One morning Riley and Topanga were having breakfast together as Topanga said, "You know I'm really going to miss having breakfast with you in the morning regularly once you're away at college soon." Riley nodded and said, "Yeah. But we'll make it through." Topanga then said, "It's just sad for me to think about you moving away in a few weeks and being so lonely." Riley then said, "Well... I don't have to be lonely. There's this gifted magnet school right near my college, and I sent in an application on Auggie's behalf, and it looks like he's gonna get in. So if it's okay with you, maybe we could have Auggie live with me in college and I could be his guardian so he could go to this special school." Topanga looked down for a moment, and then said, "Riley, you really want him to live with you so you can both keep having sex. Isn't that right?" Riley looking caught off guard said, "What? No. It's just... I..." Topanga sighed and said, "Riley, I know you two have been going at it for quite awhile now, and... trust me when I say having a sexual relationship with someone of a different age like this just doesn't end well. Trust me, I know."
A puzzled Riley then said, "What? But I thought dad was the only guy you..." Topanga then sighed again and said, "Your father was the first man I made love to. And in my mind, I justified... making love to a woman doesn't count." A wide eyed and surprised Riley said, "Wait. Mom. You're bi!?" Then Topanga said, "Well not anymore. I mean maybe I guess I still am, but... regardless, my parents growing up being so busy with their work had this teenage nanny living with us for a few years named Nebula. She was like an older sister to me, and we even started telling people we actually were sisters. And just like you and Auggie, we started fooling around with each other when our clothes were off, and... well we had lesbian sex many times. Like: many, many times. Nebula promised me our secret relationship would continue when she started college, but... eventually we drifted apart. As Nebula became an adult, she found that she needed a proper adult partner who could better relate to her, and... it broke my heart when she said it was over. And I don't want you to experience that too. Riley, you need to end this thing you have with Auggie while you can still make it feel mutual. You don't want him to experience a broken heart. And plus, when siblings that are in a sexual relationship break up, it's all the more painful because due to their taboo relationship, they feel like they can't talk to anyone about it. Thus, they feel even more alone and broken. Please Riley. You have to calmly and peacefully break up with Auggie as soon as possible." Riley sat silent for a moment as she said, "I... I'll think about it."
In the middle of the night, Riley laid naked on her bed staring at the ceiling and thinking. Then Auggie opened the door to the room and sneaked in naked as he said, "Hey Riley." Auggie then jumped into Riley's bed and gave her a quick peck on the cheek. Then Auggie with an excited face said, "So did mom say yes? Am I gonna move in with you when you start college?" Riley sighed and said, "Mom explained to me how... that would not be a good idea. She told me some stuff about how when a girl grows up and starts college she will become more drawn to people her own age, and... I'm starting to think she's right." A concerned Auggie then said, "Riley... what are you saying?" Riley then with tears in her eyes said, "Auggie... I... I think I need to break up with you. Not because I want to. But because I'm worried about you getting hurt somehow if I start seeing someone else in the near future." Auggie was silent for a moment, but then said, "Riley... we both knew there was a chance this wouldn't last forever. And if it ends... don't worry. I'll be fine."
Then Riley said, "But Auggie, I don't want to see you in pain. And because brothers and sisters having sex with each other is so taboo, you'll never be able to talk to anybody about how you feel. Not a friend, not a counselor. Nobody." Auggie then said, "But we're not alone Riley. Tons of people out there have had sexual relationships with their siblings growing up. I've already looked into it. There are discussion boards where people chat about it online. And even a few of my friends from school have opened up to me about how they lost their virginity to their family members. Even Ava told me she lost hers to her cousin on vacation. And I've already told her about us, and she's okay with it. Trust me Riley. I'll be okay." Tears appeared in Riley's eyes as she said, "Auggie... I'm so happy you were my first. When a girl is young, I don't think there's anybody more perfect to take her virginity and show her what sex is like, than a loving and protectful brother." Auggie smiled and said, "Riley, no matter what happens... you'll always be the most important woman of my life."
Riley and Auggie then looked deeply into each other's for a moment. And then suddenly the two kissed and wrapped their hands around each other's bodies like never before. Auggie began to rub his hands all over Riley's body quickly. Riley meanwhile moved her hands quickly up and down Auggie's back, butt, and legs. They broke the kiss as Auggie reached over to a nearby drawer but Riley stopped him. Riley then said, "No Auggie. No condom tonight. I want nothing to separate us. I want flesh completely touching flesh." Auggie smiled as he re-positioned Riley to be under him and separated her legs a bit. Auggie looked down at Riley as Riley gave Auggie one more nod showing that he indeed had her permission. Auggie then pushed his penis down into Riley's vagina. Riley's eyes widened greatly as her mouth opened up wide and she moaned incredibly loud. Auggie pulled out a bit but then pushed in even further. Riley moaned loudly as she felt her brother's skin rub against her own. Riley moaned as she said, "Oh Auggie, you feel so amazing!" Auggie smiled and said, "How about you take lead now?"
Auggie then switched positions with Riley so he was on bottom and she was on top. Riley began to ride Auggie at a slow pace at first, but then began to quicken it. Auggie began to squeeze Riley's butt which made her moan even more. Riley began to bounce up and down very quickly as hard as her brother's penis was throbbing inside her body. As Auggie squeezed Riley's butt hard, Riley pushed her hands onto her brother's chest. As Riley felt Auggie's penis push deeper into her she said, "Errr. Ohhhh. Ahhh! Oh God! Ooooohhhh! Harder Auggie! Harder! Oooooh! YEAH! Oh God! OOOOOHHHHHH!" The two's bodies shook together very quickly like never before. They were both shaking faster than ever before but completely in sync. The two's bodies moved like they were one mind and soul. In this moment the two felt completely united as Riley sad "Mmmm. Yes! Oh yes! Ohhhh! I love you Auggie! Ooooohhh! I love you!" Then as Auggie kept shaking he said, "Oh God Riley! Ooooohh! Oh, I love you! I love you! Ooooohhhhhh!" Then as the two each felt their climax approaching Riley with sweat all over her face said, "Oh God, I will always love you forever Auggie Matthews! Oooohhh! Aaaaaahhhhhh!" Then Auggie said, "Oooooohhhhh!" And in that moment, the two both orgasmed together and Auggie let it all out. Auggie shot load after load of semen deep into sister's body while Riley smiled as she felt the warm love of her brother come into her. The two both shook for several moments as they felt the pinnacle of their love be felt. Then eventually exhausted, the two just laid down together exhausted.
As Auggie and Riley laid nude together, Riley smiled and said: "That was the most amazing feeling in the history of everything." Auggie smiled too and said: "I'm glad you liked it Riley. And remember... no matter what happens, I'll be okay; because I'll always have the happy memories of this." Riley nodded and said: "And I meant what I said. I will always love you forever Auggie. You make me feel like the most special woman in the world and that's all I've ever wanted. Thank you for being my first." Riley then hugged Auggie tightly as he continued to hold Riley close to him; leading to the two falling asleep in each other's arms.
