I like being teammate not centre of attention. So, I toss in a bit of structure, but let it kinda riff off of that. So me and lady A double team lady B. Oral things, hopefully get an O out of her. The after that me and lady B double team lady A, hoping to get the O.
Then on with the safety gear and have a go at lady A, with lady B maybe working lady A's boob's or whatever. The change out the safety gear and have a go at Lady B, with lady A doing whatever (one finish was me doing Greek on lady B in doggy whilst she was doing daty on lady A. Didn't take long to blow. Lol ).
One time this structure just broke down and everyone just did whatever and it was Hella fun.
