Pushy sub. Not necessarily bottom. That depends on l!"Stephen", and I can see it going either way. (c!"Stephen" definitely prefers being the sub and the bottom, but l!"Stephen" would be way more conscious of the gender roles involved, I think, to not consider switching it up every now and again.)

Don't mind me, really. =P The bottom = sub trope is just a bit of a D/s pet peeve of mine.

(It happens a lot more often than you'd think, too. This was actually something that the D/sverse in other fandoms got so annoyingly wrong; they'd use top/dom and bottom/sub interchangeably, which was headdesk-inducing. Waaaaay too much casual sexism involved in the 'penetration = power' implication necessary for it to be correct and non-*facepalm*-worthy.)
