She approached my fully engorged stiffness, looking at it closely, almost drinking it with her eyes, and then paused. She was confused a little at first by her genetic desires, but she figured it out shortly and hesitantly kissed the head. Then she looked up at me to check for approval. I smiled and nodded for her to continue, and she did. She kissed it slowly, then paused, trying to understand what her instinctual urges were telling her to do. Then she opened her mouth and stuck out her tongue a bit, moved closer, and licked the tip.
The taste of her own depths mixed with my semen must have been the first flavor she ever experienced, and after pausing a moment to experience it, she smiled a beaming smile and licked it until there was nothing left to taste of our previous encounter. By that time, I was starting to warm to the encounter again, and I noticed she was concentrating her licks on my opening, where more pre-come must have been making itself known.
"Mmm, I like this..."
"I do too," I replied. "But when you put it in your mouth, make sure you don't touch it with your teeth."
"Ok," she said.
Then she opened her mouth and took in the head, and I felt her tongue on it as her mouth close. She moved her tongue as though she was sucking a hard candy.
"Mmmm," I moaned. She saw my response, and was encouraged to take more of it in. As she did that, she realized that she wanted to suck it in further and imitate in her mouth the movements it had made within her pussy. She began giving me a blowjob and I couldn't believe how good it felt, especially coming from someone who had never given one before.
Soon she had forgotten to worry about hesitation and seeking permission and she was busy enjoying herself with this new experience. Back and forth went her head, alternately taking me in and releasing me from her mouth. She varied the speeds and depths, experimenting, but never once did I feel teeth on my sensitive member. It was almost as pleasurable as her smouldering sex had been a few minutes ago. I closed my eyes for a few minutes and just stood there enjoying the sensations she was sending through my body with her cute little mouth. Just as I had specified, she had full, pouty lips, and boy did they feel good.
She continued on, exploring different techniques for a bit, doing different things with her tongue, trying different angles, different speeds, and then she tried to take all of me into her mouth at once. Amazingly, it slid down her throat without the slightest gag reflex, and when she noticed the surprise and pleasure on my face and heard the sudden involuntary gasp I made, she decided that this was a Good Thing, and started taking me down her throat rythmically. I could not believe how good it felt! I had never had such an amazing blow job. She continued, and I closed my eyes and started involuntarily thrusting my hips to meet her as she swallowed me with each thrust. Her response was to speed up a bit, and I sped up with her, until I was fucking her mouth as fast and as hard as I had been fucking her pussy not long before.
It wasn't long before I was making involuntary sounds in response to my rapidly growing pleasure, and she began to make sounds of her own. Her sounds indicated to me that - somehow - she was on the verge of another orgasm of her own. Was she built to come whenever I did? The thought passed out of my mind as fast as it had entered, because there was just too much pleasure to be able to think straight at that point.
I felt the seeds of my orgasm start deep within me. I put my handa on her head and began guiding her down onto my now raging erection, again and again and again. This only seemed to infuriate her own arousal, and a split second before I came, she stopped moving and began shaking violently as she achieved another fantastic orgasm. Mine came with an explosion from my cock that came out so hard it must have shot right into her stomach. Her body was moving almost convulsively to her own monstrous release. I groaned long and hard as my peak washed over me with the force of a tidal wave, my hardened length twitching powerfully in her mouth.
"Oh my god, woman!" I said, after catching my breath. "That was amazing!"
With her own final twitches of pleasure going through her body, she sighed out her nose, my manhood still in her mouth. Smiling as best she could, she looked up at me, gave my cock a few more strokes with her mouth, and then released it.
"I am supposed to please my owner," she said matter-of-factly. "Can we have more sex now?"
She returned to the position in which she had first settled herself on my bed when we came in. Her pussy and hips were swollen with blood and desire, and despite my just having had two majorly powerful orgasms, I found that the sight of her sex reversed any thoughts my dick had had of shrinking. Before even finishing it's softening, it grew fully erect again. Just as before, the faint scent of female in heat wafted past my nostrils. There was such a surge of sexual response in me that I knew she must have been genetically modified to have extremely potent sexual pheromones.
