Instant Chemistry [F19/M20s](First Time)(Vanilla)

Lily walked into the lab and unpacked her notebook and pencil. She went to put on her goggles when the teachers assistant leading today’s chemistry lab cleared his throat. Lily looked up, realizing that as the only other person in the room, he must be trying to get her attention. Tyler, the TA, couldn’t have been too much older than Lily herself. He looked mid 20s at the oldest to Lily’s 19. He led the chemistry discussion group Lily was assigned to as well, and he had always seemed very kind, if a bit of a nerd.

“Yes, sir? Did you need something?” Lily still wasn’t sure what to call all of the different teachers at the university yet. Some were professor, some doctor, some just wanted to be called by their first names. Lily stayed on the safe side and addressed most by ma’am or sir.
Tyler seemed to blush a bit as Lily waited for him to answer her. She knew that her direct stare was sometimes a lot for people, but she had been taught that it was a sign of respect to maintain eye contact. Tyler seemed to think though that this was a staring contest. “Sir? You wanted me?”

“Um, Lily, right? Yes, of course, I know you’re Lily. Ha ha…Um. Anyway. So, I need a bicycle drawn on the board to explain a concept today. I know that you’re an artist, and I’m terrible at drawing, so would you mind drawing one for me?”
Lily arched her black eyebrow quizzically at Tyler.
“How do you know I’m an “artist”? I mean, I do take design classes, but…” Lily trailed off as she realized how accusatory she was sounding. And it seemed to make Tyler a bit nervous. This made Lily even more confused as she was often described to be as intimidating as a sugar cookie.

“Oh, um, well, I just meant that you’re artistic. Your notebook has drawings, very good drawings, all over it. And you always have different flowers drawn on your hands and arms. I’ve seen you doing them, so I know it isn’t your boyfriend who’s drawing them.”
“Oh! Boyfriend? Hahahahaha, what? I don’t have a boyfriend! Weird. Yeah, I can try to draw a bike. I’m more used to organic more than mechanic, but I’ll try my best.”
“Oh, Lily, thank you. I’m sure whatever you come up with will be just wonderful!”

Lily decided that Tyler was weird, but still nice.
She got to work drawing the bike, trying really hard to remember what the hell a bike looked like despite seeing them ridden through the quad constantly. She drew, erased, drew again when she remembered there were chains here and gears there. Eventually, she clapped her hands to remove some chalk dust, set her hands on her hips, and stood back to admire her work.
But as she took a step back, she met resistance. Warm, hard resistance.

“Oof!” Said Tyler from directly behind her.
Before she could step away, Tyler put his hands on Lily’s shoulders to keep her in place.
She felt his warm breath ruffle the curls on the back of her neck that had escaped her ponytail.
Tyler’s lips were suddenly at Lily’s ear, whispering, “Oh, beautiful Lily. I want you. Do you feel how hard you make me?”

And Lily realized that she could feel his hardness as he rubbed against her lower back.
Tyler stilled and dropped his hands as they both heard voices and footsteps in the hallway. The other students were coming to the lab since it was almost time to start. Tyler and Lily jumped apart right before people started coming in the door.

The lab went about as expected. A bunch of teenagers playing with fire and chemicals to make the flames burn in lots of different colors. While usually completely enthralled by the experiments done in lab, Lily found it very difficult to focus on the flames on the table. She was however very focused on the scorching glances she kept catching from Tyler, and the burning desire between her own legs.

After the lab was done and the other students cleared out, Lily took her time repacking her supplies. She promised her lab group that she would take the supplies back to the closet so they could go to their next class. She was reaching up to put one of the powders back on the shelf when she heard the door close and the lock snikt into place.

“You don’t have anywhere to be anytime soon, do you, Lily?” Lily felt strong arms come around to embrace her from behind before the palms of Tyler’s hands were suddenly on her full breasts. Lily’s breath hitched at the same time that Tyler let out a tiny moan. “Oh, Jesus, they’re even bigger than I realized! Lily…”
Tyler kneaded and massaged Lily’s breasts through her sweater. Lily felt her nipples harden against the sheer fabric of her favorite lace bra. One of Tyler’s hands slowly found its way to her hip, then up underneath her sweater. Lily pushed her ass out against Tyler searching for his erection as she leaned further into the shelves in front of her.

Both of Tyler’s hands were under her sweater now, and his breathing was growing heavier as Lily ground her ass against his pelvis. Lily’s sweater was suddenly shucked off and tossed to the side. She turned to face Tyler. “Tyler, I don’t know what you expect from any of this. I don’t want to think about anything more right now than you being inside of me as soon as possible.” Tyler looked momentarily shocked that sweet, quiet Lily was saying something like that to him.

But he was so turned on that he suddenly became a man of action.

All of his days spent with his high school girlfriend patiently teaching him how to take off her bra came in handy. He unhooked the back, then slowly peeled the straps down Lily’s soft shoulders. The underwire seemed to cling until the last moment when Lily’s breasts suddenly dropped and jiggled in the most enticing way. Lily had been trying to figure out how to get Tyler out of his clothes too when she had to stop at the look of hunger on his face.

Lily had always wondered how it would feel to have a man lick her nipples. It always sounded nice, and it led to many nights where Lily would pinch and roll her own nipples between her fingers while laying in bed imagining the scenarios where this would finally happen. But this was more than she had expected. Tyler seemed to be devouring, no, worshiping Lily’s breasts. He licked, nibbled, used his lips to capture and pluck Lily’s sensitive tan nipples. She could feel a zing shoot from her nipples straight to her pussy. Lily grew wet and felt her first orgasm start to build.

Tyler held her by her shoulders as he continued to feast on her breasts, working a little bit harder as he felt the little shivers he caused in Lily. He stopped for just a moment to take his own shirt off, correctly interpreting the meaning of Lily’s grasping hands. They both wanted bare flesh against bare flesh. Lily’s hands were in Tyler’s hair, grabbing and pulling him closer to her breasts. Then on his shoulders. Then he chuckled with his mouth still around her nipple as he felt her push him gently downward.

So he obliged Lily and sank to his knees in front of her. He had long admired her chubby thighs in the blue jeans she often wore. So he took this opportunity to run his hands up and down her hips and thighs, over and over, appreciating how she stretched the material. Her hands still on Tyler’s shoulders, Lily did a little shimmy of anticipation as Tyler unbuttoned and unzipped her jeans. He slid her jeans down her legs, stopping to slip off her shoes before helping her to step out of the jeans.

Then he looked up at her pretty little underwear. He had never seen such delicious-looking underwear in real life before. His Lily, object of so many nighttime fantasies, was standing before him in only her rainbow striped knee socks (because of course she was wearing rainbow striped kneesocks) and a skimpy scrap purple lace. A scrap of lace that was noticeably damp.
Lily shook as Tyler pressed his nose to the fabric covering her clit and breathed her in deeply. “Mmmm, Lily…you smell like sex and strawberries…”

Lily couldn’t help the giggle that escaped her lips. She was so turned on, but it just struck her as funny to be sniffed. And it tickled a bit. She had a brief moment of terror worrying that Tyler would be turned off by the errant giggle. But he looked up at her with such a big smile on his face that she needn’t have worried at all. “Lily, I just love your giggle. Are you ticklish? How about here?”

Tyler moved her panties to the side to tickle her clit with the tip of one finger. Lily nearly collapsed with the desire it sent to her core. The wicked gleam in Tyler’s eyes confirmed that he was teasing her, and that he loved her reaction. “Ok, Lily. Turn around and brace your hands on the shelf. Good girl. Now, bend a bit and spread your legs. Now make sure you hold on tight so I can take my fill of your luscious pussy.”

Tyler’s sudden dominance struck a chord deep within Lily that she didn’t know she had. So she was more than happy to obey his commands.

Tyler flattened his tongue and licked Lily through her juicy folds from her clit down to her vagina. He repeated this several times, relishing the quaking of Lily’s thighs each time he made the circuit. Then he added his fingers, tweaking her clit as he lapped at her vagina, collecting as much sweet nectar as she could give him. Which seemed to be quite a lot. Our Lily was a very wet girl!

As he rubbed circles around Lily’s clit, Tyler speared his tongue into Lily, pressing towards her front where he hoped he’d find her g-spot. And based on the flood of liquid into his mouth, he definitely had. The accompanying moan helped him verify his findings as he flicked his tongue again and again. Lily couldn’t stand any longer, and she couldn’t hold onto the shelf since her arms seemed to turn into noodles. So she collapsed slowly down into Tyler’s waiting embrace, panting heavily as her body sang with aftershocks of her strongest orgasm to date.

Tyler arranged himself as he waited for her to come back to him. Lily came back to awareness on Tyler’s now naked lap, facing him and kneeling with her legs on either side of his. He placed her hands back on his shoulders and asked, “Lily? May I fuck you now?” He extracted a little square foil packet from his discarded pants pocket with the question still written on his face.

“Oh god, yes!” Lily replied a little more enthusiastically and loudly than she’d meant to, so she threw a hand over her own mouth in embarrassment. Tyler chuckled and reassured her that the lab wasn’t scheduled for any other classes for today. So she could be as loud as she wanted as long as she didn’t scream “fire”.

Tyler rolled on the condom as Lily stared wide eyed at his massive cock, wondering just how that was supposed to fit inside of her. She wasn’t petite by any means, but she was still a virgin. Not counting toys, of course.

Tyler held his erect cock and directed Lily to position herself above him as he placed the head of his cock at her entrance. Ever eager despite the concern size, Lily eased down onto Tyler. Being in charge of the delicious invasion, Lily was able to stop and adjust to the feeling of stretching and fullness she was experiencing. The strained look on Tyler’s face was softened by the encouraging words he gave her. “Ok, baby. Take your time. This isn’t a race. Oh god, you’re exquisite. Fuck, you’re so soft. And hot. And wet.”

Once Lily was fully seated, she took a moment to enjoy the feeling of finally having a real, throbbing cock inside her hungry pussy. But once the moment had passed, Lily felt the overwhelming need to move. With her hands on Tyler’s shoulders, she started with a bit of rocking, grinding her clit on the base of Tyler’s hard cock. Tyler seemed to like that a lot, so Lily got confident and tried something more. She did a slow little hula hip shake, and based on his moans, Tyler liked that as much as Lily did!

She eased up on her knees then, and slowly sank back down. She tried that a few times, clenching her inner muscles as she rose and releasing them as she eased back down. That seemed to be when Tyler lost his last ounce of control.

Tyler took Lily in his arms, quickly laying her on their pile of clothes before starting to increase the pace she had set torturously slow. Faster and faster he pumped in and out of Lily until he could feel her clenching around him. She cried out, digging her nails into his back as she came all over his cock. He pumped erratically a few more times before emptying into Lily, a bit sad that there was a condom between them.

Tyler pulled Lily with him to lay on their sides, still sheathed within her. As they both panted and tried to blink the stars from their eyes, he kissed everywhere he could reach. Her nose, her cheeks, her shoulder.
He slowly withdrew from her, tying off the condom and tossing it into the wastebasket near the sink. Tyler cuddled Lily close into his arms and smoothed the hair stuck to her forehead.

“Lily? Would you like to go on a date, maybe?” The dominant streak didn’t mean he had bottomless confidence, after all. And Lily giggled before agreeing to dinner that night.
