Suddenly, a super-cute stepsister appeared. As we both got excited about each other's bodies and started to see each other as the opposite sex, our parents went on a one-week trip! Living together alone, my stepsister and I acted like lovers but agreed not to have sex, only dry humping. Until our parents came back, we did it every day! Such a life made my stepsister and me want to insert it so badly. On the last night, we couldn't hold back from edge play dry humping, resulting in wet penetration & bareback ejaculation inside, making us arch our backs and have continuous explosive orgasms!
