Serena Learns a Secret

When he rolled up onto his elbow to face me, I laid my head back onto the carpet, and he leaned over me and kissed me deeply. I breathed into his mouth as our tongues welcomed and explored each other.

"Are you guys hiring around here?" I asked when he laid back down next to me.

"I wish." He laughed.

After laying together in the dark for several minutes, feeling our bodies calm and our pulses go down, we helped each other get dressed, and he led the way back out of the conference room and to the elevator.

We didn't speak as we waited, but our eyes met several times and we'd trade embarrassed little smiles back and forth.

When we were sealed behind the elevator doors, I stepped to him and kissed him one last time, then wiped my lipstick from his lips just before the doors opened and we walked together as two plutonic, innocent co-workers with an entirely appropriate working relationship, through the lobby, waved to the security guard, and went out onto the sidewalk.

"Want to get a drink or something?" I asked, and I couldn't believe myself. Only an hour ago I'd been panicking about riding an Uber through town as Serena, now I was willing to go and sit in public at a local bar? Honestly, I just didn't want the night to be over.

"I'm actually really exhausted." He said apologetically. "Between working all day, and...other stuff, I feel like if I have one drink I'll fall asleep on the spot."

"So," I crossed my arms in feigned annoyance. "This was just an office booty call?"

"I'm sorry," he said pleadingly, and I immediately felt bad for teasing.

"It's okay," I smiled. "I was just fucking with you. Of course I want you to get your rest. You'll need it for next time."

"I already can't wait." He said.

He ordered an Uber and we rode together in silence, but holding hands across the back seat until the driver dropped me off at my apartment before continuing onward to his.

"Good night." We said together as we stole one last look at each other and I got out.

I'd checked my phone several times on the ride home, and I had no message from Chelsea telling me that she was coming back to the apartment. So I decided it was safe to return home as I'd left, as Serena.

Once inside, I planned on undressing and showering immediately, but I still felt so electric. I laid down on the bedroom floor in the dark and closed my eyes. I pictured the night with Zach over again against my eyelids. I felt my skin tingle as I thought of the ways he touched me and licked me. My cock stiffened as I vividly recalled the taste of his cock, and the way it felt inside me. I could feel his cum, oozing from my hole.

I could have easily fallen asleep like that, but it's a good thing I didn't, because eventually I heard the apartment door unlock and swing open.

I shot back up onto my feet and listened as I heard two voices, Chelsea's and Sarah's, come into our kitchen.

"I just could not sit there staring at each other in that library anymore." Chelsea said as they came in and shut the door.

"I thought you liked staring at me." Sarah said, then, "You got anything to drink?"

I stayed completely still as I heard Chelsea open the fridge and then pop open two bottles of beer.

I listened to them talk for a bit, about their studying, about some biological concept they didn't understand but needed to know. Eventually, I assumed they were going to stay in the kitchen, possibly studying at the kitchen table. I used this opportunity to tip-toe to the closet and slowly, quietly shut myself inside. Once in, I took off my stilettos and my blouse, then my skirt, and tucked them behind a box to put away in the trunk when I had more freedom to do so.

I had just unclasped my bra when the light in the bedroom came on. I peered through the crack I'd left open in the closet door as Sarah walked into our bedroom sipping a beer.

"What are you doing?" Chelsea asked when she followed her in.

"Let's study in here." Sarah suggested. The way she said it was odd, but not as odd as the look Chelsea gave her in reply. It was almost as if...were they flirting?

"Come on," Sarah said. "We've been sitting in chairs all day, let's get more comfortable."

"Okay," Chelsea said. "But we need to focus on this stuff."

"Of course." Sarah said with a nod.

I followed through the crack as they both walked out of the bedroom to the kitchen. A second later, my phone dinged in my hand and I rushed to silence it. I looked down at the screen...

'Going to be studying at our place.' Chelsea had text me. 'Text me before you come home.'

"Did you hear something?" Chelsea's voice came from the kitchen.

"Hear what?" Sarah said.

"Huh." Chelsea said with a pause. "Never mind."

I hurried to shut my phone off completely, and mere seconds after it went black, the girls cam back into the bedroom with their book bags, and splayed their textbooks and notebooks open on our bed.

They both got onto the bed, Sarah sitting back against our headboard, and Chelsea laying nearby, facing her, on her stomach.

"Okay, where were we?" Chelsea said, flipping through her notebook. "Oh, right, cardiovascular."

"Yes, let's get the blood pumping." Sarah said with a wry smile.

"Focus." Chelsea said, and slapped Sarah on the leg.

"I'm trying." Sarah said and flipped through the text book open in her lap. "But it's so hot in here, don't you think?"

Sarah unbuttoned the top two buttons of her shirt and fanned herself.

"I turned on the ceiling fan." Chelsea said.

I watched as Chelsea's eyes were caught looking at Sarah. It was a look I recognized, but hadn't seen in a long time on my girlfriend's face, as her mouth hung slightly open and her eyes widened on Sarah's fingers, following their every move as she lightly traced the skin of her own chest, just above her now exposed cleavage.

'What the hell?' I wondered, as I watched from the darkness of the closet.

"Would you be okay if took this off?" Sarah asked.

Without waiting for a response, she unbuttoned the rest of her shirt and slipped it off, then sat back against the headboard wearing only a plain, beige bra. I'd never really noticed how impressive Sarah's tits were. The bra was not particularly sexy -- more function than fashion -- but her full, voluptuous breasts swelled up over the top of it.

As I took in the sight of her meaty tits, and the tight cleft created between them by the restrictive bra, I suddenly felt jealous of her. But what, exactly, was convoluted. Partially, I was jealous that she had such glorious breasts for Zach to play with. I pictured him touching them, licking them, sliding his cock between them. I looked down at my own non-existent tits in my black lace bra.

But also, I was jealous of the way my girlfriend seemed so lustfully enrapt by them. She was turning beet red in the face, but kept her eyes on her study partner.

"You look like you're getting over heated as well." Sarah said.

"Sarah," Chelsea pleaded weakly. "Come on, our anatomy exam is next week. We need to know this stuff."

"Relax." Sarah said. "Studying won't do you any good if you're this stressed out."

"You're stressing me out!" Chelsea laughed in exasperation.

"Am I making you stressed, or excited?" Sarah smiled.

"Both." Chelsea pouted. "Stressfully excited."

"Well," Sarah said and rose up onto her knees. "I can help that."

"No, come on." Chelsea protested as Sarah lifted one of her legs over my girlfriend and set down on her ass, straddling her backside.

"That's what I'm trying to do." Sarah teased. "Besides, what better way to learn anatomy than with hands on experience?"

Sarah reached down and gathered Chelsea's blonde hair off her back and laid it down to the side of her head. She then placed both her hands on my girlfriend's shoulders and began to gently knead at them through her t-shirt.

"Ughhhhnnnmmmmm." Chelsea let out a sound that began as a frustrated sigh and ended as a pleased moan.

"There you go, let that stress out." Sarah said softly as she leaned over Chelsea's back to apply more pressure, her breasts hanging heavily against the restraint of her bra. She slid her hands down Chelsea's back and up under her t-shirt onto the bare skin of her back.

"Damn you." Chelsea said into the mattress. "You always know how to touch me just right."

I couldn't believe my eyes and ears. I stood there, frozen in the closet, my entire body numb from the shock of watching my girlfriend be seduced by her friend and med school classmate. Zach's girlfriend. Further more, it was becoming very clear that this was not the first time. How long had this been going on? It explained their sudden insistence of studying in the privacy of the apartment together. Did Zach know?

"You're too restricted." Sarah said, softly, as she slid Chelsea's t-shirt up her back. "Let's get this off."

Chelsea rose up onto her elbows to allow Sarah to lift the shirt over her shoulders, over her head, and off her arms, tossing it to the floor just outside the closet I hid inside of.

"This too." Sarah said and unsnapped Chelsea's bra.

Chelsea wordlessly pulled her bra straps down off her shoulders and slid her bra out from underneath her, then laid down on her petite, bare breasts against our bed.

"Not fair." Chelsea said with a devious smile and looked back at Sarah.

Sarah nodded and reached to her shoulders to slide her bra straps down her arms one at a time. As the tension was released, her breasts weighed heavily down into her bra cups. Reaching around behind her, she unsnapped her bra, releasing her natural, heavy breasts to settle into a slight sag on her chest. Her nipples large and pink.

I watched Chelsea watch this over her shoulder. Who was this person who drooled lasciviously over another woman's body? Who was my girlfriend? The irony hit me pretty quickly, of me having my secret alternate life and meanwhile Chelsea did as well.

As I watched Sarah lean over my topless girlfriend, her breasts hanging down and swaying as she worked her hands slowly and sensually over Chelsea's skin, I listened to the soft moans my girlfriend let out at each passing of Sarah's hands.

It didn't occur to me until that point that I had a raging erection. I reached down to feel my little cock thrusting, rock hard, out of my panties. As I traced my fingers along my stiffness, a chill of pleasure shuttered through my body. I began to stroke myself slowly as I watched through the door crack.

Sarah worked Chelsea's back slowly, dedicatedly, then leaned down over her, her breasts falling against Chelsea's exposed back, and kissed her on the ear. She whispered something into her ear that I couldn't make out, but immediately afterwards, Chelsea lifted her hips off the mattress and reached underneath her to undo her jeans.

Sarah got up and repositioned herself at Chelsea's feet, then slid her pants off, followed by her panties, and threw them onto our bedroom floor. Sarah then stepped out of her own pants and underwear, and settled onto her knees between my girlfriend's spread legs.

A breath caught in Chelsea's throat as Sarah ran her hands up the backs of her thighs and over her ass cheeks.

As I watched them together, their naked bodies working against one another, I couldn't help but admire how well their stark physical differences complimented each other. While Sarah was curvier and pale-skinned, dark-haired, with heaving breasts, a soft stomach, and thick, full hips and ass, my girlfriend was more athletic and trim, seemingly permanently tan skin with long blonde hair (like me), with perky little a-cup breasts, a tight ass, and long slender legs.

"Feeling better now?" Sarah asked as she kneaded the insides of Chelsea's thighs, working her way from the knees, upwards.

"Mmmm." My girlfriend moaned in a way that I had not heard in forever. "Yes."

Sarah worked her hands up the insides of Chelsea's legs, and I watched as Chelsea arched her back, lifting her ass to allow her secret lover access to slide her hands between her legs, caressing her exposed, bald pussy.

"Ohhhh." Chelsea moaned as Sarah ran her touch firmly up her ass crack and back down between her legs, slipping a finger through the wet lips of her labia.

Sarah slid down onto her stomach between Chelsea's legs, and Chelsea rose her ass up -- presenting herself to Sarah much like I'd presented myself to Zach earlier -- and Sarah pressed her face into her sex. Sharp, orgasmic gasps escaped my girlfriends lips as she dug her hands tightly into the blanket and buried her face into our bed. Sarah's head worked and gyrated as she devoured Chelsea's pussy.

"Oh my god, baby." Chelsea yelped, reaching back behind her to grab Sarah by the back of the head and push her into her ass.

"Fuck," I absent-mindedly whispered as I stroked myself. I froze and watched for any sign that they heard me.

"Yes! Yes! Baby!" Chelsea screamed, agonized with pleasure as Sarah lapped up her gushing juices. Her back flexing and arching impossibly against the oncoming strain of her orgasm.

They call each other baby? I thought, as I started to touch myself again.

Sarah licked and slathered Chelsea's pussy, running her tongue through her pink gash and up into her asshole and back. Chelsea dug her fingers impossibly deep into our mattress and buried her face in our pillow as her entire body began to shutter and convulse. She yelled into the muffling pillow, cries of passion like I don't think I've ever heard from her, as she shook with what looked like an uncontrollable, carnal wave of orgasm.

Immediately after she came and caught her breath, Chelsea became an animal. She threw herself over onto her back and reached down at Sarah to rip her up to her by her arms. She grabbed her and rolled over with her, pinning Sarah on her back on our bed. Chelsea rode on top of her, gyrating her hips, mashing herself into one of Sarah's thighs, as she pulled her up by her head and kissed her passionately, forcefully, desperately.

I pumped my cock faster and harder as Chelsea dropped Sarah's head back onto the bed and took up both of her ample breasts in her hands. Sarah reached up and placed her hands on Chelsea's own breasts. Chelsea dropped to her stomach between Sarah's legs and pooled her tits together, placing her mouth on one of her large, pink nipples.

"Oh, wow." Sarah moaned as my girlfriend dedicated herself to sucking, licking, and biting each of her nipples until they were hard and erect.

Chelsea kissed each of her breasts, then worked her way with kisses down Sarah's pale stomach, to her furry mound. She placed her hand against Sarah's eager slit and slowly massaged, pressing her finger tips to her clit.

"MMmmm." Sarah clenched her eyes and bit her lip, tightly grabbing each of her own tits as Chelsea used her fingers to spread her pussy lips, and slick her tongue through her crease.

Chelsea licked her through several times, as if licking an envelope, before placing her mouth to her moist sex and devouring her. She slipped a finger into Sarah's pink hole, then another. She pumped her fingers in and out of her wetness, harder and deeper as she went.

"Yes!" Sarah yelled. "I love the way you touch me."

I love the way she touches you too, I thought, as I pumped on myself. I felt my balls tightening as I neared my own orgasm.

As Sarah neared the precipice of erupting, Chelsea got up onto her knees beside her, using one hand to work Sarah's pussy rapidly and steadily, and placing her other hand tenderly onto the side of her face as she leaned down over her and stared into her lover's eyes.

I don't know I'd ever seen Chelsea look at me that way, as if she wanted me so fully to please me. I don't know if I'd ever shared the look with anyone...except Zach.

Zach! The thought of Serena's lover flooded my mind and senses. I imagined that he were there with me, hiding in the closet, watching our girlfriends fuck each othr as he fucked me to the edge of orgasm.

"Yes! Keep going!" Sarah moaned, writhing around as she gazed up into my girlfriend's eyes. "Yes!"

Just as Sarah came, I closed my eyes and imagined Zach's glorious cock buried deep inside me, pulsing out his cum as my own shot out of me, splashing against the inside of the closet door. I had to reach out for the door jamb to keep my self on my feet.

After I'd worked out my orgasm, I looked out through the door crack again and saw Chelsea laying over Sarah, their bodies sweaty and skin flush, kissing each other tenderly with closed eyes. Their lips hungry for one another's, each of their tongues eager to feel the other.

I watched them both lay out on their backs, catching their breath as they stared up at the ceiling just like Zach and I had done earlier that night on the floor of his office conference room. I could see their hearts pounding in their chests, then start to calm, coming back down to earth.

"Well, I feel pretty well studied." Sarah quipped as she got up and kissed Chelsea one more time before gathering her clothes off our bedroom floor.

"I need to shower." Chelsea said with a giggle. "A very cold shower."

My girlfriend got up and came towards me in the closet. I tried to step back away from the door as much as I could, but breathed a sigh of relief when she grabbed her bath towel off the door hook and wrapped it around herself.

"I'd say join me, but...." Chelsea said and trailed off.

"Yea, I know." Sarah said as she finished getting dressed. "I wish, but I should get home."

Before Sarah left, they shared an embrace and a deep kiss.

"Don't get me all riled up again." Chelsea said as she broke away and pushed Sarah towards the bedroom door.

"Okay, studying tomorrow?" Sarah asked, as she threw her books into her bag.

"Of course." Chelsea said. "But we need to actually do some studying this time."

"Right. Sure. Of course." Sarah said, and with one last flirtatious look, left our bedroom and walked out of the apartment.

Chelsea stood there for a moment with some thought crossing her mind, a subtle smile on her lips, then turned and went into the bathroom and ran the water.

I waited until I could hear the water hitting her body before I emerged from my hiding place. I quickly stripped out of my nylons, garter belt, and thong, and stashed all of the clothes into Serena's trunk. I turned my phone back on and sent a text to Chelsea.

'Almost home.' I typed and sent, and Chelsea's phone chimed from our kitchen table.

"Holy shit." I exhaled as I wiped the makeup from my face in the bedroom mirror.

"Sam? Is that you?" Chelsea's voice came from the shower.

"Yea." I said, trying to sound as normal as possible. "I text you but you must have been deep into studying."

"Yea, pretty intensive session," She said. "Would you mind bringing me a washcloth?"

I fetched one from the closet and brought it into the bathroom. When I saw her standing in the shower, water and soap running down her breasts, her skin still flush from having the orgasm of her life only fifteen minutes prior, I suddenly wanted to be in there with her. I wanted to feel what we'd each felt that night, but feel it together.

"Why are you naked?" She asked when she saw me.

I hadn't even realized I didn't put any clothes on after undressing. We stood there like that, our eyes locked for a moment, then I stepped into the shower with her.

"What are you..." She started to ask but I stopped her by pressing my body against hers and feeling her post-sexual heat on my skin. My cock started to throb to life again between her wet thighs and I could feel her sticky wetness lingering on her pussy.

I looked into her eyes and kissed her hard. It was like Zach had kissed me earlier. It was like she'd kissed Sarah. She hesitated a second, caught off guard by my rare show of sexual forwardness with her, then I felt her hand softly against my face as her mouth relaxed and accepted mine. Our breath and tongues dancing together.
