"I can't believe we just did that!" she gasped, "We just stopped in a truck-stop and let two perfect strangers spurt their cum down our throats! God, you're a fucking horny cow! I've never met anyone like you before!"

"Wait until we get into the park!" I warned her, "You're gonna have a really good time when we get somewhere quiet in there - I promise you!"

Twenty minutes later we were pulling up on the car- park, under the deep shade of some trees inside the city park.

"Well Suzy, what little treat have you got in store for me now?" Fiona asked.

"I thought you might like to take a little walk - with a slight difference?" I replied.

"I've a feeling I shouldn't ask you this, but what's the difference?" she asked.

"It's what I'd call a 'nudie-walk' in the park!" I replied, "You take off your bra, hold your coat together with your hands in your pockets, and go for a walk! Then, when nobody's around, you let your coat fall open to expose everything!"

"You're joking!" she gasped, "All I'd have on then underneath my coat would be my suspender-belt, nylons and my shoes!"

"Mmmm, I know!" I replied, "And later on, we take our coats off as well - c'mon!"

Fiona slipped out of her bra with more than a little uncertainty as I removed mine, then got out of the car and held her coat tightly closed while I locked the door.

"I must be out of my fucking tree!" she said, shaking her head as we both set off along the path, "But I've enjoyed what we've done so far, so I'll go along with it!"

"You'll be thanking me in a short while!" I smiled at her, "Mark my words!"

We walked along the path until we came to a signpost, several paths leading off and into the gathering gloom.

To the lake, the gardens, the nature walk, and the playing fields, were some of the directions the signs pointed to.

"Hmmm, the 'Nature walk' sounds interesting!" I mused, "How about we try that?"

"That's a narrow path through the woods that's nearly a mile long and finishes by the lake." Fiona told me, "But we won't see much in this light, it's getting far too dark!"

"That's what I'm counting on!" I smiled with a knowing wink, "C'mon! And now's the time to let your coat fall open - like this!"

I took my hands out of my pockets and the light and warm evening breeze wafted my coat wide open as we walked along, the only sounds being the 'clip-clop' of our heels on the path, and the 'swish' of our nylons as they rubbed together with each step!

"Fucking hell, this is crazy!" Fiona told me, "It's fucking sexy and it's really turning me on - but it's fucking crazy! I mean, what if someone sees us?"

"They won't!" I smiled, "Just put your hands in your pockets and pull your coat closed and - "Hey presto!" You're decent again!"

"Jesus! You're right!" she said, trying it for herself several times, "Hey, I'm really beginning to like this, Suzy!"

To prove the point, a few minutes later, a couple walked towards us and passed as we held our coats shut, neither of them seeing or suspecting a thing!

"Wanna take it a stage further?" I asked her.

"You bet I do!" she grinned.

"Okay, give me your coat and let me carry it while you walk beside me wearing nothing but your undies!" I told her, "Don't worry, I'll give you back straight away if we meet anyone along the path!"

Fiona quickly slipped off her coat and gave it me, her now walking along the path with me, wearing nothing but her white suspender-belt, lace-top nylons and heels!

"Well, how do you feel?" I asked her as we walked along.

"Like I'm about to come any second!" she admitted, "This is fucking fantastic! I'm sopping wet between my legs and my stomach feels like it's full of butterflies!"

"I told you you'd feel okay!" I said, "Now, just stop a minute and open your legs!"

She did as I asked, and I quickly squatted down between her feet before I reached forward and sucked noisily on her cunt-lips, licking the full length of her slit and making her jump as my tongue caught her sensitive clitty!

"Now, get down on all fours!" I told her. She quickly got down and I went round behind her and pressed my mouth against her bulging cunt-lips before parting them with both hands, then pushing my tongue deep inside her!

"Oh yessssss!" I heard her breathe, as she pushed her hips back at me and wiggled them, "That feels fucking wonderful, Suzy!"

It only took a second for me to pull my mouth off her juicing cunt and to kneel down behind her before I slid my rigid cock into her cunt, making her gasp as I reached under her to cup each of her tits and slide in and out of her!

"Oh my God! I'm being fucked in a public park like I was a bitch-on-heat!" she gasped, "Right here in the middle of the fucking path!"

"And like a bitch-on-heat, your cunt's soon going to be filled with cum!" I gasped as I felt my spunk rising, "In fact, right now!"

She dropped to her elbows as she felt my cock jerking inside her, spurting my cum deep into her cunt, all sense of decency being abandoned as the overwhelming feeling of lust at being shagged in a public place for the first time in her life overcame her!

"Oh my sweet fucking Jesus!" she moaned, "This is beautiful! Fuck me Suzy, fuck me like the bitch-on-heat that I am!"

"I only wish I could 'knot' with you Fiona!" I told her, remembering how Paddy knots with the girls back home as I finished spurting, "Now, stand up! Because I'm not going to lick you out like I normally do, I want you to walk alongside me and feel my cum running down the insides of your thighs like a bitch that's just been fucked!"

"Oh yes!" she gasped, her voice now filled with lust, "I am a bitch-on-heat! I really am! And if a dog had to come along right now, he could take me - right here!"

Unfortunately, there were no dogs around! Otherwise...

She stood up, a cocktail of my cum and her cunt-juices instantly running out of her and flowing down the insides of her thighs!

"Christ, that feels sexy!" she breathed as we set off again, my semi-hard cock slapping against my thighs and drops of my cum splattering onto my stocking-tops!

"Can you feel my cum running down your thighs, Fiona?" I asked as we approached the woods, "Tell me how it feels!"

"Mmmm, it feels cold, sticky and wet - but very sexy!" she replied dreamily, "I feel like I've been 'taken' or 'raped' without any of the violence and in a very nice way!"

We carried on along the path for a few more minutes, finally walking into the gloom of the overhanging branches and sitting down on a bench where I pushed her back and squatted between her thighs, lapping up my cum that still oozed from her gaping cunt!

"Did you mean it when you said that you'd let a dog fuck you if one were to come along and catch you on your hands and knees?" I asked her before licking her juicing gash and nibbling on her erect clitty again.

"Mmmm!" she moaned, her head lolled back and her eyes closed as she drank in the feeling of being licked out in a public place, "It's always been a fantasy of mine Suzy, ever since being a teenager! I once tossed off my uncle's dog and was amazed at how big it's cock grew! I was especially intrigued by that fantastic knot, and I remember playing with myself as I felt his cock throbbing, and feeling a really strong tickling sensation deep inside my belly and cunt, but because I was still a virgin at the time I didn't realise what it was - perhaps that was my very first orgasm, I don't know?"

"Well if we find a dog for you tonight Fiona, your fantasy can finally come true!" I replied softly, "Our dog back home fucks and knots with my wife and her girlfriend regularly, and neither of them can get enough of him!"

"Oooo, stop it! You're gonna have me coming like crazy if you carry on talking like that Suzy!" she moaned, "The thought of it is really turning me on!"

"Seriously Fiona, if we find a dog tonight, we'll go somewhere quiet and I'll get him fuck and knot with you! And then I'll '69' with you and drink his cum as it overflows out of your cunt - just like I do back home with my wife and her girlfriend! How does that sound to you, would you like us to do that Fiona?" I whispered.

She didn't answer me - she couldn't! Her hands dropped down and gripped my head as her thighs tightened and trapped me between them, and I could feel her cunt pulsating as her orgasm ripped through her body and she groaned softly at the thought of this imaginary dog knotting with her and spurting his cum deep inside her cunt!

I sucked hard on her trembling cunt for several minutes before she finally loosened her grip on me, she then flopping back against the back of the bench to recover from what must've been a very powerful orgasm!

"C'mon Fiona." I said, pulling her up after a few minutes, "Let's go for a walk and see if we can find somewhere to fuck! The picture in my mind of you being fucked and knotted with a dog has given me a real hard- on!"

"Mmmm, so I can see!" she said as we set off along the path with our coats over our arms and going deeper into the woods.

"I laid in bed for three hours after you'd gone yesterday!" she told me as we held hands and strolled along the path in our undies, my new tits sticking proudly out and in front of me, crowned by my erect nipples, "And I put a couple of pillows under my butt to raise my hips so's your cum wouldn't leak out of me while I wanked myself to a fantastic series of orgasms!"

"And did it work, did it keep inside you?" I asked.

"Mmmm! you should've seen it dribbling out of me when I finally got up! I caught as much as I could in my hand, and then drank it before I took a shower! It tasted really fantastic because it was mixed with my own cum!"

"I know the taste well - it's sort of thick and sweet tasting!" I replied.

"And leaves you with a taste that makes you want some more!" she added.

We walked on and eventually came to the lake, having twice to put on our coats when we saw several couples approaching. They passed us with a casual glance - no doubt because of us being two women that were holding hands and not a guy and woman?

"Well I haven't seen any dogs to fuck you Fiona!" I told her as we sat on another bench, "So in the absence of the real thing, you'll have to be fucked on all fours like you're a bitch-on-heat, by me instead!"

"Aw, and I was so looking forward to getting knotted with one, but I guess you'll have to do instead!" she replied, "Perhaps if you barked as you fucked me?"

"I'll cock my leg up and piss on you afterwards if you don't stop teasing me!" I grinned, "C'mon, let's get between these bushes!"

We scampered up the banking and laid our coats out on the grass, Fiona immediately getting down on all fours and 'presenting' her cunt to me as though she really was a bitch-on-heat! I then knelt behind her and stabbed my cock at her rounded ass-cheeks, purposely missing the mark several times before plunging my cock in between her cunt-lips and rapidly fucking my full length into her!

"Oh yessssss!" I heard her mutter to herself, "Fuck me Rover! Fuck your beautiful cock into me and fucking knot with me - I want you so badly!"

I must admit that I'd had my doubts at first as to whether she was really serious about being fucked by a dog, but hearing her now and seeing the way she was acting, I was absolutely certain that if we could find a dog, she would actually let it fuck and knot with her - no doubt at all! She knelt there and took all I had to give her, her arms straight out and her thighs splayed slightly as I fucked her from behind - me stopping for a moment with my throbbing cock buried as deep inside her as I could get it, to simulate how a dog would feel if he was actually knotted with her!

"Come in my ass instead, Suzy!" she said as she turned her head and looked back at me, "I want you to fuck me in my ass and then come deep inside me!"

Not wishing to disappoint a lady, I pulled out of her cunt and eased my slick cock into her tight asshole, she pushing back and my cock slowly disappearing inside her!

"Oh yes Suzy!" she sighed as she felt my balls up against her thighs, "Now fuck me!"

I gripped her waist and thrust into her tight ass, my balls slapping against her thighs each time I thrust home, Fiona gasping with every inward thrust!

"Fill me! I'm your bitch and I'm on heat! Fill me with your cum!" she gasped.

Unable to hold back any longer I blasted my spunk into her ass, pushing everything I had into her as she pushed back with her hips really hard when she felt my cock rhythmically pulsating and spitting it's sticky load deep inside her!

"I can feel it! I can feel your cum hitting my insides!" she gasped, "Oh my God!"

She then dropped to her elbows and knelt there, my cock wedged firmly inside her ass and feebly spurting my last few drops of cum into her.

"Leave it inside me for a few moments Suzy!" she gasped finally, "It makes me feel like I'm being 'taken' or 'abused' when I can feel your cock inside my ass!"

"But I'd never abuse you Fiona!" I told her.

"I know that Suzy, but being in such a position as I am now, with your cock stuck deep inside my ass, makes me feel good - as though I'm a slut!" she explained, "I've never experienced the feeling of acting like a slut before - and I must say, like it!"

I did as she asked and remained wedged inside her cum- filled ass for another five minutes before she slowly fell forward and laid face-down on the grass.

"Mmmm, that felt sooooo good, Suzy!" she whispered, "You've soundly fucked me in both my ass and cunt tonight, all that's left now is for me to suck you off!"

"No problem, Fiona!" I replied, "You'll get your mouthful of my cum before the evening's over, I promise!"

"Thank you! But before that, lets have a ciggy and lie here while you tell me about your dog fucking your wife and her girlfriend!" she begged, "I want to know what to do if ever I manage to be fucked by one!"

I spent the next 20 minutes telling her all about being fucked by a dog, her hand dropping to her clitty and her drawing her knees up to wank herself as she listened.

And it was as I was explaining about sucking the dog off after he'd pulled out that she came, her whole body stiffening with the intensity of her orgasm!

"I think we'd better be making our way back." I suggested, "It's getting chilly!"

"Mmmm, it is actually!" she agreed, "Can we go back to your room?"

"That's just what I'd gotten planned!" I smiled at her as we put our coats on and walked back along the path, soon reaching the car. And it was as we were about to drive off when I noticed a fast-food trailer that was parked up at the park gates.

"D'you fancy trying your hand at a little flashing before we go home?" I asked her.

"Sure! What have you in mind?" she replied.

"Leave your coat unfastened and just follow my lead!" I told her as I put the car in gear and drove over to the fast-food trailer and parked up, where we got out and walked up to the stand, our coats flapping wide open and exposing our undies and naked tits to the world!

"Two burgers please!" I called up to the guy behind the high trailer-counter.

"Coming right up, lady!" he replied, nonchalantly throwing two slabs of meat onto the grill, before doing a 'double-take' as he held out his hand for the money and looked down at us to see our exposed tits and undies!

"Ummm... That'll be... ummm, $3 please!" he said with his eyes wide open.

"There you go! Three dollars!" I replied, reaching up and handing him the three dollar bills, my coat opening up and revealing even more of my near-naked body!

I heard Fiona suppressing a giggle as the guy took my money, him then having to tear his eyes away to put the money into the cash register.

"There you are!" he said, then handing us the two burgers, "Enjoy your meal!"

"I'd like some ketchup on mine!" Fiona said, reaching up to the high counter and taking hold of the bottle, her naked tits and suspender-framed cunt now completely exposed to the guy in the glare of the trailer lights, "Thanks a lot! See ya around!"

With that, we turned around and walked slowly back to the car, Fiona getting in and allowing her coat to fall open once more so's she exposed her naked right tit and the whole of her right nylon-clad thigh! I started the engine and drove slowly out of the park, Fiona falling into a fit of laughter!

"Did you see the look on his face when he looked down the second time at my exposed tits and cunt?" she giggled, "It was a picture!"

"I did notice that you took a long time with the ketchup bottle!" I laughed, "You're getting the hang of this flashing lark - aren't you?"

"Thing is, I don't even want a fucking burger!" she giggled, "I had enough earlier!"

We drove leisurely back through town, Fiona directing me along a short-cut through the lines of houses in the suburbs. A block from the hotel we passed an empty lot and something caught my eye, so I slowed down before stopping alongside the kerb.

"What are we stopping for, Suzy?" she asked.

"Can you see what I can see?" I asked, lowering the window, "Look over there!"

Just inside the entrance to an alley, was the dark shape of a dog!

"No... No, I can't see anything!" she replied slowly, scanning the area.

"Just inside the alley!" I replied excitedly, "If that's a dog and not a bitch, you could be having your fantasy come true!"

"Christ, yes!" she said, "I can see it! Call it over - quickly!"

I called the dog over and it looked up from the rubbish-bin it was inspecting, but then it looked down again, seemingly more interested in the bin.

"Hold on Fiona, I've an idea!" I told her.

I reached for my uneaten hamburger and tore off a piece, calling to the dog and throwing the scrap towards it. It watched the scrap of burger hit the ground and sidled over to it, gulping it down and looking up at me. I threw it another piece, but this time nearer to us, and the dog walked over and ate that piece as well! Tearing bits off the burgers and dropping them nearer and nearer to us, I finally had the dog sitting next to the car and looking up at me.

"You're in luck Fiona!" I whispered excitedly, "It's not a bitch!"

I slowly opened the door partway, offering a piece of the hamburger to the dog through the opening. Seeing the chance of another mouthful, he stepped up on the door-sill and half-stood inside the open doorway, wagging his tail.

I gave him another piece and stroked his head, him not seeming to object - in fact lifting his paw to 'ask' for another piece.

Offering him another piece with one hand, I cautiously slid the other under his belly and between his hind legs, my hand sliding along his furry sheath and pushing it back to expose his pink cock! I then slid my hand back and forth, him humping his back slightly after a few seconds, and then 'air-fucking' my hand!

"Offer him a piece of your burger - but not right up to his face!" I told Fiona, "Try to make him reach over me for it." She did as I suggested and the dog stepped over me and almost all the way into the car, taking the meat from her hand.

She tore off another piece and kept it even further away from him, this time with me slowly closing the door behind him and trapping him inside the car!

"Right! Now feed him the rest and make a fuss of him!" I told her as I drove off, pulling onto the hotel car- park and parking in front of my room only a minute later.

"Use your belt as a leash and we'll take him into the room." I suggested, Fiona doing as I said with me following her and the dog, then closing and locking the door to my room behind us.

"Well Fiona, d'you still want to try it?" I smiled, "Now's a good a time as any!"

"Let's go for it!" she replied, a broad grin crossing her face and her nodding her head!

We stripped off our coats and got some drinks before we laid on the bed, the dog jumping up and pushing his nose between Fiona's thighs, licking up her juices!

"Oooo, lovely!" she squealed as the dog pushed his tongue deep into her gash, forcing her cunt-lips aside in his attempt to lap up more of her cunt-juices, "If he does no more than this, I'll be really satisfied!"

"Oh I think he'll do more than that!" I smiled, "Let's toss him off first to see how big he's likely to get, then we can get you ready and see if he'll try to mount you! If he knots with you, you'll be on your hands and knees for a good half-hour, so we'd better make you comfortable first!"

"Can I toss him off Suzy? Just the thought of him mounting me is making me feel really horny!" she asked.

"Of course! But make sure you push his sheath right back so's we can get a good look at his knot! It's the size of that we're most interested in!" I told her.

She reached under his belly and wrapped her hand around his sheath, slowly sliding it back and forth and increasing speed as he arched his back and started to 'air-fuck' her hand. His cock was now totally exposed, pink and wet with a small bulge at the back end that was to swell, it's purpose being to swell to such a large size, it would prevent him from pulling his cock from the bitch and impregnate her with his cum!

His cock was already spitting watery pre-cum onto the floor and rapidly swelling as Fiona wanked him, the 'cock-part' swelling in thickness and changing colour to a purple, and his knot assuming the classic shape and hardness - already the size of a medium-sized tomato. He tried to grip her arm with his fore-paws as he curled his rear-end underneath himself and fucked his swelling cock back and forth in her hand, his hips now rapidly and powerfully moving back and forth!

Finally, she let go and we both looked down between his hind-legs to see a beautiful purple and red dog-cock jerking and spurting there, it now being fully erect and as thick as any man's erect cock! It was about 41/2 inches long, tapering to a pointed tip, roughly11/2 inches in diameter, with a hard and solid knot at the rear end that was roughly 2 inches across - altogether making his cock 6 or 7 inches long!
