My body was going through a whole host of sensations as the moon began to rise for the night. Mostly, I felt warm and cramped. It was an odd sensation of pressure, like I was trapped within myself. It was like I needed to be free. I could feel some beads of sweat going down my body and I could see similar beads of sweat on Terri and Night, dripping slowly along their curves and disappearing down the deep valleys of their cleavage. On some level it made their skin glisten and served to further my arousal. I couldn't hide it, given that they had stripped me of my clothes, and the fact that I was at full attention. My penis was almost painfully erect. And it accompanied the feeling of being cramped within myself.
On some level, I didn't know how I knew what these feelings were and how I could tell my first transformation was coming. Maybe it was an instinct that was one of the unseen changes that had begun earlier. Regardless, it was not something I really cared about at the moment. The only thing that was really running through my mind at the moment was to be free.
"It's time, John," Terri said with a smile, "time to come frrrrrrree. Time to cha...nngee-uh."
Her voice was taking on a growling edge, or at least was starting to. I looked up to see her eyes beginning to change color, becoming more golden in color. I wanted to respond when I was hit by a fierce wave of pain.
"ARROONGH!" I gave a grunt.
It was fierce and radiated from within me. My skin was burning, but I was still rock hard. The crampedness was even worse. If whatever Night and Terri had planned to make it pleasurable, I wished they'd let me know what it was.
"I know it hurrrrrrrrrrrts now," Night gave a growling moan as she moved to crouch above me, "but it time, it'll always be pleasurrrrre... and forrrr tonight we help you feel good."
"HRRRRROOOW?" I gave a loud and pained moan.
"By feeling ourrrrrrr beasts come frrrrrrrree," Night gave a smile and moved her couch forward so that dripping vagina was above my face, "just as you felt Terrrrrri's last night."
I looked up to see Night's already large breasts begin to swell slightly bigger, her nipples moving toward the teat-like shape that Terri's had taken on the night before.
"LICK ME!" Night commanded.
I reached out and gripped Night's thighs to hold her legs apart. Then, using what arm strength I could muster, pulled myself up lick at her clit. I barely noticed my fingernails beginning to lengthen into claws and digging into Night's thighs. As as my tongue move to taste her juices, I could feel my canines lengthen slightly as they grew sharper and larger. I knew it was happening, but so far, the pain seemed to be excruciating. But they had said that the first was always painful, because my body wasn't used to it. I privately chalked that up to the line "no pain no gain." And that pain was there as I felt muscle groups enlarge, burning some layers of fat as it did so. The fact that Night and Terri had both burned away a large amount of fat tissue by becoming werewolves only served to make the pain worth it. I didn't have as much as they had, but I figured it would still take a few months of transforming before many of the secondary benefits became apparent... but even they weren't on my mind at the moment.
"OH... YES! YES! MORRRRRE, JOHN! MORRRRRRE!" Night howled out as I licked her.
Black fur was beginning to blossom on Night's body and cover her entirely. I could also see the beginnings of what would be her next two rows of teats beginning to form below her enlarging breasts. And in the back of my mind, I felt like I needed to. I gripped her tighter and fought through the pain to lick at her, swallowing every gush of sexual fluids from her clit. And then I felt it... Something warm and smooth and wrapping itself around my penis with great strength and force and MUCH greater pleasure. I glanced from the space between Night's legs to see Terri had turned around and "sat" down on my painfully erect penis. I was inside her again, and while she still felt extremely tight, if felt more like she was too small rather then too strong. I also noticed what looked like the beginnings of the skin that would form a protective sheath around my penis forming around its base, and very dark brown fur beginning to sprout on my body. For the moment though, that sheath wouldn't matter. I was too aroused for it to conceal my member. I reflexively began to thrust into Terri as hard as I could.
"YES! JOHN! BIGGERRRRRR! GRRRRRRROW BIGGERRRRRRR!" Terri howled as I thrusted into her, feeling her vaginal lips grip my member tightly and feeling it grow larger, thicker, longer as we continued.
"ARRRRRROOOOOOW...GOD..." I moaned out as returned my attention to licking at Night's clit with my tongue, which now seemed longer.
I could feel intense throbbing pain in my hands and feet as the bones in them began to lengthen and reshape themselves. Particularly the bones in my feet. They were altering to grow stronger and longer to give me a digitigrade stance when standing erect. I could hear the cracking noises as Night's and Terri's hands and feet did the same. I could also feel Night's hands shifting slightly as she placed them to the back of my held to push more into her nether regions, now surrounded by black fur. As Night moved her increasingly paw-like hands, I felt them brush my ears and then felt my ears reflexively twitch... and on top of it, my ears were no longer on the sides of my head. They were more toward the top.
"AARRRROOOOO YES... YES... YES..." Night howled out as I looked up to see her playing with her lowest set of breasts, which were rapidly growing to try and catch of with the rest of her breasts, "MORRRRRRE, JOHN, GIVE US MORRRRRRRRRRRE!"
I gripped Night's thighs tighter and licked her fiercely, even as going as far as to get my tongue fairly deep into her vagina. I also increased the intensity with which I was trusting into Terri. The pressure and trapped feeling that I'd felt earlier was beginning to die away as my form was rapidly becoming more and more wolf-like... or rather werewolf-like. It left a mental desire for freedom, but I could also feel the pain that was going along with it... Thankfully, Terri's tight grip on my penis and Night's juices were allowing me to ignore the worst of it. But the end was coming soon. It was near. I could feel it. I didn't know how I could, but I did, though, it wasn't like I cared.
"ARRRRRROOOOOWWWWW!" I gave a pained howl as the pain now centered on my face and at the end of my spine.
"LET IT OUT! CUM FRRRRRRRREE!" Night howled in response, "WE'RRRRRRRE ALMOST THERRRRRRRRE!"
I then watched as my face and jaw began to push forward, growing into a large wolf-like muzzle. My tongue still going in and out of Night's lower lips and brushing against my now much larger teeth, which were designed to strip flesh from bone... and maybe even crush bones themselves. My mind reveled in that. It was like I was nearly free... reborn...
"URRRRRRNGH!" I grunted as I continued to thrust into Terri, though now lifting myself up enough so that my but didn't hit the lawn furniture I was laying on when I finished each thrust. She was howling in ecstasy with each thrust I made.
"CUM FRRRRRRRRRRRRRRRRRRRREE, JOHN! CUM FRRRRRRRRRRRRRRRRRRRREE!" Terri howled as I began to hear some more slight cracking sounds as my spine began to grow additional vertebrae.
My own tail was starting to grow, and the back of my mind told me that once I had grown my tail, I'd be free. It was all my mind wanted and I increased my efforts with both Night and Terri to try and get my tail to grow. And then it happened. I felt my tail grow out beneath me, Terri's tail grow out and wag against the fur on my belly, and Night's tail grow out and wag against the fur on my chest. Night then climaxed, giving me plenty to lap up. Terri came as well, and what was more, I felt the powerful orgasm I'd ever had rip through my body as I felt my now much larger penis shoot load after load into Terri. I soon joined both of them in howling out my joy at transforming.
"AAAAAAAAAAAAAAAAAAAAAAWWWWWWWWWWWWWWWWWWWWWWWWOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOO!"
