I had a delayed reaction the first time I indulged in cockplay. Delayed, like by weeks or even months.
I was the photographer for a very nice couple. I had no physical interaction with them, the (very horny) setup was that I got naked and took photos and videos, occasionally wanking and getting my cock in shot, while they had sex.
After our third or fourth meeting, they asked if he could suck my cock as it was something he wanted to try and she wanted to see. I hadn't considered it before then, but I thought about it, and as I like making fantasies happen I said okay, but I wouldn't be returning the favour. So, next time we got together, in the middle of playing with her, he reached over, gave me a stroke, then put me in his mouth and gave it a damn good suck and lick.
Now, my immediate reaction was that it didn't do much for me. I liked that he got into it, and that she had a big smile on her face and looked turned on by it, but I didn't get turned on. Don't get me wrong, it didn't turn me off, but overall it just felt like something that happened, like a handshake, lol, rather than how I'd react to a BJ from a woman. But I was glad I'd helped them tick this particular fantasy box.
We met once more and again he sucked me, and this time he almost made me cum. In fact I had to pull out of his mouth to prevent that. He was fucking her on her back on the bed while sucking me as I stood straddling her. I was filming, looking straight down, and I remember the shot - him sucking me, while in the background she had a huge smile on her face as she looked up at the action, which is probably what did it for me! I was concerned, though, that if I came she might get some on her as I was standing over her.
At this point, though, I still felt like being sucked by a guy didn't really push my buttons.
However, over the next few weeks and months, I kept thinking back to it. And I had the video of that first BJ to look at, which I found more and more of a turn-on. I started actively looking for NN video clips that included threesome cockplay, and my curiosity about not only being sucked again, but doing some sucking myself, grew.
Unfortunately, the couple and I didn't meet again, as they'd decided not to have a photographer, so that wasn't an option. But then I got chatting with UKLiz and her husband, and eventually we decided to meet.
By the time I slid my cock into Liz for the first time, and at the same time took her husband's hard cock first in my hand and then in my mouth, I had no doubts that this was something I wanted to do. No hesitation. His cock (and two or three others) has been sucked by me several times since then.
I still think back to that first time, even the first couple of times, and think how odd it was that it didn't immediately turn me on or really push my buttons in any way. But now I love it, it really adds to the fun, and I'm forever grateful that that couple asked if I'd mind very much if he could suck me.
