Even for girls whose nipples are more sensitive than others, it seems difficult to cum just with nipple masturbation. one day, a girl whose lower body started to tingle from nipple masturbation clamped a pillow on the bed between her legs. then... the stimulation given to her nipples seemed to travel to the core of her body, and the object clamped in her groin pleasantly rubbed her leg-pinched pussy! with nipple play and leg pinches with something clamped in their groins... the girls cum like crazy from the "core of their bodies"! the content may vary depending on the distribution method.
