Just For Fun

... bodies around Justin."

"We should always show off our bodies around Justin," Emily repeated.

"If he wants to look, he can, but we're not forcing anything upon him."

Emily went white at the thought.

"We would never..."

"I know," I said comfortingly. "We would never do anything Justin didn't want."

We continued to walk until the end of the episode, not talking, just enjoying the show.

The show, and the nipple clamps we were both wearing.

"I am Justin's perfect sex toy," we chanted in unison, staring into each other's eyes, hands roaming each other's bodies.

"I am Justin's devoted servant," Emily said.

"I am Justin's sister slut," I replied.

Friends was on in the background, but we weren't watching it.

We were busy.

"I am owned," we both said. "I am a piece of property. I belong to Justin."

Emily had read somewhere that repeating a mantra several times a day was a good way to reinforce important ideas, to make the brain truly accept them on the deepest possible lesson.

We couldn't think of anything more important.

"All I am is Justin's. He owns my mind, my body, and my soul."

That was my favorite part. Emily always ran her hands across my nipples when we got to it. I liked to give her ass a firm squeeze in return.

"I will dedicate everything I am and everything I have to pleasing him, now and forever."

I tried to let my mind go blank, to let the words truly sink in, but it was hard. This was so muchfun. I couldn't ...

"Submission brings me pleasure," we both said simultaneously.

My whole body was throbbing. We only let ourselves cum once we'd finished the complete mantra - Pavlovian training. Emily believed it would further shape us to fulfill my brother's every desire.

To that end, I would have done anything.

"I am obedience. I am slavery. I am slut."

The mantra went for five minutes. We'd spent several days writing it.

"I am cunt, mouth, and ass. I exist to be filled by Justin."

Emily nodded at my words.

If we said it slowly, letting each word truly sink in, it went for ten minutes.

"I am a drooling slut. I love to be fucked. My life is dedicated to Justin."

I wanted to cry with pleasure. Every words I spoke brought me closer to perfection.

"Slavery is my purpose, and my purpose is to serve."

As she spoke, I slipped three fingers into Emily's wetness. Her eyes widened, but she didn't slow down, not even for a second.

"I am submission," we said at once. "I am pleasure. I am arousal."

We took a deep breath, and nodded at each other, prepared for the final words.

"Justin is my life."

With that, we came. With that, we moved one step closer to fulfilling our true purpose.

My eyes were glassy. My knees were weak.

But still, I obeyed.

"Tell me how it happens," Emily hissed in my ...
