Underwear Exploration in Alphys' Class

1.

Class was over and the students had all headed out - except for one bluebird, and his teacher.

Professor Alphys noticed something different about the bluebird, but wasn't quite sure how to say it. "Uh, hey there Berdly..." the big yellow lizard spoke from behind her desk. "Mind if I ask you something?" 

Just as he'd finished packing things away in his backpack, he stood up out of his seat and nodded, "Sure, what is it?"

It was an awkward topic to bring up, but... she went ahead and asked anyway, "I noticed you're wearing pants to school these days." That was a normal thing, sure, but not for him. Some students didn't really seem to need to wear them, or couldn't! "What's with the change? I hope nobody teased you about it."

Berdly frowned a bit, it was a weird topic for him too! "Oh, yeah, kinda... I mean, I don't need to wear them! But, people kept making me feel weird about it, so, whatever."

"Awww..." she was afraid of that. "Well, hey. Do what you want! Pants or no pants, you're welcome to be yourself in my classroom." 

"Thanks!" He brightened up a bit, "I did try going inbetween for a bit... but uh, apparently wearing JUST your underpants to school is like, the WORST idea!" He laughed a bit. Most students would kind of know not to wear their underpants out in public and act like it was normal. Berdly was... a little weird, sometimes. 

Alphys blinked in shock, but she remembered that day. "I'm surprised you survived a day of school like that." She'd die of embarrassment in that case!

"I know, right? I didn't think it would be so bad!" He chuckled happily, despite all the bad memories, "Ah well. I won't be doing that again."

Alphys was starting to have some weird thoughts about the bird walking around in just a pair of briefs. It was... silly? Maybe there was something appealing about it... "You won't?" She almost sounded disappointed. "Not even for extra credit?"

Berdly blinked, and stared blankly at his teacher. "What? Really?" She had to be joking... besides, "I already have the highest grade in class, don't I? I don't really need extra credit... even if that'd be, sort of easy."

Alphys lowered her eyelids, feeling a little sly for once. "I mean, you do. But you never know, you could try and get over 100% if you wanted." Was she teasing him? Maybe this joke was going too far. If they kept talking like this, he might actually do it! And Alphys had to think about if she really wanted that or not.

"All I have to do is show you my underwear??" Berdly asked, he was considering it too! Though, he knew maybe it wasn't appropriate to do with a teacher... but he'd done it before in school anyway! Pants, no pants, underwear... he wouldn't want to do a whole day in underwear again... but if he just had to show her what he was wearing under his pants for a few seconds or minutes? He'd do that!

"Uh, well..." Alphys tapped her claws together. Uh oh. Was this... happening? He was seriously asking what to do to get a better grade! Wouldn't it make her kind of weird to ask that of a student? Not like she'd want to see everyone's underwear in class! Maybe it was best to tell him it was a joke before it got out of hand.

"Here." The blue bird reached for his shorts, slipping his feathery fingers inside, and pushed them down to his yellow ankles. Underneath, he had on a pair of white briefs that clung tight to his underside. He still had on his dark-grey undershirt and the usual white top buttoned over it. He folded his arms, and closed his eyes. He seemed very matter-of-factly about this. He just took off his pants, showed his underwear, and now she could see it. Nothing funny or weird or crazy, just showing off your clothes to someone. Nothing too bad about that, right?

"Oh gosh..." poor Alphys. She hadn't stopped it, and not here they were. "Uhh...!" She initially looked away... but, eventually turned her head to see. Her eyes went wide, staring at his little white briefs. The edges had grey around them, and there were some straps down the center. She didn't really get how those worked, but she knew they were for... pulling your, erm, parts out of? She wasn't sure about looking close for a bulge or anything, she felt more like she shouldn't look at all! "Ah, y-yep! Yeah, that's... your underwear! Totally." She covered her eyes, feeling her cheeks heating up. This was embarrassing!

"It sure is!" Berdly proudly exclaimed, before his fears started seeping in. "Uh... are you okay?" He noticed her strange reaction. Was she embarrassed looking at him? She's the one that asked! Or... was something wrong with him? "Is that it? Did I... pass?"

Alphys slowly spread her fingers to look at him, bravely showing his cute little undies to her, all just to excel in scholastics. "You're fine! Haha, I was just kinda joking, I'm sorry... I didn't think you'd really do it!" But, she knew that'd be disappointing to hear. "Heh, don't worry, I'll still boost your grade! Ugh, I feel bad... y-you look fine! Thanks, uh..." the big nerdy lizard was feeling really awkward now.

Berdly sat his underwear-clad butt on his desk - his legs open enough to show his underwear-covered crotch. The material bunched up a little. He idly kicked his legs, wondering what happened next. "Oh, I see... woops." He looked down at his bare legs, "Sorry..." 

Alphys shook her head, "No no! It looks cute!" She laughed, trying to look at him, despite how weird it made her feel, "You did a good job of it... I uh, actually haven't seen many guys in their underwear before. Well, like, not in person and stuff!" She took advantage of the opportunity and stared a little more, "Um, it's neat! I mean, girls are neat too... uh, but yeah, for a not-girl, you... look cute?"

Berdly started blushing. He didn't get the weird way she phrased it, but he got one thing! "You think I look cute?" In his underpants, no less! "Wow, well that's flattering." 

Alphys was just glad he didn't feel bad, "Y-yeah!" And she felt like she was just joking or teasing around, but she couldn't help but add onto it, "How much credit for you to take off the shirt?"

The bird's beak dropped! She was flirting with him more?? Well... he wasn't sure if it was flirting before... but it seemed like it now! He went ahead and unbuttoned the white shirt he had over his other one... slipping it off slowly, and letting it fall to the back of his seat. Now he was sitting on a desk, in just his briefs and near-black shirt! "The first one's free..." he tried acting smooth, but, he felt about as nervous as she did! He was the one undressing in class... what if Toriel or someone else came in and saw him half-way undressed?? 

Alphys should have been the one more concerned with that, having one of her students undressed in front of her. But she didn't think anyone would come in... and actually, if this was going on, maybe it was best for her to get up and lock the door. "You don't mind if I keep this thing shut, do you?" She asked him as she got up to do exactly that.

"And have someone ruin our extra credit moment?" He laughed, "G-go ahead!" He smiled nervously.

As a loud click of the door's lock was heard... they both figured this meant it was serious!

2.

Berdly crossed his legs over his desk as Alphys got back to her seat. They both felt really weird about this... she was asking him to undress for extra credit, and he was actually doing it! What started as an awkward talk and joke ended up actually happening... but for these two shy nerds, it sorta made sense it would work out that way.

"So..." Berdly hopped off the desk, standing in front of the classroom in just his grey shirt and briefs. He raised his wings up and stretched, making it easy to see the waistband of his underwear. Alphys couldn't take her eyes off of it... it was interesting! The fabric looked soft, his feathers looked like they were nice to pet and feel through... she kind of wanted to feel it all herself!

"Ummm..." she thought about asking, "You look really nice and soft? I think?" She laughed nervously. Berdly blushed - of course he was soft! ...Did, did she mean his penis? Or his body? Well... everything was! His feathers were fine and clean, smooth and very nice to feel - he thought. His undies were also just... normal stretch fabric and stuff? Soft enough for him? And well, yeah! He wasn't erect or anything. His bird penis was soft and flaccid, bunched up in his briefs... so, she was right about all that. She wasn't going to ask him to get hard for her or anything was she? He was already feeling so nervous, he was more like... the opposite of hard right now. Almost scared soft! "Well, I wonder... if your backside looks as soft?" Maybe it'd be better for her to see that than ask about touching right away!

Berdly laughed, "Y-you wanna see my butt??" He laughed, "Huh..." He started to turn a little. "I mean, you can..." he looked at her with his back turned, "Kind of an odd request, I mean... not like you can do much to my butt anyway, right?" Gosh, what an odd conversation. He was speaking in terms of sexual situations, but with his teacher! And a girl, which well, that shouldn't really change anything, but he was still used to the idea of guys being the ones that were dominant and impressive during sex. If anything, he'd be the one wanting to know how soft or attractive someone's butt was, right? Not like she was gonna be, uh, doing anything to his! "R-right...?" Then again, he realized, anyone can like anything! That meant everyone can like butts, and like staring at them, seeing them, feeling them... no matter what they did with them! He did often brag about being impressive and appealing all the time, something he was trying to cut down on and improve... but, someone actually being into him and wanting to see his feathery bird butt?? That was great! It was kind of nice someone was into it... but it did make him nervous, wonder what exactly Professor Alphys WOULD do with his butt if she had the chance... but hey, he was just showing off his underpants. He could always say no if something too weird for him came up.

"Don't worry Berdly." Alphys chuckled, "Uh, your butt is safe from me!" Gosh, she really had to tell him that?? "I mean... you know, we're teacher and student!" She didn't want to admit they were talking about sexual things, but... "I mean, there are things that, um, people can use to... do things..." No no no no, she wasn't going to turn this into a lesson on sexual education. "D-don't worry about it! I'm just... looking!" She smiled, seeing those tight briefs wrapped around his blue bird butt, with Berdly looking a little more worried over his shoulder - eyebrows curved up, beak hanging open a little... this didn't seem good!

Alphys tapped her claws together, "Though uh, you know... I do kinda... want to just... touch it..." she admitted. He was clearly nervous and worried about her doing something to him, but she didn't plan on having sex with him or anything like that! Heck, she didn't even want to see him in his underwear but, she was starting to like it now... "If you're too nervous it's okay, I don't want to make you scared."

Berdly turned around, almost as if to protect his butt! He closed his legs tightly together, making his underwear bulge pop out a bit. "Huh? Oh... me? Scared? Ha! I never get scared, come on. I'm just... hanging out, in my underwear! Hahahaha. No one's dumb enough to do that in school! But, one bird's brave enough to do it, and that's me!" He got into a heroic pose, putting on foot up on his desk, clearing showing off his tight briefs some more. "You can look all you want! Heck, you can... probably touch too..." his excited tone started sounding nervous again. "Umm... just... be gentle?" He almost sounded sad, like she could be too much! She was big, powerful, and older, while he was a fairly skinny bird that was bullied kind of often... he wasn't really a sexual expert or anything either. He just knew the basics were okay, kinda, maybe... not like he was experienced all that much.

Alphys thought this seemed kind of cute, having a guy for once seem kind of helpless and submissive, or worried. Usually she'd be worried! She was SO scared of sex or anything sexual! She could handle watching some hentai, and weird stuff... but doing anything real made her worry about the same thing, being pulled into more than she could really handle. "Ah, Berdly, don't worry. I'm nervous about that stuff too." She got up and walked around her desk, "It's exciting to think about, but, scary to actually do, I think." She then smiled as she looked up and down his body, "That's why just looking and touching is nice. It's not too much. And uh, I mean, if this wasn't just some extra credit thing... I'd say we can always work our way up to stuff if it's more than that." She smiled sweetly towards him. 

"Ah, well... thanks!" He started to smile brightly again, "Well... I have been in my underwear for a while, and you have seen a lot of it..." he tapped on his beak, "I guess if you, really want to touch it a little or something, we can?" He grinned awkwardly, "I'll just say if it's a lot, but... uh, I think it'll be okay!" 

Alphys nodded, spreading her arms, and gently pulling him into a hug. "Heh, thanks!" She pat along his back gently, "Hugs are okay, r-right?"

Berdly laughed, spreading his blue wings and hugging around her big round backside too. "Of course! Ha, I can handle those. Heck, I kind of even like them... I uh, don't really, hug much... but I'd like to!" 

The big yellow lizard lifted him up with a laugh, nodding. "Oh! Well... cool! I'm weird with hugging... I get kinda nervous about it... but, it does feel nice." She left go a little, her claw rubbing along one of his wings, "Heh, your feathers do feel really nice too..." she gently stroked them back and forth.

Just having someone feel and rub along his wings was a pleasant feeling. It was still odd that it was Alphys doing it, but tough lizard scales were far different from fluffy bird feathers. "Ha, it's okay Alphys. Uh. Feel all you like! I don't mind."

The two just stayed close for a bit as she gently rubbed and felt along his feathery arms and wings as they warmed up to each other. Both shy nerds were starting to feel okay and comfortable with each other. It'd probably been over half an hour since all this started...

"Uh, oh, are you going to get in trouble if you stay longer?" Alphys looked up at the clock.

"No." Berdly replied, "No one'll notice if I'm gone for a while." He sounded almost sad about it. "What about you? How long do teachers stay in class after we all leave?"

"Too long." She gently squeezed him, ready to do a little more...

"So how much extra credit is this earning me anyway?" Berdly asked, standing in front of Alphys in the empty classroom in just a dark shirt and white briefs. 

"I dunno really," she admitted, "I just enter in some numbers that raise your total class points, I'll just... add whatever seems right for what we do? I don't want it to be too obvious... but, you won't have less than an A so, don't worry!"

"I already have an A+ in class!" Berdly laughed, "But whatever, we'll see~" He looked down at his belly and underwear, "So uh... did you, wanna touch my underwear?"

Alphys turned red, her eyes wide and pupils small, being asked finally to do that. "Oh, right! I... yeah, I kinda do."

The lizard crouched down in front of Berdly's crotch, her face was inches away from the front of his underpants. They'd been together like this for a while, so he was just all normal down there again. She could see a few bumps and things, enough to figure out and see. She could probably guess which bulge was from his penis, and the way the bottom kinda curved, those seemed like his balls... she didn't know where to start! So she just poked around at one of his balls from the side, making sure the pointy tip of her claw didn't touch it, using the flatter sorta side instead. "Huh... hehe." She smiled a little. She pushed her finger against it more - his whole bulge shifting over with her finger - and as she moved her hand back, it all sorta slowly sank back down in position. "Weird..."

She then reached up to sorta gently squeeze her fingers around where she thought his penis was. It was soft and squishy, and honkable! It was kinda fun to just touch and play with in there. Even though she was a lil more into the ladies... maybe she'd try more ladies with penises sometime! Or heck, maybe she'd just try and do something like this with Berdly again... or just imagine this, since it was maybe a little risky for students and teachers to do this. Even as adults there'd be worry about bias, and she was actually improving his grade for all this... uh oh, maybe it wasn't good to be doing this as they were, but uh, e-everyone makes mistakes??

She tried to focus on playing with his penis through his undies instead. Alphys was able to swish it over to the side sometimes, and feel its flaccid size. She even moved it so it was flopped upward, pointing to the top near his waistband! It was actually pretty fun. It almost made her think about slipping it out... She tried not to worry about that though. She jiggled around his balls for a bit, before reaching to his hips, gently holding and squeezing them... it felt nice! She wasn't sure what else she could do to his front... but then she realized, it was odd... but.

"Sniff sniff..." she leaned her nose in, innocently sniffing his crotch for a moment. She looked up at him, feeling kind of weird about it.

"Haha." He looked down, it kind of tickled him. "Are you uh, sniffing me?"

"...Kinda." She felt guilty, and pushed her snout against his crotch more - the little bumps inside softly squishing against her nose as she pushed her face in close and breathed in. It was weird! But kind of nice feeling his crotch squish against her face. It was warm and cozy. And with his underwear on, it was like, not exactly touching her... so it wasn't as naughty as it could be, but it was kind of nice! Even without breathing in his birdy scent, she enjoyed just lifting her snout up and down, feeling his genitals squish up and down on her, bunching up close together, and loosely hanging on top of her nose. It was a weird sensation... but, she really really liked it. "Uh, heh... thanks for letting me do that. It was... nice?" Weird? I dunno." 

"Better my front than my butt!" He laughed, not really getting why someone'd want to sniff someone else's parts... despite being a gamer, he did bathe! So he should smell just fine... but something about it felt weird.

Alphys pushed her nose further between his legs, with the tip of her snout wiggling close against Berdly's buttcheeks. He squeaked and jumped up a little at her ticklish nose back there, "H-hey!"

The lizard lady laughed and retreated her snout from between his legs. "Heh heh! Sorry..." she smiled. Her face still felt warm from having him placed on top of her... she almost thought it'd be nicer in the winter. A cold day indoors or outside, and feeling someone's warm ballsac on her face... oh no! Was this making her weird? Er, weirder?? Maybe she'd start having new fantasies based on her experiences...

Berdly at least enjoyed having someone touch against his parts! The underwear didn't stop too much from feeling nice. He could feel her ticklish breath seep through the fabric of his undies and warm up his genitals. They still felt touched, and pushed around, and played with inside there. He wasn't gonna get an underwear fetish, was her? Then again, maybe he'd see sometime how all this felt without underwear! Well, if he'd even get that lucky again. Heck, maybe he should... try and make that happen now! Well, he thought about it, but he felt something wet rub against the front of his undies. He looked down and... Alphys was licking it?? "Woah!" He gasped, trying not to be too loud. She paused, blinking for a moment, before resuming. She was licking his underwear bulge from the outside... and it still felt nice? It was weird to lick underwear... but, she liked it so much, she did it anyway? Berdly laughed a little. She knew she could just pull his undies down, or open the hole if she wanted to, right? This was silly! But... it was good. He wouldn't complain! Maybe she preferred this in underwear? Or maybe they were both a little scared of going further... licking your students underpants was weird, and well, still probably sexual, but it wasn't straight up oral or anything! It was just some kind of, nice tease, that still felt pleasant. Berdly felt his penis twitch inside, it clearly still enjoyed her tongue and breath slurping up against it, even with cloth in the way...

"Ah... oh gosh..." Alphys felt herself a little turned on from all this. She wanted to keep licking and rubbing herself against him in his cute undies! If she wasn't so nervous, she'd peel them right off of him and go further, but... maybe they'd save that for a sequel! Er, or for another time, rather.

"Can um..." she looked at him, worried it'd sound weird, "Can I turn you around and see the back?"

Berdly blushed. It was this again... she wanted to see his underwear-butt? He bit his beak, and nodded. He stepped up to her desk, and rested his arms on it, pushing his underwear butt out a little, "Uh, like this?" He swayed his butt a little for her.

The over-excited nerd nodded, blushing as she crawled up to it, "Y-yeah... heh heh..." She reached up and held around his hips with her claws, staring at his butt, almost drooling over it.

"J-just uh, please nothing too weird! Or ask if it's more than um, touching or whatever?" He winced, hoping that didn't ruin the mood for her. "I-imagine all you want, though!" He wouldn't wanna stop her from having a good time though!

"Don't worry, haha, I'm uh, kinda scared too. I don't know much about butts!" She pressed her snout against his buttcheeks, "But uh, I um, I'm really excited and stuff I think, so... I'm learnin' now!" She nuzzled and kissed along the undies covering his butt. Her snout raised up and nuzzled around the blue feathers of his tail that poked out over the top. She ruffled them gently with her nose, kinda like a bouquet of flowers, but or uh, a bouquet of feathers in this case! She hugged her arms around his lower half, and turned her cheek to her buttcheeks, and just rested her head there for a moment. Like a little set of butt pillows, she enjoyed just... resting her head against them for a bit. It was cozy! She always thought it'd be too weird to do this with someone, and she didn't really ever see others mention it much, but butts felt nice to just snuggle and rest on too. And this seemed like a rare opportunity to just enjoy it for that. "Ahhh..." she sighed happily, "thanks. I'm being weird but... I like all this."

Berdly cackled, "I can tell! Well hey, that wasn't so bad." He smiled with relief, "If you ever need to take a little nap at school, you can use my butt, if you ever want to... it is full of feathers!" he joked around.

"Ha! Yeah... I mean... maybe! I'd get in trouble butt..." Alphys lifted her head, and gave it another kiss, before her claws traveled inward and landed with one on each cheek. She spread her fingers out and pushed up against his tushie. "Heh, it's cute..." she hummed, enjoying how soft and squishy his butt was, pressing her hands against each cheek, before giving a tight squeeze, catching it all in her fingers.

"Gah!" Berdly yelped, a little surprised... but it felt nice! "Heh. Wow! Someone's grabby." He didn't want her to feel bad hearing that though, "Oops, I mean, it's fine. I'm glad you like it!" He shook his butt proudly left and right - gosh, how embarrassing... if anyone caught him doing that, he'd be humiliated. Wiggling around in his underpants, in the front of the class? Thank goodness only Alphys was here to see it. And she liked it too! He was still amazed.

"Alright..." she sighed, sounding like she'd though of everything she wanted to do back there. "Well, actually... two little things... Um. Berdly..." she sounded a little weird, "Can I give you... just one weird touch... somewhere..."

Berdly blinked, "I have a feeling I know where." And, not denying her the opportunity, he chirped as he felt her thick clawed finger press against a very sensitive area in the back! "A-ah!"

Alphys laughed to herself, a bit in disbelief she did that... but, she couldn't help but be slightly curious! "Heh heh heh, don't worry, I'm just teasing..." Poor guy~ Though, maybe she'd have fun trying stuff more like that some other time! "Alright, one more thing..." She reached up around his waistband, waiting a moment. "Umm... can I... pull these down for just a second to see?"

Berdly felt his tummy tense up. He was really gonna... let her see his naked butt? His bare bird bottom? He worried, maybe it'd lead to more nudity! Or, make his sensitive spot even more vulnerable... but, he shook his head. "You can see my butt if you really think you'll like it that much, Alphys~" He laughed, sounding confident despite how nervous he seemed!

"A-alright!" She whined, a little excited, "Naked butt time...!" She huffed, before pulling his underwear down, seeing two big round blue cheeks in front of her face! She could see all those cute, puffy feathers poking out - flattened a lil from the underwear, but also squeezed and rubbed around by her claws earlier... she smiled simply at it. Enjoying the view... "You know, I guess I could see this all the time if you ever get less shy about walking around bottomless. I never really uh, thought much about it, or thought it seemed too butt-like before, but... seeing it now..."

Berdly scoffed a bit, "Well I wear long shirts! They cover my crotch and butt just fine, usually! It's different if it's all out of the way and showing..." he thought for a moment, "But heh, I mean, if you want, maybe I will go back to not wearing pants... it could be fun to show you once in a while... just for fun."

Alphys giggled, could she really trust him to be subtle or secretive about all this? "Uh, hmm... well, I dunno... you'd have to be careful... I do like seeing it though!"

"I'm gonna tease you just a bit more..." Berdly thought, as he shuffled out of his underwear. They went all the way down to his little yellow feet! 

"Huh!?" Alphys gasped, uh oh! 

"Yeah." He stepped out of them, walking around the front of the classroom with only his light-black shirt on, "I'm gonna walk around the classroom without pants on!" Alphys gasped, watching him playfully strut around, showing his naked blue birdy buttcheeks! He walked around the desks - some obscuring the view a bit, but as he reached the back, he covered his crotch, "Well, can't give away the goods just yet..." Alphys was nervous about seeing them, so it was okay! It did mean he was touching them in his wing though... and he looked very silly. She just laughed as he reached the other corner of the room. 

"But this isn't naked enough! I still have my shirt on..." he noted, before reaching up, and pulling it off. He closed his legs together and bend over a bit, so his penis and balls were all tucked away between them. He then stood up mostly-straight and tossed her his shirt, "There! See? I'm naked in class! I'm totally nude in here! And you'll be teaching in it tomorrow!" His voice was a little more loud than she'd like.

"G-gosh...!" She stared - she did think it was cute how he closed his legs with his bits tucked away in there. They were all safely hidden. It was like seeing someone naked but without their parts showing... it was neat! But, as he started walking again, he covered up his genitals, teasing them behind just a few feathers as he reached the front corner again, and walked up to Alphys.

"Ahh, heh heh, there we go. That was pretty fun! Really naughty to do... but we did it~" Well, Berdly did it. But whatever! "Care to put my undies back on?" He reached out one of his yellow talons, wiggling his bare toes in front of her. She laughed and nodded, agreeing. She slipped his underwear back onto one ankle, and then around the other as he lifted it up. Here he was, naked, with undies around his legs, barely covering up his nakie parts in front of his teacher's face... but she grabbed them, and pulled them up to his hips, his fwingers going inside his underpants before letting go, and getting them all on! For a second, Alphys could have sworn she'd seen something... but, he was all back in his underwear again. And nothing more. 

"So..." He stepped up to her, pressing his squishy underwear front up against her nose, "What next?" ...He quickly chirped, "Well, unless you're all done and wanna stop or anything..." he sounded concerned, "I uh, I do try not to be as annoying and obnoxious and pushy as I used to be..." Almost out of nowhere, his considerate side popped up! "It was nice of you to do this all with me... um, of course, whenever you don't wanna, just say so! But... if you wanna do more, I wanna do more too..." he grinned, cheeks turning pink as he left it up to her.

Alphys smiled - how sweet! He was a big pain before, but after some recent events, it felt like he'd toned himself down... slightly. "Aw, heh, that's considerate of you, Berdly, thanks."

The bird nodded, proud of himself, but not too proud! Just... a little. Some things don't change completely~

"...Yeah.... there's a little more I wanna do with you..." She took a deep breath, everything stepping up one bit at a time...

Alphys grinned, reaching down and tugging off her own pants, standing up in front of Berdly with her green coat and shirt on, her red school teacher tie, and her pants down around her ankles. She had pink panties on her fat little figure.

"Um, Alphys!" Berdly blushed, looking down below her chubby belly, and between her big thighs, right to the little pink triangle of cloth between her legs. "I didn't think I'd be seeing you in your underwear..."

Alphys froze. Oh no! She didn't think to ask! Was that okay? Did she got too far or weird him out!? "Oh! Uh! S-sorry! Um, should I... put my pants back on??" She covered her chubby little crotch in her claws, closing her legs together shyly, "Sorry, I uh, I guess I got all heated up, I didn't think to ask!"

Berdly laughed, shaking his head, "Oh, no it's fine. I just, I'm surprised! It's a little naughtier... not just me showing off, but seeing my teacher take her pants off too. Ha!" He noticed how shy and nervous she was, "I think it's... attractive. You're pretty cute, teach!" He perked up with confidence, "Come on, I'm in my undies, it's okay for you to be in yours. It's just underwear! We're not naked."

Alphys felt her face heating up, nodding, putting her hands behind her back as she curled her legs in, toes rubbing at the ground shyly as she avoided eye contact. "I-i-if you say so...!"

Berdly nodded, "So! Is there a reason why you're in your underwear?"

"There is..." she nodded, "But, not for what I wanna do next... Can you um, sit on my desk again?"

Berdly hopped on up in his underpants, legs dangling off the edge once again. "Oh yeah, sure! But... Alphys, you know, you're gonna have my underwear and butt all rubbed into your desk now! So whenever you use your desk, you can just picture my birdy butt on it, heh heh heh."

Alphys blinked. That was a weird thought... whenever she was teaching class normally... she'd remember her own student was up on there with his butt on the table! "I guess so huh... haha." She sat down in front of him, and reached for his talons. "Can I uh, just... play with your talons a little?" She held them in each claw, and stroked gently underneath them. Berdly relaxed and enjoyed the little massage he was getting.

"Sure!" He smiled, not really... sure what she was doing. Was this a foot thing?? Or a massage? He was confused, and watched her just rub along his skinny little legs, and sorta short birdy toes. It felt like just a little massage, which was nice. He curled in his toes a bit, and gave them some wiggles here and there, not quite sure but, just going along with whatever! Heck, it was easy and he didn't mind it, so that was fine!

Alphys on the other hand, had a growing curiosity for these things. She had fun rubbing and playing with each cute avian toe, rubbing down to the nail at the end. It was weird, but she just liked how scaly and yellow birdy legs were? Then again, it was kinda like her own! But, different. But definitely similar to her more reptilian species! It was weird birds had hard scales down here, but then skin everywhere else, and on top of that, feathers instead of fur! What a strange mix of species... but a good strange! 

She brought each foot up to her cheeks, and held them there, softly squished between his talons, and just closing her eyes. Berdly tried to be nice, and pet on her nose for a bit with his foot. He then rubbed along her face with both! Her cheeks, nose, head spikes... and back down to her mouth, where she pulled them up close to kiss and lick softly. "Heh, sorry, I hope this isn't too boring..." She looked up - seeing his small underwear bulge between his legs, "It's a nice view too..." Berdly stared down between his legs, and how Alphys was staring right at it.

"Wow Alphys," Berdly chuckled, "that's my crotch! My jewels! All my stuff's in there. You're staring at it while kissing my birdy feet?" He chuckled playfully, teasing her a bit as she looked and kissed the varying parts of his body. 

"I-I know what it is...!" She huffed, kind of enjoying his teasing! She started to kiss up his little yellow legs, all firm and shiny... up to his knees, where his blue feathers started sprouting... continuing her kisses up his feathery blue thighs, which were ticklish for him - he couldn't help but giggle and wiggle around a little!

"Ahahaha! H-hey!" He closed his legs a little, but then huffed, spreading them out, "I'd say stop it, but... it feels nice..." He didn't know what to do when her head was nestled between his legs, kissing his feathery body... so he just pet on top of her head and hoped that worked. It seemed like the thing to do! Her snout once again poked against his privates, nuzzling his bulge, kissing and sniffing it, licking it again like she had earlier - it felt funny and Berdly liked it! He raised his legs over her shoulders as she kissed and admired his silly undies, before moving up to his tummy, kissing his blue belly feathers, lapping them up with her tongue, gradually laying the blue bird boy over her desk. Now he was looking up at her as she leaned over him, a bit big and imposing! "Oh gee..." things felt kinda serious. It wasn't just posing in his underpants for her... this felt rather... adult!

"S-sorry... I've just been enjoying it." She rubbed along his sides, her belly leaning on top of his crotch, gently squishing up against his underpants. "Any time we need to stop is fine..." 

Berdly moved his legs up, and wrapped them along Alphys' sides and back, "It's fine..." he put his wings up on her shoulders, "I like it..."

Their snout and beak were both just a few inches away as they looked at each other. "Oh no..." they both thought. This felt like when a kiss happened! Right on the... well, not lips... snout? Beak? Whatever!

They both just stared at each other, or looked away sometimes, not sure what to do... Alphys figured she'd make it less worrying, and just nuzzle her snout against his cheek. Whew! Crisis averted! Berdly giggled at the nice nuzzle, and did the same back! Just... nuzzling cheeks together all gentle. But, after a moment... he figured, heck, it was close enough! And he gently pecked his beak against her cheek. "Muah!"

Alphys gasped! "Berdly!" She looked over to him... he... looked cute! He was happy! And he was being nice... he hadn't said anything too dumb or mean all day... and he was even being a bit of a gentleman, and just letting her do what she wanted to make her happy. She realized all this with a smile, and kissed his beak back. "There." 

The blue bird chuckled, nuzzling his beak against her snout affectionately, before closing his eyes, and Alphys doing the same. They just let their pointy yellow mouth-things rub together for a bit in this heated moment on top of the teacher's desk... before their mouths slowly started to open, and they started to kiss.

Berdly's beak clasped around Alphys' open mouth, and they pushed them both close together, kissing and cuddling, enjoying their nervously affectionate, yet happy moment together. They kissed and made out, arms wriggling around each other to cuddle and hold, petting behind one another, making small little noises as their tongues met each other's too. It was nice! Just two sorta-needy little nerds, who slowly warmed up to each other, finally getting to express themselves with someone else. They huffed out of the holes around their snouts as they felt themselves starting to run out of breath... their eyes slowly opened, staring at each other, surprised they did this at all! But here they were. Even if it was naughty and not what they should do... it felt nice! 

Berdly licked at her snout, and Alphys chuckled, before licking back at his. They gave each other a few more slurps, before they were just licking each other's tongues! It wasn't quite making out, it was external... but it was very intimate. Berdly squeezed the chubby nerd tightly in his flimsy legs and wings, pulling her in to hug her tight, and she squeeeeezed him back, just licking each other as a way to express their love. Uh. Well was it love?? It felt right to say in the moment but... maybe it was something else. Could just be horny and heated... maybe just something affectionate. Who knows! But, Alphys wrapped him up in her arms as their licks slowed down, their mouths closed up, and they ended the session in a slightly wet kiss on the lips. (Or well, beak tip and snout tip... whatever!!)

The two just panted, holding each other... staring at each other, Alphys' big tummy going up and down with each breath right up against his undies and feathers.

"I love this..." he smiled, looking up at her.

"It's pretty nice, huh?" she laughed. It was weird... maybe they wouldn't again, but right now? It felt great! They each shared a few more kisses on their snout tips, before getting a moment to just rest and breathe...

6.

After catching their breath from a peaceful moment together, Berdly still laying back on Alphys' desk as the two snuggled belly-to-belly together, Alphys adjusted their bodies so the front of each other's underwear was touching with the other. His little white briefs rubbed in against her pink panties, both of their genitals feeling a little funny, squishing in close together. Alphys was taking a bit of charge here, making sure her crotch was against his. Even through her warm pink panties, she could feel a few little bumps and bulges pressed against her. She could tell the main central member rubbing against her was his penis, and below, his balls wobbled around with warmth, pressing along the bottom of her labia. It was a different feeling, touching his parts, and feeling out what's what, while only using her own parts - and both through two pieces of fabric covering them up!

Meanwhile, Berdly was enjoying a similar experience. Even with some undies in the way, he could feel a chubby pair of lips through her panties. They even opened up a little! And that's around where his penis was rubbing. He... didn't exactly know genitals the best. He wasn't totally aware that he was rubbing against her clitoris a bit, and further down her slit. It's not like he never looked up porn or anything! But, he was far from an expert. But he was glad he could tell what she had, he could tell it was different from his, and it felt nice! Having a bigger girl hump you was... exciting! His legs rubbed around her chubby belly and back, securing his spot, all while she still had on her cute tie and coat, looking rather professional - but if anyone was behind them, they'd see her big yellow butt clad in pink panties, and his own blue bird butt, covered in white briefs, and their crotches snuggling and rubbing together.

"Ahh..." Berdly bit his beak, "Th-this feels... really good..."

Alphys huffed and nodded, it was a lot of physical activity for her! Maybe it'd be best for her to be the one laying down submissively, with someone more fit riding on top of her. But... she was kinda horny for all this, she wanted to do it, and she felt a little safer being in charge. It wasn't exactly sex, or well... it wasn't typical sex! He didn't fit anything in her hole down there, they were just rubbing their clothed crotches together, gasping as their underwear grew a little wet and slightly sticky together... everything was heating up, and turning them both on. It was really weird! But... maybe for two nerdy newbies who were afraid of sex, or maybe just not interested in it... this was a nice way to rub themselves against someone else, and feel cared for too. Alphys did want the best for all her students after all! And Berdly respected his teacher, and anyone smart - so, they at least had a few reasons to care about each other. She was still surprised all this happened just from talking about his pants and making a few jokes, but, it was really nice! 

Alphys continued rubbing until she realized the position was a little tough for her... she could probably end up getting Berdly off if she continued this way... but... maybe there was a way both of them could get off together...

"H-hey Berdly..." she shyly suggested, "I have an idea... is it uh, o-okay if we change positions for a moment?" She sat up, tapping her fingers together.

"Oh~?" Berdly smiled, he looked down and saw a little bump in the front of his underwear throbbing. The tip of his underwear was wet too! He'd obviously leaked a bit of pre-cum from all their rubbing... not enough for him to climax just yet, or maybe he was just enjoying the ride. Alphys looked down and stared at it too, laughing a little from her handiwork. She was surprised she made that happen, and with Berdly of all students, and at her desk at work... but, it happened!

"Y-yeah, uh..." she smiled, "You look nice, by the way." She leaned down and kissed his underwear bulge, right where his penis tip must have been. He chirped in pleasure as she stood up, and lifted him up in her arms, holding him above the ground, his feet not quite reaching the floor, maybe enjoying a little hug together first. He looked tired, but satisfied! Alphys looked exhausted, but still kind of needy... "H-here..." 

She set him down on the ground, turned him around, and hugged behind him. "Alphys...?" Berdly wondered, feeling her belly and underwear rubbing against his butt. He felt kind of funny, having his buttcheeks rubbed around by her tummy, everything was still very warm, soft, and squishy! "You just can't get enough of the bird butt, can you?"

"M-maybe I can't..." she groaned, feeling just a bit needier... but she knew what she wanted to do...

-----

7.

Alphys lowered Berdly onto all fours, in front of her desk, in the middle of the empty classroom.

"Oh boy..." he laughed nervously. She said she wasn't going to do anything too weird to his butt... but here he was, in the receiver position! They did both have underwear on... and it's not like Alphys had a penis? So she couldn't hump him like in the type of hentai they'd both likely seen. He couldn't imagine her pulling out a sex toy from her coat pockets either... s-so what was she planning to do with him like this?

Alphys got onto her knees, and started to crawl up behind Berdly. She put her pink-pantied crotch front right up against his butt. He gave a surprised little, "Ooh..." as he felt her lower lips press warm and chubby against his butt. This was... odd! But nice? She started rubbing her crotch against his butt more... and he rubbed his butt back against her. "Haha, is this what we're doing??" he asked a little in disbelief.

"I-I think so...!" She nodded, leaning over Berdly's backside, getting her hands onto the floor as her belly rested around his tail and lower back. They were simply rubbing their underwear-wearing lower halves up against each other... and it felt great! Alphys got some nice stimulation, she liked feeling his round little butt against her bits, and his ticklish feathers around her tummy. Berdly liked feeling something against his butt, without really having to receive anything just yet! And it even aroused him, being dominated and topped by his own bigger, tubbier, older teacher. She seemed to like him! And she was humping him because she was so attracted to him! Or well, that's what it felt like in the moment anyway. He had fun rubbing back, and he even got a little excited between his legs. The front of his underwear poked out, with a wet tip dripping between his legs. As the two wobbled around, one long little strand of pre-cum dripped out, hanging loose from his bulge, and it swayed around under his belly as she humped his cute little butt! 

"Alphys...!" Berdly whined, surprised, but he was in pleasure! Everything felt nice! Alphys chuckled from above... he was... kinda cute! She kind of just wanted to cuddle and kiss him... so, she decided to be brave and do it! She started by sniffing and nuzzling behind Berdly's neck, which sent a shiver down his spine! "W-WOAH!" He wasn't sure why, but feeling her breath go through his neck feathers made him feel so nice... it was a sensitive area! "Aaaahhh...." he closed his eyes, feeling weak. He started to sink towards the ground, so things started moving! Alphys lowered herself too, wrapping her arms around him, his arms and face by the floor with Alphys laying right on top of him while their butts were still in the air. She kissed the weak little birdy all over his cheeks, along his face, down his neck, snuggling and loving up against him as she humped up against him in her underwear. It was strange, but it was cozy and nice and felt right for them! 

"Good job, Berdly. Just relax..." she nuzzled deeper into his neck feathers as he let out a helpless little squawk! Their needy, feral, animal nature coming out as the two tangled up together, Alphys squishing the thinner birdy in her arms, clutching him close and humping until she felt something about to happen! "Oh... oh no! Oh gosh!" Why was she so surprised? With everything they'd done, and how she was humping her student on the classroom floor... of course she'd end up climaxing soon! It's why she moved him down there, didn't she? "I think I'm gonna... u-ummm...! You know!"

"What is it, Alphys...?" Berdly played dumb, or maybe he was just teasing her. "Tell me what's going on~?" He wiggled his little bird butt under her with a laugh. "You feel alright?"

"Y-YES I DO." She belted out, feeling embarrassed having to say anything out loud, even if she was with someone and doing all this... talking about it was just... embarrassing? Weird?? She didn't know! "I-I think I'm getting close to... y-you know... um, climaxing??" She nuzzled in against his cheek, huffing and panting right where he could hear his exhausted teacher. He pushed his butt against her even more to help her along.

"Good." He laughed, bumping his butt against her clothed pussy, "Do it!" He snuggled in against her, wrapping his wings around the arms that wrapped around him, "Use me for your own pleasure, heh heh, I want it!" 

Alphys couldn't help it anymore. He gave her the clear! So she pounded his poor little butt more and more, using her big size and any strength she had to keep him in place, until she felt her body tingle and shiver, freezing up for a moment before pushing harder, her underwear wet with pleasure as it gushed out between her legs and through her clothes. Berdly gasped as he felt her wet fluids splash against his underwear. And his butt! She had her orgasm right up against him... one top of him... with him... he hadn't actually done this in person before, so making someone reach their sexual peak all because of him... it was a good feeling~

"Awww Alphys... heh heh heh, I'm happy for you~" Berdly teased, rubbing his butt against her lap. "You did it! To your own student..."

Alphys was exhausted, physically, and maybe a bit mentally! But not enough to feel a bit humiliated about that. A little bit of shame knowing maybe they shouldn't have, but, they wanted to! It was fine and consensual, and not only that, it was fun! And comfortable. Even a positive experience for her... though, she cared about helping him and being a good partner too.

"Now you cum." She bucked at his butt, reaching down under his tummy, and grabbing his underwear bulge. Berdly gasped! He was already horny and dripping down there, and now Alphys was touching his penis through it all, and wanted him to cum! 

"Should I... get it out of these?" she asked, wondering if she should get his penis out of his undies, if it wasn't obvious. She opened up the hole, and freed it for a moment. It hadn't really been seen by her even after all this time! To think, you could do all this sexual stuff with someone, and even get to your own orgasm, without actually seeing your partner's penis. The cool air hit his tip, and the lil length he had. Alphys eventually reached up and squeezed his bare naked penis. She could feel it herself. A smooth wet tip, and a wet feathery length (or whatever, use your imagination if you like something different...) she felt all his pre coating his parts, excited to feel his wet penis in one of these final moments! "Or should I let you stay in your underwear when you cum?" She fondled his penis as she fit it back into his undies, slipping it back in the hole, and fitting it over the front of his tip. She cupped and fondled his balls, and rubbed her tired hips against him more. "Well Berdly...?" 

"I-I think I'm gonna now, no matter what!" he whined, all the teasing and temptation being too much for him! And being wrapped up and humped by a girl was also fairly exciting... "J-just kiss me as I cum, i-if you can...?" The kiss of a gamer girl would set him free. She was happy to help! And as she humped away, she covered his feathery blue cheek in kisses, as the subby bird boy whined and moaned, thrusting his hips as he began to cum through his underwear! "Mmmmffff! Gahh, o-oh no...!" He felt every shot from his penis tip as it blasted the inside of his underwear, and dripped onto the floor just below. He humped and wiggled around, Alphys doing the same on top of him, while smothering him in love. She wanted him to feel as nice as he could as he came, and squeeeezed him close under her biggole body, until finally his funny lil bird penis tuckered out, and gave it's final few bits of cum.

"W-wow..." Berdly's eyes spun around in circles, feeling dazed. He got totally dominated by his big female teacher, and he loved it! He sank to the ground, even his wet penis and belly and face all needed to rest and laid limp against the classroom floor.

"Whew..." Alphys sighed, resting tired on top of him, worried her weight would be too much. "U-uh, just tell me if I'm too heavy..." she nestled her snout against his beak, resting together, tired, wet, and intimately close.

"Mmm, it's fine," the bluebird smiled. He actually kinda loved having someone big squish and cuddle on top of him. "I love it... this feels great."

Alphys tail waggled happily behind her big butt. She was glad! It felt nice to her too. It's not what she expected at all... but it was a lot better than she would have guessed.

The two of them stayed snuggled, wet and weird on the classroom floor, their undies soaked with sexual fluids after they'd riled each other up all afternoon...

---

8.

After a long afternoon turned evening, the two had maybe accidentally napped on the floor of the classroom for a little bit. For a bit Alphys was cuddled on top of Berdly, but eventually rolled off, which was probably for the best so he didn't crumble under her weight. The two woke up and stretched out their arms - Alphys still in her work outfit, minus the pants, and Berdly in nothing but his tighty-whities. Their crotches were fairly wet, but they didn't mind that. The big gal snuggled Berdly under her arm as they woke up together.

"Heh..." he huffed out, not sure what to say.

Alphys didn't know either... "Um, it was... nice..." she poked her finger on his blue, feathery chest. The bird gave a cute giggle, nestling into her big cozy side.

"Yeah, it was." He nodded, "I'll remember it! ...I uh, will keep my mouth as closed or open about it as you want... I'm guessing closed." 

Alphys grinned awkwardly, "Yeah, uh, I mean... I guess for now, it's probably best to be a little quiet about it. Words spread fast and students gossip! But uh, I'll make sure to add it to your extra credit."

Berdly laughed and started to sit up. "Well thanks! Uh, I mean, I like that! But obviously... all that was cooler than just a bit of extra credit. It was a good experience, right?"

She nodded, sitting up, "Yeah! I'm glad we did it." She leaned into him, rubbing down his bare, feathery back. "Maybe..." she thought...

"Hmmm? Maybe what~?" Berdly chuckled curiously.

"Maybe we'll do something like this again sometime?" She guessed? 

"I'd be more than okay with that!" The bluebird sounded excited! "Whether we did it again here in the class, or... somewhere else. I guess we'll have to think on it!"

Alphys nodded, the class was safe, sorta, but risky too... maybe her place would be better next time... but that had its own risks too! 

"Hey, uh..." Alphys grinned, rubbing the front of her panties, "I have a weird request..."

"What is it?" Berdly wondered, opening the front of his briefs and looking at the mess inside. 

"Can I... keep your underwear?" Her face turned red, but she had to ask!

"...You really want to keep it?" He laughed, how naughty! A girl wanting his sticky underwear... after all they did with it too. It was very personal! But... he did have pants he could still wear. "Sure Alphys." He almost thought about asking for hers, but he figured maybe that'd be too risky... him having his teacher's panties as proof of all they'd done... they were both aware of a lot of sticky situations that could come up from this! Even just taking naughty photos together would probably not be the best... they had to be discreet and careful.

"Alright, here ya go." Berdly stood up in front of her, hands on his waistband, a little nervous... she hadn't actually seen his penis this whole time! She saw his bulge, and felt it, made it wet, rubbed against it... and without looking she pulled his penis out, and touched it before... but she didn't actually get a good look! 

Berdly went ahead and tugged them down - the quick jiggle of his penis easy for Alphys to see, before his belly covered it while bending down. He shyly stepped out of his underpants, his balls and penis hidden fairly well between his legs and belly... and even as he stood back up, he held his underwear in front of his nude genitals, keeping them safe from her sight one last time. "Well... take 'em, they're yours!" 

Alphys reached out a shy hand to take them, and finally get a glimpse at his birdhood... but, then she blushed, tapping her snout, wondering if he'd understand.

"...You want 'em on there?" He laughed, but bent forward, and tossed his underwear on her face. "There ya go!"

Alphys turned red - the wet white briefs they'd fooled around in and with all day finally came off, and was on her snout! The scent of his seed, his penis, his feathery butt... everything was there on her nose, easy to detect! Not only that... but after going cross-eyed staring at his underpants, she looked up his naked thighs... and finally saw him, completely nude. Naked as a jaybird! 

She couldn't really say it was the first time for her if Berdly and other students didn't wear clothes all the time... but they didn't always have their genitals out either or anything! And even if so, it's not like it had the same sexual tone that this did. After a day of humpin' around and exploring in class, she got to see the fully nude fella she'd been with all day. It was a nice sight! Of course, it was after their... little climaxes and such, so, it's not as though he was all big and hard and proud down there. It was all actually rather soft, with his feathers kinda sticky and messy from everything. His balls tightened up nice and close, getting a chance to rest and recover. And his penis? Well it retracted alright! It was as cute as a button, a simple, tired, sticky, naughty little winky poking out soft on top of his balls after it'd gotten lots and lots of attention. It was cute! And she thought it suited him well. No wonder it was easy for him to go around without pants... and well, no wonder if he got made fun of and teased into wearing pants! It also made sense if maybe his personality had been more abrasive and rough, and annoying to others before - maybe having smaller parts stressed him out! Or, maybe it was usually bigger and right now it was all just shrunken up after a big sexy afternoon. Either way! She sure took in the sight! Now that she thought of it, when she saw weenies in mangas or anime, they were always soft, small, and simple. They couldn't show big, lewd, detailed dicks in those without it being porn! So, maybe hentai would have something bigger than this, but as she enjoyed the view, he was just like how anime drew penises. Maybe anime wasn't so far off and imaginary, and that's just how cute and small they often were! Did she... did she risk commenting on it?

"Heh, hey Berdly..." she lowered her eyelids, "it looks cute. Thanks for showing me."

"Cute?" He looked down, rolling onto his ankles, toes up and spread as he tried to see his penis - it was... soft! And bundled up tight there. He felt kinda embarrassed... "It's soft!"

Alphys blushed and nodded, "Yeah! I mean, it's cute, soft and little... nothing wrong with that, right?" She gave him an innocent smile, "I like that. It would have been a bigger distraction in school if it was too big... and it looks just like the cool mangas I read! I was never too sure how accurate that was or not... but I guess so!"

Berdly shuffled his hips, closing his legs together a little nervously under the spotlight. "O-oh... you uh, you like it?" Alphys nodded. "Cool! Ha... some folks kinda... made fun of me for it." The bluebird frowned, "I mean no one really cared most the way through school! But now that we're all older, we kinda... know what that stuff's all for, and how important it is, and stuff..."

Alphys nodded, "Aw, I'm sorry. I think it's just fine. And hey, see? We had a great time anyway! You made your own teacher finish, so you did well enough." She smiled, "I'm not always into guys, but if I am... I don't think I'd want someone big and intimidating... I'd want someone soft that'd go easy on me. Like Asgore!" Then again, maybe someone more strong and protective would suit her better... but she should probably stop listing off names of who she'd want to do this stuff with! "Uh, or you! You know... cute soft guys. Or girls. Whoever. It's not a bad thing to be how you are. Not to mention, you're a lot less... uh... you're getting along better with everyone these days! So that's good too!"

Berdly scratched his head, there were some awkward negative reminders in there, even though she was trying to be nice and positive. "Well... I may be odd, but I'm glad it didn't stop us. I wanna keep getting better over time too!" He felt a little odd, "Um, should I get dressed now?" 

Alphys laughed, it was nice of him to do all this, and talk with her naked! It showed his confidence wasn't all just pretend. "Well, sure, but first..." she wiggled one of her fingers as if to say, "Come closer." The bluebird nodded, and walked forward, his little weenie bouncing along the way. He stopped in front of her face, and she leaned in, closing her eyes, and gave it a kiss right on the wet tip!

"Heh heh...!" he grinned happily, "M-maybe next time, I'll get to see you naked more." 

Alphys sat up and nodded. "Oh yeah, sorry I was... mostly clothed. But yeah! Next time maybe, we'll both be all... n-naked." She did reach for his wing, and brought it up to her panties, letting him feel her clothed vulva nestled inside. He gave it a gentle grope and feel - finally getting to really feel what he'd only touched in other weird ways.

"Haha yeah! I'd like that." He squeezed it again and then leaned in to kiss her on her lips. "Thanks Alphys!"

She blushed and nodded, giving his naked butt a playful spank. "You're welcome. Heh, I can't believe I... humped your butt, and we both came..." she sighed, almost dizzy, letting him get dressed.

The bluebird nodded, getting into his shirt first. "One last look..." he spun around so she could see him in just his tight little t-shirt, before putting on his white jacket. He smiled at her all bottomless, "You know, maybe I'll just go like this! I do wanna be more confident about being bottomless again... like you said, it's no big deal!"

Alphys nodded, but then realized, "Uhhh.... well! Maybe tomorrow! Right now uh, your penis is kinda sticky... and your butt fur, er, feathers, look kinda wet..." she covered her face, "Folks might... wonder about what you were up to so long after school..." 

Berdly nodded, realizing she had a point. "Pants it is! Well, technically shorts." He smiled, before bending down and slipping them on over his legs. He looked up at her - his tight little penis and balls all soft and nice between his shorts and shirt, giving her one last view before he slipped them on up to his hips. Totally covered. "Thanks again Alphys." He went to go get his backpack. "Uh... I'll, see you later I guess huh?"

"Tomorrow!" She laughed, reminding him. "It's not the weekend yet."

Berdly nodded, heading to the door, but... pausing... and he quickly hurried over to her, and gave a needy little hug. It was too weird to do all that and leave without anything else! It was a big moment for him!

Alphys smiled sweetly, hugging and squeezing her student back. "Heh, aww... cuddle little guy. Thanks for the hug!" She kissed on his forehead and pat his back. There, that seemed better. "Here, let me unlock the door for you." And so, they headed to the door together, opening it up for him, and waving as he walked out of class for the day.

"Bye Alphys!" the bluebird smiled, waving goodbye before running off back home.

"Heh..." She nodded slowly, closing the door and turning back to her desk. She put his underpants on top, sat down, and just stared at them. They were... very sticky! And naughty! Full of memories of what the two did... her first naughty keepsake from another student. It was a surprise it all happened at all. But she was happy for it! She gently traced a finger around the crotch of it, imagining where his penis was, where his balls were - finding the wetting spot, where he probably came from... she even leaned in to sniff it a little. She was weird! She couldn't help it. Just curious...

9.

Eventually, she had to get ready to go home. She thankfully had a little bag she could put them in - no way could she keep his underwear in school! So with that, she grabbed her things, turned off the lights, and walked into the hallway - ready to head home!

"...Professor Alphys?" A sweet, motherly voice echoed through the hallway, and Alphys stopped.

"Huh?" She wasn't sure anyone would still be here. But it was the tall white goat teacher, Toriel! "Oh! Hey there ma'am."

She stared down at Alphys' crotch. "Umm... where are your pants, dear?"

...

Alphys looked down... but under her shirt and jacket... all she saw were her belly and bare legs! She couldn't actually see her own crotch and panties, but she could tell that's all Toriel saw!

"OH NO!" the nerd lizard yelped, she was really... caught at school in her underpants... by one of the teachers, no less! "Oh my gosh... I'm so sorry... I can't even explain!" She grabbed her crotch, and turned around, running to her classroom door, trying to get her keys and while covering her underwear-covered butt, sometimes looking back to notice... yep, Toriel was still there, staring in disapproval as the nerd squeaked on into class. She shuffled her pants on, buttoning everything up, before running back out to her door, all while beating herself up for being so stupid and forgetting she didn't have pants on. On one hand, it's great she got that comfortable about it. But on the other hand, no one else needed to see her undressed! She worried about how soaked her crotch looked. She couldn't see much detail there, right? She was staring for quite a while! Alphys was humiliated... even as she got out the door and ran through the hallway, she covered her face to save herself from Toriel's glares.

"S-sorry ma'am! Won't happen again! I just, I don't know! I forgot! Ahh!" The crazy little lizard ran out yelling, she didn't want to hear any of Toriel's thoughts, or how soon ago Berdly left or anything. She just wanted to get home, relax, and watch stuff to either get her mind off the day she had, or... maybe take a relaxing bath as she thought about it all over again. Maybe write some fan-fiction related to it? No, that was a no-no. She'd just take it easy tonight, and leave that part to someone else!
