We were walking and talking...

The next day, Gary and Hank were walking together in the trees in the lower part of Gary's college campus, talking about what had happened after Hank had walked in on his son Gary dicking his friend Peter up the ass over the desk in Gary's bedroom.

"It's natural," Hank said. "It runs in the family. And it doesn't mean you can't have girlfriends or whatever. What it does mean is that you have to be extra clear with your best girl. That it has to be okay with her. And you have extra careful about safe sex. All that's just the same as if you had another girlfriend."

"It runs in the family?" Gary said.

"Yup. Not just you and me," his father said.

Gary raised his eyebrows. "Who?" Last night his dad had talked about him and his high school buddies, but hadn't mentioned anyone else.

Hank sighed. "Your uncle Ned," he said. "He and I were a little like you and Peter, I guess. I gave it up when he left for college, but like I told you last night, I started up again after your mom and I joined up with a swingers' group."

"Is that pretty much where you do it with guys?" Gary asked.

"Pretty much," Hank said. "Like I said, not every time. Your mom and I also have some friends we met through the group that we get together with outside the parties."

They walked for a while through the trees, quietly.

"Thanks for last night, dad," Gary said. "I mean, like, talking straight with me. And showing me the picture book. And your favorite picture."

"You're welcome, Gary," Hank said. "And thanks for letting me hold your cock."

Gary shivered, feeling excited but uncertain. "Yeah. And thanks for letting me hold yours. T-too bad I didn't get to see you come."

"Did you want to see that, Gary?" Hank said.

"Yeah, dad," Gary said.

Gary cleared his throat and nodded to Joyce. "Yeah, so Dad and I were talking about what happened that night," he said. "And Dad had seen me come twice. And you know, I had my hand on his cock but I didn't get to see him come. So he asked if that was what I wanted and I said yes. And I had the van parked out there on the far part of campus where there's not much there yet. And I guess Bernie saw me and went up to Stuart's van, and when she got there...

Hank lay back nude on a towel in the back of Stuart's Super Surf Van as his equally nude son Gary kneeled between his legs. A condom wrapper lay discarded to one side, its contents now covering Hank's erect penis.

Gary was doing his best to suck his dad's large, thick cock. When Gary sucked his friend Peter, he could take in about half Peter's shaft, but with Hank, Gary could take in little more than the broad head.

Hank coached Gary to take him deeper, until he could see Gary was having trouble. "Okay, good enough for today," he told Gary.

Gary sat back and breathed deeply. "Wow," he said.

"You wanted to see me come?" Hank said.

"Yeah," Gary said.

"Lay back," Hank said. He took another condom, dribbled lube inside the tip, pulled on Gary's shaft to retract his foreskin and rolled the condom over Gary's penis down to the blond pubic hair. Like Hank's own penis, Gary's had a large head that was a little tricky to get over.

Hank drizzled lube over Gary's cock and got into position. He reached down to steady Gary's penis and sat down on top of Gary's erection before Gary figured out what was happening.

"Fuck, dad!" Gary cried out in surprise as his cock entered his dad's ass.

Hank let out a groan as his son's big cock slid up his ass. Gary's erect penis was bigger than Hank's usual male partners and had a young man's extra firmness, but he wasn't too-too big. Hank smiled. "Don't go anywhere for a minute," he said. Hank stripped off his condom and started stroking his cock, sliding his foreskin on and off the head. Sometimes Hank had to work to stay hard while he was being penetrated, and he wanted this to look good for Gary.

"So I guess Bernie told you what she saw through the window of Stuart's van," Gary told Joyce.

"Mm-hm," his girlfriend's nude mother said from her chair. "She did. She thought about you and your dad being sexual together and decided that it was all right. Since, Naomi, pardon me, Bernie and I are sexual together and she often sees family members be sexual together at my Pleasure Circles. The only things she asks are your complete honesty, good safer sex practices, and that she's there with you when you're sexual with someone else. Like your father or your friend Peter. When she's there with you, your pleasure will be hers too."

Gary swallowed. "Okay," he said. "But didn't you and I just...?" He waved his hands, indicating the two of them sitting nude in her living room after masturbating together. "Without her?"

"I suggested it would make you more comfortable, and she agreed," Joyce said. "But I do enjoy watching you masturbate, and I hope we'll be able to do it together with Bernie sometime soon. She accepted my apology for the night after the Billy Royce concert."

Gary recalled that Joyce had insisted he masturbate openly that night in her car rather than fidgeting around in his pants after making out with Bernie. And Joyce had masturbated too, watching him.

Joyce continued, "We've agreed that it's all right for me to watch or masturbate with you if you're visiting the house or if you're at a Pleasure Circle."

"Oh." Gary said.

"And we both agreed that if you and your father want to be sexual together, you can come here any time," Joyce said. "It's a rather unusual connection, in my experience. You would be welcome here."

Gary coughed. "I guess I'll tell dad," he said. "Dunno if it'll ever happen again. You know."

Gary thought back to what Bernie must have seen that day.

Hank stroked his cock as he moved slowly on top of Gary's penis. His heavy balls had risen and were now tucked tightly against the base of his shaft. A faint wet noise came with each stroke as his thumb stroked the foreskin off his glans and on again. He sighed as the head swelled.

Gary gasped as he felt his dad's ass squeeze down on his cock. "Ah!" he cried out.

"Here comes, Gary," Hank said.

"Huh?" Gary said.

"What you wanted to see," Hank said. He took a deep breath and pushed back, taking his son's thick cock deeper, then rose on Gary's shaft till only the head was inside his anal ring. "Ah," he sighed, stroking steadily. "Ah."

Gary felt his dad's ring squeeze down tight under his cock head. From many times having his cock in Peter's ass, he knew what was coming. His eyes focused on the slit at the tip of Hank's big cock head.

"AH!!" Hank cried out. White semen lanced out from his penis, splashing in hot wet lines across Gary's chest. He kept riding Gary's cock, head-deep as he came, ejaculating with each pulse and squeeze in the ancient four-fifths-second rhythm.

Gary felt the friction and squeezing right under the crown of his cock head and couldn't help following his dad up and over the top. Gary's cock swelled inside Hank's rhythmically clenching ass. Gary's body tensed, he thrust his pelvis upward, moaning and crying out as he blasted off inside his dad's ass.

Joyce cleared her throat and Gary met her eyes. He wondered how long they'd been naked together in her living room. Maybe an hour? But Joyce liked to go nude at home. Especially on a hot day like today.

"Remember, when Bernie gets back from the mall with your sister, you have to tell her that you have two male partners you're sharing fellatio and anal intercourse with, your friend Peter Walker as well as your father," Joyce said.

Gary swallowed nervously, but nodded. "Okay."

Joyce smiled. "Don't forget, when the time comes you can ask her if there are sexual things she would like to try with you. Since you told me she'd never asked you to pleasure her anally."

"Oh," Gary said. "Right. Too shy? I mean I wouldn't want to put her off."

"You've been very good to my daughter," Joyce said, "and I think you can be good to each other. As long as you're honest and loving and understand each other."

"D-does Bernie have any other lovers? Or anyone she has sex with? I mean, besides you?" Gary asked.

Joyce paused, as if considering whether to let her daughter be the one to answer instead.
