Marcus felt paralysed, shocked and unable to move as this improbable mountain of muscle swelled and flexed in front of him, the throbbing heat of his hard on like a hot pipe across his belly and chest. He watched this amazon, this granite goddess of muscle, lower arms wider than his torso and rest her hands on her waist, muscles rolling over muscles, tendons flexing and moving as she looked down at him. Slowly, like a pedator stalking her prey. She slid down and cat-like moved onto the bed again, the frame creaking again under her weight as she slowly crawled over the top of her lover and eclipsed his supine form, a body as big as an autocar supported above him on pillars of feminine steel.

He felt the bed rock as she lowered herself towards him, her bathtub-sized pecs pressing on his thighs with surprising softness despite the crackling power they seemed to radiate. The pliant pillows of her lips first caressed and then engulfed the tip of his cock, the warm embrace enough to draw a healthy spurt of warm pre-cum from his over-enhanced erection, her moans made thick and slurred under the oral assault of thick fluid. A mighty hand traced his meat to the root and began slowly shafting the straining member, the motions bringing regular clots of heady dick nectar into her waiting mouth as she looked into his eyes and drank the spendings down greedily.

Lisa could tell that something volcanic was starting in the body of her lover as she massaged and suckled at his rock hard shaft, each luscious flick of her tongue basting her mouth with more and more of his sweet, addictive emissions, the walls of her oral cavity tingling with some strange sensation. For the merest split second she paused as her eyes dropped from the sexually tortured gaze of her lover and lingered instead on his body.

All over his comparatively diminutive frame she could see blood vessels straining at his flesh, the tone of his skin changing to a darker, redder and mottled appearance especially around his neck and chest and also the flesh around the root of his maleness.

With a sigh of lust Lisa put her hands between her super muscled thighs and found the healthy throb of her clit, strong fingers finding her familiar pleasure. Her eyes widened slightly as she fondled her nub, finding it sensitive, much more so than usual, even in her arousal. Convulsively she pushed herself up one-armed and ground her fingers into her sex, her moan of sexual need sounding like the deep rumble of a lions roar in the bedroom as she busily worked her clit, exploding into a powerful orgasm just seconds later, body thrumming with power as she came explosively, a spray of her juices fired out across the room by her unnatural passion and mighty pussy. Losing concentration for a second, Lisa put her hand down quickly to steady herself and felt bare flesh under her fingers.

Quickly realising the implications of her weight bearing down on her lover, she shifted quickly and looked down at Marcus, anxious even through the haze of her lust. What she saw astounded her even further, a man now wrapped in cords of steely muscle where before there had only been a physique of a normal human. She saw he was no larger perhaps on average, but his physiology had changed immeasurably, most noticeably in the darker red colouring of his skin and the throbbing monstrosity that was now his genitals. She couldn't help but gasp at the gnarled trunk that had replaced his cock, heavily veined and with enough hydraulic pressure in it to stand vertically away from his body even lying down. The shaft was coated in the musky pre-cum that was now flowing freely from his meat and it must have been as big around again as when he had last penetrated her, several inches longer too.

As she watched, even the bruising from her errant hand disappeared and seemed to dissolve in front of her eyes. Worshipfully, she knelt and trapped his unearthly erection between her massive pecs, fixated on the dribbling font of pre-cum that the purplish head had become. Slowly, carefully, she kneaded his meat between her mountains of chest muscle, each flex powering sweet smelling cum across her lips and face, her tongue swabbing his cock head and her own smeared features as she greedily lapped at his essence. Lisa couldn't help but slurp hungrily at the strange, transformed erection of her lover, each sloppy pass of her lips sending a tingle of erotic warmth down her own body, her clit and nipples buzzing in concert with her sexually loaded thoughts.

Orgasmic shivers rocked her again, just from the contact with Marcus' warm flesh and fluids, causing her pecs to bunch into two outcrops of volcanic feminine muscle lust, their power threatening to destroy what should have been a fragile man-shaft between them. Instead, Lisa felt her body rock as her lover improbably bucked upward hard enough to nearly lift her off the bed, the iron hard tumescence of his shaft proud and unyeilding between her pectoral cleavage, resisting forces strong enough to crack ceramcrete. Straining, Marcus jerked back, only to thrust upwards mightily again, muscle fucking Lisa's chest with a wild abandon she could barely recognise from the slightly shy, worshipful figure she had seen at the bar.

Marcus felt like his body was bathing in a fire of molten muscle, the enzymic reactions and cellular processes ripping through his body like wildfire, a mingled sense of pain, pleasure and power that was unlike anything he'd ever felt, even in the bad old days or flames and killing and lust. Biological programming that had never surfaced on any mating raids, even at the heights of passion in orgies of conquest and ritualised rape back on his homeworld, coming to the fore now, remaking him in the fires of his own desire for this amazon, unreal goddess sat astride him. He felt fingers far hotter now than normal body temperature, grip swollen, vascular thigh muscles like steel cables and pull Lisa down upon him, her flexing, swollen pecs sliding up and down his shaft like a clamp of terrible power, the blood inside his prick flowing and pumping and shifting as it withstood the sexual onslaught.

Beneath her, Lisa could see the changes in her lover slowly stop, his shoulders and a wide stripe down the centre of his chest now darker in tone, ruddy in the yellow bedroom light and... faintly mottled, in an almost animal way. Taking his cockhead into her mouth once more, she sucked hard and heard a lustful groan of surprise. The combination of the powerful squeezing around his shaft and the vacuum at the head was alien to him and exquisite, his swollen testes lurching visibly in response as Lisa sucked the warm, addictive pre-cum from the source, her tongue swabbing his glans over and over again in long languid strokes. As she inhaled mouthfuls of sweet pre-cum, some of the sweet fluid dripped down from the corners of her mouth and ran down her insanely powerful body. Idly, she reached down and massaged the nectar into her proud, prominent clit and with a gasp, came harder than she had ever done, her body arcing bacward in an explosion of lust and power, her flexing muscles making her seem to bulge with even more power, her skin tight and taut under the waves of pleasure.

With a gasp, trembling from the intensity of her orgasm, Lisa fell flat on top of her man, her massive form eclipsing his and her enormous chest heaving as she caught her breath once more, tousled hair falling about his face like a dark waterfal frozen in the moment of passion, her lips seeking his warm flesh out to kiss, to taste and to eventually find his own and share her feelings with tender caresses, breathy half-kisses. She shifted slightly and moved to take some of her weight off of him, pressing herself up his body to feed him a thick, large nipple and feel it tongued and sucked and gently tugged upon by his mouth. She felt his cock slide free of it's confines between their bodies and spring rampantly erect once more, a dollop of his pre-cum splattering messily across her buttocks as her lusts fed his even further.

The slightly sticky clear fluid tracked down her massive glutes, darting down the awesome valleys of this massive striations to baste her anus and slowly, drop by drop, slide over her thick, blushing labia, in between to bathe her vulva and slowly seep inside her wet vagina. The sensation wasn't the orgasmic fireworks of moments earlier, or the passionate lovemaking they'd shared earlier, but the dangerous, excited fizzing of a lit fuse, her instincts taking over and sensually grinding her mound down her lover's steely abs, each ridge and bump making waves of pleasure that roared through her like night time surf. Soon though, her lower lips found and, in their own way, kissed the root of Marcus' cock, delivering shuddering gusts of sensation as they bathed once more in his arousal and savoured the gnarly texture of his shaft.

With one big hand Lisa pressed the cock against her crotch and slid her mound up it's length, every knotty inch of pulsing veins and unnatural tumescence working her sensitive pussy, grazing that prominent, throbbing clit and making her whole body shudder and shake with trapped lust. Soon, her pussy slid over the rim of his cock head and with a growl that sounded almost animal, she swivelled her hips with viperish speed and planted his massive glans between her labia, at the entrance to her wet, hot vagina. One hand on the bed, her chest just big enough to touch his even with her supporting arm straight she had her hips nearly two feet off of his body, torso curled up like the Platonic ideal of all stomach crunches and her legs straddling him like the pillars of gods, she rocked once and then, eyes still meeting his, slowly forced his enormous cock into her tight little pussy.
