(The day before Christian and Ana's first wedding anniversary)

APOV

Hmmm… Time flies. Marriage life with Christian has been wonderful but also hectic. Teddy is such a perfect child that we both feel grateful for divine power for bringing him to our life. Speaking of Teddy, Christian persuaded me to let Grace and Carrick take care of him on our wedding anniversary a week ago. I wonder what he has in store for the meaningful day. Perhaps we'll spend some much-needed quality time at Escala. Well, I guess I just have to wait and see.

Being in Christian's arms has always been my favorite place in the world. I remember that we passed out after taking care of Teddy and connecting with each other. I'm so glad that our anniversary is on Saturday, so we don't have to worry about work as much. Even though I know that whichever day of the week it is, Christian will definitely make us stay away from work. After few hours' sleep, I'm woken up by the pressure in my bladder. When I open my eyes, I'm shocked to find that I'm looking at messy brunette hair that looks freakingly familiar. I gulp, believing that I must still be dreaming. However, when I bring up a hand to rub my eyes, I find that it is much larger than mine AND it looks masculine.

"Oh my god! What the hell happened to me!?" I exclaim. The person beside me stirs, turns around and sleepily asks me, "What's wrong, Ana?"

We stare at each other for what feels like eternity, before "Ana" bolts up in bed and curses, "Why the fuck do you look so much like me? What have you done with Ana? What… Wait! Why do I sound like a woman?"

I tentatively ask, "Are you Christian?"

"Ana" puffs, "Of fucking course! I just don't know what the fuck happened!"

I calmly say, "I'm Ana."

"Ana" rolls her eyes, "What!? Are you saying that we exchange our bodies or souls or something?"

I giggle, "I can't believe this actually happened! Before we further discuss our situation, I have to go pee."

"Ana" smirks, "You surely sound like my Ana. It's so weird talking to my face and call you 'Ana.'"

I laugh, "Ditto, Mr. Grey."

As I head to the bathroom, I have the strangest feeling "downward." I glance down, surprised yet unsurprised to see that I sport a morning wood.

I call out to "Ana," "Can you help me with an unprecedented problem?"

"Ana" jumps from the bed and runs over to me, "What's wrong baby? Are you in pain?"

I laugh out loud, "Well, since I've never had a penis before, can you teach me how to pee with it? Oh, and I think I should call you 'Christina' for now. Otherwise, it makes me feel weird to call you 'Christian' to my own face. "

Christina huffs at first, but then she smiles and winks, "Whatever makes you happy. Let's solve your problem first."

We walk into the bathroom, Christina takes hold of my penis, (which sounds really weird), and tells me to aim at the toilet first, then let go. However, I gasp when she holds it because it feels…good? I shake my head and push the thought aside for now. After following her instruction, I feel relieved yet amused because the feeling is quite novel yet familiar. I just use a different kind of a body part to do the same thing I did for the past twenty-three years.

Christina chuckles all of a sudden, "Do you remember our conversation a while ago? The one when we discussed the ultimate role-play? I guess 'this' is indeed the ultimate role-play. What do you think?"

I ponder for a few seconds and grin, "Well, I guess so. So what do we do now? Do we stay inside or go outside?"

Christina smirks with a glint of mischief and wickedness in her eyes, "I think we should stay inside and do some 'experiments.'" She wiggles her eyebrows.

"What kind of experiments? Do you mean…Oh, I see. You're so dirty, Mr. Grey."

"But you love my dirty mind, Mrs. Grey."

We burst out laughing again. As the laughter dies down, the sexual tension between us intensifies like it always does when we are together. We gaze into each other's eyes before we both lean in for a hot, passionate kiss. Being the taller one for the first time, I scoop Christina in my arms and walk back to the bed, beyond satisfied with the strength I have now. As we fall into the bed, I let out a moan and—

"Ana! Ana! Wake up, baby." I hear someone calling me, so I slowly turn to the voice and then open my eyes.

"Why do you wake me up, Christian?" I irritably scold him. "I had such an interesting dream!"

"Well, I can definitely tell with the gasp and moan you made in your sleep. Care to share your dream with me?" He winks.

I grumble, "Nope. You interrupt it before things are getting interesting."

Christian raises his eyebrow, "Such temper. I guess I have to torture the answer out of you."
