The second installment  in a 3-part series featuring naughty Nurse Tobi and starving student Justine begins after Justine answers a classified ad for "study subjects" at the Silence is Prosperity Institute (SPI).  Poor Justine remains at the mercy of Tobi while repeatedly bound in the most stringent of hogties and pole-ties with her mouth repeatedly stretched, jacked, packed, and filled with jaw-wrenching gags!  Justine's eyes bulge with the tightness and discomfort of her gags, and her limbs become a marvelous shade of purple as she endures her plight in the name of "science"!  Unbelievable girl-girl footage from our two most requested models as Justine is repeatedly bound and gagged before your eyes!
