Jeff wants Emma

It looks like Karen will need a little more work, so you just root her to the spot, while focusing a little on Jeff.

"Wow, she's hot..." Jeff mutters, one hand lightly stroking his already semi erect cock through his trousers.

Karen turns to him, eyes wide. "What the fuck, Jeffery?"

He doesn't reply, but takes a few steps forwards, reaching the edge of the desk and Beth is ready to greet him with a smile. "Let's see it then big boy," she says cooly, her hand running across his crotch for a moment, before letting go, allowing Jeff to fumble with his fly, reaching inside and pulling out his penis.

"Jeffery!" Karen practically screams, looking at him in total shock, stroking his cock at beside the desk.

Beth slides in behind him, wrapping her arms around his waist and jerking him off from behind, pushing him forward a couple more steps before he's literally right next to Emma.

As the two of them reach her, Beth circles again, standing behind Emma now, forcing her down onto her knees, her head almost directly between Jeff and the strangers cocks. Beth again reaches out, one hand clasping each man's shaft, pressing one against each of Emma's cheeks, slowly stroking them back and forth, looking over at Karen. "Are you sure you don't want to get involved?"
