Hello everyone this is IndigoWerewolf with the next chapter of Old Friends, New Tricks. Before I start the story, I want to wish everyone a Happy Thanksgiving. Now that that's out of the way, let's read and I do not own Left 4 Dead!

*Zoey's POV*

My mind felt hazy as I rose out of my slumber and opened my eyes to see that Ashley wasn't lying next to me. My head was too fuzzy to ponder why however, and I stretched my stiff limbs, feeling my joints stretch and pop. I sat up rubbing the back of my neck, and the blanket fell off to reveal that I was wearing a loose white T-shirt, which confused me since I could have sworn that Ashley and I had both slept nude last night.

I shrugged as I changed into my pink jacket and some jeans along with a black Minecraft T-shirt. As I got dressed, I looked out the window to see that it was a bit past noon, and I walked through the hall to the bathroom to brush my teeth. Once I reached it, I looked in the mirror and was shocked. I had changed significantly, my skin still pale but no longer inhuman. My eyes were the same, but on my forehead sat two short, curved horns like a demon's, looking to be the same gray color as my skin used to be.

My hand rose up to them and I hesitantly felt them, and sure enough they were real. Suddenly, my eyes widened as I remembered what Kevin had told me when Ashley went into hibernation, and I looked down at my legs in a panic. I then breathed a sigh of relief as I saw that they were still normal, and I reflected that they were probably better since I could walk easily again.

I then looked to my hands, which now lacked the claws of my former form. Remembering what Ashley had showed me however, I flexed my fingers and watched as they emerged from my digits. Instead of being bone like hers however, they were still made of claw, and were thicker and shorter, with a slight curve. I relaxed and let them retract, and looked back into the mirror.

I sighed as I realized that I must have undergone my own Metamorphosis, and was now a Maverick. "Why aren't my legs bent backwards, though?" I asked myself out loud, and my hand went to my throat as I realized that I could speak with ease once more. I was baffled about my predicament for a moment longer, but it was pushed out of my mind as I noticed that my eyes were glowing faintly.

I groaned as I realized what it meant and a slight heat washed over me that I hadn't noticed before, concentrating itself in my groin. "Great, on top of it all, I'm in heat." I muttered, and mentally cursed every human friend in high school who told me they were jealous of me for going into estrus instead of having to deal with a period. 'This is going to make things awkward.' I thought to myself as I brushed my teeth, and once I was done, I walked downstairs to see that Annie was eating a bowl of cereal.

She looked up and smiled at me as I walked into the room, and told me, "Nice to see you're awake." I smiled back and replied, "Nice to be awake. How long have I been out?" Annie giggled and told me it had been about a week, and I asked her, "What's so funny?" Still giggling, she replied, "Sorry, it's just that I've never heard your voice clearly before." I smiled wryly and asked, "Where's Ashley?" Annie's smile fell as she told me, "She barricaded herself in the guest room five ago, and won't come out. She won't tell me what's wrong either."

I frowned worriedly as I muttered, "I'm going to check on her." I turned to leave the room, but before I could, Annie stopped me and asked, "Hey Zoey, are your eyes glowing?" I blanched at the question and nervously replied, "N-no, must be a trick of the light. Why do you ask?" In response, Annie got a worried look and told me, "It's just that Ashley's eyes looked like they were glowing before she locked herself in the guest room."

Hearing her words, I turned around and ran towards where Annie had told me, thinking to myself, 'Of course, how could I not realize Ashley is in heat too? We're both catgirls, for Pete's sake! And if she's been feeling it for five days, then she's got it bad.' An anthro's heat got worse the longer it went unsatisfied, and although there were medications to suppress the symptoms, there was no way Ashley or Annie could have gotten some since I had gone into my Metamorphosis. I shuddered as I remembered the time Ashley had forgotten to take the meds, and pounced on me after I had worriedly gone to check up on her after not seeing her for three days.

Once I reached the door to the room where Ashley had locked herself in, I knocked on it and said through the door, "Ashley, it's me, Zoey. Let me in." There was no response for a moment, until the lock quietly clicked open. I turned the doorknob and opened the door slowly, to see that the room was dark, and that Ashley was sitting on the bed, naked and fisting the sheets tightly. Her cheeks were red, her eyes were glowing, and the room reeked of her pheromones. On the bed, she panted hard as she looked at me longingly.

I worriedly asked her, "Ashley, are you okay?" My words set off a round of trembling across Ashley's body, and she told me, "Zoey, you need to leave." My eyes widened at her words, and I exclaimed, "What?" Ashley's trembling was getting more violent as she told me, "I don't know how long I can hold myself back. Please, you need to go." I gave her a stern look as I walked up and told her, "Ashley, I'm not going anywhere. I'm staying here to help you through this."

Ashley shook her head violently and told me, "No, you can't stay. Neither of us has ever been this bad, and I don't want to end up hurting you." Her panting and trembling had increased as she spoke, and I could smell her pheromones permeate the air even further as she undressed me in her mind.

Hating to see her like this, I told her, "Ashley, we're both in heat. If we don't take care of it soon, we'll just get worse and worse until we lose our minds, and if we do, we might really hurt each other, or even Annie." Without letting her reply, I started stripping down, walking towards her as I did, and continued, telling her, "We've always helped each other when we go into heat, and I'm not going to abandon you when you need me most."

*Warning: Lemon Alert*

The glow in Ashley's eyes intensified as they roamed my body, and I could see my own glow strengthen by the blue hue on her skin where I was looking as I did the same. I climbed onto the bed and crawled up to her, and as Ashley opened her mouth, presumably to protest, I leaned forwards and captured her lips in a fevered kiss, forcing my tongue into her mouth as her body tensed, then relaxed. We both moaned fervently as our hands roamed each other's bodies, and she shuddered as my fingers slipped down to her pussy, not wasting any time.

I broke our kiss to nibble at Ashley's ear, and she moaned loudly and leaned into my touch as I pumped my fingers in and out of her, and I did the same as I felt her own appendages rub my labia. We panted as our fingers pumped in and out of each other's sex, and I maneuvered our bodies so that we were lying on our sides facing each other. I moaned out in pleasure as I felt the pleasure building in my body come to a peak, and Ashley and I cried out simultaneously as we both reached our peak.

When we had both come down from our orgasms, we lie next to each other panting, and after a moment, Ashley panted out, "Not…enough." I growled as I agreed, and I heard a gasp from the doorway, and turned to see Annie standing there with her hands over her mouth.

Suddenly I felt the heat in my body intensify and Ashley and I shared a look, having a silent conversation. 'We're not dragging her into this.' I told her with my eyes, and she silently replied, 'Neither of us are going to get through this with just the two of us, and you heard her touching herself listening to us the night we got here. She wants us, too.'

I sighed lightly and told her, 'Okay, but how do we go about it?' Ashley got a knowing smile as she replied, 'Like this.' Suddenly, she leapt up and rushed toward Annie, who ran off in a panic. "Ashley!" I shouted out, and followed the both of them through the house. I ran down towards Annie's room, following my mate and the mousegirl. I caught up with them once Ashley caught her in the living room, and as Annie struggled to get out of her grasp, I put my hand on her shoulder and told her, "We can't force her into this." Ashley looked up at me and smiled at me, then replied, "Don't worry, by the time I'm done, she'll be begging for it."

Before I could say anything, she went back to Annie and began kissing her neck and fondling her breasts through her shirt. Annie squirmed at her ministrations, and I sighed and told Ashley, "Ashley, stop. It's obvious she doesn't want to do this." Ashley turned to me, but before she could say anything, Annie quietly told me, "But I-I do want to do this." Ashley and I both turned to her, and after a moment, I asked her, "You do?"

With a heavy blush on her face, Annie nodded and told us, "I've been attracted to you both since I first saw you, but I felt guilty about it since you were together, and I didn't want to act on it since I was afraid I might accidently break you two up. But, if you want me too, and if you need this as much as you look like you do, then I want to do this." I smiled down at her and seductively told her, "Well then let's get started."

I then reached down and started fondling her alongside Ashley, and slipped my hand underneath her shirt and bra, then began rubbing her bare breast as I kissed her jawline. Annie moaned at our touches, and as I slipped her upper clothing off, Ashley and I both began sucking on one of her tits, her moaning all the while. When I couldn't stand the burning in my pussy anymore, I moved down towards her lower body, and saw a strange lump in her pants. Curiously, I unzipped her pants to see a hard length barely contained by her panties.

By this time, Ashley had joined me, and she pulled her panties down to reveal Annie's throbbing erection, complete with two testicles, with her pussy sitting behind them, the entire region shaved bare. In surprise, I looked up to see Annie was trembling, and looked like she was about to cry. Suddenly, she told us, "I'm sorry, I-I forgot to mention this to you. You don't have to say anything, I know I'm a freak."

At that, her body was wracked with sobs and Annie covered her face in shame. I frowned at her words. Hermaphroditism was a rare condition, especially among anthros, and many saw it as something to be despised, especially among religious groups. To reassure her, I kissed away Annie's tears and told her, "You're not a freak. You're beautiful." Annie looked up and sniffed, then told me, "You don't mean that." I smiled at her and told her, "Yes I do, and I'm going to prove it."

I then slid down her body back to her penis, and took it into my hand, bringing a moan from Annie. I pumped my hand up and down, marveling at its size. The phallus looked to be nine inches, at least, and looked especially huge on her small frame. I then took the head into my mouth and started suckling on it, bringing more moans from Annie, and worked my way down her length until my nose was pressed against her shaved crotch. I pulled up and once only the head was in my mouth, I plunged back down and started bobbing my head up and down her cock.

Annie moaned loudly as I sucked her, but was silenced by Ashley kissing her. Annie started bucking into my mouth, and I held her hips down with my hands, and continued sucking on her cock. Suddenly, she let out a loud moan and erupted in my mouth, her cum rushing forth and filling my mouth to overflowing. With difficulty, I swallowed it and cleaned Annie's cock off, then, pumping her still-hard cock, looked up at her as she panted, and asked, "Still don't believe me?" Panting, Annie shook her head wordlessly, and I giggled as I lined my pussy up with her cock.

"Get ready." I told her, and sunk down on her cock until she was completely hilted in me, and rose back up as we both moaned. I began bouncing up and down on her cock, and closed my eyes as I fucked myself on her penis. Suddenly, Annie's moans became muffled, and I opened my eyes to see Ashley riding her face, and she and I wrapped our arms around each other's shoulders as we leaned in for a hot kiss as we both rode Annie.

Suddenly, Annie began thrusting her hips up to meet mine, and I moaned loudly at the increased pleasure. Ashley and I made out furiously as I felt the pleasure inside me rise, and continue to rise as I rode Annie's cock harder. Then, the feelings in my body came to a crest, and I moaned out loudly as I came explosively. Annie couldn't take the increased tightness, and she moaned with me as her cock exploded within me, coating my walls with hot, creamy cum. Lastly, the vibrations from her moans brought Ashley to her own orgasm, and we all cried out as the three of us came. Once our orgasms ended, Annie, Ashley and I all collapsed to the floor panting. With a blissful smile on my face, I closed my eyes as I fell into a deep sleep, Annie's cock still twitching inside me.

*Ashley's POV*

I lay panting as Zoey passed out from the pleasure, and lifted her off Annie's cock and onto the couch in a comfortable position. Suddenly, I felt Annie push me so that I was bent over the arm of the sofa with my ass in the air, and her hands grabbed my hips as she slammed her cock into my pussy and started thrusting furiously. As she pumped into me rapidly, Annie leaned over me and told me, "I'm sorry Ashley, but I can't take it anymore. I've never done these things before and I need to cum."

After that, the only sounds that came from either of us were moans and gasps, and after about ten minutes, she hilted herself in me and shuddered as she unloaded inside me, the warmth causing me to reach my own orgasm. Annie didn't stop however, and resumed thrusting in me as we both moaned and groaned, and she brought us both to three more orgasms before we both fainted from the pleasure.

And there's the chapter. Until next time, read and review, but no flames!
