Reluctantly tells the truth.

"Shepard what is this?! Why are you naked?!"

Shepard knew she did not have a good excuse so she decided to be honest with her friend. "Liara set this up. She discovered a specific fetish I...Was reading about and she decided to make it a reality."

Tali had no idea what to say to that.

"Holy shit! Shepard?!"

Shepard winced when Jack and the others came over. She was now surrounded by her clothed friends while she was naked and handcuffed. Worse her ass was still an angry red. "Hey..."

"I knew it." Miranda shook her head. "I rebuilt you enough to know what your ass looks like."

Shepard blushed deeper. "Look this is..."

"Shepard what the hell is going on?" Ashely spoke. "You're naked and running around! What do you have some sort of exhibitionism fetish going?"

Shepard seemed to blush more.

"Holy shit you do!" Jack started laughing. "This is to good! We've been chasing the Savior of the Galaxy around while she gets off!"

"Jack!" Shepard groaned. It was so embarrassing to hear it put so plainly.

"I am still having a hard time understanding humans." Tali finally spoke.

"Hey who spanked your ass and cuffed you? Wait it was Aria right?! We saw where you came out of the tunnel." Jack was almost rolling on the ground.

"Yes..." Shepard said meekly. "Look you guys caught me so how about you help me with the cuffs and we all go back to my place for a drink where we can all laugh about this?" she asked with some hope.

All the girls looked at each other. Then they all gave her a very uneasy smile. Predator like grin.

"Girls?"
