Jeff's eyes fell on his brother Callum in the picture, who seemed to have the most extreme changes out of the entire family. Jeff smirked as he saw that his brother was completely naked and he took in his brother's changes. Cal's face was still recognizably him, albeit with a third eye between his regular two and a second mouth right below his original. His torso was bare, showing a stacked pair of pecs. While his top arms were the same as they had been - wrapped around his parents's shoulders since he was the tallest - the bottom pair were flesh-colored tentacles from the shoulder down which were wrapped around his siblings' shoulders.
Callum's torso seemed mostly normal, though Jeff gasped when he saw/remembered his brother's bellybutton, which was now a vagina. Jeff almost would have forgotten about it if he hadn't been staring so intently at his brother in the photo. Callum's lower body was still human, but Jeff could see that he had three legs arranged equilaterally around his torso.
Jeff's four eyes looked down Callum's body, seeing that his brother's front crotch was bare, exposing a vertical pair of lips that looked exactly like the ones on his head. However, there was the tip of a tentacle poking out from this mouth with a sucker on the end of it on Callum's left leg. Jeff remembered that Cal had two identical mouths between the rest of his legs, and as he stared at the picture he also remembered that Cal had an anus located between his three legs exactly in the center, from which a two-foot-long cock could emerge when his brother was aroused. Jeff finished looking down the picture and noticed that Cal's feet were all bare, showing off a bizarre nine-toed foot that looked like a right and left foot merged in the center by the large toe.
"I need that," Jeff gasped to himself as he beheld his augmented brother's photograph. He put the photo down and ran out of his bedroom, intent on finding and enthralling his brother.
