S1's new surprise project second round features the popular actress saika kawakita! While there have been projects based on her true self before, this time it's unannounced immediate fucking, allowing you to see a variety of expressions from joy to sorrow! By sharing the manager's schedule, we insert male actors into the gaps of daily life, and suddenly insert cocks for a quick fuck! Sometimes surprised, sometimes reluctant, but always feeling it, saika's raw and erotic figure is unbearable!
