David's Magical Body, by Josh Dugan

David was mad about me. I was mad about him, too. He could pour his body onto
mine, and it felt like I was being drenched in fresh cream. His touch was
light and cooling, and at the same time warm and relaxing. 
What I hadn't known early on was the magic he had in his wonderful body. His
beauty gave some hint of it, especially the sweetness of his smile and the
dexterity of his long, slender limbs.
He never let on that he was magical until I discovered it in a moment of
 lighthearted wrestling on the bed. I had him pinned pretty good, but then he
grabbed my wrists, so  I was trapped. It took a moment for me to realize how
he did it, because I had already grabbed his wrists. But how did he do it? It
didn't make sense.
"Hey, let go!" I said. He let go of my wrists and I let go of his, and he
rolled over on his back, smiling his beautiful smile as I straddled him with
my knees. His hands hung there relaxed at the end of his arms -- four of
them! I was startled and kind of shocked - but also turned on! They were
beautiful, sexy hands. But he only had two arms when we started wrestling.
"I'm magical," David smiled, reading my mind. "Here, feel them, they're
real," he said putting his four hands in mine. They were warm and gentle -
and strong. I had to kiss them. "I can shift my shape, but I only do it for
the one I love," he smiled.
"Wow," I said. "That totally turns me on. I'm hard as a rock!"  "I hoped you
would be," David said. "I'm glad it turns you on, and it makes me hard, too!"
"Can you stay like that?" I asked David. "I'd love to make love to you like
this!"
"Of course!" he said. "Anything for my love!"
I had to fuck him in the worst way! He lay on his back and parted his
beautiful long legs to let me enter him,  guiding me into him with his hands
while his second pair held my shoulders. I held the arms that supported my
shoulders, bending my neck down to kiss them. We rocked and groaned as I
became more and more aroused inside his warm male ass, and his hardon grew
huge and shiny as his chest and neck became flushed with arousal. "God, I
wish I could suck you while I'm in you," I said. "I'd love for both of us to
come together!"
Between his heavy breaths, David smiled and said,"Grab me and pull me to your
lips." I looked at him doubtfully, but he smiled encouragement. I grabbed his
beautiful cock in my hand and gave it a good pull -- and with some
resistance, it was able to reach my mouth -- the thing actually stretched,
making it even sexier, and the head and shaft grew larger in my grasp. It was
wonderful in my mouth! And I was in him at the same time. I had to come so
bad!
David was groaning and moaning, with tears in his eyes. "Please!" he gasped,
"Let me come into you, too, while you're in me and you're sucking me!"
"Sure," I said, breathing hard. "I'll swallow everything you've got!"
"Thanks," David panted, "but I want to be in your ass too while you're in
mine and while I'm in your mouth. I'll need to add a second pair of legs and
a second cock to come into your ass -- okay with you?"  I was so turned on I
couldn't speak. "Mmm-hmm" I hummed, around his huge cock in my mouth. "Oh!"
he cried. "It feels good when you say mmm-hmm on my dick!" I laughed, but the
next thing I felt was his second pair of legs, the thighs warm on my back and
his  second hardon going into my ass, smoothly torturing my ass and my
prostate as I ached to come! And we came! Hot, wonderful come shot into my
grateful mouth from David's first hardon, and I felt my ass distended and
lubed with burning thick come from David's second hardon in me!  I fucked his
beautiful frontal ass and pounded my love and arousal into him for all I was
worth, my whole body saying to David I love you, I love you, I love you!
We came and came, and came and came some more. I was exhausted but still
aroused when we were through, as I lay on his beautiful chest, his gentle
four arms holding me. I kissed David's beautiful lips. After a long,
wonderful kiss I was incredibly turned on again. His eyes met mine. 
"I've pumped my magic into you," he smiled. "I hope you don't mind, but I did
your first magic for you. Would you like to come again?" He indicated my legs
by a look at them. I raised myself up a little and looked at  my legs. Four
of them lay there on David's four, with my first hardon and a new second one
between the back pair of legs, both raging and aching to come. I kissed David
again and worked my four legs, feeling my hardons huge and urgent. "Yeah,
David," I said, hornier than I have ever been. "This could go on all night!" 
As a matter of fact, it did!
