She stepped up behind me and her skin was so warm against mine. Firm little nipples pressed into my back as her arms slid across my naked body. One hand found a nipple of my own and gently began to tug at the sensitive nub while the other hand reached up to touch my cheek. Her gentle caress, the warmth of her touch, the tenderness and intimacy. My lover. My sister. She pulled my body into hers and laid delicate kisses over my shoulders. I trembled. The hand at my breast began to travel downward as she bit at the back of my neck. I gasped and started to grind back against her. I leaned my head back and saw green and blue.
I woke with a shudder, my body tingling, my legs tangled in my sheets, a familiar slickness between my thighs. I stared into the quiet darkness, the only sound was the soft breathing from across the room. Rory didn’t snore but they breathed loud, even while they were awake. They were alright, as far as roommates went, especially for as short of notice as I had given. Less than four weeks before the end of the term and summer housing had been filling up fast, I was lucky my school had *anything* available. I suppose I should also count myself lucky that my parents were footing the expense. Lucky. Right. I was lucky I didn’t get completely thrown out on my ass with just the clothes on my back.
*Thank god I’d had those back on by the time they’d gotten back from the store,* I thought, rolling over to check my alarm clock. The little red numbers told me it was not a time for the sensible to be awake yet. My thoughts, however, were not so easily swayed. Flashes of my dream danced in the dark. *Carol…*
It had been two months since my mother had kicked me out of her house for, as she saw it, sexually corrupting her little girl, and in those two months I had not even received so much as a text from my little sister. No doubt our parents were being extra vigilant in keeping their precious Carolyn away from the twisted deviant monster.
*It was her idea*. I recalled the memories. Naked below her teeshirt. That first touch. Her heat. The way she came on my fingers. Those same fingers were now working their way down to my own slick lips. I brushed a finger over my clit and shivered. I did it again.
*Carol…* I could still picture the way her blue and green head looked between my thighs. The way her inexperienced yet determined tongue played at my clit. The way her fingers had fucked me.
*Oh god*. I bit my lip and fought back a moan. I didn’t want to wake up Rory by orgasming again. I fingered myself as my free hand moved to my nipples. I could practically still feel Carolyn’s hot mouth on them. I pinched the tender flesh and whimpered.
*Her mouth*. The heat. Her eager and exploring tongue. The taste that hung on her kiss.
*Those soft, sweet lips*. My fingers slipped back up and started fast, tight circles. My hips twitched. I twisted the nipple between my fingers and flicked my clit at lightning speed. The cry grew in my lungs but I closed my throat. I started to gently shake as the wave hit me. I held my breath until I could finally exhale silently again. My sister.
*What is wrong with me?* I noted the slight wet spot right at ass level with a light sigh. It would still be dark for a few more hours. I closed my eyes and tried to focus on Rory’s breathing, letting the soft rhythm encourage sleep.
The next thing I knew, sunlight was creeping through the single window in the wall between Rory’s bed and mine. A shadow was above me, bleary in my still half-asleep eyes. Pieces came together and I realized someone was leaving over my bed. Green and blue.
*Am I still dreaming?*
“Good morning,” said the figure above me.
Not dreaming. “Carol?”
Wordlessly she dipped lower and pressed her soft lips to mine. For the briefest of heartbeats I was lost in her kiss and let my tongue slip across her bottom lip. Then I came to my senses and pushed her back.
“What are you doing?” I snapped, quickly scanning the room for Rory.
“Relax, we’re alone.” Carolyn said and sat down on my mattress, “I needed to see you. I miss you.” She brushed her fingers down my cheek, then brought them to my own and laced our hands together.
I was still reeling as questions flooded my morning-fog brain, but I took a minute to relish in her touch. It was good to see her. “Mom?” I asked an entire question with a single word.
“Thinks I’m with Stephanie.”
“Carol…”
“Don’t. It’s been miserable without you. I’m treated like a prisoner, watched all the time. Mom makes her remarks. I need to get out of there.”
“Well they can’t stop you. You’re eighteen. Move out.”
Carolyn looked at me with pained eyes. I could see the question on her face. She bit her lip, waiting for an answer.
“I don’t know about—“
The door swung open and Rory walked in, their arms carrying bags of breakfast, tight dark curls bouncing around their head, and their customary wide warm smile.
“Good morning!” Rory chimed, then finally noticed Carolyn. “Oh, I’m not interrupting?”
I pulled my fingers loose from the hand I was holding and sat up stiffly. “No, no. This is.. my sister, Carol.”
Rory frowned. “Oh! Well shoot, I only grabbed two sandwiches. Here.” They held out both arms, a brown paper bag in each hand.
Carolyn stood. “No, I couldn’t. I should be leaving anyway. It was nice to meet you.” She grabbed the edge of the still-open door and paused, then turned back. “Think about it? I love you, Beth.”
“Oh, uh, love you too.” I felt a slight warmth in my cheeks that I prayed Rory wouldn’t notice. Sure, it’s not an odd thing for siblings to express affection for each other, but her tone. Carolyn said the words with intent. Then she smiled and slipped out into the hall, closing the door behind her. I took one of the bags from Rory and they took a seat on their own bed across the room.
“You two seem close.” Rory said, digging into their breakfast. “You didn’t say you had a sister.”
“She’s just my kid sister.” I kept my eyes down and focused on the egg and bacon between toasted sourdough in my hands.
“She’s cute. Makes me wish I had a sibling for that kind of relationship.”
*You have no idea*. I filled my mouth with sandwich to avoid having to comment on that one.

The engine in the slightly rusty used-to-be-yellow hatchback sputtered and died again. Sitting in the student parking lot, I cursed under my breath and lowered my forehead to rest on the steering wheel.
*Be grateful to even have a car*. Not that this weak-piss colored junker could be called a car. Dad had promised me a new one if I actually got my marine biology degree, but I had doubts that was still going to happen. I was a pariah now. Maybe my mother didn’t aggressively hate me, but there was a coldness in her tone when she told me I had to leave, making it clear that, sink or swim, I would not be welcomed back.
I turned the key again and the engine cranked so hard the little car shook but still refused to start.
“Fuck!” I beat the dashboard with futility, leaned back and closed my eyes with defeated acceptance. I guess I could walk to the library. It was only a mile and a half in the blistering sun. I sighed. Then a sudden knock on the window made me nearly wet myself.
“Hey let me in!” Carolyn said, slightly muffled through the window that could not roll down anymore. My heart still in my throat, I hit the door unlock button. When she pulled the door open I got a look at the blue paisley sundress that hugged her midsection, accentuating her curves and flowing down to her thighs. Large round sunglasses sat on the bridge of her nose, and most of her blue green hair was tied back in a short ponytail. She climbed in and closed the door.
“What are you doing here?” I asked.
“Nice to see you, too.” She glared at me despite her smile. “What are *you* doing here? Trying to roast yourself? There are easier ways to—“
“My goddamn car won’t start.” I hit the dash again, “piece of shit finally died for good.”
“Well what’s it doing?”
“Why, you gonna climb under the hood?”
Carolyn sighed and could feel her eyes rolling behind her shades. “You don’t need to be a bitch to me about it. I haven’t seen you in days and you’re immediately biting my head off?”
“You’re right. I’m sorry. I’m just… frustrated.”
She reached out a hand and rested it on my shoulder. “Just take a breath. What’s the problem?”
I sighed. “I don’t know, it just won’t start. It does this,” I turned the key and the worn out engine roared to life, albeit not very enthusiastically. My jaw dropped and Carolyn giggled.
“You beat some sense into it.” She said.
“Or you’re just my lucky charm.” I said. She smiled bashfully and her eyes sparkled. She really was beautiful. Her delicate jaw, big hazel eyes, slightly pouty mouth.
*That mouth*. I forced my eyes shut and shook my head. *Enough!* I cleared my throat and reached to crank up the car’s air conditioning. “So what are you doing here?”
“I was in the area.” Carolyn said.
I just stared at her. *Home* was on the other side of town. She would have to have taken 2 different busses or walked five miles. This was nowhere near her area.
“Okay fine. I wanted to see you again.”
“Carol…”
“I miss you! When you got your place with Amy I was devastated. I went from seeing you every day to maybe once a week. Then you moved back home and I was so happy… I don’t want to lose you again.”
“You’re not going to lose me. I’ll always be your sister.”
“You know what I mean.” She gave me those eyes again.
I sighed again. Of course I knew what she meant, and having contact suddenly cut off was hard, but I couldn’t help the feeling that I was leading her on. Letting her maintain this fantasy. Even more than that, going along with it. I knew she loved me, and I loved her too, but did I love her like that? I didn’t know. Obviously I found her attractive, and I found the idea of her being my sister and my lover erotic, but was that all I was feeling?
“I’m going to the library.” I said, changing the subject.
“Can I come?”
“You want to go to the library? You’ve read like ten books in your whole life.”
“Hey! I like books.”
I just shook my head. “Buckle up.”
The library was quiet, as it should be, and the smell of books was rich in the air. Carolyn and I had split up as soon as we walked through the doors; she was heading towards poetry and romance, myself going directly to the reference section.
I stood in the middle of the wide, comfortable aisle and scanned the titles on the tall shelves. Off the shelf just above eye-level, I plucked *Killing Our Oceans* and cracked it open. I was skimming through a section on endemism when my sister’s colorful head poked around the shelves.
“Pst!” Carolyn demanded my attention. “Pst!”
“What?” I whispered, marking my page with a finger, and beckoned her over.
Carolyn’s short dress fluttered as she came down the aisle and slid up beside me. The smile on her face promised trouble. She had her hands behind her back and began to oscillate on her ankles. Eventually it was too much to bear and she broke.
“Guess what I found?” She whispered, smiling.
I raised an eyebrow.
“Go on, guess!”
I rolled my eyes dramatically. “How am I supposed to know?”
“Just guess!” Her voice jumped up in volume.
“Shhh! Okay! Uhh, something with pictures?”
“You’re *so* funny.” She brought the book forward. The cover was black with a branch and a hanging fruit. The title read; *Coming home to her.*
“What.. is it?” I felt my nose crinkle.
“It’s poems.” Carolyn said, then looked around quickly and lowered her voice further, “About *lesbians*.”
I blinked slowly.
“I thought I might read some,” Her eyes left mine for the carpet under our feet, but soon returned. “To… you. Like. *You know*.” She wriggled her eyebrows at me.
*Oh fucking—* “Are you seriously talking about this right here?” I was struggling to maintain a whisper.
“Oh relax.” Carolyn shoved me gently with her body, “Enjoy the date.”
“What? Carol, this isn’t a date!”
Someone from a table on the other side of the tall shelves gave a stern “Shhh!”
“Carol,” I started quieter.
“No, you’re right.” She turned and slid her hands over my hips, pulling my pelvis into hers as she leaned in close. “*Now* it’s a date.”
“Don’t.” I said, but my voice quavered.
My sister’s face dipped toward my neck.
“I said don’t.“ I managed a little firmer, but when her lips made contact with my skin I stifled a moan. “Not here.”
Carolyn stopped sucking long enough to whisper “Shhhh.” then gave my ear a nip.
“Carol…”
“We’re just two girls in a library, that’s all.” She locked her mouth to my neck again and I could feel my body responding. My nipples grew rock hard, blood rushed to my clit, and my knees faltered.
*Stop this. Stop this!* But her mouth was so warm. It didn’t help that I had been having dreams about her every night since she surprised me in my bed. I was only slightly aware of my fingers brushing the bottom edge of her dress. Carolyn sucked hard and held it until I whimpered.
She pulled back far enough to look me in the eyes, and the sheer lust written across her face made me blush.
“We should go back to your dorm room.” Carolyn said, her voice smoldering.
“But…” I tried to think of an objection but my brain was not cooperating.
“I *want* you.” Carolyn started to grind her hips against mine. “Once isn’t enough.”
I squeezed my eyes shut and shook my head. “But Rory…” Finally something to grasp. I couldn’t very well fuck my sister in my dorm with Rory knowing that she’s my sister. My sister. I tried, weakly, to force space between us. She giggled softly and grabbed my ass through my jeans.
*I want you, too*. I desperately thought, but my mouth continued to protest. “This is dumb. If someone sees… Stop. We’re just gonna get all worked up and be frustrated.”
“So you’re getting worked up?” Carolyn smiled wickedly. “I’m so sorry,” She teased. “Slut.”
I think she was just as surprised as I was when my fingers touched her inner thigh. Her eyes went wide and her breath got caught in her lungs. Without me telling them to, my fingers slowly traveled up under the blue dress. I held our eye contact as I reached her velvety lips. She had no panties on, and she was *very* wet. I brushed her clit with a finger and she finally exhaled, shuddering.
With *Killing Our Oceans* still in my hand, I swept my arm around her and pulled my sister to my mouth. I sucked at her bottom lip and bit down as I slid my fingers over her clit again. She squeezed my ass in response, along with a soft sigh. It was nearly impossible to resist the urge to drop to my knees and set my tongue to work right there.
I was moving my fingers in slow circles as our tongues danced and the heat from our bodies threatened to set the library on fire. I broke the kiss and lowered my head to her shoulder, biting the soft exposed skin. Another bite, closer to her neck. Another bite. Closer still. As my face reached the crook of her neck I bit down hard and slipped my busy fingers inside her.
Carolyn squeaked and I heard the book she had been holding drop behind me. It was just enough to break the spell and I pulled myself away from her.* At least she has the decency to blush*, I thought as I turned around to pick up the book. I don’t know how I didn’t expect it, hell, I might have even done it myself, but as I bent over a hand found my ass with a loud smack and enough force to make me stagger forward.
I whipped around to glare at her and she was standing there, covering her mouth, and quietly shaking with laughter.
***
It was getting dark as I pulled around one last turn and brought the car to a stop. Six houses down was home. What used to be home, anyway. Carolyn would walk from here. I dared not get any closer with her in the car. If our parents saw me dropping her off they would know she had been lying about where she had been.
“When will I see you again?” Carolyn asked from the passenger seat.
“I don’t know. Probably shouldn’t be for a little while. Mom’s gonna think you have a thing for Stephanie and try to stamp that out, too.”
“I don’t care what she says. She can’t control me.”
“Uh. As Long as she has shit to hold over our heads, yes she can.” It suddenly occurred to me, and not for the first time, how incredibly stupid this all was. Here I was completely jeopardizing my entire future and for what, because I got off on the idea of fucking my sister? I had no doubts that, if we were caught again, I would be totally cut off.
“Well, have you thought about it?” Carolyn asked, rotating in her seat.
“Thought about what?”
“About getting a place. With me, I mean. A place *together*. I’d be really good to you.” Carolyn wrapped her fingers around my forearm and leaned in closer. Her big hazel eyes were a kaleidoscope of emotions as she searched my face. The only thing I wanted in that moment was to close the rest of the distance between us and meet her lips with mine.
*I shouldn’t. Think, damnit, for once, think!* “We can’t do that.” I said, finally. “We can’t.”
“Why not?” She said with an edge in her voice. “Do you not want to live with me? Are you happy with how things are?”
I sighed and looked away from her searing gaze. “Fuck, Carol. What did you think? We’d have a happy little normal relationship?”
“And why not? Nobody knows we’re sisters.”
“Rory knows! Oh, I’m sure they’ll have *nothing* to say when they find you in bed with me.”
“Well… maybe we’re just close?”
I stared at her with my mouth half open in stunned disbelief that we were even having this conversation. “You’re not thinking about this. You’re stuck in a fantasy. Do you want to have to hide *everything*? Do you think we’re gonna run away together? Are we gonna get married? Mom and Dad would *never* talk to us again, and you’re still dependent on them. Hell, I’m still dependent on them!”
“I’ll get a job!”
“Carol…”
“So you just wanna give up without even trying?!”
“Give up on what? There’s nothing between us!”
Tears immediately began to pool at the corners of her eyes and her lip started to tremble. “B-but you-you’re.” Carolyn’s composure was quickly melting.
“I’m your sister. We’re *sisters*, Carol. We have to stop this. It’s not healthy.”
“Who says?! Mom?! Like her and Dad are so good? Fuck that. I love you, Beth, and you love me too, don’t you?”
“I…” How was I supposed to answer that? If I said yes it would only encourage this further and throw gasoline on her fire, but if I said no it would crush her and it would be a lie. Would it, though? Of course I loved her, but did I *love* her? Sitting there watching her pretty eyes leak, I knew the answer but lacked the strength to say it. “What does it matter? What the hell would I realistically do about it, even if it was true? I don’t want a secret romance. That’s not fair to either of us, ya know? You can’t say you honestly want that? The sneaking and the lies and—“
“I don’t care! It’s better than not having you at all!” Carolyn could finally hold herself together no longer. She dissolved into shaking sobs and buried her face in her hands.
My resistance melted some and I placed my hand on her shoulder. It was too much. I didn’t have it in me to sit there and watch her heart fall to pieces. “It’s not like I’m going anywhere. You know? You’ll always have me.”
Carolyn sobbed out something I couldn’t understand.
“Hey…” I stroked her blue green head. “It’s okay. Hey, now.”
When Carolyn looked back up I could see where her tears had fallen by the mascara running down her cheeks. “Do you love me?”
“What?” I stalled.
“*Do you love me?*”
“You know I do—“
“No. Do you *love* me? Do you want to be with me?” Carolyn’s eyes were still full of tears, but they’d grown hard. She wouldn’t yield the question.
“That’s not fair.”
“How is it not fair? It’s a simple question with a yes or no answer.”
“Because if I say ‘no’ it’ll hurt you..”
“So it’s ‘no’?”
“..but if I say ‘yes’ it’ll just cause problems.”
Carolyn stared at me. No, *glared* at me. Her eyes were squinty and the tremble in her lip was gone. I opened my mouth to speak but only succeeded in making a dry croak. I shrugged.
“Goddamnit, Beth, answer me!”
“Yes.” I heard myself say, though I didn’t think I had spoken.
Carolyn’s face softened and she reached out to take my hand. “Do you?” A smile sprouted in the corner of her mouth.
*What have I done?* I closed my eyes and let my head fall back onto the headrest. “Yes.” I said again, barely above a whisper. And so help me, I did. I really did.
It was very quiet after that. We sat in a comfortable silence; me questioning the life choices that had led me here, my sister trying not to let her smile tear her cheeks. Eventually I told her to go home. She promised she would see me soon then departed with a kiss. I left deep in thought, listening to the worn out engine rattle and screech as I picked my way back through town.
***
The line of people waiting for breakfast in the cafeteria was long but moving steadily. I stood next to Rory and studied the mural painted by a Rene Hawking in 2003. A caricature of the city with the ocean on one side and mountains on the other. A few noteworthy landmarks received their own specific depiction. It was cute and, even though I was quite familiar with all it had to offer, it gave me a certain comfort.
“You’ve got something…” Rory said, drawing my attention. I looked at them and they brushed at their neck.
“Huh?” I mumbled, reaching up to feel my throat. “Where?”
“Here.” Rory reached out and touched my skin. “Oh. Ohhhh! I’m dumb.” A small smile grew on their lips. “Who were they?”
“What?” I was genuinely confused.
“You’ve got a hickey on your neck.” Rory giggled.
*Carol*. I lost the battle with the blush creeping over my cheeks. “I don’t know what you mean.” I said, trying to buy more time to come up with a reason for the mark other than my little sister.
Rory laughed. “Oh come on. Don’t lie!”
“An ex. It was an ex. We, uh, had a moment.”
“Some moment.”
*Damnit Carol.* I could throttle her. I didn’t need to ask to know it had been intentional. Marking me as her own. The thought irritated me almost as much as it made my insides flutter. She had to be more careful than that. It wasn’t a secret that I was single, I complained about it often, and if I started sporting hickeys questions would follow. I was supposed to meet Olivia for lunch.
“How bad is it?” I asked, rubbing the area Rory had touched.
They smiled again. “Not that bad. I didn’t notice until just now.”
*Great.* I held my palm to my throat, wishing I had seen it earlier and done something. A little foundation, a high collar, a stylish summer scarf, something. I had to come up with an idea before lunch now, and—
“Hey, it’s just a little hickey.” Rory interrupted my spiraling thoughts.
I hadn’t realized I was scowling. “What? Oh. Yeah it’s nothing.”
When I got the chance, I grabbed a jalapeño bagel and a little package of cream cheese off the food cart and placed them on a dull green dining tray, followed by a carton of milk and a banana, then waited for Rory. The two of us sat down at a small round table. They tried to make conversation as we ate, talking about the latest news around campus, intimate details regarding their sex life, and something about a beach trip, but my head was too consumed with itself to pay attention.
Back in my dorm room, I stood in front of the bathroom mirror. I poked at the dime sized bruise directly above my collarbone. It wasn’t big but it was dark purple. A teeshirt would nearly conceal it, but not if I moved at all. Foundation wasn’t going to cover it much, either. I sighed. It was two days ago but still looked like it was from the night before. I reached into the striped zipper pouch that held what little makeup I owned.
*I can at least make it a little less noticeable,* I told myself as I pulled out the small bottle of foundation.
Rory’s voice came, muffled, through the door, “Oh hey! Carol, right?”
*Fuck*. I dropped the bottle back into the bag.
“Yeah, come in! Oh, she’s just in the bathroom. Bethany, your sister’s here!”
*Thanks Rory*. I dug my fingers into my temples and closed my eyes. *Not right now. Not today.* I hadn’t seen Carolyn since that night, nor had I really spent much time with her and other people since we started sleeping together. I could just imagine the complete lack of control my sister showed making a mess of things, but I knew I was completely trapped in the bathroom and decided I might as well get on with it. *Maybe this’ll be quick.*
Carolyn was wearing a black cropped blouse with poofy sleeves and a matching black pleated skirt that rested just above the white socks that came up to her knees. Her hair was pulled back into matching tails, one blue and the other green. She knew how I felt about pigtails. She knew how I felt about that look in general. She was trying to tempt me. I took a guess at what she had on under that skirt.
“Hi!” Carolyn chimed and wrapped her arms around me.
“Hey.” I said, coolly, as she practically danced. The hug was lasting a long time and I could feel anxiety spinning webs in my chest. I looked to Rory to see if they were staring. No, wearing a dark red bikini top and a pair of black boardshorts, they were focused on the phone in their hands. I allowed myself a smile and stole the chance to give my little sister a squeeze in return.
“In the area again?” I asked, prying her off my body.
“Actually, I thought we might get lunch?” Carolyn offered, “I’ve got neeeews.”
“I—“
“Hey yeah,” Rory said. “You guys should come to the beach with us!”
“But—“
“Please!” Carolyn clasped her hands together and gave her best pout. Looking the way she did, I was tempted to give in.
“I’ve got lunch plans.” I said. “I haven’t seen Olivia in weeks. Sorry.”
“Aw.” Rory frowned. “Next time then. Speaking of, I’m out.” They grabbed a small duffle bag from their bed and slung it over their shoulder. “Nice seeing you again!” Rory closed the door on their way out.
Carolyn wasted no time, throwing herself at me before the door latch clicked.
“Wait!” I cried, but she didn’t heed my plea. Like she was made of liquid, her body surrounded me. Her arms slid around my waist, pulling me into her, and up to hold the back of my head, her leg lifted and locked her knee behind my hip, and her tongue made contact with my neck. “Wait, no! No no no wait!”
“I’ve been waiting.” She panted in my ear. “I’m tired of waiting.”
“Carol! Stop…” I involuntarily whimpered when she bit my shoulder. I then realized that my hands were on her hips, not pushing her back but pulling her into me as she pulled me into her. Her tongue ran up to my ear and a moan escaped my throat.
“Lock the door.” Carolyn said, planting heavy wet kisses across my skin.
“It doesn’t.”
She paused long enough to look around the dorm. Smiling wickedly, she snatched the chair from my desk and wedged it under the doorknob. “Now you’re all mine.” Her eyes were already fucking me.
“B-but.. lunch…”
“I think you better cancel.” Carolyn was slowly stepping toward me. Stalking me like a lioness looking to feed.
My face was on fire. All reason to resist had been burned away by my sister’s lust. I scooped my phone off the small dresser beside me. *Sorry Liv.*
Carolyn was starting to circle me, her eyes like molten steel. When she finally lunged it sent me flailing backward onto my bed and my head hit the wall with a solid thud.
“Ow..” I started to complain, but she was immediately on me, climbing onto my lap and straddling my thighs. Wearing only shorts, I could feel her heat on my legs. I slid my hands up her sides and under the edge of her blouse and smoothly pulled it over her head. No bra underneath, as was her preference and always had been, left me with her perky handful-sized tits in my face. I pulled her to me and wrapped my lips around a hard little nipple. She gasped and ran her hands up my shoulders to the back of my head. I flicked the sensitive nub with my tongue and sucked hard. Her body trembled.
“Fuck.” Carolyn moaned. Her hips began to move, desperately trying to rub her clit against anything she could.
Doing the big sisterly thing, I reached under her skirt to offer some relief. As expected she had forgone underwear again. “Slut,” I growled from between her breasts then sunk a pair of fingers into her. She cried out wordlessly and immediately clamped down on the invading digits. I bit her just next to a nipple and started to fuck her slowly. Her hips still gyrated on my lap as small whimpers and moans leaked from her half-open mouth.
I adjusted from pumping her pussy to circling her clit and she stopped moving completely, her fingers tightening in my hair. I switched to the opposite nipple and bit down. She cried out and began to lightly tremble.
“Don’t stop.” She begged, squishing my face against her body. “God, don’t stop.” Her hips were jerking, but I kept my hand glued to her sex. I started to whip my tongue across the nipple between my teeth. She let out a long, low moan. My sister began to shake in my arms as the orgasm tore through her. I felt a hot wetness trickle down my thighs and she collapsed onto me.
I cradled her gently as she caught her breath. I felt the words bubbling up and this time I didn’t try to fight them. “I love you, Carol.”
Carolyn sighed and lifted her head to meet my eyes, “I love you, too.” She pressed our mouths together and I felt her tongue play at my lips. I opened to invite her in and a duel began, quickly building in intensity. Her hands snaked under my teeshirt and each claimed a breast, squeezing firmly.
I sighed happily into her mouth and sucked on her tongue. My hands squeezed her thighs and I was, once again, able to solely focus on the beautiful woman before me.
Carolyn grabbed the bottom of my shirt and pulled the garment over my head, throwing to the floor. I laughed and wrestled her down onto the mattress, pinning her arms to her sides and licking her cheek. She smiled up and me and bit her lip.
“I’m gonna ride your face.” I cooed. She nodded fervently and I kissed her again. Then I stood and dropped my watermelon styled shorts down to my ankles.
I heard the doorknob twist and I froze. Only in this instant did it occur to me how it would look to have locked myself into the dorm with my sister. In slow motion, I watched it open. *Open?!* The door opened outward, into the hall. The chair dropped uselessly to the floor.
“The hell?” Rory bent down and stood the chair back up. Then they pushed it aside, stepped into the bathroom, emerged with a towel under arm and reached the door again before they stopped dead. Their head slowly turned until they had an eyeful of my sister and I. “Uhhh…”
