HUNTB-469 Make them drink my cum with both their mouths! These two sisters are my personal cum-swallowing pets! Whenever I feel like fucking, I can make them do whatever I want and have them drink my cum to their hearts' content! Cum inside them to my hea

My parents both work, so our house is often empty. Because of this situation, I've been educating my younger sisters in various ways since they were little. Of course, things that would drive our parents crazy if they found out. Things that are completely unrelated to time, place, or circumstances; as soon as I call out, they immediately become super capable slutty sisters who give head. Thanks to this, now whenever I feel like having sex, I can go all the way instantly. However, it was an unexpected miscalculation that their excessive erotic education turned them into slight erotic monsters, but I'm making good use of them as dildo substitutes!
