For the uninformed,a cherry lemon is a lemon with little to no back story. It goes straight to the lemon.

Alphys was shocked. Undyne threw her on the couch and roughly kissed her. Alphys then slowly melted into the kiss. Undyne's tounge asked for entrance and Alphys denied. Undyne smirked and touched Alphys's crotch. Alphys yelled and Undyne inserted her tounge into Alphys's mouth. Alphys blushed hard and attempted to fight for dominance,since Undyne was way stronger,Undyne won and kept exploring.

Alphys kept blushing and trembling a little,so Undyne decided to let Alphys explore her wet caverns(Why do I keep saying that when something like this is happening? Wet caverns...I guess that's the only thing I can use for now I guess...) and Alphys forced herself to. Undyne let out a moan and both girls gasped for air. "Alphys...you're a good kisser..." Undyne said and Alphys kept blushing."S-so are you...U-Undyne..."Alphys replied.

Undyne smirked and began unbuttoning Alphys's lab coat. "Ah! U-Undyne! Th-thats my lab co-Ah!" Alphys was interrupted by Undyne massaging one of her breasts and licking the other. Alphys loudly moaned and tightened her grip on the couch. She was starting to turn red in blush. Good thing Mettaton was at one of his hour-long shows that started when Undyne came over.

Undyne started sucking on the breast she was licking and tightened her grip on the other one. Alphys moaned louder and started panting a little bit. Undyne stopped and undressed herself in front of Alphys. Alphys helped unclip Undyne's black bra and Undyne took care of the rest. Undyne was blushing a little and walked towards Alphys. She pinned her back on the couch and flipped both of them over.

"So...I guess its my turn..." Alphys said. Undyne nodded and smiled. Alphys was nervous at first then she kissed Undyne with both of their bodies touching each other. Undyne kissed back and inserted her tounge into Alphys's mouth. They both were fighting for dominance and this time,Undyne went easy on Alphys. While doing so,Undyne flipped them back over and reached for Alphys's crotch and put in her middle finger. She began thrusting her finger and Alphys gasped for air and screamed in pleasure.

"Harder Undyne!" Alphys begged and Undyne happily obeyed. She inserted another digit and thrusted faster. Alphys moaned loudly an Undyne decided to put in another finger and thrust as fast as she could. "Ahh! Undyne! I'm going to cum!" Alphys shouted,then got her juices on Undyne's fingers. Undyne licked her fingers clean and flipped them over again. She spread her legs open and begged Alphys to pleasure her.

Alphys smiled and inserted her tounge into Undyne's core. Undyne gasped and moaned. Alphys pushed her tounge in and out of Undyne and grabbed onto Undyne's thigh. Undyne begged for it to be rough and Alphys did so,she inserted two fingers and began thrusting. Undyne moaned loudly in pleasure and tightened her grip on the couch. "Alphys! I'm going to..." Undyne then cummed on Alphys's fingers and Alphys cleaned her fingers up.

Undyne then stood up and walked to her jeans. Alphys thought she was going to get dressed,but she got something from her pocket. A long thick glow stick with a white handle. "So worth picking this up at the dump,don't worry,I washed it before I got here." Undyne walked back to Alphys and warned Alphys,"This may hurt a bit at first,but you will get use to it once enough time passes." Alphys nodded and spread her legs open.

Alphys couldn't believe what was about to happen. She was about to get screwed by Undyne,in a hot way too. Undyne inserted the glow stick into Alphys and Alphys screamed and started crying hot tears. Undyne kissed her tears away and started whispering sweet things to her ear.(Does Alphys even have ears? I dunno. Oh well,continue the lemon!) Alphys moaned in pleasure after a few moments and Undyne began to thrust the toy inside of Alphys.

"Ah! Undyne...Faster...harder..." Alphys pleaded. "Beg." Undyne commanded. "DEAR GOD UNDYNE! FUCK ME! FUCK ME HARD!" Alphys screamed. Undyne smirked and thrusted it as fast and hard as she could. "Undyne! I'm going to cum!" Alphys shouted and she got her juices all over the toy. Undyne smiled and got them both dressed and were both on the couch.

"Alphys...that was so hot..."
"I know..."
"We should do this more often..."
"Mhm..."
"Love you Alphys."
"Love you too Undyne..."
