Erica decided that she would first try her powers on her younger brother Luke.As she stood straight up to wal however she hit her head on the ceiling not realizing that she was now a giant.Her soon to be former home even had a peaked roof that was fifteen feet high and she must have been at least eighteen,that's about eight feet higher than Tania!As she went to her bedroom mirror she noticed much more than just height.She had developed an "hourglass figure" as her junior high friends would say.Her breasts were immense and took most of her upper body unable to be measured in Earth cup sizes.Her long tendrils reached down from her head to her waist and that's when she noticed her huge hips that swayed voluptuously back and forth as wide as her breasts.Then she noticed what her new curvaceous giant body had done to her pajamas that was a leopard print onesie.Her breasts had a small triangle over each nipple with string attaching on the back.Not even able to cover the areolas which were several inches in diameter.Her bottom half was a print thong that contained a massive bulge in the crotch that touched the floor!Erica could feel this as a large opposable tentacle used for her "change powers."It was around 15' long and 3' wide and very sensitive and a huge sack of goo hung where her scrotum was.With new horomones came changes of the mind as she felt the NEED to change others with her huge tentacle.Starting with her soon to be much larger but still little brother; with these thoughts she tore off her "thong" setting her monster free to sneak across the hall as she could no longer fit through a door.It slithered across the hall where the young boy was snoring with his mouth open.What Erica didn't know was that this would be ten times the strength of an orgasm and she had never had one.Even further was that when a goddess changes someone else she will grow and change further along the mighty Hemraph line with more tendrils and bigger "endowments" matched with growing lust.
