In a forbidden game of virtual reality, two siblings don headsets and enter a hyper-realistic world where their inhibitions are left at the door. The brother's avatar, a muscular, tattooed stud, approaches his sister's petite, lingerie-clad character in a dimly lit, futuristic room. Their avatars embrace, hands exploring each other's virtual bodies, before he lifts her up and presses her against the wall. Her avatar moans as he slides a virtual penis into her, their 3D forms moving in sync with their real-life masturbation.
