He'll recover quickly enough, now that the toy is off, but in the first moment he just pulls back enough to not choke himself further on Phillip's cock and then collapses against him, seems like he's only really still upright because of the way he's on his knees and that gravity is more pulling him straight down than to the side.

"Mmm..." he manages, muzzily but much more coherent than previously, "This was the best idea." He nuzzles into a hip, bites for a moment, but then manages to pull himself off and slowly go about setting them both to rights. "You're going to have to be really careful," he comments, lazily. "Just feeling the thing inside me, now, has me about ready to melt."

That is clearly not a call to stop, though, and he's also clearly not begging yet.
