MIDA-258 _My lover's big breasted sister came to take shelter from the rain and the ending ended

Takuya and his girlfriend Azu are living together. Today his girlfriend went on a trip with the company, leaving Takuya alone at home. While masturbating, someone suddenly rang the doorbell. It turned out that it suddenly started raining heavily outside, and his lover's older sister Mitsuki was nearby so she wanted to come to his house to shelter from the rain. Because she was soaked, her clothes clung tightly, causing Mitsuki's underwear and H-cup breasts to be exposed, making Takuya unable to take his eyes off. Mitsuki wanted to borrow Azu's clothes to wear temporarily, but Takuya was missing underwear. The thin shirt could not cover Mitsuki's huge breasts, her nipples seemed to appear in front of Takuya.
