You deserve to stroke for me while she's in the other room, don't you? We both know you cum so much harder for my perfect tits and naughty teases than you ever cum for her. But you are scared of getting caught, aren't you?

Don't worry, this is a reeeally quiet whispered JOI just for you. I'll make sure she never finds out. Now just turn your volume ALL the way up because I'm going to be super quiet while I whisper your jerk off instructions, teasing you and telling you (silently) just how to cum for me.

She'll never know! You can totally trust me.
