"From today, it's my big brother's breasts! Both of them..." I licked my growing younger sister's breasts, which I own, and sucked, rubbed, and licked them all over again!

My little sister has suddenly become bigger recently. What's more, she dresses extremely defenselessly, so her gaze is concentrated on her breasts and even gets an erection... "What, Big Brother, have you been bothered by my breasts and your penis has become big?" And then I was told that, and couldn't see my sister's face properly, and another comment was given to me, "These are both big brother's breasts from today." I was honestly spoiled and I was able to love the two breasts that became my property.
