Katie is an amazing friend and we live nearby, but no idea if B and K are going to shoot in the future. They do different things, B has had no desire to do g/g since she flipped to hardcore (her words) and Katie doesn't do hardcore and if she did.... it wouldn't be with us as she's like my little sister. That would be somewhat odd and B and I don't have interest in bringing other girls into our scenes as it is, let alone one we're friends with outside of work... and B won't shoot with other guys (again, her words)
So as of today.. unsure. Sorry I couldn't lie to ya and keep ya guessing.. not my style. if things change though, of course, I will post.
How about this idea? Katie and Bryci start with some kissing and foreplay, but then you and Bryci get comfortable and Katie is in the background watching. And then when things get more interesting between you and Bryci, Katie starts touching herself. Then as you and Bryci get into the b/g part, Katie will be fully on naked and masturbating.
That could work, couldn't it? Bryci would just be kissing and maybe some light touching, not actual g/g, and Katie would just be watching the hardcore part, not actually participating.
