For a home birth, my wife has returned to her parents' home. Concerned about this, my sister-in-law Ao suddenly visited our house, intending to stay overnight, and even barged into the bath. Despite initially resisting her attractive, slender, and busty body pressing close to me, the long absence from my pregnant wife led us to form a forbidden relationship. However, the sexually frustrated Ao was not satisfied with just one encounter, discarding morality and reputation to pursue her instincts, so I responded by filling her womb with a copious amount of sperm!
