Caitlyn and Joey argue

Caitlyn hurried down a few minutes later, freshly showered, her bare skin glistening.

“Going nude, honey?” Liz asked our daughter, mildly surprised. Liz had always been slightly disappointed that none of our kids had followed her example and become nudists, but as a merely casual, at-home nudist herself, she’d never really tried to push it very much.

“I thought it’d save some time,” Caitlyn explained, giving her mother another apologetic smile.

“Oh, I see,” Liz said, and let it let.

Joey grinned at his older sister’s huge, exposed tits, but Caitlyn slepped his hand away when he made to reach over and fondle one of them.

“No touching at the dinner table,” she told him.

“Since when?” Joey asked, disappointed.

“I want to eat in peace and get all the food in my mouth for a change,” she told him. “But I’ll make you a deal: no trying to grope my tits during dinner, and I’ll let you fuck them after. Deal?”

Joey’s face lit up. “Deal!” he agreed with gusto.

Tina grumbled. Among other things, her big sister’s enormous endowment was yet another source of jealousy for the small-chested teen.

I was worried about Tina. She was a gorgeous young woman, and smart, with a winning personality, but her bad habit of comparing herself to her older sister didn’t help her confidence at all. And although up until now I’d done my best to reassure her of her own excellent qualities by praising them when I made love to her, Liz’s insistence that that attention had resulted in Tina becoming too fixated on me worried me. Maybe she did need to hear more praise from boys her own age who were interested in her, without the chance to cloud the issue with jealousy of her older sister when I inevitably paid attention to my other daughter as well.

After dinner, while I helped Liz clean up the dishes, I could hear Caitlyn admonishing Joey in the living room, “Now warn me before you cum!”

“Absolutely, sis,” Joey assured her, and then I heard the telltale soft slapping noises of a cock thrusting between two big, soft breasts.

As Liz and I were finishing up with the last of the dishes, I heard Caitlyn angrily exclaim, “Joey!” A minute later, our eldest daughter burst into the kitchen with a faceful of cum, one strand of which ran up over one closed eye and into her gold hair.

“Daddy,” Caitlyn addressed me frostily. “I’m going to go upstairs and wash my face. Can you have a talk with your son, please?” And with that, she spun on her heel and stalked off.

Liz looked at me with one raised eyebrow.

I shrugged. “I’ll talk to him,” I promised, then dried my hands on a dishtowel and left the kitchen.

I found Joey sitting on the couch watching television. His dick was still out, oozing a last little bit of cum while he stroked it slowly as he watched some couple fucking on the sitcom he was watching, a bit limp after just cumming on his sister, but slowly working itself back to erection.

I sat down on the couch next to him and got my own dick out. This talk might go a bit better, I thought, if it was a friendly chat between two guys enjoying a leisurely jerk-off while watching some sex of TV, instead of a stern parental lecture.

“Your sister was a bit upset, son,” I remarked casually as we sat and jerked off, watching the couple on TV fucking.

“Yeah, I know,” Joey replied, just as off-handedly.

“You don’t think that’s a problem?” I asked. “She may be just your sister, but if you act that way with other girls, you’re gonna get real unpopular, real fast,” I warned him.

Joey laughed. “Don’t worry, Dad,” he assured me. “I know how to be polite about cumming on a girl. I only do that with Caitlyn.”

I looked over at him with surprise. “What? Why?” I asked.

“Because it winds her up so much,” Joey chuckled.

I shook my head and sighed, though I couldn’t help but chuckle. “You shouldn’t tease your sister,” I admonished my son, although it was half-hearted. I could remember growing up with my own sister, Brigitte, and goosing her by surprise every chance I could, no matter how many times she berated me for it. It had never stopped her from coming to me for blowjob “practice” practically every night until I’d finally moved out to go off to college. I guess sibling rivalry was too ingrained in human nature for any mere father-son talk to work it out.

“Okay, kid,” I finally said. “Tell you what: tease her if that’s what you’ve gotta do, but do one thing for me, okay?”

“What’s that, dad?” Joey asked, although he was getting distracted as he jerked his cock off harder and faster, his eyes glued to the fucking couple on the screen as her got closer to cumming.

“Wait a little while, then go upstairs and offer to eat Caitlyn’s pussy as an apology,” I suggested. “Not as foreplay—don’t ask to fuck her after you get her wet. Just eat her out until she’s had enough and tells you to stop. I promise, she’ll forgive you for cumming in her eye.” I promised my son. “She may even forgive me for convincing her to let you do it,” I muttered under my breath.

“Okay, Dad, I will,” Joey agreed, but his voice was strained and his eyes were shut as his hand flew up and down on his dick like lightning. A moment later, he arched his back well off the couch, and five or six spurts of cum burst out of his dick and plastered his shirt.

“You shouldn’t cum on your shirt like that, son,” I chided him. “You know how hard cumstains are for your mom to get out. Take your shirt off next time, or at least pull it up, or cum into your hand, or something,” I advised.

“Okay, Dad,” Joey agreed, panting as he caught his breath. “What about you? You gonna cum?” he asked curiously.

“Nah,” I said, shaking my head. “Not gonna waste it jerking off. I’ll go find your mom in a couple of minutes.”

“Right on, Dad,” Joey said, offering a hand for me to high-five.

I snorted and shook my head, but gave my son the high-five anyway before I stood up, hard-on swaying from my crotch. “Probably won’t be back out tonight. See you tomorrow, son,” I told Joey, and held my arms out for a hug. “It’s good to see you back home. Tomorrow you’re gonna have to tell me all about why your trip fell through.”

“Not in the morning,” he told me with a wry grin, standing up to give me a hug. “I’ll be sleeping in.” With both of our dicks still out, my hard-on poked right into Joey’s own hanging dick when we hugged. To my surprise, I felt his dick give a quick lurch and swell slightly at the contact.

To my knowledge, Joey had only ever had girlfriends. Was he starting to feel more bi-curious now that he was away at college, experimenting more freely with other college kids and professors, away from parents and the structured life of high school? That would be good, if it was true. It wasn’t healthy to stick with just one gender in one’s sexual partners, without at least experimenting with other genders to really explore one’s own orientation fully before settling on anything specific—if you ever did settle on anything.

“Good night,” I wished my son, and left him to head upstairs and find Liz. It was only nine o’clock, but like most nights, I expected we would fuck for an hour or two, then watch some TV in bed before having a final screw and going to sleep.

Little did I know, that would be the last night I spent fucking my wife for months. Things were about to get complicated.
