A not-out co-worker has been my toy for years

It started at my old job about a decade ago. I was 19 and he was 22. One of the earliest signs something was up was when one of the warehouse guys made a joke about me having a small dick, and I replied without much thought ‘I’m hung like a horse’.

Apparently that stuck with my co-worker, because he would constantly reference it all the time. About 2 years into the role we ended up sharing an office with just the two of us, and a storage room at the back only accessible from our room. We were in that storage room when he again brought up that comment I made years ago. Without much thought, I pulled my waistband down and showed him my dick. His face went as red as a tomato, and he didn’t know what to do.

A couple days later he text me ‘you weren’t lying’, and the subtext of the conversation was him fishing for more. I didn’t give it to him. Months pass, and we were hanging out at his flat building a gaming PC. He told me out of the blue that he might be gay, and has been on Grindr looking for a dick to suck for the first time. You know where this is going.

Me, being the stand up guy I am, pull my joggers down, and say simply ‘don’t talk, and don’t ever mention this’. He blew me to completion.

This escalates for months, getting handjobs while driving at night, being blown while on hikes, whenever we had a free place etc, until eventually one time I stood up after, and he ‘jokingly’ got on all fours on his bed. That lit a fire in me, and next time he made sure he was prepared. My heart was pounding as I had my tip to his asshole, and to this day nothing has come close to that first sensation, the 15 minutes of warm-up before I managed to get my tip inside him. I have no refractory period, and I spent almost an entire day using his ass and he was in nirvana. It became a fun challenge to see what angles to hit to make him drip pre cum the most before orgasm. I had one rule that he wasn’t allowed to touch himself, because that made it more fun for me.

After a while I changed jobs and we stopped contact, but we picked it up again a few years later. He told me he had tried it again a few times with other guys but it was never the same, he never came and never felt as excited as doing it with me. Since then, we’ve been regularly fucking every few weeks or so. He has a girlfriend, no one else knows, and he comes to me to get pounded to dust. If anyone went into his private gallery, they’d find photos of my cum all over his face, his gaping asshole, and videos of me fucking him like he owes me money.

To this day he’s the only guy I’ve fucked.
