Joshua, the nerdy stepbrother, finds himself in a tutoring session unlike any other. Eve, his sultry step-sister, insists on learning more than just academics. She's curious about the ropes, both literal and metaphorical, that bind their bodies together.

Joshua, nervous but eager, guides her through the pleasures of the flesh, his voice shaking as he explains each step.
