Honestly, I want to say no if only because Gray didn't let him near his kits. Granted, when Storm and Feather were big enough to take cock they were in Riverclan, but he didn't even let Fire touch em when they were in Thunderclan for a bit in Darkest Hour. Rude. Also Gray was an ass to him during his whole forbidden romance era.

I imagine Fire's petty so he might've let him watch (or noticed him watching and put on a show) but he didn't ever let him have some. To add insult to injury, he let Dustpelt have free reign of Squirrelpaw
