With a few adjustments Alex had turned his desperately horny dickless brother into a human suit. His glass sculpture body grew opaque and soft and he regarded mobility. Tony actually looked back to normal. Except that he still didn't have a dick.
"Ah! Oh god! Let me cum already! Let me pee!" he pleaded. Alex loved the longing in his little brother's voice.
"No. It's much more fun when you're like this," Alex said.
"Fuck you! You don't know what it's like!" Tony yelled and tried to grab for the computer, but Alex grabbed him first.
"Then why don't I find out?" Through touch Alex could feel that Tony was indeed hollow inside. He was so light that pulling him back was as easy as picking up a t-shirt. There was a nearly invisible slit running down Tony's spine.
"What are you doing!?" Tony demanded as Alex stripped naked as well and slid a foot inside the opening in Tony's back. "Stop it! That feels weird..." The last words came out as almost a moan, as if it felt good to be filled.
Alex got both legs inside and pulled Tony on like a pair of pants. His feet, though larger than Tony's feet, did not streach or warp Tony's feet as he filled him to his toes. Tony didn't feel like a suit. He felt like a second skin.
Next, Alex pulled on the arms. Tony was helpless to stop his big brother. Alex's large cock was forced between his legs, since Tony didn't have a dick. Yet there was no bulge on the outside. All that was left was the head.
"No! Don't wear m..." Tony began to cry out, but was stopped as Alex's head slid up his throat and filled his entire head, looking out of his eyes. Tasting with his tongue. Feeling with his skin.
Alex looked at himself in the mirror. All he saw was Tony. The younger, slim, smooth, short body should not have been able to contain all of Alex, but it fit perfectly somehow. He tried speaking and even his voice sounded like Tony.
Deep down, like a sixth sense, Alex could feel what Tony felt. How much he had to pee. How badly he wanted to jurk off his non existent dick. How strange and invading, yet satisfying and pleasurable it felt to be worn and controlled.
