Lars has been touch-and-go with eyeing what he's doing to Lauren, so he's been getting the occasional taste of that visual treat. It is indeed super fucking stimulating. When he hears Lauren whimper, Lars's lifts his head a little to stare at Lauren intently. He holds his lower lip in his teeth briefly when he hears Lauren swear, a low moan rumbling through his throat, enthralled that Lars is the one wrangling this behavior out of Lauren. Similar to how Lauren's feeling, really.

He wonders if the sound was from mounting stimulation; the same with the coy drop of Lauren's head. Or if he's looking. Lars leans forward, his lips skimming along the side of Lauren's cheek, just above his jaw, and he slows down the stroking of Lauren's cock tremendously. He can't help but feel a little smug. He's back in his element.

"Yeah?"

One of his hands moves so that Lars's arm closes around Lauren's waist, sort of like Lauren was doing to him earlier—and he holds him like that, his other hand closing around the both of their cocks. He can't encircle them completely, so the sides on one end are bare, but Lars makes do with it well enough, stroking the both of them in a moderate pace. Both of their cocks have produced sufficient precum to make this a little easier. The sensation and the act alone make Lars shudder and groan, feeling...well, decidedly dirty, but in a fun way.
