People usually tell you more about themselves than they mean to, but some behaviors make it easier, and she's on high alert for cues as to what makes Joan happy. Hard pressure on her clit, fond of penetration, check. Beta flips her hand around so she can get two fingers inside Joan, slow and careful, and take that over with the better angle she has so Joan can focus on rubbing herself.
