Susan has gone from seeing one set of bare breasts (besides her own) in months to two in the span of mere days. Perhaps there is something to this queer little place! Liu Mingyan's are gorgeous, and Susan presses herself back against the door, legs firmly latched around Liu Mingyan's waist so that she can give herself the leverage to frame one with her hand, her thumb and forefinger stretching underneath it, cupping it, just to get a feel for it. Then she brings her hand up so that she can tweak Liu Mingyan's nipple. It's an exploratory pinch, neither as hard as Susan would prefer, nor as soft as someone else might like.
