Among schoolgirl friends, a once-rare sight has become increasingly common. This is not mere mutual masturbation, but a twisted act where they insert fingers into each other's vaginas. These girls seem to prefer seeking pleasure under someone else's control rather than enjoying themselves alone. Unashamedly exposing their private parts, they carefully wet each other's vulvas and revel in the sensations. They lewdly touch and stimulate each other's vaginas, building intense arousal until they reach climax. This scene stands at the intersection of deep emotional bonds and raw desire, surpassing pure friendship.
