Little more than a week had gone by. So far, things were going fine. Being with your mother had been awkward the first day, but after that it was just as if you were living at home again. Albeit in your father's body. Luckily, when it came to attraction towards your mother, you felt nothing of the sort. Just as always, she was simply your mother. You could tell it was weirder for your mother thought. No wonder, you were in her husband's body. But that seemed to have gotten better the last few days as well. So far, the most awkward moment had been when your mother had hugged you from behind and almost given you a kiss on the cheek - old habits die hard. But after a while you had both laughed at it. It was just force of habit, after all.
Today was no different. You were at home, doing nothing, as you didn't have to do anything. That was when your cellphone started ringing. It was your dad. "Hi dad!" You answered. "Hi John!" He answered back. "This is going to sound... weird. But I'll feel better if I ask for permission first." He said. "Permission?" You asked. What could he need permission for? "Yeah... Long story short. I installed Tinder. I understand that's all the rage for casual dating nowadays." He said. You felt your stomach clench. Was your father using his son's body to try and date people? "What? Tinder? Why would you..." You said, before your father interrupted you. "Well, I mean, me and your mother have an understanding. I'm allowed to... spread my seed this year. But she'll be allowed to play the field as well. We've been married a long time and with the situation at hand, we figured this would be a good chance to, you know, experiment." He said. As this was perfectly normal. "But, I felt like I wanted to tell you. I'm in your body after all. I figured it might feel weird knowing I'd... well, you know, as you." He said, sounding a bit ashamed. "Well, it is weird!" You said. "I don't think this is a good idea at all. It's gross, even. You'd be using..." You said, before lowering your voice "My dick, to have sex? Doesn't that bother you? I still find it weird to even go to the toilet having to look at your... thing". You said, a bit upset at what your father was suggesting. "Oh, well... That part is going to be fine, I think. I've gotten quite used to it already. I mean, you know what I'm packing. It's good, but nothing like... You. or is that me, now?" He said before adding "Can you blame your old man for enjoying himself? And with this vigour! I'm enjoying myself three times a day." He said, excited. You now felt even worse. Your father more or less admitted to using your dick to masturbate. Three times a day at that. "What the fuck?" You exclaimed. "That's disgusting and even worse, why tell me? I do NOT give you permission to date using my body. I prefer it if you kept your hands to yourself, even." You growled. "Actually, I was just asking for permission to make myself feel better about it. Even better if you had been fine with it. But I'll be going through with this anyway. The girl is quite the babe by the way. I really hope I'll get some action. You know what? I'll send you some pictures she sent me. I think you'll understand your old man if I do" he said as he hung up.
"What the actual fuck!" You screamed. Your father was a little bit to fine with all of this. Using your body to have sex? Your phone buzzed. It was your father. He had sent you a picture. It was a picture of a conversation with some girl named Ellie. What greeted you made you even madder. He had cut most of the conversation, so you didn't see much of the actual texts, mostly two pictures. The top picture was beneath a text from your father that read "Damn, more please?". A picture of what you assumed was Ellie, in her bra and panties. Showing her tits. What's worse, she was a babe. You felt yourself get hard looking at her. But the bottom picture was the reason you got so mad. It was a picture of you. The old you. The body your father was now in for the coming year. Naked and erect. With the text "Fuck, look how hard you make me" underneath. Ellie had clearly liked what she had seen as she had written "want to meet up?". Your father had been you for little more than a week and was already well on his way to get his new dick wet. It made you mad. But worse, it made you horny. Knowing your dad was going to use your large dick to fuck Ellie's young pussy. Having her scream his name as he used your young body to pound away at her flesh. You calmed yourself as best you could. And your mother knew? Why didn't she say something about this? So you could have stopped it.
You decided to confront your mother about this. Ask her how much she knew about it. She said more or less what your father had said. She also decided to mention she might not be home every night. If she also found herself someone to enjoy herself with. Maybe she'd try Tinder, she said. You were so mad you went to your room. You probably laid there, on the large king sized bed, for hours. Your phone buzzed. It was midnight. A text from your father. "Damn, Ellie is freaky. Bet she'll let me record her. I'll send you the video if you want!".
"NO!" you replied. You sure as hell didn't want a video of your father using your cock to have sex. Had something happened during the procedure? Or was this part of it? Had he already started to go mad being his own son? Would you go equally insane? Now you were both mad and worried. You got undressed and decided to sleep it off. Thinking hard about the money you'd earn. It was going to be a long year.
Bzz! Bzz! You had fallen asleep and the sound of your phone buzzing woke you up. It was a little past 2 in the night now. A text from your father. A video was attached. You knew you shouldn't open it, but for some reason, you just couldn't stop yourself. It was a video, filmed in a POV you knew well. Your POV. Your old POV, now your father's POV. His large cock fully erect. Ellie's mouth wrapped around the head. "Oh fuck, you're so good at that" your father said. "Fuck, suck MY young fat cock!" he said, quite aggressively. But Ellie seemed to like it. This kept going for a while, your father kept repeating how it was his hard cock, his sexy young body. How hot Ellie was. All of a sudden, he pulled his dick out of Ellie's mouth and pushed her down on a bed. Ellie eagerly spreading her legs. "I want your fat cock in me" Ellie said. As your old cock found it's way into Ellie, your father again started talking about his new dick. "You like that fat cock, don't you? MY fat cock? Say it, say you want MY big dick". At this point you realized you were rock hard. Another text popped up on your phone. "Like what you see, dad? Bet you're jealous you ain't got a cock like mine!". Your father was now taunting you. Calling you dad. Which for some reason, made you even harder. You were being cucked by your own dad in your body, and you liked it? What the hell was going on?
You looked down on your fat stomach, your smaller penis. You grabbed it. You started masturbating. You didn't care that the penis used to be your dad's. You wanted to wank it. Thinking about how good it would feel if you were young and hung. Hell, you knew how good it felt. But you couldn't help feel like you also didn't. After all, you weren't young. You weren't hung, merely average. You were now looking at the video on repeat. "Damn! This is wrong!" You said. But what you followed it up with made you scream internally in horror. "It's wrong of me to look at my son having sex!". What? You referred to your dad in your body as your son. This was bad. You definitely had to tell the doctors at the next check up. They had to do something. "Damn, I'm getting jealous of my son". You did it again. Yet you didn't stop yourself nor did you stop masturbating. You looked down on your borrowed penis. Yet it didn't feel borrowed. It was your penis, not your dad's. "Fuck, my penis is about to erupt!" You exclaimed. With that, you came hard. Really hard. It felt really wrong. But you also liked it? You were definitely going to masturbate to that video again. Watching your son's large cock fuck a tight pussy as you stroked your own smaller one. Again! You called him your son again. But he's your dad. Yet it felt wrong calling him dad. You were the fat, old dad. He was the young attractive son. With the large cock. You really needed to talk with the doctors. Soon. Something was happening with your mind and it was hitting you hard and it was hitting you fast. You picked up your phone again. Wrote a text to David... or should you call him John now? Your mind felt heavy. "John... Don't send this kind of stuff to your dad. I don't want to see it!" you ended up texting. Damn, you had tried calling him dad. Calling him David. Yet you hadn't. You went into the bathroom and cleaned yourself up as you felt shame wash over your body. Was this how things were going to be for a year? You wouldn't be able to handle it. You felt terrible. So terrible in fact, you had to rush to the toilet and throw up. How the hell would you come back from this?
