I woke up the next morning and immediately remembered I was in Michelle's body, with a much smaller bladder.
I rolled out of bed and made my way to the toilet. As I washed my hands, I looked at my reflection in the mirror. I still got a thrill out of being in Michelle's body. I made funny faces at the mirror for a minute while the the shower began to heat. I remembered to put my long hair into a bun, since there's no point in washing it before going to the beach. I stepped into the shower and let the warm water surround me. I had just lathered myself up when I heard the shower door open. Soon I felt Michelle's strong hands reach up and begin to caress me.
"Getting tired of it yet?" I teased.
"Nope." She smiled. "Boobs are much more fun when they're not yours."
She leaned forward and kissed me as she continued to wash my back. I turned to return the favor.
"So what's my beach outfit for today?" I asked.
"It's my normal blue bikini. Nothing super scandalous. You'll like it. I'm pretty sure I'll like it too."
I reached down and gave Michelle's flaccid cock a few tugs. She responded by cupping my ass and giving it a gentle squeeze. Our lips came together one more time as we finished our shower.
I stepped out of the bathroom and saw my bikini laid out on the bed for me. After fully drying myself off, I stepped into the bottoms and pulled them up. I then slipped the halter over my head and reached behind me to tighten the straps.
"Allow me." Michelle said, coming up behind me.
Michelle gently tightened my straps.
"OK, check out your reflection."
I went to stand in front of the full length mirror in the bedroom. In the reflection stood Michelle's short body. The bikini perfectly clung to my curves and enhanced my cleavage. Even before any makeup, or doing anything with my hair, I looked hot. And yet, Michelle was right, this wasn't a scandalous swimsuit by any means. I looked over to see her standing in the doorway with a towel around her waist.
"Fuck. You're hot." Michelle muttered.
"Right back 'atcha." I winked.
Michelle removed the towel to step into a pair of black swim trunks.
"Also, there's a silver cover-up on the dresser. You probably want to wear that around the resort."
I slipped the cover-up over my head, concealing my navy bikini. Michelle slipped on a collared polo shirt. We took a few minutes to pack a beach bag, and then we put on our sandals and headed to the resort in search of breakfast.
We settled into a breakfast buffet and got our plates loaded up. I think Michelle was thrilled with how much food she could consume this week in my body, without the normal consequences. Meanwhile, I was learning to decrease my portion size. I looked up from my plate at Michelle, only to see her staring over my head at something.
"Is that... Katie Tyler over there?" She asked, confused.
I turned around in my chair, I had to stretch my neck to see.
"Where?"
"Over by the fruit stand. Green dress."
"Shit. It is. Michelle! We came here to get away from people we know! What are we going to do if Katie sees us?"
Katie is one of my wife's very best friends. I think they've been friends since seventh grade. She is the complete opposite of Michelle in pretty much every way possible. Michelle is quiet and reserved, Katie is a complete extrovert. Michelle is petite, Katie is about five foot nine. And well, as much as I love my wife's body, especially when I'm in it, most people would describe my wife as "cute". Katie, on the other hand, is a complete knock-out. Long, bright red hair, very pale skin, very bright green eyes, and the most amazing breasts ever put on a woman. Despite being significantly larger than Michelle's, they seemed unaffected by gravity. In times past, I've had to resist the urge to stare at them, especially when Michelle's around.
"Sam! She's coming this way! I think she sees us!"
Sure enough, Katie was heading straight for us.
"Well, you're the extrovert now." I hissed at Michelle.
"And you're her best friend!" Michelle hissed back.
"Katie!" I said with extra surprise as she approached our table. "What on earth are you doing down here in Mexico."
I rose from my chair just in time for Katie to wrap me in a giant hug. I felt her warm breasts press against me.
"Michelle! I am so happy to see you! Tom dragged me down here as company on a very boring business trip! If I have one more day to myself, I'm gonna scream! I thought we'd spend some time together, but he's been super involved with his work. He's got some sort of keynote speech tonight at some cybersecurity conference..."
Katie just kept talking. I phased out of conversation for a moment until I realized I was just staring at her bosom. Finally, Michelle spoke up enough to end Katie's rambling.
"Kate." She made direct eye contact before continuing. "Michelle and I took this trip somewhat last minute because we felt we needed some time together, just the two of us-"
"Aww, Sam." I interjected. "Katie's obviously very stressed out. Maybe tomorrow we can spend some time with her. What are you and Tom doing tomorrow, Katie?"
"Well, he's got one more conference in the morning, but we're both free all afternoon and evening. Sam, can you spare your wife for a bit tomorrow for some girls time? And then maybe the two of you can join the two of us for dinner?"
Michelle shot me a look.
"Sure, no problem, Kate. That sounds great."
"Oh, thank you! I tell you what. How about the two of you meet me and Tom here for breakfast tomorrow and then we can plan our day! I'll be looking forward to it!
Michelle, I'm so glad I get to hang out with you! You look so pretty!"
And so with another hug, Katie skipped away, full of her usual vigor.
I turned to Michelle.
"Why on earth did you agree to that?"
"Because you're cute when you're flustered. Also, I saw the way you were eying Kate's rack and I figured you would wanna spend more time with them. You'll do fine. Kate's gonna do all the talking anyway."
"Uh huh. And what are you gonna do tomorrow while I'm having girly time with Katie?"
"Walk around the resort unmolested in my male body."
"Fine. Whatever. You ready to head towards the beach?"
"Yup. I'm ready to get some sun."
I followed Michelle down the path towards the beach. The resort was located on a beautiful stretch of white sand beach, with clear, blue ocean water. We picked two of the lounge chairs, far away from anyone else and began unpacking our stuff.
"Do you need help with your sunscreen?" Michelle asked excitedly.
"Ha! You're a little eager, but I'll let you."
I pulled my cover-up off over my head and sat down on the edge of the lounger. Michelle squeezed some lotion from the tube and began to warm it with her hands.
"God, I can't believe how soft your skin is." Michelle muttered, mostly to herself.
She began to rub the lotion over my shoulders and neck. Her hands worked their way down, and across my chest, stopping just short of my nipples. I felt her untie my bikini straps to get better coverage. I hastily held the front up against my breasts.
"A little warning next time?" I hissed.
"Sorry. I just wanted to make sure you're covered."
"Yeah, and a peek at the girls is a nice side effect."
"You have no idea how much I'm loving this week."
"Well, I'm enjoying it too. "
I could see the outline of her dick beginning to strain against the swim trunks.
"But it seems you are a little bit more enthusiastic than I am."
"Just keep the sunscreen coming and I'll be a happy camper."
"Deal."
I laid back in the lounger and tried to relax. Michelle was now rubbing sunscreen into my legs, and I felt her fingers gently knead into my thighs. It felt nice to be touched. I knew her boner was straining to escape, and I also knew that I would need to deal with it soon.
"I'm done." She whispered.
"Thanks. We better get you in the water soon, before that erection becomes more obvious. Take off your shirt and come with me."
Michelle pulled off her shirt and I grabbed her hand and led her down to the shimmering water. The water was warm and delightful as we waded out into the waves.
Now, normally, I don't have problems walking into the surf. But then again, I'm normally almost six feet tall. In Michelle's little body, I was struggling with some of the waves. I gripped Michelle's hand even tighter.
"Ha!" Michelle laughed. "Now you know how it feels!"
Right then, a big wave came and almost knocked me over. Instinctively, Michelle pulled me in close. I found my face pressed up against her chest.
"Thanks." I said. "Here's a token of my appreciation."
I reached down under the water to give her dick a little squeeze inside her trunks. Then we played in the surf a bit more. Even in my rather modest blue bikini, I was very aware of the way my breasts jiggled. Michelle was noticing too, at least when she wasn't staring at my ass.
"Now I see why you love going to the beach with me." Michelle said finally. "I can't wait to get you out of that swimsuit."
"Oh, you'll have me naked soon enough." I laughed, as I wrapped my arms around Michelle and gave her a kiss.
"Let's head back to the beach and sit a minute." I suggested.
We walked hand-in-hand back to our chairs. I had already set out a few towels on the sand and I laid down, propping myself up on an elbow.
"Are you having fun?" I asked.
"I love the fact I don't have to wear a shirt. And I love watching the way that bikini fits you."
"Let's go for a walk."
Hand in hand, we set out down the beach. It was very warm and the sun felt great on my skin.
"Hey, look!" Michelle called out. "That looks like a little cave entrance."
"Where?"
"Look! Just around the bend there. It's hard to see."
Michelle pulled me along, as I was now a little unsure. But we did come upon the cave, which was partially hidden behind some rocks. The entrance was low to the ground. Michelle pulled out her phone and turned on the flashlight.
"See if you can squeeze in there and get some pictures."
"Taking advantage of my stature again, huh? Sure, ill do it."
"I'll hold the phone, you just squeeze in."
The cave entrance was low and narrow. I bent over, and carefully crawled through, being careful to not get sand all over myself. As soon as I crawled through the narrow opening, the cave opened up into a beautiful cavern with a small hole in the top that sunlight was beaming through. There was a pool of crystal clear water just a few feet away.
"Michelle, it's beautiful in here! You have to try and squeeze through!"
