Chapter 1

Tim and Lizbeth raised their three children as nudists, and to be openly sex positive. But when their youngest son, Garrett, asked his dad if his best friend, Mark, can come over and have sex, it gave the couple pause. They looked at each other over the tops of their glasses from where they sat, nude, at the kitchen table sipping coffee as they read the newspaper. Tim arched his eyes and Lizbeth shrugged in agreement.

“Sure, son. This is going to be a first for you, isn’t it?”

“You mean having sex with a guy friend? Yeh, it will be. Me and Mark have been checking out the gay porn sites you turned me on to and decided we’d like to explore our bi sides, with each other.”

Garret and Mark had been best friends since grade school. With Mark’s parent’s consent, Mark had joined the Loewens on their annual nudist hikes in the mountains. There was nothing that Garrett and Mark didn’t talk about or do together, so Tim thought it natural that when his son wanted to explore his bi side, Mark would be a great sex partner.

“That’s great, son. I don’t know how far you plan to go, but you have plenty of condoms and lube, right?”

This question brought a smile and a playful eyeroll from recently 18-year-old Garrett, who despite his young age could teach classes in sex ed. Tim knew his son and Mark would be in for a good experience because he and Lizbeth had raised their kids right when it came to both body image and sharing their positive attitudes about sex. Their kids also knew they were non-monogamous and had met many of both their parents’ outside sex partners.

Garrett sat nude on the living room couch, feet set apart so one could clearly see his ample sex organ hanging between his legs, semi-hard. His eyes were focused on his phone as he texted the good news to his friend that they had the green light to meet at his house and fool around. Garrett was slender and dark complected and had stunning good looks which he inherited from his Irish-German dad and Latina mother. He also inherited his dad’s rather large endowment which looked even bigger set in a full, dark bush when jutting out from his skinny, but fit, hairless body.

“Dad, one other thing,” Garrett said looking at his dad with a smile. “Can we screw right here in the living room?”

This brought another non-verbal consult between the parents ending this time in a simultaneous shrug. Tim responded, “Why not?” Tim and Liz knew that once they were adults they told their kids they could have sex in any room of the house, just like the other adults did, and Mark’s older brother, Nate, banged his girlfriend openly all the time. Liz reminded Garrett to put towels on the furniture like her and Tim were used to when they had sex parties so as not to get body fluids on the furniture. They also knew their younger daughter, Chrissy, was at cheerleading practice and was spending the night with family friends at a girls’ slumber party.

“Sure thing,” Garrett replied, knowing the drill from helping his mom prepare for their parties.

“After masturbating in my room for years, I’m looking forward to having sex out in the open like you guys do, and joining in the adult sex parties.” This last statement brought one more silent consult and shrug from the two parents who knew this day would come, just as it did for their older son, Nate. Nate had become a celebrity of sorts at the Loewen’s sex parties.

Just then, the doorbell rang and it was Mark, who rode his bike the short distance between their houses. Garrett ran naked to the door to let Mark in giving his shirtless and barefoot friend a hug. All Mark had worn for the ride over was a pair of loose-fitting shorts, commando, which he discarded once inside the door. Mark, also 18 and with a mop of long, curly, blonde hair, showed off a summer tan and full blonde bush surrounding his more than adequate cock. It was not as long as Garrett’s but thicker and circumcised, whereas Tim and Liz had left Garrett uncut.

Garrett invited Mark to go to his room first to play some video games and watch porn so they can get ideas of things they’d like to try later when having sex. Mark enthusiastically agreed and off they went to Garrett’s room. This gave Tim and Liz a moment to process what was happening.

“Our youngest son has grown up to be a man,” Liz said with an approving smile.

“Yes, and it looks like we’re about to see how years of the best sex education parents could offer will turn out when we get to see both of them in action,” Tim added.

“Garrett’s girlfriends seem pretty satisfied. I hope Mark will feel the same way. It’s just really amazing that these two longtime friends are going to help each other explore the world of man sex,” Liz continued, focusing on the strong bond of friendship between the two.

“There’s nothing better than having friends with benefits, especially at Garrett’s age, to help him mature sexually,” Tim concluded. “That’s how Allen and I started out back in college, and now he and his wife are our best bisexual swinger friends.”

Garrett then walked down the hall to the living room, leading Mark by the hand, which was sort of a tell as to what was going to happen later. Both boys had throbbing erections so it was obvious they had finished the video games and switched over to porn. Now, here they were, about to experience male adult sex with each other for the first time in either of their young lives.

As they both stood facing each other, Garrett held Mark and planted a kiss on his lips, which turned into a deep French kiss as their tongues played together, and Garrett ground his pelvis into his friend’s body. Things heated up fast as pounding hearts translated into throbbing cocks and Garrett started humping his penis into Mark’s crotch, basically frotting with the boy handsfree. It was Garrett who slid to his knees first to take his friend’s swollen, rigid manhood into his mouth.

Tim watched as Garrett pulled back the skin on Mark’s shaft, fully exposing his bulbous, red dick head. Mark was already showing a pearl of precum from his excitement, which Garrett instinctively slurped up. Garrett then licked all around Mark’s head, which seemed to swell even larger. Then, Garrett took the head all the way in his mouth, swirling his tongue around it before going down as far as he could on Mark’s shaft.

Mark yelped with delight. Then, placing his hands on Garrett’s bare shoulders, threw his head back as the pleasure overtook his body. Garrett now held Mark’s large ball sack in his hand as he started blowing his friend, sucking on the shaft and deepthroating him as best he could. Mark’s girth made it a challenge but on at least one occasion, Garrett was able to get him down balls deep, which Mark appreciated as he let out a moan.

Slobber was pooling on the tile floor when Garrett pulled his moth off Mark’s cock with a pop. Then smiling, said to Mark, “It’s your turn!” Mark eagerly knelt to return the favor holding his friend’s uncut meat in his hand as if to inspect it.

“Just do what I did to you and pull the skin back,” Garrett instructed his friend. Mark was glad to oblige pulling back Garrett’s hood and licking the cleft of his pee slit and right beneath it. This made Garrett’s knees buckle and he braced himself on the back of the sofa which was behind him.

“Holy shit! That feels amazing, dude!” Garrett complimented his friend on his first-time oral skills.

“Well, we jerked off to a shitton of those gay porn vids your dad shared with us,” Mark respionded.

“That’s true,” Garrett replied, as he arched his back and stood on his tip toes to get the best angle on the head his friend was giving him.

“I guess those were pretty instructional after all,” Tim interrupted. The boys seemed startled at the reality that they had an audience, even though they chose to do this openly. Both pairs of eyes shot in Tim’s direction, followed by two appreciative smiles and thumbs up for the videos he provided. Although it was super hot watching his son have his first gay sex experience, he didn’t want to interfere, but just be supportive.
