The ultimate sex method devised by sex therapist Y, who has evoked "climax power" for many women! This method can increase the sensitivity by accessing the Portio and give a climax that you would not normally feel. This time, we asked AIKA, who has no experience with Portio, to experience the Y-style sex method, and decided to develop Portio! There is no doubt that AIKA will make a full erection with AIKA that feels more than usual and collapses!
