Hey Sister-in-law, Forever With You Is OK With Me... Sumire Shiratori

My wife is pregnant, which is a joyful thing, but because of that, I've been refraining from night activities. However, a young husband's sexual desire has reached its limit and is in a state where it can no longer be suppressed. Amidst this, my wife's older sister comes to live with us, and seeing her voluptuous body up close, I can no longer control my excitement. And my sister-in-law, feeling sorry for the husband, ends up giving him oral sex with the promise that it will be just once.
