However,
This day was destined to be one where Mengxi's spirit suffered a tremendous blow.
Because,
The cause of her great psychological trauma wasn't just about that barrier.
Last night,
After trying everything and still failing to break through Yumo's barrier, Mengxi had to temporarily abandon her original goal and comfort Yumo, who was in 'pain' because of her. Since the barrier wasn't breached, all Mengxi could do was to use her fingers and mouth, and grinding movements to appease her sister overwhelmed by desire.
Yumo's breath has the ability to stimulate others' desires.
Under this influence, not only was Mengxi herself drenched in sweat and desire, but Yumo also seemed affected, transforming from a pure big sister to a fearsome juicer, constantly clinging to Mengxi for more pleasure.
