*****

My son Liam had celebrated his 18th birthday early in his senior year of high school, and now, nine months later, it was hard to believe he was graduating from high school. I know he was excited to move off to college in the fall and enjoy his independence, but he was also sad to be leaving his boyfriend, Justin, who was the same age as Liam but was going to a different college.

Justin and Liam had been best friends since they were kids, because I was best friends with Justin's dad, Chris. Chris and I were both divorced single dads and had gotten to know each other through our kids' school events. Chris was the coach of the high school's soccer team, which Justin played on and Liam cheered for. That's right - Liam had gotten a spot on the cheerleading team, and he fit right in. This didn't bother me, of course - I loved my son no matter what. I knew he was gay probably even before he did, and when he finally came out to me when he was 15, I just gave him a hug and told him I supported him. I was a little nervous about him getting bullied at school, but he actually seemed to get along really well with everybody - I think Justin helped to make sure a lot of the jocks at school weren't mean to him, which I was grateful for.

Chris and I had suspected for a while that Justin and Liam were more than just friends, and it was confirmed when, one night, we caught them in Liam's room making out. They were embarrassed, but Chris and I just told them we were happy for them, that they made a great couple, and gave them a little talk about being responsible. They seemed to understand.

Now, the summer before they went off to college, they were both trying to be mature about the fact that they would be moving off to different places, but Chris and I could tell they were pretty sad to be leaving each other. It was cute, to be honest.

One night early that summer, Chris and Justin came over to our place for dinner. After we ate, Justin and Liam went upstairs to Liam's bedroom. Chris and I knew they would probably be fooling around a little, but as responsible dads, we made them keep the door open so that we could make sure nothing got out of hand. Meanwhile, Chris and I sat in the living room and watched a basketball game.

As it got late, Chris and I went upstairs to let them know it was time for Chris and Justin to head back home. As we walked down the hallway, we heard Liam and Justin talking. Chris smiled at me and put a finger to his lips, gesturing for me to be quiet so that we could eavesdrop. I grinned back and nodded. We carefully approached the bedroom and stood outside the door so that they couldn't see us. We very quickly popped our heads in and saw them lying down next to each other on Liam's bed, on their stomachs watching the TV that was at the foot of the bed, so that their backs were to us. We ducked back out so they wouldn't see us.

"It's gonna be sad leaving you," we heard Liam saying, "but at the same time, college is gonna be, ummmm, a lot of fun, ya know? All those cute college boys!"

They both giggled. "I can't imagine you being any more of a slut than you already are," Justin said, making them both laugh again. Chris and I looked at each other, a little stunned to be hearing this.

"I'm not a slut, I'm just...uh...boy crazy," Liam said, giggling.

"Oh, sure," Justin said. "Are there literally any guys on the soccer team who haven't fucked you this past year?"

Liam gasped in fake shock and we could hear them wrestling around on the bed a little. It sounded like Liam was tickling Justin. Between laughs, Justin cried out, "What? It's true, it's true!"

They stopped their wrestling and Liam said, "Shhh, shh, we're getting too loud." Chris and I stood frozen, looking at each other with concern at what we were hearing. There was a pause, then Liam said, "Besides, those guys probably would have bullied me if I hadn't ridden their cocks so good, so..." They both burst out laughing.

I couldn't believe what I was hearing. My son, a slut? Images of the guys on the soccer team taking turns fucking my son involuntarily flashed through my mind. I looked at Chris, who was looking back at me with concern. I was about to walk in the bedroom and announce it was time for Chris and Justin to be heading home when they started talking again.

"There is one guy who is technically a member of the team who hasn't fucked me, but I really really really wish he would..." Liam said.

"Huh? Who?" Justin asked.

"Um..." Liam paused, holding back laughter. "...the coach."

"Oh my god, gross!!" Justin said, stunned but still laughing. "That's my dad!"

I looked at Chris. His jaw dropped open.

"I know, I know, I'm sorry, that's weird," Liam said, "but, like, you have to realize how fucking hot your dad is, right?"

There was just stunned silence from Justin, then embarrassed laughter. "Oh my god, Liam, I can't believe how slutty you are."

"Oh my god, whatever," Liam said, "you know he's hot. I love those shorts he wears during games, you can kind of see the outline of his dick sometimes."

Chris's face was bright red with embarrassment. Mine must have been too.

They just laughed and lay there for a moment. Then Liam asked, "Do you, like, get to see him shirtless a lot?"

Justin laughed again, embarrassed. "Oh my god, Liam!"

"What, come on, just tell me," Liam said.

"I mean, like, he usually works out in the basement shirtless and I'll see him when he's done and he's going upstairs to take a shower," Justin said.

"Oh my god, all sweaty??" Liam said, excited. "I'm soooooo jealous of you, you must jerk off all the time with him walking around like that." Justin must have looked at him in a certain way, because Liam then said, "Oh my god, you do!!" and started laughing.

"I mean..." Justin said, "...if he weren't my dad, I would definitely think of him as hot."

"What does he look like shirtless?" Liam asked.

"Umm..." Justin said, clearly a little uncomfortable but also excited. "He's got like a little bit of hair on his chest, and a line of hair going up to his bellybutton, and...like...I dunno..."

He broke down laughing in embarrassment. Liam laughed too and said, "Oh my god, come on, what?"

"I mean, he's just, like, very muscular," Justin said, giggling. "He's got six-pack abs and...I dunno...just a really nice chest."

"Oh...my...god," Liam said, "you've got the hots for your dad."

"I do not!" Justin said, laughing. "I just recognize that he is an attractive guy."

"Yeah, whatever," Liam said.

"Your dad's not too bad either," Justin said.

Liam giggled. "I mean, yeah, he's pretty cute, I guess."

I couldn't believe what I was hearing. My son and his best friend were talking about whether I was attractive.

"Um..." Liam said, clearly wanting to say something but holding it back.

"Come on, what?" Justin pushed.

"One thing about my dad is..." Liam began, then paused again.

"What?" Justin asked.

"Um...I've seen his dick, and it's, like, huge," Liam said.

"Oh my god!" Justin said. "That's...so fucking hot. How did you see it?"

"Sometimes he leaves his bedroom door open a crack when he's changing and, um, I've taken some peeks," Liam said, giggling.

"Like...how big is it?" Justin asked.

"I dunno, it's always soft when I see it, but I would guess that when it gets hard it's probably like 8 inches or so," Liam said.

"Wow..." Justin said dreamily. "I would suck that thing so good."

They both laughed, and Liam said, "Oh my god, gross."

They paused again, then Liam said, "Fuck, I want your dad to fuck me so bad," and they both burst out laughing.

"Too bad it's never gonna happen," Justin said, "you'll just have to make do with me for now."

Then we heard little moans as they started to make out. Chris and I looked at each other in shock at everything we had just heard. He motioned for us to go back down the hall, which we silently did, then Chris started loudly stepping back down the hall toward their room and called out, "Justin! Time to go!"

We heard them giggle a little, then Justin called out, "Okay, Dad!"

We walked the rest of the way down the hall and stood in the doorway. Justin was sitting on the edge of the bed, putting his shoes on, but Liam was still sprawled out, lying on his back. I wouldn't have ordinarily noticed this, but I saw that his t-shirt was pulled up a little, revealing his smooth stomach and the band of his underwear.

"Thanks for letting Justin hang out tonight," Liam said to Chris, smiling up at him. His hand played with the bottom hem of his t-shirt, casually pulling it up a little higher.

I saw Chris glancing involuntarily at Liam's stomach. He stood there awkwardly for a moment, looking nervously around the room, then said, "Uh, yeah, no problem, Liam."

Justin looked over and saw what Liam was doing. He looked surprised, then stifled laughter and shook his head at Liam's audacity. "Okay, see you later, Liam," he said, giving Liam a peck on the cheek then walking out with his dad.

The three of us walked downstairs to the front door. Chris and I awkwardly shook hands. "Um...so...have a good night, guys," I said. "See you later this week sometime?"

"Uh, yeah, for sure. Good night, Ben," Chris said to me. He was clearly in a state of shock.

They left, and I stood at the door, not sure what to do. After a minute, Liam called down to me, "Good night, Dad!"

"Good night!" I called back up to him.

I was stunned by everything I had heard, but as I stood there, I also became increasingly aware of the raging erection that was pressing against my jeans. I was embarrassed to be so turned on, but I couldn't deny that the conversation I had just overheard was really hot.

I watched TV for about an hour, trying to take my mind off things. Finally, I walked upstairs and down the hall to my bedroom. On the way, I poked my head into Liam's room. There he was, lying asleep in his bed in just a pair of red briefs - he always slept in just his underwear, and it was a hot night so he had tossed his sheets off as he slept. He was lying on his stomach, his legs spread out slightly. I had truly never thought of my son sexually before, but after hearing the way he had been talking with Justin, I couldn't help but stare at his tight little butt as he lay there. My raging erection was back, and I grasped it lightly through my jeans as I stood there.

It took all my willpower not to step into the room and give his butt a little squeeze. Instead, I walked down to my bedroom, stripped off my clothes, and got into bed. I couldn't help but jerk off, sexual images of Chris, Justin, and Liam flashing through my mind. It was one of the most powerful orgasms of my life.

***

I woke up the next morning to a text from Chris. It read, "So...that was an interesting conversation we overheard last night."

I didn't know what to say, so I just texted back, "Um...yeah, for sure." We continued:

--

Chris: I guess we shouldn't be too worried. When I was a horny teenage boy I had all kinds of inappropriate sexual conversations too.

Me: That's true. Just kind of shocking to hear our own sons being so explicit.

Chris: Definitely. And just so you know, I was totally surprised to hear that Liam...uh...gets around so much with the other guys on the soccer team. If I had any idea, obviously I would have put a stop to it and let you know.

Me: Of course. Although, he's technically an adult and can make his own decisions.

Chris: True.

--

We left the conversation there. As I stepped out of my bedroom to go to the bathroom, across the hall, Liam was just leaving the bathroom. He was still wearing just his red briefs. I couldn't help but look at him in a different light. Liam had blond, slightly wavy hair, and was short and slim. Justin - who had dark brown hair and was a little taller and more muscular - was always calling him a "pocket twink." I looked him up and down, taking in his smooth body, his flat stomach with little hints of a six pack.

"Um...you okay, Dad?" he said, smiling as he looked at me staring at him.

I felt myself blush, and said, "Um, yeah, I'm fine," then rushed into the bathroom.

Later that day, Liam asked if we could order pizza and have Justin and Chris over again. I said sure. Liam was wearing a tight pair of shorts and a tight-fitting gray tank-top. I couldn't believe I was feeling this way, but he looked really sexy.

That evening, Chris and Justin arrived at our front door. Justin was wearing a soccer jersey and a pair of shorts - pretty typical for him. I was a little surprised to see Chris wearing a sleeveless muscle shirt that showed off his muscular arms. The arm holes were even cut low to reveal the sides of his torso, so that you could see a hint of his pecs and abs.

"Hey, Ben," he greeted me. "Sorry, I just got done working out and didn't have time for a shower, hope it's ok."

"Um, yeah, no problem," I said.

As they walked into the living room where Liam was sitting on the couch, Liam's mouth fell open when he saw Chris. His ogling was so obvious that Justin couldn't help but laugh. "Hi, Liam. Everything okay?" he said.

Liam smirked at Justin. "Everything is just great. Hi, Chris," he said, kind of shyly.

"Hey, Liam, how ya doing?" Chris said, walking over to him with a smile. Liam got up and gave Chris a hug. As they separated, Liam was not very shy about letting his hands move across the parts of Chris's sides that were exposed by the muscle shirt.

"I'm very good," Liam said, biting his lower lip unconsciously. Chris sat down on one end of the couch, and Liam sat down next to him.

I really couldn't believe that Chris had chosen to wear this outfit given the conversation we had overheard last night. It seemed almost deliberate. But did that mean Chris was having the same aroused feelings I was having?

As Justin sat down on the couch next to Liam, I saw him glancing me up and down a little bit. "Um, Ben, I like those jeans, are they new?" he asked me.

I looked down at my jeans. I had happened to put on my favorite pair, they were somewhat tight-fitting and I thought they looked good on me - although you could kind of see the outline of my lengthy penis running down one leg. "Oh, uh, no, I've had these for a while," I said.

"Oh," Justin said, continuing to stare. "Well, they look really good."

Liam giggled. Embarrassed, I sat down in a chair next to the couch.

We turned the TV onto a basketball game and made small talk for a little while.

"So can we order the pizza from Antonio's, Dad?" Liam asked.

"Mmm, that sounds great," Justin said.

"Oh, come on, guys, you know they don't deliver. I'd have to go pick it up," I said.

"I'll go with you to pick it up if you want some company," Justin offered.

"Please, please, please? It's so much better than any of the places that deliver," Liam said, clasping his hands together like he was begging.

I looked at Chris. He looked a little preoccupied by the way Liam was bouncing up and down on the couch as he "begged." But then he seemed to shake himself out of it and turned to me, saying, "It is really good pizza..."

I sighed. "Fine...you order it, Liam."

Liam smiled and got on his phone to place the order. After a minute or two, he said, "Okay, it says it will be ready in an hour. Thanks, Dad!"

We sat watching TV for a little bit. I noticed Liam had put his arm around Justin, who was leaning in to rest his head on Liam's chest. This wasn't unusual for them, we had always made sure they felt comfortable expressing their affection as long as it was appropriate. In this case, their cuddling seemed to push Liam into Chris a little bit, so that Chris and Liam's arms were touching and Liam's head would occasionally rest up against Chris's shoulder. I thought this was a little weird, but it seemed to have happened naturally enough.

After a few more minutes, Justin said, "You guys always put the air conditioning on so high, it's too cold! Do you have a blanket or something?"

"Sure," I said, and handed Chris a blanket that had been draped over the back of the chair I was sitting in.

"It is a little cold," Chris said, "Do you mind if we share?"

"Sure, that's ok with me, Chris," Liam quickly answered, unfolding the blanket with Chris and placing it so that all three of them were covered up from the waist down. Chris propped his feet up on the coffee table in front of him, then casually brought his arm up, resting it on the back of the couch, which caused Liam to lean over into Chris's shoulder a little bit to get comfortable.

I looked at Chris, who looked back at me with a kind of weird expression on his face. He bit his lower lip nervously and gave a little shrug, as if to say "no big deal." But obviously we both knew what we had heard the night before, and now Chris was letting them cuddle right next to him while they were all under the same blanket.

Meanwhile, Justin giggled a little and said, "Um, are you comfortable, Liam?"

Liam giggled back. "Yes, thanks, I'm sooo comfortable. Is it ok that I'm leaning on you like this, Chris?"

Chris blushed a little and looked over at me. "Um, I mean, sure, it's ok with me if it's ok with your dad..."

Liam looked confused. "Why wouldn't it be ok with him?"

"Oh, um...yeah, you're right," Chris said, fumbling over his words. "No reason."

"Right, daddy?" Liam asked.

I was caught off guard by Liam calling me "daddy," which he didn't usually do. I looked at Chris, who was looking back at me very intensely. "Um...yeah, of course, it's fine," I said, trying to sound casual.

"See?" Liam said to Chris, then nuzzled in more closely into Chris's chest. Chris started slowly moving his arm down so that it was wrapped around Liam, his hand on Liam's bare shoulder. Chris was looking at me the entire time he did this, gauging my reaction. I just sat there wordlessly, my mouth slightly agape.

We kept watching the game. After a few minutes, Justin got up, saying he had to go to the bathroom. With Justin no longer cuddling Liam, Liam moved himself around a little bit to be leaning even more comfortably against Chris's chest. His hand was resting lightly on Chris's chest. I could see Chris taking slow, shallow breaths, keeping his eyes frozen on the TV, pretending like nothing was happening but clearly getting worked up.

I sat, watching what Chris and Liam were doing out of the corner of my eye. I saw Liam's hand move ever so slowly down Chris's chest, resting on his stomach, then move slowly under the blanket. I kept my eyes glued to the TV so that Liam would think I wasn't watching what he was doing, but I could definitely see that his hand had moved down to the area of Chris's crotch. Chris's face was trying not to show any reaction.

I was simultaneously really concerned and really turned on. Out of the corner of my eye, I could see that Liam's hand was definitely moving around under the blanket, although it wasn't clear exactly what was going on. Chris would keep Liam from doing anything really inappropriate...right?

When Justin came back into the living room from the bathroom, he froze in place when he saw Liam's hand moving under the blanket. "Oh my g-" he started saying, then looked over at me and quickly suppressed his shock. "Uh, I mean, um, how's the game going?"

I looked over at Chris and Liam, and the movement under the blanket quickly stopped. "It's good," Chris said. He was clearly trying to sound casual but his voice betrayed his excitement and nervousness.

Justin sat down next to Liam and started cuddling with him again. He was now leaning on Liam's chest, who was leaning on Chris's chest, Chris's arm now holding Liam tight against his muscular body. It was now obvious something was going on under the blanket - was my own son giving my best friend a handjob right next to me? I knew this was all really wrong, but I couldn't bring myself to put a stop to it as my hard cock strained against my jeans.
