A Back Rub For Julia Ch. 05

... impossibly tight grip on my shaft, and cum gushed forth, soaking my thighs. I held her tight, and whispered to her. I told my sister how beautiful that she was, how happy that she was making me, and how much that I wanted and needed her. Her body was inhumanly tensed from head to toe. She was so tense that she trembled all over from the exertion. Her eyes were glassy, and her mouth was slack, and her face was blank. After what seemed like an eternity, she slumped limply against me, like a rag doll, shaking. When she could finally draw breath, it came in ragged gasps. I just continued to hold her tight, and gently kissed the sweat slicked slope of her neck. My cock throbbed inside her, filled with a burning need for release. I had withstood intense orgasms from two tight, teenaged twats; now I needed to cum desperately. I leaned back a little further with her in my arms, and began to gently slide my dick in and out of her tight little honey pot. It still clung to me like a too tight second skin, even after the brutal beating that it had just taken.

The feelings were so sudden and intense that audible human speech was impossible, so I just nodded an affirmation to my sibling. "I want you to cum for me Jack. Cum inside your girlfriend's little twat." She leaned back a little, opening her quim up slightly for a bit more of my length to fit inside her. She growled a little as she concentrated on making herself as tight as possible for me. She nibbled my ear, as she continued to talk dirty to me. "Oh god Jack. I want you to fill me up. Make me your slut... make me your little cum slut." My cock throbbed violently inside her. The combined verbal and physical stimulation was proving to be too much to handle. I was involuntarily moaning in earnest now, as I slowly began to lose control of my body. A tingle started in my balls, and rapidly spread to my stomach, and chest.
