The next night Emma dresses up like Sophia!

The next evening, as you're preparing yourself for bed, which recently has been a prolonged sexual exploit of some kind, Emma walks out of the bathroom wearing a wig that you realize matches Sophia's hear. You also recognize the dress as one of Sophia's favorites.

You get almost instantly hard when you realize the implication.

"Hi, John", she says to you.

"Hi Sophia," you say to your girlfriend. "I'm so glad you are here tonight."

"Oh, John, there's no place I'd rather be. I'm so glad Emma is out of town so we can have some fun," "Sophia" tells you.

You embrace and make out and your hands wander over each other's bodies.

As you are zipping off the dress you whisper, "The dress is a nice touch."

Emma, also breaking character, whispers back, "That's not all I borrowed," and slides the dress off, revealing that she wasn't wearing a bra, but she was wearing a pair of panties you'd never seen before.

You could barely believe that Emma would go so far as to steal her best friend's panties to roleplay with you. It really shows how committed she is to pleasing you!
