Chris sat on the couch staring out the window onto the back garden glumly. The grey and rainy weather wasn't exactly out of character for our part of England, but something about it just had him down today. On the plus side, though, the sun was finally starting to poke out and it looked like we may have been in for some uncharacteristically pleasant weather. The downside, or so he thought, was that he wouldn't be able to take advantage of it. Since he and I had moved in, we'd been meaning to do something about the state of the back garden - specifically doing something about it being, essentially, a big plot of dirt. Normally this meant it was a bit of an eye sore, but after a bout of rain like we'd just had, it became a slice of heaven for Chris.

Chris, of course, thought his secret was safe. But, unlucky for him, he'd left his laptop open a few weeks prior and forgotten to close out his web browser. Naturally, I went to play a harmless prank on him, change a social media status or make his home page a gay porn site, something of that nature. But when I flipped the screen up to see what was open, I found he was already on a fetish site. As I glanced over the chats he'd left open I found that not only was he also into guys, but that he had a... unique... fetish. If someone had told me about it I imagine I would have been slightly off put by it. But as I read the descriptions of what he and whoever he was chatting with were fantasizing about doing to each other I felt a stirring in my loins that quickly spread through my whole body.

Flash forward back to the day in question, and as Chris was staring I couldn't help myself. I'd thought about telling him I knew his dirty little secret, but this seemed like a much better way of letting him know the cat was out of the bag. Or, in his case, the pig was out of the sty.

"What're you staring at out there?" I said teasingly, startling him from across the room.

"Just, um, thinking about the garden, it's a right mess after rain like this and I was thinking about how we could sort it out," he responded awkwardly. If I hadn't known his secret I wouldn't have thought anything of him being startled, but armed with my knowledge of his fantasies I knew exactly what he'd really been thinking about.

"Sort it out? I thought it was already just the way you like it." The teasing in my voice changed from innocently playful to something much, much more lascivious as I spoke with a widening smirk.

"W- what do you mean, just how I like it?" Chris stammered, visibly caught off guard. "Our neighbors must be appalled by the sight of that- that pig sty!" As he spoke his arousal became more than a little apparent as his growing bulge gave him away. "If I was a pig, though, you'd have a hard time keeping me out of it," he said, realizing he was as good as caught when his eyes followed my gaze down towards the growing tent in his trousers.

"It would appear somebody is already having a hard time just thinking about it," I replied, joining him on the couch and groping his crotch shamelessly. "You like the thought of being a pig in that muck, don't you?"

Chris gasped as he felt my hand on him and I could see in his eyes that he was feeling the same pounding of the heart and churning of the stomach that I was, nervously anticipating what we both thought was about to happen. After a moment though, he broke the silence. "I'm absolutely wild for it," he said with a gleeful smirk. "And if I'm not mistaken," he continued as one of his hands found its way down to my crotch, finding my own burgeoning erection, "you're wild about it too."

"Well in that case, what are we still doing in here with all these pesky clothes on?" Before he can respond, I press my lips to Chris', capturing him in a passionate, lustful kiss. My free hand begins exploring his body, learning the form I'd quietly been watching since we first moved in together, while my other hand continues to grope and caress his growing bulge. His hand runs through my hair as we embrace, his other hand still on my crotch and returning each motion mine gives to his. I feel a slight pause in his motions as he realizes the size of my bulge, but after that pause he returns with even more vigor.

Eventually we do make our way towards the garden door, though the kissing and groping slows our progress slightly. When we reach the door we help each other strip down to our boxers, revealing ourselves in a new light. Being roommates the sight of each other half naked was nothing new, but in this context it felt so much better. When Chris turned around to open the door, I couldn't hold back and in one smooth motion, dropped to my knees and pulled down his boxers, leaving his perfectly formed ass directly in front of me. Without hesitation I begin kissing and brushing my tongue over the beautiful cheeks, relishing in the small gasps of pleasure I was drawing from Chris. I quickly move from just the cheeks, to pressing face between them to give the same treatment to his twitching hole. His gasps grew louder and he began to moan as I savored the taste of his hole.

"Fuck I've been wanting to do that for ages," I panted out when I finally pulled away from his ass.

"I've been waiting for you to do it," he replied with a teasing smile. He led us out to the sodden patch of earth that would soon become our very own wallow. "I hope you'll do that again in here."

"I think I can manage that, my sweet dirty piggy," I smirk back as I pull Chris in for another long kiss and my hands slide down his boxers to grope his ass and tease against his hole. He embraces me again and as we kiss he begins moving us out into the muck, each step deeper than the last until we're in the middle of the garden and we're shin deep in soft, cool mud.

"Looks like someone is eager to get wallowing," he teased as he massaged my cock through my boxers and my hands gripped his ass hungrily.

"I think you might want to get wallowing even quicker." I slide one hand up to his chest as I kiss him again. My other hand slips a finger into his hole and as I feel him gasp and tense up against me I pull that hand away and give him a quick shove against his chest. He landed in the muck with a heavy splat, spraying thick, earthy muck everywhere. By the time he righted himself he was covered up to his shoulders in beautiful mud and while I was distracted admiring the sight of his body coated in muck he seized the opportunity to grab my legs and tackle me down into the mud. My shocked cry as he tackled me quickly turned into a moan of heated pleasure as I felt the muck embracing my body, coating my skin with its filthy stain. Once the heated shock had passed I pulled Chris to me and mashed our lips together again as we began rolling and wallowing in the mud.

Soon he slipped a hand down the front of my mud coated boxers and began to stroke me, dirtying one of the only clean parts I had left. As he stroked me I responded in kind, shoveling as much muck as I could down the back of his boxers, filling them completely. He let out a cry of filthy delight as he felt the muck mushing around his cock, balls, and ass, surrounding and coating them.

He quickly pulled away and turned his back to me and removed his boxers, revealing an ass that was even more beautiful now it was covered in dark muck. He bent over and plunged his head into the mud, sliding his whole body down into the mire before rearing up his ass, now coated with an even thicker layer of mud. I immediately pounced forward and buried my face in his filthy ass, moaning loudly as I felt the thick layer of muck covering it smear all over my face.Pleasure and arousal surged through my entire body as I felt the mud coating me. Completely controlled by lust I licked, kissed, sucked, and tongue fucked his entire ass, pulling away from savoring the taste of his tight hole to give the same treatment to each of his muddy cheeks. With each pass I could feel him twitching with pleasure, his hole tensing as his cock reared up.

"You're such a horny pig," Chris said, grinning ear to ear when he finally surfaced, face now coated with muck like the rest of him.

"You're hardly one to talk, piggy," I replied before dipping my head down to drag my tongue up the length of his muddy cock, over his balls and back up to his twitching hole. "Not that I'm complaining about that."

Chris smirked back at me before slopping a fresh layer of muck onto his ass and shoving his face back down into the mud. Knowing exactly what he was saying without words, I gleefully planted my face back in his freshly muddied ass and continued letting my tongue and lips do as they pleased, occasionally letting myself drop back down to his cock and balls before returning to his ass. My tongue worked wonders on him, making him quiver and moan into the mud.

He freed his head from the slop once more, he turned to me. "Fuck my ass, you horny pig," he moaned, before collapsing back into the slop with a splat, semi submerged and prepared to brace against me.

"My, my, it would appear I'm not the only horny pig in this wallow," I smirked as I pulled away from his ass. "You want me inside you my dirty little piggy?"

"Pound me with that giant muddy cock," he grunted, stroking himself as he waited for me to push into him.

"That's not what a piggy says," I smirked as I laid back in the mud, my erection bobbing tantalizingly above the surface.

Chris planted his face into the muck again before rearing up, his features now coated with fresh mud. "Oink!" he replied delightedly.

"That's it, oink for me sweet dirty piggy." I lifted myself up and dragged my tongue up his ass once more before teasing the tip of my cock against his tight muddy hole. He let out another heated oink as I slopped more mud onto my cock to act as lube as I pushed it into him. We both moaned in ecstasy as my huge erection stretched and filled his tight muddy hole. I moved slowly but surely, letting him adjust to my size as I buried the entirety of my muddy cock into his muddy ass. I accelerated my thrusts bit by bit, sinking us into the muck as I pounded into him. As we drew nearer and nearer to the brink I slowed my pace, drawing out the pleasure, before pulling out. "I want you to ride me in the mud piggy, then blow your load all over me as I fill you with mine. Can you do that, piggy?"

He oinked his reply before pushing me down onto my back in the slop. I watched as he dropped a heavy pile of the soft mud onto my face before feeling him do the same to my crotch. Then a moment later I felt him steady my cock and sit down onto it, taking it all in one smooth motion. He quickly began moving faster and faster, bobbing up and down and milking my cock as he plastered us both with more mud.

"Fuck- that's it piggy... oink for me and cover me with your cum..." I groaned out as I drew nearer and nearer to a beautifully muddy orgasm. Not a moment later he let out a loud oink as he came all over me, his cum splattering all over me and even splashing against my chin. The sound of his grunting and oinking combined with his cum shooting out onto me pushed me over the edge and I cried out as I pumped pulse after pulse of hot cum into him, filling him to bursting with my seed. I pulled him down for a muddy cuddle as we savored the warm afterglow of our orgasms.

"How was that piggy?" I asked, breaking the silence after a few minutes of feeling him laying close to me and gently smearing mud across my abdomen.

"Oink," he replied with a grin before splatting more mud onto my face.

"I think living in this house just got a lot more interesting," I replied with a naughty smile before pulling him in for another muddy kiss.
