Jeff walked down the stairs coming into view of the sloppy mess of a home his parents had created. Fleshy tenticals slithered and knotted about the knee high flooding of cum and Emily was just visable between the mass. Equally visable was her massive cock that had been freed from Gabriel's swollen folds. His father turned woman still ginded on his mothers other cock but the puffy labia of her engorged pussy still stroked her freed shaft with vigor. So much so that Emily let out another whail as she was forced to violently cum again!
Still laying on her back her huge dick parallel and pointed elsewhere in the living room Jeff caught a clear view of of the violent eruption of white hot jizz blasting Amy on the sofa with the force of a fire hose! The heavy flow of spunk literally lifted Amy off her seat, over the back of the sofa, smacking into the window looking out on the front yard and the continued turret caused cracks to form on the glass before shattering and launching Amy through the air and out into the yard.
Jeff, partially concerned for his sister but wanting more not to miss her transformation leaped across the furniture avoiding the corrupting fluid filling the room like a game of 'the floor is lava'.
Leaping through the broken window from an end table that previously held varius family photos he he landed in a clear patch of grass and could see his sister splayed about a puddle of steaming hot cum twenty feet from the house! If Jeff had a score card to hold up he'd have given his mother a 10!
Amy soon stood up, clutching her head and wobbling in place her stance unsure and absolutely drenched in cum.
She then grabbed at her throat and began to have a coughing fit. Jeff took a hurried step to go help her but stopped when he saw her throat buldge like a frog croking, forcing her hands apart and Jeff realized this was the start of her transformation.
From her bulging throat and out her mouth a thick shaft of meat shot out and upward, the new weight made Amy wobble in place and still gargling and gagging as the bulging horse cock jutted up five feet from her mouth! She moaned and gargled again as her throat bulged once more and an identical shaft pushed through her mouth to sit beside its twin.
The new weight toppled her to the ground, laying on her back. She flailed in place allowing Jeff to move closer and see that varius other changes were happening.
On her chest right at her cleavage a small seam had appeared and soon bloomed into a large pussy, big enough that Jeff could fist if he only reached out to it. Her breasts also changed become round and firm, losing their nipples and teardrop shape. Her arms lengthened and hands morphed into dainty cloven hoves, her legs did the same, the feet becoming delicate two prong hooves she adopted a crab walk posture her reshaped limbs wobbling until they rapidly morphed into a new stance as Jeff recognized the new body shape as that of a deer.
Continuing the change Amy's head and chest slid downward, her chest positioning behind her new rear legs and her head with its two huge cocks flopped under the legs and smacked against her back as it became the belly of the deer body and her postion seemed to settle into place the obscene buldge that had chocked her swelling into the size of a medicen ball and was now obviously the balls to the twin dicks within the sheath that Amy's head had now become!
The change didn't end there though. Amy's crotch had become the 'head' of the body and now it was reacting.
As Amy's original pussy sat between its front legs the clitorus peaked out upwards Jeff watched in fascination as it twitched, surging in size as big as his thumb, it grew upward and outward reaching softball sized and onward. Soon the small pink organ lost any of its previous resemblance becoming more rectangular, taller, more contours to its shape, curves and widening at its base to encompass the 'shoulders' of their deer body. Soon it was clear that the new growth was a torso, the clear outline of sholders neck and chest setting into being, from the sholders bloomed arms. Slender arms like their neck and waist, two small orbs budding on the chest to become breats. The neck grew a new head. It's slender angles rapidly taking hold and setting into the familiar likeness of Amy's face with a few exceptions.the ears were the fine oval shape of a deers and flicked about curiously. Her eyes were also that of a deers, the pupils in a rectangular bar and now wider giving her a doe eyed look(punintendeddealwithit), and as her upper body cam into shape two thick prongs sprung from her forehead rapidly growing into a massive set of elk antlers that totaled 22 points and nearly 4 feet wide across. By weight alone it should have toppled her to the ground, but she carried her new crown with ease.
The body had finished its chane but finer points continued. Her new upper body was hairless but that soon changed a fine strawberry pink colored fuzz covered her hair shaping into a tomboyish pixie cut and littered with fine white dots like those of a phon. The same pink fuzz became fur acros her deer body. The fuz also sprung up around her forarms like gloves and under her arms as well as a cute little tuft that sat above her forward vagina. Amy's original head still human and tucked between her legs remained unchanged, aside from her mouth premonitory projecting the two massive cocks which projected past her front legs by at least a foot. Her expression was bewilderment at best, and agonizing tention from her new sensitive male organs that pulsed feverishly with need.
Jeff reached out instinctively towards the deer-taur's upper body and it backed away a few steps with all the apprehension and tumidness of an actual deer. It seemed this transformed sister of his my not be the same one that sat tucked below it. But a few shaky steps of its nimble legs braught her closer and she leaned down to lick at his offered hand in a very animal manor. As soon as she made contact she shivered and let out a moan that was clearly filled with exsticy and watched as Amy's twin cocks pulsed and surged in size as they erupted in orgasim. It seemed that entire upper body that had once been his sisters clit was still and incredibly sensitive sexual organ, so much so a simple touch might trigger a sudden climax. For original Amy down below her eyes rolled in mind-numbing orgasmic bliss as her throat buldged with each spay of cum she spewed forth from her mouth cocks!
