The best thing of having an SB is you can just text her when you want to meet up. You know its going to be good sex if you have been ongoing with her for a while and your like good friends. Not all SBs sleep with multiple guys like WLs in shops, some SBs are exclusive. With mine she often lets one of her Asian lady friends join in. All I have to do is text a time and head over to her place. Convenient. No bullshit from her. No time watching.
