The sisters, their identical faces flushed with desire, slip into the cockpit of their Gundam, their bodies mere centimeters apart. They power up the mech, the hum of the engines a symphony of their arousal. Their hands, gloved in the Gundam's controls, mimic the movements of their desires, their fingers interlocking, their bodies writhing in sync. They lose themselves in the sensation, their twin moans filling the cockpit as they reach their peak, their bodies convulsing in unison, their love for Gundam transcending into a taboo, orgiastic dance.
