Chapter Text
Everyone in Springfield is enjoying the special holiday that is Valentine's Day. Every individual is either having romantic dinner, going to motels or hotels for one night only. Or if they are alcoholic lovers, they would spend the whole day at Moe's. Now, they are a few individuals who either…say…do not participate and value in this lovey dovey holiday or unfortunately do not have a valentine to love and be with to the end. Especially when that individual has no luck or has no game in getting the opposite sex to date nor have good sex. That is when he comes into play. Well, his paid employees.
Sitting down in a booth at Krusty Burger while being invisible from the eyes of mortals, a black buffed average height cupid was going over his tablet that had the list of people that are in need of a love arrow in the ass. He only had two individuals that he purposelessly constructed to happen. The reason behind it is that cupids are trained in the arts of knowing which individual is right for one another before hitting them with their arrow that has their name written on it. Let alone they record and collect their favorite client lovers dating or making sweet love.
"Alrighty then I only have two of my soon to be favorite clients." said the cupid named Tom.
All of his friends that are just like him brag about their favorite certain category collection videos that they showed them when having a get together. And that certain category of Valentine recorded tapes collection is none other than…incest. Yes, you read it, incest. Cupids are known to have lustful watching tastes for romance between cousin and family. But for Tom he is only into cousin and sibling incest. He ain't so sick like his other cupid college buddies and his boss, who is into all types of sexual romance.
His boss. The Cupid aka King Valentine. Tom looked at his bag that had only two arrows inside. He put his tablet up before going back to eating his lunch.
"Alright my two soon to be love birds, once I am done eating my lunch I will come and give you two your dose." said Tom, before taking a bite of his triple burger.
After eating and grabbing his stuff, Tom exited the restaurant before extending his thick wings and flew to the skies. He flies through the clouds with smooth sailing. Yep, Tom remembered when getting the job and being permanently assigned to Springfield upon getting it in the drawing. His soon to be incest lovers are siblings. The names were Bart and Lisa Simpson. They may have their typical difference as brother and sister, but Tom knows there is love for the other. And deep down they have a small incestal fire in their hearts, and Tom is going to put the large wood and fire fluid in their fire.
"And there is my destination." Tom flew down and landed on the front yard of the Simpsons house.
Tom easily went inside the Simpsons home by simply phasing through. Just like Santa Claus, all cupids check their list and check it twice to find out who is single or not. Tom knows exactly where those two teens are. He found them in the living room on the couch playing an Itchy and Scratchy videogame on Xbox One X.
"Alright you two. Happy Valentine's Day and have forever romance." said Tom, turning the tv off to get their attention.
"Hey, what the fuck happen to the tv?." Bart frowned when getting up to check the tv.
"It might be time for a new tv. I don't think our parents don't have any money to spare at the moment." said Lisa, going over to check if the tv could have been unplugged.
Tom smiled when pulling out an arrow that had Lisa's full name on it and put it in his bow and shot it into Bart's behind. Then he took out the last arrow that had Bart's name and shot it at Lisa's behind.
"Now, let the incest valentine begin." said Tom, before transporting back to his home to go watch and record Bart and Lisa.
Back with teenage Bart and Lisa. After being hit by the magical arrows the two have felt heated incestual lust for one another. Without any hesitation, Bart and Lisa came together and kissed on the lips. Bart rubbed his hands all over his sister, rubbing her nice fat yummy ass. Lisa had her hands all over her brothers hair.
"Mmmm, Bart, why haven't we fallen for each other a lot sooner?. I feel so damn happy." Lisa spoke while giving out a moan.
Bart stopped kissing his sister's neck and looked at her. "I do not know, Lis. We wasted good years. But we will make up for it on Valentine's day."
Lisa put on her sex grin. "You damn right we can, Bro."
Bart picks up Lisa's bridal style and then twirls her around a bit while making her giggle. Carrying her upstairs to his bedroom while keeping his balance. Once closing the door and putting his sister on his bed, Lisa started to remove all of her clothes and got all the way naked. Bart did the same and showed his hard thick eighthinch penis which made Lisa's eyes lit up with lust.
"Wow, Bart, I did not have any idea you had a monstrous cock." said Lisa.
Bart chuckled. "Like Dad told me when he gave me the birds and the bees talk. The male Simpsons have monstrous dicks."
"No wonder Mom stayed with Dad for so long. And Mom told me that in her family for women they will have the tits the size of hot ass pornstar. Now, come here and lick me up!." said Lisa.
Bart grinned. "Don't mind if I do, Sis."
Bart came over to Lisa, who laid back and opened her legs up, went on his knees and put his head in and started licking his sister's sweet pussy that tasted like sweet honey. Lisa moaned while curling up her toes and grabbing onto the covers when feeling Bart's wet tongue rubbing all over her womanhood. It felt awesome. Bart licked and sucked Lisa's dripping cunt in utter enjoyment. He can never imagine how tasty a girl's downstairs would be, much less being his sister's.
"Ahh, Bart!. Ahh, Bart!." Lisa called her brother's name out with great pleasure. "Bart!. Get inside me. Please!. I want to feel you in me, big brother."
Bart stopped eating his sister out and looked at his sister. "You sure, Lis?. You do know that it is going to hurt for the first time, right?."
"I know Bart. I'm willing to lose my virginity. I wanted to give it to you. My big brother. The one that will never let anyone hurt me. The man of my future kids. My future husband." said Lisa, feeling her heart beating strongly.
Bart nodded. "Alright, Lis. Get ready."
Lisa prepared herself for the inner pain that is going to happen to her. She knows that the pain is only temporary and she will soon feel that amazing pleasure. Bart stood up and placed Lisa's left leg on his shoulder. Then he grabbed his dick and gently slid it inside Lisa's warm wet pussy.
"Tell me to stop when you can not take the pain much longer." said Bart, as he started thrusting within her.
Lisa bites down onto her teeth. Fighting back the pain as she wanted to give her big brother her virginity. Bart pounded his sister as he was loving her walls all over his cock. Lisa can feel the blood running through her vagina as the pain is getting into her. Bart asked Lisa if she wanted him to pull out, but she told him to keep it inside and keep pounding her. With a few minutes of pounding, Lisa started feeling her walls have finally been broken and now she is laughing in utter pleasure.
"Oh, Bart, you are so good inside of me!." said Lisa, moaning out hard.
"Well, get ready to feel good in your mouth, Sis." said Bart, pulling his cock out of Lisa.
Lisa got up and lay on her stomach as Bart put his hand on the back of her head, before guiding his dick into her warm wet mouth. Lisa deepthroat Bart's cock in such happiness. She hasn't had meat in her mouth ever since she became a vegetarian. However, Tom had fixed that with his arrow and more so. Bart had his tongue out with a facial expression of pleasure when Lisa took over. She sucked his right nut before putting her whole nutsack in her mouth like a jawbreaker.
"Damn, Lis, your mouth feels so wet and hot. I just do not want you to stop." said Bart, having a little bit of saliva running down his chin.
Lisa licked and sucked until Bart precum into her mouth. She pulled out and then swallowed her brother's precum before grinning up at Bart.
"Ready for my ass?." Lisa stands on her hands.
Bart grinned. "Hehehe. Well, your buns are looking good to bang."
Bart got on his bed on his knees and then slapped Lisa, nice sweet fat ass. Lisa laughed and shook her fat hips. Bart grabbed his sister by her waist and stuck his cock in her tight anus.
"Ahhhh, shit that feels so fucking good!." yelled a lustful Lisa with her tongue out like a dog.
"Damn, Lisa, you are so tight!." said Bart, pounding her like a nonstop pumping machine.
Bart kissed his sister's left ass cheek before slapping her right ass cheek. Feeling more precum coming out and loving the sweet feel of Lisa's anus walls grabbing his dick. Suddenly the two stopped fucking when the door opened and in came their parents. The two frozen in great fear of being caught in the act that they have committed. They were expecting fussing and yelling along with major punishment. But they got what they did not expect. Love and support.
"Oh, sweeties, we did not mean to interrupt your sexing." said Marge, smiling at her two kids.
"Wait." Bart looked at Lisa who looked at him. Then looked back at their mom and dad with a confused look. "You guys are not mad at us fucking eachother?."
"Don't you guys are disgusted and disapprove of incest?." asked Lisa, in surprise.
"Oh, Lisa." Homer waves it off. "We are in different times. We accept all kinds of love. Including incest. Besides, me and your mother had figured that you two were going to hookup."
"That, and it is proven that incest of either cousins or siblings have a much stronger relationship bond than regular relationships. Especially marriage." said Marge, happily.
"Thanks for being understanding and supportive guys." said Lisa, feeling happily accepted for her sexual lifestyle.
"You guys are awesome." said Bart, who too is happy.
"Now, then we will just leave and let you two enjoy your valentines." said Marge, leaving.
"Bart, don't get your sister pregnant. Marriage first and I am not ready to be a grandpa yet." said Homer, leaving with the closed.
Lisa looked at Bart. "Ready to resume?."
"Fuck yes." said Bart, resuming to pound his sister once again.
Bart eventually came and filled Lisa's anus up. The two lay together in bed with the covers on them since it was getting cold.
"Mmmm, I think we made up for that lost time, Bart." said Lisa, snuggling into her brother.
Bart holds Lisa in his arms. "We sure did. Want me to fix you a salad after we are done sleeping?."
Lisa shook her head. "No. I want steak."
"Steak?. Lis…you want meat?." Bart asked in disbelief.
"Well, I somehow lost the taste to be vegan. I'm going back to eating meat. And seafood. Happy Valentine's day, handsome." said Lisa, closing her eyes and going to sleep with a smile.
"Same to you as well, babe." Bart closed his eyes and went to sleep with his sister/girlfriend.
Tom, who is in his home sitting his chair and finished recording and watched his favorite couple fucked, was done jerking off and grabbed his nearby box of Kleenex to clean himself off.
"I love my job. Bart?. Lisa?." Tom smiled at the sleeping couple in pure happiness. "Happy Valentine's day my little incest siblings.
