In the morning, Mizutori woke me up in a unique way - by giving a blowjob to my "little brother". Despite my erection, my younger sister stopped her and made me get up to prepare breakfast. Still feeling restless, as Mizutori cooked, I kept teasing her from behind, making my sister unable to resist the urge and had to get into bed with me to satisfy the lust in our bodies before we both started work for a new day.
