Mitsuki Nagisa lives a near-incestuous life with her sister, who allows her to insert her penis up to 3 centimeters deep. (DVAJ-402)

People saw Mitsuki masturbating in her brother's VR. The virgin brothers asked her to let him touch her breasts. Mitsuki was embarrassed to borrow money, so she agreed. I wanted them to not only let me see their breasts, but also their vulvas, and touch and lick my penis... When they finally reached the limit of penetration, they decided on a rule: "Even if you insert a 3cm distance from the tip, it will not be considered sexual intercourse." and began to repeatedly perform neck sex. However, the feeling of pushing the tip of the penis into the vulva was much better, and gradually I wanted to insert it deeper and deeper...!
