"How bout I sit? Trust me, it'll make it easier to make out while we're doing this."

Jack climbs onto the bed, sitting against the impressive stack of pillows against the headboard.

"And I, for one, really wanna make out while we do this. But just making out for now, you...you are nowhere near the point you can maintain the right pressure and rhythm and all that shit while I'm pounding you into our mattress."

And Jack realizes after he's said it that he said 'our mattress', not 'mine' or 'the'. Well...it basically is, Steven pretty much lives here and sleeps in Jack's bed and is the only person Jack's sharing his bed with.
