Big Macintosh sat down in the shade, staring awkwardly at the pink slime mare who smiled sweetly back at him. It was like his first time all over again: he had no idea what to even do with this amorphous creature and, judging by her knowing smile, she was well aware.

“Just let me take care of everything”, she said as she flowed toward him, her liquid body flowing around his and pulling him onto his back. He threw his hooves back to brace himself and felt them sink into hers with a loud wet slurp. She flowed on top and puckered her lips as she moved in for a kiss and her sudden assertiveness making him try to pull away from her, but his arms wouldn’t pull free. Her thick body held fast and briefly stretched like rubber before pulling hooves back to the ground and leaving him at her mercy. “Relax,” she said sweetly, sensing his apprehension and slowing her approach. She formed a hoof and stroked his face, making his tingling cheek blush brilliantly, and began kissing his neck. Her supple slimy lips made wet smacking sounds and sending little jolts through his body with each peck.

Big Macintosh couldn’t even hold still; she knew exactly what she was doing and he was loving every second of it. Her body flowed and slipped around his legs and body, massaging his sore muscles and seeking out all his most sensitive spots. Everywhere her silky soft slime touched tingled pleasantly and his whole body felt deliciously warm from hers. She began to murmur and moan as she explored his body, her shape beginning to jiggle and shake from the pleasure she was feeling, her muck slurping and squelching as the couple thoroughly enjoyed the experience.

Slime began to pool around his crotch and ease his legs open, and a wet dollop pushed against his pucker. He let out a cry of surprise and pleasure, and she dopily smiled up at him. Her head half-melting into the puddle of ooze on his chest and she breathlessly panted in ecstasy, “Do you… do you like it there?” she murmured, pausing between words as if she actually was breathing.

His face burned bright red and he looked away, thoroughly embarrassed by the notion. He had experimented once or twice, but he had never tried it with anypony. The thought of what it might feel like tempted him and he nodded, “B-be gentle…”

She smiled devilishly and he clenched on inpulse to no avail. Her slime easily massaged its way through his muscle, stirring gentle circles inside him and sending ripples of pleasure through his body. The strange tingling sensation of her soft body was so intense from within that he could barely even think. Without even realizing it he had begun trusting his hips as best as he could, making his rock-hard erection slap against the slime that encased him with dull wet splats.

He gasped and froze as a loud wet slurp and the tight warm grip of slime wrapping around his pecker caught his attention. The mound of slime jiggled and pulsed, making him cry out with each spike of pleasure, and it shaped into her head with just the tip of his penis poking out of her newly formed mouth. She slurped and sucked on his member as she pistoned in and out of his ass, with the rest of her body quivering and squelching against his entire body. Big Macintosh howled and cried in pure ecstasy, furiously bucking his hips in time with her relentless thrusts into him and intense suction of his cock and balls.

Sensing his imminent orgasm she pushed deeper than ever into him, pumping enough of her slime into him to push outward on his belly, and a rush of muck wrapped tightly around his flaring pecker. He exploded into her, his violent torrent of cum inflating the slime that had encased his flare like a balloon and forming a large pearl white mass in her cloudy pink body.

When she had finally milked him dry and sucked every last drop of cum from his aching balls she at last relented and began to loosen her grip on him. His hooves pulled free from her slime with a wet slurp and he buckled, too exhausted to hold his own body up. She pooled beneath him, squelching under his weight as he sank part way into her soft body and came to a rest partially submerged in her like a warm water bed. She reformed her upper body and gently rested on top of him, lovingly making eye contact as he breathed heavily in the after throws of his orgasm. He could still see the white blob of his seed deep within what would be her belly, like a blob of wax in a lava lamp, and he couldn’t help but smile with embarrassment as she lovingly stared back into his eyes.
