Jeff step out of his room and sees Janice in the hallway staring at her phone. Jeff sees a lewd smile cross her face and he realizes that since he has seen her she can now use the Chronivac. Jeff witnesses her use the Chronivac to strip herself naked, and turn herself into a muscular Amazonian Herm. Jeff saw her C-cup breasts enlarge to DD-cups and her new cock swelled to be 3 feet long and have the thickness of a soda can. Jeff stood there memorized by his sister's transformation and waited to see what else she would do.
Jeff saw her then begin rapidly messing with the Chronivac. Jeff saw their neighbor Gabriel appear in-between him and Janice, naked, revealing his average cock and average body. He then saw Janice's 4 friends appear naked, on either side of Gabriel. He saw Emily and Lily move behind Gabriel and stuff their heads into his ass, then Jenny and Kelly pressed the bodies against Gabriel's arms. Jeff saw as the five of them merge, Emily and Lily turning into Gabriel's new lower body and Jenny and Kelly adding themselves to Gabriel's upper-half.
He then witness in quick succession: Jenny and Kelly, their heads on either side of Gabriel began to kiss him and use their arms to molest their changing body. Gabriel's upper torso extended to allow for ten breasts to pop into life, the tits grew in till they where F-cups. Gabriel grew a pair of arms for each pair of breasts and two extra pairs, giving him? her? 12 arms in total. Gabriel's cock and balls disappeared into a new pussy.
On Gabriel's lower-half from either side of her thick hips came out long green scaled necks, that ended in dragon heads. The new heads belonged to Emily and Lily, who clearly loved their new form. Lily and Emily quickly moved their heads to allow them to eat out the frontal pussy. The five heads moaned at this and two arms reached to grab Lily and Emily's heads to hold them there. 14 H-cup tits then appeared on the lower-half.
Jeff couldn't see what happen to Gabriel's rear but he could tell the pussies of Emily and Lily like the rest of their body merged into one. Gabriel's lower-half quickly turned into that of a sexy, curvy, green scaled dragoness. Gabriel's upper half turned into that of a sexy, curvy Alraune. Her green skinned breasts got covered by red petals.
From Jeff's view Gabriel was now a very sexy hybrid, designed to be any, very horny mans wet dream.
