Nails drug against Greg's chest as Jack whimpered into the kiss, nipping at the man's lip. Of course, two hands doing two different things was a bit hard for Jack (a reason why guitar was something he never really was that good at), so his hand on Julien's length squeezed a bit as his other scratched at Greg. His hips were rolling in slow circles at this point to keep working himself into Jules' hand and he really wanted Greg's shirt off, but that would mean stopping the kiss. He was loathe to do that.
