Nijimura Yumi’s nipples are already her erogenous zone, so we start nipple training to make them even more sensitive! When she’s blindfolded and deprived of her vision, Nijimura’s senses become sharper, and she already has a big stain on her panties. As we tease her nipples and tease her pussy with toys, she cums repeatedly in no time. Now that she’s become a complete masochist, we train her with raw insertion and creampie, and when we further increase her sensitivity with nipple teasing toys, she climaxes just from nipple teasing. When we insert her when her body is already at its peak of sensitivity, she squirts a huge amount of cum. Nijimura Yumi, who looks great with her short hair, is completely addicted to nipple training.
