A very popular document in which a gentle married woman supports the brush of a virgin. This time, Ayatsuki Natsuyagi, who is popular with her explosive H cup, is here. The virgin is nervous and stiff. On the other hand, this is Ayatsuki's first experience with brushing. We don't know what to do with each other. Relying on their lascivious heart, which is the only thing they have in common, Virgin-kun and Ayatsuki-san challenge the exchange of gachinko's flesh bullets. Will the dream first experience be achieved?
