Just. Undertale. Smut.

Alphine

On one morning in Hotland, Alphys was working on Mettaton's up-grade. "Alphy dear, are you done yet?" Mettaton asked with slight impatience in his voice. Laying there on the lab table for 30 minutes was forever when you have so many monsters to entertain after all. "J-just hold on a s-second" said Alphys nervously. "I h-have to put in the finishing touches" She wasn't sure if she had done it right or not but dammit, she still had to do it. "A-and there." She said as she put in the last sack of lubricant. Mettaton got up with a start. He ran into his room to check to see if it worked. He caressed it a little to get himself riled-up. "Oh my." Mettaton said with pleasure in his voice. He searched around with his fingers. He found his new clit and began rubbing, he rubbed faster as the pleasure intensified. After a while, Mettaton decided it wasn't enough. He stopped rubbing. He snuck out of his room and into Alphys's. He dug through the drawers of her dresser and... bingo. Mettaton fished out a huge, black, foot-long dildo made with the finest warts. He licked his lips and shoved it right up his juicy entrance.
                                  *
Meanwhile with Alphys, she was working on her computer. She heard little breathy moans in the background. It seemed to have came from her room upstairs but she chose to ignore it. Suddenly, the phone rang. *RING RING RING* Alphys picked it up. "H-hello?"
"HEY BABE!" Exclaimed a very sexy fish. It was Undyne, Alphys's girlfriend. She was nervous but with Papyrus cheering her on, she could never lose.
"Oh hello, U-Undyne." Said Alphys.
"So i was thinking t-that we sh-sh-should maybe catch a m-movie?" Undyne sputtered out. Alphys was surprised that she got asked out. Her face was red as a tomato. She opened her mouth to say something but suddenly a loud moan came from the background. "OH YES, DADDY!" Said the moaning voice. There was now silence among the two on the phone. Undyne was super excited. She actually said yes! Even though she was her girlfriend, it was still a thrill that she said yes. Alphys was sputtering. The noise embarrassed her so badly that she almost hung-up. Undyne quickly stated "okloveyouseeyoulaterbye." Undyne hung-up the phone in such a hurry that Alphys didn't have time to say "I love you too".

Mettaton came out of the room with a start. Alphys was in the kitchen making something. Mettaton walked up to her.
"Hi there Alphy darling." Mettaton said awkwardly.
"Hello..." Alphys said flatly
"What you up to?"
"M-Making fudge."
"What for?"
"So me and U-Undyne can eat." She turned around. "Mettaton, what was that no-" the doorbell rang. "Hold on" said Alphys with a finger up. It was Undyne dressed up in a dress with the words "Papyrus is cool" on the bottom.
"You ready?!" Undyne exclaimed picking her up to kiss her. "O-oh hey Undyne. I-i've made some fudge i-if you want some.Ok so i got the pokemon into the boxes and i pressed save data so it saves it to my sd card now it wont show up in my game what do i do"
"HELL YEAH, I LOVE FUDGE!" Yelled Undyne.
So Undyne entered Alphy's lab and she waited in the living room while Alphys went to the kitchen to get the fudge. So Alphys got the fudge and they both enjoyed eating it. Alphys looked at Undyne's hot knockers. For a moment she was dazed, fantasizing about tearing off her clothes and pouring that fudge all over her naked tits then licking it off. Undyne noticed this and she felt the same. She wanted to slurp up her warm juices like spaghetti. But she casted this aside for now and said "Hey Alphys, we're gonna be late, we better hurry this up." Alphys snapped out if her daze and said "O-oh ok."
                                 *
What Alphys didn't know however, was that Undyne and Papyrus had been planning this date since last week. They went to the dump in Wetland. There, there was a table prepared with a plaid red tablecloth. "O-oh m-my you shouldn't have!" Exclaimed Alphys.
Undyne smiled. "Oh, but I wanted to, babe." So they sat down on opposite sides if each other and held hands on the table fir a minute until a rather dashing waiter-. Wait. Sans?! Undyne was enraged to see the skeleton in a french mustache and a waiter suit. "Sans?! What the hell are you doing here? Where's Papyrus?!" Said Undyne.
"oh, well my bro's on a date with Mettaton. i had a slight feeling Papyrus was doing something else, so i came here 'fast as i could" explained Sans. Alphys held Undyne's other hand and told her softly to calm down. "Alright." Sighed Undyne. "But I want my face-steak here quick."
"I-i'll have the face-steak too p-please." Sans nodded. "anything else gals?" They both shook their heads and Sans teleported away. Before the couple could say anything to each other, Sans teleported back with two plates of face-steak. Alphys looked up. "W-where did you get t-the face-steak?" She asked "eh, that's not important." Said Sans. "what is important is that you two enjoy your little date. welp, see ya." Sans winked as he teleported home to take a nap. As Alphys and Undyne enjoyed their steaks, they both looked at each other's scaly tits, and fantasized about how they wanted to see them jiggle as they laid each other down and fucked them right up their scaly wet pussies. After thirty minutes of total silence and staring at each other's breasts, they finally finished their steaks. Undyne finally spoke up. "So," she said in a seductive voice. "Your place or mine?" She winked. Alphys's nose started bleeding. Was she really about to get some fishy love? Alphys couldn't wait. "M-mine." Alphys responded. So they got up and went to Hotland, where they finally got to Alphys's house. "That was fucking awesome, Alphy!" Exclaimed Undyne.
"Y-you really think so?" Alphys asked.
"Hell yeah, that date was the best!"
"W-wanna w-watch some videos?"
"Yeah"
Alphys noticed a VHS tape on the floor.
"H-hey look, a V-VHS tape th-that says "D-Date night,""
Undyne saw the glitter on it and remembered that Sans said something about Papyrus and Mettaton going out on a date. She was intrigued to know what they had done to be worth recording. "Looks like Mettaton's. Let's watch!" Exclaimed Undyne.
"H-How do you kn-know?"
"The glitter."
                               *
So Alphys and Undyne both watch the tape and... oh my. That. That was unexpected. It was Papyrus and Mettaton giving oral sex to each other.
"W-what. The. F-fuck?" Alphys and Undyne questioned everything they knew about the two. "I'll never look at paps the same way again." They both had no idea how to react. So they decided to never look at the skeleton or the robot the same way ever again. But something about that tape inspired them. Inspired them to do something they never did before. Undyne finally cracked under the sexual tension between the two. She puffed out her chest so hard that her coat and button-up shirt pretty much disintegrated. Showing her bra. She puffed out her chest a second time and that pretty much disintegrated too. "Do whatever the fuck you want to me, babe" She said in a seductive voice. So Alphys ran to the kitchen, grabbed the unfinished fudge, microwaved it so it could melt, and ran back to Undyne who was sprawled out on the couch waiting for her. Alphys poured the melted fudge all over those c-cupped, scaly, pepperoni nipped bresticles. It felt hot to the touch on  Undyne's sensitive tits but she didn't care. She wanted Alphys's magic tongue to make the fudge disappear. Alphys licked up that fudge off of Undyne's girls like a dog would lick off food on your face. She made sure to get under those scales and around the nipples. When all the fudge was off, she got up and looked at her work. Her lover's bust was now shiny with Alphys's saliva. "More." Undyne moaned. "More." Alphys grabbed her boobs like a savage and lapped up on her nipples. The pleasure coursed through Undyne's veins. She knew Alphys was determined, but she never knew she could please a woman so well. Alphys kept licking and sucking, pleased as Undyne's moans got louder and louder. Undyne's hands were in her pants. She was fiddling with herself. Alphys saw this and developed a courage she never felt before. "I'll get that for you." She said in a low seductive voice. She slowly took off the fish's pants and what was revealed was amazing. It was the folds of Undyne's hot, wet womanhood. She told undyne to wait a second and went to her room. She dug through a drawer and found a strap-on penis. She strapped it on to her waist and ran back to Undyne. She showed it loud and proud to her lover. Undyne was impressed. It was huge, girthy, long, and best of all, black. Alphys stuck the pole of pleasure into her lover's hot, wet, sticky, dripping folds. Undyne moaned the moans of sensuality and pleasure. Both striking her like lightning. With each pump, Alphys was satisfied to know that Undyne had a little case of Alphy love. Her face she made as Alphys was humping made her entrance wet. She wanted to feel Undyne's sweet clit on top of hers. For 45 minutes, the humping continued. Then finally, Undyne squirted out all her cum on Alphys's face. Alphys grabbed globs of it and licked it off her fingers. She licked around her lips to get every last drop of it. Undyne felt obligated to give Alphys the same pleasure. She pushed Alphys down and took off her strap-on cock. "My turn." Undyne seductively said. She was about to put it on when Alphys said "No. I want to feel that huge clit on too of mine. Sc-scissor me Undyne. Cut me up like a piece of paper."  So Undyne smiled lustfully and threw away the penis. They both got into position and started. The two hot, wet, hungry clits clashed as they both moaned out in pleasure. It felt amazing. Pain and pleasure intermingling, coursing through their veins like lightning. Their scales both meeting with one another. Coming off and chipping away as they pumped harder and harder. Making sure to get under every fold. For at least an hour this continued. Until. Yes. They finally did it. They both squirted. Cum was all over the couch they both licked it up and Alphys noticed a scaly ass that needed eating. She grabbed Undyne's  bubbly ass and started licking on her asshole. A slight metallic "oh my" could be heard but they didn't care. Alphys spat on that ass and continued to rim around the edges. It felt fantastic. Undyne had never fucked anybody fir that long before. Now, her ass was being eaten out by a dinosaur and she loved it. They took turns eating each other's asses out until they came again. Then Undyne had an idea. "Hey babe."
Undyne said.
"What?"
"Y'know what my favorite number is?"
"What?"
"69." they both smiled and got to work. The pleasure was at it's peak now that they had both came more than once. They made sure to eat every and I mean every fold. They both put one hand on their clits and started rubbing. They humped at each other's magic mouths until they came for the third and fourth time. The couch was wet with ovarian fluid at this point. When they were done, they both cuddled naked in the couch until morning.
                              *
When they woke-up, Undyne had to borrow a shirt from Alphys because hers was virtually disintegrated. Undyne left Alphys's house with a good-bye kiss. At breakfast, Alphys whipped-up some ramen noodles as Mettaton giggled. "W-what's wrong Mettaton? Alphys asked
Mettaton waved down his hand. "Oh nothing darling, just that my Pornhub video got a million likes." He showed Alphys his phone and what she saw was devastating. The video was called "Lizard Fucking Fish." The duration was for two hours.
