Fordham High School had an Advanced Robotics class with four whip-smart students. But the program was in jeopardy due to their teacher, Mr. Harris taking paternity leave. In his three-month absence no other teacher had stepped forward to supervise the students. Left to their own devices they departed from their normal projects to begin a sexier experiment that would have never been approved if they had been properly supervised.

At Ken and Jaden’s suggestion, they started researching ways to insert remote controlled warmers in undergarments to help outdoor workers in cold climates. Discussions amongst the two of them and their classmates Amber and Amy evolved after they discovered how to get pea sized nodules inserted in tightie-whities. The boys had to add another cotton layer to them but realized they were onto something. They informed the girls that they should test the theory by outfitting the girl’s panties and bras with the pods encased inside the cups and at the groin.

The girls were sceptical and saw this as a ploy for the boys to get them to divulge their bra sizes. Ken convinced the girls to sacrifice one bra and pantie each ‘for the team’. After the first attempt of wearing them outside at the girls’ soccer practice in November, Amy and Amber said it had worked at keeping them warmer.  

Then the boys went to work devising a way to make the nodules pulsate up to twice their size to about dime sized. In addition to that they were able to adjust the speed of the pods’ pulse rate remotely. They knew they were onto something but the girls refused to be guinea pigs as they knew what the randy boys were concocting.

“Ah, come on Amber! We went to a lot of trouble to get these panties and bras outfitted with ‘Warmers Version 2.0’. You don’t want your donated undies to go to waste, do ya? Be a good sport and wear them. Just for your next practice.”

“No way, Ken. It’s bad enough knowing you were running your hands inside the cups of my bra! And to what purpose? I know your game. You think that the pods will ah…’tickle’ me as well as keep me warm?”

Amber interjected, “Yeah, and I want my bra back. I bet you took them home and were fantasizing like all you nerdy guys do. Probably beating your meat inside of them. Ew! I say we scratch this project and go back to just the ‘Warmer Version 1.4’."

Ken, trying not be obvious about how he was leering at Amber’s ample 36C bosom (he had read the tag on her bra when he inserted the nodules) said, “Well, it’s not like I was running my hands inside your bra cups while you were wearing it. However, if you would consent for me to do that, I’d be…”

Amber interrupted, “No way, loser! Your little disgusting experiment or not, there’s no way you’re ever even getting to first base with me. This pulsating idea is idiotic and never going to work.”

Jaden says, “Okay. How about we bet. Ken and I watched these little pods grow and shrink in rhythm along with keeping their warmth properties. You gals wear this stuff and we’ll operate the remote sets from the grandstands. If it fails, we’ll…ah, help you prepare for your SATs.”

Amy frowned and said, “And what if you’re right? I guess you get to brag about how smart you are."

“Nah, nah…well, I guess we’d do that but you also have to…let us get to second base,” Ken giggled.

The girls conferred privately. “Okay, nerds. It’s a deal, sort of. But you are going to have to find another gal to wear these get-ups, okay? We’re sure you wouldn’t trust us to give you an honest report given what’s at stake. Go find one of those ‘whores in training’ in the junior class to be your test wearer.”

Amy continued, “Besides, unless you want to construct another bra, you better find a flat chested freshman to model for you. My bra won’t fit most seniors with my little 32a mosquito bites. We’ll have to use Amber’s.”

Jaden snapped his fingers. “How about your Chemistry teacher, Ms. Davis, Amy? You’re such a brown-noser maybe you could talk her into it! And she looks to be about Amber’s size ‘up top’.”

“Hmm, that might work. I’ll tell her it’s in the interest of science! And that it will help us win the Robotics competition. She always asks me about how we’re doing.”

The next day Amy and Jaden approach Ms. Davis after chem class. She was a second-year teacher, in her mid-20’s, average height and weight, with middle cut strawberry blonde hair with an infectious enthusiasm for her subject.

“I’d love to help you! I know that your Robotics teacher is out. I don’t know how smart I am about that robotics stuff so I don’t know how much of a help I could be…”

“OH, we want you to help us by being a subject of a new experiment. See, we’re developing a platform that will make people sustain colder temperatures in the workplace. It…ah…supplements their clothing. We would like you to take a few minutes to model them.”

“Sure, why not? Is your next after school Robotics session today? I’ve got some time after school.”

“Yeah…meet us in Room 310. See you after school, Ms. Davis.”

As the school day ended Ms. Davis got a text from Mr. Harris. “Amy texted me just now and said you were going to help them out with their experiment, Colleen. Thanks. These four kids work very hard. They have a way of thinking outside the box. I tend to give them a lot of leeway because last year their project was something I didn’t think would work but it won Fordham High the Regional Robotics Gold Medal! So, whatever their ideas are for this year, hear them out. Let me know how it goes.”

Jaden and Amy ‘high fived’ as they walked away.

Ms. Davis showed up in room 310 after school. The four students were there to greet her.

“So, where’s this clothing you want me to wear?”

The kids all stared at the work table where they had laid out Amber’s light pink bra and panties. They averted their eyes from the teacher sheepishly.

“Wait…what?”

Ken piped up, “Yeah, what we developed only works on undergarments. For this to be effective, it has to be close to the skin. That makes sense doesn’t it, Ms. Davis?”

“Just go to the john and …change into these and put your dress back on. You said you wanted to help, right?” Amy interjected.

“Hmm, I don’t know if I signed up for this, but okay. I’ll be right back. So, the ‘warmers’ are embedded in the cotton?”

“Yeah!,” all four of the students chimed.

“You kids better not be punking me. If you were other students I’d be out of here and reporting you to the office. But since it’s my two best chemistry students, I guess I can trust you. And I don’t know your friends here but if they are like you, they should be okay. I’ll be right back.”

Upon her return she was frowning disapprovingly as the four of them were smiling nervously as she smoothed out her dress, aware that the boys were probably mentally looking through her above the knee length dress, envisioning the bra and panties she had on underneath.

Jaden spoke up, “You like to sit on your desk when you teach so just do that on the work table here, okay?”

Ms. Davis complied and crossed her legs and self-consciously pulled her hem down as far as she could.

“Okay, Ken. You have the remote for the ‘warmer’. Let’s see if this works.”

Colleen thought she saw Amy wink at him when she said this.

Almost immediately she felt a wave of heat on her groin.

“Do you feel anything yet?”

“Yes, ah…this isn’t going to get too hot is it?”

“No, no…just enough to make you comfortable if you were outside. I only have the dial up to ‘three’.”

“Um, I’m not feeling it everywhere, just…it’s very localized. Shouldn’t I feel it over the whole surface?”

She started to squirm a little uncomfortably as she began to blush.

The kids gathered around closer and she felt their eyes on her lap.

Ken tripped the new pulsation toggle om the remote and Ms. Davis’ eyes widened as she sucked in a breath.

“Tell us what you are experiencing,” Jaden said as studiously as he could while stifling a giggle.

The pea sized nodules had been embedded in the panty up and down the cotton reinforced panty liner in two parallel rows a half inch apart with a strip of them across the top in an inverted ‘U’ pattern which was meant to surround the wearer’s pussy. The boys had guessed how far apart they should make the rows but without any practical experience with a woman’s genitalia, they looked at a lot of porn as ‘research’ for the best way to get the experimental pods inside the lips of a vagina but outside the labia. The bra was easier; just a circle at the tip of each cup.

This was why Amber and Amy refused to wear them once they saw them. They were aware of what the boys were trying to do. But they had admitted earlier that, if it worked, it would be fun to see what Ms. Davis’ reaction would be. They were a little nervous that she might get them suspended but Amy knew that she was teacher’s pet so she didn’t sweat it too much.

As Colleen started to squirm a little on the table, she began to nervously kick her feet up and down (the student’s wondered if it was nerves or something else). She closed her eyes and sighed deeply. Jaden winked at Amber, stifling a giggle.

“I…I think you have it turned up too high. I’m getting sweaty down there. And something’s moving. Is that supposed to happen?”

Jaden got bolder and decided to see if he could take it to the next level. He was aware that his erection was probably evident.

“Well, prop yourself up a little with your hands and we’ll …ah…arrange your dress so it doesn’t get wet… from your sweat, that is.”

The other three stared at him with their mouths open.

Amy piped up, “Yeah, we don’t want to ruin it or anything. It’s very pretty. You always dress so nice.”

They were all amazed when Ms. Davis did as instructed. With her palms on the table she locked her elbows and without uncrossing her legs her torso rose above the table a few inches.

Amber and Jaden quickly hiked up her skirt to her waist and she lowered herself back down, her pantie visible with a distinct wet spot between her closed legs. Their teacher blushed a little and tried to tug down her dress so that the kids couldn’t see her panties.

“Yeah, thanks. Actually, this needs to be dry cleaned. And…isn’t the bra supposed to warm up? I’m not feeling anything up there.” Her voice and cadence seemed almost trace like as she gulped a short breath.

Amber said, “Oh yeah, it’s my bra and maybe it’s a little too big for you. Maybe if we held it closer to you…?”

She pushed her hand onto her teacher’s left boob over her dress so that the bra pushed back onto her chest in order to make contact.

Smiling, she looked at Jaden. “Can you get the other side?”

Ms. Davis hung her head down as if falling asleep. “That’s not neces…Ah, yes…I feel it now, a little.”

Amy saw that Colleen was enjoying what was happening and said, “I’ll be right back.” She grabbed the other set of bra and panties from her backpack that the boys had made for her and ran toward the bathroom down the hall. When she came back, she had apparently put the bra and panties on under her soccer uniform top and shorts,. “Ken, do you have the other remote control for the set you made for my undies?”

“Sure thing, Amy. Got it right here. Have a seat next to Ms. Davis. We’ll see how it works for you.”

Meanwhile Jaden and Amber were pushing on the front of their teacher’s chest and doing a little bit of discreet squeezing as well. Amber noticed the tents forming in the front of both of the boy’s pants.

Even through Colleen’s dress, Jaden could tell that the nodules were expanding and contracting around where her nipples were. Ms. Davis’ breathing picked up and she emitted a quiet moan. Sitting next to her, it was obvious that Amy’s panties and bra were doing the same to her as she spread her legs wide and stared at Ken before saying,

“Wow. Maybe we could patent this.”

Ken positioned himself so that he could see between her legs. He saw the pods pulsating in and out surrounding her pussy even through her shorts. He was amazed that Amy let him get such a good look.

Jaden, ever the bold one, reached behind his teacher and unzipped her zipper from her neck down to below her waist. Amber silently shook her head no but it seemed a mild protest since he noticed that she just squeezed Ms. Davis’ boob a little harder.

As Colleen bit her lip she said, “OH, Jaden dear, don’t do that.”

“But Ms. D, we wouldn’t see anything more than we would see if you were at the pool in a two-piece swim suit, right?”

Ms. Davis turned that over in her mind and shook her head in the affirmative. She smiled at the swim suit reference as she recalled walking the beach in Punta Cana in her skimpy bikini. A middle-aged man at the outdoor café actually stood up and applauded as she strolled by. From the looks of the front of his microscopic Speedo she could tell he liked what he saw. The memory increased the sexual excitement she was feeling.

 “Well, this dress does wrinkle easily so maybe getting it off would be wise.”

With that Amber and Jaden lifted her dress up over her head. Deep cleavage was visible inside the loose cups of Amber’s bra.

Amy looked to her right and saw what was going on. “Yeah, it is getting warm in here.” She grabbed the hem of her soccer jersey and pulled it off. With both Ms. Davis and Amy in just their bras, the rhythm of the pea sized nodules at their nipples were visibly moving in and out.

Amber said, “Ms. Davis, my bra is just too big for you and we’re never going to get a good reading like this. Let me see if I can adjust the straps to make it tighter.”

She reached behind her teacher, pausing to see if there was going to be a protest. When there wasn’t any objection, she unhooked it and she and Jaden pulled it off her shoulders and down her arms slowly and off. Her rosy red nipples against very pert tits were exposed for all of them to admire. Colleen didn’t cover herself and smiled as she kept her eyes closed.

“Hurry up with that adjustment, Amber. It’s getting colder in here. Well, my boobs are. But down there the ‘warmers’ still seems to be working. MMM. Do the thingies move faster if you dial the remote up higher than the ‘three’ setting? Is this feedback helpful for you all?”

Amy looked at Ken who was checking her out. First up top and then between her legs as he yanked off her shorts.

“I guess you win the bet, brainiac. This is working just as you said.” Amy giggled as she started rotating her hips.

“Yup. And I get to third base.” Ken giggled as he stroked the front of his jeans.

“You asshole! The bet was for second base! Oh, hell third base sounds okay I guess. Hey, Ms. Davis, when these nodule thingies get wet, it’s not short circuiting the panty, is it?”

“No honey. I’m soaked and the magic beans or whatever you call them are still working their magic. You guys should sell these. You’d make a mint! I’m guessing you have another Gold Medal this year. Look at what you kids have done to me!”

Amber and Jaden started massaging their teacher’s tits. “We need to see if your pretty boobs are warm at all. Otherwise our project would be a failure. What do you think, Jaden? Is your side feeling warm?”

“Not so much warm as…very soft,” he responded as one hand was rubbing her boob and the other was rubbing the front of his pants.

Ms. Davis said, “Hey, weren’t you going to adjust those bra straps? Amber! Let go of me and work on that bra. What did you do with it? Oh, there it is, on the floor. Hehe. Oh, well. In for a dime, in for a dollar, I suppose.” Her voice still sounded as if she was hypnotized or in a trance as she leaned back on her elbows.

Amy did the same. With that she lifted her ass off the table allowing Ken to yank her panties down.

Ken threw Amy’s panties over his shoulder and grabbed her hips and scooted her to the edge of the table. He looked down at her bald pussy admiringly as he unzipped himself.

Amy smiled at him and said, “Fuck third base. Go ahead and hit a home run with your bat. Let me see how big it is.”

Colleen exclaimed, “Amy! Don’t use the ‘F’ word!”

Jaden seeing what Ken was doing unzipped himself and pulled out his average sized cock. Giggling he picked up Amber’s bra from the floor and hung one of the straps on his erection. “If either of you want the bra, you’ll have to take it from me.”

Amber smiled at their research subject and pinched both of her nipples playfully as she said “I don’t want it. What about you Ms. D?”

Ms. Davis said, “Give me that thing! My chest is getting cold!” She reached over and grabbed Jaden’s cock in her fist, pretending to be interested in the bra hanging there.

Ken giggled at what was going on with them as he lined his released prick up to Amy’s pussy. “Amber, you heard your teacher. Keep her boobs warm. Don’t pinch them! Grab those hooters!”

Davis shook her head. “No, your hands are cold, too. Maybe your mouth. Oh, my! What am I saying? It’s like I’m drunk or something!”

As Amber eagerly bent toward her tit, Jaden said; “Ms. D…is that a tattoo sticking out of your pantie there on your hip? Let me see…” He yanked at her panties hungrily.

She let go of his stiff dick long enough to raise up off the table and let him pull down one side of her panties. She grabbed to cover her pussy. “I can’t let you see down there too far! What kind of teacher do you think I am anyway? Besides, I want to keep feeling whatever these warmer things are doing to me. Christ, it’s like foreplay from my husband! Atta girl Amber. Just like I tell my husband, ’suck but don’t bite’.”

Jaden eyed the quarter sized tattoo at her hip. “Hehe, is that a beaver?”

Through moans, as Amber was sucking her tit almost all the way in her mouth, she answered; “Yeah, I got my teaching degree from Oregon State University. The beaver is our mascot. He’s a cute little thing, isn’t he?” Her hand was back on his cock and started to jack him off.

“Yeah it’s cute but I want to see the real beaver in there!”

“Oh, that’s such an antiquated expression. Where did you even hear it? They don’t look like that anymore.”

“Prove it”, yelled Ken. He was all the way in Amy’s ‘beaver’, grunting in time to his rapidly increasing penetrations.

Colleen seemed interested in what Ken and Amy were up to before she realized what Amber and Jaden were doing. “Oh, just take my word for it. Hey, you two! Quit tugging on these experimental panties! Wouldn’t ripping them invalidate your experiment? Plus, it feels so damn good. I’m not sure I want it to stop. Why aren’t you guys taking notes?”

Amber and Jaden pushed their teacher back flat on the table which gave them a better chance to get her naked. Her pert breasts jiggling as she lay back hard. They were both giggling as they got the panties down her legs and while she kicked her legs in mild protest the kids got them off.

As if coming down from a high, Ms. Davis went limp and tried to collect her thoughts as to what just happened. In her relaxed state they were able to easily spread her legs apart and get a good look at her naked body.

“Well, you’re right, I guess. The ‘beaver’ slang might not be appropriate. But I can see where the ‘taco’ reference comes from.”

Amber was admiring her teacher’s sexy body and started to rub Collen’s inner thigh as she bent for a closer look. Jaden dropped his pants and boxers and was scooting around to get between her legs for a better look. He looked ridiculous with his pants around his ankles and the bra swinging from it’s perch on his hard cock.

Amber covered her teacher’s crotch protectively with her hand and said, “Don’t you dare do anything to her, nerd! Or she’ll stop helping us.”

Slowly Ms. Davis was coming out of whatever orgasmic trance she was in. She was about to protest what had gone on when she looked to her right and saw Ken screwing little Amy right next to her.

She reached out her hand to grab Amy’s hand in support and said, “Ken, stop. This has gone too far.”

Amy grabbed her teacher’s hand but said, “Stay out of it, bitch. He’s doing just fine.”

At that very second, Amber’s middle finger curled up and easily slipped into the older woman’s wet slit. Davis tried to pull her hand away from Amy’s grasp in order to stop Amber but Amy intertwined her fingers and wouldn’t let her go. Jaden saw what Amy was trying to do so he pinned Colleen’s other hand at her side.

Amber wasted no time in taking advantage as she slipped another finger inside Ms. Davis’ pussy and started to pump in and out. She had assertively pushed past Jaden to get between Colleen’s thighs in order to get a better angle as she finger fucked her teacher.

Jaden at first protested but saw another opportunity and reached around Amber and started to unbutton her blouse as she bent forward. Realizing there was no protest forthcoming, once he got her blouse unbuttoned, he moved down to her jeans. Unbuttoning them quickly, once the zipper was down it was easy to shimmy the jeans over her hips and down to her feet. He admired how he also got her panties down at the same time. Her tight ass and the back of her pussy visible to his hungry gaze. He knew an opportunity when he saw one and unhooked her bra. Her big tits jiggled under her as she bent forward.

Now that Ms. Davis’ one hand was free, Jaden expected her to force Amber to stop. However Colleen used it to start to massage her own clit, making sure not to disturb what Amber was doing about an inch below her fingers. “Jesus! How could something so wrong feel so right?”

Ken exclaimed, “Oh, God! I’m cumming! You can’t call me a virgin any more, Amy!”

As Jaden entered Amber from behind in doggie style he yelled, “Me neither! Fuck, this project is an unqualified success! Even if we can’t enter this in the regionals!”

“I told you guys not to say ‘fuck’ in front of your teacher! I know what he’s doing to you Amber but don’t you dare stop! Good Lord, your fingers feel good!”

Ken pulled his cock out of Amy and walked over to Ms. Davis, his softening prick glistening with Amy’s love juices. “Let me feel these titties up and see what all the fuss is about.”

“Well, I’m not as big as Amber here but something tells me you’ll like them. Hey! Who said you could suck on that? You shouldn’t still be horny!”

Amber pulled her fingers out of the older woman’s gaping wet pussy and started lapping up her juices coming out of it. “mmm. So nice! And look at the puddle you made on the desk here!”

“Jesus, how did you learn to do this so well at such a young age!” Colleen said as she lay back to enjoy getting tongued. Ken and Amy came up on both sides of her and started grabbing, squeezing and pinching her erect nipples. With her hands free Davis reached over to both sides and grabbed Ken’s dick in one hand and started rubbing between Amy’s legs with the other. All the while, Amber was thrusting tongue into her honey pot…or were the ‘thrusts’ due to Jaden fucking her hard? She wasn’t sure.

The four kids were pretty sure Ms. Davis was close to an orgasm. Jaden decided that he’d have other opportunities in his young life to screw babes his own age so he pulled out of Amber with a ‘plop’. He grabbed the tail of her loose blouse in the back and yanked her face away from Colleen’s pussy. As she stumbled backward he walked up between his teacher’s thighs and their ‘guinea pig’ couldn’t help but laugh when she glanced down toward the end of the work table and saw that Jaden still had the bra hanging off his cock.

“What are you laughing at? You don’t think my dick is good enough for you? Well, we’ll see about that!”

“Oh, no…sorry. I was okay with a little playing but there’s no way I’m letting…”

As if he didn’t hear her, Jaden stuffed his hard prick in her wet slit. At the same time Amy and Ken decided that they could both suck on her soft tits without banging their heads together.

“Good God, how did you get that thing in there so fast! Seriously, this is wrong, okay? Oh, Jesus!”

He was working his virgin dick in and out of her deeper with every thrust which made his balls slap against her ass. He focused on the light brown tuft of pubic hair in the shape of a heart above her pussy as he grabbed the back of her thighs just below her knees and pulled her legs apart wider. He had seen a guy do that on one of the porn videos he watched for ‘research’.

Amber was frustrated from the sudden lack of attention and hungrily grabbed for Jaden’s ball sack while he was humping his chemistry teacher. She giggled when she felt the bra dangling from the base of his cock even while he was busy fucking. So she grabbed the end of the bra and yanked it up between his legs. The end of the bra strap riding up his ball sack between his gonads.

“Kee-rist! Where’d you learn to fuck so good? Keep drilling me with that thing!”

All four of them at once exclaimed a chorus of fake invective with some form of “Hey, you said we couldn’t say ‘fuck’ and now you’re saying it!” After which Ken and Amy resumed sucking Colleen’s tits.

Amber noticed that nodules in the bra cups were still breathing in and out. Jaden had dropped the remote control when he started undressing there subject. She had a great idea since she hadn’t climaxed from Jaden and was jealous of the attention her teacher was getting. She stuck her index finger into the tip of the bra cup. The tip of her finger could feel the motion of the pods moving in and out around it. With her other hand she spread Jaden’s ass cheek to one side and pushed the tip of Amber’s bra cup up his ass!

She foolishly thought this would break his concentration and get him to pull out of Ms. Davis’ pussy so she could go back to sucking it.

She miscalculated.

“Oh, my God! Those pods are up my ass! Jesus, that feels good!” Jaden screamed as his rhythm picked up.

“Don’t you dare cum in me! What if my husband wants me when I get home before I have a chance to shower? You fucking kids are going to get me in so much trouble! Gawd, you’re sucking my tits so good! First time I’ve had two sucked at once since my bachelorette party! God damn! Don’t bite, Ken!”

“AAAAGGGHHH!!!”

“Jesus! What a load! How much jizz are you putting in me?”

As he pulled out of her, the room was full of five people breathing heavily. Or was it six?

Ken looked toward the back of the room and shouted toward an industrial rack of various robotics paraphernalia and shouted, “Jorge, did you get all that?”

They all heard Jorge’s voice from behind the rack, “Si, Ken. Good thing you finished when you did, the batteries in the camcorder are about to run out.”
