NHDTB-843 Imprisoned by my step-sister who is unrivaled in bed for reverse NTR, I live with my wife at my parents' place where I secretly get reverse-loved anytime, 24/7

The day before going on a business trip, my cohabiting sister-in-law drugged me with sleeping pills... When I woke up, I was completely restrained! In a state of confinement! Whenever she felt like it, my sister-in-law would seduce me to get me hard and use me as a flesh vibrator! Unable to move, I was made to suck it! Randomly penetrated! Made to ejaculate multiple times!! Forced to have internal ejaculation while sneaking around my wife at home, the thrill and pleasure made me absolutely obedient!!
