The days in Gravity Falls had been uneventful since Bill was defeated. Dipper and Mabel had left for home in California the week prior and Soos now owned the mystery Shack, yet needed guidance from Stan before he could run it on his own. Ford and Stan had wanted to travel the world like they planned to when they were younger, but decided to wait a bit until Soos got the hang of running the Shack. Ford spent most days in the basement studying. Everything just had a sense of normality for once since their exciting, adventure packed Summer ended.
Later that night Soos had gone home to his Abuelita, Stan closed up the Shack, and Ford came out of the basement to sleep. Ford lumbered up the old, creaky wooden stairs to take a shower before bed. Without realizing it Ford walked into the bathroom to find his twin brother Stan in the shower already. An intense blush formed on Ford's face. It seemed to him that Stan had yet to realize the door was open and had someone watching him. Ford attempted to close the door silently, but failed due to the Shack being so old. The door made a loud creak which alerted Stan. He turned around to find his brother staring at him from the entrance to the bathroom with a deep blush set in on his face. Ford couldn't stop staring. He hadn't seen his brother naked since they were children when it's socially acceptable with them being small children and all.
"You like something you see Sixer?" Stan said, raising his eyebrows and looking at his brother with a devilish grin stepping out of the shower and grabbing a towel.
Ford had never told anybody he was gay. Mainly due to the social norms of when they were children. He knew that since he'd come out of the portal they'd changed a lot and society as a whole was better with acceptance, yet he still felt the need to hide it. Making it seem taboo to himself.
"Well?" Stan asked further.
"Um… I. I.." Ford stuttered. He quickly slammed the door shut and ran to his room down the hall, shutting his bedroom door and locking it. He threw himself onto his bed. He never thought he'd be sexually attracted to his own brother! He knew he was into men his age, which was around 60, but he never thought about his brother like that. Remembering how Stan looked when he stepped out of the shower made him hard. Ford began thinking of his brother sexually. He began thinking of things he wanted to do to his brother. What he wanted Stan to do to him. Just the thought of them kissing made his erection even harder. He slowly unzipped his pants and pulled his 6" cock out and began to rub himself. He moaned loudly. Loud enough that Stan heard him. He wanted Stan to bend him over his bed and fuck his brains out. He wanted to ride Stan's cock as he vigorously kissed his hairy body and unshaven face. Ford rubbed himself harder until he climaxed screaming Stan's name in utter bliss shooting his load all over himself and the covers of his bed. As Ford finished and looked up, he realized that Stan was standing in the doorway staring at him. He'd picked the lock and found his brother masturbating to him.
"It!.. It's not what it looks like Stanley!" Ford said, embarrassed and full of shame. Stan stared at him for a while longer. Ford couldn't tell if he was angry, happy, sad, disappointed. He couldn't rushed over to Ford and picked him up off the bed. Stan held him there for a bit in a loving embrace. Stan broke the hug and stared deeply into Ford's eyes.
"Do you want to know the real reason, besides the fact that you're my brother, that I brought you back from the portal?" Stan asked.
"Yes Stan I'd love to know." Ford said quietly.
"It's because I love you. That night I got your letter to come to Gravity Falls I thought it because you were going to tell me you loved me. That you'd want to spend the rest of your life with me. As lovers. Stanford I've loved you more than you know and when you invited me over to just tell me about your stupid portal I was furious. I worked my ass off to get you back and I'd do it all over again just to enjoy this moment right here." Stan said with tears in his eyes.
"Oh Stanley that was beautiful! I love you." Ford said. Stan leaned in and kissed Ford passionately. Their tongues intertwining as they shared their love with each other.
