She didn't even have a choice.

"Tali, I'm not sure about this..." Shepard began, looking up at the hulking, brutish robot.

"Oh? Then why are you playing with yourself, Shepard?" Tali said with a smirk.

"Wha- what?" Shepard stammered, looking down. As if possessed by some unknown ****, Shepard's left hand had found her crotch, and was currently stroking her brand new pussy with a couple fingers.

"So, it turns out an hour was a little too long for a couple of cosmetic mods." Tali informed the AI. "I had time to create a little software to make you more agreeable."

"You quarian bitch!" Shepard gasped, her fingers not ceasing from their assigned task.

"Come now, Shepard." Tali purred, embracing the platform from behind. "I promise I won't make you do anything too questionable... Commander." The devious machinist uttered the last word with such delicious irony.

"Now, approach the geth. I want you to integrate with your new friend. By way of your mouth and his cock." Tali commands.

Her actions not her own, Shepard strode over to the looming robot, and lowered herself. Taking the thing's thick red cock in hand, she obediently complied with her directive.

"He seems to like you, Shepard." Tali laughed. "Chatika, fuck Shepard's face!"

Making a few agreeable clicks, the Prime seized the sides of Shepard's head and pulled her face deeper and deeper down his shaft.

Shepard's programming burned with simulated pain and humiliation. So this is what she had erased EDI for? To be brutally mouthfucked by Tali's old combat drone?

"Good boy!" Tali urged her drone on as he efficiently pumped in and out of the infiltration platform's throat.

Tali, still partially dressed, stroked her purple pussy as she watched the former Spectre's degradation.

"Having fun, Shepard?" Tali asked, stooping down next to Shepard, bringing her masked face to eye-level with the abused gynoid.

"Fuck you, Tali!" Shepard said, spitting a mix of her and Chatika's simulated bodily fluids up onto Tali's visor.
