soon. I promise. Just be a good little slut for your stepbrother and put up with the pain so that you can feel the pure joy of my big cock in your tiny little ass hole. Okay?”
“Okay, big bro, my big, hard, step bro,” I told him, gipping the pillow. “I’m ready.”
He reached around and started massaging my clit and it made my pussy so wet that I soon forgot about how much it hurt for his huge cock to be stretching open my little ass hole. With his cock halfway in my ass, he rubbed my clit, while his other hand massaged my ass cheek.
“There, there, step sissy,” he said. “That’s a good girl. That’s my good little slut. Just relax for your stepbrother and let him have your whole ass hole. I need the whole thing. I’m going further in because this is just a tease. I need to be cramming you tight in there, just like I did your pussy. Okay?”
