Future Hookups

So, I was in contact with this married straight guy who wanted a blow job, and last month, I finally met him. He was a big ex-cop type, shaved head, etc. He sat down in a chair, and I got on my knees and started licking his balls, and soon had his 6” dick going in and out of my mouth. He was very complimentary of my sucking the whole time. Finally, he had a huge orgasm, and shot 5-6 times in my mouth, which I swallowed.
Yesterday, he contacted me again-he really wants me to suck his cock again. This makes me feel like a gay slut. But, I kind of like it…
