My big sister is an extremely dominant and aggressive girl who won't let me resist her. Every day, she takes control of my body using various methods to satisfy her sexual desires. She sneaks into my room while I'm asleep, restrains me, and thrusts herself inside without warning. She invades my classroom despite being in a different grade and gives me handjobs. She joins me in the bath and performs titty fucks on me—her boldness knows no limits. Even when she has other lovers over, she shamelessly sets up NTR situations with me. Though our forbidden incestuous relationship should be off-limits, I'm a total masochist who gets turned on and can't refuse her, making me fall for her even more.
