A complete lack of shame or societal concern about overdoing it is a hell of a drug. Or just very convenient for being Charlie's own personal porn played out in their bed accidentally.

The timing in dreams is, of course, different from the timing in the waking world, so even if Charlie has no idea how much time has passed since this all started, it's abundantly clear that dream!Charlie is fucking John like it's his job, and John's getting close. His horns are pushing up against the pillows, the dream keeping his movements short and half finished, but Charlie will get to watch it happen: he strains upwards and the breath is punched out of him as his cock shoots over his belly, his chest, up along his face and jaw, every drop catching the light in shimmering gold against the darkness.
