It was just over two weeks ago that Susan revealed the extent of her shapeshifting magic to both me and Melissa. Just over two weeks since she first showed us what she could do with that new skill Lily taught her. Since then she'd only got more adventurous with the sorts of things she'd been willing to try while at home with me and Melissa. 

And for that matter I'd gotten a lot more adventurous too, when it came to the sorts of things I was willing to try with her. I'd done more kinky stuff in the last two weeks with Sue and Melissa than I could ever have dreamed of in my wildest horniest teen fantasies as dead-me.

It almost felt like every other night lately Susan was using her shapeshifting magic. She'd give herself a cock. She'd make herself taller or shorter, but mostly taller. Her boobs would get bigger or smaller, usually bigger. Giving herself a tail almost seemed sort of tame by comparison.

The end of her tail stayed firmly wrapped around my boob, she used it almost like a leash or something as she tugged and encouraged me to follow her into the bedroom. It maintained that tight grasp on me as I pulled my t-shirt off, then when I removed my bra I finally got a good look at the end of it.

Her tail had to be at least six feet long, and more than two inches wide at the thickest point. Out at the end it was down to an inch thick, and at the very tip it tapered down a bit more then ended in a blunt rounded shape. The whole thing was a pale pink colour, a shade or two lighter than bubblegum. The surface looked and felt like smooth soft skin stretched over a layer of muscle. And I mean strong, firm muscle. I had serious doubts whether I'd be able to pry it off me.

As I watched, the tip moved almost like a strong stubby finger while the rest of it maintained its firm grip around my boob. After a second or two the tip found its way to my nipple and started poking and rubbing it while the rest of the tail began squeezing and massaging my boob, sending electric shocks of pleasure up and down my spine.

"Holy shit Sue," I whispered as I felt myself getting wet. "This is... Wow."

She smiled and asked, "So are you going to finish undressing?"

I nodded slowly and pulled my leggings and panties down and off, and a moment later I was nude. She was still dressed, but not for long.

Her tail didn't let go of my chest, it didn't even stop doing that squeezing and rubbing thing, while she pulled her own top off then removed her bra. Finally she undid and removed her pants and panties, and I wasn't the least bit surprised to see the tail wasn't the only change she'd done to herself. 

I almost wondered if one of these days she'd just decide to keep the cock full-time, since she really seemed to enjoy using it on me and Melissa. It was soft when she stripped but it quickly grew hard once she revealed it. 

There was another little tug on my chest as she used her tail to pull me closer, then she wrapped her arms around me and pulled me into a hug. I could feel her firm shaft pressing against my belly as we stood almost face to face. At least she hadn't made herself too tall this time, she was only four or five inches taller than me.

I bit my lower lip but I decided to remind her she wasn't the only one with a tail. Without saying a word, I moved my tail down between my legs and up between hers. 

At some point over the last two weeks she discovered that using magic to grow a cock didn't mean she had to get rid of her vulva. It meant twice the fun, and gave me a chance to level the playing field. The spade tip of my tail found its target on the first try, and wriggled its way between her slick lips.

Susan's eyes half closed and she made a 'Mmmmmmm' sound as I pushed my tail deep into her. When I started flexing the spade tip in her, her grip on my left boob slackened a little but she didn't let go of me.

As my tail flexed and wriggled inside her I thought I was about to gain the upper hand, or upper tail anyways, when she cheated. Her arms let go of me and she reached up with both hands and took hold of my horns.

"Ah!" I gasped as the contact sent more electric shocks straight down my spine to settle in my groin. 

Her thumbs and fingertips started rubbing my horns while her tail continued squeezing and rubbing my boob, and I felt my knees start going weak. I tried to keep my own tail moving inside her, but it became harder to focus on that.

"Mara," Susan said in a quiet, serious tone. Despite what my tail was doing inside her, she still seemed to be able to focus clearly. A lot clearer than me anyways.

She didn't stop rubbing my horns or doing the tail thing with my boob, but she did slow down as she told me, "Remember if I ever get too intense for you, just say so. Just say stop if I make you uncomfortable or do anything you don't like."

Her voice had a sort of confident authority to it, like she knew exactly what she was doing and you just wanted to trust her and do what she said. 

I nodded slightly and mumbled, "Mhmm... I remember."

"Good girl," Sue said with a glint in her eyes and a predatory smile on her lips. 

She squeezed my horns a little harder while her thumbs and fingertips rubbed them a little faster, and my knees got weak as shocks of pleasure raced up and down my spine from my horns to my groin. 

There was no resistance in me at all as she used my horns and her tail to guide me to the bed. She turned me around then had me climb up onto the mattress on all fours, with my knees apart at the edge of the bed. The change in position meant my tail lost its place and slipped out of her, and I was trying to focus on remedying that. 

Susan had other plans however, as I suddenly felt the head of her cock pressing against my dripping wet labia. Any plans I had of concentrating on anything other than the sensations she was giving me were instantly forgotten.

Her hands firmly gripped my hips, and with one strong steady thrust she was deep inside me.

I moaned happily as the sensations shot through my body. 

Susan slowly slid herself almost all the way out, then paused a second. When she thrust back into me I let out another moan and my fingers curled into fists as I clutched the bedsheets. What started off slow soon built into a much faster tempo, and my moans grew louder while my breathing got more ragged. 

I didn't even notice at first that her tail had finally released its grip on my left boob. It wasn't till she wound it in a figure-eight around both my breasts and the tip started rubbing both my nipples that I clued in.

In what felt like mere seconds she had me almost at my peak. My eyes were half closed, every breath I took was accompanied by a lusty moan, and it felt like every muscle from my groin out to my fingers and toes was locked up tense in anticipation. 

And that's when she stopped. For a few agonizingly long seconds the only sounds were Sue's deep breathing and the little frustrated desperate noises I was making. 

She waited just long enough for me to begin cooling down, then started over. This time her hands left my hips and I felt her leaning forward. The soft warm weight of her breasts pressed against my back, then her hands grasped both of my horns.

The combined sensations of her shaft pumping into me, her tail manipulating my boobs and rubbing my nipples, and her hands on my horns was enough to rocket me well past the edge and practically into orbit. My brain short-circuited and I saw stars as I let out a long happy scream of ecstasy.

My magic-fuelled succubus girlfriend wasn't through with me yet though, and my mind-blowing orgasm only encouraged her to redouble her efforts. What I thought was the highlight of the night turned out to be just foreplay for my gorgeous redheaded girlfriend.

Susan pulled herself out of me then helped reposition me on the bed so I was laying on my back with my head on the pillows. I thought at first that was so I could relax and recover from the amazing sex, but it turned out she was just getting me into position for the next part of the evening's fun.

Once I was comfortable Sue climbed up ontop of me and sat straddling my belly. She had my hands at my sides, where they became trapped and pinned by her knees. I could still move my legs and my tail, but that was about it. Ok granted if I really wanted I could have gotten free, I had that whole demonic strength thing going for me after all. But maybe I didn't really want to be free.

My girlfriend leaned forward slightly so her long thick cock lay directly between my boobs. She grinned as her hands wrapped around my breasts and started massaging them, while simultaneously rubbing them against her shaft.

I moaned softly, my whole body was till tingling from my brain-numbing orgasm a few moments earlier. It seemed like something was missing though. A moment later I was reminded what it was when I felt the tip of Sue's tail gently force its way between my sensitive lower lips

My moans grew louder and once again I was completely at Susan's mercy. 

I might have had demonic strength, but the things she was doing with that powerful flexible tail of hers left my body completely limp. It felt like the tip of her tail was rubbing circles around my g-spot while the shaft twisted around to press and rub against my clit. And all the while she was still giving me a chest-massage as she used my boobs to stimulate her cock.

Once again it didn't take her long to get me right to the edge. Between her expert hands and her kinky tail, every muscle in my body was taut. My hands clenched to fists again, my toes curled, my back arched. And like before, instead of taking me over she just stopped and waited for me to start cooling down.

And once I started calming down she started right up again, she quickly got me to the edge a second time before she stopped. It was equal parts fun and frustration. I tried to get at her with my tail but with me laying flat beneath her while she straddled my belly didn't leave me a lot of options. 

There wasn't enough space between my belly and her bottom to get my tail under there, but I gave it a try regardless. I figured I could even cheat a bit, since I was still a lot stronger than her.

Sue grinned when she felt the spade tip trying to wriggle into position, and her own tail resumed its actions, as did her hands. I quickly lost concentration and was once again at her mercy as she brought me back to the edge in no time flat. And this time she took us both over the edge.

My whole nervous system lit up with the overwhelming pleasure and I was sure we'd get complaints from the neighbours about my scream of ecstasy as my entire body quaked and shuddered with the force of the orgasm that rocked through me. 

"YyyyyEEESSSS!" Susan shouted as her hips and groin twitched and spasmed. Her shaft was still squeezed in between my boobs, and I felt her hot sticky come spurting all over the top of my chest and my neck.

At long last, her tail slipped out of me and she let herself slump over to the side. She ended up on her back next to me and we both lay there quietly as we slowly came down from the pleasure-high.

"That was good," Sue commented after a few minutes. "We should do that again."

"Mmmmmmmmm," was about the best I could manage.
