I woke up late the next morning with a minor headache and major regrets.
The headache was attributable to all the wine I'd drunk, the regrets to the fact that I'd had gay sex with my best friend.
Why, why, why had I done it?
I'm not gay, and until last night I never would have suspected that Jake was, either.
But when he'd come on to me, in the sexually charged atmosphere after our naked swim, I'd responded after only the briefest hesitation.
I tried to be mad at him for taking advantage of me while I was drunk and high, but I couldn't manage it. In my secret self I knew I hadn't been so out of it that I couldn't have stopped things if I'd really wanted to.
Why didn't I?
I made a stab at rationalizing my behavior:
A guy who lets another guy suck his cock is just taking advantage of an opportunity, because a mouth is a mouth, right? It doesn't necessarily signify anything deeper.
But if a guy sucks that other guy's cock in return, and eats that other guy's cum, he can hardly say he's a passive participant in the encounter, can he?
What unnerved me the most about my willingness to cross a boundary I'd never dreamed of crossing was that it came out of nowhere.
I could honestly say that until that moment in the lake when Jake's hard cock poked me in the side, I'd never seriously contemplated having sex with a guy.
But that one touch seemed to loosen something in me, some sexual impulse I'd either ignored or suppressed.
That I might actually be gay seemed unlikely, given my longstanding attraction to women, which I had no doubt was genuine.
That I might be bisexual was more plausible, surprising as it was.
It was also possible that this was just a one-time thing.
But when I looked over at Jake, still sleeping on the other side of the bed, I had my doubts about that, too.
Why? Because he had kicked off the covers during the warm night, and the sight of his naked body made my morning wood even woodier.
He lay on his side facing away from me, so I couldn't see that big cock of his, but it was hard not to admire his broad shoulders, well-muscled legs and -- God help me -- his firm, smooth butt.
I felt a twinge in my cock, which in these circumstances was alarming.
I need to get out of here.
I got up as quietly as I could, grabbed my boxers from the floor where I'd tossed them last night, and padded out of the room, closing the door behind me.
In the bathroom I willed my cock down enough to take a long piss. Then I washed my face, feeling another twinge in my dick when I recalled Jake spewing his cum on it a few hours ago.
I put my boxers on and went into the kitchen to put the coffee on. While it was brewing I poured myself a big glass of cold water and drank it straight down, trying to ease my dehydration.
When the coffee was ready I poured half of it into a mug and went out to sit on the deck. Although I was wearing only boxers I was fairly comfortable; it was warm already and would probably be a hot day.
I was halfway through my coffee when I heard the door open and Jake came out, carrying his own mug.
"Morning," he said, plopping into the chair next to me.
"Morning," I responded, but didn't look at him.
A minute or two passed silently. Finally Jake spoke up.
"You okay?"
I paused briefly before saying, "No, I'm not okay."
He took a deep breath.
"Look, Tom, I'm sorry," he said. "I didn't mean to make you uncomfortable. You're my best friend, and I don't want that to change."
I turned and looked at him.
"It has changed," I said. "How could things not change, after that?"
Before he could answer I went on, "And what was 'that,' anyway? I never dreamed you might not be straight, and I sure as hell was never into guys."
Jake took a long drink of coffee.
"I still like women, and always will," he said. "But I found out that sex with guys is fun, too."
I finally looked at him, stunned.
"When did that happen?"
"Well, let's just say I did some experimenting this last year at school."
"Experimenting? What does that mean?"
"Do you really want to know?"
I wasn't sure I did, but I said yes.
"Well, it started when my roommate Ted brought his girlfriend over one night. We all got pretty stoned, and after a while they got up and went to his bedroom. I heard them talking for a minute. Then she came back, took me by the hand and pulled me to my feet.
" 'I'm fucking you both tonight,' she said.
"I was surprised, of course, but I was excited, too, so I followed her.
"In the bedroom I asked Ted, 'Are you okay with this?' and he just shrugged, like he wasn't quite sure what to think, either.
"His girlfriend stripped off her clothes -- she had a magnificent body -- and lay down in the middle of the bed.
" 'Come on, you two," she said.
"Ted and I looked at each other again. I think we were both unsure about how this would go, but we got undressed. We were both super-hard by then, and I couldn't help but notice what a big cock he had.
"We lay down on either side of her. Ted and I took turns making out with her, then we were both feeling her up and fingering her and we got pretty worked up. Suddenly she pushed us away, moved to the foot of the bed and said, 'Before you fuck me, I want to see you guys make out.'
"I was shocked. I hadn't expected this and wasn't sure I liked the idea. I looked at Ted, and I could see he was thinking the same thing.
"But when we looked back at his girlfriend, she was fingering herself with one hand and pinching her nipple with the other. I was desperate to fuck her, and I'm sure Ted was, too.
"I looked back at him. He shrugged again, then scooted a little closer to me. After some hesitation, we kissed lightly.
"C'mon, do it like you mean it," his girlfriend said.
"We kissed again, and this time it was more like the real thing. I was surprised how much we both got into it.
"After we kissed she said she wanted us to touch each other. At first I didn't want to do it, but next thing I know Ted reached over and grabbed my cock.
"It felt great to have another hand on my cock, even if it wasn't a girl's, so I reached over and put my hand on him.
"We stroked each other a few times, and for a second I forgot the girlfriend was even there," Jake said.
"I was afraid she would want us to suck each other," Jake said, "but I guess she had had enough, because she scooted back between us. She made Ted fuck her from behind while she sucked me, then Ted and I switched places. We took turns fucking her for about an hour until we both came twice and she came about five times. Then we all fell asleep.
"When I woke up the next morning the girl was gone and Ted and I were in bed together. I got up and went to my room and slept until noon. When I got up again, Ted was gone. He didn't come back till evening.
"When he came in he sat down and we started talking. He asked me what I thought about last night. I told him the truth; that I had enjoyed it much more than I expected.
" 'All of it?' " he asked.
" 'All of it,' " I said.
" 'Enough to do it again?' he asked.
"I told him yeah, I guess I did.
