It all depends on KK's mood. I'm present, and involved for 75% or so of KK's encounters. If I'm present, and she's in the mood for an MFM threesome, I'm a direct participant in the encounter. Other times, KK wants to enjoy a strange cock and just has me watching. I'm almost always stroking if that's the case.
When KK's traveling, or on a solo date, I'm home alone, usually stroking, but not cumming unless that's what KK's instructed. Most of the time, I'm edging, and cum later when we're enjoying reclaiming one another.
