I appreciate all the feedback and comments on part 1 and hopefully you all like part 2 just as much (or more!)

I must've passed out shortly after our shared orgasm. I woke up several hours later still naked and covered in (now dry) cum, and I could also feel some still lingering in my ass.
Tim was sleeping naked beside me, his arm over my chest. I desperately wanted to slide out of the bed without him noticing so I could get my things and get out.
I managed to lift his arm and shimmy my way off the bed, and slid out into the living room to get dressed.
As I walked I could feel residual cum oozing and sliding along my crack and no-longer-virginal hole. Something about that feeling stirred my cock a little, but I needed to get home. I'm sure my fiancee had been trying to get ahold of me for hours, and sure enough once I'd slipped on my clothes I checked my phone to find several missed calls and texts wondering where I was.
I slowly made my way up the stairs and out the door into the cool night. How was I going to explain to her why I was out until 4 am and not answering her calls? I decided I'd make up a story about drinking too much and passing out. I figured it was a safe bet.
More importantly, though, how am I going to reconcile with what REALLY happened? I had just let a man pump his seed inside of me, and not only that, I had loved it. I was begging for it, no less. And what did he say again about a test? Something about accepting my homosexuality? It was all so fuzzy.
There was no denying it, though. Last night had been the most pleasurable experience of my life. I had enjoyed sex with my fiancee before, but I'd never felt anything like that, and certainly not recently.
My head was swimming by the time I got to my place. I quietly made my way upstairs and undressed to take a shower. I needed to try to wash everything that had happened away, but I especially needed to not smell like man sex and cum when she smells me.
I vigorously washed my whole body, taking careful effort to try to clean as much residual cum that might be in my hole as I could. While I was doing that I could tell my hole was noticeably looser, and the act of trying to get as much out was starting to feel good as my fingers rubbed on and around my hole.
I started losing myself sliding a finger in and out, and eventually two. My cock was back to its raging rigidity, and I had a moment of clarity again. What was I doing? What the hell was happening to me?
I flipped the water to ice cold and tried to drown the urges away. Eventually I managed to calm down and get out. I just needed some more sleep, I told myself.
My fiancee was indeed asleep in the bed, and as I got in next to her she stirred and looked over at me.
"Where were you all night?"
"I had a few beers and, I don't really know how, but I just fell asleep watching the game. I just woke up and came home."
"Okay... Well... Alright, I guess. Goodnight."
I told her goodnight and rolled over, relieved she had bought it. Within a few minutes I had drifted to sleep.
Over the next few weeks I avoided Tim like the plague. Periodically he'd wave to me as I drove by to or from work, but other than that I made sure to avoid any contact.
I had hoped to chalk things up as a one-off and just move on with things, but that was proving much more difficult than I'd expected.
Every night I would wake up early, around 2 or 3 am with a raging erection, and having just dreamt about being servicing a man (or group of men) and being pumped with cum until I passed out.
When I woke up, I had no choice but to relieve myself, and more and more I was only able to do so while imagining myself taking a man's cock.
It was beginning to consume me. I found myself daydreaming about it at work, and admiring men in my office and around town. Wondering how big their cocks were, and if they had big balls capable of producing big thick loads.
This all culminated one night when my fiancee and I were getting physical. I found myself relatively unaroused during our foreplay, and when it came time for insertion I was almost completely flaccid. It wasn't until I let my mind wander and started wondering if Tim was across the street stroking his big thick cock that I sprang up.
I managed to fake my way through my imagining I was the one lying on their back being fucked like a girl. Imagining all the ways I wanted to be fucked and filled with cum.
It was then that I decided I had to talk to Tim.
The next day I told my fiancee a made up a story about needing to help him with something, and I made my way over.
Tim answered the door with a slight smirk on his face.
