*****
Stephanie and I had been friends and professional colleagues for several years. We worked just a few miles apart from each other so we often spent time together outside of our jobs as well.
Stephanie and I also loved to flirt with each other. There was a friendly sexual tension between us that was always a fun part of our close friendship. We'd play hand games, give massages, tickle each other, pinch each other's rear, or generally just touch each other whenever we got the chance. It was all fun and friendly but the undercurrent of lust was almost like a ticking time bomb waiting to go off.
Steph also loved to swim. She was always around a pool in the summer and went to the beach often. Of course, she looked fantastic in a bikini, with her small perky breasts and her tight ass. Steph also had the most gorgeous blue eyes and lovely light brown hair that went several inches below her shoulders.
There was an annual convention that we both attended regularly. Usually after the clinics everyone else left the hotel to go out drinking. Steph and I were never really interested so we often stayed at the hotel.
On the first night of the weekend event, I was unpacking in my room when I got a text on my phone from Steph.
"I'm heading to the pool. Want to join me?"
I texted back. "Ok, I'll be there as soon as I unpack."
As I began to get settled into the room another text came from Steph.
"You'd better hurry...I'm wearing my new bikini..."
Screw unpacking. I grabbed a towel and quickly put on my swimming trunks. Thankfully, I was on the ground floor so I got to the pool fast. When I arrived at the pool gate I noticed from the posted hours that the pool was already closed, and yet I heard a little bit of splashing. It was an outdoor pool surrounded by a fence and pretty far from the lobby so the area was deserted that late at night.
The gate was unlocked though so I pushed it open and walked into the pool area. I saw Stephanie in the shallow end with water just above her knees.
"Hi there," Steph smiled. She turned to the side and modeled her new bikini. "What do you think?"
Steph was wearing a black two-piece bikini with hot pink trim. Her breasts were cupped snugly into the tiny strapless bikini top which hooked in the back. The curves of her tight TIGHT ass were outlined perfectly by the small bikini bottoms that were connected at her hips by a small metal ring on each side. She looked amazing.
"Wow Steph," I replied, "that is really hot on you."
"Thanks," Steph smiled knowing that she had made my brain sweat. "Come on in."
"How did you get in?" I asked. "Its after hours."
Steph put her hands on her hips and smiled. "Its amazing what a hotel clerk will do for you for twenty dollars. We've got the pool all to ourselves."
"Sounds good to me." I said jumping into the water.
We frolicked in the pool for a little while together splashing each other, play wrestling, tickling, basically using any excuse to touch each other, when I worked my way behind her and held her wrists. Steph struggled playfully to get loose but I held her firmly. Finally she gave up and stood passively, her blue eyes locking on mine as she looked over her shoulder at me and smiled.
I stood behind her and glided my hands up and down her curves, kissing her cheek and blowing softly in her ear.
"Now now, behave," Steph teased me. "We are colleagues at a professional conference."
"File a complaint with Human Resources," I said caressing her back and hips.
"Are you sexually harassing me?" Steph asked playfully.
"Do you mind that I'm sexually harassing you?" I teased, gently running one hand over her breasts and the other over her tight rear.
Steph smiled, "Honey, you can sexually harass me any time you want."
Accepting her dare, I glided both hands down to her rear and slid them into the waistband of her swimsuit, gripping her bare ass. Stephanie arched her back and looked over her shoulder at me as I grabbed her rear firmly.
"You've got an incredible ass, Steph," I complimented her.
Stephanie smiled teasingly at me. "Would you like to spank it?"
Her response took me by surprise. "Really?" I took my arms away as she turned around to face me.
Stephanie's eyes locked on mine as she took my hands and slid them back down her curves into her swimsuit. I gripped her tight little ass again as she leaned in close and began kissing me lightly over and over. "Do me," she said softly between kisses. "Do anything you want to me."
With that Stephanie took a step back and turned around, resting her hands on her hips. Then flashing a look over her shoulder at me, Steph pushed the waistband of her bikini down over the curves of her perfect ass, her blue eyes daring me to go for it.
We locked eyes on each other as I moved to stand behind her, placing my hands on her bare shoulders and gently caressing down her arms.
"Well?" Steph blinked as she spoke softly. "Are you just a big flirt, or are you finally going to get some?"
I reached down the front of her bikini bottoms to touch her bare pussy, causing Steph to jump slightly in reflex.
"What exactly will you let me do to you?" I asked gently rubbing her pussy in small circular motions.
"Be as creative as you like," Steph sighed as I moved my hands to cup her breasts through her top. "One rule though," Steph said in her stern voice. "Nothing goes up my ass. I know you want it but I've never done that before and I'm not starting tonight."
"Okay, that's fair," I agreed moving Steph over to the area of the pool where the lane markers were.
"You promise?" Steph asked sternly.
"Yes I promise," I agreed. "Nothing up your ass...this time."
I gently took Stephanie's left wrist and placed it on top of one of the floating lane markers. Using the rope that secured the markers, I tied her wrist snugly to the buoy.
Steph's breasts rose and fell in anticipation as I took her right wrist and tied it to the buoy on the other side. She shuddered as she felt the knots tighten down on her wrists, securing her into place.
Then, moving my hands to her hips, I gently slid her bikini bottoms off of her, kissing her face lightly over and over.
"This is really turning me on," Steph sighed, almost whispering to herself as she was stripped of her only protection.
With a parting kiss I quickly reached down below the water, grabbed her ankles and pulled her legs up behind her in one quick motion.
Steph yiped at the sudden sensation of falling, but regained her balance as her bound hands kept her afloat.
Flipping her hair back, Steph looked over her shoulder at me as I took her by the ankles and spread her legs wide.
"What are you doing to me?" she flashed a smile in my direction.
Draping her ankles over each of the corresponding buoys, I began tying her feet down with the rope.
