A beautiful transsexual girl has arrived at the "Body Development Research Institute." She is examined by a doctor, who asks her in detail about her erogenous zones, and then the treatment begins. She uses toys to attack every part of her body, including her ears, neck, armpits, back, and nipples. Her penis becomes hard from the pleasure... It is a spectacular sight to see her faint as her anus is destroyed by an extra-thick vibrator and the doctors' penises.
