Scientific perversity beget the making of a product that held such mind and body contorting properties that what Mike discovered began to formulate radical and permanent changes to his body. After just a couple of sessions with Pete doing the needed deed, evacuating a built up volume of equine semen in changing testicles, his due came from a sordid infecting of his bodily system with form changing properties.
What begins from a perversion never gets any better for those who would partake of it. As such, Rachel too, she finding her lover Mike as so endowed it filled her, granting a higher arousal and desire. She enjoyed Mike and found her sensuality passions increasing ten fold. Her lusting desires turned to letting a changing Pete do her and letting Mike have her too, the two as near stallion forms had volumes of tainted semen to spew.
Times added to their enjoyment of crude delights, bestial intent of one to the other, their sensuality doing to each an added amount of conformity to becoming as animals; just what that weird scientific mind that dreamed up the drink had as a goal.
Mike had changed too far into becoming of the Equinic shape, his aroused state made Rachel drool some, her lusty lower lips weeping as well, but with one hand stroke of the black shaft, what bloomed was a gland head so huge, it made Rachel think of a toilet plunger.
“Golly Moses, that thing is too big for the likes of me, buddy boy, you got it in me, and the thing would tear me apart!” Rachel muttered, she liked the look of it, wished Mike had drank a pony formula and not the super stud athlete drink.
Mike began first to regain some sense of conciseness, he letting out a most seductive sounding groan, his flaccidly erect shaft jerking to a full at the ready erect state.
Slowly Mike moved, crawling to push his animalistic enhanced body up with arms that looked as and would serve him well as forelegs. A wagging shake of that fully equine horse head sent strings of saliva flying, some of it splattered across the face of Rachel. Taking a deep inhaled breath, the air seemed to help revive him, his mind becoming alert as to the presence of Rachel; her vaginal juices a dead give-a-way to some male with the nostrils and nasal ability as had Mike.
A barely human groan of a “Huh,” as he consciously realized and recognized that Rachel knelt there by him, his bigger horse like eyes training up at Rachel, he tried as hard as might a true horse to greet her with a toothy horse grin.
“Really,” said Rachel, she admired her boyfriend stud, but at that’ moment felt his days as her lover Mike was a past fling. She watched as Mike strained to stand upright, and doing so, his still erect shaft flailed in the air there between stud and his supposed lover. Enlarged and flared glands still held the thoughts of how it might feel in the mind of Rachel. She forgetting the place where she knelt, she being nearer to Pete, she felt the want to engulf the thing with her mouth.
The licking of a tongue across dry anxious lips did more than slick her mouth ready for some oral pleasure, unbeknown to Rachel, her lick ingested some of the saliva that splattered across her face.
Tainted bodily fluids helped to spread the viral infectious life changing serum as had Pete discovered from his cock-sucking thrill on a brother becoming more like an equine animal.
Rachel would soon partake of some morphing person’s Equinic semen, and added to the tainted saliva, her fate would become an equal to that of Mike. Neither understood the whole of the properties affecting their lives, their bodies, and as much, the sexual drives in each.
Mike saw the lusty expression of she who he felt was still his girlfriend, if sadly she were fully human and not at all as something equine. That dumb big toothy grin and his hefting up the wagging horse cock to stand protruded at Rachel, it near to her mouth, be as much stood wanting of her to partake as had Pete. All care and consideration of the welfare of Rachael ceased in the thought process of Mike, he wanted what felt good, and could care less as what it did to anyone, as he once loved.
Rachel felt a surge of passion, her heart racing, but not from love for Mike, as much it raced due to the reformatting serum pumping through her vein, infecting and asserting her mind to want for bestiality and whatever be sensual.
As a wide open mouth and nimble fingers worked and pushed at, poking in her mouth the flared head of the horse cock belonged there on Mike; Pete stirred awake, and looking up saw Rachel about to enjoy some oral sexual pleasure with his stud brother.
