I imagine it'd have to be done comic-style, in 1-to-3 pages, depending on how drawn out you make it. Like have Player settling in for some 'fun', then have Carmen in another panel (separated zigzaggy 'telephone' lines) hear him on her coms, but not answer for some contrived reason. Then as he gets more verbal she realizes what's going on and joins in. Then Player either realizes she's heard him (being, during, or after the finish), and they talk about it; or she finishes at the same time as he does, turns off the com and starts planning a way to do something similar again (but perhaps with Player knowing so they can work off of each other).
Oh also Player may optionally be fantasizing about Carmen (maybe muttering about how particular pics/videos look like her, what he'd like to do, etc).
