As Jeff made it into his room, he went and sat himself infront of the Chronivac and selected his sex monster mother Gabriel. Jeff had decided to add more things to her but first he used the Chronivac to change the layout of his house a little bit. Jeff changed it so his parents room was next to his and that the wall between them was transparent only on his side, allowing him to see into his parents room without them knowing. Jeff then used the Chronivac to make his mother go into her bedroom, so he could watch her as she changed without her knowing this time.
Jeff saw his mother in her room now, he was surprised to see how different the bedroom was from before he used the Chronivac. The bedroom was covered in large spider webs and was much bigger then it was previously. Jeff then added the changes he wanted to his mother.
Target: Gabriel
Changes to occur: she will grow 8 M-cup breasts under her spider abdomen, her legs will grow longer to lift her up higher to accommodate the new breasts, she will grow 8 tentacles along her back that are controlled by Abby and Jennifer, she will get the ability to accommodate any thing in her pussy, and her pussies will have muscles that Abby and Jennifer control, that allow her to squeeze on any intruding dicks.
Before Jeff hit enter, he selected himself and his father to change their cocks into horse-cocks that reach up to their heads.
Jeff clicked enter and began to stoke his new, growing, horse-cock, as he watched his mother change.
----------------------------------------Gabriel's POV-----------------------------
Gabriel felt her body heat up once again alerting her, that she will be changing again. Gabriel, Abby, and Jennifer got wet with arousal at the feeling of their legs lengthening and the growing pressure of new breasts growing beneath them. Abby and Jennifer began to moan into Gabriel's ear and whisper in lust filled voices for her to touch their body. Gabriel began to rub her breasts, play with her nipples, and stroke her large gapping frontal pussy. 8 new breasts now hung under her and it felt good, but she realized that atleast one change hasn't happen yet. She then felt a pressure and pinching sensation on her back, and through Abby and Jennifer realize that they were growing tentacles. Abby and Jennifer were happing when the tentacles came out, as they realize they have control over them and used that to further drive themselves and Gabriel crazy with pleasure.
They came like crazy spewing their love juices all over their bedroom. It took a few minutes to recover from it. After they recovered Gabriel decide to get dress in lingerie, since they were in their bedroom. With Abby's and Jennifer's help Gabriel put on a lacy dark purple bra on her 4 frontal breasts and stockings with garter belt of the same color. After getting all her legs in the stockings, she made her way downstairs to tie up her husband and son in her webs, so she can fuck them on the ceiling.
---------------------------------Jeff's POV----------------------------------
Jeff made sure to cum away from his computer. After he recovered from cumming he saw his mother get dress in sexy lingerie and head downstairs. Jeff decided to unleash his mother on the neighborhood, to see what changes Abby and Jennifer will make to themselves. He used the Chronivac to make his mother go hunting for women to add to her mass and made sure that Abby and Jennifer only had perverted, lustfull thoughts in their minds. Jeff really wanted to see what his former mother and sister would become given the chance to make their own changes on themselves. The last thing Jeff did on the Chronivac was to make sure his former mother and sister would NEVER change their positions and level of control over their body, Gabriel would remain the dominant one.
