Suddenly he reached up and shoved me off him roughly. I gasped in surprise as I fell off his lap and plonked onto the mattress. Tristan rose to his knees, his massive cock sticking proudly out from him like a weapon. His eyes were filled with primal lust that was both arousing and terrifying.
He let out a horny growl and without a word, he grabbed my hips and flipped me over, pulling me onto my hands and knees. I knew what he was about to do.
“Tristan, no. That’s too far,” I said, though my protests were half-hearted at best. Foreplay was one thing, intercourse was too risky. No matter how horny I felt.
“Shut up, sis,” he replied. “Now I’m going to show you how good it feels to be dominated. You’re going to learn who owns you.”
He pushed his cock against my hole, threatening to enter me but not following through. Yet. He moved it around in a circular motion, stimulating and teasing me, spreading my juices. I remained frozen in place, fear and arousal paralyzing me.
“Beg for it,” he said, his voice bestial and commanding.
“What?” My cheeks were burning, and my breathing was heavy.
“If you really don’t want to do this then I won’t force you. But if you do want this, and I suspect you do, then beg for it,” he said.
I gulped, my eyes were wide. I wanted it, deep in my core I knew that. But he was my brother and it was wrong. If I gave in now there’d be no end. This could well be my one chance to end his blackmail for good. He was offering me the chance to refuse. And yet, my hormones had seized control of me. Rational thinking was a thing of the past. All I wanted was to give in to the throbbing ache in my vagina.
“Please Tristan,” I said, my voice a weak whisper. “Please, Tristan. Please fuck me.”
“Why?” he asked. His cock still hovering at my entrance.
“Because I want to feel your thick cock inside me,” I confessed.
“Are you a horny little slut who exists only to satisfy my urges?”
I hesitated and blushed. But I couldn’t deny it. “Yes.” I croaked.
Tristan let out a satisfied growl and without another word, he pushed himself into me. I gasped as his thick cock spread me open. He started to thrust and I felt pleasure and heat build inside me. He moved in and out of me faster and harder, like an animal in heat. I moved my hips with him, feeling the pleasure intensifying. He grabbed onto my hips and pulled me back, pushing himself deeper inside me. The sensations were too much for me and my breathing increased in tempo. I let out a loud moan of pleasure. I surrendered to my brother’s animalistic desires, feeling each and every thrust as he claimed me for his own. An unbearable wave of pleasure rushed over me as he rocked his hips against mine. I’d never felt so completely owned before, so completely and totally at his mercy. And I loved it. Every thrust sent shivers through my body, pushing me closer and closer to the edge of bliss.
“Oh, fuck yeah, your pussy is soaked!” Tristan said, panting as he pumped in and out of me.
All I could offer in reply was a breathy moan as I submitted fully to the pleasure he was inflicting on me. Still gripping my bucking hips, he drove in deeper, harder, and longer than before. His thrusts grew faster and deeper and his rampant cock filled me completely, sending shockwaves of bliss over my whole body. I let out a moan of pleasure-filled ecstasy that echoed through the room. My orgasm was building and building, and there was nothing I could do to stop it. I’d never felt anything like it before.
Tristan slapped my ass hard and with a loud roar of pleasure, he reached his climax, flooding me with his salty cum. I let out a sharp gasp, the pleasure of my orgasm overtaking me. I screamed out in pleasure as my orgasm rocked through my body, harder and longer than any I’d experienced before. I collapsed onto the bed, limp and completely spent. Tristan collapsed on top of me, his sweaty body stuck to my own. He let out a satisfied sigh.
I lay there afterward, my arms and legs trembling. I felt completely overwhelmed. I’d just had sex with my brother, something I’d never dreamed I’d do. And it had been ecstasy.
“Thanks, Erin,” Tristan said, his domineering attitude replaced by a softer tone. He pushed himself up and I could feel his now soft cock slide over my body. He leaned down and planted a tender kiss on my cheek before he hopped off the bed and walked into the bathroom, his dick swinging between his legs as he went.
I lay there for a while, the pleasure of my orgasm still coursing through my veins. I had just let my brother have complete control over me, and it had felt amazing. My desire for him had won the battle, but as I felt the warmth of his cum drip down my leg, I knew that this was only the beginning. We were both going to be addicted to this newfound pleasure and I wondered if I hadn’t made a mistake by begging him to continue.
