"I don't think I want to wait that long."  Rouge's arms stretched out and grabbed Mystique's thoat, stranggling her.  She pulled her back to where their faces were inches away from eachother.  Rouge threw  Mystique onto the ground and ripped her clothes off while restraining her.  

Rouge's own clothes shifted off, revealing her womanhood and breasts.  A penis sprouted from her vagina and she sunk it into Mystique, who climaxed instantly.  Rouge released her hands around Mystique, who was more than subdued by her body's surprise to this rape.

Rouge began to thrust repeadedly into Mystique.  Mystique's body began to change without her control.  She shifted through nearly everyone she had ever met.  Storm, Gene, even Xavier.  Even when she assumed the form of a man her vagina was still there, filled by Rouge.

Eventually her powers exhausted themselves and Rouge pulled out of Mystique, whose body was coated in sexual juices.

Rouge lifted Mystiques head to her own vagina and watched it get sucked in.  Rouge's amorphous body happily adapted to the woman as she was sucked into Rouge's body. 

In a moment Rouge was pregnant with Mystique and began to masturebate by stretching her hand into her womb and playing with Mystique.

Finally the Gods decided that Rouge had  won.  They teleported her back to her own universe...and left her baby inside her.
