unfortunately the nipples don't pump as well as the labia. The cups were on the tits for the 2x 10 minutes as well (almost), but the size didn't change. The nips look best after a treatment with smaller cups: still short, but red & hard. Maybe I take some pics next time
it is the often mentioned Froehle cup we are using. The smaller one with the pink edge that is seen in some pictures here fills too fast so we would need to change to a bigger cup anyway after 6 or 8 minutes. This Froehle cup is the one that may be used with the probe ("Sonde") but we discarded that one.
She reported the left labia still being slightly larger 3 hours later when she was with her Yoga group.
