Gary had pushed me over the edge, and now he was keeping me there. He would not allow me to come down. He kept forcing wave upon wave of orgasmic spasms through my core despite my pleas to allow me to stop.
I was exhausted having endured the series of massive convulsions from my first multiple orgasm. My sides and abdomen hurt. But I could not stop cumming as my brother continued to stimulate me. I was forced to endure convulsion after convulsion as Gary sucked my clit while continuing to assault the inside of my womb with his fingers.
My clitoris was so swollen, I feared it my pop as he sucked on it harder and harder. It was engorged with blood and felt larger that I ever remembered before. It was so sensitive, the constant stimulation actually hurt a bit despite the fact that I continued to climax.
"Gary, enough. Please let me stop. I need to stop." I was pleading, as I tried to push his head from my pussy.
But before I could pry his mouth from my erect clitoris, I felt another wave of orgasmic pleasure crash across my belly, sending spasms of pleasure through my core. As soon as the next waves of the climax started, I stopped trying to push my brother's head away and held his head in place as I would grind my vagina into his face and jaw. I was grunting and groaning involuntary gibberish as I came.
"Oh shit! Oh my god! I can't stop...oh fuck,...please, ...oh god!..."
The screams of pleasure were incomprehensible as they escaped my throat. In fact, they noises I was making sounded more like groans and moans an animal might make than any form of communication from a young girl. Looking back, I wonder if a stranger hearing those sounds would have concluded that I was in the throes of ecstasy or I was in agony?
After the latest series of waves subsided, I was determined to break free. I had to stop or I was going to pass out. I simply could not continue to climax again and again. I was dizzy and lightheaded.
I mustered all my strength and pushed his head back, breaking the suction his lips and tongue had on my clit as I begged panted, "Please Gary, please. You need to let me stop. You need to let me down."
I lay there panting, sweat forming on my breasts, a little river of perspiration running between them, trickling down towards my navel.. My rock hard nipples continued to heave up and down as I struggled to catch my breath. I was dizzy and slightly disoriented.
"Oh my god...that was amazing!" I managed to say.
Gary looked at me and actually beamed with pride, smiling broadly. He was very pleased that his efforts had produced such a profound result. He owned his little sister at that moment. And quite honestly, after the events of the past two days, he would always own a part of me.
Very slowly, he removed his fingers from my vagina. I felt my entire uterus spasm at the sudden emptiness. My vagina throbbed and pulsed, it seemed to be trying to find something to grasp, to fill the sudden void inside of my womb.
I was still gaped open, my lubrication seeping out of me. My pussy felt empty and open, and very lonely.
I looked at my brother and saw his erect penis still straining towards the ceiling. He was ready to penetrate me with his penis. After the 'earth shattering' orgasm Gary just gave me, I felt that owed him that. I wanted him to penetrate me, to make love to me, to fuck me.
"Come here." I instructed as I laid back prepared to accept his massive boner. My head was still spinning from the multiple orgasms, and I felt a bit disoriented, but I knew I wanted to make love to Gary.
Gary crawled between my legs, his erection waving wildly in front of his as he approached me. He positioned himself with the head of his erect cock at the very opening of my vagina. As he leaned forward to kiss me, I could feel the head inching its way past the outer folds of my vulva. I was so wet, and so dilated that Gary's penis found the entrance to my vagina quickly. The saliva from Gary's mouth, coupled with the lubrication leaking from my arousal, allowed Gary to simply slide into me easily.
I noticed immediately that this entry felt very different from when Gary first entered me yesterday. There was no struggling to gain entry this time. He simply slid into me. Had he stretched me that much after being inside me just one time?
Then it struck me. It was not that my vagina was noticeably larger already; we forgot the condom! My brother's erection was inside me, unprotected. Oh shit! How could we have been so careless? So stupid?
"Oh my god, Gary, pull out!" I screeched. "You need to use a rubber."
Gary hesitated for a moment, processing what I just said. He stopped moving, but did not withdraw. Instead, he hovered over me with his hard erection pulsing inside me.
"Liz, I'll pull out before I cum, OK?" he argued. He clearly did not want to disengage at this moment.
Even in my irrational, highly aroused state, I knew this was a bad idea; I knew this was beyond stupid. Our entire world would end completely if I got pregnant.
"No, Gary. Please. You need to get the rubber now. Please." My voice cracked and quaked with fear. He was too large for me to 'for me to force him off me'. I was pinned under him, helpless and vulnerable. He continued to hesitate.
"Please Gary, please." I begged. "I will let you fuck me as much as you want, just please, use a rubber."
I started to cry. Tears suddenly ran down my cheeks. I feared the absolute worst. My mind raced to remember how long it had been since my last period. In my confused and emotional state, I could not remember exactly; but I knew it was a couple of weeks ago. I was very near the most fertile part of my cycle.
My brother saw the tears flowing from my eyes, and my breasts heaving as I sobbed; his penis still inside me.
"Liz, don't cry. I'll use a rubber. I'll go get it. Please stop crying." Gary slowly pulled out. His cock sprang skyward as he exited my womb.
Gary leaned forward, kissed me on the forehead, wiped the tears from my eyes. It was clear that the mood had suddenly changed. Gary looked a bit down trodden by my emotional outburst and tears.
In an effort to comfort me, he offered, "See, I did what you asked. Please stop crying. I'll be right back."
I lay there for several moments trying to gather my thoughts and control my emotions. This was a stark reminder that Gary and I were playing with fire. This was a reminder that I should not allow my brother to enter me; to mount me. I knew it, and he knew it. But I could not seem to control myself. I needed him inside me now. I needed my brother to make love to me, to touch me, and to fill my void, both figuratively and literally.
