A prequel continued: My hot alt girl friend, Julia, didn't want to just hook up with me. Part 18. Sam is her dirty little secret.[M21/F28][fucking][sneaky sex][age gap][oral]
Killian and I gave each other lots of flirty looks, when I would come work in the lab, that week following the first time we fucked. She'd told me we needed to be discrete about our hooking up, and so I tried to act like I did before we hooked up. There was one day, we were working in the lab, and there were other people in the lab. We kept giving each other flirty smiles, when no one was looking. She groped my ass, as she walked past me at one point, then looked back at me, giggling.
There was a small lab, off the main lab, that had no window on the door, because it was sometimes used as a dark room. I was in there doing some things for Killian, when she came in to see how I was doing. She moved up next to me, as I stood at the bench top, "How's it going, Sam?"
"It's going pretty well. I should finish this up in the next 15 mins or so."
"You're doing a good job, Sam," as she was inspecting my work. She smiled at me, and leaned in to kiss me. I turned, so we could kiss, but I was wearing latex gloves and could not touch her. So, we stood apart, kissing for a minute. It was like that for the rest of the week. We found private spots to hug and kiss each other. I was dying for more. That Friday, I happened to be walking through the parking lot to get back to my apartment, when Killian drove up next to me with her window down. She whistled at me, and I turned to see it was her.
I walked up to her car, "Hey Killian." I looked around to see no one seemed to around.
Killian was smiling up at me. She looked around nervously, then beckoned me to lean down, so we could kiss. She broke that off quickly. "Come in on Sunday, Sam?"
"Absolutely."
She giggled at my eager response.
"What about now? Take me home with you?"
Killian said, "That is sooo tempting Sam, but I have a thing tonight."
I eyed her suspiciously, "A thing with a guy? Like a date?"
"It's cute that you are jealous, but no, not a guy." She nervously hesitated, "You're the only guy, okay, Sam? I'd better be the only girl." She was looking at me with raised eyebrows.
"You're the only girl."
"I have this lecture I have to attend and sort of work at it. A PhD is a lot of work, Sam. And, I don't have a ton of time for dating."
"yeah, I get that. I have band practice all day on Saturdays."
"That's okay, I have a lot of writing to do. Just come in Sunday," and she winked at me, before driving off.
I eagerly awaited going in on Sunday. Luckily, my Saturdays were always busy with band practice, so that helped me impatiently bide my time. When I went into the lab on Sunday, I heard Killian giggling. I was stunned looking at her, because she was just wearing some boots, a sexy black thong and a little top, that ended above her belly button. She was bright red, standing there. I moved towards her, and she giggled and ran away. I was chasing her through a couple of labs that were interconnected, before she stopped and turned to face me.
We grabbed each other and kissed, my hands wandering over her exposed ass cheeks. She pulled away, "We have work to do."
I gave her a pleading look.
"No, only if you do a good job."
Killian told me what to do that day, then said, "I will be at my desk analyzing some data, if you have any questions. Bring me your lab notebook, when you are done." I stared at her exposed ass, as she walked away.
She had a small cubicle in one of the big lab rooms, and she went there to do some work, sitting on her chair in her underwear. I started incubating something and set a timer, then wandered over to her desk, just staring at her, with a grin on my face. I could see one of her long legs from the side, as she sat in her chair, her leg exposed all the way up to her hip, with just that waist of the thong interrupting my view of her bare skin.
"Do you need something, Sam?", she turned to look at me, forcing herself to keep a serious expression.
"You look hot in your glasses." She only sometimes wore glasses, but she had that hot nerd look about her, when she wore them.
"Thank you, but did you have a question? I believe you have plenty of work to do." She was still forcing herself not to smile.
I had to think of a question, as an excuse for being there, so I made something up, "I'm supposed to pellet this in the centrifuge at 3000 rpms right?"
She gave me a little smile, knowing my ruse, "Yes, but you knew that. You've done it a bunch of times, and I know you're smart. It's also in the protocol I gave you and I know you can read..."
I was just grinning and looking up and down her body, but then my timer went off, "I just wanted to be very sure." I turned to leave her.
She walked through the lab a couple of times, definitely for the purpose of letting me see her ass in that thong. I was not discrete in my ogling and did not try to hide my muttering of, "Fuck me...so hot..." She would giggle and go back to her desk.
When I was done a couple of hours later, I walked back to her desk with my lab notebook. She stood, and said, "Sit down..." gesturing at her desk chair. I sat down in the swivel chair, and she stood in front of me, leaning on her desk and looking at my lab notes. I was staring at her crotch. I ran a hand up her inner thigh, then she pushed it away, and gave me a fake stern look, "Not yet, Sam." She continued reading my lab notebook, while I looked up and down her legs and crotch, up to her beautiful face. My dick swelled in my pants.
She finally closed my lab notebook and set it down on her desk, then said, "It looks like you did a good job today." I rolled the swivel chair closer and ran my hand up her inner thigh again, only this time she did not stop me, and I rubbed her pussy some through her underwear. I moved in even closer, so I could kiss her milky white thighs a bit, while touching her pussy. I heard her breathe in deeply, and I looked up at her smiling face. I kissed her crotch on the outside of her panties, my lips feeling her puffy labia through her underwear.
I slid the crotch out of the way, getting my first good look at her pussy, then moved to give it a little lick, tasting for the first time. She made a happy little cooing noise, encouraging me to continue. Her underwear was kind of in the way, so I started pulling it down and she was bright red, as she helped me get them off, over top of her boots. She was standing at her desk, naked from the waist down, and she was clearly nervous. We would hear someone coming in time. The only entrance was in the other room, and this lab had an ante chamber for positive air pressure. We would hear a door and then there was another door. She had a long lab coat she could throw on, hanging right there. Still, the risk was fun.
She had really dark bush that I liked. I liked how it looked against her pale skin. Just a neatly manicured bit of very dark bush between her legs. I kissed up near her prominent pelvic bones, then kissed right on her mons and in her bush. I moved lower to lick her clit a little and she whimpered. I encouraged her to slide up onto her desk, so I could have better access to her pussy. She put her feet up on the armrests of the swivel chair I was sitting in and spread her legs for me, with her bare butt on her desk. I'd wanted to do this to her for a long time, and I took my time, savoring her taste, enjoying getting her off, doing a good job.
I slid a finger inside her, while licking around her clit. I looked up at her and saw her biting her lip, then she threw back her head a bit in pleasure, before I looked back down, focusing on my work. Her legs bucked and she almost rolled me away, while I sucked on her clit. I could hear her breathing get more strained, and then she started panting a bit, as I continued licking her, lapping up her wet pussy. She made some high pitched whimpers and squeezed my face between her legs some, but I kept going. My cheeks were wet with her secretions, and I was making horny noises, while loving eating her out. I got her off repeatedly, then could not take it anymore.
I abruptly stood up, unzipping my jeans and shoving down my pants and underwear, my hard cock springing out. She panted out, "Yeah...", her brow furrowed a bit, while she stared down at my dick. I moved forward, sliding it into her easily, she was so wet. I had those long legs wrapped around me. I was holding them up a bit, by grabbing her thighs. We kissed each other aggressively while I fucked her on her desk. We were both making horny moans into each other's mouths, while kissing and fucking. As I got closer, I whispered in her ear, "Where should I cum?"
She whimpered a couple of times, and responded, "Cum inside in me..." My dick started twitching inside her and I shot cum deep inside her. Her legs squeezed me tighter and I felt her vagina grip my hard dick, while she whimpered out, "oh my god, Sam...fuck me..." I kept thrusting with her pussy extra slick with my cum. She started gently pushing me out of her, giggling a bit, as we both looked down to see my cum leaking out of her onto her desk. She hopped up and grabbed some tissues from a box on her desk, wiping between her legs and on her desk.
We stood kissing for a minute, my hands all over her bare ass, then stopped and got dressed again. She put a skirt on over top of her underwear now. We shut down the lab, and started walking out of the building, and I said, "What are you doing the rest of the day? Tonight?" It was still early afternoon.
Killian turned and smiled at me, "I have a lot of work to do. Just going to hole up in my apartment and write."
"I have a bunch of homework too." I was giving her a hopeful look, wanting an invite to stay over at her place.
Killian knew what I was hoping for and gave me a little grin, "Sam, I feel like you would be very distracting for me."
"You have to take some breaks while you are working...keeps the creative juices flowing."
She burst out giggling, "Sam, fine. Do you have your homework with you?"
"No, we could swing by my place?"
"Sam, I told you that we have to be discrete."
"You could just wait out in your car, and then I'll get my stuff?"
"Okay."
She looked nervous, parked outside my apartment building. I kissed her and said, "I'll be right back." I ran inside and grabbed some books, some clothes, and my toothbrush, then ran back to her car. "None of my housemates were home."
"Good." She kissed me on the lips, and then we started driving to her place. We got to her apartment building, which was an old brick building of garden style apartments. I was kind of nervously excited to be going into this grown woman's apartment.
She walked off towards her bedroom, "I'm going to go get changed." I wandered around her tiny apartment, looking at stuff. She came back out of her room, dressed in sweat pants and a baggy t-shirt. She looked kind of embarrassed, because maybe I was staring at her, "I told you that I need to write, so I am wearing comfortable clothes."
I walked up to her to hug and kiss her, "This outfit is hot."
She busted out laughing and gently pushed me away, "God you're horny." Then she wandered over to a table covered in journal articles, notebooks, books, etc, and sat down. I stood there looking at her. She gestured for me to go away, "I told you I have work to do."
"Fine." I grabbed my backpack, and pulled out some clothes to change into, because I didn't feel like wearing jeans around her apartment. I went into her bathroom, and changed into some sweatpants that I brought. I saw her look up at me with a grin, as I came back into the living room/dining room/kitchen area of her apartment. "Get back to work, Killian," and I grinned at her.
She just shook her head and buried her face in her work again. I sat on her couch and started doing my homework. I was mostly good, just working in silence, but occasionally she busted me looking at her.
Killian looked over at me from her table, "Why are you staring at me?"
"I'm just working, and I was staring off into space."
She gave me a little grin knowing that I was not staring off into space. I got back to work, and eventually, she got up to get some water from her kitchen. She stood in front of me, drinking her water, looking down at me. I pretended to ignore her, just looking at my text book.
She said, "Biochem?"
"Yep."
"I love biochem."
I laughed, "Me too. It's just like fun little math problems."
Killian set her water down on a side table, then grabbed my book away, setting on the couch next to me, so that she could straddle me, sitting in my lap. She kissed me, "So, you're a nerd, too?"
"Well, maybe not as big of a nerd as you..."
She made an exaggerated angry face and tickled me aggressively. She stopped and kissed me some more. I moved my hands up to feel her nice tits on the outside of the baggy shirt she was wearing, then moved down to her hips and finally put my hands in the back of her sweat pants. I could feel that she was wearing different underwear, "Hmmm...you're not wearing that thong anymore."
She stopped kissing me and laughed, "Yes, I changed."
I pulled on the front of her sweatpants to take a look at them. They were ordinary, grey, bikini cut panties. "These are hot."
Killian laughed, "These are like the most ordinary underwear ever."
"Take off your sweatpants. I want to see them."
Killian shook her head, laughing a little, as she stood up and then slid down her sweatpants, kicking them off. She turned around 360 degrees, and said, "See, just ordinary underwear."
I pushed down my sweatpants and underwear enough to show her my hard dick, "I like it."
She burst out laughing at my exposed erection. "You are so horny."
I twitched my dick around in response. Killian had a bemused look on her face, as she sank to her knees in front of me. I was breathing more rapidly just from the excitement that she was about to suck my dick, before she even put in her mouth. She pulled down on my sweatpants and underwear more, until she pulled them all the way off. Then she leaned in and grabbed my hard cock, giving it a couple of kisses, and then licking it. It went into her warm wet mouth and I moaned, "oh my god, Killian..." She giggled a little with it in her mouth, then pulled her mouth off, looking up at me and stroking it.
"I knew you would be a distraction," and then she put it back in her mouth. I gasped a bit at the pleasure she was giving me.
"Fuck that feels good." She was just bobbing her head up and down, taking in just a bit more than the tip on each downward movement.
Killian pulled her lips off with a slurping sound, then stood in front of me, taking off her panties. She climbed into my lap, straddling me, and then guiding my dick into her, slowing moving up and down on it, until she had the whole thing inside her wet pussy. She kissed me while riding it, then whispered in my ear, "You're a good distraction."
I moved my hands down to her bare ass cheeks, while she bounced on my hard dick. She sank all the way down and rocked her hips around with my dick all the way buried in her. She knew how to edge me and make it last. She was watching my face and my little whimpers, slowing and sometimes stopping her movements to stop me from cumming. She went back to bouncing on it in a regular rhythm and she was making some high pitched whimpers. "Fuck...Sam...oh my god..." She panted that out and I felt her pussy squeeze my dick. My dick twitched inside her, as I spurted cum. She leaned forward kissing me, and still slightly moving up and down on my dick, very slowly. I could feel the extra slippery feeling of my load inside her. She kept squeezing my softening dick with her pussy.
She gave me one more kiss, then slipped herself up off my cock. I made a disappointed groan, as my dick was out in the harsh cold world again, leaving her cozy warm pussy. She laughed at me, "I have to get back to work." I watched her bare ass, as she walked away to go use her bathroom. She put her clothes back on and I went to her bathroom to wash off my dick, then got dressed again.
We went back to working in silence and I saw that she had a really intense look on her face, as she read a journal article, then scribbled some notes. I could practically feel how smart she was just watching her work. I eventually finished most of my work, and went into her kitchen looking in her refrigerator.
I looked out over the counter into the living room/dining room area, "Soooo...I guess you just don't need to eat, Killian?"
She laughed, "There's food in there..."
"Oh yeah, so much food...there's let's see, some yogurt...a bottle of salad dressing...some expired milk..." She was red faced, embarrassed.
"I haven't had time to go shopping."
"I'm going to make you dinner."
"You can cook, Sam?"
"Oh yeah, I know how to make a few things. Give me your car keys and I'll go to the store."
She looked at me with raised eyebrows, as she handed me her car keys, "Be gentle with her. I can't afford to replace her."
"Of course."
"Oh, the only thing is that I don't have any money, Killian." I burst out giggling.
"Get my purse."
I handed her the purse, and she eyed me suspiciously, as she handed me her debit card, then told me her PIN. "Don't go crazy with that."
I bent down to kiss her, "I'm just going to get some stuff to make you dinner and some stuff for breakfast."
"Okay, thanks." She pulled me down for another kiss. "Get me some new milk, please? And some fruit."
I left her and went to the store, and bought stuff to make her a lasagna, so she would have some leftovers to eat too. When I got back to her apartment, I started to say, "I bought stuff to..."
She loudly shushed me, and waved her hand indicating I should go away. Killian was an intense girl and quite smart. When she focused on her work she did not like to be interrupted. It came off rude, but it did not really bother me. I just went into the kitchen and started working on dinner. Once, I had the lasagna in the oven, I was making a salad to go with it. Killian came into the kitchen, hugging me from behind, "I'm sorry for shushing you. I just was really forming an idea there." She kissed my cheek from behind.
"It's okay, I like seeing you work." I turned to kiss her some. She took a break for a bit, so we could eat dinner, then went back to work. She worked pretty late and I got tired. "Hey Killian, sorry to interrupt..."
"It's okay, what's up?"
"I'm getting kind of ready to go to bed."
"You can go get in my bed. I'm staying up working for a bit."
I came over to her to kiss her goodnight, then took a shower and got ready for bed. It felt kind of funny to go get in her bed, with her still out there working, but I fell asleep eventually.
I woke up in the morning, with her snuggled up to me and I had no idea when she came to bed. Her alarm went off soon after that, and after she turned it off, she smiled at me, and snuggled up to me more.
"When did you come to bed?" I was running my hand up and down her body, grabbing her ass.
"It was about 2am."
"Damn."
"I work really well late at night."
We kissed some and I put my hand up in her top to feel her bare tits. I started pulling up on the big t-shirt she wore to bed. "I've never seen your tits, but they seem like they'd be magnificent."
Killian laughed out loud and pulled off the shirt, exposing her beautiful bare breasts to me. Her natural tits were quite full, and really stood out on her thin frame.
I gently felt them, while looking at them, "I was right." I moved in to suck on one of her nipples. She giggled a little. She made some happy noises, as I slid my hand into the front of her underwear, touching her pussy some while sucking on her tit. I was sliding my fingers in out of her pussy, and I could feel her getting wetter. I kissed her neck some while fingering her, and then moving my slick fingers around her clit. One of her hands drifted down into my boxers, stroking my hard dick. She was kind of on her back, while I touched her, and she was having trouble keeping any kind of steady rhythm to stroking my dick.
I stopped touching her, and slipped off my boxers, throwing off the covers too. She lifted her hips to help me pull off her panties, as she laid on her back. She spread her legs for me to move into missionary, sliding my dick in her wet pussy. She wrapped her long thin legs around me and pulled me down to kiss, while I fucked her in missionary. We both made some little noises, as I slowly thrusted all the way in and out of her slick hole. We aggressively kissed each other, while I fucked her. I started fucking her faster and harder, no longer able to hold back and she whimpered out, "yeah, yeah, yeah..."
I groaned, "oh my god..." as I thrusted and shot cum inside her.
I felt her nails in my back a little, "oh fuck...Sam..." Her legs squeezed me tighter and her head rolled back a little. We kissed with my dick still in her, until she gently pushed me off. "I have to get ready to go into the lab."
"Yeah, I have a 9am class."
We took a shower together, and I stood behind her, feeling her nice soapy tits, while she washed her face and hair. My dick got hard again, from the nice feeling of her soapy ass in front of me. She turned around, rinsing her hair, and grinning down at my erection. She grabbed the soap, and soaped up my dick, then stroked it with her slippery fingers. She moved out of the way to rinse my hard dick in the shower, then she lowered herself to her knees in the shower.
She looked up at me and said, "I'm sorry for shushing you last night." Then she put it in her mouth. I just gasped, "Okay." She did not take her time. She was in a hurry. She gave me an aggressive blowjob, never taking her mouth off, and also using her hand at the same time. I kept moving up on my toes from the pleasure. She was in a hurry to get me off, so she could finish getting ready. She blew me so aggressively, I came pretty quickly even though we'd just fucked. She stood up with a grin, rinsed her mouth in the shower, then turned to hug and kiss me.
Killian stopped hugging me, then gently grabbed my semi hard dick, and wagged it, "Nice penis." Then she turned off the water and we both dried off.
We got dressed and then I made us some breakfast, while she did her hair and makeup. I packed her some lasagna for lunch too. I handed it to her, "So, you don't forget to eat lunch."
"Thanks."
She drove me the short drive to campus, "Which class do you have at 9?"
"Biochem."
It was in the same building as her lab. She laughed, "I'm really sorry, Sam, but I'm going to have to drop you off a few blocks away. It will be too obvious, if we pull into the Life Sciences building parking lot together."
She stopped the car, looked around nervously then kissed me. "Sorry, Sam."
"It's okay. I'm going to just think about that blowjob, while I'm walking." She lightly smacked my arm and giggled.
We actually arrived in the lobby about the same time, and pretended to greet each other, like we had not just spent the night together. We rode the elevator up together, giving each other some little glances, but trying not to be obvious since there were other people in there.
