Nick pulled away and turned me over. In front of me was a large mirror. I gazed at the human form I had taken for my mission. I was a small skinny male with pale skin, blue eyes and blonde hair so light it was almost silver. Behind me was Nick, taller, darker and wider than myself. His hands moved to my white t-shirt and took it off slowly. Then he did the same with my jeans and underwear. Now I was naked in front of the mirror which now revealed my small cock and narrow hips. Nicks hands had moved to grope on my ass cheeks, squeezing and spreading them. I moaned as he did this and that only encouraged him to carry on.
Nick then knelt behind my ass, spread the cheeks, and I felt his warm tongue begin to dig into my hole. My legs began to feel weak and I bent over, my hands on the mirror as he continued to eat my ass. I made eye contact with my reflected form moaning and writhing on a humans tongue. He smacked my ass as he continued causing me to jolt each time but it felt good. After a few minutes Nick stood back up. I recovered a standing position of my own as he stripped off all his clothes. Underneath his body was well muscled and his cock was huge compared to mine. I began to salivate and Nick laughed "Like what you see?"
I nodded silently as he guided me down to my knees and coaxed my mouth open in front of his sex organ. Then he lightly grabbed my hair and pushed his cock into my mouth, the taste was overpowering. He moved his cock back and forth in my mouth, making low noises that indicated pleasure as he did so. I was beginning to lose higher reasoning as he used my mouth and by the time he pulled it out I was breathing quickly and licking at his full balls. Nick grabbed my hair harder this time "Ah ah boy I want to fuck your ass now"
I nodded and threw myself onto the bed. My head was in a pillow and I lifted my ass up for Nick to put his cock in.
"Please fuck me" I begged, wiggling my ass in anticipation for my first sexual encounter, of course this was for science, right?
I felt Nick's body climb in top of mine and his cock push into my ass. I cried out as he pushed deeper and deeper, breaking into my hole with patient force. He was balls deep now and thrusted in and out of my hole, causing my entire body to jolt and shake as he did so. I felt his powerful body pinning me down as he pounded my ass. I moaned and cried out at the feeling. His cock in my ass felt nice. This carried on for 20 minutes before Nick pounded my ass extra hard 3 times and ejaculated in my hole, it felt warm and soothing in my now sore ass. Then he pulled away and walked out of the room saying "That really was out of this world" as he left.
If only he knew how right he was.
