Yes, and Rogue absorbs his powers.

Peter's newly-turned-flesh body began to spasm on top of Rogue as he came hard, pumping his load into her stuffed pussy as he was simultaniously hit by her mutant power of power absorbtion. "Aaaaaaaaaaarrggh," he yelled loudly as his body was racked with both intense pleasure and pain at the same time.

As soon as Rogue knew what was happening, she quickly pushed her teammate off of her, his still erect cock pulling out of her pussy with a loud slurp before he fell to the floor. She jumped down next to him, careful not to touch him again and saw that he had passed out from her touch. "Peter! Peter! Oh no..."

Rogue looked down at her hands and saw that her skin had had taken on the metallic sheen of Colossus's powers and then she looked down at her naked body to see that his metallic skin was not all that she had absorbed from him. His massive steel phallus was now at her groin, protruding proudly in front of her. She looked down to see that Peter's own member was now a much more average length and knew that it must have been part of his mutation as well.
