Due to my parents' remarriage, I suddenly got a big-breasted stepsister. My stepsister is named Misato and has a carefree personality; she goes braless and unguarded at home. Whenever her breasts peek out, I secretly get an erection. 'Brother, are you maybe a virgin? Never seen boobs before?? Want me to let you touch themw' Angered by the breast provocation mocking me, my desires went into overdrive and I lunged at her... From that day on, taking advantage of my parents' lapses in attention, Misato and I had sex non-stop.
