By making use of her newly increased assets, of course!

Lust reigned over you, ruling your mind and body and guiding your movements before you even knew you meant to make them. Which was why you were only barely cognizant of sliding yourself out of the warm, muddy flesh of the golem and crawling over her in the direction of those massive breasts she was now in possession of. They had already been enticing before their sudden growth, but, now, they were all but irresistible. And, given the situation, you definitely weren't going to try and resist the temptation they represented.

As such, you were straddling the mud woman's still relatively slender waist within moments, your rigid manhood jutting forward before you, dripping with mud and cum onto the golem's stomach. Of course, you didn't let your cock remain free to the air for too much longer as you moved to her hefty breasts, each one now large enough that you needed both hands to manipulate only one slippery, jiggling tit. You didn't think that such a thing would make pleasuring yourself with them difficult. You didn't think of anything at all as you wrapped your arms about that soft mass of muddy flesh and pressed your manhood up against the underside of it.

You moaned out at the contact, her muddy flesh managing to retain enough firmness that it pressed your member up against your taut abs as you ground yourself against it. The mud woman gave out more gurgling moans that were joined with that high-pitched mental panting and squealing that you'd quickly become used to. It seemed she enjoyed your manual manipulations of her earthen tit-flesh, your fingers flexing and squeezing at her breast as you continued to slide yourself against it, the underside of your shaft gliding against her moist muddy skin easily enough as her own jiggling, moist earthen flesh acted as lubricant.

You felt like you could probably cum again just from that humping against the bloated breast, but your lust demanded more to be satisfied and so, without thinking too much about it (or at all, really), you drew your hips back until the head of your member was pressing against the bottom of her massive tit. You pressed yourself against the membranous, muddy skin there once, twice...and then, on the third time, you were not pressing against, but into as you penetrated her breast as though it was a sexual orifice for you to use. Obviously, this was something that you could not do with a different sexual partner, but the permeable nature of the mud golem's flesh made this action possible...and pleasurable as the quality of the mud here was different from that between her thighs, seeming softer and more pliant, but also warmer and more receptive to your movements as your thrusting inward caused the mud of her body to shift and jiggle around your invading prick in oh so pleasant ways.

And that pleasure was not yours alone, it seemed, as the mud woman, again, arched up towards you and her hands slapped against the ground in reaction to your unexpected penetration. <Huaaa! Wh-wh-what!? What is...you c-can't...ah, ahhhn...put that...oh, ooooh....there! Ah, b-but...but it feels...g-gooood. Ungh...th-that shouldn't...feel...sooo...goooooood!>, the mental voice cried out in your mind before lapsing into only moans and panting as you began to well and truly fuck the soft, jiggly flesh of her breast. You slammed your cock into the yielding flesh over and over, feeling her tit-flesh jiggle and bounce against and around you as you drove yourself into it. Your pelvis and abdomen slapped against the bountiful tit with each penetration, sending ripples through the soft bosom and the entirety of the mud golem's feminine form as you fucked her in a way she had not expected.

It was perhaps that surprise that had her reaching another intense climax, her form roiling and undulating against you as her high pitched mental voice cried out wordlessly and a burbling bubble popped with a moan from the featureless face of the mud woman. It seemed like a series of small waves that moved through her very flesh, which was indescribably pleasurable when felt around your thrusting member. Her full body orgasmic shivers sent sensations through your body like electric shocks and you couldn't help as you clutched her breast tight, the pointed fingertips of the gauntlet sliding into her porous flesh as you did, and then came once again.

As you released for the second time, she seemed to respond with another small orgasm and, even more noticeably, more swelling of her body. This time, though, it seemed as though only the breast you'd poured your semen into grew, drawing in your seed and bloating to impossible proportions and forcing her to roll over onto her side as the weight of it pulled her over. This movement caused you to slip free of her breast with a squishing noise, making you shiver as cold air touched your manhood once more. Which only served to motivate you to sink your still achingly hard member into warmth once more.

So you shifted again, moving further up her body to straddle her head and grasp it tightly. You turned her head towards you and, without a moment's hesitation, you aimed your cock at the burbling bubbles where her mouth would have been. Your desire riding you hard, you did not even give the mud woman a moment to register what was happening before you had driven your member into the muddy expanse where her mouth would be on her featureless face. As you penetrated, you moaned outloud as there was a sensation of suction around your shaft. It seemed, mouth or not, the mud golem drew in air through this porous expanse of muddy skin. Which explained the reason why this was where the bubbles came from when it moaned, which it did right then, causing the mud to bubble and froth around your cock as you thrust it into her "mouth".

This obstruction didn't seem to stop her mental voice from sounding out, though it only cried out in pleasure at the new penetration. You, meanwhile, gruntedand moaned out in ecstasy as you slammed your prick into her face again and again, leaving an imprint of your pelvis and testicles on the featureless surface everytime your body slapped wetly against it. The mud woman's form, misshapen and bloated from your climaxes, seemed to shudder and wiggle even more than before. If you were more focused, you might realize that it looked like the muddy flesh was losing cohesion, becoming looser and more liquid than earth at times, but, of course, all you were focusing on was the thrusting of your throbbing manhood into the warm, muddy flesh as hard and deep as possible.

You didn't even stop as, after you came once more and the mud woman followed suit, her body bloated around the midsection and she ended up flipping over onto her stomach from the weight. No, you simply kept thrusting, losing all semblance of sense as you lost yourself completely to lust. You didn't care where you planted your dick anymore, driving it into the mud woman from all angles, her muddy flesh accepting your penetrations with a slick sucking sound and splatters of wet earth staining the ground and your body. The mental voice seemed to have less and less coherence as well, now relegated to pants and moans and cries that only spoke of overwhelming physical pleasure and little else.

You lost count of how much you came and lost track of where you had penetrated the now bloated mud woman from as every hole from your penetrations closed up as soon as you pulled out, usually with a dribbling of your cum along with it. You finally came to your senses as you were thrusting into the mud golem from behind, her now heavy buttocks slapping against your midsection as you drove yourself between them relentlessly. You came to your senses just as you came one last time, crying out with a hoarse voice as you filled the mud woman once more. Filled her beyond her capacity, it seemed, as, with a final mental scream of ecstasy that signaled another of countless orgasms for her, the mud woman's form finally lost complete cohesion and seemed to pop, mud streaked with your semen bursting outwards and then melting to the ground in a messy puddle of sexual fluids and wet earth.

And, in the center of that puddle, something laid just as the mud golem had before...
