I waited, heart pounding in my chest as I felt the head of his cock press against my entrance. Heat radiated off him like a furnace, making every inch of skin tingle and burn with desire. Slowly, he pushed inside me, filling me up with hard, hot length. I moaned around his neck, arching into the sensation as he continued to thrust deeper, claiming my body for his own.
"Oh fuck," he groaned, "you're so tight... so warm..."
Your so tight sis and warm
I wrapped my legs around his waist, pulling him closer as he continued to thrust into me. My nails dug into his shoulders, leaving tiny half-moons of red in their wake. It hurt so good, this feeling of being taken by my own brother. There was no going back now; we were bound together by our desire for each other.
"Oh god," he groaned, "I'm close..." His hips bucked wildly as he came inside me, filling me with hot spurts of his release.
